+Bugs in GNU Fortran
+*******************
+
+   This section identifies bugs that `g77' *users* might run into in
+the `egcs'-1.1.2 version of `g77'.  This includes bugs that are
+actually in the `gcc' back end (GBE) or in `libf2c', because those sets
+of code are at least somewhat under the control of (and necessarily
+intertwined with) `g77', so it isn't worth separating them out.
+
+   For information on bugs in *other* versions of `g77', see
+`egcs/gcc/f/NEWS'.
+
+   An online, "live" version of this document (derived directly from
+the up-to-date mainline version of `g77' within `egcs') is available at
+`http://egcs.cygnus.com/onlinedocs/g77_bugs.html'.
+
+   For information on bugs that might afflict people who configure,
+port, build, and install `g77', see "Problems Installing" in
+`egcs/gcc/f/INSTALL'.
+
+   * `g77' generates bad code for assignments, or other conversions, of
+     `REAL' or `COMPLEX' constant expressions to type `INTEGER(KIND=2)'
+     (often referred to as `INTEGER*8').
+
+     For example, `INTEGER*8 J; J = 4E10' is miscompiled on some
+     systems--the wrong value is stored in J.
+
+   * The `IDate' Intrinsic (VXT) fails to return the year in the
+     documented, non-Y2K-compliant range of 0-99, instead returning 100
+     for the year 2000.
+
+   * Year 2000 (Y2K) compliance information is missing from the
+     documentation.
+
+   * `g77' crashes when compiling I/O statements using keywords that
+     define `INTEGER' values, such as `IOSTAT=J', where J is other than
+     default `INTEGER' (such as `INTEGER*2').
+
+   * The `-ax' option is not obeyed when compiling Fortran programs.
+     (It is not passed to the `f771' driver.)
+
+   * `g77' fails to warn about a reference to a function when the
+     corresponding *subsequent* function program unit disagrees with
+     the reference concerning the type of the function.
+
+   * Automatic arrays possibly aren't working on HP-UX systems, at
+     least in HP-UX version 10.20.  Writing into them apparently causes
+     over-writing of statically declared data in the main program.
+     This probably means the arrays themselves are being
+     under-allocated, or pointers to them being improperly handled,
+     e.g. not passed to other procedures as they should be.
+
+   * `g77' fails to warn about use of a "live" iterative-DO variable as
+     an implied-DO variable in a `WRITE' or `PRINT' statement (although
+     it does warn about this in a `READ' statement).
+
+   * Something about `g77''s straightforward handling of label
+     references and definitions sometimes prevents the GBE from
+     unrolling loops.  Until this is solved, try inserting or removing
+     `CONTINUE' statements as the terminal statement, using the `END DO'
+     form instead, and so on.
+
+   * Some confusion in diagnostics concerning failing `INCLUDE'
+     statements from within `INCLUDE''d or `#include''d files.
+
+   * `g77' assumes that `INTEGER(KIND=1)' constants range from `-2**31'
+     to `2**31-1' (the range for two's-complement 32-bit values),
+     instead of determining their range from the actual range of the
+     type for the configuration (and, someday, for the constant).
+
+     Further, it generally doesn't implement the handling of constants
+     very well in that it makes assumptions about the configuration
+     that it no longer makes regarding variables (types).
+
+     Included with this item is the fact that `g77' doesn't recognize
+     that, on IEEE-754/854-compliant systems, `0./0.' should produce a
+     NaN and no warning instead of the value `0.' and a warning.  This
+     is to be fixed in version 0.6, when `g77' will use the `gcc' back
+     end's constant-handling mechanisms to replace its own.
+
+   * `g77' uses way too much memory and CPU time to process large
+     aggregate areas having any initialized elements.
+
+     For example, `REAL A(1000000)' followed by `DATA A(1)/1/' takes up
+     way too much time and space, including the size of the generated
+     assembler file.  This is to be mitigated somewhat in version 0.6.
+
+     Version 0.5.18 improves cases like this--specifically, cases of
+     *sparse* initialization that leave large, contiguous areas
+     uninitialized--significantly.  However, even with the
+     improvements, these cases still require too much memory and CPU
+     time.
+
+     (Version 0.5.18 also improves cases where the initial values are
+     zero to a much greater degree, so if the above example ends with
+     `DATA A(1)/0/', the compile-time performance will be about as good
+     as it will ever get, aside from unrelated improvements to the
+     compiler.)
+
+     Note that `g77' does display a warning message to notify the user
+     before the compiler appears to hang.
+
+   * `g77' doesn't emit variable and array members of common blocks for
+     use with a debugger (the `-g' command-line option).  The code is
+     present to do this, but doesn't work with at least one debug
+     format--perhaps it works with others.  And it turns out there's a
+     similar bug for local equivalence areas, so that has been disabled
+     as well.
+
+     As of Version 0.5.19, a temporary kludge solution is provided
+     whereby some rudimentary information on a member is written as a
+     string that is the member's value as a character string.
+
+   * When debugging, after starting up the debugger but before being
+     able to see the source code for the main program unit, the user
+     must currently set a breakpoint at `MAIN__' (or `MAIN___' or
+     `MAIN_' if `MAIN__' doesn't exist) and run the program until it
+     hits the breakpoint.  At that point, the main program unit is
+     activated and about to execute its first executable statement, but
+     that's the state in which the debugger should start up, as is the
+     case for languages like C.
+
+   * Debugging `g77'-compiled code using debuggers other than `gdb' is
+     likely not to work.
+
+     Getting `g77' and `gdb' to work together is a known
+     problem--getting `g77' to work properly with other debuggers, for
+     which source code often is unavailable to `g77' developers, seems
+     like a much larger, unknown problem, and is a lower priority than
+     making `g77' and `gdb' work together properly.
+
+     On the other hand, information about problems other debuggers have
+     with `g77' output might make it easier to properly fix `g77', and
+     perhaps even improve `gdb', so it is definitely welcome.  Such
+     information might even lead to all relevant products working
+     together properly sooner.
+
+   * `g77' doesn't work perfectly on 64-bit configurations such as the
+     Digital Semiconductor ("DEC") Alpha.
+
+     This problem is largely resolved as of version 0.5.23.  Version
+     0.6 should solve most or all remaining problems (such as
+     cross-compiling involving 64-bit machines).
+
+   * Maintainers of gcc report that the back end definitely has "broken"
+     support for `COMPLEX' types.  Based on their input, it seems many
+     of the problems affect only the more-general facilities for gcc's
+     `__complex__' type, such as `__complex__ int' (where the real and
+     imaginary parts are integers) that GNU Fortran does not use.
+
+     Version 0.5.20 of `g77' works around this problem by not using the
+     back end's support for `COMPLEX'.  The new option
+     `-fno-emulate-complex' avoids the work-around, reverting to using
+     the same "broken" mechanism as that used by versions of `g77'
+     prior to 0.5.20.
+
+   * `g77' currently inserts needless padding for things like `COMMON
+     A,IPAD' where `A' is `CHARACTER*1' and `IPAD' is `INTEGER(KIND=1)'
+     on machines like x86, because the back end insists that `IPAD' be
+     aligned to a 4-byte boundary, but the processor has no such
+     requirement (though it is usually good for performance).
+
+     The `gcc' back end needs to provide a wider array of
+     specifications of alignment requirements and preferences for
+     targets, and front ends like `g77' should take advantage of this
+     when it becomes available.
+
+   * The x86 target's `-malign-double' option no longer reliably aligns
+     double-precision variables and arrays when they are placed in the
+     stack frame.
+
+     This can significantly reduce the performance of some applications,
+     even on a run-to-run basis (that is, performance measurements can
+     vary fairly widely depending on whether frequently used variables
+     are properly aligned, and that can change from one program run to
+     the next, even from one procedure call to the next).
+
+     Versions 0.5.22 and earlier of `g77' included a patch to `gcc'
+     that enabled this, but that patch has been deemed an improper
+     (probably buggy) one for version 2.8 of `gcc' and for `egcs'.
+
+     Note that version 1.1 of `egcs' aligns double-precision variables
+     and arrays when they are in static storage even if
+     `-malign-double' is not specified.
+
+     There is ongoing investigation into how to make `-malign-double'
+     work properly, also into how to make it unnecessary to get all
+     double-precision variables and arrays aligned when such alignment
+     would not violate the relevant specifications for processor and
+     inter-procedural interfaces.
+
+     For a suite of programs to test double-precision alignment, see
+     `ftp://alpha.gnu.org/gnu/g77/align/'.
+
+   * The `libf2c' routines that perform some run-time arithmetic on
+     `COMPLEX' operands were modified circa version 0.5.20 of `g77' to
+     work properly even in the presence of aliased operands.
+
+     While the `g77' and `netlib' versions of `libf2c' differ on how
+     this is accomplished, the main differences are that we believe the
+     `g77' version works properly even in the presence of *partially*
+     aliased operands.
+
+     However, these modifications have reduced performance on targets
+     such as x86, due to the extra copies of operands involved.

+	(g77version.o): New rule to compile g77 version info.
+	(g77$(exeext)): Depend on and link in g77version.o.
+	* g77spec.c: Rewrite to be more like 0.5.22 version
+	of g77.c, making filtering of command line smarter
+	so mixed Fortran and C (etc.) can be compiled, verbose
+	version info can be obtained, etc.
+	* lang-specs.h (f77-version): New "language" to support
+	"g77 -v" command under new gcc 2.8 regime.

+	f77.uninstall, $(G77STAGESTUFF), f77.stage1, f77.stage2,
+	f77.stage3, f77.stage4, f77.distdir): Don't do anything
+	unless user specified "f77" or "F77" in $LANGUAGES either
+	during configuration or explicitly.  For convenience of
+	various tests and to work around lack of the assignment
+	"LANGUAGES=$(BOOT_LANGUAGES)" in the "make stage1" command
+	of "make bootstrap" in gcc, use a touch file named "lang-f77"
+	to communicate whether this is the case.
+

+
+	Rename libf2c.a and f2c.h to libg2c.a and g2c.h,

+	* Make-lang.in: Remove all support for overwriting
+	/usr/bin/f77 etc., or whatever the actual names are
+	via $(prefix) and $(local_prefix).  (g++ overwrites
+	/usr/bin/c++, but then it's often the only C++ compiler
+	on the system; f77 often exists on systems that are
+	installing g77.)
+	(f77.realclean): Remove obsolete target.
+	(g77.c, g77$(exeext)): Minor changes to look more like g++'s
+	stuff.
+	(f771): Now built with srcdir=gcc/f, not srcdir=gcc, to be

+	(none): Remove.
+	(g77-only): Relocate.
+	(all.indirect, f771, *.o): Now assumes current directory
+	is this dir (gcc/f), not the parent directory.
+	(TAGS): Remove "echo 'parse.y,0'  >> TAGS ;" line.
+	* config-lang.in: Delete commented-out code.
+	Fix stagestuff definition.  Add more stuff to
+	diff_excludes definition.  Don't create any directories.
+	Set outputs to f/Makefile, to get variable substition
+	to happen (what does that really do, anyway?!).
+	* g77spec.c: Rename libf2c to libg2c.
+
+	* com.h: Remove all of the gcc back-end decls,
+	since egcs should have all of them correct.
+
+	* com.c: Include "proj.h" before anything else,
+	as that's how things are supposed to work.
+	* ste.c: Ditto.
+
+	* bad.c: Include "flags.j" here, since some diagnostics
+	check flag_pedantic_errors.
+
+	* Makefile.in (f/*.o): Rebuild dependencies via
+	deps-kinda.
+
+	* output.j: New source file.
+	* Make-lang.in (F77_SRCS): Update accordingly.

+	not convert (DOUBLE PRECISION) D and (DOUBLE COMPLEX) Z
+	to INTEGER.  (This is dead code here anyway.)
+
+Sat May 23 06:32:52 1998  Craig Burley  <burley@gnu.org>
+
+	* com.c (ffecom_finish_symbol_transform_): Don't transform
+	statement (nested) functions, to avoid gcc compiling them
+	and thus producing linker errors if they refer to undefined
+	external functions.  But warn if they're unused and -Wunused.
+	* bad.def (FFEBAD_SFUNC_UNUSED): New diagnostic.
+
+Wed May 20 12:12:55 1998  Craig Burley  <burley@gnu.org>

+
+	Fix up problems when virtual memory exhausted:

+	* com.c (ffecom_expr_intrinsic_) (case FFEINTRIN_impALARM):
+	No need to test codegen_imp -- there's only one valid here.
+

+
+Fri Aug  8 05:40:23 1997  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	Substantial changes to accommodate distinctions among
+	run-time routines that support intrinsics, and between
+	routines that compute and return the same type vs. those
+	that compute one type and return another (or `void'):
+	* com-rt.def: Specify new return type REAL_F2C_ instead
+	of many DOUBLE_, COMPLEX_F2C_ instead of COMPLEX_, and
+	so on.
+	Clear up the *BES* routines "once and for all".
+	* com.c: New return types.
+	(ffecom_convert_narrow_, ffecom_convert_widen_):
+	New functions that are "safe" variants of convert(),
+	to catch errors that ffecom_expr_intrinsic_() now
+	no longer catches.
+	(ffecom_arglist_expr_): Ensure arguments are not
+	converted to narrower types.
+	(ffecom_call_): Ensure return value is not converted
+	to a wider type.
+	(ffecom_char_args_): Use new ffeintrin_gfrt_direct()
+	routine.
+	(ffecom_expr_intrinsic_): Simplify how run-time
+	routine is selected (via `gfrt' only now; lose the
+	redundant `ix' variable).
+	Eliminate the `library' label; any code that doesn't
+	return directly just `break's out now with `gfrt'
+	set appropriately.
+	Set `gfrt' to default choice initially, either a
+	fast direct form or, if not available, a slower
+	indirect-callable form.
+	(ffecom_make_gfrt_): No longer need to do special
+	check for complex; it's built into the new return-type
+	regime.
+	(ffecom_ptr_to_expr): Use new ffeintrin_gfrt_indirect()
+	routine.
+	* intrin.c, intrin.h: `gfrt' field replaced with three fields,
+	so it is easier to provide faster direct-callable and
+	GNU-convention indirect-callable routines in the future.
+	DEFIMP macro adjusted accordingly, along with all its uses.
+	(ffeintrin_gfrt_direct): New function.
+	(ffeintrin_gfrt_indirect): Ditto.
+	(ffeintrin_is_actualarg): If `-fno-f2c' is in effect,
+	require a GNU-callable version of intrinsic instead of
+	an f2c-callable version, so indirect calling is still checked.
+	* intrin.def: Replace one GFRT field with the three new fields,
+	as appropriate for each DEFIMP intrinsic.
+
+	* com.c (ffecom_stabilize_aggregate_,
+	ffecom_convert_to_complex_): Make these `static'.
+
+Thu Aug  7 11:24:34 1997  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	Provide means for front end to determine actual
+	"standard" return type for an intrinsic if it is

+	ffecom_gfrt_kindtype): New functions.
+	(ffecom_gfrt_kind_type_): Replaced with new function.
+	All callers updated.
+	(ffecom_make_gfrt_): No longer need do anything
+	with kind type.
+
+	* intrin.c (ffeintrin_basictype, ffeintrin_kindtype):
+	Now returns correct type info for specific intrinsic
+	(based on type of run-time-library implementation).
+
+Wed Aug  6 23:08:46 1997  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	* global.c (ffeglobal_ref_progunit_): Don't reset
+	number of arguments just due to new type info,
+	so useful warnings can be issued.
+
+1997-08-06  Dave Love  <d.love@dl.ac.uk>
+
+	* intrin.def: Fix IDATE_vxt argument order.
+	* intdoc.h: Likewise.
+
+Thu Jul 31 22:22:03 1997  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	* global.c (ffeglobal_proc_ref_arg): If REF/DESCR
+	disagreement, DESCR is CHARACTER, and types disagree,
+	pretend the argsummary agrees so the message ends up
+	being about type disagreement.
+	(ffeglobal_proc_def_arg): Ditto.
+
+	* expr.c (ffeexpr_token_first_rhs_3_): Set info for LABTOK
+	to NONE of everything, to avoid misdiagnosing filewide
+	usage of alternate returns.
+
+Sun Jul 20 23:07:47 1997  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	* com.c (ffecom_sym_transform_): If type gets set
+	to error_mark_node, just return that for transformed symbol.
+	(ffecom_member_phase2_): If type gets set to error_mark_node,
+	just return.
+	(ffecom_check_size_overflow_): Add `dummy' argument to
+	flag that type is for a dummy, update all callers.
+
+Sun Jul 13 17:40:53 1997  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	Fix 970712-1.f:
+	* where.c (ffewhere_set_from_track): If start point

+	fix all this properly.
+
+	Fix 970712-2.f:
+	* com.c (ffecom_sym_transform_): Preserve error_mark_node for type.
+	(ffecom_type_localvar_): Ditto.
+	(ffecom_sym_transform_): If type is error_mark_node,
+	don't error-check decl size, because back end responds by
+	setting that to an integer 0 instead of error_mark_node.
+	(ffecom_transform_common_): Same as earlier fix to _transform_
+	in that size is checked by dividing BITS_PER_UNIT instead of
+	multiplying.
+	(ffecom_transform_equiv_): Ditto.
+
+	Fix 970712-3.f:
+	* stb.c (ffestb_R10014_): Fix flaky fall-through in error
+	test for FFELEX_typeCONCAT by just replicating the code,
+	and do FFELEX_typeCOLONCOLON while at it.
+
+1997-07-07  Dave Love  <d.love@dl.ac.uk>
+
+	* intdoc.h: Add various missing pieces; correct GMTIME, LTIME

+	* com.c (ffecom_expr_intrinsic_): Add case for alarm.
+
+Thu Jun 26 04:19:40 1997  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	Fix 970302-3.f:
+	* com.c (ffecom_sym_transform_): For sanity-check compare
+	of gbe size of local variable to g77 expectation,
+	use varasm.c/assemble_variable technique of dividing
+	BITS_PER_UNIT out of gbe info instead of multiplying
+	g77 info up, to avoid crash when size in bytes is very
+	large, and overflows an `int' or similar when multiplied.
+
+	Fix 970626-2.f:
+	* com.c (ffecom_finish_symbol_transform_): Don't bother
+	transforming a dummy argument, to avoid a crash.
+	* ste.c (ffeste_R1227): Don't return a value if the
+	result decl, or its type, is error_mark_node.
+
+	Fix 970626-4.f:
+	* lex.c (ffelex_splice_tokens): `-fdollar-ok' is
+	irrelevant to whether a DOLLAR token should be made
+	from an initial character of `$'.
+
+	Fix 970626-6.f:
+	* stb.c (ffestb_do3_): DO iteration variable is an
+	lhs, not rhs, expression.
+
+	Fix 970626-7.f and 970626-8.f:
+	* expr.c (ffeexpr_cb_comma_i_1_): Set IMPDO expression
+	to have clean info, because undefined rank, for example,
+	caused crash on mangled source on UltraSPARC but not
+	on Alpha for a series of weird reasons.
+	(ffeexpr_cb_close_paren_): If not CLOSE_PAREN, push
+	opANY expression onto stack instead of attempting
+	to mimic what program might have wanted.
+	(ffeexpr_cb_close_paren_): Don't wrap opPAREN around
+	opIMPDO, just warn that it's gratuitous.
+	* bad.def (FFEBAD_IMPDO_PAREN): New warning.
+
+	Fix 970626-9.f:
+	* expr.c (ffeexpr_declare_parenthesized_): Must shut down
+	parsing in kindANY case, otherwise the parsing engine might
+	decide there's an ambiguity.
+	(ffeexpr_token_name_rhs_): Eliminate parentypeSUBROUTINE_
+	case, so we crash right away if it comes through.
+	* st.c, st.h, sta.c, sta.h (ffest_shutdown, ffesta_shutdown):
+	New functions.
+
+Tue Jun 24 19:47:29 1997  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	* com.c (ffecom_check_size_overflow_): New function
+	catches some cases of the size of a type getting

+	* global.c (ffeglobal_proc_def_arg): Fix comparison
+	of argno to #args.
+	(ffeglobal_proc_ref_arg): Ditto.
+
+	* lang-options.h, top.c: Rename `-fdebug' to `-fxyzzy',
+	since it's an unsupported internals option and some
+	poor user might guess that it does something.
+
+	* bad.def: Make a warning for each filewide diagnostic.
+	Put all filewides together.
+	* com.c (ffecom_sym_transform_): Don't substitute
+	known global tree for global entities when `-fno-globals'.
+	* global.c (ffeglobal_new_progunit_): Don't produce
+	fatal diagnostics about globals when `-fno-globals'.
+	Instead, produce equivalent warning when `-Wglobals'.
+	(ffeglobal_proc_ref_arg): Ditto.
+	(ffeglobal_proc_ref_nargs): Ditto.
+	(ffeglobal_ref_progunit_): Ditto.
+	* lang-options.h, top.c, top.h: New `-fno-globals' option.

+
+	* expr.c (ffeexpr_fulfill_call_): Set array variable
+	to avoid warning about uninitialized variable.
+
+	* Make-lang.in: Get rid of any setting of HOST_* macros,

+	easier.
+
+Thu Jun 19 18:19:28 1997  Craig Burley  <burley@gnu.ai.mit.edu>

+

+
+	* intdoc.c: Add cross-reference to end of description

+
+	* com.c (ffecom_init_0): Pointer type is now INTEGER(KIND=7),
+	not INTEGER(KIND=0), since we want to reserve KIND=0 for
+	future use.
+
+Thu May 29 14:30:33 1997  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	Fix bugs preventing CTIME(I*4) from working correctly:
+	* com.c (ffecom_char_args_): For FUNCREF case, process

+	* global.h: Ditto.
+	* expr.c (ffeexpr_fulfill_call_): A SYMTER with kindNONE

+	specific to .NOT. now mention only one operand instead
+	of two.

+	from being recognized.

+
+	* intrin.def (FFEINTRIN_impCTIME): Accept `I*' expression
+	for STime instead of requiring `I2'.
+
+Tue May 20 16:14:40 1997  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	* symbol.c (ffesymbol_reference): All references to
+	standard intrinsics are considered explicit, so as
+	to avoid generating basically useless warnings.
+	* intrin.c, intrin.h (ffeintrin_is_standard): Returns TRUE
+	if intrinsic is standard.
+
+Sun May 18 21:14:59 1997  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	* com-rt.def: Changed all external names of the
+	form `"\([a-z0-9]*\)_' to `"G77_\1_0"' so as to
+	allow any name valid as an intrinsic to be used
+	as such and as a user-defined external procedure
+	name or common block as well.

+

+
+	* intrin.def (FFEINTRIN_defSIGNAL): Add optional `Status'

+
+	More changes to support better tracking of (filewide)
+	globals:
+	* expr.c (ffeexpr_fulfill_call_): New function.

+	reference expression.  Also leave info field for ANY-ized

+
+Mon Apr 28 20:04:18 1997  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	Changes to support better tracking of (filewide)

+	* global.c (ffeglobal_type_string_): New array for
+	new diagnostics.
+	* global.h, global.c:
+	Replace ->init mechanism with ->tick mechanism.
+	Move other common-related members into a substructure of
+	a union, so the proc substructure can be introduced
+	to include members related to externals other than commons.
+	Don't complain about ANY-ized globals; ANY-ize globals
+	once they're complained about, in any case where code
+	generation could become a problem.
+	Handle global entries that have NONE type (seen as
+	intrinsics), EXT type (seen as EXTERNAL), and so on.
+	Keep track of kind and type of externals, both via

+	Diagnose disagreements about kind or type of externals
+	(such as functions).

+	* symbol.c (ffesymbol_globalize): Removed...
+	(ffesymbol_reference): ...to this new function,
+	which more generally registers references to symbols,
+	globalizes globals, and calls on the ffeglobal module
+	to check globals filewide.
+
+	* global.h, global.c: Rename some macros and functions
+	to more clearly distinguish common from other globals.
+	All callers changed.
+
+	* com.c (ffecom_sym_transform_): Trees describing

+
+	* expr.c (ffeexpr_token_name_lhs_): Don't generate

+	happen later.
+
+	* stb.c (ffestb_R10014_): If NAMES isn't recognized (or
+	the recognized part is followed in the token by a
+	non-digit), don't try and collect digits, as there
+	might be more than FFEWHERE_indexMAX letters to skip
+	past to do so -- and the code is diagnosed anyway.
+
+Thu Mar 27 00:02:48 1997  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	* com.c (ffecom_sym_transform_): Force local

+
+	* lex.c (ffelex_image_char_): Avoid overflowing the
+	column counter itself, as well as the card image.
+
+	* where.c (ffewhere_line_new): Cast ffelex_line_length()
+	to (size_t) so 255 doesn't overflow to 0!
+
+	* stc.c (ffestc_labeldef_notloop_begin_): Don't gratuitously
+	terminate loop before processing statement, so block
+	doesn't disappear out from under EXIT/CYCLE processing.
+	(ffestc_labeldef_notloop_): Has old code from above
+	function, instead of just calling it.
+
+	* expr.c (ffeexpr_cb_comma_i_4_): Don't skip over
+	arbitrary token (such as EOS).
+
+	* com.c (ffecom_init_zero_): Handle RECORD_TYPE and
+	UNION_TYPE so -fno-zeros works with -femulated-complex.
+
+1997-03-12  Dave Love  <d.love@dl.ac.uk>
+
+	* intrin.def: New intrinsics INT2, INT8, CPU_TIME.  Fix AND, OR,
+ 	XOR.  [Integrated by burley, AND/OR/XOR already fixed, INT8
+	implementation changed/fixed.]
+
+Wed Mar 12 10:40:08 1997  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	* Make-lang.in ($(srcdir)/f/intdoc.texi): Simplify rules
+	so building f/intdoc is not always necessary; remove
+	f/intdoc after running it if it is built.
+
+Tue Mar 11 23:42:00 1997  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	* intrin.def (FFEINTRIN_impAND, FFEINTRIN_impOR,
+	FFEINTRIN_impXOR): Use the IAND, IOR, and IEOR implementations
+	of these, instead of crashing in ffecom_expr_intrinsic_
+	or adding case labels there.
+
+Mon Mar 10 22:51:23 1997  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	* intdoc.c: Fix so any C compiler can compile this.
+
+Fri Feb 28 13:16:50 1997  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	* Version 0.5.20 released.
+
+Fri Feb 28 01:45:25 1997  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	* Make-lang.in (RUNTIMESTAGESTUFF, LIBU77STAGESTUFF):
+	Move some files incorrectly in the former to the latter,
+	and add another file or two to the latter.
+
+	New meanings for (KIND=n), and new denotations in the
+	little language describing intrinsics:
+	* com.c (ffecom_init_0): Assign new meanings.
+	* intdoc.c: Document new meanings.
+	Support the new denotations.
+	* intrin.c: Employ new meanings, mapping them to internal
+	values (which are the same as they ever were for now).
+	Support the new denotations.
+	* intrin.def: Switch DEFIMP table to the new denotations.
+
+	* intrin.c (ffeintrin_check_): Fix bug that was leaving
+	LOC() and %LOC() returning INTEGER*4 on systems where
+	it should return INTEGER*8.
+
+	* type.c: Canonicalize function definitions, for etags
+	and such.
+
+Wed Feb 26 20:43:03 1997  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	* com.c (ffecom_init_0): Choose INTEGER(KIND=n) types,
+	where n is 2, 3, and 4, according to the new docs
+	instead of according to the old C correspondences
+	(which seem less useful at this point).
+
+	* equiv.c (ffeequiv_destroy_): New function.
+	(ffeequiv_layout_local_): Use this new function
+	whenever the laying out of a local equivalence chain
+	is aborted for any reason.
+	Otherwise ensure that symbols no longer reference
+	the stale ffeequiv entries that result when they
+	are killed off in this procedure.
+	Also, the rooted symbol is one that has storage,
+	it really is irrelevant whether it has an equiv entry
+	at this point (though the code to remove the equiv
+	entry was put in at the end, just in case).
+	(ffeequiv_kill): When doing internal checks, make
+	sure the victim isn't named by any symbols it points
+	to.  Not as complete a check as looking through the
+	entire symbol table (which does matter, since some
+	code in equiv.c used to remove symbols from the lists
+	for an ffeequiv victim but not remove that victim as the
+	symbol's equiv info), but this check did find some
+	real bugs in the code (that were fixed).
+
+Mon Feb 24 16:42:13 1997  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	* com.c (ffecom_expr_intrinsic_): Fix a couple of

+	(FFEBAD_INTRINSIC_CMPAMBIG): New.
+	* intrin.c (ffeintrin_fulfill_generic,
+	ffeintrin_fulfill_specific, ffeintrin_is_intrinsic):
+	Always choose
+	generic or specific name text (which is for doc purposes
+	anyway) over implementation name text (which is for
+	internal use).
+	* intrin.def: Use more descriptive name texts for generics
+	and specifics in cases where the names themselves are not
+	enough (e.g. IDATE, which has two forms).
+
+	Fix some intrinsic mappings:
+	* intrin.def (FFEINTRIN_specIDINT, FFEINTRIN_specAND,
+	FFEINTRIN_specDFLOAT, FFEINTRIN_specDREAL, FFEINTRIN_specOR,
+	FFEINTRIN_specXOR): Now have their own implementations,
+	instead of borrowing from others.

+	FFEINTRIN_specJINT, FFEINTRIN_specJIOR, FFEINTRIN_specJISHFT,
+	FFEINTRIN_specJISHFTC, FFEINTRIN_specJISIN, FFEINTRIN_specJMAX0,
+	FFEINTRIN_specJMAX1, FFEINTRIN_specJMIN0, FFEINTRIN_specJMIN1,
+	FFEINTRIN_specJMOD, FFEINTRIN_specJNINT, FFEINTRIN_specJNOT,):
+	Turn these implementations off, since it's not clear
+	just what types they expect in the context of portable Fortran.
+	(DFLOAT): Now in FVZ family, since f2c supports them
+
+	Support intrinsic inquiry functions (BIT_SIZE, LEN):
+	* intrin.c: Allow `i' in <arg_extra>.
+	* intrin.def (FFEINTRIN_impBIT_SIZE, FFEINTRIN_impLEN):
+	Mark args with `i'.

+
+	Complain about REAL(Z) and AIMAG(Z) (Z is DOUBLE COMPLEX):
+	* bad.def (FFEBAD_INTRINSIC_CMPAMBIG): New diagnostic.
+	* expr.c: Needed #include "intrin.h" anyway.
+	(ffeexpr_token_intrincheck_): New function handles delayed
+	diagnostic for "REAL(REAL(expr)" if next token isn't ")".
+	(ffeexpr_token_arguments_): Do most of the actual checking here.
+	* intrin.h, intrin.c (ffeintrin_fulfill_specific): New
+	argument, check_intrin, to tell caller that intrin is REAL(Z)
+	or AIMAG(Z).  All callers updated, mostly to pass NULL in
+	for this.
+	(ffeintrin_check_): Also has new arg check_intrin for same
+	purpose.  All callers updated the same way.
+	* intrin.def (FFEINTRIN_impAIMAG): Change return type
+	from "R0" to "RC", to accommodate f2c (and perhaps other
+	non-F90 F77 compilers).
+	* top.h, top.c: New option -fugly-complex.
+
+	New GNU intrinsics REALPART, IMAGPART, and COMPLEX:
+	* com.c (ffecom_expr_intrinsic_): Implement impCOMPLEX

+	* intrin.def: Add the intrinsics here.

+	* com.c (ffecom_expr_intrinsic_):
+	* intrin.def:
+
+	Delete intrinsic group `dcp', add `gnu', etc.:
+	* intrin.c (ffeintrin_state_family): FFEINTRIN_familyGNU

+	group.
+	Get rid of FFEINTRIN_familyF2Z, nobody needs it.
+	Move FFEINTRIN_specDCMPLX from DCP family to FVZ family,
+	as f2c has it.
+	Move FFEINTRIN_specDFLOAT from F2C family to FVZ family.
+	(FFEINTRIN_specZABS, FFEINTRIN_specZCOS, FFEINTRIN_specZEXP,
+	FFEINTRIN_specZLOG, FFEINTRIN_specZSIN, FFEINTRIN_specZSQRT):
+	Move these from F2Z family to F2C family.
+	* intrin.h (FFEINTRIN_familyF2Z, FFEINTRIN_familyDCP): Remove.
+	(FFEINTRIN_familyGNU): Add.
+	* top.h, top.c: Replace `dcp' with `gnu'.
+
+	* com.c (ffecom_expr_intrinsic_): Clean up by collecting
+	simple conversions into one nice, conceptual place.
+	Fix up some intrinsic subroutines (MVBITS, KILL, UMASK) to
+	properly push and pop call temps, to avoid wasting temp
+	registers.
+
+	* g77.c (doit): Toon says variables should be defined
+	before being referenced.  Spoilsport.
+
+	* intrin.c (ffeintrin_check_): Now Dave's worried about
+	warnings about uninitialized variables.  Okay, so for
+	basic return values 'g' and 's', they _were_
+	uninitialized -- is determinism really _that_ useful?
+
+	* intrin.def (FFEINTRIN_impFGETC): Fix STATUS argument
+	so that it is INTENT(OUT) instead of INTENT(IN).
+
+1997-02-21  Dave Love  <d.love@dl.ac.uk>
+
+	* intrin.def, com.c: Support Sun-type `short' and `long'
+	intrinsics.  Perhaps should also do Microcruft-style `int2'.
+
+Thu Feb 20 15:16:53 1997  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	* com.c (ffecom_expr_intrinsic_): Clean up indentation.

+	by obtaining it from processes it spawns.
+
+	* intdoc.c: Fix minor typo.
+
+	* intrin.def: Turn SECOND into generic that maps into
+	function and subroutine forms.
+
+	* intrin.def: Make FLOAT and SNGL into specific intrinsics.
+
+	* intrin.def, intrin.h: Change the way DEFGEN and DEFSPEC
+	macros work, to save on verbage.
+

+	after new doc subsystem.
+	* intdoc.c, intdoc.h: New doc subsystem code.
+	* intrin.h [FFEINTRIN_DOC]: When 1, don't pull in
+	stuff not needed by doc subsystem.
+
+	Improve on intrinsics mechanism to both be more
+	self-documenting and to catch more user errors:
+	* intrin.c (ffeintrin_check_): Recognize new arg-len
+	and arg-rank information, and check it.
+	Move goto and signal indicators to the basic type.
+	Permit reference to arbitrary argument number, not
+	just first argument (for BESJN and BESYN).
+	(ffeintrin_init_0): Check and accept new notations.
+	* intrin.c, intrin.def: Value in COL now identifies
+	arguments starting with number 0 being the first.
+
+	Some minor intrinsics cleanups (resulting from doc work):
+	* com.c (ffecom_expr_intrinsic_): Implement FLUSH
+	directly once again, handle its optional argument,
+	so it need not be a generic (awkward to handle in docs).
+	* intrin.def (BESJ0, BESJ1, BESJN, BESY0, BESY1, BESYN,
+	CHDIR, CHMOD, CTIME, DBESJ0, DBESJ1, DBESJN, DBESY0,
+	DBESY1, DBESYN, DDIM, ETIME, FGETC, FNUM, FPUTC, FSTAT,
+	GERROR, GETCWD, GETGID, GETLOG, GETPID, GETUID, GMTIME,
+	HOSTNM, IDATE, IERRNO, IIDINT, IRAND, ISATTY, ITIME, JIDINT,
+	LNBLNK, LSTAT, LTIME, MCLOCK, PERROR, SRAND, SYMLNK, TTYNAM,
+	UMASK): Change capitalization of initcaps (official) name
+	to be consistent with Burley's somewhat arbitrary rules.
+	(BESJN, BESYN): These have return arguments of same type
+	as their _second_ argument.
+	(FLUSH): Now a specific, not generic, intrinsic, with one
+	optional argument.
+	(FLUSH1): Eliminated.
+	Add arg-len and arg-rank info to several intrinsics.
+	(ITIME): Change argument type from REAL to INTEGER.
+
+Tue Feb 11 14:04:42 1997  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	* Make-lang.in (f771): Invocation of Makefile now done
+	with $(srcdir)=gcc to go along with $(VPATH)=gcc.
+	($(srcdir)/f/runtime/configure,
+	$(srcdir)/f/runtime/libU77/configure): Break these out
+	so spurious triggers of this rule don't happen (as when
+	configure.in is more recent than libU77/configure).
+	(f77.rebuilt): Distinguish source versus build files,
+	so this target can be invoked from build directory and
+	still work.
+	* Makefile.in: This now expects $(srcdir) to be the gcc
+	source directory, not gcc/f, to agree with $(VPATH).
+	Accordingly, $(INCLUDES) has been fixed, various cruft
+	removed, the removal of f771 has been fixed to remove
+	the _real_ f771 (not the one in gcc's parent directory),
+	and so on.
+
+	* lex.c: Part of ffelex_finish_statement_() now done
+	by new function ffelex_prepare_eos_(), so that, in one
+	popular case, the EOS can be prepared while the pointer
+	is at the end of the non-continued line instead of the
+	end of the line that marks no continuation.  This improves
+	the appearance of diagnostics substantially.
+
+Mon Feb 10 12:44:06 1997  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	* Make-lang.in: runtime Makefile's, and include/f2c.h,
+	also depend on f/runtime/configure and f/runtime/libU77/configure.
+
+	Fix various libU77 routines:
+	* com-rt.def (FFECOM_gfrtCTIME, FFECOM_gfrtMCLOCK,
+	FFECOM_gfrtTIME): These now use INTEGER*8 for time values,
+	for compatibility with systems like Alpha.
+	(FFECOM_gfrtSYSTEM_CLOCK, FFECOM_gfrtTTYNAM): Delete incorrect
+	trailing underscore in routine names.
+	* intrin.c, intrin.def: Support INTEGER*8 return values and
+	arguments ('4').  Change FFEINTRIN_impCTIME, FFEINTRIN_impMCLOCK,
+	and FFEINTRIN_impTIME accordingly.
+	(ffeintrin_is_intrinsic): Don't give caller a clue about
+	form of intrinsic -- shouldn't be needed at this point.
+
+	Cope with generic intrinsics that are subroutines and functions:
+	* com.c (ffecom_finish_symbol_transform_, ffecom_expr_transform_):
+	Don't transform an intrinsic that is not known to be a subroutine
+	or a function.  (Maybe someday have to avoid transforming
+	any intrinsic with an undecided or unknown implementation.)
+	* expr.c (ffeexpr_declare_unadorned_,
+	ffeexpr_declare_parenthesized_): Ok to invoke generic
+	intrinsic that has at least one subroutine form as a
+	subroutine.
+	Ok to pass intrinsic as actual arg if it has a known specific
+	intrinsic form that is valid as actual arg.
+	(ffeexpr_declare_parenthesized_): An unknown kind of
+	intrinsic has a paren_type chosen based on context.
+	(ffeexpr_token_arguments_): Build funcref/subrref based
+	on context, not on kind of procedure being called.
+	* intrin.h, intrin.c (ffeintrin_is_intrinsic): Undo changes of
+	Tue Feb  4 23:12:04 1997 by me, change all callers to leave
+	intrinsics as FFEINFO_kindNONE at this point.  (Some callers
+	also had unused variables deleted as a result.)
+
+	Enable all intrinsic groups (especially f90 and vxt):
+	* target.h (FFETARGET_defaultSTATE_DCP, FFETARGET_defaultSTATE_F2C,
+	FFETARGET_defaultSTATE_F90, FFETARGET_defaultSTATE_MIL,
+	FFETARGET_defaultSTATE_UNIX, FFETARGET_defaultSTATE_VXT):
+	Delete these macros, let top.c set them directly.
+	* top.c (ffeintrinsic_state_dcp_, ffe_intrinsic_state_f2c_,
+	ffe_intrinsic_state_f90_, ffe_intrinsic_state_mil_,
+	ffe_intrinsic_state_unix_, ffe_intrinsic_state_vxt_):
+	Enable all these directly.
+
+Sat Feb  8 03:21:50 1997  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	* g77.c: Incorporate recent changes to ../gcc.c.
+	For version magic (e.g. `g77 -v'), instead of compiling
+	/dev/null, write, compile, run, and then delete a small
+	program that prints the version numbers of the three
+	components of libf2c (libF77, libI77, and libU77),
+	so we get this info with bug reports.
+	Also, this change reduces the chances of accidentally
+	linking to an old (complex-alias-problem) libf2c.
+	Fix `-L' so the argument is expected in `-Larg'.
+
+	* com.h (FFECOM_f2cLONGINT): For INTEGER*8 support in f2c.h,
+	dynamically determine proper type here, instead of
+	assuming `long long int' is correct.
+
+Tue Feb  4 23:12:04 1997  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	Add libU77 library from Dave Love <d.love@dl.ac.uk>:
+	* Make-lang.in (f77-runtime): Depend on new Makefile.
+	(f/runtime/libU77/Makefile): New rule.
+	Also configure libU77.
+	($(srcdir)/f/runtime/configure: Use Makefile.in,
+	so configuration doesn't have to have happened.
+	(f77.mostlyclean, f77.clean, f77.distclean,
+	f77.maintainer-clean): Some fixups here, but more work
+	needed.
+	(RUNTIMESTAGESTUFF): Add libU77's config.status.
+	(LIBU77STAGESTUFF, f77.stage1, f77.stage2, f77.stage3,
+	f77.stage4): New macro, appropriate uses added.
+	* com-rt.def: Add libU77 procedures.
+	* com.c (ffecom_f2c_ptr_to_integer_type_node,
+	ffecom_f2c_ptr_to_real_type_node): New type nodes.
+	(FFECOM_rttypeCHARACTER_): New type of run-time function.
+	(ffecom_char_args_): Handle CHARACTER*n intrinsics
+	where n != 1 here, instead of in ffecom_expr_intrinsic_.
+	(ffecom_expr_intrinsic_): New code to handle new
+	intrinsics.
+	In particular, change how FFEINTRIN_impFLUSH is handled.
+	(ffecom_make_gfrt_): Handle new type of run-time function.
+	(ffecom_init_0): Initialize new type nodes.
+	* config-lang.in: New libU77 directory.
+	* intrin.h, intrin.c (ffeintrin_is_intrinsic): Handle
+	potential generic for subroutine _and_ function
+	specifics via two new arguments.  All callers changed.
+	Properly ignore deleted/disabled intrinsics in resolving
+	generics.
+	(ffeintrin_check_, ffeintrin_init_0): Handle CHARACTER intrinsics of (*)
+	length.
+	* intrin.def: Permission granted by FSF to place this in
+	public domain, which will allow it to serve as source
+	for both g77 program and its documentation.
+	Add libU77 intrinsics.
+	(FLUSH): Now a generic, not specific, intrinsic.
+	(DEFIMP): Now support return modifier for CHARACTER intrinsics.
+
+	* com-rt.def (FFECOM_gfrtDIM, FFECOM_gfrtERF,
+	FFECOM_gfrtERFC, FFECOM_gfrtEXP, FFECOM_gfrtSIGN,
+	FFECOM_gfrtSIN, FFECOM_gfrtSINH, FFECOM_gfrtTAN,
+	FFECOM_gfrtTANH, FFECOM_gfrtPOW_RI): Change "&r" to "&f".
+
+Sat Feb  1 12:15:09 1997  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	* Version 0.5.19.1 released.
+
+	* com.c (ffecom_expr_, ffecom_expr_intrinsic_,
+	ffecom_tree_divide_): FFECOM_gfrtPOW_ZI,
+	FFECOM_gfrtCONJG, FFECOM_gfrtDCONJG,
+	FFECOM_gfrtCCOS, FFECOM_gfrtCDCOS,
+	FFECOM_gfrtCLOG, FFECOM_gfrtCDLOG,
+	FFECOM_gfrtCSIN, FFECOM_gfrtCDSIN,
+	FFECOM_gfrtCSQRT, FFECOM_gfrtCDSQRT,
+	FFECOM_gfrtDIV_CC, FFECOM_gfrtDIV_ZZ: These all require
+	result to _not_ overlap one or more inputs.
+
+Sat Feb  1 00:25:55 1997  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	* com.c (ffecom_init_0): Do internal checks only if
+	-fset-g77-defaults not specified.
+
+	Fix %LOC(), LOC() to return sufficiently wide type:
+	* com.h, com.c (ffecom_pointer_kind_, ffecom_label_kind_,
+	ffecom_pointer_kind(), ffecom_label_kind()): New globals
+	and accessor macros hold kind for integer pointers on target
+	machine.
+	(ffecom_init_0): Determine narrowest INTEGER type that
+	can hold a pointer (usually INTEGER*4 or INTEGER*8),
+	store it in ffecom_pointer_kind_, etc.
+	* expr.c (ffeexpr_cb_end_loc_): Use right type for %LOC().
+	* intrin.c (ffeintrin_check_, ffeintrin_init_0): Support
+	new 'p' kind for type of intrinsic.
+	* intrin.def (FFEINTRIN_impLOC): Returns "Ip" instead of "I1",
+	so LOC() type is correct for target machine.
+
+	Support -fugly-assign:
+	* lang-options.h, top.h, top.c (ffe_decode_option):
+	Accept -fugly-assign and -fno-ugly-assign.
+	* com.c (ffecom_expr_): Handle -fugly-assign.
+	* expr.c (ffeexpr_finished_): Check right type for ASSIGN
+	contexts.
+
+Fri Jan 31 14:30:00 1997  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	Remove last vestiges of -fvxt-not-f90:
+	* stb.c (ffestb_R10012_, ffestb_R10014_, ffestb_V0201_):
+	top.c, top.h:
+
+Fri Jan 31 02:13:54 1997  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	* top.c (ffe_decode_option): Warn if -fugly is specified,
+	it'll go away soon.
+
+	* symbol.h: No need to #include "bad.h".
+
+	Reorganize features from -fvxt-not-f90 to -fvxt:
+	* lang-options.h, top.h, top.c:
+	Accept -fvxt and -fno-vxt, but not -fvxt-not-f90 or -ff90-not-vxt.
+	Warn if the latter two are used.
+	* expr.c (ffeexpr_nil_rhs_): Double-quote means octal constant.
+	(ffeexpr_token_rhs_): Double-quote means octal constant.
+	* target.h (FFETARGET_defaultIS_VXT_NOT_90): Delete macro

+
+	Make some -ff90 features the default:
+	* data.c (ffedata_value): DATA implies SAVE.

+
+	Fix up some more #error directives by quoting their text:
+	* bld.c (ffebld_constant_is_zero):

+
+Sat Jan 18 18:22:09 1997  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	* g77.c (lookup_option, main): Recognize `-Xlinker',
+	`-Wl,', `-l', `-L', `--library-directory', `-o',
+	`--output'.
+	(lookup_option): Don't depend on SWITCH_TAKES_ARG
+	being correct, it might or might not have `-x' in
+	it depending on host.
+	Return NULL argument if it would be an empty string.
+	(main): If no input files (by gcc.c's definition)
+	but `-o' or `--output' specified, produce diagnostic
+	to avoid overwriting output via gcc.
+	Recognize C++ `+e' options.
+	Treat -L as another non-magical option (like -B).
+	Don't append_arg `-x' twice.
+
+Fri Jan 10 23:36:00 1997  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	* top.c [BUILT_FOR_270] (ffe_decode_option): Make

+
+Fri Jan 10 07:42:27 1997  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	Enable inlining of previously-compiled program units:
+	* com.c (ffecom_do_entry_, ffecom_start_progunit_):
+	Register new public function in ffeglobal database.
+	(ffecom_sym_transform_): Any GLOBAL or potentially GLOBAL
+	symbol should be looked up in ffeglobal database and
+	that tree node used, if found.  That way, gcc knows
+	the references are to those earlier definitions, so it
+	can emit shorter branches/calls, inline, etc.
+	(ffecom_transform_common_): Minor change for clarity.
+	* expr.c (ffeexpr_sym-lhs_call_, ffeexpr_sym_lhs_extfunc_,
+	ffeexpr_sym_rhs_actualarg_, ffeexpr_paren_rhs_let_,

+	* ste.c (ffeste_R809): Produce a diagnostic for SELECT CASE
+	on CHARACTER type, instead of crashing.
+
+Thu Jan  9 00:52:45 1997  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	* stc.c (ffestc_order_entry_, ffestc_order_format_,
+	ffestc_R1226): Allow ENTRY and FORMAT before IMPLICIT
+	NONE, by having them transition only to state 1 instead
+	of state 2 (which is disallowed by IMPLICIT NONE).
+
+Mon Jan  6 22:44:53 1997  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	Fix AXP bug found by Rick Niles (961201-1.f):
+	* com.c (ffecom_init_0): Undo my 1996-05-14 change, as
+	it is incorrect and prevented easily finding this bug.
+	* target.h [__alpha__] (ffetargetReal1, ffetargetReal2):
+	Use int	instead of long.
+	(ffetarget_cvt_r1_to_rv_, ffetarget_cvt_rv_to_r1_,
+	ffetarget_cvt_r2_to_rv_, ffetarget_cvt_rv_to_r2_):
+	New functions that intercede for callers of
+	REAL_VALUE_(TO|UNTO)_TARGET_(SINGLE|DOUBLE).

+
+	* Make-lang.in (g77, g77-cross): Depend on both g77.c and

+	ffestc_R547_item_object): Pass new is_ugly_assumed flag.
+	* stt.c, stt.h (ffestt_dimlist_as_expr,
+	ffestt_dimlist_type): New is_ugly_assumed flag now
+	controls whether "1" is treated as "*".
+	Don't treat "2-1" or other collapsed constants as "*".
+
+Sat Jan  4 15:26:22 1997  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	* stb.c (ffestb_R10012_): Don't confirm on FORMAT(A,)
+	or even FORMAT(A,,B), as R1229 only warns about the
+	former currently, and this seems reasonable.
+
+	Improvements to diagnostics:
+	* sta.c (ffesta_second_): Don't add any ffestb parsers
+	unless they're specifically called for.
+	Set up ffesta_tokens[0] before calling ffestc_exec_transition,
+	else stale info might get used.
+	(ffesta_save_): Do a better job picking which parser to run
+	after running all parsers with no confirmed possibles.
+	(FFESTA_maxPOSSIBLES_): Decrease from 100 now that so few
+	possibles are ever on the list at a given time.
+	(struct _ffesta_possible): Add named attribute.
+	(ffesta_add_possible_exec_, ffesta_add_possible_nonexec_):
+	Make these into macros that call a single function that now

+	(ffesta_add_possible_unnamed_exec_,
+	ffeseta_add_possible_unnamed_nonexec_): New macros.
+	(ffesta_second_): Designate unnamed possibles as
+	appropriate.
+	* stb.c (ffestb_R1229, ffestb_R12291_): Use more general
+	diagnostic, so things like "POINTER (FOO, BAR)" are
+	diagnosed as unrecognized statements, not invalid statement
+	functions.
+	* stb.h, stb.c (ffestb_unimplemented): Remove function.
+
+1996-12-30  Dave Love  <d.love@dl.ac.uk>
+
+	* com.c: #include libU77/config.h
+	(ffecom_f2c_ptr_to_integer_type_node,
+ 	ffecom_f2c_ptr_to_integer_type_node): New variables.
+	(ffecom_init_0): Use them.
+	(ffecom_expr_intrinsic_): Many news cases for libU77 intrinsics.
+
+	* com-rt.def: New definitions for libU77.
+	* intrin.def: Likewise.  Also correct ftell arg spec.
+
+	* Makefile.in (f/runtime/libU77/config.h): New target for com.c
+ 	dependency.
+	* Make-lang.in (f771): Depend on f/runtime/Makefile for the above.
+
+Sat Dec 28 12:28:29 1996  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	* stt.c (ffestt_dimlist_type): 	Treat ([...,]1) in dimlist
+	as ([...,]*) if -fugly-assumed, so assumed-size array
+	detected early enough.
+
+Thu Dec 19 14:01:57 1996  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	* target.h (FFETARGET_REAL_VALUE_FROM_INT_): Conditionalize
+	definition on BUILT_FOR_280, not BUILT_WITH_280, since
+	the name of the macro was (properly) changed since 0.5.19.
+
+	Fix warnings/errors resulting from ffetargetOffset becoming
+	`long long int' instead of `unsigned long' as of 0.5.19,
+	while ffebitCount remains `unsigned long':
+	* bld.c (ffebld_constantarray_dump): Avoid warnings by
+	using loop var of appropriate type, and using casts.
+	* com.c (ffecom_expr_): Use right type for loop var.
+	(ffecom_sym_transform_, ffecom_transform_equiv_):
+	Cast to right type in assertions.
+	* data.c (ffedata_gather_, ffedata_value_): Cast to right
+	type in assertions and comparisons.

+
+Fri Dec  6 12:23:55 1996  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	* g77.c: Default to assuming "f77" is in $LANGUAGES, since
+	the LANGUAGE_F77 macro isn't defined by anyone anymore (but
+	might as well leave the no-f77 code in just in case).
+	* Make-lang.in (g77, g77-cross): Don't define LANGUAGE_F77
+	anymore.
+
+1996-12-06  Dave Love  <d.love@dl.ac.uk>
+

+
+Wed Dec  4 13:08:44 1996  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	* Make-lang.in (g77, g77-cross): No libs or lib dependencies
+	in case where "f77" is not in $LANGUAGES.
+
+	* lex.c (ffelex_image_char_, ffelex_file_fixed,
+	ffelex_file_free): Fixes to properly handle lines with
+	null character, and too-long lines as well.
+
+	* lex.c: Call ffebad_start_msg_lex instead of
+	ffebad_start_msg throughout.
+
+Sun Dec  1 21:19:55 1996  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	Fix-up for 1996-11-25 changes:
+	* com.c (ffecom_member_phase2_): Subtract out 0 offset for
+	elegance and consistency with EQUIVALENCE aggregates.
+	(ffecom_sym_transform_): Ditto for LOCAL/COMMON, and
+	ensure we get the same parent storage area.

+
+Wed Nov 27 13:55:57 1996  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	* proj.h: Quote the text of the #error message, to avoid
+	strange-looking diagnostics from non-gcc ANSI compilers.
+

+
+Mon Nov 25 20:13:45 1996  Craig Burley  <burley@gnu.ai.mit.edu>

+	case for SYMTER.
+	* com.c (ffecom_sym_transform_): For local EQUIVALENCE
+	member, subtract out aggregate offset (which is <= 0).
+
+Thu Nov 21 12:44:56 1996  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	Change type of ffetargetOffset from `unsigned long' to `long long':
+	* bld.c (ffebld_constantarray_dump): Change printf formats.
+	* storag.c (ffestorag_dump): Ditto.
+	* symbol.c (ffesymbol_report): Ditto.

+	* Make-lang.in: Define LANGUAGE_F77 to 1 only if `f77' is in
+	the $LANGUAGES macro for the build.
+	* g77.c: Compile to a (nearly) no-op program if LANGUAGE_F77
+	is not defined to 1.
+
+	Fixes to delay confirmation of READ, WRITE, and GOTO statements
+	so the corresponding assignments to same-named CHAR*(*) arrays
+	work:
+	* stb.c (ffestb_R90915_, ffestb_91014_): New functions.
+	(ffestb_goto3_, ffestb_goto5_): Move confirmation from 3 to 5
+	for the OPEN_PAREN case.
+	(ffestb_R9091_, ffestb_R9094_, ffestb_R90913_, ffestb_R90914_,
+	ffestb_R91012_, ffestb_R91013_): Use new functions, and confirm
+	except for the OPEN_PAREN case.
+
+	Fixes to not confirm declarations with an open paren where
+	an equal sign or other assignment-like token might be, so the
+	corresponding assignments to same-named CHAR*(*) arrays work:
+	(ffestb_decl_entsp_5_): Move assertion so we crash on that first,
+	if it turns out to be wrong, before the less-debuggable crash
+	on mistaken confirmation.
+	(ffestb_decl_entsp_6_, ffestb_decl_entsp_7_, ffestb_decl_entsp_8_):
+	Include OPEN_PAREN in list of assignment-only tokens.
+
+	Fix more diagnosed-crash bugs:
+	* stu.c (ffestu_sym_end_transition): ANY-ize an adjustable array
+	with bad dimension expressions even if still stateUNCERTAIN.
+	(ffestu_symter_end_transition_, ffestu_symter_exec_transition_):
+	Return TRUE for opANY as well.
+	For code elegance, move opSYMTER case into first switch.
+
+1996-11-17  Dave Love  <d.love@dl.ac.uk>
+
+	* lex.c: Fix last change.
+
+1996-11-14  Dave Love  <d.love@dl.ac.uk>
+
+	* Make-lang.in, config-lang.in: Remove the (broken) libU77 stuff,
+	pending 0.5.20.
+
+Thu Nov 14 15:40:59 1996  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	* bad.def (FFEBAD_UNIMPL_STMT): Explain that invalid

+
+1996-11-12  Dave Love  <d.love@dl.ac.uk>
+
+        * lex.c: Declare dwarfout routines.
+
+        * config-lang.in: Sink grep o/p.
+
+Mon Nov 11 14:21:13 1996  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	* g77.c (main): Might as well print version number
+	for --verbose as well.
+
+Thu Nov  7 18:41:41 1996  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	* expr.c, lang-options.h, target.h, top.c, top.h: Split out
+	remaining -fugly stuff into -fugly-logint and -fugly-comma,
+	leaving -fugly as simply a `macro' that expands into other
+	options, and eliminate defaults for some of the ugly stuff
+	in target.h.
+
+	* Make-lang.in (gcc-cross): Compile zzz.c, not version.o (!),
+	in to get version info for this target.
+
+	* config-lang.in: Test for GBE patch application based
+	on whether 2.6.x or 2.7.x GBE is detected.
+
+Wed Nov  6 14:19:45 1996  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	* Make-lang.in (g77): Compile zzz.c in to get version info.
+	* g77.c: Add support for --help and --version.
+
+	* g77.c (lookup_option): Short-circuit long-winded tests
+	when second char is not hyphen, just to save a spot of time.
+
+Sat Nov  2 13:50:31 1996  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	* intrin.def: Add FTELL and FSEEK intrinsics, plus new
+	`g' codes for alternate-return (GOTO) arguments.
+	* intrin.c (ffeintrin_check_): Support `g' codes.
+	* com-rt.def: Add ftell_() and fseek_() to database.
+	* com.c (ffecom_expr_intrinsic_): Ditto.  Also, let each
+	subroutine intrinsic decide for itself what to do with
+	tree_type, the default being NULL_TREE once again (so
+	ffecom_call_ doesn't think it's supposed to cast the
+	function call to the type in the fall-through case).
+
+	* ste.c (ffeste_R909_finish): Don't special-case list-directed
+	I/O, now that libf2c can return non-zero status codes.
+	(ffeste_R910_finish): Ditto.
+	(ffeste_io_call_): Simplify logic.
+	(ffeste_io_impdo_):
+	(ffeste_subr_beru_):
+	(ffeste_R904):

+	(ffeste_R910_item):
+	(ffeste_R910_finish):
+	(ffeste_R911_start):
+	(ffeste_R923A): Ditto all the above.
+
+Thu Oct 31 20:56:28 1996  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	* config-lang.in, Make-lang.in: Rename flag file
+	build-u77 to build-libu77, for consistency with
+	install-libf2c and such.
+
+	* config-lang.in: Don't complain about failure to patch
+	if pre-2.7.0 gcc is involved (since our patch for that
+	doesn't add support for tooning).
+
+Sat Oct 26 05:56:51 1996  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	* bad.def (FFEBAD_TYPELESS_TOO_LARGE): Remove this
+	unused and redundant diagnostic.
+
+Sat Oct 26 00:45:42 1996  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	* target.c (ffetarget_integerhex): Fix dumb bug.
+
+1996-10-20  Dave Love  <d.love@dl.ac.uk>
+
+	* gbe/2.7.2.1.diff: New file.
+
+	* Makefile.in (F771_LDFLAGS): Add -bbigtoc for AIX4.1 up, suggested by
+	endo@material.tohoku.ac.jp [among others!].
+
+Sat Oct 19 03:11:14 1996  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	* bad.def, bld.c, bld.h, expr.c, lang-options.h, target.c,
+	target.h, top.c, top.h (ffebld_constant_new_integerbinary,
+	ffebld_constant_new_integerhex, ffebld_constant_new_integeroctal,
+	ffeexpr_token_name_apos_name_, ffetarget_integerbinary,
+	ffetarget_integerhex, ffetarget_integeroctal): Support
+	new -fno-typeless-boz option with new functions, mods to
+	existing octal-handling functions, new macros, new error
+	messages, and so on.
+
+	* com.c, lang-options.h, top.c, top.h (ffecom_notify_primary_entry):
+	Print program unit name on stderr if -fno-silent (new option).
+
+	* lang-options.h, top.c, top.h, stt.c (ffestt_dimlist_as_expr):
+	Treat ([...,]1) in dimlist as ([...,]*) if -fugly-assumed
+	(new option).
+
+	* lang-options.h: Comment out options duplicated in gcc/toplev.c,
+	because, somehow, having them commented in and building on my
+	DEC Alpha results in a cc1 that always segfaults, and gdb that
+	also segfaults whenever it debugs it up to init_lex() calling
+	xmalloc() or so.
+
+Thu Oct 17 00:39:27 1996  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	* stb.c (ffestb_R10013_): Don't change meaning of .sign until
+	after previous meaning/value used to set sign of value
+	(960507-1.f).
+
+Sun Oct 13 22:15:23 1996  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	* top.c (ffe_decode_option): Don't set back-end flags
+	that are nonexistent prior to gcc 2.7.0.
+
+Sun Oct 13 12:48:45 1996  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	* com.c (convert): Don't convert emulated complex expr to
+	real (via REALPART_EXPR) if the target type is (emulated)
+	complex.
+
+Wed Oct  2 21:57:12 1996  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	* com.c (ffecom_debug_kludge_): Set DECL_IN_SYSTEM_HEADER so
+	-Wunused doesn't complain about these manufactured decls.
+	(ffecom_expr_): Ditto, for original (non-ASSIGN'ed) variable.
+	(ffecom_transform_equiv_): Clear DECL_IGNORED_P for aggregate
+	area so it shows up as a debug-accessible symbol.
+	(pushdecl): Default for "invented" identifiers (a g77-specific
+	concept for now) is that they are artificial, in system header,
+	ignored for debugging purposes, used, and (for types) suppressed.
+	This ought to be overkill.
+
+Fri Sep 27 23:13:07 1996  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	* ste.c (ffeste_begin_iterdo_, ffeste_end_iterdo_): Support
+	one-trip DO loops (F66-style).
+	* lang-options.h, top.c, top.h (-fonetrip): New option.
+
+Thu Sep 26 00:18:40 1996  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	* com.c (ffecom_debug_kludge_): New function.
+	(ffecom_sym_transform_): Use new function for COMMON and EQUIVALENCE
+	members.
+
+	* lang-options.h, top.c, top.h (-fno-debug-kludge):
+	New option.
+
+1996-09-24  Dave Love  <d.love@dl.ac.uk>
+
+	* Make-lang.in (include/f2c.h):
+	Remove dependencies on xmake_file and tmake_file.
+	They expand inconsistently in 2.8 c.f. 2.7; $(GCC_PARTS) depends on
+	them anyhow.
+
+1996-09-22  Dave Love  <d.love@dl.ac.uk>
+
+	* config-lang.in: Add --enable-libu77 option handling.
+
+	* Make-lang.in:
+	Conditionally add --enable-libu77 when running runtime configure.
+	Define LIBU77STAGESTUFF and use it in relevant rules.
+
+1996-08-21  Dave Love  <d.love@dl.ac.uk>
+
+	* Make-lang.in (f77-runtime):
+	`stmp-hdrs' should have been `stmp-headers'.
+
+1996-08-20  Dave Love  <d.love@dl.ac.uk>
+
+	* Make-lang.in (f77-runtime):
+	Depend on stmp-hdrs, not stmp-int-hdrs, since libF77
+	needs float.h.
+
+Sat Jun 22 18:17:11 1996  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	* com.c (ffecom_tree_divide_): Fix RECORD_TYPE case to
+	look at type of first field, properly, to determine
+	whether to call c_div or z_div.
+
+Tue Jun  4 04:27:18 1996  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	* com.c (ffecom_build_complex_constant_): Explicitly specify
+	TREE_PURPOSE.
+	(ffecom_expr_): Fix thinko.
+	(ffecom_2): For COMPLEX_EXPR, explicitly specify TREE_PURPOSE.
+
+Mon May 27 16:23:43 1996  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	Changes to optionally avoid gcc's back-end complex support:
+	* com.c (ffecom_stabilize_aggregate_): New function.
+	(ffecom_convert_to_complex_): New function.
+	(ffecom_make_complex_type_): New function.
+	(ffecom_build_complex_constant_): New function.
+	(ffecom_expr_): For opCONVERT of non-COMPLEX to COMPLEX,
+	don't bother explicitly converting to the subtype first,
+	because gcc does that anyway, and more code would have
+	to be added to find the subtype for the emulated-complex
+	case.
+	(ffecom_f2c_make_type_): Use ffecom_make_complex_type_
+	instead of make_node etc. to make a complex type.
+	(ffecom_1, ffecom_2): Translate operations on COMPLEX operands
+	to appropriate operations when emulating complex.
+	(ffecom_constantunion): Use ffecom_build_complex_constant_
+	instead of build_complex to build a complex constant.
+	(ffecom_init_0): Change point at which types are laid out
+	for improved consistency.
+	Use ffecom_make_complex_type_ instead of make_node etc.
+	to make a complex type.
+	Always calculate storage sizes from TYPE_SIZE, never TYPE_PRECISION.
+	(convert): Use e, not expr, since we've copied into that anyway.
+	For RECORD_TYPE cases, do emulated-complex conversions.
+	(ffecom_f2c_set_lio_code_): Always calculate storage sizes
+	from TYPE_SIZE, never TYPE_PRECISION.
+	(ffecom_tree_divide_): Allow RECORD_TYPE to also be handled
+	by run-time library.
+	(ffecom_expr_intrinsic_): Handle possible RECORD_TYPE as argument
+	to AIMAG intrinsic.
+
+	* top.h, top.c, lang-options.h: Support new -f(no-)emulate-complex option.
+
+	* com.c (ffecom_sym_transform_): Clarify and fix typos in comments.
+
+Mon May 20 02:06:27 1996  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	* target.h: Use new REAL_VALUE_UNTO_TARGET_* macros instead
+	of REAL_VALUE_FROM_TARGET_DOUBLE and _SINGLE.
+	Explicitly use long instead of HOST_WIDE_INT for emulation
+	of ffetargetReal1 and ffetargetReal2.
+
+1996-05-20  Dave Love  <d.love@dl.ac.uk>
+
+	* config-lang.in:
+	Test for patch being applied with flag_move_all_movables in toplev.c.
+
+	* install.texi (Patching GNU Fortran):
+	Mention overriding X_CFLAGS rather than
+	editing proj.h on SunOS4.
+
+	* Make-lang.in (F77_FLAGS_TO_PASS):
+	Add X_CFLAGS (convenient for SunOS4 kluge, in
+	particular).
+	(f77.{,mostly,dist}clean): Reorder things, in particular not to delete
+	Makefiles too early.
+
+	* g77.c (DEFAULT_SWITCH_TAKES_ARG): Define a la gcc.c in the
+	current GCC snapshot.
+
+Tue May 14 00:24:07 1996  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	Changes for DEC Alpha AXP support:
+	* com.c (ffecom_init_0): REAL_ARITHMETIC means internal
+	REAL/DOUBLE PRECISION might well have a different size
+	than the compiled type, so don't crash if this is the
+	case.
+	* target.h: Use `int' for ffetargetInteger1,
+	ffetargetLogical1, and magical tests.  Set _f format
+	strings accordingly.
+
+Tue Apr 16 14:08:28 1996  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	* top.c (ffe_decode_option): -Wall no longer implies
+	-Wsurprising.
+
+Sat Apr 13 14:50:06 1996  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	* com.c (ffecom_char_args_): If item is error_mark_node,
+	set *length that way, too.
+
+	* com.c (ffecom_expr_power_integer_): If either operand
+	is error_mark_node, return that.
+
+	* com.c (ffecom_intrinsic_len_): If item is error_mark_node,
+	return that for length.
+
+	* expr.c (ffeexpr_declare_unadorned_,
+	ffeexpr_declare_parenthesized_): Instead of crashing
+	on unexpected contexts, produce a diagnostic.
+
+	* intrin.c (ffeintrin_check_), intrin.def (impSIGNAL):
+	Allow procedure as second arg to SIGNAL intrinsic.
+
+	* stu.c (ffestu_symter_end_transition_): New function.
+	(ffestu_symter_exec_transition_): Return bool arg.
+	Always transition symbol (don't inhibit when !whereNONE).
+	(ffestu_sym_end_transition): If DUMMY/LOCAL arg has any
+	opANY exprs in its dimlist, diagnose it so it doesn't
+	make it through to later stages that try to deal with
+	dimlist stuff.
+	(ffestu_sym_exec_transition): If sym has any opANY exprs
+	in its dimlist, diagnose it so it becomes opANY itself.
+
+	* symbol.c (ffesymbol_error): If token arg is NULL,
+	just ANY-ize the symbol -- don't produce diagnostic.
+
+Mon Apr  1 10:14:02 1996  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	* Version 0.5.18 released.
+
+Mon Mar 25 20:52:24 1996  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	* com.c (ffecom_expr_power_integer_): Don't generate code
+	that compares COMPLEX (or, as it happens, REAL) via "LT_EXPR",
+	since the back end crashes on that.  (This code would never
+	be executed anyway, but the test that avoids it has now been
+	translated to control whether the code gets generated at all.)
+	Fixes 960323-3.f.
+
+	* com.c (ffecom_type_localvar_): Handle variable-sized
+	dimension bounds expressions here, so they get calculated
+	and saved on procedure entry.  Fixes 960323-4.f.
+
+	* com.c (ffecom_notify_init_symbol): Symbol has no init
+	info at all if only zeros have been used to initialize it.
+	Fixes 960324-0.f.
+
+	* expr.c, expr.h (ffeexpr_type_combine): Renamed from
+	ffeexpr_type_combine_ and now a public procedure; last arg now
+	a token, instead of an internal structure used to extract a token.
+	Now allows the outputs to be aliased with the inputs.
+	Now allows a NULL token to mean "don't report error".
+	(ffeexpr_reduced_bool2_, ffeexpr_reduced_eqop2_,
+	ffeexpr_reduced_math2_, ffeexpr_reduced_power_,
+	ffeexpr_reduced_relop2_): Handle new calling sequence for
+	ffeexpr_type_combine.
+	* (ffeexpr_convert): Don't put an opCONVERT node
+	in just because the size is unknown; all downstream code
+	should be able to deal without it being there anyway, and
+	getting rid of it allows new intrinsic code to more easily
+	combine types and such without generating bad code.
+	* info.c, info.h (ffeinfo_kindtype_max): Rewrite to do
+	proper comparison of size of types, not just comparison
+	of their internal kind numbers (so I2.eq.I1 doesn't promote
+	I1 to I2, rather the other way around).
+	* intrin.c (ffeintrin_check_): Combine types of arguments
+	in COL a la expression handling, for greater flexibility
+	and permissiveness (though, someday, -fpedantic should
+	report use of this kind of thing).
+	Make sure Hollerith/typeless where CHARACTER expected is
+	rejected.  This all fixes 960323-2.f.
+
+	* ste.c (ffeste_begin_iterdo_): Fix some more type conversions
+	so INTEGER*2-laden DO loops don't crash at compile time on
+	certain machines.  Believed to fix 960323-1.f.
+
+	* stu.c (ffestu_sym_end_transition): Certainly reject
+	whereDUMMY not in any dummy list, whether stateUNCERTAIN
+	or stateUNDERSTOOD.  Fixes 960323-0.f.
+
+Tue Mar 19 13:12:40 1996  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	* data.c (ffedata_value): Fix crash on opANY, and simplify
+	the code at the same time.
+
+	* Make-lang.in (f77-runtime): Also depends on lib[FI]77/Makefile...
+	(include/f2c.h...): ...which in turn depend on */Makefile.in.
+	(f77.rebuilt): Rebuild runtime stuff too.
+
+	* intrin.c (ffeintrin_check_): Accommodate TYPELESS/HOLLERITH
+	types, convert args as necessary, etc.
+
+	* expr.c (ffeexpr_convert): Fix test for TYPELESS/HOLLERITH
+	to obey the docs; crash if no source token when error.
+	(ffeexpr_collapse_convert): Crash if no token when error.
+
+Mon Mar 18 15:51:30 1996  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	* com.c (ffecom_init_zero_): Renamed from
+	ffecom_init_local_zero_; now handles top-level
+	(COMMON) initializations too.
+
+	* bld.c (ffebld_constant_is_zero):
+	* com.c (ffecom_symbol_transform_, ffecom_sym_transform_assign_,
+	ffecom_transform_common_, ffecom_transform_equiv_):
+	* data.c:
+	* equiv.c:
+	* equiv.h:
+	* lang-options.h:
+	* stc.c:
+	* storag.c:
+	* storag.h:
+	* symbol.c:
+	* symbol.h:
+	* target.c:
+	* target.h:
+	* top.c:
+	* top.h: All of this is mostly housekeeping-type changes
+	to support -f(no-)zeros, i.e. not always stuff zero
+	values into the initializer fields of symbol/storage objects,
+	but still track that they have been given initial values.
+
+	* bad.def: Fix wording for DATA-related diagnostics.
+
+	* com.c (ffecom_sym_transform_assign_): Don't check
+	any EQUIVALENCE stuff for local ASSIGN, the check was
+	bad (crashing), and it's not necessary, anyway.
+
+	* com.c (ffecom_expr_intrinsic_): For MAX and MIN,
+	ignore null arguments as far arg[123], and fix handling
+	of ANY arguments.  (New intrinsic support now allows
+	spurious trailing null arguments.)
+
+	* com.c (ffecom_init_0): Add HOLLERITH (unsigned)
+	equivalents for INTEGER*2, *4, and *8, so shift intrinsics
+	and other things that need unsigned versions of signed
+	types work.
+
+Sat Mar 16 12:11:40 1996  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	* storag.c (ffestorag_exec_layout): Treat adjustable
+	local array like dummy -- don't create storage object.
+	* com.c (ffecom_sym_transform_): Allow for NULL storage
+	object in LOCAL case (adjustable array).
+
+Fri Mar 15 13:09:41 1996  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	* com.c (ffecom_sym_transform_): Allow local symbols
+	with nonconstant sizes (adjustable local arrays).
+	(ffecom_type_localvar_): Allow dimensions with nonconstant
+	component (adjustable local arrays).
+	* expr.c: Various minor changes to handle adjustable
+	local arrays (a new case of stateUNCERTAIN).
+	* stu.c (ffestu_sym_end_transition,
+	ffestu_sym_exec_transition): Ditto.
+	* symbol.def: Update docs to reflect these changes.
+
+	* com.c (ffecom_expr_): Reduce space/time needed for
+	opACCTER case by handling it here instead of converting
+	it to opARRTER earlier on.
+	(ffecom_notify_init_storage): Don't convert ACCTER to ARRTER.
+	(ffecom_notify_init_symbol): Ditto.
+
+	* com.c (ffecom_init_0): Crash and burn if any of the types'
+	sizes, according to the GBE, disagrees with the sizes of
+	the FFE's internal implementation.  This might catch
+	Alpha/SGI bugs earlier.
+
+Fri Mar 15 01:09:41 1996  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	* com-rt.def, com.c, com.h: Changes for rewrite of intrinsic
+	handling.
+	* com.c (ffecom_arglist_expr_): New function.
+	(ffecom_widest_expr_type_): New function.
+	(ffecom_expr_intrinsic_): Reorganize, some rewriting.
+	(ffecom_f2c_make_type_): Layout complex types.
+	(ffecom_gfrt_args_): New function.
+	(ffecom_list_expr): Trivial change for consistency.
+
+	* expr.c (ffeexpr_token_name_rhs_): Go back to getting
+	type from specific, not implementation, info.
+	(ffeexpr_token_funsubstr_): Set intrinsic implementation too!
+	* intrin.c: Major rewrite of most portions.
+	* intrin.def: Major rearchitecting of tables.
+	* intrin.h (ffeintrin_basictype, ffeintrin_kindtype):
+	Now (once again) take ffeintrinSpec as arg, not ffeintrinImp;
+	for now, these return NONE, since they're not really needed
+	and adding the necessary info to the tables is not trivial.

+
+	* Make-lang.in (stmp-int-hdrs): Use --no-validate when
+	generating the f77.rebuilt files (BUGS, INSTALL, NEWS)

+	If ffecom_expr_power_integer_ returns NULL_TREE, just do
+	the usual work.
+	(ffecom_make_gfrt_): Handle new type.
+	(ffecom_expr_power_integer_): Let caller do the work if in
+	dummy-transforming case, since
+	caller now knows about INTEGER*8 and such, by returning
+	NULL_TREE.
+	* expr.c (ffeexpr_reduced_power_): Complain about non-INTEGER
+	raised to INTEGER4 (INTEGER*8) power.
+
+	* target.c (ffetarget_power_integerdefault_integerdefault):
+	Fix any**negative.
+	* com.c (ffecom_expr_power_integer_): Fix (-1)**(-8) and similar

+
+	* expr.c (ffeexpr_finished_): For DO loops, allow
+	any INTEGER type; convert LOGICAL (assuming -fugly)
+	to corresponding INTEGER type instead of always default
+	INTEGER; let later phases do conversion of DO start,
+	end, incr vars for implied-DO; change checks for non-integral
+	DO vars to be -Wsurprising warnings.
+	* ste.c (ffeste_io_impdo_): Convert start, end, and incr
+	to type of DO variable.
+
+	* com.c (ffecom_init_0): Add new types for [IL][234],

+
+	* expr.c (ffeexpr_declare_unadorned_,
+	ffeexpr_declare_parenthesized_): Break out handling of
+	contextDATAIMPDO[INDEX,CTRL] so it's independent of symbol state.
+	Don't exec-transition these here (let ffeexpr_sym_impdoitem_

+
+Tue Dec  5 06:48:26 1995  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	* stc.c (ffestc_promote_sfdummy_): Allow whereNONE parent
+	symbol, since it is not necessarily known whether it will

+
+Mon Dec  4 03:46:55 1995  Craig Burley  <burley@gnu.ai.mit.edu>
+

+	for "no checking" to improve compile times.
+
+	* malloc.c (malloc_pool_kill): Fix bug that could prevent

+	count to 1).
+
+	* proj.h, *.c (dmpout): Replace all occurrences of `stdout'
+	and some of `stderr' with `dmpout', so where to dump debugging
+	output can be easily controlled during build; add default
+	for `dmpout' of `stderr' to proj.h.
+
+Sun Dec  3 00:56:29 1995  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	* com.c (ffecom_return_expr): Eliminate attempt at warning
+	about unset return values, since the back end does this better,
+	with better wording, and is not triggered by clearly working
+	(but spaghetti) code as easily as this test.
+
+Sat Dec  2 08:28:56 1995  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	* target.c (ffetarget_power_*_integerdefault): Raising 0 to
+	integer constant power should not be an error condition;
+	if so, other code should catch 0 to any power, etc.
+
+	* bad.def (FFEBAD_BAD_POWER): 0**integer now a warning instead

+
+Fri Dec  1 00:12:03 1995  Craig Burley  (burley@gnu.ai.mit.edu)
+
+	* bad.def: Clarify diagnostic regarding complex constant elements.

+
+Sat Nov 18 19:37:22 1995  Craig Burley  (burley@gnu.ai.mit.edu)
+
+	* Version 0.5.17 released.
+
+Fri Nov 17 14:27:24 1995  Craig Burley  (burley@gnu.ai.mit.edu)
+
+	* Make-lang.in: Fix typo in comment.
+
+	* Makefile.in (f/fini.o, f/proj-h.o): Don't use `$<' since
+	not all makes support it (e.g. NeXT make), use explicit
+	source name instead (with $(srcdir) and munging).
+	(ASSERT_H): assert.h lives in source dir, not build dir.
+
+Thu Nov 16 12:47:50 1995  Craig Burley  (burley@gnu.ai.mit.edu)
+
+	* com.c (ffecom_init_0): Fix dumb bug in code to produce
+	warning message about non-32-bit-systems.
+
+	* stc.c (ffestc_R501_item): Parenthesize test to make

+
+Thu Nov 16 03:43:33 1995  Craig Burley  (burley@gnu.ai.mit.edu)
+
+	* g77.c: Upgrade to 2.7.0's gcc.c.

+
+Fri Nov 10 19:16:05 1995  Craig Burley  (burley@gnu.ai.mit.edu)
+
+	* ste.c (ffeste_begin_iterdo_): Add Toon's change to
+	make loops faster on some machines (implement termination
+	condition as "--i >= 0" instead of "i-- > 0").
+
+Thu Nov  2 03:58:17 1995  Craig Burley  (burley@gnu.ai.mit.edu)
+
+	* Make-lang.in: Remove unnecessary $(exeext) a la cp/Make-lang.in.
+
+	* com.c (ffecom_expr_): Restore old strategy for assignp variant
+	of opSYMTER case...always return the ASSIGN version of var.
+	That way, `-O -Wuninitialized' will catch "I=3;GOTO I;END"
+	(though the diagnostic will refer to `__g77_ASSIGN_i').
+
+	* com.c (ffecom_expr_power_integer_): For constant rhs case,
+	wrap every new eval of lhs in save_expr() so it is clear to
+	back end that MULT_EXPR(lhs,lhs) has identical operands,
+	otherwise for an rhs like 32767 it generates around 65K pseudo
+	registers, with which stupid_life_analysis cannot cope
+	(due to reg_renumber in regs.h being `short *' instead of
+	`int *').
+
+	* com.c (ffecom_expr_): Speed up implementation of LOGICAL
+	versions of opNOT, opAND, opOR, opXOR/opNEQV, and opEQV by
+	assuming the values actually are kosher LOGICAL bit patterns.
+	Also simplify code that implements some of the INTEGER versions
+	of these.
+
+	* com.c (skip_redundant_dir_prefix, read_name_map,
+	ffecom_open_include_, signed_type, unsigned_type): Fold in
+	changes to cccp.c made from 2.7.0 through ss-950826.
+
+	* equiv.c (ffeequiv_layout_local_): Kill the equiv list
+	if no syms in list.
+
+	* expr.c (ffeexpr_reduced_eqop2_): Issue specific diagnostic
+	regarding usage of .EQV./.NEQV. in preference to .EQ./.NE..
+
+	* intrin.c: Add ERF and ERFC as generic intrinsics.
+	intrin.def: Same.
+
+	* sta.c (ffesta_save_, ffesta_second_): Whoever calls
+	ffestd_exec_begin must also set ffesta_seen_first_exec = TRUE,
+	and anytime stc sees an exec transition, it must do both.
+	stc.c (ffestc_eof): Same.
+
+	* stc.c (ffestc_promote_sfdummy_): If failed implicit typing
+	or CHARACTER*(*) arg, after calling ffesymbol_error, don't
+	reset info to ENTITY/DUMMY, because ffecom_sym_transform_
+	doesn't expect such a thing with ANY/ANY type.
+
+	* target.h (*logical*): Change some of these so they parallel
+	changes in com.c, e.g. for _eqv_, use (l)==(r) instead of
+	!!(l)==!!(r), to get a more faithful result.
+
+Fri Oct 27 07:06:59 1995  Craig Burley  (burley@gnu.ai.mit.edu)
+
+	* com.c (ffecom_sym_transform_): Simplify code for local
+	EQUIVALENCE case.
+
+	* expr.c (ffeexpr_exprstack_push_unary_): Warn about two
+	successive operators.
+	(ffeexpr_exprstack_push_binary_): Warn about "surprising"
+	operator precedence, as in "-2**2".
+
+	* lang-options.h: Add -W(no-)surprising options.
+
+	* parse.c (yyparse): Don't reset -fpedantic if not -pedantic.
+
+	* top.c (ffe_decode_option): Support new -Wsurprising option.
+	* top.h: Ditto.
+
+Mon Oct 23 09:14:15 1995  Craig Burley  (burley@gnu.ai.mit.edu)
+
+	* com.c (ffecom_finish_symbol_transform_): Don't transform
+	NONE/NONE (CHARACTER*(*)) vars, as these don't mean anything
+	in debugging terms, and can't be turned into anything
+	in the back end (so ffecom_sym_transform_ crashes on them).
+
+	* com.c (ffecom_expr_): Change strategy for assignp variant
+	of opSYMTER case...always return the original var unless
+	it is not wide enough.
+
+	* ste.c (ffeste_io_cilist_): Clarify diagnostic for ASSIGN
+	involving too-narrow variable.  This shouldn't happen, though.
+	(ffeste_io_icilist_): Ditto.
+	(ffeste_R838): Ditto.
+	(ffeste_R839): Ditto.
+
+Thu Oct 19 03:21:20 1995  Craig Burley  (burley@gnu.ai.mit.edu)
+
+	* com.c (ffecom_sym_transform_assign_): Set TREE_STATIC
+	using the same decision-making process as used for their twin
+	variables, so ASSIGN can last across RETURN/CALL as appropriate.
+
+Fri Sep 22 20:21:18 1995  Craig Burley  (burley@gnu.ai.mit.edu)
+
+	* Makefile.in: fini is a host program, so it needs a host-compiled
+	version of proj.o, named proj-h.o.  f/fini, f/fini.o, and
+	f/proj-h.o targets updated accordingly.
+
+	* com.c (__eprintf): New function.
+
+Wed Sep 20 02:26:36 1995  Craig Burley  (burley@gnu.ai.mit.edu)
+
+	* lang-options.h: Add omitted -funix-intrinsics-* options.
+
+	* malloc.c (malloc_find_inpool_): Check for infinite
+	loop, crash if detected (user reports encountering
+	them in some large programs, this might help track
+	down the bugs).
+
+Thu Sep  7 13:00:32 1995  Craig Burley  (burley@gnu.ai.mit.edu)
+
+	* com.c (lang_print_error_function): Don't dereference null
+	pointer when outside any program unit.
+	(ffecom_let_char_, ffecom_arg_ptr_to_expr): If catlist
+	item or length ever error_mark_node, don't continue processing,
+	since back-end functions like build_pointer_type crash on
+	error_mark_node's (due to pushing bad obstacks, etc.).
+
+Wed Aug 30 15:58:35 1995  Craig Burley  (burley@gnu.ai.mit.edu)
+
+	* Version 0.5.16 released.
+
+Mon Aug 28 12:24:20 1995  Craig Burley  (burley@gnu.ai.mit.edu)
+
+	* bad.c (ffebad_finish): Fix botched message when no places
+	are printed (due to unknown line info, etc.).
+
+	* std.c (ffestd_subr_labels_): Do a better job finding
+	line info in the case of typeANY and diagnostics.
+
+Fri Aug 25 15:19:29 1995  Craig Burley  (burley@gnu.ai.mit.edu)
+
+	* com.c (DECL_ARTIFICIAL): Surround all references to this
+	macro with #if !BUILT_FOR_270 and #endif.
+	(init_lex): Surround print_error_function decl with
+	#if !BUILT_FOR_270 and #endif.
+	(lang_init): Call new ffelex_hash_kludge function to solve
+	problem with preprocessed files that have INCLUDE statements.
+
+	* lex.c (ffelex_getc_): New function.
+	(ffelex_cfelex_): Use ffelex_getc_ instead of getc in any
+	paths of code that can be affected by ffelex_hash_kludge.
+	Don't make an EOF token for unrecognized token; set token
+	to NULL instead, to avoid problems when not initialized.
+	(ffelex_hash_): Use ffelex_getc_ instead of getc in any
+	paths of code that can be affected by ffelex_hash_kludge.
+	Test token returned by ffelex_cfelex_ for NULL, meaning
+	unrecognized token.

+	Don't do ffewhere stuff or kill any tokens if in
+	ffelex_hash_kludge.
+	(ffelex_file_fixed, ffelex_file_free): Use ffelex_getc_

+
+Wed Aug 23 15:17:40 1995  Craig Burley  (burley@gnu.ai.mit.edu)
+
+	* com.c: Implement -f(no-)underscoring options by always
+	compiling in code to do it, and having that code inhibit
+	itself when -fno-underscoring is in effect.  This option
+	overrides -f(no-)f2c for this purpose; -f(no-)f2c returns
+	to it's <=0.5.15 behavior of affecting only how code
+	is generated, not how/whether names are mangled.
+
+	* target.h: Redo specification of appending underscores so
+	the macros are named "_default" instead of "_is" and the
+	two-underscore macro defaults to 1.
+
+	* top.c, top.h (underscoring): Add appropriate stuff
+	for the -f(no-)underscoring options.
+
+Tue Aug 22 10:25:01 1995  Craig Burley  (burley@gnu.ai.mit.edu)
+
+	* bad.c (ffebad_finish): Call report_error_function (in toplev.c)

+	Say "(continued):" instead of "(continued:)" for consistency.
+
+	* com.c (ffecom_gen_sfuncdef_): Set and reset new
+	ffecom_nested_entry_ variable to hold ffesymbol being compiled.
+	(lang_print_error_function): New function from toplev.c.
+	Use ffecom_nested_entry_ to help determine which name
+	and kind-string to print.
+	(ffecom_expr_intrinsic_): Handle EXIT and FLUSH invocations
+	with different calling sequences than library functions.
+	Have SIGNAL and SYSTEM push and pop calltemps, and convert
+	their return values to the destination type (just in case).
+	(FFECOM_rttypeINT_): New return type for `int', in case
+	gcc/f/runtime/libF77/system_.c(system_) is really supposed
+	to return `int' instead of `ftnint'.
+
+	* com.h (report_error_function): Declare this.
+
+	* equiv.c (ffeequiv_layout_local_): Don't forget to consider
+	root variable itself as possible "first rooted variable",
+	else might never set symbol and then crash later.
+
+	* intrin.c (ffeintrin_check_exit_): Change to allow no args
+	and rename to ffeintrin_check_int_1_o_ for `optional'.
+	#define ffeintrin_check_exit_ and _flush_ to this new
+	function, so intrin.def can refer to the appropriate names.
+
+	* intrin.def (FFEINTRIN_impFLUSH): Validate using
+	ffeintrin_check_flush_ so passing an INTEGER arg is allowed.
+
+	* lex.c (ffelex_file_push_, ffelex_file_pop_): New functions
+	to manage input_file_stack in gbe.
+	(ffelex_hash_): Call new functions (instead of doing code).
+	(ffelex_include_): Call new functions to update stack for
+	INCLUDE (_hash_ handles cpp output of #include).
+
+Mon Aug 21 08:09:04 1995  Craig Burley  (burley@gnu.ai.mit.edu)
+
+	* Makefile.in: Put `-W' in front of every `-Wall', since
+	2.7.0 requires that to engage `-Wunused' for parameters.
+
+	* com.c: Mark all parameters as artificial, so
+	`-W -Wunused' doesn't complain about unused ones (since
+	there's no way right not to individually specify attributes
+	like `unused').
+
+	* proj.h: Don't #define UNUSED if already defined, regardless
+	of host compiler.
+
+Sun Aug 20 16:03:56 1995  Craig Burley  (burley@gnu.ai.mit.edu)
+
+	* gbe/2.7.0.diff: Regenerate.
+
+	* lang-options.h, lang-specs.h: If not __STDC__ (ANSI C),
+	avoid doing anything, especially the stringizing in -specs.h.
+
+Thu Aug 17 03:36:12 1995  Craig Burley  (burley@gnu.ai.mit.edu)
+
+	* lang-specs.h: Remove useless optional settings of -traditional,
+	since -traditional is always set anyway.
+
+Wed Aug 16 16:56:46 1995  Craig Burley  (burley@gnu.ai.mit.edu)
+
+	* Make-lang.in (F2C_INSTALL_FLAG, F2CLIBOK): More
+	control over whether to install f2c-related stuff.
+	(install-f2c-*): New targets to install f2c-related
+	stuff in system, not just gcc, directories.
+
+	* com.c: Change calls to ffecom_get_invented_identifier
+	to use generally more predictable names.
+	Change calls to build_range_type to ensure consistency
+	of types of operands.
+	(ffecom_get_external_identifier_): Change to accept
+	symbol info, not just text, so it can use f2c flag for
+	symbol to decide whether to append underscore(s).
+	(ffecom_get_identifier_): Don't change names if f2c flag
+	off for compilation.
+	(ffecom_type_permanent_copy_): Use same type for new max as
+	used for min.
+	(ffecom_notify_init_storage): Offline fixups for stand-alone.
+
+	* data.c (ffedata_gather): Explicitly test for common block,
+	since it's no longer always the case that a local EQUIVALENCE
+	group has no symbol ptr (it now can, if a user-predictable
+	"rooted" symbol has been identified).
+
+	* equiv.c: Add some debugging stuff.
+	(ffeequiv_layout_local_): Set symbol ptr with user-predictable
+	"rooted" symbol, for giving the invented aggregate a
+	predictable name.
+
+	* g77.c (append_arg): Allow for 20 extra args instead of 10.
+	(main): For version-only case, add `-fnull-version' and, unless
+	explicitly omitted, `-lf2c -lm'.
+
+	* lang-options.h: New "-fnull-version" option.
+
+	* lang-specs.h: Support ".fpp" suffix for preprocessed source
+	(useful for OS/2, MS-DOS, other case-insensitive systems).
+
+	* stc.c (ffestc_R544_equiv_): Swap way lists are merged so this
+	is consistent with the order in which lists are built, making
+	user predictability of invented aggregate name much higher.
+
+	* storag.c, storag.h (FFESTORAG_typeDUMMY): Delete this enum.
+
+	* top.c: Accept, but otherwise ignore, `-fnull-version'.
+
+Tue Aug 15 07:01:07 1995  Craig Burley  (burley@gnu.ai.mit.edu)
+
+	* DOC, INSTALL, PROJECTS: Extensive improvements to documentation.
+
+Sun Aug 13 01:55:18 1995  Craig Burley  (burley@gnu.ai.mit.edu)
+
+	* INSTALL (f77-install-ok): Document the use of this file.
+
+	* Make-lang.in (F77_INSTALL_FLAG): New flag to control
+	whether to install an `f77' command (based on whether
+	a file named `f77-install-ok' exists in the source or
+	build directory) to replace the broken attempt to use
+	comment lines to avoid installing `f77' (broken in the
+	sense that it prevented installation of `g77').
+
+Mon Aug  7 06:14:26 1995  Craig Burley  (burley@gnu.ai.mit.edu)
+
+	* DOC: Add new sections for g77 & gcc compiler options,
+	source code form, and types, sizes and precisions.

+	summarize it.
+
+	* INSTALL: Add info here that used to be in DOC.
+	Other changes.
+
+	* g77.c (lookup_option, main): Check for --print-* options,

+
+	* bad.c (ffebad_here): Okay to use unknown line/col.
+
+	* compilers.h (@f77-cpp-input): Remove -P option now that
+	# directives are handled by f771.  Update other options
+	to be more consistent with @c in gcc/gcc.c.  Don't run f771
+	if -E specified, etc., a la @c.
+	(@f77): Don't run f771 if -E specified, etc., a la @c.
+
+	* config-lang.in: Avoid use of word "guaranteed".

+	following successful INCLUDE.
+	(ffelex_next_line_): New function that does chunk of code
+	seen in several places elsewhere in the lexers.
+	(ffelex_file_fixed): Delay finishing statement until source
+	line is registered with ffewhere, so INCLUDE processing
+	picks up the info correctly.
+	Okay to kill or use unknown line/col objects now.
+	Handle HASH (#) lines.
+	Reorder tests for insubstantial lines to put most frequent
+	occurrences at top, for possible minor speedup.
+	Some general consolidation of code.

+	* options-lang.h (-fident, -fno-ident): New options.
+
+	* stw.c (ffestw_update): Okay to kill unknown line/col objects
+	now.
+
+	* target.h (FFETARGET_okREALQUAD, FFETARGET_okCOMPLEXDOUBLE,
+	FFETARGET_okCOMPLEXQUAD): #define these appropriately.
+
+	* top.c: Include flag.j wrapper, not flags.h directly.
+	(ffe_is_ident_): New flag.

+
+Mon Jul 17 03:04:09 1995  Craig Burley  (burley@gnu.ai.mit.edu)
+
+	* com.c (ffecom_sym_transform_): Set DECL_IN_SYSTEM_HEADER
+	flag for any local vars used as stmtfunc dummies or DATA
+	implied-DO iter vars, so no -Wunused warnings are produced
+	for them (a la f2c).
+	(ffecom_init_0): Do "extern int xargc;" for IARGC() intrinsic.
+	Warn if target machine not 32 bits, since g77 isn't yet
+	working on them at all well.
+
+	* expr.c (ffeexpr_sym_lhs_call_, ffeexpr_sym_lhs_data_,
+	ffeexpr_sym_lhs_extfunc_, ffeexpr_sym_rhs_actualarg_,
+	ffeexpr_sym_rhs_let_, ffeexpr_paren_rhs_let_): Don't
+	gratuitously set attr bits that don't apply just
+	to avoid null set meaning error; instead, use explicit
+	error flag, and allow null attr set, to
+	fix certain bugs discovered by looking at this code.
+
+	* g77.c: Major changes to improve support for gcc long options,
+	to make `g77 -v' report more useful info, and so on.
+
+Mon Jul  3 14:49:16 1995  Craig Burley  (burley@gnu.ai.mit.edu)
+
+	* DOC, com.c, intrin.h, intrin.c, intrin.def, target.h, top.c,

+
+Tue Jun 27 23:01:05 1995  Craig Burley  (burley@gnu.ai.mit.edu)
+
+	* bld.c, bld.h (ffebld_constant_pool,
+	ffebld_constant_character_pool): Use a single macro (the
+	former) to access the pool for allocating constants, instead
+	of latter in public and FFEBLD_CONSTANT_POOL_ internally
+	in bld.c (which was the only one that was correct before
+	these changes).  Add verification of integrity of certain
+	heap-allocated areas.
+
+	* com.c (ffecom_overlap_, ffecom_args_overlap_,
+	ffecom_tree_canonize_ptr_, ffecom_tree_canonize_ref_): New
+	functions to optimize calling COMPLEX and, someday, CHARACTER
+	functions requiring additional argument to be passed.
+	(ffecom_call_, ffecom_call_binop_, ffecom_expr_,
+	ffecom_expr_intrinsic_): Change calling
+	sequences to include more info on possible destination.
+	(ffecom_expr_intrinsic_): Add ERF(), ERFC(), and EXIT()
+	intrinsic code.
+	(ffecom_sym_transform_): For assumed-size arrays, set high
+	bound to highest possible value instead of low bound, to
+	improve validity of overlap checking.
+	(duplicate_decls): If olddecl and newdecl are the same,
+	don't do any munging, just return affirmative.
+
+	* expr.c: Change ffecom_constant_character_pool() to
+	ffecom_constant_pool().
+
+	* info.c (ffeinfo_new): Compile this version if not being
+	compiled by GNU C.
+
+	* info.h (ffeinfo_new): Don't define macro if not being
+	compiled by GNU C.
+
+	* intrin.c, intrin.def: Add ERF(), ERFC(), and EXIT() intrinsics.
+	(ffeintrin_check_exit_): New for EXIT() subroutine intrinsic.
+
+	* malloc.c, malloc.h (malloc_verify_*): New functions to verify
+	integrity of heap-storage areas.
+
+	* stc.c (ffestc_R834, ffestc_R835): Handle possibility that
+	an enclosing DO won't have a construct name even when the
+	CYCLE/EXIT does (i.e. without dereferencing NULL).
+
+	* target.c, target.h (ffetarget_verify_character1): New function
+	to verify integrity of heap storage used to hold character constant.
+
+Thu Jun 22 15:36:39 1995  Howard Gordon  (flash@super.org)
+
+	* stp.h (ffestpVxtcodeIx): Fix typo in typedef for this.
+
+Mon May 29 15:22:31 1995  Craig Burley  (burley@gnu.ai.mit.edu)
+
+	* *: Make all sorts of changes to accommodate upcoming gcc-2.7.0.
+	I didn't keep track of them, nor just when I made them, nor
+	when I (much later, probably in early August 1995) modified
+	them so they could properly handle both 2.7.0 and 2.6.x.
+
+	* com.c (ffecom_expr_power_integer_): Don't expand_start_stmt_expr
+	if transforming dummy args, because the back end cannot handle
+	that (it's rejected by the gcc front end), just generate
+	call to run-time library.
+	Back out changes in 0.5.15 because more temporaries might be
+	needed anyway (for COMPLEX**INTEGER).
+	(ffecom_push_tempvar): Remove inhibitor.
+	Around start_decl and finish_decl (in particular, arround
+	expand_decl, which is called by them), push NULL_TREE into
+	sequence_rtl_expr, an external published by gcc/function.c.
+	This makes sure the temporary is truly in the function's
+	context, not the inner context of a statement-valued expression.
+	(I think the back end is inconsistent here, but am not
+	interested in convincing the gbe maintainers about this now.)
+	(pushdecl): Make sure that when pushing PARM_DECLs, nothing
+	other than them are pushed, as happened for 0.5.15 and which,
+	if done for other reasons not fixed here, might well indicate
+	some other problem -- so crash if it happens.
+
+	* equiv.c (ffeequiv_layout_local_): If the local equiv group
+	has a non-nil COMMON field, it should mean that an error has
+	occurred and been reported, so just trash the local equiv
+	group and do nothing.
+
+	* stc.c (ffestc_promote_sfdummy_): Set sfdummy arg state to
+	UNDERSTOOD so above checking for duplicate args actually
+	works, and so we don't crash later in pushdecl.
+
+	* ste.c (ffeste_R1001): Set initial value only for VAR_DECLs,
+	not for, e.g., LABEL_DECLs, which the FORMAT label can be
+	if it was previously treated as an executable label.
+
+Sat May 20 01:53:53 1995  Craig Burley  (burley@gnu.ai.mit.edu)
+
+	* com.c (ffecom_sym_transform_): For adjustable arrays,
+	pass high bound through variable_size in case its primaries
+	are changed (dumb0.f, and this might also improve
+	performance so it approaches f2c|gcc).
+
+Fri May 19 11:00:36 1995  Craig Burley  (burley@gnu.ai.mit.edu)
+
+	* Version 0.5.15 released.
+
+	* com.c (ffecom_expr_power_integer_): Push temp vars
+	before expanding a statement expression, since that seems
+	to cause temp vars to be "forgotten" after the end of the
+	expansion in the back end.  Disallow more temp-var
+	pushing during such an expansion, just in case.
+	(ffecom_push_tempvar): Crash if a new variable needs to be
+	pushed but cannot be at this point (should never happen).
+
+Wed May 17 12:26:16 1995  Craig Burley  (burley@gnu.ai.mit.edu)
+
+	* expr.c (ffeexpr_collapse_convert): Add code to convert
+	LOGICAL to CHARACTER.  Reject conversion of REAL or COMPLEX
+	to CHARACTER entirely, as it cannot be supported with all
+	configurations.
+
+	* target.h, target.c (ffetarget_convert_character1_logical1):
+	New function.
+
+Sun May 14 00:00:09 1995  Craig Burley  (burley@gnu.ai.mit.edu)
+
+	* com.c (ffecom_do_entry_, ffecom_gen_sfuncdef_,
+	ffecom_start_progunit_, ffecom_sym_transform_,
+	ffecom_init_0, start_function): Changes to have REAL
+	external functions return same type as DOUBLE PRECISION
+	external functions when -ff2c is in force; while at it,
+	some code cleanups done.
+
+	* stc.c (ffestc_R547_item_object): Disallow array declarator
+	if one already exists for symbol.
+
+	* ste.c (ffeste_R1227): Convert result variable to type
+	of function result as seen by back end (e.g. for when REAL
+	external function actually returns result as double).
+
+	* target.h (FFETARGET_defaultFIXED_LINE_LENGTH): New
+	macro for default for -ffixed-line-length-N option.
+
+	* top.c (ffe_fixed_line_length_): Initialize this to new
+	target.h macro instead of constant 72.
+
+Tue May  9 01:20:03 1995  Craig Burley  (burley@gnu.ai.mit.edu)
+
+	* lex.c (ffelex_send_token_): If sending CHARACTER token with
+	null text field, put a single '\0' in it and set length/size
+	fields to 0 (to fix 950508-0.f).
+	(ffelex_image_char_): When setting ffelex_bad_line_ to TRUE,
+	always "close" card image by appending a null char and setting
+	ffelex_card_length_.  As part of this, append useful text
+	to identify the two kinds of problems that involve this.
+	(ffelex_file_fixed): Reset ffelex_bad_line_ to FALSE after
+	seeing a line with invalid first character (fixes 950508-1.f).
+	If final nontab column is zero, assume tab seen in line.
+	(ffelex_card_image_): Always make this array 8 characters
+	longer than reflected by ffelex_card_size_.
+	(ffelex_init_1): Get final nontab column info from top instead
+	of assuming 72.
+
+	* options-lang.h: Add -ffixed-line-length- prefix.
+
+	* top.h: Add ffe_fixed_line_length() and _set_ version, plus
+	corresponding extern.
+
+	* top.c: Handle -ffixed-line-length- option prefix.
+
+Fri Apr 28 05:40:25 1995  Craig Burley  (burley@gnu.ai.mit.edu)
+
+	* Version 0.5.14 released.
+
+	* Make-lang.in: Add assert.j.
+
+	* Makefile.in: Add assert.j.
+
+	* assert.j: New file.
+
+Thu Apr 27 16:24:22 1995  Craig Burley  (burley@gnu.ai.mit.edu)
+
+	* bad.h (ffebad_severity): New function.
+
+	* bad.c (ffebad_severity): New function.
+
+	* bad.def (FFEBAD_OPEN_INCLUDE): Change severity from SEVERE
+	to FATAL, since processing continues, and that seems fine.
+
+	* com.c: Add facility to handle -I.
+	(ffecom_file, ffecom_close_include, ffecom_open_include,
+	ffecom_decode_include_option): New global functions for -I.
+	(ffecom_file_, ffecom_initialize_char_syntax_,
+	ffecom_close_include_, ffecom_decode_include_option_,
+	ffecom_open_include_, append_include_chain, open_include_file,
+	print_containing_files, read_filename_string, file_name_map,
+	savestring): New internal functions for -I.
+
+	* compilers.h: Pass -I flag(s) to f771 (via "%{I*}").
+
+	* lex.c (ffelex_include_): Call ffecom_close_include
+	to close include file, for its tracking needs for -I,
+	instead of using fclose.
+
+	* options-lang.h: Add -I prefix.
+
+	* parse.c (yyparse): Call ffecom_file for main input file,
+	so -I handling works (diagnostics).
+
+	* std.c (ffestd_S3P4): Have ffecom_open_include handle
+	opening and diagnosing errors with INCLUDE files.
+
+	* ste.c (ffeste_begin_iterdo_): Use correct algorithm for
+	calculating # of iterations -- mathematically similar but
+	computationally different algorithm was not handling cases
+	like "DO I=6,5,2" correctly, because (5-6)/2+1 => 1, not 0.
+
+	* top.c (ffe_decode_option): Allow -I, restructure a bit
+	for clarity and, maybe, speed.
+
+Mon Apr 17 13:31:11 1995  Craig Burley  (burley@gnu.ai.mit.edu)
+
+	* g77.c: Remove -lc, turns out not all systems has it, but
+	leave other changes in for clarity of code.
+
+Sun Apr 16 21:50:33 1995  Craig Burley  (burley@gnu.ai.mit.edu)
+
+	* com.c (ffecom_expr_): Implement ARRAY_EXPR as INDIRECT_REF
+	of appropriate PLUS_EXPRs of ptr_to_expr of array, to see
+	if this generates better code.  (Conditional on
+	FFECOM_FASTER_ARRAY_REFS.)
+
+Sun Apr 16 00:22:48 1995  Craig Burley  (burley@gnu.ai.mit.edu)
+
+	* Make-lang.in (F77_SRCS): Remove g77.c, since it doesn't
+	contribute to building f771.
+
+	* Makefile.in (dircheck): Remove/replace with f/Makefile, because
+	phony targets that are referenced in other real targets get run
+	when those targets are specified, which is a waste of time (e.g.
+	when rebuilding and only g77.c has changed, f771 was being linked
+	anyway).
+
+	* g77.c: Include -lc between -lf2c and -lm throughout.
+
+	* implic.c (ffeimplic_establish_symbol): If -Wimplicit, warn if
+	implicit type given to symbol.
+
+	* lex.c (ffelex_include_): Don't gratuitously increment line
+	number here.

+	related access macros.
+	(ffe_decode_option): Handle -W options, including -Wall and
+	-Wimplicit.
+
+	* where.c (ffewhere_line_new): Don't muck with root line (was
+	crashing on null input since lexer changes over the past week
+	or so).
+
+Thu Apr 13 16:48:30 1995  Craig Burley  (burley@gnu.ai.mit.edu)
+
+	* com.c (ffecom_init_0): Register built-in functions for cos,
+	sin, and sqrt.
+	(ffecom_tree_fun_type_double): New variable.
+	(ffecom_expr_intrinsic_): Update f2c input and output files
+	to latest version of f2c (no important g77-related changes
+	noted, just bug fixes to f2c and such).
+	(builtin_function): New function from c-decl.c.
+
+	* com-rt.def: Refer to built-in functions for cos, sin, and sqrt.
+
+Thu Apr 13 10:25:09 1995  Craig Burley  (burley@gnu.ai.mit.edu)
+
+	* com.c (ffecom_expr_intrinsic_): Convert 0. to appropriate
+	type to keep DCMPLX(I) from crashing the compiler.
+	(ffecom_expr_): Don't convert result from ffecom_tree_divide_.
+	(ffecom_tree_divide_): Add tree_type argument, have all callers
+	pass one, and don't convert right-hand operand to it (this is
+	to make this new function work as much like the old in-line
+	code used in ffecom_expr_ as possible).
+
+	* lex.c: Maintain lineno and input_filename the way the gcc
+	lexer does.
+
+	* std.c (ffestd_exec_end): Save and restore lineno and
+	input_filename around the second pass, which sets them
+	appropriately for each saved statement.
+
+Wed Apr 12 09:44:45 1995  Craig Burley  (burley@gnu.ai.mit.edu)
+
+	* com.c (ffecom_expr_power_integer_): New function.
+	(ffecom_expr_): Call new function for power op with integer second
+	argument, for generating better code.  Also replace divide
+	code with call to new ffecom_tree_divide_ function.
+	Canonicalize calls to ffecom_truth_value(_invert).
+	(ffecom_tree_divide_): New function.
+
+Wed Apr  5 14:15:44 1995  Craig Burley  (burley@gnu.ai.mit.edu)
+
+	* lex.c: Change to allocate text for tokens only when actually
+	needed, which should speed compilation up somewhat.
+	Change to allow INCLUDE at any point where a statement
+	can end, i.e. in ffelex_finish_statement_ or when a SEMICOLON
+	token is sent.
+	Remove some old, obsolete code.
+	Clean up layout of entire file to improve formatting,
+	readability, etc.
+	(ffelex_set_expecting_hollerith): Remove include argument.
+
+Fri Mar 31 23:19:08 1995  Craig Burley  (burley@gnu.ai.mit.edu)

+	backslash processing.
+
+	* std.c (ffestd_R1001dump_): Don't assume CHARACTER and
+	HOLLERITH tokens stop at '\0' characters, now that backslash
+	processing is supported -- use their advertised lengths instead,
+	and double up the '\002' character for libf2c.
+
+Mon Mar 27 17:10:33 1995  Craig Burley  (burley@gnu.ai.mit.edu)
+
+	* com.c (ffecom_init_local_zero_): Implement -finit-local-zero.

+	(ffecom_transform_equiv_): Same.
+
+	* options-lang.h: Add -f(no-)(init-local-zero,backslash,ugly-init).
+
+	* stb.c (ffestb_V020): Reject "TYPEblah(...", which might be
+	an array assignment.
+
+	* target.h, top.h, top.c: Implement -finit-local-zero.
+
+Fri Mar 24 19:56:22 1995  Craig Burley  (burley@gnu.ai.mit.edu)
+
+	* Make-lang.in, Makefile.in: Remove conf-proj(.in) and
+	proj.h(.in) rules, plus related config.log, config.cache,
+	and config.status stuff.
+
+	* com.c (ffecom_init_0): Change messages when atof(), bsearch(),
+	or strtoul() do not work as expected in the start-up test.
+
+	* conf-proj, conf-proj.in: Delete.
+
+	* lex.c (ffelex_file_fixed): Allow f2c's '&' in column 1

+
+Mon Mar 13 10:46:13 1995  Craig Burley  (burley@gnu.ai.mit.edu)
+
+	* BUGS: Add item about g77 requiring gcc to compile it.
+
+	* NEWS: New file listing user-visible changes in the release.
+
+	* PROJECTS: Update to include a new item or two, and modify
+	or delete items that are addressed in this or previous releases.
+
+	* bad.c (ffebad_finish): Don't crash if missing string &c,
+	just substitute obviously distressed string "[REPORT BUG!!]"
+	for cases where the message/caller are fudgy.
+
+	* bad.def: Clean up error messages in a major way, add new ones
+	for use by changes in target.c.
+
+	* com.c (ffecom_expr_): Handle opANY in opCONVERT.

+	(ffecom_1, ffecom_1_fn, ffecom_2, ffecom_2s, ffecom_3,
+	ffecom_3s, &c): Check all inputs for error_mark_node.
+	(ffecom_start_progunit_): Don't transform all symbols
+	in BLOCK DATA, since it never executes, and it is silly
+	to, e.g., generate all the structures for NAMELIST.
+	(ffecom_char_length_expr_): Rename to ffecom_intrinsic_len_.
+	(ffecom_intrinsic_ichar_): New function to handle ICHAR of
+	arbitrary expression with possible 0-length operands.
+	(ffecom_expr_intrinsic_): Use ffecom_intrinsic_char_.
+	For MVBITS, set tree_type to void_type_node.
+	(ffecom_start_progunit_): Name master function for entry points
+	after primary entry point so users can easily guess it while
+	debugging.
+	(ffecom_arg_ptr_to_expr): Change treatment of Hollerith,
+	Typeless, and %DESCR.
+	(ffecom_expr_): Change treatment of Hollerith.
+
+	* data.c (ffedata_gather_): Handle opANY in opCONVERT.
+
+	* expr.c (ffeexpr_token_apostrophe_): Issue FFEBAD_NULL_CHAR_CONST
+	warning as necessary.
+	(ffeexpr_token_name_rhs_): Set context for args to intrinsic
+	so that assignment-like concatenation is allowed for ICHAR(),
+	IACHAR(), and LEN() intrinsics.
+	(ffeexpr_reduced_*_): Say "an array" instead of "an entity" in
+	diagnostics, since it's more informative.
+	(ffeexpr_finished_): For many contexts, check for null expression
+	and array before trying to do a conversion, to avoid redundant

+	blank common.
+	(ffeglobal_pad_common): Enable code to warn if initial

+	to global (largest-known) size, even though size of init might
+	be smaller.
+
+	* equiv.c (ffeequiv_offset_): Check symbol info for ANY.
+
+	* expr.c (ffeexpr_find_close_paren_, ffeexpr_nil_*): New functions
+	to handle following the contour of a rejected expression, so
+	statements like "PRINT(I,I,I)=0" don't cause the PRINT statement
+	code to get the second passed back to it as if there was a
+	missing close-paren before it, the comma causing the PRINT code
+	to confirm the statement, resulting in an ambiguity vis-a-vis
+	the let statement code.
+	Use the new ffecom_find_close_paren_ handler when an expected
+	close-paren is missing.
+	(ffeexpr_isdigits_): New function, use in all places that
+	currently use isdigit in repetitive code.
+	(ffeexpr_collapse_symter): Collapse to ANY if init-expr is ANY,

+	anytime calculation of number of iterations ends up with type
+	other than INTEGER (e.g. DOUBLE PRECISION, REAL).

+	(non-statement-function) f2c functions.
+	(ffecom_init_0): ffecom_tree_fun_type[][] and _ptr_to_*_* are

+
+	* Make-lang.in (f77.install-common): Expurgate the test for and

+
+	* com.c (ffecom_start_progunit_): If non-multi alt-entry

+
+	* com.h (ffecom_expr_assign, ffecom_expr_assign_rw): New decls.
+	(error): Add this prototype for back-end function.
+
+	* fini.c (main): Grab input, output, and include names
+	directly off the command line instead of making the latter
+	two out of the first.
+
+	* lex.c: Improve tab handling for both fixed and free source
+	forms, and ignore carriage-returns on input, while generally
+	improving the code.  ffelex_handle_tab_ has been renamed and
+	reinvented as ffelex_image_char_, among other things.
+
+	* malloc.c, malloc.h: Switch to valid ANSI C replacement for

+
+	* INSTALL: In quick-build case, list g77 target first so g77
+	gets installed.  Also, explain that gcc gets built and installed
+	as well, even though this isn't really what we want (and maybe
+	we'll find a way around this someday).
+
+Fri Feb 17 02:35:41 1995  Craig Burley  (burley@gnu.ai.mit.edu)
+
+	* Version 0.5.7 released.

+
+	* README.NEXTSTEP: Credit Toon, and per his request, add his

+	* config.j, convert.j, flags.j, hconfig.j, rtl.j, tconfig.j,

+
+	* convert.j: #include "tree.j" first, as convert.h clearly depends
+	on trees being defined.
+
+	* rtl.j: #include "config.j" first, since there's some stuff
+	in rtl.h that assumes it has been #included.
+
+	* tree.j: #include "config.j" first, or real.h makes inconsistent
+	decision about return type of ereal_atof, leading to bugs, and
+	because tree.h/real.h assume config.h already included.
+
+Wed Feb 15 14:40:20 1995  Craig Burley  (burley@gnu.ai.mit.edu)

+	Accommodate changes in output of gcc -MM.
+

+
+	* com.c (ffecom_init_0): Use FLOAT_TYPE_SIZE for f2c's
+	TYLONG/TYLOGICAL type codes, to get g77 working on Alpha.

+
+	* config.h, convert.h, flags.h, glimits.h, hconfig.h, rtl.h,
+	tconfig.h, tm.h, tree.h: Deleted so new .j files
+	can #include the gbe files directly, instead of using "../",
+	and thus do better with various kinds of builds.
+
+	* proj.h: Delete unused NO_STDDEF and related stuff.

+
+Sat Feb 11 20:56:02 1995  Craig Burley  (burley@gnu.ai.mit.edu)

+
+Sat Feb 11 09:51:57 1995  Craig Burley  (burley@gnu.ai.mit.edu)
+
+	* ste.c: In I/O code tests for item arrayness, sort of revert
+	to much earlier code that tests original exp, but also check
+	in newer way just in case.  Newer way alone treated FOO(1:40)
+	as an array, not sure why older way alone didn't work, but I
+	think maybe it was when diagnosed code was involved, and
+	since there are now checks for error_mark_node, maybe the old
+	way alone would work.  But better to be safe; both original
+	ffebld exp _and_ the transformed tree must indicate an array
+	for the size-determination code to be used, else just 1/2 elements
+	assumed.  And this text is for EMACS: (foo at bar).
+
+Fri Feb 10 11:05:50 1995  Craig Burley  (burley@gnu.ai.mit.edu)
+
+	* ste.c: In many cases, surround statement-expansion code
+	with ffecom_push_calltemps () and ffecom_pop_calltemps ()
+	so COMPLEX-returning functions can have temporaries pushed
+	in "auto-pop" mode and have them auto-popped at the end of
+	the statement.

+	check for LAME_STDIO (cosmetic only with ANSI C).
+
+	* com.h: Extra ...SIZE stuff taken from com.c.
+
+	* com.c (FFECOM_DETERMINE_TYPES): Define before including com.h.
+	(BITS_PER_WORD etc.) Remove and use conditional definitions to com.h.
+
+	* runtime/configure.in: #define FFECOM_DETERMINE_TYPES for com.h in
+	f2c type determination.

+	Rewrite arglist mechanism for ease of maintenance.
+	Make sure every -lf2c is followed by -lm and vice versa.
+
+	* Make-lang.in: Put complete list of sources in F77_SRCS def

+
+	* g77.c: Avoid putting out useless "-xnone -xf77" pairs so
+	larger command lines can be accommodated.
+	Recognize both `-xlang' and `-x lang'.
+	Recognize `-xnone' and `-x none' to mean what it does, instead
+	of treating "none" as any other language.
+	Some minor, slight improvements in the way args are handled
+	(hopefully for clearer, more maintainable code), including
+	consistency checks on arg count just in case.
+
+Wed Jan 18 16:41:57 1995  Craig Burley  (burley@gnu.ai.mit.edu)
+
+	* DOC: Explain -fautomatic better.
+
+	* INSTALL: Describe libf2c.a better.
+

+	Add new source file type.c.
+
+	* Makefile.in: For nextstep3, link f771 with -segaddr __DATA
+	6000000.  Fix typo.  Change deps-kinda target to handle building
+	from gcc/.  Update dependencies.

+	* bld-op.def, bld.h, bld.c: Remove opBACKEND and all related
+	stuff.
+	Remove consistency tests that cause compiler warnings.
+
+	* cktyps.c: Remove all typing checking.
+
+	* com-rt.def: Change all rttypeFLOAT_ intrinsics to rttypeDOUBLE_,
+	to precisely match how they're declared in libf2c.
+
+	* com.h, com.c: Revise to more elegantly track related stuff
+	in the version of f2c.h used to build libf2c.
+
+	* com.c: Increase FFECOM_sizeMAXSTACKITEM, and if 0 or undefined
+	when checked to determine where to put entity, treat as infinite.
+	Rewrite temporary mechanism to be based on trees instead of
+	ffeinfo stuff, and make it much simpler.  Change interface
+	accordingly.
+	Fixes to better track types of things, make appropriate
+	conversions, etc.  E.g. when making an arg for a libf2c
+	function, make sure it's of the right type (such as ftnlen).
+	Delete opBACKEND transformation code.
+	(ffecom_init_0): Smoother initialization of types, especially
+	paying attention to using consistent rules for making INTEGER,
+	REAL, DOUBLE PRECISION, etc., and for deciding their "*N"
+	and kind values that will work across all g77 platforms.
+	No longer require per-target configuration info in target.h
+	or config/*/*; use new type module to store size, alignment.
+	(ffecom_member_phase2): Declare COMMON/EQUIVALENCE group members
+	so debugger sees them.
+	(ffecom_finish_progunit): Transform all symbols in program unit,
+	so -g will show they all exist.
+
+	* expr.c (ffeexpr_collapse_substr): Handle strange substring
+	range values.
+
+	* info.h, info.c: Provide connection to new type module.
+	Remove tests that yield compiler warnings.

+
+	* stc.c (ffestc_kindtype_kind_, ffestc_kindtype_star_): Replace
+	boring switch stmt with simple call to new type module.  This
+	sort of thing is a reason to get up in the morning.
+
+	* ste.c: Update to handle new interface for
+	ffecom_push/pop_tempvar.
+	Fixes to better track types of things.
+	Fixes to not crash for certain diagnosed constructs.
+	(ffeste_begin_iterdo_): Check only constants for overflow to avoid
+	spurious diagnostics.
+	Don't convert larger integer (say, INTEGER*8) to canonical integer
+	for iteration count.
+
+	* stw.h: Track DO iteration count temporary variable.
+
+	* symbol.c: Remove consistency tests that cause compiler warnings.
+
+	* target.c (ffetarget_aggregate_info): Replace big switch with
+	little call to new type module.

+	compiler warnings.
+	(ffetarget_convert_character1_typeless): Pick up length of
+	typeless type from new type module.
+
+	* target.h: Crash build if target float bit pattern cannot be
+	precisely determined.
+	Remove all the type cruft now determined by ffecom_init_0
+	at invocation time and maintained in new type module.
+	Put casts on second arg of all REAL_VALUE_TO_TARGET_DOUBLE
+	uses so compiler warnings avoided (requires target float bit
+	pattern to be precisely determined, hence code to crash build).
+
+	* top.c: Add inits/terminates for new type module.
+
+	* type.h, type.c: New module.
+
+	* gbe/2.6.2.diff: Remove all patches to files in gcc/config/
+	directory and its subdirectories.

+# but widely known format for documentation -- basically anyone who knows
+# how to write texinfo source and enclose it in C constants can handle
+# it, and f/ansify allows them to not even end lines with "\n\".  So,
+# essentially, the C preprocessor and compiler are used to enter the
+# document snippets into a data base via name lookup, rather than duplicating
+# that kind of code here.  And we use f/intdoc.c instead of straight
+# texinfo in the first place so that as much information as possible
+# contained in f/intrin.def can be inserted directly and reliably into
+# the documentation.  That's better than replicating it, because it
+# reduces the likelihood of discrepancies between the docs and the compiler
+# itself, which uses f/intrin.def; in fact, many bugs in f/intrin.def have

+
+News About GNU Fortran
+**********************
+
+   Changes made to recent versions of GNU Fortran are listed below,
+with the most recent version first.
+
+   The changes are generally listed in order:
+
+  1. Code-generation and run-time-library bug-fixes
+
+  2. Compiler and run-time-library crashes involving valid code that
+     have been fixed
+
+  3. New features
+
+  4. Fixes and enhancements to existing features
+
+  5. New diagnostics
+
+  6. Internal improvements
+
+  7. Miscellany
+
+   This order is not strict--for example, some items involve a
+combination of these elements.
+
+   Note that two variants of `g77' are tracked below.  The `egcs'
+variant is described vis-a-vis previous versions of `egcs' and/or an
+official FSF version, as appropriate.
+
+   Therefore, `egcs' versions sometimes have multiple listings to help
+clarify how they differ from other versions, though this can make
+getting a complete picture of what a particular `egcs' version contains
+somewhat more difficult.
+
+   An online, "live" version of this document (derived directly from
+the up-to-date mainline version of `g77' within `egcs') is available at

+
+In 0.5.24 and `egcs' 1.1.2 (versus 0.5.23 and 1.1.1):
+=====================================================
+
+   * Fix the `IDate' Intrinsic (VXT) so the returned year is in the
+     documented, non-Y2K-compliant range of 0-99, instead of being
+     returned as 100 in the year 2000.
+
+   * Fix the `Date_and_Time' intrinsic (in `libg2c') to return the
+     milliseconds value properly in VALUES(8).
+
+   * Fix the `LStat' intrinsic (in `libg2c') to return device-ID
+     information properly in SARRAY(7).
+
+   * Improve documentation.
+
+In 0.5.24 and `egcs' 1.1.1 (versus 0.5.23 and 1.1):
+===================================================
+
+   * Fix `libg2c' so it performs an implicit `ENDFILE' operation (as
+     appropriate) whenever a `REWIND' is done.
+
+     (This bug was introduced in 0.5.23 and `egcs' 1.1 in `g77''s
+     version of `libf2c'.)
+
+   * Fix `libg2c' so it no longer crashes with a spurious diagnostic
+     upon doing any I/O following a direct formatted write.
+
+     (This bug was introduced in 0.5.23 and `egcs' 1.1 in `g77''s
+     version of `libf2c'.)
+
+   * Fix `g77' so it no longer crashes compiling references to the
+     `Rand' intrinsic on some systems.
+
+   * Fix `g77' portion of installation process so it works better on
+     some systems (those with shells requiring `else true' clauses on
+     `if' constructs for the completion code to be set properly).
+
+In `egcs' 1.1 (versus 0.5.24):
+==============================
+
+   * Fix `g77' crash compiling code containing the construct
+     `CMPLX(0.)' or similar.
+
+   * Fix `g77' crash (or apparently infinite run-time) when compiling
+     certain complicated expressions involving `COMPLEX' arithmetic
+     (especially multiplication).
+
+   * Fix a code-generation bug that afflicted Intel x86 targets when
+     `-O2' was specified compiling, for example, an old version of the
+     `DNRM2' routine.
+
+     The x87 coprocessor stack was being mismanaged in cases involving
+     assigned `GOTO' and `ASSIGN'.
+
+   * Align static double-precision variables and arrays on Intel x86
+     targets regardless of whether `-malign-double' is specified.
+
+     Generally, this affects only local variables and arrays having the
+     `SAVE' attribute or given initial values via `DATA'.
+
+In `egcs' 1.1 (versus `egcs' 1.0.3):
+====================================
+
+   * Fix bugs in the `libU77' intrinsic `HostNm' that wrote one byte
+     beyond the end of its `CHARACTER' argument, and in the `libU77'
+     intrinsics `GMTime' and `LTime' that overwrote their arguments.
+
+   * Assumed arrays with negative bounds (such as `REAL A(-1:*)') no
+     longer elicit spurious diagnostics from `g77', even on systems
+     with pointers having different sizes than integers.
+
+     This bug is not known to have existed in any recent version of
+     `gcc'.  It was introduced in an early release of `egcs'.
+
+   * Valid combinations of `EXTERNAL', passing that external as a dummy
+     argument without explicitly giving it a type, and, in a subsequent
+     program unit, referencing that external as an external function
+     with a different type no longer crash `g77'.
+
+   * `CASE DEFAULT' no longer crashes `g77'.
+
+   * The `-Wunused' option no longer issues a spurious warning about
+     the "master" procedure generated by `g77' for procedures
+     containing `ENTRY' statements.
+
+   * Support `FORMAT(I<EXPR>)' when EXPR is a compile-time constant
+     `INTEGER' expression.
+
+   * Fix `g77' `-g' option so procedures that use `ENTRY' can be
+     stepped through, line by line, in `gdb'.
+
+   * Allow any `REAL' argument to intrinsics `Second' and `CPU_Time'.
+
+   * Use `tempnam', if available, to open scratch files (as in
+     `OPEN(STATUS='SCRATCH')') so that the `TMPDIR' environment
+     variable, if present, is used.
+
+   * `g77''s version of `libf2c' separates out the setting of global
+     state (such as command-line arguments and signal handling) from
+     `main.o' into distinct, new library archive members.
+
+     This should make it easier to write portable applications that
+     have their own (non-Fortran) `main()' routine properly set up the
+     `libf2c' environment, even when `libf2c' (now `libg2c') is a
+     shared library.
+
+   * `g77' no longer installs the `f77' command and `f77.1' man page in
+     the `/usr' or `/usr/local' heirarchy, even if the `f77-install-ok'
+     file exists in the source or build directory.  See the
+     installation documentation for more information.
+
+   * `g77' no longer installs the `libf2c.a' library and `f2c.h'
+     include file in the `/usr' or `/usr/local' heirarchy, even if the
+     `f2c-install-ok' or `f2c-exists-ok' files exist in the source or
+     build directory.  See the installation documentation for more
+     information.
+
+   * The `libf2c.a' library produced by `g77' has been renamed to
+     `libg2c.a'.  It is installed only in the `gcc' "private" directory
+     heirarchy, `gcc-lib'.  This allows system administrators and users
+     to choose which version of the `libf2c' library from `netlib' they
+     wish to use on a case-by-case basis.  See the installation
+     documentation for more information.
+
+   * The `f2c.h' include (header) file produced by `g77' has been
+     renamed to `g2c.h'.  It is installed only in the `gcc' "private"
+     directory heirarchy, `gcc-lib'.  This allows system administrators
+     and users to choose which version of the include file from
+     `netlib' they wish to use on a case-by-case basis.  See the
+     installation documentation for more information.
+
+   * The `g77' command now expects the run-time library to be named
+     `libg2c.a' instead of `libf2c.a', to ensure that a version other
+     than the one built and installed as part of the same `g77' version
+     is picked up.
+
+   * During the configuration and build process, `g77' creates
+     subdirectories it needs only as it needs them.  Other cleaning up
+     of the configuration and build process has been performed as well.
+
+   * `install-info' now used to update the directory of Info
+     documentation to contain an entry for `g77' (during installation).
+
+   * Some diagnostics have been changed from warnings to errors, to
+     prevent inadvertent use of the resulting, probably buggy, programs.
+     These mostly include diagnostics about use of unsupported features
+     in the `OPEN', `INQUIRE', `READ', and `WRITE' statements, and
+     about truncations of various sorts of constants.
+
+   * Improve compilation of `FORMAT' expressions so that a null byte is
+     appended to the last operand if it is a constant.  This provides a
+     cleaner run-time diagnostic as provided by `libf2c' for statements
+     like `PRINT '(I1', 42'.
+
+   * Improve documentation and indexing.
+
+   * The upgrade to `libf2c' as of 1998-06-18 should fix a variety of
+     problems, including those involving some uses of the `T' format
+     specifier, and perhaps some build (porting) problems as well.
+
+In 0.5.24 and `egcs' 1.1 (versus 0.5.23):
+=========================================
+
+   * `g77' no longer produces incorrect code and initial values for
+     `EQUIVALENCE' and `COMMON' aggregates that, due to "unnatural"
+     ordering of members vis-a-vis their types, require initial padding.
+
+   * `g77' no longer crashes when compiling code containing
+     specification statements such as `INTEGER(KIND=7) PTR'.
+
+   * `g77' no longer crashes when compiling code such as `J = SIGNAL(1,
+     2)'.
+
+   * `g77' now treats `%LOC(EXPR)' and `LOC(EXPR)' as "ordinary"
+     expressions when they are used as arguments in procedure calls.
+     This change applies only to global (filewide) analysis, making it
+     consistent with how `g77' actually generates code for these cases.
+
+     Previously, `g77' treated these expressions as denoting special
+     "pointer" arguments for the purposes of filewide analysis.
+
+   * The `g77' driver now ensures that `-lg2c' is specified in the link
+     phase prior to any occurrence of `-lm'.  This prevents
+     accidentally linking to a routine in the SunOS4 `-lm' library when
+     the generated code wants to link to the one in `libf2c' (`libg2c').
+
+   * `g77' emits more debugging information when `-g' is used.
+
+     This new information allows, for example, `which __g77_length_a'
+     to be used in `gdb' to determine the type of the phantom length
+     argument supplied with `CHARACTER' variables.
+
+     This information pertains to internally-generated type, variable,
+     and other information, not to the longstanding deficiencies
+     vis-a-vis `COMMON' and `EQUIVALENCE'.
+
+   * The F90 `Date_and_Time' intrinsic now is supported.
+
+   * The F90 `System_Clock' intrinsic allows the optional arguments
+     (except for the `Count' argument) to be omitted.
+
+   * Upgrade to `libf2c' as of 1998-06-18.
+
+   * Improve documentation and indexing.
+
+In 0.5.23 (versus 0.5.22):
+==========================
+
+   * This release contains several regressions against version 0.5.22
+     of `g77', due to using the "vanilla" `gcc' back end instead of
+     patching it to fix a few bugs and improve performance in a few
+     cases.
+
+     See `egcs/gcc/f/BUGS', for information on the known bugs in this
+     version, including the regressions.
+
+     Features that have been dropped from this version of `g77' due to
+     their being implemented via `g77'-specific patches to the `gcc'
+     back end in previous releases include:
+
+        - Support for `__restrict__' keyword, the options
+          `-fargument-alias', `-fargument-noalias', and
+          `-fargument-noalias-global', and the corresponding
+          alias-analysis code.
+
+          (`egcs' has the alias-analysis code, but not the
+          `__restrict__' keyword.  `egcs' `g77' users benefit from the
+          alias-analysis code despite the lack of the `__restrict__'
+          keyword, which is a C-language construct.)
+
+        - Support for the GNU compiler options `-fmove-all-movables',
+          `-freduce-all-givs', and `-frerun-loop-opt'.
+
+          (`egcs' supports these options.  `g77' users of `egcs'
+          benefit from them even if they are not explicitly specified,
+          because the defaults are optimized for `g77' users.)
+
+        - Support for the `-W' option warning about integer division by
+          zero.
+
+        - The Intel x86-specific option `-malign-double' applying to
+          stack-allocated data as well as statically-allocate data.
+
+     Note that the `gcc/f/gbe/' subdirectory has been removed from this
+     distribution as a result of `g77' no longer including patches for
+     the `gcc' back end.
+
+   * Fix bugs in the `libU77' intrinsic `HostNm' that wrote one byte
+     beyond the end of its `CHARACTER' argument, and in the `libU77'
+     intrinsics `GMTime' and `LTime' that overwrote their arguments.
+
+   * Support `gcc' version 2.8, and remove support for prior versions
+     of `gcc'.
+
+   * Remove support for the `--driver' option, as `g77' now does all
+     the driving, just like `gcc'.
+
+   * `CASE DEFAULT' no longer crashes `g77'.
+
+   * Valid combinations of `EXTERNAL', passing that external as a dummy
+     argument without explicitly giving it a type, and, in a subsequent
+     program unit, referencing that external as an external function
+     with a different type no longer crash `g77'.
+
+   * `g77' no longer installs the `f77' command and `f77.1' man page in
+     the `/usr' or `/usr/local' heirarchy, even if the `f77-install-ok'
+     file exists in the source or build directory.  See the
+     installation documentation for more information.
+
+   * `g77' no longer installs the `libf2c.a' library and `f2c.h'
+     include file in the `/usr' or `/usr/local' heirarchy, even if the
+     `f2c-install-ok' or `f2c-exists-ok' files exist in the source or
+     build directory.  See the installation documentation for more
+     information.
+
+   * The `libf2c.a' library produced by `g77' has been renamed to
+     `libg2c.a'.  It is installed only in the `gcc' "private" directory
+     heirarchy, `gcc-lib'.  This allows system administrators and users
+     to choose which version of the `libf2c' library from `netlib' they
+     wish to use on a case-by-case basis.  See the installation
+     documentation for more information.
+
+   * The `f2c.h' include (header) file produced by `g77' has been
+     renamed to `g2c.h'.  It is installed only in the `gcc' "private"
+     directory heirarchy, `gcc-lib'.  This allows system administrators
+     and users to choose which version of the include file from
+     `netlib' they wish to use on a case-by-case basis.  See the
+     installation documentation for more information.
+
+   * The `g77' command now expects the run-time library to be named
+     `libg2c.a' instead of `libf2c.a', to ensure that a version other
+     than the one built and installed as part of the same `g77' version
+     is picked up.
+
+   * The `-Wunused' option no longer issues a spurious warning about
+     the "master" procedure generated by `g77' for procedures
+     containing `ENTRY' statements.
+
+   * `g77''s version of `libf2c' separates out the setting of global
+     state (such as command-line arguments and signal handling) from
+     `main.o' into distinct, new library archive members.
+
+     This should make it easier to write portable applications that
+     have their own (non-Fortran) `main()' routine properly set up the
+     `libf2c' environment, even when `libf2c' (now `libg2c') is a
+     shared library.
+
+   * During the configuration and build process, `g77' creates
+     subdirectories it needs only as it needs them, thus avoiding
+     unnecessary creation of, for example, `stage1/f/runtime' when
+     doing a non-bootstrap build.  Other cleaning up of the
+     configuration and build process has been performed as well.
+
+   * `install-info' now used to update the directory of Info
+     documentation to contain an entry for `g77' (during installation).
+
+   * Some diagnostics have been changed from warnings to errors, to
+     prevent inadvertent use of the resulting, probably buggy, programs.
+     These mostly include diagnostics about use of unsupported features
+     in the `OPEN', `INQUIRE', `READ', and `WRITE' statements, and
+     about truncations of various sorts of constants.
+
+   * Improve documentation and indexing.
+
+   * Upgrade to `libf2c' as of 1998-04-20.
+
+     This should fix a variety of problems, including those involving
+     some uses of the `T' format specifier, and perhaps some build
+     (porting) problems as well.
+
+In 0.5.22 (versus 0.5.21):
+==========================
+
+   * Fix code generation for iterative `DO' loops that have one or more
+     references to the iteration variable, or to aliases of it, in
+     their control expressions.  For example, `DO 10 J=2,J' now is
+     compiled correctly.
+
+   * Fix a code-generation bug that afflicted Intel x86 targets when
+     `-O2' was specified compiling, for example, an old version of the
+     `DNRM2' routine.
+
+     The x87 coprocessor stack was being mismanaged in cases involving
+     assigned `GOTO' and `ASSIGN'.
+
+   * Fix `DTime' intrinsic so as not to truncate results to integer
+     values (on some systems).
+
+   * Fix `Signal' intrinsic so it offers portable support for 64-bit
+     systems (such as Digital Alphas running GNU/Linux).
+
+   * Fix run-time crash involving `NAMELIST' on 64-bit machines such as
+     Alphas.
+
+   * Fix `g77' version of `libf2c' so it no longer produces a spurious
+     `I/O recursion' diagnostic at run time when an I/O operation (such
+     as `READ *,I') is interrupted in a manner that causes the program
+     to be terminated via the `f_exit' routine (such as via `C-c').
+
+   * Fix `g77' crash triggered by `CASE' statement with an omitted
+     lower or upper bound.
+
+   * Fix `g77' crash compiling references to `CPU_Time' intrinsic.
+
+   * Fix `g77' crash (or apparently infinite run-time) when compiling
+     certain complicated expressions involving `COMPLEX' arithmetic
+     (especially multiplication).
+
+   * Fix `g77' crash on statements such as `PRINT *,
+     (REAL(Z(I)),I=1,2)', where `Z' is `DOUBLE COMPLEX'.
+
+   * Fix a `g++' crash.
+
+   * Support `FORMAT(I<EXPR>)' when EXPR is a compile-time constant
+     `INTEGER' expression.
+
+   * Fix `g77' `-g' option so procedures that use `ENTRY' can be
+     stepped through, line by line, in `gdb'.
+
+   * Fix a profiling-related bug in `gcc' back end for Intel x86
+     architecture.
+
+   * Allow any `REAL' argument to intrinsics `Second' and `CPU_Time'.
+
+   * Allow any numeric argument to intrinsics `Int2' and `Int8'.
+
+   * Use `tempnam', if available, to open scratch files (as in
+     `OPEN(STATUS='SCRATCH')') so that the `TMPDIR' environment
+     variable, if present, is used.
+
+   * Rename the `gcc' keyword `restrict' to `__restrict__', to avoid
+     rejecting valid, existing, C programs.  Support for `restrict' is
+     now more like support for `complex'.
+
+   * Fix `-fpedantic' to not reject procedure invocations such as
+     `I=J()' and `CALL FOO()'.
+
+   * Fix `-fugly-comma' to affect invocations of only external
+     procedures.  Restore rejection of gratuitous trailing omitted
+     arguments to intrinsics, as in `I=MAX(3,4,,)'.
+
+   * Fix compiler so it accepts `-fgnu-intrinsics-*' and
+     `-fbadu77-intrinsics-*' options.
+
+   * Improve diagnostic messages from `libf2c' so it is more likely
+     that the printing of the active format string is limited to the
+     string, with no trailing garbage being printed.
+
+     (Unlike `f2c', `g77' did not append a null byte to its compiled
+     form of every format string specified via a `FORMAT' statement.
+     However, `f2c' would exhibit the problem anyway for a statement
+     like `PRINT '(I)garbage', 1' by printing `(I)garbage' as the
+     format string.)
+
+   * Improve compilation of `FORMAT' expressions so that a null byte is
+     appended to the last operand if it is a constant.  This provides a
+     cleaner run-time diagnostic as provided by `libf2c' for statements
+     like `PRINT '(I1', 42'.
+
+   * Fix various crashes involving code with diagnosed errors.
+
+   * Fix cross-compilation bug when configuring `libf2c'.
+
+   * Improve diagnostics.
+
+   * Improve documentation and indexing.
+
+   * Upgrade to `libf2c' as of 1997-09-23.  This fixes a formatted-I/O
+     bug that afflicted 64-bit systems with 32-bit integers (such as
+     Digital Alpha running GNU/Linux).
+
+In `egcs' 1.0.2 (versus `egcs' 1.0.1):
+======================================
+
+   * Fix `g77' crash triggered by `CASE' statement with an omitted
+     lower or upper bound.
+
+   * Fix `g77' crash on statements such as `PRINT *,
+     (REAL(Z(I)),I=1,2)', where `Z' is `DOUBLE COMPLEX'.
+
+   * Fix `-fPIC' (such as compiling for ELF targets) on the Intel x86
+     architecture target so invalid assembler code is no longer
+     produced.
+
+   * Fix `-fpedantic' to not reject procedure invocations such as
+     `I=J()' and `CALL FOO()'.
+
+   * Fix `-fugly-comma' to affect invocations of only external
+     procedures.  Restore rejection of gratuitous trailing omitted
+     arguments to intrinsics, as in `I=MAX(3,4,,)'.
+
+   * Fix compiler so it accepts `-fgnu-intrinsics-*' and
+     `-fbadu77-intrinsics-*' options.
+
+In `egcs' 1.0.1 (versus `egcs' 1.0):
+====================================
+
+   * Fix run-time crash involving `NAMELIST' on 64-bit machines such as
+     Alphas.
+
+In `egcs' 1.0 (versus 0.5.21):
+==============================
+
+   * Version 1.0 of `egcs' contains several regressions against version
+     0.5.21 of `g77', due to using the "vanilla" `gcc' back end instead
+     of patching it to fix a few bugs and improve performance in a few
+     cases.
+
+     See `egcs/gcc/f/BUGS', for information on the known bugs in this
+     version, including the regressions.

+
+        - The Intel x86-specific option `-malign-double' applying to
+          stack-allocated data as well as statically-allocate data.
+
+     Note that the `gcc/f/gbe/' subdirectory has been removed from this
+     distribution as a result of `g77' being fully integrated with the
+     `egcs' variant of the `gcc' back end.
+
+   * Fix code generation for iterative `DO' loops that have one or more
+     references to the iteration variable, or to aliases of it, in
+     their control expressions.  For example, `DO 10 J=2,J' now is
+     compiled correctly.
+
+   * Fix `DTime' intrinsic so as not to truncate results to integer
+     values (on some systems).
+
+   * Remove support for non-`egcs' versions of `gcc'.
+
+   * Remove support for the `--driver' option, as `g77' now does all

+
+In 0.5.21:
+==========
+
+   * Fix a code-generation bug introduced by 0.5.20 caused by loop
+     unrolling (by specifying `-funroll-loops' or similar).  This bug
+     afflicted all code compiled by version 2.7.2.2.f.2 of `gcc' (C,
+     C++, Fortran, and so on).
+
+   * Fix a code-generation bug manifested when combining local
+     `EQUIVALENCE' with a `DATA' statement that follows the first
+     executable statement (or is treated as an executable-context
+     statement as a result of using the `-fpedantic' option).
+
+   * Fix a compiler crash that occured when an integer division by a
+     constant zero is detected.  Instead, when the `-W' option is
+     specified, the `gcc' back end issues a warning about such a case.
+     This bug afflicted all code compiled by version 2.7.2.2.f.2 of
+     `gcc' (C, C++, Fortran, and so on).
+
+   * Fix a compiler crash that occurred in some cases of procedure
+     inlining.  (Such cases became more frequent in 0.5.20.)
+
+   * Fix a compiler crash resulting from using `DATA' or similar to
+     initialize a `COMPLEX' variable or array to zero.
+
+   * Fix compiler crashes involving use of `AND', `OR', or `XOR'
+     intrinsics.
+
+   * Fix compiler bug triggered when using a `COMMON' or `EQUIVALENCE'
+     variable as the target of an `ASSIGN' or assigned-`GOTO' statement.
+
+   * Fix compiler crashes due to using the name of a some non-standard
+     intrinsics (such as `FTELL' or `FPUTC') as such and as the name of
+     a procedure or common block.  Such dual use of a name in a program
+     is allowed by the standard.
+
+   * Place automatic arrays on the stack, even if `SAVE' or the
+     `-fno-automatic' option is in effect.  This avoids a compiler
+     crash in some cases.
+
+   * The `-malign-double' option now reliably aligns `DOUBLE PRECISION'
+     optimally on Pentium and Pentium Pro architectures (586 and 686 in
+     `gcc').
+
+   * New option `-Wno-globals' disables warnings about "suspicious" use
+     of a name both as a global name and as the implicit name of an
+     intrinsic, and warnings about disagreements over the number or
+     natures of arguments passed to global procedures, or the natures
+     of the procedures themselves.
+
+     The default is to issue such warnings, which are new as of this
+     version of `g77'.
+
+   * New option `-fno-globals' disables diagnostics about potentially
+     fatal disagreements analysis problems, such as disagreements over
+     the number or natures of arguments passed to global procedures, or
+     the natures of those procedures themselves.
+
+     The default is to issue such diagnostics and flag the compilation
+     as unsuccessful.  With this option, the diagnostics are issued as
+     warnings, or, if `-Wno-globals' is specified, are not issued at
+     all.
+
+     This option also disables inlining of global procedures, to avoid
+     compiler crashes resulting from coding errors that these
+     diagnostics normally would identify.
+
+   * Diagnose cases where a reference to a procedure disagrees with the
+     type of that procedure, or where disagreements about the number or
+     nature of arguments exist.  This avoids a compiler crash.
+
+   * Fix parsing bug whereby `g77' rejected a second initialization
+     specification immediately following the first's closing `/' without
+     an intervening comma in a `DATA' statement, and the second
+     specification was an implied-DO list.
+
+   * Improve performance of the `gcc' back end so certain complicated
+     expressions involving `COMPLEX' arithmetic (especially
+     multiplication) don't appear to take forever to compile.
+
+   * Fix a couple of profiling-related bugs in `gcc' back end.
+
+   * Integrate GNU Ada's (GNAT's) changes to the back end, which
+     consist almost entirely of bug fixes.  These fixes are circa
+     version 3.10p of GNAT.
+
+   * Include some other `gcc' fixes that seem useful in `g77''s version
+     of `gcc'.  (See `gcc/ChangeLog' for details--compare it to that
+     file in the vanilla `gcc-2.7.2.3.tar.gz' distribution.)
+
+   * Fix `libU77' routines that accept file and other names to strip
+     trailing blanks from them, for consistency with other
+     implementations.  Blanks may be forcibly appended to such names by
+     appending a single null character (`CHAR(0)') to the significant
+     trailing blanks.
+
+   * Fix `CHMOD' intrinsic to work with file names that have embedded
+     blanks, commas, and so on.
+
+   * Fix `SIGNAL' intrinsic so it accepts an optional third `Status'
+     argument.
+
+   * Fix `IDATE()' intrinsic subroutine (VXT form) so it accepts
+     arguments in the correct order.  Documentation fixed accordingly,
+     and for `GMTIME()' and `LTIME()' as well.
+
+   * Make many changes to `libU77' intrinsics to support existing code
+     more directly.
+
+     Such changes include allowing both subroutine and function forms
+     of many routines, changing `MCLOCK()' and `TIME()' to return
+     `INTEGER(KIND=1)' values, introducing `MCLOCK8()' and `TIME8()' to
+     return `INTEGER(KIND=2)' values, and placing functions that are
+     intended to perform side effects in a new intrinsic group,
+     `badu77'.
+
+   * Improve `libU77' so it is more portable.
+
+   * Add options `-fbadu77-intrinsics-delete',
+     `-fbadu77-intrinsics-hide', and so on.
+
+   * Fix crashes involving diagnosed or invalid code.
+
+   * `g77' and `gcc' now do a somewhat better job detecting and
+     diagnosing arrays that are too large to handle before these cause
+     diagnostics during the assembler or linker phase, a compiler
+     crash, or generation of incorrect code.
+
+   * Make some fixes to alias analysis code.
+
+   * Add support for `restrict' keyword in `gcc' front end.
+
+   * Support `gcc' version 2.7.2.3 (modified by `g77' into version
+     2.7.2.3.f.1), and remove support for prior versions of `gcc'.
+
+   * Incorporate GNAT's patches to the `gcc' back end into `g77''s, so
+     GNAT users do not need to apply GNAT's patches to build both GNAT
+     and `g77' from the same source tree.
+
+   * Modify `make' rules and related code so that generation of Info
+     documentation doesn't require compilation using `gcc'.  Now, any
+     ANSI C compiler should be adequate to produce the `g77'
+     documentation (in particular, the tables of intrinsics) from
+     scratch.
+
+   * Add `INT2' and `INT8' intrinsics.
+
+   * Add `CPU_TIME' intrinsic.
+
+   * Add `ALARM' intrinsic.
+
+   * `CTIME' intrinsic now accepts any `INTEGER' argument, not just
+     `INTEGER(KIND=2)'.
+
+   * Warn when explicit type declaration disagrees with the type of an
+     intrinsic invocation.
+
+   * Support `*f771' entry in `gcc' `specs' file.
+
+   * Fix typo in `make' rule `g77-cross', used only for cross-compiling.
+
+   * Fix `libf2c' build procedure to re-archive library if previous
+     attempt to archive was interrupted.
+
+   * Change `gcc' to unroll loops only during the last invocation (of
+     as many as two invocations) of loop optimization.
+
+   * Improve handling of `-fno-f2c' so that code that attempts to pass
+     an intrinsic as an actual argument, such as `CALL FOO(ABS)', is
+     rejected due to the fact that the run-time-library routine is,
+     effectively, compiled with `-ff2c' in effect.
+
+   * Fix `g77' driver to recognize `-fsyntax-only' as an option that
+     inhibits linking, just like `-c' or `-S', and to recognize and
+     properly handle the `-nostdlib', `-M', `-MM', `-nodefaultlibs',
+     and `-Xlinker' options.
+
+   * Upgrade to `libf2c' as of 1997-08-16.
+
+   * Modify `libf2c' to consistently and clearly diagnose recursive I/O
+     (at run time).
+
+   * `g77' driver now prints version information (such as produced by
+     `g77 -v') to `stderr' instead of `stdout'.
+
+   * The `.r' suffix now designates a Ratfor source file, to be
+     preprocessed via the `ratfor' command, available separately.
+
+   * Fix some aspects of how `gcc' determines what kind of system is
+     being configured and what kinds are supported.  For example, GNU
+     Linux/Alpha ELF systems now are directly supported.
+
+   * Improve diagnostics.
+
+   * Improve documentation and indexing.
+
+   * Include all pertinent files for `libf2c' that come from
+     `netlib.bell-labs.com'; give any such files that aren't quite
+     accurate in `g77''s version of `libf2c' the suffix `.netlib'.
+
+   * Reserve `INTEGER(KIND=0)' for future use.
+
+In 0.5.20:
+==========
+
+   * The `-fno-typeless-boz' option is now the default.
+
+     This option specifies that non-decimal-radix constants using the
+     prefixed-radix form (such as `Z'1234'') are to be interpreted as
+     `INTEGER' constants.  Specify `-ftypeless-boz' to cause such
+     constants to be interpreted as typeless.
+
+     (Version 0.5.19 introduced `-fno-typeless-boz' and its inverse.)
+
+   * Options `-ff90-intrinsics-enable' and `-fvxt-intrinsics-enable'
+     now are the defaults.
+
+     Some programs might use names that clash with intrinsic names
+     defined (and now enabled) by these options or by the new `libU77'
+     intrinsics.  Users of such programs might need to compile them
+     differently (using, for example, `-ff90-intrinsics-disable') or,
+     better yet, insert appropriate `EXTERNAL' statements specifying
+     that these names are not intended to be names of intrinsics.
+
+   * The `ALWAYS_FLUSH' macro is no longer defined when building
+     `libf2c', which should result in improved I/O performance,
+     especially over NFS.
+
+     *Note:* If you have code that depends on the behavior of `libf2c'
+     when built with `ALWAYS_FLUSH' defined, you will have to modify
+     `libf2c' accordingly before building it from this and future
+     versions of `g77'.
+
+   * Dave Love's implementation of `libU77' has been added to the
+     version of `libf2c' distributed with and built as part of `g77'.
+     `g77' now knows about the routines in this library as intrinsics.
+
+   * New option `-fvxt' specifies that the source file is written in
+     VXT Fortran, instead of GNU Fortran.
+
+   * The `-fvxt-not-f90' option has been deleted, along with its
+     inverse, `-ff90-not-vxt'.
+
+     If you used one of these deleted options, you should re-read the
+     pertinent documentation to determine which options, if any, are
+     appropriate for compiling your code with this version of `g77'.
+
+   * The `-fugly' option now issues a warning, as it likely will be
+     removed in a future version.
+
+     (Enabling all the `-fugly-*' options is unlikely to be feasible,
+     or sensible, in the future, so users should learn to specify only
+     those `-fugly-*' options they really need for a particular source
+     file.)
+
+   * The `-fugly-assumed' option, introduced in version 0.5.19, has
+     been changed to better accommodate old and new code.
+
+   * Make a number of fixes to the `g77' front end and the `gcc' back
+     end to better support Alpha (AXP) machines.  This includes
+     providing at least one bug-fix to the `gcc' back end for Alphas.
+
+   * Related to supporting Alpha (AXP) machines, the `LOC()' intrinsic
+     and `%LOC()' construct now return values of integer type that is
+     the same width (holds the same number of bits) as the pointer type
+     on the machine.
+
+     On most machines, this won't make a difference, whereas on Alphas,
+     the type these constructs return is `INTEGER*8' instead of the
+     more common `INTEGER*4'.
+
+   * Emulate `COMPLEX' arithmetic in the `g77' front end, to avoid bugs
+     in `complex' support in the `gcc' back end.  New option
+     `-fno-emulate-complex' causes `g77' to revert the 0.5.19 behavior.
+
+   * Fix bug whereby `REAL A(1)', for example, caused a compiler crash
+     if `-fugly-assumed' was in effect and A was a local (automatic)
+     array.  That case is no longer affected by the new handling of
+     `-fugly-assumed'.
+
+   * Fix `g77' command driver so that `g77 -o foo.f' no longer deletes
+     `foo.f' before issuing other diagnostics, and so the `-x' option
+     is properly handled.
+
+   * Enable inlining of subroutines and functions by the `gcc' back end.
+     This works as it does for `gcc' itself--program units may be
+     inlined for invocations that follow them in the same program unit,
+     as long as the appropriate compile-time options are specified.
+
+   * Dummy arguments are no longer assumed to potentially alias
+     (overlap) other dummy arguments or `COMMON' areas when any of
+     these are defined (assigned to) by Fortran code.
+
+     This can result in faster and/or smaller programs when compiling
+     with optimization enabled, though on some systems this effect is
+     observed only when `-fforce-addr' also is specified.
+
+     New options `-falias-check', `-fargument-alias',
+     `-fargument-noalias', and `-fno-argument-noalias-global' control
+     the way `g77' handles potential aliasing.
+
+   * The `CONJG()' and `DCONJG()' intrinsics now are compiled in-line.
+
+   * The bug-fix for 0.5.19.1 has been re-done.  The `g77' compiler has
+     been changed back to assume `libf2c' has no aliasing problems in
+     its implementations of the `COMPLEX' (and `DOUBLE COMPLEX')
+     intrinsics.  The `libf2c' has been changed to have no such
+     problems.
+
+     As a result, 0.5.20 is expected to offer improved performance over
+     0.5.19.1, perhaps as good as 0.5.19 in most or all cases, due to
+     this change alone.
+
+     *Note:* This change requires version 0.5.20 of `libf2c', at least,
+     when linking code produced by any versions of `g77' other than
+     0.5.19.1.  Use `g77 -v' to determine the version numbers of the
+     `libF77', `libI77', and `libU77' components of the `libf2c'
+     library.  (If these version numbers are not printed--in
+     particular, if the linker complains about unresolved references to
+     names like `g77__fvers__'--that strongly suggests your
+     installation has an obsolete version of `libf2c'.)
+
+   * New option `-fugly-assign' specifies that the same memory
+     locations are to be used to hold the values assigned by both
+     statements `I = 3' and `ASSIGN 10 TO I', for example.  (Normally,
+     `g77' uses a separate memory location to hold assigned statement
+     labels.)
+
+   * `FORMAT' and `ENTRY' statements now are allowed to precede
+     `IMPLICIT NONE' statements.
+
+   * Produce diagnostic for unsupported `SELECT CASE' on `CHARACTER'
+     type, instead of crashing, at compile time.
+
+   * Fix crashes involving diagnosed or invalid code.
+
+   * Change approach to building `libf2c' archive (`libf2c.a') so that
+     members are added to it only when truly necessary, so the user
+     that installs an already-built `g77' doesn't need to have write
+     access to the build tree (whereas the user doing the build might
+     not have access to install new software on the system).
+
+   * Support `gcc' version 2.7.2.2 (modified by `g77' into version
+     2.7.2.2.f.2), and remove support for prior versions of `gcc'.
+
+   * Upgrade to `libf2c' as of 1997-02-08, and fix up some of the build
+     procedures.
+
+   * Improve general build procedures for `g77', fixing minor bugs
+     (such as deletion of any file named `f771' in the parent directory
+     of `gcc/').
+
+   * Enable full support of `INTEGER*8' available in `libf2c' and
+     `f2c.h' so that `f2c' users may make full use of its features via
+     the `g77' version of `f2c.h' and the `INTEGER*8' support routines
+     in the `g77' version of `libf2c'.
+
+   * Improve `g77' driver and `libf2c' so that `g77 -v' yields version
+     information on the library.
+
+   * The `SNGL' and `FLOAT' intrinsics now are specific intrinsics,
+     instead of synonyms for the generic intrinsic `REAL'.
+
+   * New intrinsics have been added.  These are `REALPART', `IMAGPART',
+     `COMPLEX', `LONG', and `SHORT'.
+
+   * A new group of intrinsics, `gnu', has been added to contain the
+     new `REALPART', `IMAGPART', and `COMPLEX' intrinsics.  An old
+     group, `dcp', has been removed.
+
+   * Complain about industry-wide ambiguous references `REAL(EXPR)' and
+     `AIMAG(EXPR)', where EXPR is `DOUBLE COMPLEX' (or any complex type
+     other than `COMPLEX'), unless `-ff90' option specifies Fortran 90
+     interpretation or new `-fugly-complex' option, in conjunction with
+     `-fnot-f90', specifies `f2c' interpretation.
+
+   * Make improvements to diagnostics.
+
+   * Speed up compiler a bit.
+
+   * Improvements to documentation and indexing, including a new
+     chapter containing information on one, later more, diagnostics
+     that users are directed to pull up automatically via a message in
+     the diagnostic itself.
+
+     (Hence the menu item `M' for the node `Diagnostics' in the
+     top-level menu of the Info documentation.)
+
+In 0.5.19.1:
+============
+
+   * Code-generation bugs afflicting operations on complex data have
+     been fixed.
+
+     These bugs occurred when assigning the result of an operation to a
+     complex variable (or array element) that also served as an input
+     to that operation.
+
+     The operations affected by this bug were: `CONJG()', `DCONJG()',
+     `CCOS()', `CDCOS()', `CLOG()', `CDLOG()', `CSIN()', `CDSIN()',
+     `CSQRT()', `CDSQRT()', complex division, and raising a `DOUBLE
+     COMPLEX' operand to an `INTEGER' power.  (The related generic and
+     `Z'-prefixed intrinsics, such as `ZSIN()', also were affected.)
+
+     For example, `C = CSQRT(C)', `Z = Z/C', and `Z = Z**I' (where `C'
+     is `COMPLEX' and `Z' is `DOUBLE COMPLEX') have been fixed.
+
+In 0.5.19:
+==========
+
+   * Fix `FORMAT' statement parsing so negative values for specifiers
+     such as `P' (e.g. `FORMAT(-1PF8.1)') are correctly processed as
+     negative.
+
+   * Fix `SIGNAL' intrinsic so it once again accepts a procedure as its
+     second argument.
+
+   * A temporary kludge option provides bare-bones information on
+     `COMMON' and `EQUIVALENCE' members at debug time.
+
+   * New `-fonetrip' option specifies FORTRAN-66-style one-trip `DO'
+     loops.
+
+   * New `-fno-silent' option causes names of program units to be
+     printed as they are compiled, in a fashion similar to UNIX `f77'
+     and `f2c'.
+
+   * New `-fugly-assumed' option specifies that arrays dimensioned via
+     `DIMENSION X(1)', for example, are to be treated as assumed-size.
+
+   * New `-fno-typeless-boz' option specifies that non-decimal-radix
+     constants using the prefixed-radix form (such as `Z'1234'') are to
+     be interpreted as `INTEGER' constants.
+
+   * New `-ff66' option is a "shorthand" option that specifies
+     behaviors considered appropriate for FORTRAN 66 programs.
+
+   * New `-ff77' option is a "shorthand" option that specifies
+     behaviors considered appropriate for UNIX `f77' programs.
+
+   * New `-fugly-comma' and `-fugly-logint' options provided to perform
+     some of what `-fugly' used to do.  `-fugly' and `-fno-ugly' are
+     now "shorthand" options, in that they do nothing more than enable
+     (or disable) other `-fugly-*' options.
+
+   * Fix parsing of assignment statements involving targets that are
+     substrings of elements of `CHARACTER' arrays having names such as
+     `READ', `WRITE', `GOTO', and `REALFUNCTIONFOO'.
+
+   * Fix crashes involving diagnosed code.
+
+   * Fix handling of local `EQUIVALENCE' areas so certain cases of
+     valid Fortran programs are not misdiagnosed as improperly
+     extending the area backwards.
+
+   * Support `gcc' version 2.7.2.1.
+
+   * Upgrade to `libf2c' as of 1996-09-26, and fix up some of the build
+     procedures.
+
+   * Change code generation for list-directed I/O so it allows for new
+     versions of `libf2c' that might return non-zero status codes for
+     some operations previously assumed to always return zero.
+
+     This change not only affects how `IOSTAT=' variables are set by
+     list-directed I/O, it also affects whether `END=' and `ERR='
+     labels are reached by these operations.
+
+   * Add intrinsic support for new `FTELL' and `FSEEK' procedures in
+     `libf2c'.
+
+   * Modify `fseek_()' in `libf2c' to be more portable (though, in
+     practice, there might be no systems where this matters) and to
+     catch invalid `whence' arguments.
+
+   * Some useless warnings from the `-Wunused' option have been
+     eliminated.
+
+   * Fix a problem building the `f771' executable on AIX systems by
+     linking with the `-bbigtoc' option.
+
+   * Abort configuration if `gcc' has not been patched using the patch
+     file provided in the `gcc/f/gbe/' subdirectory.
+
+   * Add options `--help' and `--version' to the `g77' command, to
+     conform to GNU coding guidelines.  Also add printing of `g77'
+     version number when the `--verbose' (`-v') option is used.
+
+   * Change internally generated name for local `EQUIVALENCE' areas to
+     one based on the alphabetically sorted first name in the list of
+     names for entities placed at the beginning of the areas.
+
+   * Improvements to documentation and indexing.
+
+In 0.5.18:
+==========
+
+   * Add some rudimentary support for `INTEGER*1', `INTEGER*2',
+     `INTEGER*8', and their `LOGICAL' equivalents.  (This support works
+     on most, maybe all, `gcc' targets.)
+
+     Thanks to Scott Snyder (<snyder@d0sgif.fnal.gov>) for providing
+     the patch for this!
+
+     Among the missing elements from the support for these features are
+     full intrinsic support and constants.
+
+   * Add some rudimentary support for the `BYTE' and `WORD'
+     type-declaration statements.  `BYTE' corresponds to `INTEGER*1',
+     while `WORD' corresponds to `INTEGER*2'.
+
+     Thanks to Scott Snyder (<snyder@d0sgif.fnal.gov>) for providing
+     the patch for this!
+
+   * The compiler code handling intrinsics has been largely rewritten
+     to accommodate the new types.  No new intrinsics or arguments for
+     existing intrinsics have been added, so there is, at this point,
+     no intrinsic to convert to `INTEGER*8', for example.
+
+   * Support automatic arrays in procedures.
+
+   * Reduce space/time requirements for handling large *sparsely*
+     initialized aggregate arrays.  This improvement applies to only a
+     subset of the general problem to be addressed in 0.6.
+
+   * Treat initial values of zero as if they weren't specified (in DATA
+     and type-declaration statements).  The initial values will be set
+     to zero anyway, but the amount of compile time processing them
+     will be reduced, in some cases significantly (though, again, this
+     is only a subset of the general problem to be addressed in 0.6).
+
+     A new option, `-fzeros', is introduced to enable the traditional
+     treatment of zeros as any other value.
+
+   * With `-ff90' in force, `g77' incorrectly interpreted `REAL(Z)' as
+     returning a `REAL' result, instead of as a `DOUBLE PRECISION'
+     result.  (Here, `Z' is `DOUBLE COMPLEX'.)
+
+     With `-fno-f90' in force, the interpretation remains unchanged,
+     since this appears to be how at least some F77 code using the
+     `DOUBLE COMPLEX' extension expected it to work.
+
+     Essentially, `REAL(Z)' in F90 is the same as `DBLE(Z)', while in
+     extended F77, it appears to be the same as `REAL(REAL(Z))'.
+
+   * An expression involving exponentiation, where both operands were
+     type `INTEGER' and the right-hand operand was negative, was
+     erroneously evaluated.
+
+   * Fix bugs involving `DATA' implied-`DO' constructs (these involved
+     an errant diagnostic and a crash, both on good code, one involving
+     subsequent statement-function definition).
+
+   * Close `INCLUDE' files after processing them, so compiling source
+     files with lots of `INCLUDE' statements does not result in being
+     unable to open `INCLUDE' files after all the available file
+     descriptors are used up.
+
+   * Speed up compiling, especially of larger programs, and perhaps
+     slightly reduce memory utilization while compiling (this is *not*
+     the improvement planned for 0.6 involving large aggregate
+     areas)--these improvements result from simply turning off some
+     low-level code to do self-checking that hasn't been triggered in a
+     long time.
+
+   * Introduce three new options that implement optimizations in the
+     `gcc' back end (GBE).  These options are `-fmove-all-movables',
+     `-freduce-all-givs', and `-frerun-loop-opt', which are enabled, by
+     default, for Fortran compilations.  These optimizations are
+     intended to help toon Fortran programs.
+
+   * Patch the GBE to do a better job optimizing certain kinds of
+     references to array elements.
+
+   * Due to patches to the GBE, the version number of `gcc' also is
+     patched to make it easier to manage installations, especially
+     useful if it turns out a `g77' change to the GBE has a bug.
+
+     The `g77'-modified version number is the `gcc' version number with
+     the string `.f.N' appended, where `f' identifies the version as
+     enhanced for Fortran, and N is `1' for the first Fortran patch for
+     that version of `gcc', `2' for the second, and so on.
+
+     So, this introduces version 2.7.2.f.1 of `gcc'.
+
+   * Make several improvements and fixes to diagnostics, including the
+     removal of two that were inappropriate or inadequate.
+
+   * Warning about two successive arithmetic operators, produced by
+     `-Wsurprising', now produced *only* when both operators are,
+     indeed, arithmetic (not relational/boolean).
+
+   * `-Wsurprising' now warns about the remaining cases of using
+     non-integral variables for implied-`DO' loops, instead of these
+     being rejected unless `-fpedantic' or `-fugly' specified.
+
+   * Allow `SAVE' of a local variable or array, even after it has been
+     given an initial value via `DATA', for example.
+
+   * Introduce an Info version of `g77' documentation, which supercedes
+     `gcc/f/CREDITS', `gcc/f/DOC', and `gcc/f/PROJECTS'.  These files
+     will be removed in a future release.  The files `gcc/f/BUGS',
+     `gcc/f/INSTALL', and `gcc/f/NEWS' now are automatically built from
+     the texinfo source when distributions are made.
+
+     This effort was inspired by a first pass at translating
+     `g77-0.5.16/f/DOC' that was contributed to Craig by David Ronis
+     (<ronis@onsager.chem.mcgill.ca>).
+
+   * New `-fno-second-underscore' option to specify that, when
+     `-funderscoring' is in effect, a second underscore is not to be
+     appended to Fortran names already containing an underscore.
+
+   * Change the way iterative `DO' loops work to follow the F90
+     standard.  In particular, calculation of the iteration count is
+     still done by converting the start, end, and increment parameters
+     to the type of the `DO' variable, but the result of the
+     calculation is always converted to the default `INTEGER' type.
+
+     (This should have no effect on existing code compiled by `g77',
+     but code written to assume that use of a *wider* type for the `DO'
+     variable will result in an iteration count being fully calculated
+     using that wider type (wider than default `INTEGER') must be
+     rewritten.)
+
+   * Support `gcc' version 2.7.2.
+
+   * Upgrade to `libf2c' as of 1996-03-23, and fix up some of the build
+     procedures.
+
+     Note that the email addresses related to `f2c' have changed--the
+     distribution site now is named `netlib.bell-labs.com', and the
+     maintainer's new address is <dmg@bell-labs.com>.
+
+In 0.5.17:
+==========
+
+   * *Fix serious bug* in `g77 -v' command that can cause removal of a
+     system's `/dev/null' special file if run by user `root'.
+
+     *All users* of version 0.5.16 should ensure that they have not
+     removed `/dev/null' or replaced it with an ordinary file (e.g. by
+     comparing the output of `ls -l /dev/null' with `ls -l /dev/zero'.
+     If the output isn't basically the same, contact your system
+     administrator about restoring `/dev/null' to its proper status).
+
+     This bug is particularly insidious because removing `/dev/null' as
+     a special file can go undetected for quite a while, aside from
+     various applications and programs exhibiting sudden, strange
+     behaviors.
+
+     I sincerely apologize for not realizing the implications of the
+     fact that when `g77 -v' runs the `ld' command with `-o /dev/null'
+     that `ld' tries to *remove* the executable it is supposed to build
+     (especially if it reports unresolved references, which it should
+     in this case)!
+
+   * Fix crash on `CHARACTER*(*) FOO' in a main or block data program
+     unit.
+
+   * Fix crash that can occur when diagnostics given outside of any
+     program unit (such as when input file contains `@foo').
+
+   * Fix crashes, infinite loops (hangs), and such involving diagnosed
+     code.
+
+   * Fix `ASSIGN''ed variables so they can be `SAVE''d or dummy
+     arguments, and issue clearer error message in cases where target
+     of `ASSIGN' or `ASSIGN'ed `GOTO'/`FORMAT' is too small (which
+     should never happen).
+
+   * Make `libf2c' build procedures work on more systems again by
+     eliminating unnecessary invocations of `ld -r -x' and `mv'.
+
+   * Fix omission of `-funix-intrinsics-...' options in list of
+     permitted options to compiler.
+
+   * Fix failure to always diagnose missing type declaration for
+     `IMPLICIT NONE'.
+
+   * Fix compile-time performance problem (which could sometimes crash
+     the compiler, cause a hang, or whatever, due to a bug in the back
+     end) involving exponentiation with a large `INTEGER' constant for
+     the right-hand operator (e.g. `I**32767').
+
+   * Fix build procedures so cross-compiling `g77' (the `fini' utility
+     in particular) is properly built using the host compiler.
+
+   * Add new `-Wsurprising' option to warn about constructs that are
+     interpreted by the Fortran standard (and `g77') in ways that are
+     surprising to many programmers.
+
+   * Add `ERF()' and `ERFC()' as generic intrinsics mapping to existing
+     `ERF'/`DERF' and `ERFC'/`DERFC' specific intrinsics.
+
+     *Note:* You should specify `INTRINSIC ERF,ERFC' in any code where
+     you might use these as generic intrinsics, to improve likelihood
+     of diagnostics (instead of subtle run-time bugs) when using a
+     compiler that doesn't support these as intrinsics (e.g. `f2c').
+
+   * Remove from `-fno-pedantic' the diagnostic about `DO' with
+     non-`INTEGER' index variable; issue that under `-Wsurprising'
+     instead.
+
+   * Clarify some diagnostics that say things like "ignored" when that's
+     misleading.
+
+   * Clarify diagnostic on use of `.EQ.'/`.NE.' on `LOGICAL' operands.
+
+   * Minor improvements to code generation for various operations on
+     `LOGICAL' operands.
+
+   * Minor improvement to code generation for some `DO' loops on some
+     machines.
+
+   * Support `gcc' version 2.7.1.
+
+   * Upgrade to `libf2c' as of 1995-11-15.
+
+In 0.5.16:
+==========
+
+   * Fix a code-generation bug involving complicated `EQUIVALENCE'
+     statements not involving `COMMON'.
+
+   * Fix code-generation bugs involving invoking "gratis" library
+     procedures in `libf2c' from code compiled with `-fno-f2c' by
+     making these procedures known to `g77' as intrinsics (not affected
+     by -fno-f2c).  This is known to fix code invoking `ERF()',
+     `ERFC()', `DERF()', and `DERFC()'.
+
+   * Update `libf2c' to include netlib patches through 1995-08-16, and
+     `#define' `WANT_LEAD_0' to 1 to make `g77'-compiled code more
+     consistent with other Fortran implementations by outputting
+     leading zeros in formatted and list-directed output.
+
+   * Fix a code-generation bug involving adjustable dummy arrays with
+     high bounds whose primaries are changed during procedure
+     execution, and which might well improve code-generation
+     performance for such arrays compared to `f2c' plus `gcc' (but
+     apparently only when using `gcc-2.7.0' or later).
+
+   * Fix a code-generation bug involving invocation of `COMPLEX' and
+     `DOUBLE COMPLEX' `FUNCTION's and doing `COMPLEX' and `DOUBLE
+     COMPLEX' divides, when the result of the invocation or divide is
+     assigned directly to a variable that overlaps one or more of the
+     arguments to the invocation or divide.
+
+   * Fix crash by not generating new optimal code for `X**I' if `I' is
+     nonconstant and the expression is used to dimension a dummy array,
+     since the `gcc' back end does not support the necessary mechanics
+     (and the `gcc' front end rejects the equivalent construct, as it
+     turns out).
+
+   * Fix crash on expressions like `COMPLEX**INTEGER'.
+
+   * Fix crash on expressions like `(1D0,2D0)**2', i.e. raising a
+     `DOUBLE COMPLEX' constant to an `INTEGER' constant power.
+
+   * Fix crashes and such involving diagnosed code.
+
+   * Diagnose, instead of crashing on, statement function definitions
+     having duplicate dummy argument names.
+
+   * Fix bug causing rejection of good code involving statement function
+     definitions.
+
+   * Fix bug resulting in debugger not knowing size of local equivalence
+     area when any member of area has initial value (via `DATA', for
+     example).
+
+   * Fix installation bug that prevented installation of `g77' driver.
+     Provide for easy selection of whether to install copy of `g77' as
+     `f77' to replace the broken code.
+
+   * Fix `gcc' driver (affects `g77' thereby) to not gratuitously
+     invoke the `f771' program (e.g. when `-E' is specified).
+
+   * Fix diagnostic to point to correct source line when it immediately
+     follows an `INCLUDE' statement.
+
+   * Support more compiler options in `gcc'/`g77' when compiling
+     Fortran files.  These options include `-p', `-pg', `-aux-info',
+     `-P', correct setting of version-number macros for preprocessing,
+     full recognition of `-O0', and automatic insertion of
+     configuration-specific linker specs.
+
+   * Add new intrinsics that interface to existing routines in `libf2c':
+     `ABORT', `DERF', `DERFC', `ERF', `ERFC', `EXIT', `FLUSH',
+     `GETARG', `GETENV', `IARGC', `SIGNAL', and `SYSTEM'.  Note that
+     `ABORT', `EXIT', `FLUSH', `SIGNAL', and `SYSTEM' are intrinsic
+     subroutines, not functions (since they have side effects), so to
+     get the return values from `SIGNAL' and `SYSTEM', append a final
+     argument specifying an `INTEGER' variable or array element (e.g.
+     `CALL SYSTEM('rm foo',ISTAT)').
+
+   * Add new intrinsic group named `unix' to contain the new intrinsics,
+     and by default enable this new group.
+
+   * Move `LOC()' intrinsic out of the `vxt' group to the new `unix'
+     group.
+
+   * Improve `g77' so that `g77 -v' by itself (or with certain other
+     options, including `-B', `-b', `-i', `-nostdlib', and `-V')
+     reports lots more useful version info, and so that long-form
+     options `gcc' accepts are understood by `g77' as well (even in
+     truncated, unambiguous forms).
+
+   * Add new `g77' option `--driver=name' to specify driver when
+     default, `gcc', isn't appropriate.
+
+   * Add support for `#' directives (as output by the preprocessor) in
+     the compiler, and enable generation of those directives by the
+     preprocessor (when compiling `.F' files) so diagnostics and
+     debugging info are more useful to users of the preprocessor.
+
+   * Produce better diagnostics, more like `gcc', with info such as `In
+     function `foo':' and `In file included from...:'.
+
+   * Support `gcc''s `-fident' and `-fno-ident' options.
+
+   * When `-Wunused' in effect, don't warn about local variables used as
+     statement-function dummy arguments or `DATA' implied-`DO' iteration
+     variables, even though, strictly speaking, these are not uses of
+     the variables themselves.
+
+   * When `-W -Wunused' in effect, don't warn about unused dummy
+     arguments at all, since there's no way to turn this off for
+     individual cases (`g77' might someday start warning about
+     these)--applies to `gcc' versions 2.7.0 and later, since earlier
+     versions didn't warn about unused dummy arguments.
+
+   * New option `-fno-underscoring' that inhibits transformation of
+     names (by appending one or two underscores) so users may experiment
+     with implications of such an environment.
+
+   * Minor improvement to `gcc/f/info' module to make it easier to build
+     `g77' using the native (non-`gcc') compiler on certain machines
+     (but definitely not all machines nor all non-`gcc' compilers).
+     Please do not report bugs showing problems compilers have with
+     macros defined in `gcc/f/target.h' and used in places like
+     `gcc/f/expr.c'.
+
+   * Add warning to be printed for each invocation of the compiler if
+     the target machine `INTEGER', `REAL', or `LOGICAL' size is not 32
+     bits, since `g77' is known to not work well for such cases (to be
+     fixed in Version 0.6--*note Actual Bugs We Haven't Fixed Yet:
+     Actual Bugs.).
+
+   * Lots of new documentation (though work is still needed to put it
+     into canonical GNU format).
+
+   * Build `libf2c' with `-g0', not `-g2', in effect (by default), to
+     produce smaller library without lots of debugging clutter.
+
+In 0.5.15:
+==========
+
+   * Fix bad code generation involving `X**I' and temporary, internal
+     variables generated by `g77' and the back end (such as for `DO'
+     loops).
+
+   * Fix crash given `CHARACTER A;DATA A/.TRUE./'.
+
+   * Replace crash with diagnostic given `CHARACTER A;DATA A/1.0/'.
+
+   * Fix crash or other erratic behavior when null character constant
+     (`''') is encountered.
+
+   * Fix crash or other erratic behavior involving diagnosed code.
+
+   * Fix code generation for external functions returning type `REAL'
+     when the `-ff2c' option is in force (which it is by default) so
+     that `f2c' compatibility is indeed provided.
+
+   * Disallow `COMMON I(10)' if `I' has previously been specified with
+     an array declarator.
+
+   * New `-ffixed-line-length-N' option, where N is the maximum length
+     of a typical fixed-form line, defaulting to 72 columns, such that
+     characters beyond column N are ignored, or N is `none', meaning no
+     characters are ignored.  does not affect lines with `&' in column
+     1, which are always processed as if `-ffixed-line-length-none' was
+     in effect.
+
+   * No longer generate better code for some kinds of array references,
+     as `gcc' back end is to be fixed to do this even better, and it
+     turned out to slow down some code in some cases after all.
+
+   * In `COMMON' and `EQUIVALENCE' areas with any members given initial
+     values (e.g. via `DATA'), uninitialized members now always
+     initialized to binary zeros (though this is not required by the
+     standard, and might not be done in future versions of `g77').
+     Previously, in some `COMMON'/`EQUIVALENCE' areas (essentially
+     those with members of more than one type), the uninitialized
+     members were initialized to spaces, to cater to `CHARACTER' types,
+     but it seems no existing code expects that, while much existing
+     code expects binary zeros.
+
+In 0.5.14:
+==========
+
+   * Don't emit bad code when low bound of adjustable array is
+     nonconstant and thus might vary as an expression at run time.
+
+   * Emit correct code for calculation of number of trips in `DO' loops
+     for cases where the loop should not execute at all.  (This bug
+     affected cases where the difference between the begin and end
+     values was less than the step count, though probably not for
+     floating-point cases.)
+
+   * Fix crash when extra parentheses surround item in `DATA'
+     implied-`DO' list.
+
+   * Fix crash over minor internal inconsistencies in handling
+     diagnostics, just substitute dummy strings where necessary.
+
+   * Fix crash on some systems when compiling call to `MVBITS()'
+     intrinsic.
+
+   * Fix crash on array assignment `TYPEDDD(...)=...', where DDD is a
+     string of one or more digits.
+
+   * Fix crash on `DCMPLX()' with a single `INTEGER' argument.
+
+   * Fix various crashes involving code with diagnosed errors.
+
+   * Support `-I' option for `INCLUDE' statement, plus `gcc''s
+     `header.gcc' facility for handling systems like MS-DOS.
+
+   * Allow `INCLUDE' statement to be continued across multiple lines,
+     even allow it to coexist with other statements on the same line.
+
+   * Incorporate Bellcore fixes to `libf2c' through 1995-03-15--this
+     fixes a bug involving infinite loops reading EOF with empty
+     list-directed I/O list.
+
+   * Remove all the `g77'-specific auto-configuration scripts, code,
+     and so on, except for temporary substitutes for bsearch() and
+     strtoul(), as too many configure/build problems were reported in
+     these areas.  People will have to fix their systems' problems
+     themselves, or at least somewhere other than `g77', which expects
+     a working ANSI C environment (and, for now, a GNU C compiler to
+     compile `g77' itself).
+
+   * Complain if initialized common redeclared as larger in subsequent
+     program unit.
+
+   * Warn if blank common initialized, since its size can vary and hence
+     related warnings that might be helpful won't be seen.
+
+   * New `-fbackslash' option, on by default, that causes `\' within
+     `CHARACTER' and Hollerith constants to be interpreted a la GNU C.
+     Note that this behavior is somewhat different from `f2c''s, which
+     supports only a limited subset of backslash (escape) sequences.
+
+   * Make `-fugly-args' the default.
+
+   * New `-fugly-init' option, on by default, that allows
+     typeless/Hollerith to be specified as initial values for variables
+     or named constants (`PARAMETER'), and also allows
+     character<->numeric conversion in those contexts--turn off via
+     `-fno-ugly-init'.
+
+   * New `-finit-local-zero' option to initialize local variables to
+     binary zeros.  This does not affect whether they are `SAVE'd, i.e.
+     made automatic or static.
+
+   * New `-Wimplicit' option to warn about implicitly typed variables,
+     arrays, and functions.  (Basically causes all program units to
+     default to `IMPLICIT NONE'.)
+
+   * `-Wall' now implies `-Wuninitialized' as with `gcc' (i.e. unless
+     `-O' not specified, since `-Wuninitialized' requires `-O'), and
+     implies `-Wunused' as well.
+
+   * `-Wunused' no longer gives spurious messages for unused `EXTERNAL'
+     names (since they are assumed to refer to block data program
+     units, to make use of libraries more reliable).
+
+   * Support `%LOC()' and `LOC()' of character arguments.
+
+   * Support null (zero-length) character constants and expressions.
+
+   * Support `f2c''s `IMAG()' generic intrinsic.
+
+   * Support `ICHAR()', `IACHAR()', and `LEN()' of character
+     expressions that are valid in assignments but not normally as
+     actual arguments.
+
+   * Support `f2c'-style `&' in column 1 to mean continuation line.
+
+   * Allow `NAMELIST', `EXTERNAL', `INTRINSIC', and `VOLATILE' in
+     `BLOCK DATA', even though these are not allowed by the standard.
+
+   * Allow `RETURN' in main program unit.
+
+   * Changes to Hollerith-constant support to obey Appendix C of the
+     standard:
+
+        - Now padded on the right with zeros, not spaces.
+
+        - Hollerith "format specifications" in the form of arrays of
+          non-character allowed.
+
+        - Warnings issued when non-space truncation occurs when
+          converting to another type.
+
+        - When specified as actual argument, now passed by reference to
+          `INTEGER' (padded on right with spaces if constant too small,
+          otherwise fully intact if constant wider the `INTEGER' type)
+          instead of by value.
+
+     *Warning:* `f2c' differs on the interpretation of `CALL FOO(1HX)',
+     which it treats exactly the same as `CALL FOO('X')', but which the
+     standard and `g77' treat as `CALL FOO(%REF('X   '))' (padded with
+     as many spaces as necessary to widen to `INTEGER'), essentially.
+
+   * Changes and fixes to typeless-constant support:
+
+        - Now treated as a typeless double-length `INTEGER' value.
+
+        - Warnings issued when overflow occurs.
+
+        - Padded on the left with zeros when converting to a larger
+          type.
+
+        - Should be properly aligned and ordered on the target machine
+          for whatever type it is turned into.
+
+        - When specified as actual argument, now passed as reference to
+          a default `INTEGER' constant.
+
+   * `%DESCR()' of a non-`CHARACTER' expression now passes a pointer to
+     the expression plus a length for the expression just as if it were
+     a `CHARACTER' expression.  For example, `CALL FOO(%DESCR(D))',
+     where `D' is `REAL*8', is the same as `CALL FOO(D,%VAL(8)))'.
+
+   * Name of multi-entrypoint master function changed to incorporate
+     the name of the primary entry point instead of a decimal value, so
+     the name of the master function for `SUBROUTINE X' with alternate
+     entry points is now `__g77_masterfun_x'.
+
+   * Remove redundant message about zero-step-count `DO' loops.
+
+   * Clean up diagnostic messages, shortening many of them.
+
+   * Fix typo in `g77' man page.
+
+   * Clarify implications of constant-handling bugs in `f/BUGS'.
+
+   * Generate better code for `**' operator with a right-hand operand of
+     type `INTEGER'.
+
+   * Generate better code for `SQRT()' and `DSQRT()', also when
+     `-ffast-math' specified, enable better code generation for `SIN()'
+     and `COS()'.
+
+   * Generate better code for some kinds of array references.
+
+   * Speed up lexing somewhat (this makes the compilation phase
+     noticeably faster).

+of @code{g77}.
+This includes bugs that are actually in the @code{gcc}

+of (and necessarily intertwined with) @code{g77},

+
+@itemize @bullet
+@item
+@code{g77} generates bad code for assignments,
+or other conversions,
+of @code{REAL} or @code{COMPLEX} constant expressions
+to type @code{INTEGER(KIND=2)}
+(often referred to as @code{INTEGER*8}).
+
+For example, @samp{INTEGER*8 J; J = 4E10} is miscompiled
+on some systems---the wrong value is stored in @var{J}.
+
+@item
+The @code{IDate} Intrinsic (VXT)
+fails to return the year in the documented, non-Y2K-compliant range
+of 0--99,
+instead returning 100 for the year 2000.
+
+@c Fixed in @code{egcs} 1.2.
+
+@item
+Year 2000 (Y2K) compliance information
+is missing from the documentation.
+
+@c Fixed in @code{egcs} 1.2.
+
+@item
+@code{g77} crashes when compiling
+I/O statements using keywords that define @code{INTEGER} values,
+such as @samp{IOSTAT=@var{j}},
+where @var{j} is other than default @code{INTEGER}
+(such as @code{INTEGER*2}).
+
+@c Fixed in @code{egcs} 1.2.
+
+@item
+The @samp{-ax} option is not obeyed when compiling Fortran programs.
+(It is not passed to the @file{f771} driver.)
+
+@c Fixed in @code{egcs} 1.2.
+
+@item
+@code{g77} fails to warn about a reference to a function
+when the corresponding @emph{subsequent} function program unit
+disagrees with the reference concerning the type of the function.
+
+@c Fixed in @code{egcs} 1.2.
+
+@item
+@c Tim Prince discovered this.
+Automatic arrays possibly aren't working on HP-UX systems,
+at least in HP-UX version 10.20.
+Writing into them apparently causes over-writing
+of statically declared data in the main program.
+This probably means the arrays themselves are being under-allocated,
+or pointers to them being improperly handled,
+e.g. not passed to other procedures as they should be.
+
+@item
+@code{g77} fails to warn about
+use of a ``live'' iterative-DO variable
+as an implied-DO variable
+in a @samp{WRITE} or @samp{PRINT} statement
+(although it does warn about this in a @samp{READ} statement).
+
+@item
+Something about @code{g77}'s straightforward handling of
+label references and definitions sometimes prevents the GBE
+from unrolling loops.
+Until this is solved, try inserting or removing @code{CONTINUE}
+statements as the terminal statement, using the @code{END DO}
+form instead, and so on.
+
+@item
+Some confusion in diagnostics concerning failing @code{INCLUDE}
+statements from within @code{INCLUDE}'d or @code{#include}'d files.
+
+@cindex integer constants
+@cindex constants, integer
+@item
+@code{g77} assumes that @code{INTEGER(KIND=1)} constants range
+from @samp{-2**31} to @samp{2**31-1} (the range for
+two's-complement 32-bit values),
+instead of determining their range from the actual range of the
+type for the configuration (and, someday, for the constant).
+
+Further, it generally doesn't implement the handling
+of constants very well in that it makes assumptions about the
+configuration that it no longer makes regarding variables (types).
+
+Included with this item is the fact that @code{g77} doesn't recognize
+that, on IEEE-754/854-compliant systems, @samp{0./0.} should produce a NaN
+and no warning instead of the value @samp{0.} and a warning.
+This is to be fixed in version 0.6, when @code{g77} will use the
+@code{gcc} back end's constant-handling mechanisms to replace its own.
+
+@cindex compiler speed
+@cindex speed, of compiler
+@cindex compiler memory usage
+@cindex memory usage, of compiler
+@cindex large aggregate areas
+@cindex initialization
+@cindex DATA statement
+@cindex statements, DATA
+@item
+@code{g77} uses way too much memory and CPU time to process large aggregate
+areas having any initialized elements.
+
+For example, @samp{REAL A(1000000)} followed by @samp{DATA A(1)/1/}
+takes up way too much time and space, including
+the size of the generated assembler file.
+This is to be mitigated somewhat in version 0.6.
+
+Version 0.5.18 improves cases like this---specifically,
+cases of @emph{sparse} initialization that leave large, contiguous
+areas uninitialized---significantly.
+However, even with the improvements, these cases still
+require too much memory and CPU time.
+
+(Version 0.5.18 also improves cases where the initial values are
+zero to a much greater degree, so if the above example
+ends with @samp{DATA A(1)/0/}, the compile-time performance
+will be about as good as it will ever get, aside from unrelated
+improvements to the compiler.)
+
+Note that @code{g77} does display a warning message to
+notify the user before the compiler appears to hang.
+@ifset last-up-date
+@xref{Large Initialization,,Initialization of Large Aggregate Areas},
+for information on how to change the point at which
+@code{g77} decides to issue this warning.
+@end ifset
+
+@cindex debugging
+@cindex common blocks
+@cindex equivalence areas
+@cindex local equivalence areas
+@item
+@code{g77} doesn't emit variable and array members of common blocks for use
+with a debugger (the @samp{-g} command-line option).
+The code is present to do this, but doesn't work with at least
+one debug format---perhaps it works with others.
+And it turns out there's a similar bug for
+local equivalence areas, so that has been disabled as well.
+
+As of Version 0.5.19, a temporary kludge solution is provided whereby
+some rudimentary information on a member is written as a string that
+is the member's value as a character string.

+@ifset last-up-date

+
+@cindex code, displaying main source
+@cindex displaying main source code
+@cindex debugging main source code
+@cindex printing main source
+@item
+When debugging, after starting up the debugger but before being able
+to see the source code for the main program unit, the user must currently
+set a breakpoint at @samp{MAIN__} (or @samp{MAIN___} or @samp{MAIN_} if
+@samp{MAIN__} doesn't exist)
+and run the program until it hits the breakpoint.
+At that point, the
+main program unit is activated and about to execute its first
+executable statement, but that's the state in which the debugger should
+start up, as is the case for languages like C.
+
+@cindex debugger
+@item
+Debugging @code{g77}-compiled code using debuggers other than
+@code{gdb} is likely not to work.
+
+Getting @code{g77} and @code{gdb} to work together is a known
+problem---getting @code{g77} to work properly with other
+debuggers, for which source code often is unavailable to @code{g77}
+developers, seems like a much larger, unknown problem,
+and is a lower priority than making @code{g77} and @code{gdb}
+work together properly.
+
+On the other hand, information about problems other debuggers
+have with @code{g77} output might make it easier to properly
+fix @code{g77}, and perhaps even improve @code{gdb}, so it
+is definitely welcome.
+Such information might even lead to all relevant products
+working together properly sooner.
+
+@cindex Alpha, support
+@cindex support, Alpha
+@item
+@code{g77} doesn't work perfectly on 64-bit configurations
+such as the Digital Semiconductor (``DEC'') Alpha.
+
+This problem is largely resolved as of version 0.5.23.
+Version 0.6 should solve most or all remaining problems
+(such as cross-compiling involving 64-bit machines).
+
+@cindex COMPLEX support
+@cindex support, COMPLEX
+@item
+Maintainers of gcc report that the back end definitely has ``broken''
+support for @code{COMPLEX} types.
+Based on their input, it seems many of
+the problems affect only the more-general facilities for gcc's
+@code{__complex__} type, such as @code{__complex__ int}
+(where the real and imaginary parts are integers) that GNU
+Fortran does not use.
+
+Version 0.5.20 of @code{g77} works around this
+problem by not using the back end's support for @code{COMPLEX}.
+The new option @samp{-fno-emulate-complex} avoids the work-around,
+reverting to using the same ``broken'' mechanism as that used
+by versions of @code{g77} prior to 0.5.20.
+
+@cindex padding
+@cindex structures
+@cindex common blocks
+@cindex equivalence areas
+@item
+@code{g77} currently inserts needless padding for things like
+@samp{COMMON A,IPAD} where @samp{A} is @code{CHARACTER*1} and @samp{IPAD}
+is @code{INTEGER(KIND=1)} on machines like x86,
+because the back end insists that @samp{IPAD}
+be aligned to a 4-byte boundary,
+but the processor has no such requirement
+(though it is usually good for performance).
+
+The @code{gcc} back end needs to provide a wider array
+of specifications of alignment requirements and preferences for targets,
+and front ends like @code{g77} should take advantage of this
+when it becomes available.
+
+@cindex alignment
+@cindex double-precision performance
+@cindex -malign-double
+@item
+The x86 target's @samp{-malign-double} option
+no longer reliably aligns double-precision variables and arrays
+when they are placed in the stack frame.
+
+This can significantly reduce the performance of some applications,
+even on a run-to-run basis
+(that is, performance measurements can vary fairly widely
+depending on whether frequently used variables are properly aligned,
+and that can change from one program run to the next,
+even from one procedure call to the next).
+
+Versions 0.5.22 and earlier of @code{g77}
+included a patch to @code{gcc} that enabled this,
+but that patch has been deemed an improper (probably buggy) one
+for version 2.8 of @code{gcc} and for @code{egcs}.
+
+Note that version 1.1 of @code{egcs}
+aligns double-precision variables and arrays
+when they are in static storage
+even if @samp{-malign-double} is not specified.
+
+There is ongoing investigation into
+how to make @samp{-malign-double} work properly,
+also into how to make it unnecessary to get
+all double-precision variables and arrays aligned
+when such alignment would not violate
+the relevant specifications for processor
+and inter-procedural interfaces.
+
+For a suite of programs to test double-precision alignment,
+see @uref{ftp://alpha.gnu.org/gnu/g77/align/}.
+
+@cindex complex performance
+@cindex aliasing
+@item
+The @code{libf2c} routines that perform some run-time
+arithmetic on @code{COMPLEX} operands
+were modified circa version 0.5.20 of @code{g77}
+to work properly even in the presence of aliased operands.
+
+While the @code{g77} and @code{netlib} versions of @code{libf2c}
+differ on how this is accomplished,
+the main differences are that we believe
+the @code{g77} version works properly
+even in the presence of @emph{partially} aliased operands.
+
+However, these modifications have reduced performance
+on targets such as x86,
+due to the extra copies of operands involved.

+/* Understanding this module means understanding the interface between
+   the g77 front end and the gcc back end (or, perhaps, some other
+   back end).  In here are the functions called by the front end proper
+   to notify whatever back end is in place about certain things, and
+   also the back-end-specific functions.  It's a bear to deal with, so
+   lately I've been trying to simplify things, especially with regard
+   to the gcc-back-end-specific stuff.
+
+   Building expressions generally seems quite easy, but building decls
+   has been challenging and is undergoing revision.  gcc has several
+   kinds of decls:
+
+   TYPE_DECL -- a type (int, float, struct, function, etc.)
+   CONST_DECL -- a constant of some type other than function
+   LABEL_DECL -- a variable or a constant?
+   PARM_DECL -- an argument to a function (a variable that is a dummy)
+   RESULT_DECL -- the return value of a function (a variable)
+   VAR_DECL -- other variable (can hold a ptr-to-function, struct, int, etc.)
+   FUNCTION_DECL -- a function (either the actual function or an extern ref)
+   FIELD_DECL -- a field in a struct or union (goes into types)
+
+   g77 has a set of functions that somewhat parallels the gcc front end
+   when it comes to building decls:
+
+   Internal Function (one we define, not just declare as extern):
+   int yes;
+   yes = suspend_momentary ();
+   if (is_nested) push_f_function_context ();
+   start_function (get_identifier ("function_name"), function_type,
+		   is_nested, is_public);
+   // for each arg, build PARM_DECL and call push_parm_decl (decl) with it;
+   store_parm_decls (is_main_program);
+   ffecom_start_compstmt_ ();
+   // for stmts and decls inside function, do appropriate things;
+   ffecom_end_compstmt_ ();
+   finish_function (is_nested);
+   if (is_nested) pop_f_function_context ();
+   if (is_nested) resume_momentary (yes);
+
+   Everything Else:
+   int yes;
+   tree d;
+   tree init;
+   yes = suspend_momentary ();
+   // fill in external, public, static, &c for decl, and
+   // set DECL_INITIAL to error_mark_node if going to initialize
+   // set is_top_level TRUE only if not at top level and decl

+		   variable_size to wrap SAVE_EXPR's around expressions
+		   affecting the size/shape of an array so that the
+		   size/shape info doesn't change during execution
+		   of the compiled code even though variables and
+		   functions referenced in those expressions might.
+
+		   variable_size also makes sure those saved expressions
+		   get evaluated immediately upon entry to the
+		   compiled procedure -- the front end normally doesn't
+		   have to worry about that.
+
+		   However, there is a problem with this that affects
+		   g77's implementation of entry points, and that is
+		   that it is _not_ true that each invocation of the
+		   compiled procedure is permitted to evaluate
+		   array size/shape info -- because it is possible
+		   that, for some invocations, that info is invalid (in
+		   which case it is "promised" -- i.e. a violation of
+		   the Fortran standard -- that the compiled code
+		   won't reference the array or its size/shape
+		   during that particular invocation).
+
+		   To phrase this in C terms, consider this gcc function:
+
+		     void foo (int *n, float (*a)[*n])
+		     {
+		       // a is "pointer to array ...", fyi.
+		     }
+
+		   Suppose that, for some invocations, it is permitted
+		   for a caller of foo to do this:
+
+		       foo (NULL, NULL);
+
+		   Now the _written_ code for foo can take such a call
+		   into account by either testing explicitly for whether
+		   (a == NULL) || (n == NULL) -- presumably it is
+		   not permitted to reference *a in various fashions
+		   if (n == NULL) I suppose -- or it can avoid it by
+		   looking at other info (other arguments, static/global
+		   data, etc.).
+
+		   However, this won't work in gcc 2.5.8 because it'll
+		   automatically emit the code to save the "*n"
+		   expression, which'll yield a NULL dereference for
+		   the "foo (NULL, NULL)" call, something the code
+		   for foo cannot prevent.
+
+		   g77 definitely needs to avoid executing such
+		   code anytime the pointer to the adjustable array
+		   is NULL, because even if its bounds expressions
+		   don't have any references to possible "absent"
+		   variables like "*n" -- say all variable references
+		   are to COMMON variables, i.e. global (though in C,
+		   local static could actually make sense) -- the
+		   expressions could yield other run-time problems
+		   for allowably "dead" values in those variables.
+
+		   For example, let's consider a more complicated
+		   version of foo:
+
+		     extern int i;
+		     extern int j;
+
+		     void foo (float (*a)[i/j])
+		     {
+		       ...
+		     }
+
+		   The above is (essentially) quite valid for Fortran
+		   but, again, for a call like "foo (NULL);", it is
+		   permitted for i and j to be undefined when the
+		   call is made.  If j happened to be zero, for
+		   example, emitting the code to evaluate "i/j"
+		   could result in a run-time error.
+
+		   Offhand, though I don't have my F77 or F90
+		   standards handy, it might even be valid for a
+		   bounds expression to contain a function reference,
+		   in which case I doubt it is permitted for an
+		   implementation to invoke that function in the
+		   Fortran case involved here (invocation of an
+		   alternate ENTRY point that doesn't have the adjustable
+		   array as one of its arguments).
+
+		   So, the code that the compiler would normally emit
+		   to preevaluate the size/shape info for an
+		   adjustable array _must not_ be executed at run time
+		   in certain cases.  Specifically, for Fortran,
+		   the case is when the pointer to the adjustable
+		   array == NULL.  (For gnu-ish C, it might be nice
+		   for the source code itself to specify an expression
+		   that, if TRUE, inhibits execution of the code.  Or
+		   reverse the sense for elegance.)
+
+		   (Note that g77 could use a different test than NULL,
+		   actually, since it happens to always pass an
+		   integer to the called function that specifies which
+		   entry point is being invoked.  Hmm, this might
+		   solve the next problem.)
+
+		   One way a user could, I suppose, write "foo" so
+		   it works is to insert COND_EXPR's for the
+		   size/shape info so the dangerous stuff isn't

+   the dummies and the inner holding the other vars), special care
+   must be taken to handle COMMON areas.
+
+   The current strategy is basically to always tell the back end about
+   the COMMON area as a top-level external reference to just a block
+   of storage of the master type of that area (e.g. integer, real,
+   character, whatever -- not a structure).  As a distinct action,
+   if initial values are provided, tell the back end about the area
+   as a top-level non-external (initialized) area and remember not to
+   allow further initialization or expansion of the area.  Meanwhile,
+   if no initialization happens at all, tell the back end about
+   the largest size we've seen declared so the space does get reserved.
+   (This function doesn't handle all that stuff, but it does some
+   of the important things.)
+
+   Meanwhile, for COMMON variables themselves, just keep creating
+   references like *((float *) (&common_area + offset)) each time
+   we reference the variable.  In other words, don't make a VAR_DECL
+   or any kind of component reference (like we used to do before 0.4),
+   though we might do that as well just for debugging purposes (and
+   stuff the rtl with the appropriate offset expression).  */

+   field filled in if its gone through here or exec_transition first, and
+   so on.
+
+   The backend probably wants to check ffesymbol_retractable() to see if
+   backtracking is in effect.  If so, the FFE's changes to the symbol may
+   be retracted (undone) or committed (ratified), at which time the
+   appropriate ffecom_sym_retract or _commit function will be called
+   for that function.
+
+   If the backend has its own backtracking mechanism, great, use it so that
+   committal is a simple operation.  Though it doesn't make much difference,
+   I suppose: the reason for tentative symbol evolution in the FFE is to
+   enable error detection in weird incorrect statements early and to disable
+   incorrect error detection on a correct statement.  The backend is not
+   likely to introduce any information that'll get involved in these
+   considerations, so it is probably just fine that the implementation
+   model for this fn and for _exec_transition is to not do anything
+   (besides the required FFE stuff) if ffesymbol_retractable() returns TRUE
+   and instead wait until ffecom_sym_commit is called (which it never
+   will be as long as we're using ambiguity-detecting statement analysis in
+   the FFE, which we are initially to shake out the code, but don't depend
+   on this), otherwise go ahead and do whatever is needed.
+
+   In essence, then, when this fn and _exec_transition get called while
+   backtracking is enabled, a general mechanism would be to flag which (or
+   both) of these were called (and in what order? neat question as to what
+   might happen that I'm too lame to think through right now) and then when
+   _commit is called reproduce the original calling sequence, if any, for
+   the two fns (at which point backtracking will, of course, be disabled).  */

+	 the compiler substitutes corresponding ..._TYPE nodes for TYPE_DECL
+	 (i.e. "typedef name") nodes very early on, later parts of the
+	 compiler can always do the reverse translation and get back the
+	 corresponding typedef name.  For example, given:
+
+	 typedef struct S MY_TYPE; MY_TYPE object;
+
+	 Later parts of the compiler might only know that `object' was of type
+	 `struct S' if it were not for code just below.  With this code
+	 however, later parts of the compiler see something like:
+
+	 struct S' == struct S typedef struct S' MY_TYPE; struct S' object;
+
+	 And they can then deduce (from the node for type struct S') that the
+	 original object declaration was:
+
+	 MY_TYPE object;
+
+	 Being able to do this is important for proper support of protoize, and
+	 also for generating precise symbolic debugging information which
+	 takes full account of the programmer's (typedef) vocabulary.
+
+	 Obviously, we don't want to generate a duplicate ..._TYPE node if the
+	 TYPE_DECL node that we are now processing really represents a
+	 standard built-in type.
+
+	 Since all standard types are effectively declared at line zero in the
+	 source file, we can easily check to see if we are working on a

+.IR option " | " "filename " ].\|.\|.
+.SH WARNING
+The information in this man page is an extract from the full
+documentation of the GNU Fortran compiler (version 0.5.24),
+and is limited to the meaning of some of the options.
+.PP
+This man page is not up to date, since no volunteers want to
+maintain it.  If you find a discrepancy between the man page and the
+software, please check the Info file, which is the authoritative
+documentation.
+.\" .PP
+.\" The version of GNU Fortran documented by the Info file is 0.5.24,
+.\" which includes substantial improvements and changes since 0.5.24,
+.\" the version documented in this man page.
+.PP
+If we find that the things in this man page that are out of date cause
+significant confusion or complaints, we will stop distributing the man
+page.  The alternative, updating the man page when we update the Info
+file, is impractical because the rest of the work of maintaining GNU Fortran
+leaves us no time for that.  The GNU project regards man pages as
+obsolete and should not let them take time away from other things.
+.PP
+For complete and current documentation, refer to the Info file `\|\c
+.B g77\c
+\&\|' or the manual
+.I
+Using and Porting GNU Fortran (for version 0.5.24)\c
+\&.  Both are made from the Texinfo source file
+.BR g77.texi .
+.PP
+If your system has the `\|\c
+.B info\c
+\&\|' command installed, the command `\|\c
+.B info g77\c
+\&\|' should work, unless
+.B g77
+has not been properly installed.
+If your system lacks `\|\c
+.B info\c
+\&\|', or you wish to avoid using it for now,
+the command `\|\c
+.B more /usr/info/g77.info*\c
+\&\|' should work, unless
+.B g77
+has not been properly installed.
+.PP
+If
+.B g77
+has not been properly installed, so that you
+cannot easily access the Info file for it,
+ask your system administrator, or the installer
+of
+.B g77
+(if you know who that is) to fix the problem.
+.SH DESCRIPTION
+The C and F77 compilers are integrated;
+.B g77
+is a program to call
+.B gcc
+with options to recognize programs written in Fortran (ANSI FORTRAN 77,
+also called F77).
+.B gcc
+processes input files
+through one or more of four stages: preprocessing, compilation,
+assembly, and linking.  This man page contains full descriptions for
+.I only
+F77-specific aspects of the compiler, though it also contains
+summaries of some general-purpose options.  For a fuller explanation
+of the compiler, see
+.BR gcc ( 1 ).
+
+For complete documentation on GNU Fortran, type `\|\c
+.B info g77\c
+\&\|'.
+
+F77 source files use the suffix `\|\c
+.B .f\c
+\&\|' or `\|\c
+.B .for\c
+\&\|'; F77 files to be preprocessed by
+.BR cpp ( 1 )
+use the suffix `\|\c
+.B .F\c
+\&\|' or `\|\c
+.B .fpp\c
+\&\|'; Ratfor source files use the suffix `\|\c
+.B .r\c
+\&\|' (though
+.B ratfor
+itself is not supplied as part of
+.B g77\c
+\&).
+.SH OPTIONS
+There are many command-line options, including options to control
+details of optimization, warnings, and code generation, which are
+common to both
+.B gcc
+and
+.B g77\c
+\&.  For full information on all options, see
+.BR gcc ( 1 ).
+
+Options must be separate: `\|\c
+.B \-dr\c
+\&\|' is quite different from `\|\c
+.B \-d \-r
+\&\|'.
+
+Most `\|\c
+.B \-f\c
+\&\|' and `\|\c
+.B \-W\c
+\&\|' options have two contrary forms:
+.BI \-f name
+and
+.BI \-fno\- name\c
+\& (or
+.BI \-W name
+and
+.BI \-Wno\- name\c
+\&). Only the non-default forms are shown here.
+
+.TP
+.B \-c
+Compile or assemble the source files, but do not link.  The compiler
+output is an object file corresponding to each source file.
+.TP
+.BI \-D macro
+Define macro \c
+.I macro\c
+\& with the string `\|\c
+.B 1\c
+\&\|' as its definition.
+.TP
+.BI \-D macro = defn
+Define macro \c
+.I macro\c
+\& as \c
+.I defn\c
+\&.
+.TP
+.B \-E
+Stop after the preprocessing stage; do not run the compiler proper.  The
+output is preprocessed source code, which is sent to the
+standard output.
+.TP
+.B \-g
+Produce debugging information in the operating system's native format
+(for DBX or SDB or DWARF).  GDB also can work with this debugging
+information.  On most systems that use DBX format, `\|\c
+.B \-g\c
+\&\|' enables use
+of extra debugging information that only GDB can use.
+
+Unlike most other Fortran compilers, GNU Fortran allows you to use `\|\c
+.B \-g\c
+\&\|' with
+`\|\c
+.B \-O\c
+\&\|'.  The shortcuts taken by optimized code may occasionally
+produce surprising results: some variables you declared may not exist
+at all; flow of control may briefly move where you did not expect it;
+some statements may not be executed because they compute constant
+results or their values were already at hand; some statements may
+execute in different places because they were moved out of loops.
+
+Nevertheless it proves possible to debug optimized output.  This makes
+it reasonable to use the optimizer for programs that might have bugs.
+.TP
+.BI "\-I" "dir"\c
+\&
+Append directory \c
+.I dir\c
+\& to the list of directories searched for include files.
+.TP
+.BI "\-L" "dir"\c
+\&
+Add directory \c
+.I dir\c
+\& to the list of directories to be searched
+for `\|\c
+.B \-l\c
+\&\|'.
+.TP
+.BI \-l library\c
+\&
+Use the library named \c
+.I library\c
+\& when linking.
+.TP
+.B \-nostdinc
+Do not search the standard system directories for header files.  Only
+the directories you have specified with
+.B \-I
+options (and the current directory, if appropriate) are searched.
+.TP
+.B \-O
+Optimize.  Optimizing compilation takes somewhat more time, and a lot
+more memory for a large function.  See the GCC documentation for
+further optimisation options.  Loop unrolling, in particular, may be
+worth investigating for typical numerical Fortran programs.
+.TP
+.BI "\-o " file\c
+\&
+Place output in file \c
+.I file\c
+\&.
+.TP
+.B \-S
+Stop after the stage of compilation proper; do not assemble.  The output
+is an assembler code file for each non-assembler input
+file specified.
+.TP
+.BI \-U macro
+Undefine macro \c
+.I macro\c
+\&.
+.TP
+.B \-v

+@unnumbered GNU GENERAL PUBLIC LICENSE
+@center Version 2, June 1991
+
+@display
+Copyright @copyright{} 1989, 1991 Free Software Foundation, Inc.
+59 Temple Place - Suite 330, Boston, MA 02111-1307, USA
+
+Everyone is permitted to copy and distribute verbatim copies
+of this license document, but changing it is not allowed.
+@end display
+
+@unnumberedsec Preamble
+
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software---to make sure the software is free for all its users.  This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it.  (Some other Free Software Foundation software is covered by
+the GNU Library General Public License instead.)  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+  To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have.  You must make sure that they, too, receive or can get the
+source code.  And you must show them these terms so they know their
+rights.
+
+  We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+  Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software.  If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+  Finally, any free program is threatened constantly by software
+patents.  We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary.  To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+@iftex
+@unnumberedsec TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+@end iftex
+@ifinfo
+@center TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+@end ifinfo
+
+@enumerate 0
+@item
+This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License.  The ``Program'', below,
+refers to any such program or work, and a ``work based on the Program''
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language.  (Hereinafter, translation is included without limitation in
+the term ``modification''.)  Each licensee is addressed as ``you''.
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+@item
+You may copy and distribute verbatim copies of the Program's
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+@item
+You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+@enumerate a
+@item
+You must cause the modified files to carry prominent notices
+stating that you changed the files and the date of any change.
+
+@item
+You must cause any work that you distribute or publish, that in
+whole or in part contains or is derived from the Program or any
+part thereof, to be licensed as a whole at no charge to all third
+parties under the terms of this License.
+
+@item
+If the modified program normally reads commands interactively
+when run, you must cause it, when started running for such
+interactive use in the most ordinary way, to print or display an
+announcement including an appropriate copyright notice and a
+notice that there is no warranty (or else, saying that you provide
+a warranty) and that users may redistribute the program under
+these conditions, and telling the user how to view a copy of this
+License.  (Exception: if the Program itself is interactive but
+does not normally print such an announcement, your work based on
+the Program is not required to print an announcement.)
+@end enumerate
+
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+@item
+You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+@enumerate a
+@item
+Accompany it with the complete corresponding machine-readable
+source code, which must be distributed under the terms of Sections
+1 and 2 above on a medium customarily used for software interchange; or,
+
+@item
+Accompany it with a written offer, valid for at least three
+years, to give any third party, for a charge no more than your
+cost of physically performing source distribution, a complete
+machine-readable copy of the corresponding source code, to be
+distributed under the terms of Sections 1 and 2 above on a medium
+customarily used for software interchange; or,
+
+@item
+Accompany it with the information you received as to the offer
+to distribute corresponding source code.  (This alternative is
+allowed only for noncommercial distribution and only if you
+received the program in object code or executable form with such
+an offer, in accord with Subsection b above.)
+@end enumerate
+
+The source code for a work means the preferred form of the work for
+making modifications to it.  For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable.  However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+@item
+You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License.  Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+@item
+You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Program or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+@item
+Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+@item
+If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+@item
+If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded.  In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+@item
+The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the Program
+specifies a version number of this License which applies to it and ``any
+later version'', you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation.  If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+@item
+If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission.  For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this.  Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+@iftex
+@heading NO WARRANTY
+@end iftex
+@ifinfo

+BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM ``AS IS'' WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED

+IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING

+@node Funding
+@chapter Funding Free Software
+
+If you want to have more free software a few years from now, it makes
+sense for you to help encourage people to contribute funds for its
+development.  The most effective approach known is to encourage
+commercial redistributors to donate.
+
+Users of free software systems can boost the pace of development by
+encouraging for-a-fee distributors to donate part of their selling price
+to free software developers---the Free Software Foundation, and others.
+
+The way to convince distributors to do this is to demand it and expect
+it from them.  So when you compare distributors, judge them partly by
+how much they give to free software development.  Show distributors
+they must compete to be the one who gives the most.
+
+To make this approach work, you must insist on numbers that you can
+compare, such as, ``We will donate ten dollars to the Frobnitz project
+for each disk sold.''  Don't be satisfied with a vague promise, such as
+``A portion of the profits are donated,'' since it doesn't give a basis
+for comparison.
+
+Even a precise fraction ``of the profits from this disk'' is not very
+meaningful, since creative accounting and unrelated business decisions
+can greatly alter what fraction of the sales price counts as profit.
+If the price you pay is $50, ten percent of the profit is probably
+less than a dollar; it might be a few cents, or nothing at all.
+
+Some redistributors do development work themselves.  This is useful too;
+but to keep everyone honest, you need to inquire how much they do, and
+what kind.  Some kinds of development make much more long-term
+difference than others.  For example, maintaining a separate version of
+a program contributes very little; maintaining the standard version of a
+program for the whole community contributes much.  Easy new ports
+contribute little, since someone else would surely do them; difficult
+ports such as adding a new CPU to the GNU C compiler contribute more;
+major new features or packages contribute the most.
+
+By establishing the idea that supporting further development is ``the
+proper thing to do'' when distributing free software for a fee, we can
+assure a steady flow of resources into making more free software.

+@cindex funding improvements
+@cindex improvements, funding
+
+Work on GNU Fortran is still being done mostly by its author,
+James Craig Burley (@email{@value{email-burley}}), who is a volunteer
+for, not an employee of, the Free Software Foundation (FSF).
+As with other GNU software, funding is important because it can pay for
+needed equipment, personnel, and so on.
+
+@cindex FSF, funding the
+@cindex funding the FSF
+The FSF provides information on the best way to fund ongoing
+development of GNU software (such as GNU Fortran) in documents
+such as the ``GNUS Bulletin''.
+Email @email{gnu@@gnu.org} for information on funding the FSF.
+
+To fund specific GNU Fortran work in particular, the FSF might
+provide a means for that, but the FSF does not provide direct funding
+to the author of GNU Fortran to continue his work.  The FSF has
+employee salary restrictions that can be incompatible with the
+financial needs of some volunteers, who therefore choose to
+remain volunteers and thus be able to be free to do contract work
+and otherwise make their own schedules for doing GNU work.
+
+Still, funding the FSF at least indirectly benefits work
+on specific projects like GNU Fortran because it ensures the
+continuing operation of the FSF offices, their workstations, their
+network connections, and so on, which are invaluable to volunteers.
+(Similarly, hiring Cygnus Support can help a project like GNU
+Fortran---Cygnus has been a long-time donor of equipment usage to the author
+of GNU Fortran, and this too has been invaluable---@xref{Contributors}.)
+
+Currently, the only way to directly fund the author of GNU Fortran
+in his work on that project is to hire him for the work you want
+him to do, or donate money to him.
+Several people have done this
+already, with the result that he has not needed to immediately find
+contract work on a few occasions.
+If more people did this, he
+would be able to plan on not doing contract work for many months and
+could thus devote that time to work on projects (such as the planned
+changes for 0.6) that require longer timeframes to complete.
+For the latest information on the status of the author, do
+@kbd{finger -l burley@@gnu.org} on a UNIX system
+(or any system with a command like UNIX @code{finger}).
+
+Another important way to support work on GNU Fortran is to volunteer
+to help out.
+Work is needed on documentation, testing, porting
+to various machines, and in some cases, coding (although major
+changes planned for version 0.6 make it difficult to add manpower to this
+area).

+@chapter What is GNU Fortran?
+@cindex concepts, basic
+@cindex basic concepts
+
+GNU Fortran, or @code{g77}, is designed initially as a free replacement
+for, or alternative to, the UNIX @code{f77} command.
+(Similarly, @code{gcc} is designed as a replacement
+for the UNIX @code{cc} command.)
+
+@code{g77} also is designed to fit in well with the other
+fine GNU compilers and tools.
+
+Sometimes these design goals conflict---in such cases, resolution
+often is made in favor of fitting in well with Project GNU.
+These cases are usually identified in the appropriate
+sections of this manual.
+
+@cindex compilers
+As compilers, @code{g77}, @code{gcc}, and @code{f77}
+share the following characteristics:
+
+@itemize @bullet
+@cindex source code
+@cindex file, source
+@cindex code, source
+@cindex source file
+@item
+They read a user's program, stored in a file and
+containing instructions written in the appropriate
+language (Fortran, C, and so on).
+This file contains @dfn{source code}.
+
+@cindex translation of user programs
+@cindex machine code
+@cindex code, machine
+@cindex mistakes
+@item
+They translate the user's program into instructions
+a computer can carry out more quickly than it takes
+to translate the instructions in the first place.
+These instructions are called @dfn{machine code}---code
+designed to be efficiently translated and processed
+by a machine such as a computer.
+Humans usually aren't as good writing machine code
+as they are at writing Fortran or C, because
+it is easy to make tiny mistakes writing machine code.
+When writing Fortran or C, it is easy
+to make big mistakes.
+
+@cindex debugger
+@cindex bugs, finding
+@cindex gdb command
+@cindex commands, gdb
+@item
+They provide information in the generated machine code
+that can make it easier to find bugs in the program
+(using a debugging tool, called a @dfn{debugger},
+such as @code{gdb}).
+
+@cindex libraries
+@cindex linking
+@cindex ld command
+@cindex commands, ld
+@item
+They locate and gather machine code already generated
+to perform actions requested by statements in
+the user's program.
+This machine code is organized
+into @dfn{libraries} and is located and gathered
+during the @dfn{link} phase of the compilation
+process.
+(Linking often is thought of as a separate
+step, because it can be directly invoked via the
+@code{ld} command.
+However, the @code{g77} and @code{gcc}
+commands, as with most compiler commands, automatically
+perform the linking step by calling on @code{ld}
+directly, unless asked to not do so by the user.)
+
+@cindex language, incorrect use of
+@cindex incorrect use of language
+@item
+They attempt to diagnose cases where the user's
+program contains incorrect usages of the language.
+The @dfn{diagnostics} produced by the compiler
+indicate the problem and the location in the user's
+source file where the problem was first noticed.
+The user can use this information to locate and
+fix the problem.
+@cindex diagnostics, incorrect
+@cindex incorrect diagnostics
+@cindex error messages, incorrect
+@cindex incorrect error messages
+(Sometimes an incorrect usage
+of the language leads to a situation where the
+compiler can no longer make any sense of what
+follows---while a human might be able to---and
+thus ends up complaining about many ``problems''
+it encounters that, in fact, stem from just one
+problem, usually the first one reported.)
+
+@cindex warnings
+@cindex questionable instructions
+@item
+They attempt to diagnose cases where the user's
+program contains a correct usage of the language,
+but instructs the computer to do something questionable.
+These diagnostics often are in the form of @dfn{warnings},
+instead of the @dfn{errors} that indicate incorrect
+usage of the language.
+@end itemize
+
+How these actions are performed is generally under the
+control of the user.
+Using command-line options, the user can specify
+how persnickety the compiler is to be regarding
+the program (whether to diagnose questionable usage
+of the language), how much time to spend making
+the generated machine code run faster, and so on.
+
+@cindex components of g77
+@cindex g77, components of
+@code{g77} consists of several components:
+
+@cindex gcc command
+@cindex commands, gcc
+@itemize @bullet
+@item
+A modified version of the @code{gcc} command, which also might be
+installed as the system's @code{cc} command.
+(In many cases, @code{cc} refers to the
+system's ``native'' C compiler, which
+might be a non-GNU compiler, or an older version
+of @code{gcc} considered more stable or that is
+used to build the operating system kernel.)
+
+@cindex g77 command
+@cindex commands, g77
+@item
+The @code{g77} command itself, which also might be installed as the
+system's @code{f77} command.
+
+@cindex libg2c library
+@cindex libf2c library
+@cindex libraries, libf2c
+@cindex libraries, libg2c
+@cindex run-time library
+@item
+The @code{libg2c} run-time library.
+This library contains the machine code needed to support
+capabilities of the Fortran language that are not directly
+provided by the machine code generated by the @code{g77}
+compilation phase.
+
+@code{libg2c} is just the unique name @code{g77} gives
+to its version of @code{libf2c} to distinguish it from
+any copy of @code{libf2c} installed from @code{f2c}
+(or versions of @code{g77} that built @code{libf2c} under
+that same name)
+on the system.
+
+The maintainer of @code{libf2c} currently is
+@email{dmg@@bell-labs.com}.
+
+@cindex f771 program
+@cindex programs, f771
+@cindex assembler
+@cindex as command
+@cindex commands, as
+@cindex assembly code
+@cindex code, assembly
+@item
+The compiler itself, internally named @code{f771}.
+
+Note that @code{f771} does not generate machine code directly---it
+generates @dfn{assembly code} that is a more readable form
+of machine code, leaving the conversion to actual machine code
+to an @dfn{assembler}, usually named @code{as}.
+@end itemize
+
+@code{gcc} is often thought of as ``the C compiler'' only,
+but it does more than that.
+Based on command-line options and the names given for files
+on the command line, @code{gcc} determines which actions to perform, including
+preprocessing, compiling (in a variety of possible languages), assembling,
+and linking.
+

+@cindex executable file

+@cindex cc1 program
+@cindex programs, cc1
+@cindex preprocessor
+@cindex cpp program
+@cindex programs, cpp
+For example, the command @samp{gcc foo.c} @dfn{drives} the file
+@file{foo.c} through the preprocessor @code{cpp}, then
+the C compiler (internally named
+@code{cc1}), then the assembler (usually @code{as}), then the linker
+(@code{ld}), producing an executable program named @file{a.out} (on
+UNIX systems).
+
+@cindex cc1plus program
+@cindex programs, cc1plus
+As another example, the command @samp{gcc foo.cc} would do much the same as
+@samp{gcc foo.c}, but instead of using the C compiler named @code{cc1},
+@code{gcc} would use the C++ compiler (named @code{cc1plus}).
+
+@cindex f771 program
+@cindex programs, f771
+In a GNU Fortran installation, @code{gcc} recognizes Fortran source
+files by name just like it does C and C++ source files.
+It knows to use the Fortran compiler named @code{f771}, instead of
+@code{cc1} or @code{cc1plus}, to compile Fortran files.
+
+@cindex gcc not recognizing Fortran source
+@cindex unrecognized file format
+@cindex file format not recognized
+Non-Fortran-related operation of @code{gcc} is generally
+unaffected by installing the GNU Fortran version of @code{gcc}.
+However, without the installed version of @code{gcc} being the
+GNU Fortran version, @code{gcc} will not be able to compile
+and link Fortran programs---and since @code{g77} uses @code{gcc}
+to do most of the actual work, neither will @code{g77}!
+
+@cindex g77 command
+@cindex commands, g77
+The @code{g77} command is essentially just a front-end for
+the @code{gcc} command.
+Fortran users will normally use @code{g77} instead of @code{gcc},
+because @code{g77}
+knows how to specify the libraries needed to link with Fortran programs
+(@code{libg2c} and @code{lm}).
+@code{g77} can still compile and link programs and
+source files written in other languages, just like @code{gcc}.
+
+@cindex printing version information
+@cindex version information, printing
+The command @samp{g77 -v} is a quick
+way to display lots of version information for the various programs
+used to compile a typical preprocessed Fortran source file---this
+produces much more output than @samp{gcc -v} currently does.
+(If it produces an error message near the end of the output---diagnostics
+from the linker, usually @code{ld}---you might
+have an out-of-date @code{libf2c} that improperly handles
+complex arithmetic.)
+In the output of this command, the line beginning @samp{GNU Fortran Front
+End} identifies the version number of GNU Fortran; immediately
+preceding that line is a line identifying the version of @code{gcc}
+with which that version of @code{g77} was built.
+
+@cindex libf2c library
+@cindex libraries, libf2c
+The @code{libf2c} library is distributed with GNU Fortran for
+the convenience of its users, but is not part of GNU Fortran.
+It contains the procedures
+needed by Fortran programs while they are running.
+
+@cindex in-line code
+@cindex code, in-line
+For example, while code generated by @code{g77} is likely
+to do additions, subtractions, and multiplications @dfn{in line}---in
+the actual compiled code---it is not likely to do trigonometric
+functions this way.
+
+Instead, operations like trigonometric
+functions are compiled by the @code{f771} compiler
+(invoked by @code{g77} when compiling Fortran code) into machine
+code that, when run, calls on functions in @code{libg2c}, so
+@code{libg2c} must be linked with almost every useful program
+having any component compiled by GNU Fortran.
+(As mentioned above, the @code{g77} command takes
+care of all this for you.)
+
+The @code{f771} program represents most of what is unique to GNU Fortran.
+While much of the @code{libg2c} component comes from
+the @code{libf2c} component of @code{f2c},
+a free Fortran-to-C converter distributed by Bellcore (AT&T),
+plus @code{libU77}, provided by Dave Love,
+and the @code{g77} command is just a small front-end to @code{gcc},
+@code{f771} is a combination of two rather
+large chunks of code.
+
+@cindex GNU Back End (GBE)
+@cindex GBE
+@cindex gcc back end
+@cindex back end, gcc
+@cindex code generator
+One chunk is the so-called @dfn{GNU Back End}, or GBE,
+which knows how to generate fast code for a wide variety of processors.
+The same GBE is used by the C, C++, and Fortran compiler programs @code{cc1},
+@code{cc1plus}, and @code{f771}, plus others.
+Often the GBE is referred to as the ``gcc back end'' or
+even just ``gcc''---in this manual, the term GBE is used
+whenever the distinction is important.
+
+@cindex GNU Fortran Front End (FFE)
+@cindex FFE
+@cindex g77 front end
+@cindex front end, g77
+The other chunk of @code{f771} is the
+majority of what is unique about GNU Fortran---the code that knows how
+to interpret Fortran programs to determine what they are intending to
+do, and then communicate that knowledge to the GBE for actual compilation
+of those programs.
+This chunk is called the @dfn{Fortran Front End} (FFE).
+The @code{cc1} and @code{cc1plus} programs have their own front ends,
+for the C and C++ languages, respectively.
+These fronts ends are responsible for diagnosing
+incorrect usage of their respective languages by the
+programs the process, and are responsible for most of
+the warnings about questionable constructs as well.
+(The GBE handles producing some warnings, like those
+concerning possible references to undefined variables.)
+
+Because so much is shared among the compilers for various languages,
+much of the behavior and many of the user-selectable options for these
+compilers are similar.
+For example, diagnostics (error messages and
+warnings) are similar in appearance; command-line
+options like @samp{-Wall} have generally similar effects; and the quality
+of generated code (in terms of speed and size) is roughly similar
+(since that work is done by the shared GBE).

+Compilation can involve as many as four stages: preprocessing, code
+generation (often what is really meant by the term ``compilation''),
+assembly, and linking, always in that order.  The first three
+stages apply to an individual source file, and end by producing an
+object file; linking combines all the object files (those newly
+compiled, and those specified as input) into an executable file.

+For any given input file, the file name suffix determines what kind of

+program is written is generally indicated by the suffix.
+Suffixes specific to GNU Fortran are listed below.

+Fortran source code that must be preprocessed (by the C preprocessor
+@code{cpp}, which is part of GNU CC).
+
+Note that preprocessing is not extended to the contents of
+files included by the @code{INCLUDE} directive---the @code{#include}
+preprocessor directive must be used instead.
+
+@cindex Ratfor preprocessor
+@cindex programs, ratfor
+@cindex .r filename suffix
+@pindex ratfor
+@item @var{file}.r
+Ratfor source code, which must be preprocessed by the @code{ratfor}
+command, which is available separately (as it is not yet part of the GNU
+Fortran distribution).
+One version in Fortran, adapted for use with @code{g77}, is at
+@uref{ftp://members.aol.com/n8tm/rat7.uue} (of uncertain copyright
+status).  Another, public domain version in C is at
+@uref{http://sepwww.stanford.edu/sep/prof/ratfor.shar.2}.
+@end table
+
+UNIX users typically use the @file{@var{file}.f} and @file{@var{file}.F}
+nomenclature.
+Users of other operating systems, especially those that cannot
+distinguish upper-case
+letters from lower-case letters in their file names, typically use
+the @file{@var{file}.for} and @file{@var{file}.fpp} nomenclature.
+
+@cindex #define
+@cindex #include
+@cindex #if
+Use of the preprocessor @code{cpp} allows use of C-like
+constructs such as @code{#define} and @code{#include}, but can
+lead to unexpected, even mistaken, results due to Fortran's source file
+format.
+It is recommended that use of the C preprocessor
+be limited to @code{#include} and, in
+conjunction with @code{#define}, only @code{#if} and related directives,
+thus avoiding in-line macro expansion entirely.
+This recommendation applies especially
+when using the traditional fixed source form.
+With free source form,
+fewer unexpected transformations are likely to happen, but use of
+constructs such as Hollerith and character constants can nevertheless
+present problems, especially when these are continued across multiple
+source lines.
+These problems result, primarily, from differences between the way
+such constants are interpreted by the C preprocessor and by a Fortran
+compiler.
+
+Another example of a problem that results from using the C preprocessor
+is that a Fortran comment line that happens to contain any
+characters ``interesting'' to the C preprocessor,
+such as a backslash at the end of the line,
+is not recognized by the preprocessor as a comment line,
+so instead of being passed through ``raw'',
+the line is edited according to the rules for the preprocessor.
+For example, the backslash at the end of the line is removed,
+along with the subsequent newline, resulting in the next
+line being effectively commented out---unfortunate if that
+line is a non-comment line of important code!
+
+@emph{Note:} The @samp{-traditional} and @samp{-undef} flags are supplied
+to @code{cpp} by default, to help avoid unpleasant surprises.
+@xref{Preprocessor Options,,Options Controlling the Preprocessor,
+gcc,Using and Porting GNU CC}.
+This means that ANSI C preprocessor features (such as the @samp{#}
+operator) aren't available, and only variables in the C reserved
+namespace (generally, names with a leading underscore) are liable to
+substitution by C predefines.
+Thus, if you want to do system-specific
+tests, use, for example, @samp{#ifdef __linux__} rather than @samp{#ifdef linux}.
+Use the @samp{-v} option to see exactly how the preprocessor is invoked.
+
+@cindex /*
+Unfortunately, the @samp{-traditional} flag will not avoid an error from
+anything that @code{cpp} sees as an unterminated C comment, such as:
+@smallexample
+C Some Fortran compilers accept /* as starting
+C an inline comment.

+And @samp{F = FUNC()} is treated as @samp{F = FUNC(%VAL(0))}.
+
+The default behavior, @samp{-fno-ugly-comma}, is to ignore
+a single trailing comma in an argument list.

+@cindex one-trip DO loops
+@cindex compatibility, FORTRAN 66
+Imperative executable @code{DO} loops are to be executed at
+least once each time they are reached.
+
+ANSI FORTRAN 77 and more recent versions of the Fortran standard
+specify that the body of an imperative @code{DO} loop is not executed
+if the number of iterations calculated from the parameters of the
+loop is less than 1.
+(For example, @samp{DO 10 I = 1, 0}.)
+Such a loop is called a @dfn{zero-trip loop}.
+
+Prior to ANSI FORTRAN 77, many compilers implemented @code{DO} loops
+such that the body of a loop would be executed at least once, even
+if the iteration count was zero.
+Fortran code written assuming this behavior is said to require
+@dfn{one-trip loops}.
+For example, some code written to the FORTRAN 66 standard
+expects this behavior from its @code{DO} loops, although that
+standard did not specify this behavior.
+
+The @samp{-fonetrip} option specifies that the source file(s) being
+compiled require one-trip loops.
+
+This option affects only those loops specified by the (imperative) @code{DO}
+statement and by implied-@code{DO} lists in I/O statements.
+Loops specified by implied-@code{DO} lists in @code{DATA} and
+specification (non-executable) statements are not affected.

+END

+based on a command-line option specifying some kind of
+compatibility.

+@cindex warning messages
+@cindex messages, warning
+@cindex suppressing warnings
+
+Warnings are diagnostic messages that report constructions which
+are not inherently erroneous but which are risky or suggest there
+might have been an error.
+
+You can request many specific warnings with options beginning @samp{-W},
+for example @samp{-Wimplicit} to request warnings on implicit
+declarations.  Each of these specific warning options also has a
+negative form beginning @samp{-Wno-} to turn off warnings;
+for example, @samp{-Wno-implicit}.  This manual lists only one of the
+two forms, whichever is not the default.
+
+These options control the amount and kinds of warnings produced by GNU
+Fortran:
+
+@table @code
+@cindex syntax checking
+@cindex -fsyntax-only option
+@cindex options, -fsyntax-only
+@item -fsyntax-only
+Check the code for syntax errors, but don't do anything beyond that.
+
+@cindex -pedantic option
+@cindex options, -pedantic
+@item -pedantic
+Issue warnings for uses of extensions to ANSI FORTRAN 77.
+@samp{-pedantic} also applies to C-language constructs where they
+occur in GNU Fortran source files, such as use of @samp{\e} in a
+character constant within a directive like @samp{#include}.
+
+Valid ANSI FORTRAN 77 programs should compile properly with or without
+this option.
+However, without this option, certain GNU extensions and traditional
+Fortran features are supported as well.
+With this option, many of them are rejected.
+
+Some users try to use @samp{-pedantic} to check programs for strict ANSI
+conformance.
+They soon find that it does not do quite what they want---it finds some
+non-ANSI practices, but not all.
+However, improvements to @code{g77} in this area are welcome.
+
+@cindex -pedantic-errors option
+@cindex options, -pedantic-errors
+@item -pedantic-errors
+Like @samp{-pedantic}, except that errors are produced rather than
+warnings.
+
+@cindex -fpedantic option
+@cindex options, -fpedantic
+@item -fpedantic
+Like @samp{-pedantic}, but applies only to Fortran constructs.
+
+@cindex -w option
+@cindex options, -w
+@item -w
+Inhibit all warning messages.
+
+@cindex -Wno-globals option
+@cindex options, -Wno-globals
+@item -Wno-globals
+@cindex global names, warning
+@cindex warnings, global names
+Inhibit warnings about use of a name as both a global name
+(a subroutine, function, or block data program unit, or a
+common block) and implicitly as the name of an intrinsic
+in a source file.
+
+Also inhibit warnings about inconsistent invocations and/or
+definitions of global procedures (function and subroutines).
+Such inconsistencies include different numbers of arguments
+and different types of arguments.
+
+@cindex -Wimplicit option
+@cindex options, -Wimplicit
+@item -Wimplicit
+@cindex implicit declaration, warning
+@cindex warnings, implicit declaration
+@cindex -u option
+@cindex /WARNINGS=DECLARATIONS switch
+@cindex IMPLICIT NONE, similar effect
+@cindex effecting IMPLICIT NONE
+Warn whenever a variable, array, or function is implicitly
+declared.
+Has an effect similar to using the @code{IMPLICIT NONE} statement
+in every program unit.
+(Some Fortran compilers provide this feature by an option
+named @samp{-u} or @samp{/WARNINGS=DECLARATIONS}.)
+
+@cindex -Wunused option
+@cindex options, -Wunused
+@item -Wunused
+@cindex unused variables
+@cindex variables, unused
+Warn whenever a variable is unused aside from its declaration.
+
+@cindex -Wuninitialized option
+@cindex options, -Wuninitialized
+@item -Wuninitialized
+@cindex uninitialized variables
+@cindex variables, uninitialized
+Warn whenever an automatic variable is used without first being initialized.
+
+These warnings are possible only in optimizing compilation,
+because they require data-flow information that is computed only
+when optimizing.  If you don't specify @samp{-O}, you simply won't
+get these warnings.
+
+These warnings occur only for variables that are candidates for
+register allocation.  Therefore, they do not occur for a variable
+@c that is declared @code{VOLATILE}, or
+whose address is taken, or whose size
+is other than 1, 2, 4 or 8 bytes.  Also, they do not occur for
+arrays, even when they are in registers.
+
+Note that there might be no warning about a variable that is used only
+to compute a value that itself is never used, because such
+computations may be deleted by data-flow analysis before the warnings
+are printed.
+
+These warnings are made optional because GNU Fortran is not smart
+enough to see all the reasons why the code might be correct
+despite appearing to have an error.  Here is one example of how
+this can happen:
+
+@example
+SUBROUTINE DISPAT(J)
+IF (J.EQ.1) I=1
+IF (J.EQ.2) I=4
+IF (J.EQ.3) I=5
+CALL FOO(I)
+END
+@end example
+
+@noindent
+If the value of @code{J} is always 1, 2 or 3, then @code{I} is
+always initialized, but GNU Fortran doesn't know this.  Here is
+another common case:
+
+@example
+SUBROUTINE MAYBE(FLAG)
+LOGICAL FLAG
+IF (FLAG) VALUE = 9.4
+@dots{}
+IF (FLAG) PRINT *, VALUE
+END
+@end example
+
+@noindent
+This has no bug because @code{VALUE} is used only if it is set.
+
+@cindex -Wall option
+@cindex options, -Wall
+@item -Wall
+@cindex all warnings
+@cindex warnings, all
+The @samp{-Wunused} and @samp{-Wuninitialized} options combined.
+These are all the

+(As more warnings are added to @code{g77}, some might
+be added to the list enabled by @samp{-Wall}.)
+@end table
+
+The remaining @samp{-W@dots{}} options are not implied by @samp{-Wall}
+because they warn about constructions that we consider reasonable to
+use, on occasion, in clean programs.

+@cindex -Wsurprising option
+@cindex options, -Wsurprising
+@item -Wsurprising
+Warn about ``suspicious'' constructs that are interpreted
+by the compiler in a way that might well be surprising to
+someone reading the code.
+These differences can result in subtle, compiler-dependent
+(even machine-dependent) behavioral differences.
+The constructs warned about include:
+
+@itemize @bullet
+@item
+Expressions having two arithmetic operators in a row, such
+as @samp{X*-Y}.
+Such a construct is nonstandard, and can produce
+unexpected results in more complicated situations such
+as @samp{X**-Y*Z}.
+@code{g77}, along with many other compilers, interprets
+this example differently than many programmers, and a few
+other compilers.
+Specifically, @code{g77} interprets @samp{X**-Y*Z} as
+@samp{(X**(-Y))*Z}, while others might think it should
+be interpreted as @samp{X**(-(Y*Z))}.
+
+A revealing example is the constant expression @samp{2**-2*1.},
+which @code{g77} evaluates to .25, while others might evaluate
+it to 0., the difference resulting from the way precedence affects
+type promotion.
+
+(The @samp{-fpedantic} option also warns about expressions
+having two arithmetic operators in a row.)
+
+@item
+Expressions with a unary minus followed by an operand and then
+a binary operator other than plus or minus.
+For example, @samp{-2**2} produces a warning, because
+the precedence is @samp{-(2**2)}, yielding -4, not
+@samp{(-2)**2}, which yields 4, and which might represent
+what a programmer expects.
+
+An example of an expression producing different results
+in a surprising way is @samp{-I*S}, where @var{I} holds
+the value @samp{-2147483648} and @var{S} holds @samp{0.5}.
+On many systems, negating @var{I} results in the same
+value, not a positive number, because it is already the
+lower bound of what an @code{INTEGER(KIND=1)} variable can hold.
+So, the expression evaluates to a positive number, while
+the ``expected'' interpretation, @samp{(-I)*S}, would
+evaluate to a negative number.
+
+Even cases such as @samp{-I*J} produce warnings,
+even though, in most configurations and situations,
+there is no computational difference between the
+results of the two interpretations---the purpose
+of this warning is to warn about differing interpretations
+and encourage a better style of coding, not to identify
+only those places where bugs might exist in the user's
+code.
+
+@cindex DO statement
+@cindex statements, DO
+@item
+@code{DO} loops with @code{DO} variables that are not
+of integral type---that is, using @code{REAL}
+variables as loop control variables.
+Although such loops can be written to work in the
+``obvious'' way, the way @code{g77} is required by the
+Fortran standard to interpret such code is likely to
+be quite different from the way many programmers expect.

+@cindex options, debugging
+@cindex debugging information options
+
+GNU Fortran has various special options that are used for debugging
+either your program or @code{g77}.
+
+@table @code
+@cindex -g option
+@cindex options, -g
+@item -g
+Produce debugging information in the operating system's native format
+(stabs, COFF, XCOFF, or DWARF).  GDB can work with this debugging
+information.
+
+@cindex common blocks
+@cindex equivalence areas
+@cindex missing debug features
+Support for this option in Fortran programs is incomplete.
+In particular, names of variables and arrays in common blocks
+or that are storage-associated via @code{EQUIVALENCE} are
+unavailable to the debugger.
+
+However, version 0.5.19 of @code{g77} does provide this information
+in a rudimentary way, as controlled by the
+@samp{-fdebug-kludge} option.

+
+@node Optimize Options
+@section Options That Control Optimization
+@cindex optimize options
+@cindex options, optimization
+
+Most Fortran users will want to use no optimization when
+developing and testing programs, and use @samp{-O} or @samp{-O2} when
+compiling programs for late-cycle testing and for production use.
+However, note that certain diagnostics---such as for uninitialized
+variables---depend on the flow analysis done by @samp{-O}, i.e.@: you
+must use @samp{-O} or @samp{-O2} to get such diagnostics.
+
+The following flags have particular applicability when
+compiling Fortran programs:
+
+@table @code
+@cindex -malign-double option
+@cindex options, -malign-double
+@item -malign-double
+(Intel x86 architecture only.)
+
+Noticeably improves performance of @code{g77} programs making
+heavy use of @code{REAL(KIND=2)} (@code{DOUBLE PRECISION}) data
+on some systems.
+In particular, systems using Pentium, Pentium Pro, 586, and
+686 implementations
+of the i386 architecture execute programs faster when
+@code{REAL(KIND=2)} (@code{DOUBLE PRECISION}) data are
+aligned on 64-bit boundaries
+in memory.
+
+This option can, at least, make benchmark results more consistent
+across various system configurations, versions of the program,
+and data sets.
+
+@emph{Note:} The warning in the @code{gcc} documentation about
+this option does not apply, generally speaking, to Fortran
+code compiled by @code{g77}.
+
+@emph{Also note:} @samp{-malign-double} applies only to
+statically-allocated data.
+Double-precision data on the stack can still
+cause problems due to misalignment.
+@xref{Aligned Data}.
+
+@emph{Also also note:} The negative form of @samp{-malign-double}
+is @samp{-mno-align-double}, not @samp{-benign-double}.
+
+@cindex -ffloat-store option
+@cindex options, -ffloat-store
+@item -ffloat-store
+@cindex IEEE conformance
+@cindex conformance, IEEE
+@cindex floating point precision
+Might help a Fortran program that depends on exact IEEE conformance on
+some machines, but might slow down a program that doesn't.
+
+This option is effective when the floating point unit is set to work in
+IEEE 854 `extended precision'---as it typically is on x86 and m68k GNU
+systems---rather than IEEE 754 double precision.  @code{-ffloat-store}
+tries to remove the extra precision by spilling data from floating point
+registers into memory and this typically involves a big performance
+hit.  However, it doesn't affect intermediate results, so that it is
+only partially effective.  `Excess precision' is avoided in code like:
+@smallexample
+a = b + c
+d = a * e
+@end smallexample
+but not in code like:
+@smallexample
+      d = (b + c) * e
+@end smallexample

+@ref{Floating point precision}.

+@c DL: Only relevant for -O3?
+Don't compile statement functions inline.
+Might reduce the size of a program unit---which might be at

+
+@cindex -funroll-loops option
+@cindex options, -funroll-loops
+@item -funroll-loops
+@cindex loops, unrolling
+@cindex unrolling loops
+@cindex loop optimization
+@c DL: fixme: Craig doesn't like `indexed' but f95 doesn't seem to
+@c provide a suitable term
+Typically improves performance on code using indexed @code{DO} loops by
+unrolling them and is probably generally appropriate for Fortran, though
+it is not turned on at any optimization level.  
+Note that outer loop unrolling isn't done specifically; decisions about
+whether to unroll a loop are made on the basis of its instruction count.  
+
+@c DL: Fixme: This should obviously go somewhere else...
+Also, no `loop discovery'@footnote{@dfn{loop discovery} refers to the
+process by which a compiler, or indeed any reader of a program,
+determines which portions of the program are more likely to be executed
+repeatedly as it is being run.  Such discovery typically is done early
+when compiling using optimization techniques, so the ``discovered''
+loops get more attention---and more run-time resources, such as
+registers---from the compiler.  It is easy to ``discover'' loops that are
+constructed out of looping constructs in the language
+(such as Fortran's @code{DO}).  For some programs, ``discovering'' loops
+constructed out of lower-level constructs (such as @code{IF} and
+@code{GOTO}) can lead to generation of more optimal code
+than otherwise.} is done, so only loops written with @code{DO}
+benefit from loop optimizations, including---but not limited
+to---unrolling.  Loops written with @code{IF} and @code{GOTO} will not
+be recognized as such.  This option only unrolls indexed @code{DO}
+loops, not @code{DO WHILE} loops.
+
+@cindex -funroll-all-loops option
+@cindex options, -funroll-all-loops
+@cindex @code{DO WHILE}
+@item -funroll-all-loops
+@c DL: Check my understanding of -funroll-all-loops v. -funroll-loops is correct.
+Probably improves performance on code using @code{DO WHILE} loops by
+unrolling them in addition to indexed @code{DO} loops.  In the absence
+of @code{DO WHILE}, this option is equivalent to @code{-funroll-loops}
+but possibly slower.

+@xref{Directory Options,,Options for Directory Search}, for
+information on how @code{g77} processes the @code{INCLUDE} directive.
+
+However, the @code{INCLUDE} directive does not apply

+
+Therefore, any file that contains preprocessor directives
+(such as @code{#include}, @code{#define}, and @code{#if})
+must be included via the @code{#include} directive, not
+via the @code{INCLUDE} directive.
+Therefore, any file containing preprocessor directives,

+
+@node Directory Options
+@section Options for Directory Search
+@cindex directory options

+Therefore, when compiling Fortran programs, they are meaningful
+when the preprocessor is used.
+

+
+Note that @samp{-I@var{dir}} must be specified @emph{without} any

+@samp{-Ifoo/bar} is valid, but @samp{-I foo/bar}
+is rejected by the @code{g77} compiler (though the preprocessor supports

+@cindex code generation conventions
+@cindex options, code generation 
+@cindex run-time options
+
+These machine-independent options control the interface conventions

+
+Most of them have both positive and negative forms; the negative form
+of @samp{-ffoo} would be @samp{-fno-foo}.  In the table below, only
+one of the forms is listed---the one which is not the default.  You

+
+@table @code
+@cindex -fno-automatic option
+@cindex options, -fno-automatic
+@item -fno-automatic
+@cindex SAVE statement
+@cindex statements, SAVE
+Treat each program unit as if the @code{SAVE} statement was specified
+for every local variable and array referenced in it.
+Does not affect common blocks.
+(Some Fortran compilers provide this option under
+the name @samp{-static}.)
+
+@cindex -finit-local-zero option
+@cindex options, -finit-local-zero
+@item -finit-local-zero
+@cindex DATA statement
+@cindex statements, DATA
+@cindex initialization of local variables
+@cindex variables, initialization of
+@cindex uninitialized variables
+@cindex variables, uninitialized
+Specify that variables and arrays that are local to a program unit
+(not in a common block and not passed as an argument) are to be initialized
+to binary zeros.
+
+Since there is a run-time penalty for initialization of variables
+that are not given the @code{SAVE} attribute, it might be a
+good idea to also use @samp{-fno-automatic} with @samp{-finit-local-zero}.
+
+@cindex -fno-f2c option
+@cindex options, -fno-f2c
+@item -fno-f2c
+@cindex @code{f2c} compatibility
+@cindex compatibility, @code{f2c}
+Do not generate code designed to be compatible with code generated
+by @code{f2c}; use the GNU calling conventions instead.
+
+The @code{f2c} calling conventions require functions that return
+type @code{REAL(KIND=1)} to actually return the C type @code{double},
+and functions that return type @code{COMPLEX} to return the
+values via an extra argument in the calling sequence that points
+to where to store the return value.
+Under the GNU calling conventions, such functions simply return
+their results as they would in GNU C---@code{REAL(KIND=1)} functions
+return the C type @code{float}, and @code{COMPLEX} functions
+return the GNU C type @code{complex} (or its @code{struct}
+equivalent).
+
+This does not affect the generation of code that interfaces with the
+@code{libg2c} library.
+
+However, because the @code{libg2c} library uses @code{f2c}
+calling conventions, @code{g77} rejects attempts to pass
+intrinsics implemented by routines in this library as actual
+arguments when @samp{-fno-f2c} is used, to avoid bugs when
+they are actually called by code expecting the GNU calling
+conventions to work.
+
+For example, @samp{INTRINSIC ABS;CALL FOO(ABS)} is
+rejected when @samp{-fno-f2c} is in force.
+(Future versions of the @code{g77} run-time library might
+offer routines that provide GNU-callable versions of the
+routines that implement the @code{f2c}-callable intrinsics
+that may be passed as actual arguments, so that
+valid programs need not be rejected when @samp{-fno-f2c}
+is used.)
+
+@strong{Caution:} If @samp{-fno-f2c} is used when compiling any
+source file used in a program, it must be used when compiling
+@emph{all} Fortran source files used in that program.
+
+@c seems kinda dumb to tell people about an option they can't use -- jcb
+@c then again, we want users building future-compatible libraries with it.
+@cindex -ff2c-library option
+@cindex options, -ff2c-library
+@item -ff2c-library
+Specify that use of @code{libg2c} (or the original @code{libf2c})
+is required.
+This is the default for the current version of @code{g77}.
+
+Currently it is not
+valid to specify @samp{-fno-f2c-library}.
+This option is provided so users can specify it in shell
+scripts that build programs and libraries that require the
+@code{libf2c} library, even when being compiled by future
+versions of @code{g77} that might otherwise default to
+generating code for an incompatible library.
+
+@cindex -fno-underscoring option
+@cindex options, -fno-underscoring
+@item -fno-underscoring
+@cindex underscores
+@cindex symbol names, underscores
+@cindex transforming symbol names
+@cindex symbol names, transforming
+Do not transform names of entities specified in the Fortran
+source file by appending underscores to them.
+
+With @samp{-funderscoring} in effect, @code{g77} appends two underscores
+to names with underscores and one underscore to external names with
+no underscores.  (@code{g77} also appends two underscores to internal
+names with underscores to avoid naming collisions with external names.
+The @samp{-fno-second-underscore} option disables appending of the
+second underscore in all cases.)
+
+This is done to ensure compatibility with code produced by many
+UNIX Fortran compilers, including @code{f2c}, which perform the
+same transformations.
+
+Use of @samp{-fno-underscoring} is not recommended unless you are
+experimenting with issues such as integration of (GNU) Fortran into
+existing system environments (vis-a-vis existing libraries, tools, and
+so on).
+
+For example, with @samp{-funderscoring}, and assuming other defaults like
+@samp{-fcase-lower} and that @samp{j()} and @samp{max_count()} are
+external functions while @samp{my_var} and @samp{lvar} are local variables,
+a statement like
+
+@smallexample
+I = J() + MAX_COUNT (MY_VAR, LVAR)
+@end smallexample
+
+@noindent
+is implemented as something akin to:
+
+@smallexample
+i = j_() + max_count__(&my_var__, &lvar);
+@end smallexample
+
+With @samp{-fno-underscoring}, the same statement is implemented as:
+
+@smallexample
+i = j() + max_count(&my_var, &lvar);
+@end smallexample
+
+Use of @samp{-fno-underscoring} allows direct specification of
+user-defined names while debugging and when interfacing @code{g77}-compiled
+code with other languages.
+
+Note that just because the names match does @emph{not} mean that the
+interface implemented by @code{g77} for an external name matches the
+interface implemented by some other language for that same name.
+That is, getting code produced by @code{g77} to link to code produced
+by some other compiler using this or any other method can be only a
+small part of the overall solution---getting the code generated by
+both compilers to agree on issues other than naming can require
+significant effort, and, unlike naming disagreements, linkers normally
+cannot detect disagreements in these other areas.
+
+Also, note that with @samp{-fno-underscoring}, the lack of appended
+underscores introduces the very real possibility that a user-defined
+external name will conflict with a name in a system library, which
+could make finding unresolved-reference bugs quite difficult in some
+cases---they might occur at program run time, and show up only as
+buggy behavior at run time.
+
+In future versions of @code{g77}, we hope to improve naming and linking
+issues so that debugging always involves using the names as they appear
+in the source, even if the names as seen by the linker are mangled to
+prevent accidental linking between procedures with incompatible
+interfaces.
+
+@cindex -fno-second-underscore option
+@cindex options, -fno-second-underscore
+@item -fno-second-underscore
+@cindex underscores
+@cindex symbol names, underscores
+@cindex transforming symbol names
+@cindex symbol names, transforming
+Do not append a second underscore to names of entities specified
+in the Fortran source file.
+
+This option has no effect if @samp{-fno-underscoring} is
+in effect.
+
+Otherwise, with this option, an external name such as @samp{MAX_COUNT}
+is implemented as a reference to the link-time external symbol
+@samp{max_count_}, instead of @samp{max_count__}.
+
+@cindex -fno-ident option
+@cindex options, -fno-ident
+@item -fno-ident
+Ignore the @samp{#ident} directive.
+
+@cindex -fzeros option
+@cindex options, -fzeros
+@item -fzeros
+Treat initial values of zero as if they were any other value.
+
+As of version 0.5.18, @code{g77} normally treats @code{DATA} and
+other statements that are used to specify initial values of zero
+for variables and arrays as if no values were actually specified,
+in the sense that no diagnostics regarding multiple initializations
+are produced.
+
+This is done to speed up compiling of programs that initialize
+large arrays to zeros.
+
+Use @samp{-fzeros} to revert to the simpler, slower behavior
+that can catch multiple initializations by keeping track of
+all initializations, zero or otherwise.
+
+@emph{Caution:} Future versions of @code{g77} might disregard this option
+(and its negative form, the default) or interpret it somewhat
+differently.
+The interpretation changes will affect only non-standard
+programs; standard-conforming programs should not be affected.
+
+@cindex -fdebug-kludge option
+@cindex options, -fdebug-kludge
+@item -fdebug-kludge
+Emit information on @code{COMMON} and @code{EQUIVALENCE} members
+that might help users of debuggers work around lack of proper debugging
+information on such members.
+
+As of version 0.5.19, @code{g77} offers this option to emit
+information on members of aggregate areas to help users while debugging.
+This information consists of establishing the type and contents of each
+such member so that, when a debugger is asked to print the contents,
+the printed information provides rudimentary debugging information.
+This information identifies the name of the aggregate area (either the
+@code{COMMON} block name, or the @code{g77}-assigned name for the
+@code{EQUIVALENCE} name) and the offset, in bytes, of the member from
+the beginning of the area.
+
+Using @code{gdb}, this information is not coherently displayed in the Fortran
+language mode, so temporarily switching to the C language mode to display the
+information is suggested.
+Use @samp{set language c} and @samp{set language fortran} to accomplish this.
+
+For example:
+
+@smallexample
+      COMMON /X/A,B
+      EQUIVALENCE (C,D)
+      CHARACTER XX*50
+      EQUIVALENCE (I,XX(20:20))

+back end sees arithmetic on the real and imaginary components.
+To make @code{g77} more portable to systems where @code{complex}
+support in the @code{gcc} back end is particularly troublesome,
+@code{g77} now defaults to performing the same kinds of emulations
+done by these other front ends.
+
+Use @samp{-fno-emulate-complex} to try the @code{complex} support
+in the @code{gcc} back end, in case it works and produces faster
+programs.
+So far, all the known bugs seem to involve compile-time crashes,
+rather than the generation of incorrect code.
+
+Use of this option should not affect how Fortran code compiled
+by @code{g77} works in terms of its interfaces to other code,
+e.g. that compiled by @code{f2c}.
+
+@emph{Caution:} Future versions of @code{g77} are likely to change
+the default for this option to
+@samp{-fno-emulate-complex}, and perhaps someday ignore both forms
+of this option.
+
+Also, it is possible that use of the @samp{-fno-emulate-complex} option
+could result in incorrect code being silently produced by @code{g77}.
+But, this is generally true of compilers anyway, so, as usual, test
+the programs you compile before assuming they are working.

+@emph{Version info:}
+These options are not supported by
+versions of @code{g77} based on @code{gcc} version 2.8.
+
+These options specify to what degree aliasing
+(overlap)
+is permitted between
+arguments (passed as pointers) and @code{COMMON} (external, or
+public) storage.
+
+The default for Fortran code, as mandated by the FORTRAN 77 and
+Fortran 90 standards, is @samp{-fargument-noalias-global}.
+The default for code written in the C language family is
+@samp{-fargument-alias}.
+
+Note that, on some systems, compiling with @samp{-fforce-addr} in
+effect can produce more optimal code when the default aliasing
+options are in effect (and when optimization is enabled).

+Disable diagnostics about inter-procedural
+analysis problems, such as disagreements about the
+type of a function or a procedure's argument,
+that might cause a compiler crash when attempting
+to inline a reference to a procedure within a
+program unit.
+(The diagnostics themselves are still produced, but
+as warnings, unless @samp{-Wno-globals} is specified,
+in which case no relevant diagnostics are produced.)
+
+Further, this option disables such inlining, to
+avoid compiler crashes resulting from incorrect
+code that would otherwise be diagnosed.
+
+As such, this option might be quite useful when
+compiling existing, ``working'' code that happens
+to have a few bugs that do not generally show
+themselves, but @code{g77} exposes via a
+diagnostic.
+
+Use of this option therefore has the effect of
+instructing @code{g77} to behave more like it did
+up through version 0.5.19.1, when it paid little or
+no attention to disagreements between program units
+about a procedure's type and argument information,
+and when it performed no inlining of procedures
+(except statement functions).
+
+Without this option, @code{g77} defaults to performing
+the potentially inlining procedures as it started doing
+in version 0.5.20, but as of version 0.5.21, it also
+diagnoses disagreements that might cause such inlining
+to crash the compiler.

+@code{g77}'s version of @code{libf2c} separates out
+the setting of global state
+(such as command-line arguments and signal handling)
+from @file{main.o} into distinct, new library
+archive members.
+
+This should make it easier to write portable applications
+that have their own (non-Fortran) @code{main()} routine
+properly set up the @code{libf2c} environment, even
+when @code{libf2c} (now @code{libg2c}) is a shared library.
+
+@item
+The @code{g77} command now expects the run-time library
+to be named @code{libg2c.a} instead of @code{libf2c.a},
+to ensure that a version other than the one built and
+installed as part of the same @code{g77} version is picked up.
+
+@item
+Some diagnostics have been changed from warnings to errors,
+to prevent inadvertent use of the resulting, probably buggy,
+programs.
+These mostly include diagnostics about use of unsupported features
+in the @code{OPEN}, @code{INQUIRE}, @code{READ}, and
+@code{WRITE} statements,
+and about truncations of various sorts of constants.
+@end itemize
+
+@heading In 0.5.24 and @code{egcs} 1.1 (versus 0.5.23):
+@itemize @bullet
+@item
+@code{g77} now treats @samp{%LOC(@var{expr})} and
+@samp{LOC(@var{expr})} as ``ordinary'' expressions
+when they are used as arguments in procedure calls.
+This change applies only to global (filewide) analysis,
+making it consistent with
+how @code{g77} actually generates code
+for these cases.
+
+Previously, @code{g77} treated these expressions
+as denoting special ``pointer'' arguments
+for the purposes of filewide analysis.
+
+@item
+The @code{g77} driver now ensures that @samp{-lg2c}
+is specified in the link phase prior to any
+occurrence of @samp{-lm}.
+This prevents accidentally linking to a routine
+in the SunOS4 @samp{-lm} library
+when the generated code wants to link to the one
+in @code{libf2c} (@code{libg2c}).
+
+@item
+@code{g77} emits more debugging information when
+@samp{-g} is used.
+
+This new information allows, for example,
+@kbd{which __g77_length_a} to be used in @code{gdb}
+to determine the type of the phantom length argument
+supplied with @samp{CHARACTER} variables.
+
+This information pertains to internally-generated
+type, variable, and other information,
+not to the longstanding deficiencies vis-a-vis
+@samp{COMMON} and @samp{EQUIVALENCE}.
+
+@item
+The F90 @samp{Date_and_Time} intrinsic now is
+supported.
+
+@item
+The F90 @samp{System_Clock} intrinsic allows
+the optional arguments (except for the @samp{Count}
+argument) to be omitted.

+Fix @code{libU77} routines that accept file and other names

+Some programs might use names that clash with

+
+This type is wide enough
+(holds the same number of bits)
+as the character-pointer type on the machine.
+
+On most machines, this won't make a difference,
+whereas, on Alphas and other systems with 64-bit pointers,

+GNU Fortran supports a variety of extensions to, and dialects

+Its primary base is the ANSI FORTRAN 77 standard, currently available on

+@uref{http://www.fortran.com/fortran/F77_std/rjcnf0001.html}
+or as monolithic text at
+@uref{http://www.fortran.com/fortran/F77_std/f77_std.html}.
+It offers some extensions that are popular among users
+of UNIX @code{f77} and @code{f2c} compilers, some that
+are popular among users of other compilers (such as Digital
+products), some that are popular among users of the
+newer Fortran 90 standard, and some that are introduced
+by GNU Fortran.
+
+@cindex textbooks

+@cindex direction of language development
+@cindex features, language
+@cindex language features
+
+The purpose of the following description of the GNU Fortran
+language is to promote wide portability of GNU Fortran programs.
+
+GNU Fortran is an evolving language, due to the
+fact that @code{g77} itself is in beta test.
+Some current features of the language might later
+be redefined as dialects of Fortran supported by @code{g77}
+when better ways to express these features are added to @code{g77},
+for example.
+Such features would still be supported by
+@code{g77}, but would be available only when
+one or more command-line options were used.
+
+The GNU Fortran @emph{language} is distinct from the
+GNU Fortran @emph{compilation system} (@code{g77}).
+
+For example, @code{g77} supports various dialects of
+Fortran---in a sense, these are languages other than
+GNU Fortran---though its primary
+purpose is to support the GNU Fortran language, which also is
+described in its documentation and by its implementation.
+
+On the other hand, non-GNU compilers might offer
+support for the GNU Fortran language, and are encouraged
+to do so.
+
+Currently, the GNU Fortran language is a fairly fuzzy object.
+It represents something of a cross between what @code{g77} accepts
+when compiling using the prevailing defaults and what this
+document describes as being part of the language.
+
+Future versions of @code{g77} are expected to clarify the
+definition of the language in the documentation.
+Often, this will mean adding new features to the language, in the form
+of both new documentation and new support in @code{g77}.
+However, it might occasionally mean removing a feature
+from the language itself to ``dialect'' status.
+In such a case, the documentation would be adjusted
+to reflect the change, and @code{g77} itself would likely be changed
+to require one or more command-line options to continue supporting
+the feature.
+
+The development of the GNU Fortran language is intended to strike
+a balance between:
+
+@itemize @bullet
+@item
+Serving as a mostly-upwards-compatible language from the
+de facto UNIX Fortran dialect as supported by @code{f77}.
+
+@item
+Offering new, well-designed language features.
+Attributes of such features include
+not making existing code any harder to read
+(for those who might be unaware that the new
+features are not in use) and
+not making state-of-the-art
+compilers take longer to issue diagnostics,
+among others.
+
+@item
+Supporting existing, well-written code without gratuitously
+rejecting non-standard constructs, regardless of the origin
+of the code (its dialect).
+
+@item
+Offering default behavior and command-line options to reduce
+and, where reasonable, eliminate the need for programmers to make
+any modifications to code that already works in existing
+production environments.
+
+@item
+Diagnosing constructs that have different meanings in different
+systems, languages, and dialects, while offering clear,
+less ambiguous ways to express each of the different meanings
+so programmers can change their code appropriately.
+@end itemize
+
+One of the biggest practical challenges for the developers of the
+GNU Fortran language is meeting the sometimes contradictory demands
+of the above items.
+
+For example, a feature might be widely used in one popular environment,
+but the exact same code that utilizes that feature might not work
+as expected---perhaps it might mean something entirely different---in
+another popular environment.
+
+Traditionally, Fortran compilers---even portable ones---have solved this
+problem by simply offering the appropriate feature to users of
+the respective systems.
+This approach treats users of various Fortran systems and dialects
+as remote ``islands'', or camps, of programmers, and assume that these
+camps rarely come into contact with each other (or,
+especially, with each other's code).
+
+Project GNU takes a radically different approach to software and language
+design, in that it assumes that users of GNU software do not necessarily
+care what kind of underlying system they are using, regardless
+of whether they are using software (at the user-interface
+level) or writing it (for example, writing Fortran or C code).
+
+As such, GNU users rarely need consider just what kind of underlying
+hardware (or, in many cases, operating system) they are using at any
+particular time.
+They can use and write software designed for a general-purpose,
+widely portable, heterogenous environment---the GNU environment.
+
+In line with this philosophy, GNU Fortran must evolve into a product
+that is widely ported and portable not only in the sense that it can
+be successfully built, installed, and run by users, but in the larger
+sense that its users can use it in the same way, and expect largely the
+same behaviors from it, regardless of the kind of system they are using
+at any particular time.
+
+This approach constrains the solutions @code{g77} can use to resolve
+conflicts between various camps of Fortran users.
+If these two camps disagree about what a particular construct should
+mean, @code{g77} cannot simply be changed to treat that particular construct as
+having one meaning without comment (such as a warning), lest the users
+expecting it to have the other meaning are unpleasantly surprised that
+their code misbehaves when executed.
+
+The use of the ASCII backslash character in character constants is
+an excellent (and still somewhat unresolved) example of this kind of
+controversy.
+@xref{Backslash in Constants}.
+Other examples are likely to arise in the future, as @code{g77} developers
+strive to improve its ability to accept an ever-wider variety of existing
+Fortran code without requiring significant modifications to said code.
+
+Development of GNU Fortran is further constrained by the desire
+to avoid requiring programmers to change their code.
+This is important because it allows programmers, administrators,
+and others to more faithfully evaluate and validate @code{g77}
+(as an overall product and as new versions are distributed)
+without having to support multiple versions of their programs
+so that they continue to work the same way on their existing
+systems (non-GNU perhaps, but possibly also earlier versions
+of @code{g77}).

+Chapter 1 of that document otherwise serves as the basis

+
+The definition of the GNU Fortran language is akin to that of
+the ANSI FORTRAN 77 language in that it does not generally require
+conforming implementations to diagnose cases where programs do
+not conform to the language.
+
+However, @code{g77} as a compiler is being developed in a way that
+is intended to enable it to diagnose such cases in an easy-to-understand
+manner.
+
+A program that conforms to the GNU Fortran language should, when
+compiled, linked, and executed using a properly installed @code{g77}
+system, perform as described by the GNU Fortran language definition.
+Reasons for different behavior include, among others:
+
+@itemize @bullet
+@item
+Use of resources (memory---heap, stack, and so on; disk space; CPU
+time; etc.) exceeds those of the system.
+
+@item
+Range and/or precision of calculations required by the program
+exceeds that of the system.
+
+@item
+Excessive reliance on behaviors that are system-dependent
+(non-portable Fortran code).
+
+@item
+Bugs in the program.
+
+@item
+Bug in @code{g77}.
+
+@item
+Bugs in the system.
+@end itemize
+
+Despite these ``loopholes'', the availability of a clear specification
+of the language of programs submitted to @code{g77}, as this document
+is intended to provide, is considered an important aspect of providing
+a robust, clean, predictable Fortran implementation.
+
+The definition of the GNU Fortran language, while having no special
+legal status, can therefore be viewed as a sort of contract, or agreement.
+This agreement says, in essence, ``if you write a program in this language,
+and run it in an environment (such as a @code{g77} system) that supports
+this language, the program should behave in a largely predictable way''.

+
+In this chapter, ``must'' denotes a requirement, ``may'' denotes permission,
+and ``must not'' and ``may not'' denote prohibition.
+Terms such as ``might'', ``should'', and ``can'' generally add little or
+nothing in the way of weight to the GNU Fortran language itself,
+but are used to explain or illustrate the language.
+
+For example:
+
+@display
+``The @code{FROBNITZ} statement must precede all executable
+statements in a program unit, and may not specify any dummy
+arguments.  It may specify local or common variables and arrays.
+Its use should be limited to portions of the program designed to
+be non-portable and system-specific, because it might cause the
+containing program unit to behave quite differently on different
+systems.''
+@end display
+
+Insofar as the GNU Fortran language is specified,
+the requirements and permissions denoted by the above sample statement
+are limited to the placement of the statement and the kinds of
+things it may specify.
+The rest of the statement---the content regarding non-portable portions
+of the program and the differing behavior of program units containing
+the @code{FROBNITZ} statement---does not pertain the GNU Fortran
+language itself.
+That content offers advice and warnings about the @code{FROBNITZ}
+statement.
+
+@emph{Remember:} The GNU Fortran language definition specifies
+both what constitutes a valid GNU Fortran program and how,
+given such a program, a valid GNU Fortran implementation is
+to interpret that program.
+
+It is @emph{not} incumbent upon a valid GNU Fortran implementation
+to behave in any particular way, any consistent way, or any
+predictable way when it is asked to interpret input that is
+@emph{not} a valid GNU Fortran program.
+
+Such input is said to have @dfn{undefined} behavior when
+interpreted by a valid GNU Fortran implementation, though
+an implementation may choose to specify behaviors for some
+cases of inputs that are not valid GNU Fortran programs.
+
+Other notation used herein is that of the GNU texinfo format,

+in lowercase---uppercase is used in this manual as a
+means to readily distinguish keywords and sample Fortran-related
+text from the prose in this document.
+
+@item
+Portions of actual sample program, input, or output text
+look like this: @samp{Actual program text}.
+
+Generally, uppercase is used for all Fortran-specific and
+Fortran-related text, though this does not always include
+literal text within Fortran code.
+
+For example: @samp{PRINT *, 'My name is Bob'}.
+
+@item
+A metasyntactic variable---that is, a name used in this document
+to serve as a placeholder for whatever text is used by the
+user or programmer--appears as shown in the following example:
+
+``The @code{INTEGER @var{ivar}} statement specifies that
+@var{ivar} is a variable or array of type @code{INTEGER}.''
+
+In the above example, any valid text may be substituted for

+apply to a specific instance, as long as the same text is

+
+(Corresponds to Section 3.2 of ANSI X3.9-1978 FORTRAN 77.)
+
+The way a Fortran compiler views source files depends entirely on the
+implementation choices made for the compiler, since those choices
+are explicitly left to the implementation by the published Fortran
+standards.
+
+The GNU Fortran language mandates a view applicable to UNIX-like
+text files---files that are made up of an arbitrary number of lines,
+each with an arbitrary number of characters (sometimes called stream-based
+files).
+
+This view does not apply to types of files that are specified as
+having a particular number of characters on every single line (sometimes
+referred to as record-based files).
+
+Because a ``line in a program unit is a sequence of 72 characters'',
+to quote X3.9-1978, the GNU Fortran language specifies that a
+stream-based text file is translated to GNU Fortran lines as follows:
+
+@itemize @bullet
+@item
+A newline in the file is the character that represents the end of
+a line of text to the underlying system.
+For example, on ASCII-based systems, a newline is the @key{NL}
+character, which has ASCII value 12 (decimal).
+
+@item
+Each newline in the file serves to end the line of text that precedes
+it (and that does not contain a newline).
+
+@item
+The end-of-file marker (@code{EOF}) also serves to end the line
+of text that precedes it (and that does not contain a newline).
+
+@item
+@cindex blanks (spaces)
+Any line of text that is shorter than 72 characters is padded to that length
+with spaces (called ``blanks'' in the standard).
+
+@item
+Any line of text that is longer than 72 characters is truncated to that
+length, but the truncated remainder must consist entirely of spaces.
+
+@item
+Characters other than newline and the GNU Fortran character set
+are invalid.
+@end itemize
+
+For the purposes of the remainder of this description of the GNU
+Fortran language, the translation described above has already
+taken place, unless otherwise specified.
+
+The result of the above translation is that the source file appears,
+in terms of the remainder of this description of the GNU Fortran language,
+as if it had an arbitrary
+number of 72-character lines, each character being among the GNU Fortran
+character set.
+
+For example, if the source file itself has two newlines in a row,
+the second newline becomes, after the above translation, a single
+line containing 72 spaces.

+@end itemize
+
+A continuation character is any character of the GNU Fortran character set

+in column 6, or a digit (@samp{0} through @samp{9}) in column
+7 through 72 of a line that has only spaces to the left of that
+digit.
+
+The continuation character is ignored as far as the content of
+the statement is concerned.
+
+The GNU Fortran language places no limit on the number of
+continuation lines in a statement.
+In practice, the limit depends on a variety of factors, such as
+available memory, statement content, and so on, but no
+GNU Fortran system may impose an arbitrary limit.

+@node Statements
+@subsection Statements
+
+(Corresponds to Section 3.3 of ANSI X3.9-1978 FORTRAN 77.)

+
+Statements may be separated using the semicolon (@samp{;}), except
+that the logical @code{IF} and non-construct @code{WHERE} statements
+may not be separated from subsequent statements using only a semicolon
+as statement separator.
+
+The @code{END PROGRAM}, @code{END SUBROUTINE}, @code{END FUNCTION},
+and @code{END BLOCK DATA} statements are alternatives to the @code{END}
+statement.
+These alternatives may be written as normal statements---they are not
+subject to the restrictions of the @code{END} statement.
+
+However, no statement other than @code{END} may have an initial line
+that appears to be an @code{END} statement---even @code{END PROGRAM},

+The semicolon is followed by the label for the statement,
+which in turn follows the label.
+
+@item
+The label must be no more than five digits in length.
+
+@item
+The first digit of the label for the statement is not
+the first non-space character on a line.
+Otherwise, that character is treated as a continuation
+character.

+@node Order
+@subsection Order of Statements and Lines

+Generally, @code{DATA} statements may precede executable statements.
+However, specification statements pertaining to any entities
+initialized by a @code{DATA} statement must precede that @code{DATA}
+statement.
+For example,
+after @samp{DATA I/1/}, @samp{INTEGER I} is not permitted, but
+@samp{INTEGER J} is permitted.
+
+The last line of a program unit may be an @code{END} statement,

+
+@node INCLUDE
+@subsection Including Source Text
+@cindex INCLUDE
+
+Additional source text may be included in the processing of
+the source file via the @code{INCLUDE} directive:
+
+@example
+INCLUDE @var{filename}
+@end example
+
+@noindent
+The source text to be included is identified by @var{filename},
+which is a literal GNU Fortran character constant.
+The meaning and interpretation of @var{filename} depends on the
+implementation, but typically is a filename.
+
+(@code{g77} treats it as a filename that it searches for
+in the current directory and/or directories specified
+via the @samp{-I} command-line option.)
+
+The effect of the @code{INCLUDE} directive is as if the
+included text directly replaced the directive in the source
+file prior to interpretation of the program.
+Included text may itself use @code{INCLUDE}.
+The depth of nested @code{INCLUDE} references depends on
+the implementation, but typically is a positive integer.
+
+This virtual replacement treats the statements and @code{INCLUDE}
+directives in the included text as syntactically distinct from
+those in the including text.
+
+Therefore, the first non-comment line of the included text
+must not be a continuation line.
+The included text must therefore have, after the non-comment
+lines, either an initial line (statement), an @code{INCLUDE}
+directive, or nothing (the end of the included text).
+
+Similarly, the including text may end the @code{INCLUDE}
+directive with a semicolon or the end of the line, but it
+cannot follow an @code{INCLUDE} directive at the end of its
+line with a continuation line.
+Thus, the last statement in an included text may not be
+continued.
+
+Any statements between two @code{INCLUDE} directives on the
+same line are treated as if they appeared in between the
+respective included texts.
+For example:
+
+@smallexample
+INCLUDE 'A'; PRINT *, 'B'; INCLUDE 'C'; END PROGRAM
+@end smallexample
+
+@noindent
+If the text included by @samp{INCLUDE 'A'} constitutes
+a @samp{PRINT *, 'A'} statement and the text included by
+@samp{INCLUDE 'C'} constitutes a @samp{PRINT *, 'C'} statement,
+then the output of the above sample program would be
+
+@example
+A
+B
+C
+@end example
+
+@noindent
+(with suitable allowances for how an implementation defines
+its handling of output).
+
+Included text must not include itself directly or indirectly,
+regardless of whether the @var{filename} used to reference
+the text is the same.
+
+Note that @code{INCLUDE} is @emph{not} a statement.
+As such, it is neither a non-executable or executable
+statement.
+However, if the text it includes constitutes one or more
+executable statements, then the placement of @code{INCLUDE}
+is subject to effectively the same restrictions as those
+on executable statements.
+
+An @code{INCLUDE} directive may be continued across multiple
+lines as if it were a statement.
+This permits long names to be used for @var{filename}.

+language.
+Chapter 4 of that document otherwise serves as the basis
+for the relevant aspects of GNU Fortran.)
+
+To more concisely express the appropriate types for
+entities, this document uses the more concise
+Fortran 90 nomenclature such as @code{INTEGER(KIND=1)}
+instead of the more traditional, but less portably concise,
+byte-size-based nomenclature such as @code{INTEGER*4},
+wherever reasonable.
+
+When referring to generic types---in contexts where the
+specific precision and range of a type are not important---this
+document uses the generic type names @code{INTEGER}, @code{LOGICAL},
+@code{REAL}, @code{COMPLEX}, and @code{CHARACTER}.
+
+In some cases, the context requires specification of a
+particular type.
+This document uses the @samp{KIND=} notation to accomplish
+this throughout, sometimes supplying the more traditional
+notation for clarification, though the traditional notation
+might not work the same way on all GNU Fortran implementations.
+
+Use of @samp{KIND=} makes this document more concise because
+@code{g77} is able to define values for @samp{KIND=} that
+have the same meanings on all systems, due to the way the
+Fortran 90 standard specifies these values are to be used.
+
+(In particular, that standard permits an implementation to
+arbitrarily assign nonnegative values.
+There are four distinct sets of assignments: one to the @code{CHARACTER}
+type; one to the @code{INTEGER} type; one to the @code{LOGICAL} type;
+and the fourth to both the @code{REAL} and @code{COMPLEX} types.
+Implementations are free to assign these values in any order,
+leave gaps in the ordering of assignments, and assign more than
+one value to a representation.)
+
+This makes @samp{KIND=} values superior to the values used
+in non-standard statements such as @samp{INTEGER*4}, because
+the meanings of the values in those statements vary from machine
+to machine, compiler to compiler, even operating system to
+operating system.
+
+However, use of @samp{KIND=} is @emph{not} generally recommended
+when writing portable code (unless, for example, the code is
+going to be compiled only via @code{g77}, which is a widely
+ported compiler).
+GNU Fortran does not yet have adequate language constructs to
+permit use of @samp{KIND=} in a fashion that would make the
+code portable to Fortran 90 implementations; and, this construct
+is known to @emph{not} be accepted by many popular FORTRAN 77
+implementations, so it cannot be used in code that is to be ported
+to those.
+
+The distinction here is that this document is able to use
+specific values for @samp{KIND=} to concisely document the
+types of various operations and operands.
+
+A Fortran program should use the FORTRAN 77 designations for the
+appropriate GNU Fortran types---such as @code{INTEGER} for
+@code{INTEGER(KIND=1)}, @code{REAL} for @code{REAL(KIND=1)},
+and @code{DOUBLE COMPLEX} for @code{COMPLEX(KIND=2)}---and,
+where no such designations exist, make use of appropriate
+techniques (preprocessor macros, parameters, and so on)
+to specify the types in a fashion that may be easily adjusted
+to suit each particular implementation to which the program
+is ported.
+(These types generally won't need to be adjusted for ports of
+@code{g77}.)

+
+@item

+
+The generic types shown above are referred to in this document
+using only their generic type names.
+Such references usually indicate that any specific type (kind)
+of that generic type is valid.
+
+For example, a context described in this document as accepting
+the @code{COMPLEX} type also is likely to accept the
+@code{DOUBLE COMPLEX} type.
+
+The GNU Fortran language supports three ways to specify
+a specific kind of a generic type.

+
+@node Double Notation
+@subsubsection Double Notation
+
+The GNU Fortran language supports two uses of the keyword
+@code{DOUBLE} to specify a specific kind of type:
+
+@itemize @bullet
+@item
+@code{DOUBLE PRECISION}, equivalent to @code{REAL(KIND=2)}
+
+@item
+@code{DOUBLE COMPLEX}, equivalent to @code{COMPLEX(KIND=2)}
+@end itemize
+
+Use one of the above forms where a type name is valid.
+
+While use of this notation is popular, it doesn't scale
+well in a language or dialect rich in intrinsic types,
+as is the case for the GNU Fortran language (especially
+planned future versions of it).
+
+After all, one rarely sees type names such as @samp{DOUBLE INTEGER},
+@samp{QUADRUPLE REAL}, or @samp{QUARTER INTEGER}.
+Instead, @code{INTEGER*8}, @code{REAL*16}, and @code{INTEGER*1}
+often are substituted for these, respectively, even though they
+do not always have the same meanings on all systems.
+(And, the fact that @samp{DOUBLE REAL} does not exist as such
+is an inconsistency.)
+
+Therefore, this document uses ``double notation'' only on occasion
+for the benefit of those readers who are accustomed to it.
+
+@node Star Notation
+@subsubsection Star Notation
+@cindex *@var{n} notation
+
+The following notation specifies the storage size for a type:
+
+@smallexample
+@var{generic-type}*@var{n}
+@end smallexample
+
+@noindent
+@var{generic-type} must be a generic type---one of
+@code{INTEGER}, @code{REAL}, @code{COMPLEX}, @code{LOGICAL},
+or @code{CHARACTER}.
+@var{n} must be one or more digits comprising a decimal
+integer number greater than zero.
+
+Use the above form where a type name is valid.
+
+The @samp{*@var{n}} notation specifies that the amount of storage
+occupied by variables and array elements of that type is @var{n}
+times the storage occupied by a @code{CHARACTER*1} variable.
+
+This notation might indicate a different degree of precision and/or
+range for such variables and array elements, and the functions that
+return values of types using this notation.
+It does not limit the precision or range of values of that type
+in any particular way---use explicit code to do that.
+
+Further, the GNU Fortran language requires no particular values
+for @var{n} to be supported by an implementation via the @samp{*@var{n}}
+notation.
+@code{g77} supports @code{INTEGER*1} (as @code{INTEGER(KIND=3)})
+on all systems, for example,
+but not all implementations are required to do so, and @code{g77}
+is known to not support @code{REAL*1} on most (or all) systems.
+
+As a result, except for @var{generic-type} of @code{CHARACTER},
+uses of this notation should be limited to isolated
+portions of a program that are intended to handle system-specific
+tasks and are expected to be non-portable.
+
+(Standard FORTRAN 77 supports the @samp{*@var{n}} notation for
+only @code{CHARACTER}, where it signifies not only the amount
+of storage occupied, but the number of characters in entities
+of that type.
+However, almost all Fortran compilers have supported this
+notation for generic types, though with a variety of meanings
+for @var{n}.)
+
+Specifications of types using the @samp{*@var{n}} notation
+always are interpreted as specifications of the appropriate
+types described in this document using the @samp{KIND=@var{n}}
+notation, described below.
+
+While use of this notation is popular, it doesn't serve well
+in the context of a widely portable dialect of Fortran, such as
+the GNU Fortran language.
+
+For example, even on one particular machine, two or more popular
+Fortran compilers might well disagree on the size of a type
+declared @code{INTEGER*2} or @code{REAL*16}.
+Certainly there
+is known to be disagreement over such things among Fortran
+compilers on @emph{different} systems.
+
+Further, this notation offers no elegant way to specify sizes
+that are not even multiples of the ``byte size'' typically
+designated by @code{INTEGER*1}.
+Use of ``absurd'' values (such as @code{INTEGER*1000}) would
+certainly be possible, but would perhaps be stretching the original
+intent of this notation beyond the breaking point in terms
+of widespread readability of documentation and code making use
+of it.
+
+Therefore, this document uses ``star notation'' only on occasion
+for the benefit of those readers who are accustomed to it.
+
+@node Kind Notation
+@subsubsection Kind Notation
+@cindex KIND= notation
+
+The following notation specifies the kind-type selector of a type:
+
+@smallexample
+@var{generic-type}(KIND=@var{n})
+@end smallexample
+
+@noindent
+Use the above form where a type name is valid.
+
+@var{generic-type} must be a generic type---one of
+@code{INTEGER}, @code{REAL}, @code{COMPLEX}, @code{LOGICAL},
+or @code{CHARACTER}.
+@var{n} must be an integer initialization expression that
+is a positive, nonzero value.
+
+Programmers are discouraged from writing these values directly
+into their code.
+Future versions of the GNU Fortran language will offer
+facilities that will make the writing of code portable
+to @code{g77} @emph{and} Fortran 90 implementations simpler.
+
+However, writing code that ports to existing FORTRAN 77
+implementations depends on avoiding the @samp{KIND=} construct.
+
+The @samp{KIND=} construct is thus useful in the context
+of GNU Fortran for two reasons:
+
+@itemize @bullet
+@item
+It provides a means to specify a type in a fashion that
+is portable across all GNU Fortran implementations (though
+not other FORTRAN 77 and Fortran 90 implementations).
+
+@item
+It provides a sort of Rosetta stone for this document to use
+to concisely describe the types of various operations and
+operands.
+@end itemize
+
+The values of @var{n} in the GNU Fortran language are
+assigned using a scheme that:
+
+@itemize @bullet
+@item
+Attempts to maximize the ability of readers
+of this document to quickly familiarize themselves
+with assignments for popular types
+
+@item
+Provides a unique value for each specific desired
+meaning
+
+@item
+Provides a means to automatically assign new values so
+they have a ``natural'' relationship to existing values,
+if appropriate, or, if no such relationship exists, will
+not interfere with future values assigned on the basis
+of such relationships
+
+@item
+Avoids using values that are similar to values used
+in the existing, popular @samp{*@var{n}} notation,
+to prevent readers from expecting that these implied
+correspondences work on all GNU Fortran implementations
+@end itemize
+
+The assignment system accomplishes this by assigning
+to each ``fundamental meaning'' of a specific type a
+unique prime number.
+Combinations of fundamental meanings---for example, a type
+that is two times the size of some other type---are assigned
+values of @var{n} that are the products of the values for
+those fundamental meanings.
+
+A prime value of @var{n} is never given more than one fundamental
+meaning, to avoid situations where some code or system
+cannot reasonably provide those meanings in the form of a
+single type.
+
+The values of @var{n} assigned so far are:
+
+@table @code
+@item KIND=0
+This value is reserved for future use.
+
+The planned future use is for this value to designate,
+explicitly, context-sensitive kind-type selection.
+For example, the expression @samp{1D0 * 0.1_0} would
+be equivalent to @samp{1D0 * 0.1D0}.
+
+@item KIND=1
+This corresponds to the default types for
+@code{REAL}, @code{INTEGER}, @code{LOGICAL}, @code{COMPLEX},
+and @code{CHARACTER}, as appropriate.
+
+These are the ``default'' types described in the Fortran 90 standard,
+though that standard does not assign any particular @samp{KIND=}
+value to these types.
+
+(Typically, these are @code{REAL*4}, @code{INTEGER*4},
+@code{LOGICAL*4}, and @code{COMPLEX*8}.)
+
+@item KIND=2
+This corresponds to types that occupy twice as much
+storage as the default types.
+@code{REAL(KIND=2)} is @code{DOUBLE PRECISION} (typically @code{REAL*8}),
+@code{COMPLEX(KIND=2)} is @code{DOUBLE COMPLEX} (typically @code{COMPLEX*16}),
+
+These are the ``double precision'' types described in the Fortran 90
+standard,
+though that standard does not assign any particular @samp{KIND=}
+value to these types.
+
+@var{n} of 4 thus corresponds to types that occupy four times
+as much storage as the default types, @var{n} of 8 to types that
+occupy eight times as much storage, and so on.
+
+The @code{INTEGER(KIND=2)} and @code{LOGICAL(KIND=2)} types
+are not necessarily supported by every GNU Fortran implementation.
+
+@item KIND=3
+This corresponds to types that occupy as much
+storage as the default @code{CHARACTER} type,
+which is the same effective type as @code{CHARACTER(KIND=1)}
+(making that type effectively the same as @code{CHARACTER(KIND=3)}).
+
+(Typically, these are @code{INTEGER*1} and @code{LOGICAL*1}.)
+
+@var{n} of 6 thus corresponds to types that occupy twice as
+much storage as the @var{n}=3 types, @var{n} of 12 to types
+that occupy four times as much storage, and so on.
+
+These are not necessarily supported by every GNU Fortran
+implementation.
+
+@item KIND=5
+This corresponds to types that occupy half the
+storage as the default (@var{n}=1) types.
+
+(Typically, these are @code{INTEGER*2} and @code{LOGICAL*2}.)
+
+@var{n} of 25 thus corresponds to types that occupy one-quarter
+as much storage as the default types.
+
+These are not necessarily supported by every GNU Fortran
+implementation.
+
+@item KIND=7
+@cindex pointers
+This is valid only as @code{INTEGER(KIND=7)} and
+denotes the @code{INTEGER} type that has the smallest
+storage size that holds a pointer on the system.
+
+A pointer representable by this type is capable of uniquely
+addressing a @code{CHARACTER*1} variable, array, array element,
+or substring.
+
+(Typically this is equivalent to @code{INTEGER*4} or,
+on 64-bit systems, @code{INTEGER*8}.
+In a compatible C implementation, it typically would
+be the same size and semantics of the C type @code{void *}.)
+@end table
+
+Note that these are @emph{proposed} correspondences and might change
+in future versions of @code{g77}---avoid writing code depending
+on them while @code{g77}, and therefore the GNU Fortran language
+it defines, is in beta testing.
+
+Values not specified in the above list are reserved to
+future versions of the GNU Fortran language.
+
+Implementation-dependent meanings will be assigned new,
+unique prime numbers so as to not interfere with other
+implementation-dependent meanings, and offer the possibility
+of increasing the portability of code depending on such
+types by offering support for them in other GNU Fortran
+implementations.
+
+Other meanings that might be given unique values are:
+
+@itemize @bullet
+@item
+Types that make use of only half their storage size for
+representing precision and range.
+
+For example, some compilers offer options that cause
+@code{INTEGER} types to occupy the amount of storage
+that would be needed for @code{INTEGER(KIND=2)} types, but the
+range remains that of @code{INTEGER(KIND=1)}.
+
+@item
+The IEEE single floating-point type.
+
+@item
+Types with a specific bit pattern (endianness), such as the
+little-endian form of @code{INTEGER(KIND=1)}.
+These could permit, conceptually, use of portable code and
+implementations on data files written by existing systems.
+@end itemize
+
+Future @emph{prime} numbers should be given meanings in as incremental
+a fashion as possible, to allow for flexibility and
+expressiveness in combining types.
+
+For example, instead of defining a prime number for little-endian
+IEEE doubles, one prime number might be assigned the meaning
+``little-endian'', another the meaning ``IEEE double'', and the
+value of @var{n} for a little-endian IEEE double would thus
+naturally be the product of those two respective assigned values.
+(It could even be reasonable to have IEEE values result from the
+products of prime values denoting exponent and fraction sizes
+and meanings, hidden bit usage, availability and representations
+of special values such as subnormals, infinities, and Not-A-Numbers
+(NaNs), and so on.)
+
+This assignment mechanism, while not inherently required for
+future versions of the GNU Fortran language, is worth using
+because it could ease management of the ``space'' of supported
+types much easier in the long run.
+
+The above approach suggests a mechanism for specifying inheritance
+of intrinsic (built-in) types for an entire, widely portable
+product line.
+It is certainly reasonable that, unlike programmers of other languages
+offering inheritance mechanisms that employ verbose names for classes
+and subclasses, along with graphical browsers to elucidate the
+relationships, Fortran programmers would employ
+a mechanism that works by multiplying prime numbers together
+and finding the prime factors of such products.
+
+Most of the advantages for the above scheme have been explained
+above.
+One disadvantage is that it could lead to the defining,
+by the GNU Fortran language, of some fairly large prime numbers.
+This could lead to the GNU Fortran language being declared
+``munitions'' by the United States Department of Defense.

+@subsection The @code{%LOC()} Construct
+@cindex %LOC() construct
+
+@example
+%LOC(@var{arg})
+@end example
+
+The @code{%LOC()} construct is an expression
+that yields the value of the location of its argument,
+@var{arg}, in memory.
+The size of the type of the expression depends on the system---typically,
+it is equivalent to either @code{INTEGER(KIND=1)} or @code{INTEGER(KIND=2)},
+though it is actually type @code{INTEGER(KIND=7)}.
+
+The argument to @code{%LOC()} must be suitable as the
+left-hand side of an assignment statement.
+That is, it may not be a general expression involving
+operators such as addition, subtraction, and so on,
+nor may it be a constant.
+
+Use of @code{%LOC()} is recommended only for code that
+is accessing facilities outside of GNU Fortran, such as
+operating system or windowing facilities.
+It is best to constrain such uses to isolated portions of
+a program---portions that deal specifically and exclusively
+with low-level, system-dependent facilities.
+Such portions might well provide a portable interface for
+use by the program as a whole, but are themselves not
+portable, and should be thoroughly tested each time they
+are rebuilt using a new compiler or version of a compiler.
+
+Do not depend on @code{%LOC()} returning a pointer that
+can be safely used to @emph{define} (change) the argument.
+While this might work in some circumstances, it is hard
+to predict whether it will continue to work when a program
+(that works using this unsafe behavior)
+is recompiled using different command-line options or
+a different version of @code{g77}.
+
+Generally, @code{%LOC()} is safe when used as an argument
+to a procedure that makes use of the value of the corresponding
+dummy argument only during its activation, and only when
+such use is restricted to referencing (reading) the value
+of the argument to @code{%LOC()}.
+
+@emph{Implementation Note:} Currently, @code{g77} passes
+arguments (those not passed using a construct such as @code{%VAL()})
+by reference or descriptor, depending on the type of
+the actual argument.
+Thus, given @samp{INTEGER I}, @samp{CALL FOO(I)} would
+seem to mean the same thing as @samp{CALL FOO(%VAL(%LOC(I)))}, and
+in fact might compile to identical code.
+
+However, @samp{CALL FOO(%VAL(%LOC(I)))} emphatically means
+``pass, by value, the address of @samp{I} in memory''.
+While @samp{CALL FOO(I)} might use that same approach in a
+particular version of @code{g77}, another version or compiler
+might choose a different implementation, such as copy-in/copy-out,
+to effect the desired behavior---and which will therefore not
+necessarily compile to the same code as would
+@samp{CALL FOO(%VAL(%LOC(I)))}
+using the same version or compiler.

+@cindex MIL-STD 1753
+
+The @code{DO WHILE} statement, a feature of both the MIL-STD 1753 and
+Fortran 90 standards, is provided by the GNU Fortran language.
+The Fortran 90 ``do forever'' statement comprising just @code{DO} is

+
+@node END DO
+@subsection END DO
+@cindex END DO
+@cindex MIL-STD 1753
+
+The @code{END DO} statement is provided by the GNU Fortran language.
+
+This statement is used in one of two ways:
+
+@itemize @bullet
+@item
+The Fortran 90 meaning, in which it specifies the termination
+point of a single @code{DO} loop started with a @code{DO} statement
+that specifies no termination label.
+
+@item
+The MIL-STD 1753 meaning, in which it specifies the termination
+point of one or more @code{DO} loops, all of which start with a
+@code{DO} statement that specify the label defined for the
+@code{END DO} statement.
+
+This kind of @code{END DO} statement is merely a synonym for
+@code{CONTINUE}, except it is permitted only when the statement
+is labeled and a target of one or more labeled @code{DO} loops.
+
+It is expected that this use of @code{END DO} will be removed from
+the GNU Fortran language in the future, though it is likely that
+it will long be supported by @code{g77} as a dialect form.
+@end itemize
+
+@node Construct Names
+@subsection Construct Names
+@cindex construct names
+
+The GNU Fortran language supports construct names as defined
+by the Fortran 90 standard.
+These names are local to the program unit and are defined
+as follows:
+
+@smallexample
+@var{construct-name}: @var{block-statement}
+@end smallexample
+
+@noindent
+Here, @var{construct-name} is the construct name itself;
+its definition is connoted by the single colon (@samp{:}); and
+@var{block-statement} is an @code{IF}, @code{DO},
+or @code{SELECT CASE} statement that begins a block.
+
+A block that is given a construct name must also specify the
+same construct name in its termination statement:
+
+@example
+END @var{block} @var{construct-name}
+@end example
+
+@noindent
+Here, @var{block} must be @code{IF}, @code{DO}, or @code{SELECT},
+as appropriate.
+
+@node CYCLE and EXIT
+@subsection The @code{CYCLE} and @code{EXIT} Statements
+
+The @code{CYCLE} and @code{EXIT} statements specify that
+the remaining statements in the current iteration of a
+particular active (enclosing) @code{DO} loop are to be skipped.
+
+@code{CYCLE} specifies that these statements are skipped,
+but the @code{END DO} statement that marks the end of the
+@code{DO} loop be executed---that is, the next iteration,
+if any, is to be started.
+If the statement marking the end of the @code{DO} loop is
+not @code{END DO}---in other words, if the loop is not
+a block @code{DO}---the @code{CYCLE} statement does not
+execute that statement, but does start the next iteration (if any).
+
+@code{EXIT} specifies that the loop specified by the
+@code{DO} construct is terminated.
+
+The @code{DO} loop affected by @code{CYCLE} and @code{EXIT}
+is the innermost enclosing @code{DO} loop when the following
+forms are used:
+
+@example
+CYCLE
+EXIT
+@end example
+
+Otherwise, the following forms specify the construct name
+of the pertinent @code{DO} loop:
+
+@example
+CYCLE @var{construct-name}
+EXIT @var{construct-name}
+@end example
+
+@code{CYCLE} and @code{EXIT} can be viewed as glorified @code{GO TO}
+statements.
+However, they cannot be easily thought of as @code{GO TO} statements
+in obscure cases involving FORTRAN 77 loops.
+For example:
+
+@smallexample
+      DO 10 I = 1, 5
+      DO 10 J = 1, 5
+         IF (J .EQ. 5) EXIT
+      DO 10 K = 1, 5
+         IF (K .EQ. 3) CYCLE
+10    PRINT *, 'I=', I, ' J=', J, ' K=', K
+20    CONTINUE
+@end smallexample
+
+@noindent
+In particular, neither the @code{EXIT} nor @code{CYCLE} statements
+above are equivalent to a @code{GO TO} statement to either label
+@samp{10} or @samp{20}.
+
+To understand the effect of @code{CYCLE} and @code{EXIT} in the
+above fragment, it is helpful to first translate it to its equivalent
+using only block @code{DO} loops:
+
+@smallexample
+      DO I = 1, 5
+         DO J = 1, 5
+            IF (J .EQ. 5) EXIT
+            DO K = 1, 5
+               IF (K .EQ. 3) CYCLE
+10             PRINT *, 'I=', I, ' J=', J, ' K=', K
+            END DO
+         END DO
+      END DO
+20    CONTINUE
+@end smallexample
+
+Adding new labels allows translation of @code{CYCLE} and @code{EXIT}
+to @code{GO TO} so they may be more easily understood by programmers
+accustomed to FORTRAN coding:
+
+@smallexample
+      DO I = 1, 5
+         DO J = 1, 5
+            IF (J .EQ. 5) GOTO 18
+            DO K = 1, 5
+               IF (K .EQ. 3) GO TO 12
+10             PRINT *, 'I=', I, ' J=', J, ' K=', K
+12          END DO
+         END DO
+18    END DO
+20    CONTINUE
+@end smallexample
+
+@noindent
+Thus, the @code{CYCLE} statement in the innermost loop skips over
+the @code{PRINT} statement as it begins the next iteration of the
+loop, while the @code{EXIT} statement in the middle loop ends that
+loop but @emph{not} the outermost loop.

+@cindex intrinsics, generic
+
+The ANSI FORTRAN 77 language defines generic and specific
+intrinsics.
+In short, the distinctions are:
+
+@itemize @bullet
+@item
+@emph{Specific} intrinsics have
+specific types for their arguments and a specific return
+type.
+
+@item
+@emph{Generic} intrinsics are treated,
+on a case-by-case basis in the program's source code,
+as one of several possible specific intrinsics.
+
+Typically, a generic intrinsic has a return type that
+is determined by the type of one or more of its arguments.
+@end itemize
+
+The GNU Fortran language generalizes these concepts somewhat,
+especially by providing intrinsic subroutines and generic
+intrinsics that are treated as either a specific intrinsic subroutine
+or a specific intrinsic function (e.g. @code{SECOND}).
+
+However, GNU Fortran avoids generalizing this concept to
+the point where existing code would be accepted as meaning
+something possibly different than what was intended.
+
+For example, @code{ABS} is a generic intrinsic, so all working
+code written using @code{ABS} of an @code{INTEGER} argument
+expects an @code{INTEGER} return value.
+Similarly, all such code expects that @code{ABS} of an @code{INTEGER*2}
+argument returns an @code{INTEGER*2} return value.
+
+Yet, @code{IABS} is a @emph{specific} intrinsic that accepts only
+an @code{INTEGER(KIND=1)} argument.
+Code that passes something other than an @code{INTEGER(KIND=1)}
+argument to @code{IABS} is not valid GNU Fortran code, because
+it is not clear what the author intended.
+
+For example, if @samp{J} is @code{INTEGER(KIND=6)}, @samp{IABS(J)}
+is not defined by the GNU Fortran language, because the programmer
+might have used that construct to mean any of the following, subtly
+different, things:
+
+@itemize @bullet
+@item
+Convert @samp{J} to @code{INTEGER(KIND=1)} first
+(as if @samp{IABS(INT(J))} had been written).
+
+@item
+Convert the result of the intrinsic to @code{INTEGER(KIND=1)}
+(as if @samp{INT(ABS(J))} had been written).
+
+@item
+No conversion (as if @samp{ABS(J)} had been written).
+@end itemize
+
+The distinctions matter especially when types and values wider than
+@code{INTEGER(KIND=1)} (such as @code{INTEGER(KIND=2)}), or when
+operations performing more ``arithmetic'' than absolute-value, are involved.
+
+The following sample program is not a valid GNU Fortran program, but
+might be accepted by other compilers.
+If so, the output is likely to be revealing in terms of how a given
+compiler treats intrinsics (that normally are specific) when they
+are given arguments that do not conform to their stated requirements:

+
+No future version of the GNU Fortran language
+will likely permit specific intrinsic invocations with wrong-typed
+arguments (such as @code{IDIM} in the above example), since
+it has been determined that disagreements exist among
+many production compilers on the interpretation of
+such invocations.
+These disagreements strongly suggest that Fortran programmers,
+and certainly existing Fortran programs, disagree about the
+meaning of such invocations.
+
+The first version of @samp{JCB002} didn't accommodate some compilers'
+treatment of @samp{INT(I1-I2)} where @samp{I1} and @samp{I2} are
+@code{INTEGER*2}.
+In such a case, these compilers apparently convert both
+operands to @code{INTEGER*4} and then do an @code{INTEGER*4} subtraction,
+instead of doing an @code{INTEGER*2} subtraction on the
+original values in @samp{I1} and @samp{I2}.
+
+However, the results of the careful analyses done on the outputs
+of programs compiled by these various compilers show that they
+all implement either @samp{Interp 1} or @samp{Interp 2} above.
+
+Specifically, it is believed that the new version of @samp{JCB002}
+above will confirm that:
+
+@itemize @bullet
+@item
+Digital Semiconductor (``DEC'') Alpha OSF/1, HP-UX 10.0.1, AIX 3.2.5
+@code{f77} compilers all implement @samp{Interp 1}.
+
+@item
+IRIX 5.3 @code{f77} compiler implements @samp{Interp 2}.
+
+@item
+Solaris 2.5, SunOS 4.1.3, DECstation ULTRIX 4.3,
+and IRIX 6.1 @code{f77} compilers all implement @samp{Interp 3}.

+If you get different results than the above for the stated
+compilers, or have results for other compilers that might be
+worth adding to the above list, please let us know the details
+(compiler product, version, machine, results, and so on).

+@cindex REAL intrinsic
+@cindex intrinsics, REAL
+@cindex AIMAG intrinsic
+@cindex intrinsics, AIMAG
+
+The GNU Fortran language disallows @code{REAL(@var{expr})}
+and @code{AIMAG(@var{expr})},
+where @var{expr} is any @code{COMPLEX} type other than @code{COMPLEX(KIND=1)},
+except when they are used in the following way:
+
+@example
+REAL(REAL(@var{expr}))
+REAL(AIMAG(@var{expr}))
+@end example
+
+@noindent
+The above forms explicitly specify that the desired effect
+is to convert the real or imaginary part of @var{expr}, which might
+be some @code{REAL} type other than @code{REAL(KIND=1)},
+to type @code{REAL(KIND=1)},
+and have that serve as the value of the expression.
+
+The GNU Fortran language offers clearly named intrinsics to extract the
+real and imaginary parts of a complex entity without any
+conversion:
+
+@example
+REALPART(@var{expr})
+IMAGPART(@var{expr})
+@end example
+
+To express the above using typical extended FORTRAN 77,
+use the following constructs
+(when @var{expr} is @code{COMPLEX(KIND=2)}):
+
+@example
+DBLE(@var{expr})
+DIMAG(@var{expr})
+@end example
+
+The FORTRAN 77 language offers no way
+to explicitly specify the real and imaginary parts of a complex expression of
+arbitrary type, apparently as a result of requiring support for
+only one @code{COMPLEX} type (@code{COMPLEX(KIND=1)}).
+The concepts of converting an expression to type @code{REAL(KIND=1)} and
+of extracting the real part of a complex expression were
+thus ``smooshed'' by FORTRAN 77 into a single intrinsic, since
+they happened to have the exact same effect in that language
+(due to having only one @code{COMPLEX} type).
+
+@emph{Note:} When @samp{-ff90} is in effect,
+@code{g77} treats @samp{REAL(@var{expr})}, where @var{expr} is of
+type @code{COMPLEX}, as @samp{REALPART(@var{expr})},
+whereas with @samp{-fugly-complex -fno-f90} in effect, it is
+treated as @samp{REAL(REALPART(@var{expr}))}.

+@subsection @code{CMPLX()} of @code{DOUBLE PRECISION}
+@cindex CMPLX intrinsic
+@cindex intrinsics, CMPLX
+
+In accordance with Fortran 90 and at least some (perhaps all)
+other compilers, the GNU Fortran language defines @code{CMPLX()}
+as always returning a result that is type @code{COMPLEX(KIND=1)}.
+
+This means @samp{CMPLX(D1,D2)}, where @samp{D1} and @samp{D2}
+are @code{REAL(KIND=2)} (@code{DOUBLE PRECISION}), is treated as:
+
+@example
+CMPLX(SNGL(D1), SNGL(D2))
+@end example
+
+(It was necessary for Fortran 90 to specify this behavior
+for @code{DOUBLE PRECISION} arguments, since that is
+the behavior mandated by FORTRAN 77.)
+
+The GNU Fortran language also provides the @code{DCMPLX()} intrinsic,
+which is provided by some FORTRAN 77 compilers to construct
+a @code{DOUBLE COMPLEX} entity from of @code{DOUBLE PRECISION}
+operands.
+However, this solution does not scale well when more @code{COMPLEX} types
+(having various precisions and ranges) are offered by Fortran implementations.
+
+Fortran 90 extends the @code{CMPLX()} intrinsic by adding
+an extra argument used to specify the desired kind of complex
+result.
+However, this solution is somewhat awkward to use, and
+@code{g77} currently does not support it.
+
+The GNU Fortran language provides a simple way to build a complex
+value out of two numbers, with the precise type of the value
+determined by the types of the two numbers (via the usual
+type-promotion mechanism):
+
+@example
+COMPLEX(@var{real}, @var{imag})
+@end example
+
+When @var{real} and @var{imag} are the same @code{REAL} types, @code{COMPLEX()}
+performs no conversion other than to put them together to form a
+complex result of the same (complex version of real) type.

+(Corresponds to Section 15.10 of ANSI X3.9-1978 FORTRAN 77.)
+
+The GNU Fortran language adds various functions, subroutines, types,
+and arguments to the set of intrinsic functions in ANSI FORTRAN 77.
+The complete set of intrinsics supported by the GNU Fortran language
+is described below.
+
+Note that a name is not treated as that of an intrinsic if it is
+specified in an @code{EXTERNAL} statement in the same program unit;
+if a command-line option is used to disable the groups to which
+the intrinsic belongs; or if the intrinsic is not named in an
+@code{INTRINSIC} statement and a command-line option is used to
+hide the groups to which the intrinsic belongs.
+
+So, it is recommended that any reference in a program unit to
+an intrinsic procedure that is not a standard FORTRAN 77
+intrinsic be accompanied by an appropriate @code{INTRINSIC}
+statement in that program unit.
+This sort of defensive programming makes it more
+likely that an implementation will issue a diagnostic rather
+than generate incorrect code for such a reference.
+
+The terminology used below is based on that of the Fortran 90
+standard, so that the text may be more concise and accurate:

+@samp{scalar} means the argument must not be an array (must
+be a variable or array element, or perhaps a constant if expressions
+are permitted).
+
+@item
+@samp{DIMENSION(4)} means the argument must be an array having 4 elements.
+
+@item
+@code{INTENT(IN)} means the argument must be an expression
+(such as a constant or a variable that is defined upon invocation
+of the intrinsic).
+
+@item

+invocation of the intrinsic (that is, must not be a constant nor
+an expression involving operators other than array reference and
+substring reference).

+
+GNU Fortran accepts programs written in either fixed form or
+free form.
+
+Fixed form
+corresponds to ANSI FORTRAN 77 (plus popular extensions, such as
+allowing tabs) and Fortran 90's fixed form.
+
+Free form corresponds to
+Fortran 90's free form (though possibly not entirely up-to-date, and
+without complaining about some things that for which Fortran 90 requires
+diagnostics, such as the spaces in the constant in @samp{R = 3 . 1}).
+
+The way a Fortran compiler views source files depends entirely on the
+implementation choices made for the compiler, since those choices
+are explicitly left to the implementation by the published Fortran
+standards.
+GNU Fortran currently tries to be somewhat like a few popular compilers
+(@code{f2c}, Digital (``DEC'') Fortran, and so on), though a cleaner default
+definition along with more
+flexibility offered by command-line options is likely to be offered
+in version 0.6.

+@node Carriage Returns
+@subsection Carriage Returns
+@cindex carriage returns
+
+Carriage returns (@samp{\r}) in source lines are ignored.
+This is somewhat different from @code{f2c}, which seems to treat them as
+spaces outside character/Hollerith constants, and encodes them as @samp{\r}
+inside such constants.
+
+@node Tabs
+@subsection Tabs
+@cindex tab characters
+
+A source line with a @key{TAB} character anywhere in it is treated as
+entirely significant---however long it is---instead of ending in
+column 72 (for fixed-form source) or 132 (for free-form source).
+This also is different from @code{f2c}, which encodes tabs as
+@samp{\t} (the ASCII @key{TAB} character) inside character
+and Hollerith constants, but nevertheless seems to treat the column
+position as if it had been affected by the canonical tab positioning.
+
+@code{g77} effectively
+translates tabs to the appropriate number of spaces (a la the default

+than (currently) noting whether a tab was found on a line and using this
+information to decide how to interpret the length of the line and continued
+constants.
+
+Note that this default behavior probably will change for version 0.6,
+when it will presumably be available via a command-line option.
+The default as of version 0.6 is planned to be a ``pure visual''
+model, where tabs are immediately
+converted to spaces and otherwise have no effect, so the way a typical
+user sees source lines produces a consistent result no matter how the
+spacing in those source lines is actually implemented via tabs, spaces,
+and trailing tabs/spaces before newline.
+Command-line options are likely to be added to specify whether all or
+just-tabbed lines are to be extended to 132 or full input-line length,
+and perhaps even an option will be added to specify the truncated-line
+behavior to which some Digital compilers default (and which affects
+the way continued character/Hollerith constants are interpreted).

+
+Also, such readers might think they can use @samp{//} to start

+
+GNU Fortran offers the programmer way too much flexibility in deciding
+how source files are to be treated vis-a-vis uppercase and lowercase
+characters.
+There are 66 useful settings that affect case sensitivity, plus 10
+settings that are nearly useless, with the remaining 116 settings
+being either redundant or useless.
+
+None of these settings have any effect on the contents of comments
+(the text after a @samp{c} or @samp{C} in Column 1, for example)
+or of character or Hollerith constants.
+Note that things like the @samp{E} in the statement
+@samp{CALL FOO(3.2E10)} and the @samp{TO} in @samp{ASSIGN 10 TO LAB}
+are considered built-in keywords, and so are affected by
+these settings.
+
+Low-level switches are identified in this section as follows:
+
+@itemize @w{}
+@item A
+Source Case Conversion:
+
+@itemize @w{}
+@item 0
+Preserve (see Note 1)
+@item 1
+Convert to Upper Case
+@item 2
+Convert to Lower Case
+@end itemize
+
+@item B
+Built-in Keyword Matching:
+
+@itemize @w{}
+@item 0
+Match Any Case (per-character basis)
+@item 1
+Match Upper Case Only
+@item 2
+Match Lower Case Only
+@item 3
+Match InitialCaps Only (see tables for spellings)
+@end itemize
+
+@item C
+Built-in Intrinsic Matching:
+
+@itemize @w{}
+@item 0
+Match Any Case (per-character basis)
+@item 1
+Match Upper Case Only
+@item 2
+Match Lower Case Only
+@item 3
+Match InitialCaps Only (see tables for spellings)
+@end itemize
+
+@item D
+User-defined Symbol Possibilities (warnings only):
+
+@itemize @w{}
+@item 0
+Allow Any Case (per-character basis)
+@item 1
+Allow Upper Case Only
+@item 2
+Allow Lower Case Only
+@item 3
+Allow InitialCaps Only (see Note 2)
+@end itemize
+@end itemize
+
+Note 1: @code{g77} eventually will support @code{NAMELIST} in a manner that is
+consistent with these source switches---in the sense that input will be
+expected to meet the same requirements as source code in terms
+of matching symbol names and keywords (for the exponent letters).
+
+Currently, however, @code{NAMELIST} is supported by @code{libg2c},
+which uppercases @code{NAMELIST} input and symbol names for matching.
+This means not only that @code{NAMELIST} output currently shows symbol
+(and keyword) names in uppercase even if lower-case source
+conversion (option A2) is selected, but that @code{NAMELIST} cannot be
+adequately supported when source case preservation (option A0)
+is selected.
+
+If A0 is selected, a warning message will be
+output for each @code{NAMELIST} statement to this effect.
+The behavior
+of the program is undefined at run time if two or more symbol names
+appear in a given @code{NAMELIST} such that the names are identical
+when converted to upper case (e.g. @samp{NAMELIST /X/ VAR, Var, var}).
+For complete and total elegance, perhaps there should be a warning
+when option A2 is selected, since the output of NAMELIST is currently
+in uppercase but will someday be lowercase (when a @code{libg77} is written),
+but that seems to be overkill for a product in beta test.
+
+Note 2: Rules for InitialCaps names are:
+
+@itemize --
+@item
+Must be a single uppercase letter, @strong{or}
+@item
+Must start with an uppercase letter and contain at least one
+lowercase letter.
+@end itemize
+
+So @samp{A}, @samp{Ab}, @samp{ABc}, @samp{AbC}, and @samp{Abc} are
+valid InitialCaps names, but @samp{AB}, @samp{A2}, and @samp{ABC} are
+not.
+Note that most, but not all, built-in names meet these
+requirements---the exceptions are some of the two-letter format
+specifiers, such as @samp{BN} and @samp{BZ}.
+
+Here are the names of the corresponding command-line options:
+
+@smallexample
+A0: -fsource-case-preserve
+A1: -fsource-case-upper
+A2: -fsource-case-lower

+make most useful programs impossible: Numbers 67 and 72 warn about
+@emph{any} user-defined symbol names (such as @samp{SUBROUTINE FOO});
+Numbers
+68 and 73 warn about any user-defined symbol names longer than one
+character that don't have at least one non-alphabetic character after
+the first;
+Numbers 69 and 74 disallow any references to intrinsics;
+and Numbers 70, 71, 75, and 76 are combinations of the restrictions in
+67+69, 68+69, 72+74, and 73+74, respectively.
+
+All redundant combinations are shown in the above tables anyplace
+where more than one setting is shown for a low-level switch.
+For example, @samp{B0-2-} means either setting 0 or 2 is valid for switch B.
+The ``proper'' setting in such a case is the one that copies the setting
+of switch A---any other setting might slightly reduce the speed of
+the compiler, though possibly to an unmeasurable extent.
+
+All remaining combinations are useless in that they prevent successful
+compilation of non-null source files (source files with something other
+than comments).

+someday, and is considered a VXT Fortran feature.
+
+The @samp{-fvxt} option generally specifies that, where

+The features enabled by @samp{-ff90} are intended to be those that,
+when @samp{-ff90} is not specified, would have another
+meaning to @code{g77}---usually meaning something invalid in the
+GNU Fortran language.
+
+So, the purpose of @samp{-ff90} is not to specify whether @code{g77} is
+to gratuitously reject Fortran 90 constructs.
+The @samp{-pedantic} option specified with @samp{-fno-f90} is intended
+to do that, although its implementation is certainly incomplete at
+this point.
+
+When @samp{-ff90} is specified:
+
+@itemize @bullet
+@item
+The type of @samp{REAL(@var{expr})} and @samp{AIMAG(@var{expr})},
+where @var{expr} is @code{COMPLEX} type,
+is the same type as the real part of @var{expr}.
+
+For example, assuming @samp{Z} is type @code{COMPLEX(KIND=2)},
+@samp{REAL(Z)} would return a value of type @code{REAL(KIND=2)},
+not of type @code{REAL(KIND=1)}, since @samp{-ff90} is specified.

+REAL A(N)
+@dots{}

+where @samp{A} is not listed in any @code{ENTRY} statement,
+and thus is not a dummy argument.
+
+@item
+The commas in @samp{READ (5), I} and @samp{WRITE (10), J}.
+
+These commas are disallowed by FORTRAN 77, but, while strictly
+superfluous, are syntactically elegant,
+especially given that commas are required in statements such
+as @samp{READ 99, I} and @samp{PRINT *, J}.
+Many compilers permit the superfluous commas for this reason.
+
+@item
+@code{DOUBLE COMPLEX}, either explicitly or implicitly.
+
+An explicit use of this type is via a @code{DOUBLE COMPLEX} or
+@code{IMPLICIT DOUBLE COMPLEX} statement, for examples.
+
+An example of an implicit use is the expression @samp{C*D},
+where @samp{C} is @code{COMPLEX(KIND=1)}
+and @samp{D} is @code{DOUBLE PRECISION}.
+This expression is prohibited by ANSI FORTRAN 77
+because the rules of promotion would suggest that it
+produce a @code{DOUBLE COMPLEX} result---a type not
+provided for by that standard.

+@cindex assumed-size arrays
+@cindex DIMENSION X(1)
+
+The @samp{-fugly-assumed} option enables
+the treatment of any array with a final dimension specified as @samp{1}
+as an assumed-size array, as if @samp{*} had been specified
+instead.
+
+For example, @samp{DIMENSION X(1)} is treated as if it
+had read @samp{DIMENSION X(*)} if @samp{X} is listed as
+a dummy argument in a preceding @code{SUBROUTINE}, @code{FUNCTION},
+or @code{ENTRY} statement in the same program unit.
+
+Use an explicit lower bound to avoid this interpretation.
+For example, @samp{DIMENSION X(1:1)} is never treated as if
+it had read @samp{DIMENSION X(*)} or @samp{DIMENSION X(1:*)}.
+Nor is @samp{DIMENSION X(2-1)} affected by this option,
+since that kind of expression is unlikely to have been
+intended to designate an assumed-size array.
+
+This option is used to prevent warnings being issued about apparent
+out-of-bounds reference such as @samp{X(2) = 99}.
+
+It also prevents the array from being used in contexts that
+disallow assumed-size arrays, such as @samp{PRINT *,X}.
+In such cases, a diagnostic is generated and the source file is
+not compiled.
+
+The construct affected by this option is used only in old code
+that pre-exists the widespread acceptance of adjustable and assumed-size
+arrays in the Fortran community.
+
+@emph{Note:} This option does not affect how @samp{DIMENSION X(1)} is
+treated if @samp{X} is listed as a dummy argument only
+@emph{after} the @code{DIMENSION} statement (presumably in
+an @code{ENTRY} statement).
+For example, @samp{-fugly-assumed} has no effect on the

+SUBROUTINE X
+REAL A(1)
+RETURN
+ENTRY Y(A)

+@node Ugly Complex Part Extraction

+
+The @samp{-fugly-complex} option enables

+intrinsics with arguments that are
+@code{COMPLEX} types other than @code{COMPLEX(KIND=1)}.
+
+With @samp{-ff90} in effect, these intrinsics return
+the unconverted real and imaginary parts (respectively)
+of their argument.
+
+With @samp{-fno-f90} in effect, these intrinsics convert
+the real and imaginary parts to @code{REAL(KIND=1)}, and return
+the result of that conversion.
+
+Due to this ambiguity, the GNU Fortran language defines
+these constructs as invalid, except in the specific
+case where they are entirely and solely passed as an
+argument to an invocation of the @code{REAL()} intrinsic.
+For example,
+
+@example
+REAL(REAL(Z))
+@end example
+
+@noindent
+is permitted even when @samp{Z} is @code{COMPLEX(KIND=2)}
+and @samp{-fno-ugly-complex} is in effect, because the

+
+The @samp{-fugly-comma} option enables use of a single trailing comma

+in a list of actual arguments to an external procedure,
+and use of an empty list of arguments to such a procedure
+to mean ``pass a single null argument''.
+
+@cindex omitting arguments
+@cindex arguments, omitting
+(Null arguments often are used in some procedure-calling
+schemes to indicate omitted arguments.)
+
+For example, @samp{CALL FOO(,)} means ``pass
+two null arguments'', rather than ``pass one null argument''.
+Also, @samp{CALL BAR()} means ``pass one null argument''.
+
+This construct is considered ``ugly'' because it does not
+provide an elegant way to pass a single null argument
+that is syntactically distinct from passing no arguments.
+That is, this construct changes the meaning of code that
+makes no use of the construct.
+
+So, with @samp{-fugly-comma} in force, @samp{CALL FOO()}
+and @samp{I = JFUNC()} pass a single null argument, instead
+of passing no arguments as required by the Fortran 77 and
+90 standards.
+
+@emph{Note:} Many systems gracefully allow the case
+where a procedure call passes one extra argument that the
+called procedure does not expect.
+
+So, in practice, there might be no difference in
+the behavior of a program that does @samp{CALL FOO()}
+or @samp{I = JFUNC()} and is compiled with @samp{-fugly-comma}
+in force as compared to its behavior when compiled
+with the default, @samp{-fno-ugly-comma}, in force,

+
+The above constructs are disabled by default because use

+Even existing Fortran code that uses that often turns out

+
+Some of this is due to differences among implementations as
+far as how @code{.TRUE.} and @code{.FALSE.} are encoded as

+@node Ugly Assigned Labels
+@subsection Ugly Assigned Labels
+@cindex ASSIGN statement

+@cindex assigned labels
+@cindex pointers
+
+The @samp{-fugly-assign} option forces @code{g77} to use the
+same storage for assigned labels as it would for a normal
+assignment to the same variable.
+
+For example, consider the following code fragment:
+
+@example
+I = 3
+ASSIGN 10 TO I
+@end example
+
+@noindent
+Normally, for portability and improved diagnostics, @code{g77}
+reserves distinct storage for a ``sibling'' of @samp{I}, used
+only for @code{ASSIGN} statements to that variable (along with
+the corresponding assigned-@code{GOTO} and assigned-@samp{FORMAT}-I/O
+statements that reference the variable).
+
+However, some code (that violates the ANSI FORTRAN 77 standard)
+attempts to copy assigned labels among variables involved with
+@code{ASSIGN} statements, as in:
+
+@example
+ASSIGN 10 TO I
+ISTATE(5) = I
+@dots{}
+J = ISTATE(ICUR)
+GOTO J
+@end example
+
+@noindent
+Such code doesn't work under @code{g77} unless @samp{-fugly-assign}
+is specified on the command-line, ensuring that the value of @code{I}
+referenced in the second line is whatever value @code{g77} uses
+to designate statement label @samp{10}, so the value may be
+copied into the @samp{ISTATE} array, later retrieved into a
+variable of the appropriate type (@samp{J}), and used as the target of
+an assigned-@code{GOTO} statement.
+
+@emph{Note:} To avoid subtle program bugs,
+when @samp{-fugly-assign} is specified,
+@code{g77} requires the type of variables
+specified in assigned-label contexts
+@emph{must} be the same type returned by @code{%LOC()}.
+On many systems, this type is effectively the same
+as @code{INTEGER(KIND=1)}, while, on others, it is
+effectively the same as @code{INTEGER(KIND=2)}.
+
+Do @emph{not} depend on @code{g77} actually writing valid pointers
+to these variables, however.
+While @code{g77} currently chooses that implementation, it might
+be changed in the future.

+
+@node Compiler Types
+@section Compiler Types
+@cindex types, of data
+@cindex data types
+
+Fortran implementations have a fair amount of freedom given them by the
+standard as far as how much storage space is used and how much precision
+and range is offered by the various types such as @code{LOGICAL(KIND=1)},
+@code{INTEGER(KIND=1)}, @code{REAL(KIND=1)}, @code{REAL(KIND=2)},
+@code{COMPLEX(KIND=1)}, and @code{CHARACTER}.
+Further, many compilers offer so-called @samp{*@var{n}} notation, but
+the interpretation of @var{n} varies across compilers and target architectures.
+
+The standard requires that @code{LOGICAL(KIND=1)}, @code{INTEGER(KIND=1)},
+and @code{REAL(KIND=1)}
+occupy the same amount of storage space, and that @code{COMPLEX(KIND=1)}
+and @code{REAL(KIND=2)} take twice as much storage space as @code{REAL(KIND=1)}.
+Further, it requires that @code{COMPLEX(KIND=1)}
+entities be ordered such that when a @code{COMPLEX(KIND=1)} variable is
+storage-associated (such as via @code{EQUIVALENCE})
+with a two-element @code{REAL(KIND=1)} array named @samp{R}, @samp{R(1)}
+corresponds to the real element and @samp{R(2)} to the imaginary
+element of the @code{COMPLEX(KIND=1)} variable.
+
+(Few requirements as to precision or ranges of any of these are
+placed on the implementation, nor is the relationship of storage sizes of
+these types to the @code{CHARACTER} type specified, by the standard.)
+
+@code{g77} follows the above requirements, warning when compiling
+a program requires placement of items in memory that contradict the
+requirements of the target architecture.
+(For example, a program can require placement of a @code{REAL(KIND=2)}
+on a boundary that is not an even multiple of its size, but still an
+even multiple of the size of a @code{REAL(KIND=1)} variable.
+On some target architectures, using the canonical
+mapping of Fortran types to underlying architectural types, such
+placement is prohibited by the machine definition or
+the Application Binary Interface (ABI) in force for
+the configuration defined for building @code{gcc} and @code{g77}.
+@code{g77} warns about such
+situations when it encounters them.)
+
+@code{g77} follows consistent rules for configuring the mapping between Fortran
+types, including the @samp{*@var{n}} notation, and the underlying architectural
+types as accessed by a similarly-configured applicable version of the
+@code{gcc} compiler.
+These rules offer a widely portable, consistent Fortran/C
+environment, although they might well conflict with the expectations of
+users of Fortran compilers designed and written for particular
+architectures.
+
+These rules are based on the configuration that is in force for the
+version of @code{gcc} built in the same release as @code{g77} (and
+which was therefore used to build both the @code{g77} compiler
+components and the @code{libg2c} run-time library):

+@cindex constants
+@cindex types, constants
+
+@code{g77} strictly assigns types to @emph{all} constants not
+documented as ``typeless'' (typeless constants including @samp{'1'Z},
+for example).
+Many other Fortran compilers attempt to assign types to typed constants
+based on their context.
+This results in hard-to-find bugs, nonportable
+code, and is not in the spirit (though it strictly follows the letter)
+of the 77 and 90 standards.
+
+@code{g77} might offer, in a future release, explicit constructs by
+which a wider variety of typeless constants may be specified, and/or

+@node Compiler Intrinsics
+@section Compiler Intrinsics

+@code{g77} offers an ever-widening set of intrinsics.
+Currently these all are procedures (functions and subroutines).

+Some of these intrinsics are unimplemented, but their names reserved
+to reduce future problems with existing code as they are implemented.
+Others are implemented as part of the GNU Fortran language, while
+yet others are provided for compatibility with other dialects of
+Fortran but are not part of the GNU Fortran language.
+
+To manage these distinctions, @code{g77} provides intrinsic @emph{groups},
+a facility that is simply an extension of the intrinsic groups provided
+by the GNU Fortran language.
+

+
+@node Intrinsic Groups
+@subsection Intrinsic Groups
+@cindex groups of intrinsics
+@cindex intrinsics, groups
+
+A given specific intrinsic belongs in one or more groups.
+Each group is deleted, disabled, hidden, or enabled
+by default or a command-line option.
+The meaning of each term follows.
+
+@table @b
+@cindex deleted intrinsics
+@cindex intrinsics, deleted
+@item Deleted
+No intrinsics are recognized as belonging to that group.
+
+@cindex disabled intrinsics
+@cindex intrinsics, disabled
+@item Disabled
+Intrinsics are recognized as belonging to the group, but
+references to them (other than via the @code{INTRINSIC} statement)
+are disallowed through that group.
+
+@cindex hidden intrinsics
+@cindex intrinsics, hidden
+@item Hidden
+Intrinsics in that group are recognized and enabled (if implemented)
+@emph{only} if the first mention of the actual name of an intrinsic
+in a program unit is in an @code{INTRINSIC} statement.
+
+@cindex enabled intrinsics
+@cindex intrinsics, enabled
+@item Enabled
+Intrinsics in that group are recognized and enabled (if implemented).
+@end table
+
+The distinction between deleting and disabling a group is illustrated
+by the following example.
+Assume intrinsic @samp{FOO} belongs only to group @samp{FGR}.
+If group @samp{FGR} is deleted, the following program unit will
+successfully compile, because @samp{FOO()} will be seen as a
+reference to an external function named @samp{FOO}:
+
+@example
+PRINT *, FOO()
+END
+@end example
+
+@noindent
+If group @samp{FGR} is disabled, compiling the above program will produce
+diagnostics, either because the @samp{FOO} intrinsic is improperly invoked
+or, if properly invoked, it is not enabled.
+To change the above program so it references an external function @samp{FOO}
+instead of the disabled @samp{FOO} intrinsic,
+add the following line to the top:
+
+@example
+EXTERNAL FOO
+@end example
+
+@noindent
+So, deleting a group tells @code{g77} to pretend as though the intrinsics in
+that group do not exist at all, whereas disabling it tells @code{g77} to
+recognize them as (disabled) intrinsics in intrinsic-like contexts.
+
+Hiding a group is like enabling it, but the intrinsic must be first
+named in an @code{INTRINSIC} statement to be considered a reference to the

+This might be the ``safest'' way to treat a new group of intrinsics
+when compiling old
+code, because it allows the old code to be generally written as if
+those new intrinsics never existed, but to be changed to use them

+@chapter Other Compilers
+
+An individual Fortran source file can be compiled to
+an object (@file{*.o}) file instead of to the final
+program executable.
+This allows several portions of a program to be compiled
+at different times and linked together whenever a new
+version of the program is needed.
+However, it introduces the issue of @dfn{object compatibility}
+across the various object files (and libraries, or @file{*.a}
+files) that are linked together to produce any particular
+executable file.
+
+Object compatibility is an issue when combining, in one
+program, Fortran code compiled by more than one compiler
+(or more than one configuration of a compiler).
+If the compilers
+disagree on how to transform the names of procedures, there
+will normally be errors when linking such programs.
+Worse, if the compilers agree on naming, but disagree on issues
+like how to pass parameters, return arguments, and lay out
+@code{COMMON} areas, the earliest detected errors might be the
+incorrect results produced by the program (and that assumes
+these errors are detected, which is not always the case).
+
+Normally, @code{g77} generates code that is
+object-compatible with code generated by a version of
+@code{f2c} configured (with, for example, @file{f2c.h} definitions)
+to be generally compatible with @code{g77} as built by @code{gcc}.
+(Normally, @code{f2c} will, by default, conform to the appropriate
+configuration, but it is possible that older or perhaps even newer
+versions of @code{f2c}, or versions having certain configuration changes
+to @code{f2c} internals, will produce object files that are
+incompatible with @code{g77}.)
+
+For example, a Fortran string subroutine
+argument will become two arguments on the C side: a @code{char *}
+and an @code{int} length.
+
+Much of this compatibility results from the fact that
+@code{g77} uses the same run-time library,
+@code{libf2c}, used by @code{f2c},
+though @code{g77} gives its version the name @code{libg2c}
+so as to avoid conflicts when linking,
+installing them in the same directories,
+and so on.
+
+Other compilers might or might not generate code that
+is object-compatible with @code{libg2c} and current @code{g77},
+and some might offer such compatibility only when explicitly
+selected via a command-line option to the compiler.

+
+@node Dropping f2c Compatibility
+@section Dropping @code{f2c} Compatibility
+
+Specifying @samp{-fno-f2c} allows @code{g77} to generate, in
+some cases, faster code, by not needing to allow to the possibility
+of linking with code compiled by @code{f2c}.
+
+For example, this affects how @code{REAL(KIND=1)},
+@code{COMPLEX(KIND=1)}, and @code{COMPLEX(KIND=2)} functions are called.
+With @samp{-fno-f2c}, they are
+compiled as returning the appropriate @code{gcc} type
+(@code{float}, @code{__complex__ float}, @code{__complex__ double},
+in many configurations).
+
+With @samp{-ff2c} in force, they
+are compiled differently (with perhaps slower run-time performance)
+to accommodate the restrictions inherent in @code{f2c}'s use of K&R
+C as an intermediate language---@code{REAL(KIND=1)} functions
+return C's @code{double} type, while @code{COMPLEX} functions return
+@code{void} and use an extra argument pointing to a place for the functions to
+return their values.
+
+It is possible that, in some cases, leaving @samp{-ff2c} in force
+might produce faster code than using @samp{-fno-f2c}.
+Feel free to experiment, but remember to experiment with changing the way
+@emph{entire programs and their Fortran libraries are compiled} at
+a time, since this sort of experimentation affects the interface
+of code generated for a Fortran source file---that is, it affects
+object compatibility.
+
+Note that @code{f2c} compatibility is a fairly static target to achieve,
+though not necessarily perfectly so, since, like @code{g77}, it is
+still being improved.
+However, specifying @samp{-fno-f2c} causes @code{g77}
+to generate code that will probably be incompatible with code
+generated by future versions of @code{g77} when the same option
+is in force.
+You should make sure you are always able to recompile complete
+programs from source code when upgrading to new versions of @code{g77}
+or @code{f2c}, especially when using options such as @samp{-fno-f2c}.
+
+Therefore, if you are using @code{g77} to compile libraries and other
+object files for possible future use and you don't want to require
+recompilation for future use with subsequent versions of @code{g77},
+you might want to stick with @code{f2c} compatibility for now, and
+carefully watch for any announcements about changes to the
+@code{f2c}/@code{libf2c} interface that might affect existing programs
+(thus requiring recompilation).
+
+It is probable that a future version of @code{g77} will not,
+by default, generate object files compatible with @code{f2c},
+and that version probably would no longer use @code{libf2c}.
+If you expect to depend on this compatibility in the
+long term, use the options @samp{-ff2c -ff2c-library} when compiling
+all of the applicable code.
+This should cause future versions of @code{g77} either to produce
+compatible code (at the expense of the availability of some features and
+performance), or at the very least, to produce diagnostics.
+
+(The library @code{g77} produces will no longer be named @file{libg2c}
+when it is no longer generally compatible with @file{libf2c}.
+It will likely be referred to, and, if installed as a distinct
+library, named @code{libg77}, or some other as-yet-unused name.)
+
+@node Compilers Other Than f2c
+@section Compilers Other Than @code{f2c}
+
+On systems with Fortran compilers other than @code{f2c} and @code{g77},
+code compiled by @code{g77} is not expected to work
+well with code compiled by the native compiler.
+(This is true for @code{f2c}-compiled objects as well.)
+Libraries compiled with the native compiler probably will have
+to be recompiled with @code{g77} to be used with @code{g77}-compiled code.
+
+Reasons for such incompatibilities include:
+
+@itemize @bullet
+@item
+There might be differences in the way names of Fortran procedures
+are translated for use in the system's object-file format.
+For example, the statement @samp{CALL FOO} might be compiled
+by @code{g77} to call a procedure the linker @code{ld} sees
+given the name @samp{_foo_}, while the apparently corresponding
+statement @samp{SUBROUTINE FOO} might be compiled by the
+native compiler to define the linker-visible name @samp{_foo},
+or @samp{_FOO_}, and so on.
+
+@item
+There might be subtle type mismatches which cause subroutine arguments
+and function return values to get corrupted.
+
+This is why simply getting @code{g77} to
+transform procedure names the same way a native
+compiler does is not usually a good idea---unless
+some effort has been made to ensure that, aside
+from the way the two compilers transform procedure
+names, everything else about the way they generate
+code for procedure interfaces is identical.
+
+@item
+Native compilers
+use libraries of private I/O routines which will not be available
+at link time unless you have the native compiler---and you would
+have to explicitly ask for them.
+
+For example, on the Sun you
+would have to add @samp{-L/usr/lang/SCx.x -lF77 -lV77} to the link
+command.

+A simple and foolproof way to write @code{g77}-callable C routines---e.g.@: to

+skeletons comprising just the declaration of the routine(s) and dummy

+Then run @code{f2c} on file @file{fred.f} to produce @file{fred.c}

+@code{f2c} can be used to generate suitable code for compilation with a

+The important thing about linking @code{g77}-compiled
+code with C++ is that the prototypes for the @code{g77}
+routines must specify C linkage to avoid name mangling.
+So, use an @samp{extern "C"} declaration.
+@code{f2c}'s @samp{-C++} option will take care

+@subsection Startup Code
+
+@cindex startup code
+@cindex runtime initialization
+@cindex initialization, runtime
+Unlike with some runtime systems,
+it shouldn't be necessary
+(unless there are bugs)
+to use a Fortran main program unit to ensure the
+runtime---specifically the I/O system---is initialized.
+
+However, to use the @code{g77} intrinsics @code{GETARG} and @code{IARGC},
+either the @code{main} routine from the @file{libg2c} library must be used,
+or the @code{f_setarg} routine
+(new as of @code{egcs} version 1.1 and @code{g77} version 0.5.23)
+must be called with the appropriate @code{argc} and @code{argv} arguments
+prior to the program calling @code{GETARG} or @code{IARGC}.
+
+To provide more flexibility for mixed-language programming
+involving @code{g77} while allowing for shared libraries,
+as of @code{egcs} version 1.1 and @code{g77} version 0.5.23,
+@code{g77}'s @code{main} routine in @code{libg2c}
+does the following, in order:
+
+@enumerate
+@item
+Calls @code{f_setarg}
+with the incoming @code{argc} and @code{argv} arguments,
+in the same order as for @code{main} itself.
+
+This sets up the command-line environment
+for @code{GETARG} and @code{IARGC}.
+
+@item
+Calls @code{f_setsig} (with no arguments).
+
+This sets up the signaling and exception environment.
+
+@item
+Calls @code{f_init} (with no arguments).
+
+This initializes the I/O environment,
+though that should not be necessary,
+as all I/O functions in @code{libf2c}
+are believed to call @code{f_init} automatically,
+if necessary.
+
+(A future version of @code{g77} might skip this explicit step,
+to speed up normal exit of a program.)
+
+@item
+Arranges for @code{f_exit} to be called (with no arguments)
+when the program exits.
+
+This ensures that the I/O environment is properly shut down
+before the program exits normally.
+Otherwise, output buffers might not be fully flushed,
+scratch files might not be deleted, and so on.
+
+The simple way @code{main} does this is
+to call @code{f_exit} itself after calling
+@code{MAIN__} (in the next step).
+
+However, this does not catch the cases where the program
+might call @code{exit} directly,
+instead of using the @code{EXIT} intrinsic
+(implemented as @code{exit_} in @code{libf2c}).
+
+So, @code{main} attempts to use
+the operating environment's @code{onexit} or @code{atexit}
+facility, if available,
+to cause @code{f_exit} to be called automatically
+upon any invocation of @code{exit}.
+
+@item
+Calls @code{MAIN__} (with no arguments).
+
+This starts executing the Fortran main program unit for
+the application.
+(Both @code{g77} and @code{f2c} currently compile a main
+program unit so that its global name is @code{MAIN__}.)
+
+@item
+If no @code{onexit} or @code{atexit} is provided by the system,
+calls @code{f_exit}.
+
+@item
+Calls @code{exit} with a zero argument,
+to signal a successful program termination.
+
+@item
+Returns a zero value to the caller,
+to signal a successful program termination,
+in case @code{exit} doesn't exit on the system.
+@end enumerate
+
+All of the above names are C @code{extern} names,
+i.e.@: not mangled.
+
+When using the @code{main} procedure provided by @code{g77}
+without a Fortran main program unit,
+you need to provide @code{MAIN__}
+as the entry point for your C code.
+(Make sure you link the object file that defines that
+entry point with the rest of your program.)
+
+To provide your own @code{main} procedure
+in place of @code{g77}'s,
+make sure you specify the object file defining that procedure
+@emph{before} @samp{-lg2c} on the @code{g77} command line.
+Since the @samp{-lg2c} option is implicitly provided,
+this is usually straightforward.
+(Use the @samp{--verbose} option to see how and where
+@code{g77} implicitly adds @samp{-lg2c} in a command line
+that will link the program.
+Feel free to specify @samp{-lg2c} explicitly,
+as appropriate.)
+
+However, when providing your own @code{main},
+make sure you perform the appropriate tasks in the
+appropriate order.
+For example, if your @code{main} does not call @code{f_setarg},
+make sure the rest of your application does not call
+@code{GETARG} or @code{IARGC}.
+
+And, if your @code{main} fails to ensure that @code{f_exit}
+is called upon program exit,
+some files might end up incompletely written,
+some scratch files might be left lying around,
+and some existing files being written might be left
+with old data not properly truncated at the end.
+
+Note that, generally, the @code{g77} operating environment
+does not depend on a procedure named @code{MAIN__} actually
+being called prior to any other @code{g77}-compiled code.
+That is, @code{MAIN__} does not, itself,
+set up any important operating-environment characteristics
+upon which other code might depend.
+This might change in future versions of @code{g77},
+with appropriate notification in the release notes.
+
+For more information, consult the source code for the above routines.

+@section Main Program Unit (PROGRAM)
+@cindex PROGRAM statement
+@cindex statements, PROGRAM
+
+When @code{g77} compiles a main program unit, it gives it the public
+procedure name @samp{MAIN__}.
+The @code{libg2c} library has the actual @code{main()} procedure
+as is typical of C-based environments, and
+it is this procedure that performs some initial start-up
+activity and then calls @samp{MAIN__}.
+
+Generally, @code{g77} and @code{libg2c} are designed so that you need not
+include a main program unit written in Fortran in your program---it
+can be written in C or some other language.
+Especially for I/O handling, this is the case, although @code{g77} version 0.5.16
+includes a bug fix for @code{libg2c} that solved a problem with using the
+@code{OPEN} statement as the first Fortran I/O activity in a program
+without a Fortran main program unit.
+
+However, if you don't intend to use @code{g77} (or @code{f2c}) to compile
+your main program unit---that is, if you intend to compile a @code{main()}
+procedure using some other language---you should carefully
+examine the code for @code{main()} in @code{libg2c}, found in the source
+file @file{@value{path-libf2c}/libF77/main.c}, to see what kinds of things
+might need to be done by your @code{main()} in order to provide the

+When debugging, one implication of the fact that @code{main()}, which
+is the place where the debugged program ``starts'' from the
+debugger's point of view, is in @code{libg2c} is that you won't be
+starting your Fortran program at a point you recognize as your
+Fortran code.
+
+The standard way to get around this problem is to set a break
+point (a one-time, or temporary, break point will do) at
+the entrance to @samp{MAIN__}, and then run the program.
+A convenient way to do so is to add the @code{gdb} command
+
+@example
+tbreak MAIN__
+@end example
+
+@noindent
+to the file @file{.gdbinit} in the directory in which you're debugging
+(using @code{gdb}).
+
+After doing this, the debugger will see the current execution
+point of the program as at the beginning of the main program
+unit of your program.
+
+Of course, if you really want to set a break point at some
+other place in your program and just start the program
+running, without first breaking at @samp{MAIN__},
+that should work fine.

+@cindex signature of procedures
+
+Currently, @code{g77} passes arguments via reference---specifically,
+by passing a pointer to the location in memory of a variable, array,
+array element, a temporary location that holds the result of evaluating an
+expression, or a temporary or permanent location that holds the value
+of a constant.
+
+Procedures that accept @code{CHARACTER} arguments are implemented by
+@code{g77} so that each @code{CHARACTER} argument has two actual arguments.
+
+The first argument occupies the expected position in the
+argument list and has the user-specified name.
+This argument
+is a pointer to an array of characters, passed by the caller.
+
+The second argument is appended to the end of the user-specified
+calling sequence and is named @samp{__g77_length_@var{x}}, where @var{x}
+is the user-specified name.
+This argument is of the C type @code{ftnlen}
+(see @file{@value{path-libf2c}/g2c.h.in} for information on that type) and
+is the number of characters the caller has allocated in the
+array pointed to by the first argument.
+
+A procedure will ignore the length argument if @samp{X} is not declared
+@code{CHARACTER*(*)}, because for other declarations, it knows the
+length.
+Not all callers necessarily ``know'' this, however, which
+is why they all pass the extra argument.
+
+The contents of the @code{CHARACTER} argument are specified by the
+address passed in the first argument (named after it).
+The procedure can read or write these contents as appropriate.
+
+When more than one @code{CHARACTER} argument is present in the argument
+list, the length arguments are appended in the order
+the original arguments appear.
+So @samp{CALL FOO('HI','THERE')} is implemented in
+C as @samp{foo("hi","there",2,5);}, ignoring the fact that @code{g77}
+does not provide the trailing null bytes on the constant
+strings (@code{f2c} does provide them, but they are unnecessary in
+a Fortran environment, and you should not expect them to be
+there).
+
+Note that the above information applies to @code{CHARACTER} variables and
+arrays @strong{only}.
+It does @strong{not} apply to external @code{CHARACTER}
+functions or to intrinsic @code{CHARACTER} functions.
+That is, no second length argument is passed to @samp{FOO} in this case:
+
+@example
+CHARACTER X
+EXTERNAL X
+CALL FOO(X)
+@end example
+
+@noindent
+Nor does @samp{FOO} expect such an argument in this case:
+
+@example
+SUBROUTINE FOO(X)
+CHARACTER X
+EXTERNAL X
+@end example
+
+Because of this implementation detail, if a program has a bug
+such that there is disagreement as to whether an argument is
+a procedure, and the type of the argument is @code{CHARACTER}, subtle
+symptoms might appear.

+
+For @code{CHARACTER}, @code{g77} implements a subroutine (a C function

+with two arguments prepended: @samp{__g77_result}, which the caller passes
+as a pointer to a @code{char} array expected to hold the return value,
+and @samp{__g77_length}, which the caller passes as an @code{ftnlen} value
+specifying the length of the return value as declared in the calling
+program.
+For @code{CHARACTER*(*)}, the called function uses @samp{__g77_length}
+to determine the size of the array that @samp{__g77_result} points to;
+otherwise, it ignores that argument.
+
+For @code{COMPLEX}, when @samp{-ff2c} is in
+force, @code{g77} implements
+a subroutine with one argument prepended: @samp{__g77_result}, which the
+caller passes as a pointer to a variable of the type of the function.
+The called function writes the return value into this variable instead
+of returning it as a function value.
+When @samp{-fno-f2c} is in force,
+@code{g77} implements a @code{COMPLEX} function as @code{gcc}'s
+@samp{__complex__ float} or @samp{__complex__ double} function
+(or an emulation thereof, when @samp{-femulate-complex} is in effect),
+returning the result of the function in the same way as @code{gcc} would.
+
+For @code{REAL(KIND=1)}, when @samp{-ff2c} is in force, @code{g77} implements
+a function that actually returns @code{REAL(KIND=2)} (typically

+
+Fortran permits each implementation to decide how to represent
+names as far as how they're seen in other contexts, such as debuggers
+and when interfacing to other languages, and especially as far

+
+External names---names of entities that are public, or ``accessible'',
+to all modules in a program---normally have an underscore (@samp{_})
+appended by @code{g77},
+to generate code that is compatible with @code{f2c}.
+External names include names of Fortran things like common blocks,
+external procedures (subroutines and functions, but not including
+statement functions, which are internal procedures), and entry point
+names.
+
+However, use of the @samp{-fno-underscoring} option
+disables this kind of transformation of external names (though inhibiting
+the transformation certainly improves the chances of colliding with
+incompatible externals written in other languages---but that
+might be intentional.

+When @samp{-funderscoring} is in force, any name (external or local)
+that already has at least one underscore in it is
+implemented by @code{g77} by appending two underscores.
+(This second underscore can be disabled via the
+@samp{-fno-second-underscore} option.)
+External names are changed this way for @code{f2c} compatibility.
+Local names are changed this way to avoid collisions with external names
+that are different in the source code---@code{f2c} does the same thing, but
+there's no compatibility issue there except for user expectations while
+debugging.
+
+For example:
+
+@example
+Max_Cost = 0
+@end example
+
+@cindex debugging
+@noindent
+Here, a user would, in the debugger, refer to this variable using the
+name @samp{max_cost__} (or @samp{MAX_COST__} or @samp{Max_Cost__},
+as described below).
+(We hope to improve @code{g77} in this regard in the future---don't
+write scripts depending on this behavior!
+Also, consider experimenting with the @samp{-fno-underscoring}
+option to try out debugging without having to massage names by
+hand like this.)
+
+@code{g77} provides a number of command-line options that allow the user
+to control how case mapping is handled for source files.
+The default is the traditional UNIX model for Fortran compilers---names
+are mapped to lower case.
+Other command-line options can be specified to map names to upper
+case, or to leave them exactly as written in the source file.
+
+For example:
+
+@example
+Foo = 9.436
+@end example
+
+@noindent
+Here, it is normally the case that the variable assigned will be named
+@samp{foo}.
+This would be the name to enter when using a debugger to
+access the variable.
+
+However, depending on the command-line options specified, the
+name implemented by @code{g77} might instead be @samp{FOO} or even
+@samp{Foo}, thus affecting how debugging is done.
+
+Also:
+
+@example
+Call Foo
+@end example
+
+@noindent
+This would normally call a procedure that, if it were in a separate C program,
+be defined starting with the line:
+
+@example
+void foo_()
+@end example
+
+@noindent
+However, @code{g77} command-line options could be used to change the casing
+of names, resulting in the name @samp{FOO_} or @samp{Foo_} being given to the
+procedure instead of @samp{foo_}, and the @samp{-fno-underscoring} option
+could be used to inhibit the appending of the underscore to the name.

+
+The name @code{g77} gives this array of @code{char} type is @samp{__g77_equiv_@var{x}},

+As of 0.5.20, @code{g77} defaults to handling @code{COMPLEX} types
+(and related intrinsics, constants, functions, and so on)
+in a manner that
+makes direct debugging involving these types in Fortran
+language mode difficult.
+
+Essentially, @code{g77} implements these types using an
+internal construct similar to C's @code{struct}, at least
+as seen by the @code{gcc} back end.
+
+Currently, the back end, when outputting debugging info with
+the compiled code for the assembler to digest, does not detect
+these @code{struct} types as being substitutes for Fortran
+complex.
+As a result, the Fortran language modes of debuggers such as
+@code{gdb} see these types as C @code{struct} types, which
+they might or might not support.
+
+Until this is fixed, switch to C language mode to work with

+mode afterward.

+@cindex row-major ordering
+@cindex arrays
+
+Fortran uses ``column-major ordering'' in its arrays.
+This differs from other languages, such as C, which use ``row-major ordering''.
+The difference is that, with Fortran, array elements adjacent to
+each other in memory differ in the @emph{first} subscript instead of
+the last; @samp{A(5,10,20)} immediately follows @samp{A(4,10,20)},
+whereas with row-major ordering it would follow @samp{A(5,10,19)}.
+
+This consideration
+affects not only interfacing with and debugging Fortran code,
+it can greatly affect how code is designed and written, especially
+when code speed and size is a concern.
+
+Fortran also differs from C, a popular language for interfacing and
+to support directly in debuggers, in the way arrays are treated.
+In C, arrays are single-dimensional and have interesting relationships
+to pointers, neither of which is true for Fortran.
+As a result, dealing with Fortran arrays from within
+an environment limited to C concepts can be challenging.
+
+For example, accessing the array element @samp{A(5,10,20)} is easy enough
+in Fortran (use @samp{A(5,10,20)}), but in C some difficult machinations
+are needed.
+First, C would treat the A array as a single-dimension array.
+Second, C does not understand low bounds for arrays as does Fortran.
+Third, C assumes a low bound of zero (0), while Fortran defaults to a
+low bound of one (1) and can supports an arbitrary low bound.
+Therefore, calculations must be done
+to determine what the C equivalent of @samp{A(5,10,20)} would be, and these
+calculations require knowing the dimensions of @samp{A}.
+
+For @samp{DIMENSION A(2:11,21,0:29)}, the calculation of the offset of
+@samp{A(5,10,20)} would be:
+
+@example
+  (5-2)
++ (10-1)*(11-2+1)
++ (20-0)*(11-2+1)*(21-1+1)
+= 4293
+@end example
+
+@noindent
+So the C equivalent in this case would be @samp{a[4293]}.
+
+When using a debugger directly on Fortran code, the C equivalent
+might not work, because some debuggers cannot understand the notion
+of low bounds other than zero.  However, unlike @code{f2c}, @code{g77}
+does inform the GBE that a multi-dimensional array (like @samp{A}
+in the above example) is really multi-dimensional, rather than a
+single-dimensional array, so at least the dimensionality of the array
+is preserved.
+
+Debuggers that understand Fortran should have no trouble with
+non-zero low bounds, but for non-Fortran debuggers, especially
+C debuggers, the above example might have a C equivalent of
+@samp{a[4305]}.
+This calculation is arrived at by eliminating the subtraction
+of the lower bound in the first parenthesized expression on each
+line---that is, for @samp{(5-2)} substitute @samp{(5)}, for @samp{(10-1)}
+substitute @samp{(10)}, and for @samp{(20-0)} substitute @samp{(20)}.
+Actually, the implication of
+this can be that the expression @samp{*(&a[2][1][0] + 4293)} works fine,
+but that @samp{a[20][10][5]} produces the equivalent of
+@samp{*(&a[0][0][0] + 4305)} because of the missing lower bounds.
+
+Come to think of it, perhaps
+the behavior is due to the debugger internally compensating for
+the lower bounds by offsetting the base address of @samp{a}, leaving
+@samp{&a} set lower, in this case, than @samp{&a[2][1][0]} (the address of
+its first element as identified by subscripts equal to the
+corresponding lower bounds).
+
+You know, maybe nobody really needs to use arrays.

+
+Adjustable and automatic arrays in Fortran require the implementation
+(in this
+case, the @code{g77} compiler) to ``memorize'' the expressions that
+dimension the arrays each time the procedure is invoked.
+This is so that subsequent changes to variables used in those
+expressions, made during execution of the procedure, do not
+have any effect on the dimensions of those arrays.
+
+For example:
+
+@example
+REAL ARRAY(5)
+DATA ARRAY/5*2/
+CALL X(ARRAY, 5)
+END
+SUBROUTINE X(A, N)
+DIMENSION A(N)
+N = 20
+PRINT *, N, A
+END
+@end example
+
+@noindent
+Here, the implementation should, when running the program, print something
+like:
+
+@example
+20   2.  2.  2.  2.  2.
+@end example
+
+@noindent
+Note that this shows that while the value of @samp{N} was successfully
+changed, the size of the @samp{A} array remained at 5 elements.
+
+To support this, @code{g77} generates code that executes before any user
+code (and before the internally generated computed @code{GOTO} to handle
+alternate entry points, as described below) that evaluates each
+(nonconstant) expression in the list of subscripts for an
+array, and saves the result of each such evaluation to be used when
+determining the size of the array (instead of re-evaluating the
+expressions).
+
+So, in the above example, when @samp{X} is first invoked, code is
+executed that copies the value of @samp{N} to a temporary.
+And that same temporary serves as the actual high bound for the single
+dimension of the @samp{A} array (the low bound being the constant 1).
+Since the user program cannot (legitimately) change the value
+of the temporary during execution of the procedure, the size
+of the array remains constant during each invocation.
+
+For alternate entry points, the code @code{g77} generates takes into
+account the possibility that a dummy adjustable array is not actually
+passed to the actual entry point being invoked at that time.
+In that case, the public procedure implementing the entry point
+passes to the master private procedure implementing all the
+code for the entry points a @code{NULL} pointer where a pointer to that
+adjustable array would be expected.
+The @code{g77}-generated code
+doesn't attempt to evaluate any of the expressions in the subscripts
+for an array if the pointer to that array is @code{NULL} at run time in
+such cases.
+(Don't depend on this particular implementation
+by writing code that purposely passes @code{NULL} pointers where the
+callee expects adjustable arrays, even if you know the callee
+won't reference the arrays---nor should you pass @code{NULL} pointers
+for any dummy arguments used in calculating the bounds of such
+arrays or leave undefined any values used for that purpose in
+COMMON---because the way @code{g77} implements these things might

+@cindex ENTRY statement
+@cindex statements, ENTRY
+
+The GBE does not understand the general concept of
+alternate entry points as Fortran provides via the ENTRY statement.
+@code{g77} gets around this by using an approach to compiling procedures
+having at least one @code{ENTRY} statement that is almost identical to the
+approach used by @code{f2c}.
+(An alternate approach could be used that
+would probably generate faster, but larger, code that would also
+be a bit easier to debug.)
+
+Information on how @code{g77} implements @code{ENTRY} is provided for those
+trying to debug such code.
+The choice of implementation seems
+unlikely to affect code (compiled in other languages) that interfaces
+to such code.
+
+@code{g77} compiles exactly one public procedure for the primary entry
+point of a procedure plus each @code{ENTRY} point it specifies, as usual.
+That is, in terms of the public interface, there is no difference
+between
+
+@example
+SUBROUTINE X
+END
+SUBROUTINE Y
+END
+@end example
+
+@noindent
+and:
+
+@example
+SUBROUTINE X
+ENTRY Y
+END
+@end example
+
+The difference between the above two cases lies in the code compiled
+for the @samp{X} and @samp{Y} procedures themselves, plus the fact that,
+for the second case, an extra internal procedure is compiled.
+
+For every Fortran procedure with at least one @code{ENTRY}
+statement, @code{g77} compiles an extra procedure
+named @samp{__g77_masterfun_@var{x}}, where @var{x} is
+the name of the primary entry point (which, in the above case,
+using the standard compiler options, would be @samp{x_} in C).
+
+This extra procedure is compiled as a private procedure---that is,
+a procedure not accessible by name to separately compiled modules.
+It contains all the code in the program unit, including the code
+for the primary entry point plus for every entry point.
+(The code for each public procedure is quite short, and explained later.)
+
+The extra procedure has some other interesting characteristics.
+
+The argument list for this procedure is invented by @code{g77}.
+It contains
+a single integer argument named @samp{__g77_which_entrypoint},
+passed by value (as in Fortran's @samp{%VAL()} intrinsic), specifying the
+entry point index---0 for the primary entry point, 1 for the
+first entry point (the first @code{ENTRY} statement encountered), 2 for
+the second entry point, and so on.
+
+It also contains, for functions returning @code{CHARACTER} and
+(when @samp{-ff2c} is in effect) @code{COMPLEX} functions,
+and for functions returning different types among the
+@code{ENTRY} statements (e.g. @samp{REAL FUNCTION R()}
+containing @samp{ENTRY I()}), an argument named @samp{__g77_result} that
+is expected at run time to contain a pointer to where to store
+the result of the entry point.
+For @code{CHARACTER} functions, this
+storage area is an array of the appropriate number of characters;
+for @code{COMPLEX} functions, it is the appropriate area for the return
+type; for multiple-return-type functions, it is a union of all the supported return
+types (which cannot include @code{CHARACTER}, since combining @code{CHARACTER}
+and non-@code{CHARACTER} return types via @code{ENTRY} in a single function
+is not supported by @code{g77}).
+
+For @code{CHARACTER} functions, the @samp{__g77_result} argument is followed
+by yet another argument named @samp{__g77_length} that, at run time,
+specifies the caller's expected length of the returned value.
+Note that only @code{CHARACTER*(*)} functions and entry points actually
+make use of this argument, even though it is always passed by
+all callers of public @code{CHARACTER} functions (since the caller does not
+generally know whether such a function is @code{CHARACTER*(*)} or whether
+there are any other callers that don't have that information).
+
+The rest of the argument list is the union of all the arguments
+specified for all the entry points (in their usual forms, e.g.
+@code{CHARACTER} arguments have extra length arguments, all appended at
+the end of this list).
+This is considered the ``master list'' of
+arguments.
+
+The code for this procedure has, before the code for the first
+executable statement, code much like that for the following Fortran
+statement:
+
+@smallexample
+       GOTO (100000,100001,100002), __g77_which_entrypoint
+100000 @dots{}code for primary entry point@dots{}
+100001 @dots{}code immediately following first ENTRY statement@dots{}
+100002 @dots{}code immediately following second ENTRY statement@dots{}
+@end smallexample
+
+@noindent
+(Note that invalid Fortran statement labels and variable names
+are used in the above example to highlight the fact that it
+represents code generated by the @code{g77} internals, not code to be
+written by the user.)
+
+It is this code that, when the procedure is called, picks which
+entry point to start executing.
+
+Getting back to the public procedures (@samp{x} and @samp{Y} in the original
+example), those procedures are fairly simple.
+Their interfaces
+are just like they would be if they were self-contained procedures
+(without @code{ENTRY}), of course, since that is what the callers
+expect.
+Their code consists of simply calling the private
+procedure, described above, with the appropriate extra arguments
+(the entry point index, and perhaps a pointer to a multiple-type-
+return variable, local to the public procedure, that contains
+all the supported returnable non-character types).
+For arguments
+that are not listed for a given entry point that are listed for
+other entry points, and therefore that are in the ``master list''
+for the private procedure, null pointers (in C, the @code{NULL} macro)
+are passed.
+Also, for entry points that are part of a multiple-type-
+returning function, code is compiled after the call of the private
+procedure to extract from the multi-type union the appropriate result,
+depending on the type of the entry point in question, returning
+that result to the original caller.
+
+When debugging a procedure containing alternate entry points, you
+can either set a break point on the public procedure itself (e.g.
+a break point on @samp{X} or @samp{Y}) or on the private procedure that
+contains most of the pertinent code (e.g. @samp{__g77_masterfun_@var{x}}).
+If you do the former, you should use the debugger's command to
+``step into'' the called procedure to get to the actual code; with
+the latter approach, the break point leaves you right at the
+actual code, skipping over the public entry point and its call
+to the private procedure (unless you have set a break point there
+as well, of course).
+
+Further, the list of dummy arguments that is visible when the
+private procedure is active is going to be the expanded version
+of the list for whichever particular entry point is active,
+as explained above, and the way in which return values are
+handled might well be different from how they would be handled
+for an equivalent single-entry function.

+@subsection Language Extensions
+
+@code{g77} offers several extensions to the Fortran language that @code{f2c}
+doesn't.
+
+However, @code{f2c} offers a few that @code{g77} doesn't, like
+fairly complete support for @code{INTEGER*2}.
+It is expected that @code{g77} will offer some or all of these missing
+features at some time in the future.
+(Version 0.5.18 of @code{g77} offers some rudimentary support for some
+of these features.)
+
+@node Compiler Options
+@subsection Compiler Options
+
+@code{g77} offers a whole bunch of compiler options that @code{f2c} doesn't.
+
+However, @code{f2c} offers a few that @code{g77} doesn't, like an
+option to generate code to check array subscripts at run time.
+It is expected that @code{g77} will offer some or all of these
+missing options at some time in the future.
+
+@node Compiler Speed
+@subsection Compiler Speed
+
+Saving the steps of writing and then rereading C code is a big reason
+why @code{g77} should be able to compile code much faster than using
+@code{f2c} in conjunction with the equivalent invocation of @code{gcc}.
+
+However, due to @code{g77}'s youth, lots of self-checking is still being
+performed.
+As a result, this improvement is as yet unrealized
+(though the potential seems to be there for quite a big speedup
+in the future).
+It is possible that, as of version 0.5.18, @code{g77}
+is noticeably faster compiling many Fortran source files than using
+@code{f2c} in conjunction with @code{gcc}.
+
+@node Program Speed
+@subsection Program Speed
+
+@code{g77} has the potential to better optimize code than @code{f2c},
+even when @code{gcc} is used to compile the output of @code{f2c},
+because @code{f2c} must necessarily
+translate Fortran into a somewhat lower-level language (C) that cannot
+preserve all the information that is potentially useful for optimization,
+while @code{g77} can gather, preserve, and transmit that information directly
+to the GBE.
+
+For example, @code{g77} implements @code{ASSIGN} and assigned
+@code{GOTO} using direct assignment of pointers to labels and direct
+jumps to labels, whereas @code{f2c} maps the assigned labels to
+integer values and then uses a C @code{switch} statement to encode
+the assigned @code{GOTO} statements.
+
+However, as is typical, theory and reality don't quite match, at least
+not in all cases, so it is still the case that @code{f2c} plus @code{gcc}
+can generate code that is faster than @code{g77}.
+
+Version 0.5.18 of @code{g77} offered default
+settings and options, via patches to the @code{gcc}
+back end, that allow for better program speed, though
+some of these improvements also affected the performance
+of programs translated by @code{f2c} and then compiled
+by @code{g77}'s version of @code{gcc}.
+
+Version 0.5.20 of @code{g77} offers further performance
+improvements, at least one of which (alias analysis) is
+not generally applicable to @code{f2c} (though @code{f2c}
+could presumably be changed to also take advantage of
+this new capability of the @code{gcc} back end, assuming
+this is made available in an upcoming release of @code{gcc}).
+
+@node Ease of Debugging
+@subsection Ease of Debugging
+
+Because @code{g77} compiles directly to assembler code like @code{gcc},
+instead of translating to an intermediate language (C) as does @code{f2c},
+support for debugging can be better for @code{g77} than @code{f2c}.
+
+However, although @code{g77} might be somewhat more ``native'' in terms of
+debugging support than @code{f2c} plus @code{gcc}, there still are a lot
+of things ``not quite right''.
+Many of the important ones should be resolved in the near future.
+
+For example, @code{g77} doesn't have to worry about reserved names
+like @code{f2c} does.
+Given @samp{FOR = WHILE}, @code{f2c} must necessarily
+translate this to something @emph{other} than
+@samp{for = while;}, because C reserves those words.
+
+However, @code{g77} does still uses things like an extra level of indirection
+for @code{ENTRY}-laden procedures---in this case, because the back end doesn't
+yet support multiple entry points.
+
+Another example is that, given
+
+@smallexample
+COMMON A, B
+EQUIVALENCE (B, C)
+@end smallexample
+
+@noindent
+the @code{g77} user should be able to access the variables directly, by name,
+without having to traverse C-like structures and unions, while @code{f2c}
+is unlikely to ever offer this ability (due to limitations in the
+C language).
+
+However, due to apparent bugs in the back end, @code{g77} currently doesn't
+take advantage of this facility at all---it doesn't emit any debugging
+information for @code{COMMON} and @code{EQUIVALENCE} areas,
+other than information
+on the array of @code{char} it creates (and, in the case
+of local @code{EQUIVALENCE}, names) for each such area.
+
+Yet another example is arrays.
+@code{g77} represents them to the debugger
+using the same ``dimensionality'' as in the source code, while @code{f2c}
+must necessarily convert them all to one-dimensional arrays to fit
+into the confines of the C language.
+However, the level of support
+offered by debuggers for interactive Fortran-style access to arrays
+as compiled by @code{g77} can vary widely.
+In some cases, it can actually
+be an advantage that @code{f2c} converts everything to widely supported
+C semantics.
+
+In fairness, @code{g77} could do many of the things @code{f2c} does
+to get things working at least as well as @code{f2c}---for now,
+the developers prefer making @code{g77} work the
+way they think it is supposed to, and finding help improving the
+other products (the back end of @code{gcc}; @code{gdb}; and so on)
+to get things working properly.

+That means a constant like @samp{'HELLO'} is translated to
+@samp{"hello"} in C, which further means that an extra null byte is
+present at the end of the constant.
+This null byte is superfluous.
+
+@code{g77} does not generate such null bytes.
+This represents significant
+savings of resources, such as on systems where @file{/dev/null} or
+@file{/dev/zero} represent bottlenecks in the systems' performance,
+because @code{g77} simply asks for fewer zeros from the operating
+system than @code{f2c}.

+To ensure that block data program units are linked, especially a concern
+when they are put into libraries, give each one a name (as in
+@samp{BLOCK DATA FOO}) and make sure there is an @samp{EXTERNAL FOO}
+statement in every program unit that uses any common block
+initialized by the corresponding @code{BLOCK DATA}.
+@code{g77} currently compiles a @code{BLOCK DATA} as if it were a
+@code{SUBROUTINE},
+that is, it generates an actual procedure having the appropriate name.
+The procedure does nothing but return immediately if it happens to be
+called.
+For @samp{EXTERNAL FOO}, where @samp{FOO} is not otherwise referenced in the
+same program unit, @code{g77} assumes there exists a @samp{BLOCK DATA FOO}
+in the program and ensures that by generating a
+reference to it so the linker will make sure it is present.
+(Specifically, @code{g77} outputs in the data section a static pointer to the
+external name @samp{FOO}.)
+
+The implementation @code{g77} currently uses to make this work is
+one of the few things not compatible with @code{f2c} as currently
+shipped.
+@code{f2c} currently does nothing with @samp{EXTERNAL FOO} except
+issue a warning that @samp{FOO} is not otherwise referenced,
+and, for @samp{BLOCK DATA FOO},
+@code{f2c} doesn't generate a dummy procedure with the name @samp{FOO}.
+The upshot is that you shouldn't mix @code{f2c} and @code{g77} in
+this particular case.
+If you use @code{f2c} to compile @samp{BLOCK DATA FOO},
+then any @code{g77}-compiled program unit that says @samp{EXTERNAL FOO}
+will result in an unresolved reference when linked.
+If you do the
+opposite, then @samp{FOO} might not be linked in under various
+circumstances (such as when @samp{FOO} is in a library, or you're
+using a ``clever'' linker---so clever, it produces a broken program
+with little or no warning by omitting initializations of global data
+because they are contained in unreferenced procedures).
+
+The changes you make to your code to make @code{g77} handle this situation,
+however, appear to be a widely portable way to handle it.
+That is, many systems permit it (as they should, since the
+FORTRAN 77 standard permits @samp{EXTERNAL FOO} when @samp{FOO}
+is a block data program unit), and of the ones
+that might not link @samp{BLOCK DATA FOO} under some circumstances, most of
+them appear to do so once @samp{EXTERNAL FOO} is present in the appropriate
+program units.
+
+Here is the recommended approach to modifying a program containing
+a program unit such as the following:
+
+@smallexample
+BLOCK DATA FOO
+COMMON /VARS/ X, Y, Z
+DATA X, Y, Z / 3., 4., 5. /
+END
+@end smallexample
+
+@noindent
+If the above program unit might be placed in a library module, then
+ensure that every program unit in every program that references that
+particular @code{COMMON} area uses the @code{EXTERNAL} statement
+to force the area to be initialized.
+
+For example, change a program unit that starts with
+
+@smallexample
+INTEGER FUNCTION CURX()
+COMMON /VARS/ X, Y, Z
+CURX = X
+END
+@end smallexample
+
+@noindent
+so that it uses the @code{EXTERNAL} statement, as in:
+
+@smallexample
+INTEGER FUNCTION CURX()
+COMMON /VARS/ X, Y, Z
+EXTERNAL FOO
+CURX = X
+END
+@end smallexample
+
+@noindent
+That way, @samp{CURX} is compiled by @code{g77} (and many other
+compilers) so that the linker knows it must include @samp{FOO},
+the @code{BLOCK DATA} program unit that sets the initial values
+for the variables in @samp{VAR}, in the executable program.
+
+@node Loops
+@section Loops
+@cindex DO statement
+@cindex statements, DO
+@cindex trips, number of
+@cindex number of trips
+
+The meaning of a @code{DO} loop in Fortran is precisely specified
+in the Fortran standard@dots{}and is quite different from what
+many programmers might expect.
+
+In particular, Fortran indexed @code{DO} loops are implemented as if
+the number of trips through the loop is calculated @emph{before}
+the loop is entered.
+
+The number of trips for a loop is calculated from the @var{start},
+@var{end}, and @var{increment} values specified in a statement such as:
+
+@smallexample
+DO @var{iter} = @var{start}, @var{end}, @var{increment}
+@end smallexample
+
+@noindent
+The trip count is evaluated using a fairly simple formula
+based on the three values following the @samp{=} in the
+statement, and it is that trip count that is effectively
+decremented during each iteration of the loop.
+If, at the beginning of an iteration of the loop, the
+trip count is zero or negative, the loop terminates.
+The per-loop-iteration modifications to @var{iter} are not
+related to determining whether to terminate the loop.
+
+There are two important things to remember about the trip
+count:
+
+@itemize @bullet
+@item
+It can be @emph{negative}, in which case it is
+treated as if it was zero---meaning the loop is
+not executed at all.
+
+@item
+The type used to @emph{calculate} the trip count
+is the same type as @var{iter}, but the final
+calculation, and thus the type of the trip
+count itself, always is @code{INTEGER(KIND=1)}.
+@end itemize
+
+These two items mean that there are loops that cannot
+be written in straightforward fashion using the Fortran @code{DO}.
+
+For example, on a system with the canonical 32-bit two's-complement
+implementation of @code{INTEGER(KIND=1)}, the following loop will not work:
+
+@smallexample
+DO I = -2000000000, 2000000000
+@end smallexample
+
+@noindent
+Although the @var{start} and @var{end} values are well within
+the range of @code{INTEGER(KIND=1)}, the @emph{trip count} is not.
+The expected trip count is 40000000001, which is outside
+the range of @code{INTEGER(KIND=1)} on many systems.
+
+Instead, the above loop should be constructed this way:
+
+@smallexample
+I = -2000000000
+DO
+  IF (I .GT. 2000000000) EXIT
+  @dots{}
+  I = I + 1
+END DO
+@end smallexample
+
+@noindent
+The simple @code{DO} construct and the @code{EXIT} statement
+(used to leave the innermost loop)
+are F90 features that @code{g77} supports.
+
+Some Fortran compilers have buggy implementations of @code{DO},
+in that they don't follow the standard.
+They implement @code{DO} as a straightforward translation
+to what, in C, would be a @code{for} statement.
+Instead of creating a temporary variable to hold the trip count
+as calculated at run time, these compilers
+use the iteration variable @var{iter} to control
+whether the loop continues at each iteration.
+
+The bug in such an implementation shows up when the
+trip count is within the range of the type of @var{iter},
+but the magnitude of @samp{ABS(@var{end}) + ABS(@var{incr})}
+exceeds that range.  For example:
+
+@smallexample
+DO I = 2147483600, 2147483647
+@end smallexample

+A loop started by the above statement will work as implemented
+by @code{g77}, but the use, by some compilers, of a
+more C-like implementation akin to
+
+@smallexample
+for (i = 2147483600; i <= 2147483647; ++i)
+@end smallexample
+
+@noindent
+produces a loop that does not terminate, because @samp{i}
+can never be greater than 2147483647, since incrementing it
+beyond that value overflows @samp{i}, setting it to -2147483648.
+This is a large, negative number that still is less than 2147483647.
+
+Another example of unexpected behavior of @code{DO} involves
+using a nonintegral iteration variable @var{iter}, that is,
+a @code{REAL} variable.
+Consider the following program:
+
+@smallexample
+      DATA BEGIN, END, STEP /.1, .31, .007/
+      DO 10 R = BEGIN, END, STEP
+         IF (R .GT. END) PRINT *, R, ' .GT. ', END, '!!'
+         PRINT *,R
+10    CONTINUE
+      PRINT *,'LAST = ',R
+      IF (R .LE. END) PRINT *, R, ' .LE. ', END, '!!'
+      END
+@end smallexample
+
+@noindent
+A C-like view of @code{DO} would hold that the two ``exclamatory''
+@code{PRINT} statements are never executed.
+However, this is the output of running the above program
+as compiled by @code{g77} on a GNU/Linux ix86 system:
+
+@smallexample
+ .100000001
+ .107000001
+ .114
+ .120999999
+ @dots{}
+ .289000005

+ .303000003
+LAST =   .310000002
+ .310000002 .LE.   .310000002!!
+@end smallexample
+
+Note that one of the two checks in the program turned up
+an apparent violation of the programmer's expectation---yet,
+the loop is correctly implemented by @code{g77}, in that
+it has 30 iterations.
+This trip count of 30 is correct when evaluated using
+the floating-point representations for the @var{begin},
+@var{end}, and @var{incr} values (.1, .31, .007) on GNU/Linux
+ix86 are used.
+On other systems, an apparently more accurate trip count
+of 31 might result, but, nevertheless, @code{g77} is
+faithfully following the Fortran standard, and the result
+is not what the author of the sample program above
+apparently expected.
+(Such other systems might, for different values in the @code{DATA}
+statement, violate the other programmer's expectation,
+for example.)
+
+Due to this combination of imprecise representation
+of floating-point values and the often-misunderstood
+interpretation of @code{DO} by standard-conforming
+compilers such as @code{g77}, use of @code{DO} loops
+with @code{REAL} iteration

+@cindex implicit typing
+
+A fruitful source of bugs in Fortran source code is use, or
+mis-use, of Fortran's implicit-typing feature, whereby the
+type of a variable, array, or function is determined by the
+first character of its name.
+
+Simple cases of this include statements like @samp{LOGX=9.227},
+without a statement such as @samp{REAL LOGX}.
+In this case, @samp{LOGX} is implicitly given @code{INTEGER(KIND=1)}
+type, with the result of the assignment being that it is given
+the value @samp{9}.
+
+More involved cases include a function that is defined starting
+with a statement like @samp{DOUBLE PRECISION FUNCTION IPS(@dots{})}.
+Any caller of this function that does not also declare @samp{IPS}
+as type @code{DOUBLE PRECISION} (or, in GNU Fortran, @code{REAL(KIND=2)})
+is likely to assume it returns
+@code{INTEGER}, or some other type, leading to invalid results
+or even program crashes.
+
+The @samp{-Wimplicit} option might catch failures to
+properly specify the types of
+variables, arrays, and functions in the code.
+
+However, in code that makes heavy use of Fortran's
+implicit-typing facility, this option might produce so
+many warnings about cases that are working, it would be
+hard to find the one or two that represent bugs.
+This is why so many experienced Fortran programmers strongly
+recommend widespread use of the @code{IMPLICIT NONE} statement,
+despite it not being standard FORTRAN 77, to completely turn
+off implicit typing.
+(@code{g77} supports @code{IMPLICIT NONE}, as do almost all
+FORTRAN 77 compilers.)
+
+Note that @samp{-Wimplicit} catches only implicit typing of
+@emph{names}.
+It does not catch implicit typing of expressions such
+as @samp{X**(2/3)}.
+Such expressions can be buggy as well---in fact, @samp{X**(2/3)}
+is equivalent to @samp{X**0}, due to the way Fortran expressions
+are given types and then evaluated.
+(In this particular case, the programmer probably wanted
+@samp{X**(2./3.)}.)

+@node Variables Assumed To Be Zero
+@subsection Variables Assumed To Be Zero
+@cindex zero-initialized variables
+@cindex variables assumed to be zero
+@cindex uninitialized variables
+
+Many Fortran programs were developed on systems that provided
+automatic initialization of all, or some, variables and arrays
+to zero.
+As a result, many of these programs depend, sometimes
+inadvertently, on this behavior, though to do so violates
+the Fortran standards.
+
+You can ask @code{g77} for this behavior by specifying the
+@samp{-finit-local-zero} option when compiling Fortran code.
+(You might want to specify @samp{-fno-automatic} as well,
+to avoid code-size inflation for non-optimized compilations.)
+
+Note that a program that works better when compiled with the
+@samp{-finit-local-zero} option
+is almost certainly depending on a particular system's,
+or compiler's, tendency to initialize some variables to zero.
+It might be worthwhile finding such cases and fixing them,
+using techniques such as compiling with the @samp{-O -Wuninitialized}

+
+@node Variables Assumed To Be Saved
+@subsection Variables Assumed To Be Saved
+@cindex variables retaining values across calls
+@cindex saved variables
+@cindex static variables
+
+Many Fortran programs were developed on systems that
+saved the values of all, or some, variables and arrays
+across procedure calls.
+As a result, many of these programs depend, sometimes
+inadvertently, on being able to assign a value to a
+variable, perform a @code{RETURN} to a calling procedure,
+and, upon subsequent invocation, reference the previously
+assigned variable to obtain the value.
+
+They expect this despite not using the @code{SAVE} statement
+to specify that the value in a variable is expected to survive
+procedure returns and calls.
+Depending on variables and arrays to retain values across
+procedure calls without using @code{SAVE} to require it violates
+the Fortran standards.
+
+You can ask @code{g77} to assume @code{SAVE} is specified for all
+relevant (local) variables and arrays by using the
+@samp{-fno-automatic} option.
+
+Note that a program that works better when compiled with the
+@samp{-fno-automatic} option
+is almost certainly depending on not having to use
+the @code{SAVE} statement as required by the Fortran standard.
+It might be worthwhile finding such cases and fixing them,
+using techniques such as compiling with the @samp{-O -Wuninitialized}
+options using @code{g77}.
+
+@node Unwanted Variables
+@subsection Unwanted Variables
+
+The @samp{-Wunused} option can find bugs involving
+implicit typing, sometimes
+more easily than using @samp{-Wimplicit} in code that makes
+heavy use of implicit typing.
+An unused variable or array might indicate that the
+spelling for its declaration is different from that of
+its intended uses.
+
+Other than cases involving typos, unused variables rarely
+indicate actual bugs in a program.
+However, investigating such cases thoroughly has, on occasion,
+led to the discovery of code that had not been completely
+written---where the programmer wrote declarations as needed
+for the whole algorithm, wrote some or even most of the code
+for that algorithm, then got distracted and forgot that the
+job was not complete.
+
+@node Unused Arguments

+As with unused variables, It is possible that unused arguments
+to a procedure might indicate a bug.

+Note that @samp{-W} also enables warnings regarding overflow
+of floating-point constants under certain circumstances.
+
+@node Surprising Interpretations of Code
+@subsection Surprising Interpretations of Code
+
+The @samp{-Wsurprising} option can help find bugs involving

+are handled.
+Cases found by this option might indicate a difference of
+interpretation between the author of the code involved, and
+a standard-conforming compiler such as @code{g77}.
+Such a difference might produce actual bugs.
+
+In any case, changing the code to explicitly do what the
+programmer might have expected it to do, so @code{g77} and
+other compilers are more likely to follow the programmer's
+expectations, might be worthwhile, especially if such changes

+The @samp{-falias-check}, @samp{-fargument-alias},

+and @samp{-fno-argument-noalias-global} options,
+introduced in version 0.5.20 and
+@code{g77}'s version 2.7.2.2.f.2 of @code{gcc},
+were withdrawn as of @code{g77} version 0.5.23
+due to their not being supported by @code{gcc} version 2.8.
+
+These options, which control the assumptions regarding aliasing
+(overlapping) of writes and reads to main memory (core) made
+by the @code{gcc} back end,
+might well be added back (in some form) in a future version
+of @code{gcc}.
+
+However, these options @emph{are} supported by @code{egcs}.
+
+The information below still is useful, but applies to
+only those versions of @code{g77} that support the
+alias analysis implied by support for these options.
+
+These options are effective only when compiling with @samp{-O}
+(specifying any level other than @samp{-O0})
+or with @samp{-falias-check}.
+
+The default for Fortran code is @samp{-fargument-noalias-global}.
+(The default for C code and code written in other C-based languages
+is @samp{-fargument-alias}.
+These defaults apply regardless of whether you use @code{g77} or
+@code{gcc} to compile your code.)
+
+Note that, on some systems, compiling with @samp{-fforce-addr} in
+effect can produce more optimal code when the default aliasing
+options are in effect (and when optimization is enabled).
+
+If your program is not working when compiled with optimization,
+it is possible it is violating the Fortran standards (77 and 90)
+by relying on the ability to ``safely'' modify variables and
+arrays that are aliased, via procedure calls, to other variables
+and arrays, without using @code{EQUIVALENCE} to explicitly
+set up this kind of aliasing.
+
+(The FORTRAN 77 standard's prohibition of this sort of
+overlap, generally referred to therein as ``storage
+assocation'', appears in Sections 15.9.3.6.
+This prohibition allows implementations, such as @code{g77},
+to, for example, implement the passing of procedures and
+even values in @code{COMMON} via copy operations into local,
+perhaps more efficiently accessed temporaries at entry to a
+procedure, and, where appropriate, via copy operations back
+out to their original locations in memory at exit from that
+procedure, without having to take into consideration the
+order in which the local copies are updated by the code,
+among other things.)
+
+To test this hypothesis, try compiling your program with
+the @samp{-fargument-alias} option, which causes the
+compiler to revert to assumptions essentially the same as
+made by versions of @code{g77} prior to 0.5.20.
+
+If the program works using this option, that strongly suggests
+that the bug is in your program.
+Finding and fixing the bug(s) should result in a program that
+is more standard-conforming and that can be compiled by @code{g77}
+in a way that results in a faster executable.
+
+(You might want to try compiling with @samp{-fargument-noalias},
+a kind of half-way point, to see if the problem is limited to
+aliasing between dummy arguments and @code{COMMON} variables---this
+option assumes that such aliasing is not done, while still allowing
+aliasing among dummy arguments.)
+
+An example of aliasing that is invalid according to the standards
+is shown in the following program, which might @emph{not} produce
+the expected results when executed:
+
+@smallexample
+I = 1
+CALL FOO(I, I)
+PRINT *, I
+END
+
+SUBROUTINE FOO(J, K)
+J = J + K
+K = J * K
+PRINT *, J, K
+END
+@end smallexample
+
+The above program attempts to use the temporary aliasing of the
+@samp{J} and @samp{K} arguments in @samp{FOO} to effect a
+pathological behavior---the simultaneous changing of the values
+of @emph{both} @samp{J} and @samp{K} when either one of them
+is written.
+
+The programmer likely expects the program to print these values:
+
+@example
+2  4
+4
+@end example
+
+However, since the program is not standard-conforming, an
+implementation's behavior when running it is undefined, because
+subroutine @samp{FOO} modifies at least one of the arguments,
+and they are aliased with each other.
+(Even if one of the assignment statements was deleted, the
+program would still violate these rules.
+This kind of on-the-fly aliasing is permitted by the standard
+only when none of the aliased items are defined, or written,
+while the aliasing is in effect.)
+
+As a practical example, an optimizing compiler might schedule
+the @samp{J =} part of the second line of @samp{FOO} @emph{after}
+the reading of @samp{J} and @samp{K} for the @samp{J * K} expression,
+resulting in the following output:
+
+@example
+2  2
+2
+@end example
+
+Essentially, compilers are promised (by the standard and, therefore,
+by programmers who write code they claim to be standard-conforming)
+that if they cannot detect aliasing via static analysis of a single
+program unit's @code{EQUIVALENCE} and @code{COMMON} statements, no
+such aliasing exists.
+In such cases, compilers are free to assume that an assignment to
+one variable will not change the value of another variable, allowing
+it to avoid generating code to re-read the value of the other
+variable, to re-schedule reads and writes, and so on, to produce
+a faster executable.
+
+The same promise holds true for arrays (as seen by the called
+procedure)---an element of one dummy array cannot be aliased
+with, or overlap, any element of another dummy array or be
+in a @code{COMMON} area known to the procedure.
+
+(These restrictions apply only when the procedure defines, or
+writes to, one of the aliased variables or arrays.)
+
+Unfortunately, there is no way to find @emph{all} possible cases of
+violations of the prohibitions against aliasing in Fortran code.
+Static analysis is certainly imperfect, as is run-time analysis,
+since neither can catch all violations.
+(Static analysis can catch all likely violations, and some that
+might never actually happen, while run-time analysis can catch
+only those violations that actually happen during a particular run.
+Neither approach can cope with programs mixing Fortran code with
+routines written in other languages, however.)
+
+Currently, @code{g77} provides neither static nor run-time facilities
+to detect any cases of this problem, although other products might.
+Run-time facilities are more likely to be offered by future
+versions of @code{g77}, though patches improving @code{g77} so that
+it provides either form of detection are welcome.

+
+The effect of this is that all non-automatic variables and arrays

+@cindex Pentium optimizations
+@cindex optimizations, Pentium
+
+On some systems, such as those with Pentium Pro CPUs, programs
+that make heavy use of @code{REAL(KIND=2)} (@code{DOUBLE PRECISION})
+might run much slower
+than possible due to the compiler not aligning these 64-bit
+values to 64-bit boundaries in memory.
+(The effect also is present, though
+to a lesser extent, on the 586 (Pentium) architecture.)
+
+The Intel x86 architecture generally ensures that these programs will
+work on all its implementations,
+but particular implementations (such as Pentium Pro)
+perform better with more strict alignment.
+(Such behavior isn't unique to the Intel x86 architecture.)
+Other architectures might @emph{demand} 64-bit alignment
+of 64-bit data.
+
+There are a variety of approaches to use to address this problem:
+
+@itemize @bullet
+@item
+@cindex COMMON, layout
+@cindex layout of common blocks
+Order your @code{COMMON} and @code{EQUIVALENCE} areas such
+that the variables and arrays with the widest alignment
+guidelines come first.
+
+For example, on most systems, this would mean placing
+@code{COMPLEX(KIND=2)}, @code{REAL(KIND=2)}, and
+@code{INTEGER(KIND=2)} entities first, followed by @code{REAL(KIND=1)},
+@code{INTEGER(KIND=1)}, and @code{LOGICAL(KIND=1)} entities, then
+@code{INTEGER(KIND=6)} entities, and finally @code{CHARACTER}
+and @code{INTEGER(KIND=3)} entities.
+
+The reason to use such placement is it makes it more likely
+that your data will be aligned properly, without requiring
+you to do detailed analysis of each aggregate (@code{COMMON}
+and @code{EQUIVALENCE}) area.
+
+Specifically, on systems where the above guidelines are
+appropriate, placing @code{CHARACTER} entities before
+@code{REAL(KIND=2)} entities can work just as well,
+but only if the number of bytes occupied by the @code{CHARACTER}
+entities is divisible by the recommended alignment for
+@code{REAL(KIND=2)}.
+
+By ordering the placement of entities in aggregate
+areas according to the simple guidelines above, you
+avoid having to carefully count the number of bytes
+occupied by each entity to determine whether the
+actual alignment of each subsequent entity meets the
+alignment guidelines for the type of that entity.
+ 
+If you don't ensure correct alignment of @code{COMMON} elements, the
+compiler may be forced by some systems to violate the Fortran semantics by
+adding padding to get @code{DOUBLE PRECISION} data properly aligned.
+If the unfortunate practice is employed of overlaying different types of
+data in the @code{COMMON} block, the different variants
+of this block may become misaligned with respect to each other.
+Even if your platform doesn't require strict alignment,
+@code{COMMON} should be laid out as above for portability.
+(Unfortunately the FORTRAN 77 standard didn't anticipate this
+possible requirement, which is compiler-independent on a given platform.)
+
+@item
+@cindex -malign-double option
+@cindex options, -malign-double
+Use the (x86-specific) @samp{-malign-double} option when compiling
+programs for the Pentium and Pentium Pro architectures (called 586
+and 686 in the @code{gcc} configuration subsystem).
+The warning about this in the @code{gcc} manual isn't
+generally relevant to Fortran,
+but using it will force @code{COMMON} to be padded if necessary to align
+@code{DOUBLE PRECISION} data.
+
+When @code{DOUBLE PRECISION} data is forcibly aligned
+in @code{COMMON} by @code{g77} due to specifying @samp{-malign-double},
+@code{g77} issues a warning about the need to
+insert padding.
+
+In this case, each and every program unit that uses
+the same @code{COMMON} area
+must specify the same layout of variables and their types
+for that area
+and be compiled with @samp{-malign-double} as well.
+@code{g77} will issue warnings in each case,
+but as long as every program unit using that area
+is compiled with the same warnings,
+the resulting object files should work when linked together
+unless the program makes additional assumptions about
+@code{COMMON} area layouts that are outside the scope
+of the FORTRAN 77 standard,
+or uses @code{EQUIVALENCE} or different layouts
+in ways that assume no padding is ever inserted by the compiler.
+
+@emph{Note:} @samp{-malign-double} applies only to
+statically-allocated data.
+Double-precision data on the stack can still
+cause problems due to misalignment.
+@xref{Aligned Data}.
+
+@item
+Ensure that @file{crt0.o} or @file{crt1.o}
+on your system guarantees a 64-bit
+aligned stack for @code{main()}.
+The recent one from GNU (@code{glibc2}) will do this on x86 systems,
+but we don't know of any other x86 setups where it will be right.
+Read your system's documentation to determine if
+it is appropriate to upgrade to a more recent version
+to obtain the optimal alignment.

+Progress is being made on making this work
+``out of the box'' on future versions of @code{g77},

+@node Prefer Automatic Uninitialized Variables
+@subsection Prefer Automatic Uninitialized Variables
+
+If you're using @samp{-fno-automatic} already, you probably
+should change your code to allow compilation with @samp{-fautomatic}
+(the default), to allow the program to run faster.
+
+Similarly, you should be able to use @samp{-fno-init-local-zero}
+(the default) instead of @samp{-finit-local-zero}.
+This is because it is rare that every variable affected by these
+options in a given program actually needs to
+be so affected.
+
+For example, @samp{-fno-automatic}, which effectively @code{SAVE}s
+every local non-automatic variable and array, affects even things like
+@code{DO} iteration
+variables, which rarely need to be @code{SAVE}d, and this often reduces
+run-time performances.
+Similarly, @samp{-fno-init-local-zero} forces such
+variables to be initialized to zero---when @code{SAVE}d (such as when
+@samp{-fno-automatic}), this by itself generally affects only
+startup time for a program, but when not @code{SAVE}d,
+it can slow down the procedure every time it is called.

+@cindex hardware errors
+
+A whole variety of strange behaviors can occur when the
+software, or the way you are using the software,
+stresses the hardware in a way that triggers hardware bugs.
+This might seem hard to believe, but it happens frequently
+enough that there exist documents explaining in detail
+what the various causes of the problems are, what
+typical symptoms look like, and so on.
+
+Generally these problems are referred to in this document
+as ``signal 11'' crashes, because the Linux kernel, running
+on the most popular hardware (the Intel x86 line), often
+stresses the hardware more than other popular operating
+systems.
+When hardware problems do occur under GNU/Linux on x86
+systems, these often manifest themselves as ``signal 11''
+problems, as illustrated by the following diagnostic:
+
+@smallexample
+sh# @kbd{g77 myprog.f}
+gcc: Internal compiler error: program f771 got fatal signal 11
+sh#
+@end smallexample
+
+It is @emph{very} important to remember that the above
+message is @emph{not} the only one that indicates a
+hardware problem, nor does it always indicate a hardware
+problem.
+
+In particular, on systems other than those running the Linux
+kernel, the message might appear somewhat or very different,
+as it will if the error manifests itself while running a
+program other than the @code{g77} compiler.
+For example,
+it will appear somewhat different when running your program,
+when running Emacs, and so on.
+
+How to cope with such problems is well beyond the scope
+of this manual.
+
+However, users of Linux-based systems (such as GNU/Linux)
+should review @uref{http://www.bitwizard.nl/sig11}, a source
+of detailed information on diagnosing hardware problems,
+by recognizing their common symptoms.
+
+Users of other operating systems and hardware might
+find this reference useful as well.

+@subsection NeXTStep Problems
+@cindex NeXTStep problems
+@cindex bus error
+@cindex segmentation violation
+Developers of Fortran code on NeXTStep (all architectures) have to
+watch out for the following problem when writing programs with
+large, statically allocated (i.e. non-stack based) data structures
+(common blocks, saved arrays).
+
+Due to the way the native loader (@file{/bin/ld}) lays out
+data structures in virtual memory, it is very easy to create an
+executable wherein the @samp{__DATA} segment overlaps (has addresses in
+common) with the @samp{UNIX STACK} segment.
+
+This leads to all sorts of trouble, from the executable simply not
+executing, to bus errors.
+The NeXTStep command line tool @code{ebadexec} points to
+the problem as follows:
+
+@smallexample
+% @kbd{/bin/ebadexec a.out}
+/bin/ebadexec: __LINKEDIT segment (truncated address = 0x3de000
+rounded size = 0x2a000) of executable file: a.out overlaps with UNIX
+STACK segment (truncated address = 0x400000 rounded size =
+0x3c00000) of executable file: a.out
+@end smallexample
+
+(In the above case, it is the @samp{__LINKEDIT} segment that overlaps the
+stack segment.)
+
+This can be cured by assigning the @samp{__DATA} segment
+(virtual) addresses beyond the stack segment.
+A conservative
+estimate for this is from address 6000000 (hexadecimal) onwards---this
+has always worked for me [Toon Moene]:
+
+@smallexample
+% @kbd{g77 -segaddr __DATA 6000000 test.f}
+% @kbd{ebadexec a.out}
+ebadexec: file: a.out appears to be executable
+%
+@end smallexample
+
+Browsing through @file{@value{path-g77}/Makefile.in},
+you will find that the @code{f771} program itself also has to be
+linked with these flags---it has large statically allocated
+data structures.
+(Version 0.5.18 reduces this somewhat, but probably
+not enough.)

+@node Stack Overflow
+@subsection Stack Overflow
+@cindex stack overflow
+@cindex segmentation violation
+@code{g77} code might fail at runtime (probably with a ``segmentation
+violation'') due to overflowing the stack.
+This happens most often on systems with an environment
+that provides substantially more heap space (for use
+when arbitrarily allocating and freeing memory) than stack
+space.
+
+Often this can be cured by
+increasing or removing your shell's limit on stack usage, typically
+using @kbd{limit stacksize} (in @code{csh} and derivatives) or
+@kbd{ulimit -s} (in @code{sh} and derivatives).
+
+Increasing the allowed stack size might, however, require
+changing some operating system or system configuration parameters.
+
+You might be able to work around the problem by compiling with the
+@samp{-fno-automatic} option to reduce stack usage, probably at the
+expense of speed.
+
+@xref{Maximum Stackable Size}, for information on patching
+@code{g77} to use different criteria for placing local
+non-automatic variables and arrays on the stack.
+
+@cindex automatic arrays
+@cindex arrays, automatic
+However, if your program uses large automatic arrays
+(for example, has declarations like @samp{REAL A(N)} where
+@samp{A} is a local array and @samp{N} is a dummy or
+@code{COMMON} variable that can have a large value),
+neither use of @samp{-fno-automatic},
+nor changing the cut-off point for @code{g77} for using the stack,
+will solve the problem by changing the placement of these
+large arrays, as they are @emph{necessarily} automatic.
+
+@code{g77} currently provides no means to specify that
+automatic arrays are to be allocated on the heap instead
+of the stack.
+So, other than increasing the stack size, your best bet is to
+change your source code to avoid large automatic arrays.
+Methods for doing this currently are outside the scope of
+this document.
+
+(@emph{Note:} If your system puts stack and heap space in the
+same memory area, such that they are effectively combined, then
+a stack overflow probably indicates a program that is either
+simply too large for the system, or buggy.)

+@cindex @samp{test} programs
+@cindex programs named @samp{test}
+It is occasionally reported that a ``simple'' program,
+such as a ``Hello, World!'' program, does nothing when
+it is run, even though the compiler reported no errors,
+despite the program containing nothing other than a
+simple @code{PRINT} statement.
+
+This most often happens because the program has been
+compiled and linked on a UNIX system and named @samp{test},
+though other names can lead to similarly unexpected
+run-time behavior on various systems.
+
+Essentially this problem boils down to giving
+your program a name that is already known to
+the shell you are using to identify some other program,
+which the shell continues to execute instead of your
+program when you invoke it via, for example:
+
+@smallexample
+sh# @kbd{test}
+sh#
+@end smallexample
+
+Under UNIX and many other system, a simple command name
+invokes a searching mechanism that might well not choose
+the program located in the current working directory if
+there is another alternative (such as the @code{test}
+command commonly installed on UNIX systems).
+
+The reliable way to invoke a program you just linked in
+the current directory under UNIX is to specify it using
+an explicit pathname, as in:
+
+@smallexample
+sh# @kbd{./test}
+ Hello, World!
+sh#
+@end smallexample
+
+Users who encounter this problem should take the time to
+read up on how their shell searches for commands, how to
+set their search path, and so on.
+The relevant UNIX commands to learn about include
+@code{man}, @code{info} (on GNU systems), @code{setenv} (or

+@node Strange Behavior at Run Time
+@subsection Strange Behavior at Run Time
+@cindex segmentation violation
+@cindex bus error
+@cindex overwritten data
+@cindex data, overwritten
+@code{g77} code might fail at runtime with ``segmentation violation'',
+``bus error'', or even something as subtle as a procedure call
+overwriting a variable or array element that it is not supposed
+to touch.
+
+These can be symptoms of a wide variety of actual bugs that
+occurred earlier during the program's run, but manifested
+themselves as @emph{visible} problems some time later.
+
+Overflowing the bounds of an array---usually by writing beyond
+the end of it---is one of two kinds of bug that often occurs
+in Fortran code.
+
+The other kind of bug is a mismatch between the actual arguments
+passed to a procedure and the dummy arguments as declared by that
+procedure.
+
+Both of these kinds of bugs, and some others as well, can be
+difficult to track down, because the bug can change its behavior,
+or even appear to not occur, when using a debugger.
+
+That is, these bugs can be quite sensitive to data, including
+data representing the placement of other data in memory (that is,
+pointers, such as the placement of stack frames in memory).
+
+Plans call for improving @code{g77} so that it can offer the
+ability to catch and report some of these problems at compile, link, or
+run time, such as by generating code to detect references to
+beyond the bounds of an array, or checking for agreement between
+calling and called procedures.
+
+In the meantime, finding and fixing the programming
+bugs that lead to these behaviors is, ultimately, the user's
+responsibility, as difficult as that task can sometimes be.

+@node Floating-point Errors
+@subsection Floating-point Errors
+@cindex floating-point errors
+@cindex rounding errors
+@cindex inconsistent floating-point results
+@cindex results, inconsistent
+Some programs appear to produce inconsistent floating-point
+results compiled by @code{g77} versus by other compilers.
+
+Often the reason for this behavior is the fact that floating-point
+values are represented on almost all Fortran systems by
+@emph{approximations}, and these approximations are inexact
+even for apparently simple values like 0.1, 0.2, 0.3, 0.4, 0.6,
+0.7, 0.8, 0.9, 1.1, and so on.
+Most Fortran systems, including all current ports of @code{g77},
+use binary arithmetic to represent these approximations.
+
+Therefore, the exact value of any floating-point approximation
+as manipulated by @code{g77}-compiled code is representable by
+adding some combination of the values 1.0, 0.5, 0.25, 0.125, and
+so on (just keep dividing by two) through the precision of the
+fraction (typically around 23 bits for @code{REAL(KIND=1)}, 52 for
+@code{REAL(KIND=2)}), then multiplying the sum by a integral
+power of two (in Fortran, by @samp{2**N}) that typically is between
+-127 and +128 for @code{REAL(KIND=1)} and -1023 and +1024 for
+@code{REAL(KIND=2)}, then multiplying by -1 if the number
+is negative.
+
+So, a value like 0.2 is exactly represented in decimal---since
+it is a fraction, @samp{2/10}, with a denominator that is compatible
+with the base of the number system (base 10).
+However, @samp{2/10} cannot be represented by any finite number
+of sums of any of 1.0, 0.5, 0.25, and so on, so 0.2 cannot
+be exactly represented in binary notation.
+
+(On the other hand, decimal notation can represent any binary
+number in a finite number of digits.
+Decimal notation cannot do so with ternary, or base-3,
+notation, which would represent floating-point numbers as
+sums of any of @samp{1/1}, @samp{1/3}, @samp{1/9}, and so on.
+After all, no finite number of decimal digits can exactly
+represent @samp{1/3}.
+Fortunately, few systems use ternary notation.)
+
+Moreover, differences in the way run-time I/O libraries convert
+between these approximations and the decimal representation often
+used by programmers and the programs they write can result in
+apparent differences between results that do not actually exist,
+or exist to such a small degree that they usually are not worth
+worrying about.
+
+For example, consider the following program:
+
+@smallexample
+PRINT *, 0.2
+END
+@end smallexample
+
+When compiled by @code{g77}, the above program might output
+@samp{0.20000003}, while another compiler might produce a
+executable that outputs @samp{0.2}.
+
+This particular difference is due to the fact that, currently,
+conversion of floating-point values by the @code{libg2c} library,
+used by @code{g77}, handles only double-precision values.
+
+Since @samp{0.2} in the program is a single-precision value, it
+is converted to double precision (still in binary notation)
+before being converted back to decimal.
+The conversion to binary appends _binary_ zero digits to the
+original value---which, again, is an inexact approximation of
+0.2---resulting in an approximation that is much less exact
+than is connoted by the use of double precision.
+
+(The appending of binary zero digits has essentially the same
+effect as taking a particular decimal approximation of
+@samp{1/3}, such as @samp{0.3333333}, and appending decimal
+zeros to it, producing @samp{0.33333330000000000}.
+Treating the resulting decimal approximation as if it really
+had 18 or so digits of valid precision would make it seem
+a very poor approximation of @samp{1/3}.)
+
+As a result of converting the single-precision approximation
+to double precision by appending binary zeros, the conversion
+of the resulting double-precision
+value to decimal produces what looks like an incorrect
+result, when in fact the result is @emph{inexact}, and
+is probably no less inaccurate or imprecise an approximation
+of 0.2 than is produced by other compilers that happen to output
+the converted value as ``exactly'' @samp{0.2}.
+(Some compilers behave in a way that can make them appear
+to retain more accuracy across a conversion of a single-precision
+constant to double precision.
+@xref{Context-Sensitive Constants}, to see why
+this practice is illusory and even dangerous.)
+
+Note that a more exact approximation of the constant is
+computed when the program is changed to specify a
+double-precision constant:
+
+@smallexample
+PRINT *, 0.2D0
+END
+@end smallexample
+
+Future versions of @code{g77} and/or @code{libg2c} might convert
+single-precision values directly to decimal,
+instead of converting them to double precision first.
+This would tend to result in output that is more consistent
+with that produced by some other Fortran implementations.

+@node Better Source Model
+@subsection Better Source Model
+
+@code{g77} needs to provide, as the default source-line model,
+a ``pure visual'' mode, where
+the interpretation of a source program in this mode can be accurately
+determined by a user looking at a traditionally displayed rendition
+of the program (assuming the user knows whether the program is fixed
+or free form).
+
+The design should assume the user cannot tell tabs from spaces
+and cannot see trailing spaces on lines, but has canonical tab stops
+and, for fixed-form source, has the ability to always know exactly
+where column 72 is (since the Fortran standard itself requires
+this for fixed-form source).
+
+This would change the default treatment of fixed-form source
+to not treat lines with tabs as if they were infinitely long---instead,
+they would end at column 72 just as if the tabs were replaced
+by spaces in the canonical way.
+
+As part of this, provide common alternate models (Digital, @code{f2c},
+and so on) via command-line options.
+This includes allowing arbitrarily long
+lines for free-form source as well as fixed-form source and providing
+various limits and diagnostics as appropriate.
+
+@cindex sequence numbers
+@cindex columns 73 through 80
+Also, @code{g77} should offer, perhaps even default to, warnings
+when characters beyond the last valid column are anything other
+than spaces.
+This would mean code with ``sequence numbers'' in columns 73 through 80
+would be rejected, and there's a lot of that kind of code around,
+but one of the most frequent bugs encountered by new users is
+accidentally writing fixed-form source code into and beyond
+column 73.
+So, maybe the users of old code would be able to more easily handle
+having to specify, say, a @code{-Wno-col73to80} option.
+
+@node Fortran 90 Support
+@subsection Fortran 90 Support
+@cindex Fortran 90 support
+@cindex support, Fortran 90
+
+@code{g77} does not support many of the features that
+distinguish Fortran 90 (and, now, Fortran 95) from
+ANSI FORTRAN 77.
+
+Some Fortran 90 features are supported, because they
+make sense to offer even to die-hard users of F77.
+For example, many of them codify various ways F77 has
+been extended to meet users' needs during its tenure,
+so @code{g77} might as well offer them as the primary
+way to meet those same needs, even if it offers compatibility
+with one or more of the ways those needs were met
+by other F77 compilers in the industry.
+
+Still, many important F90 features are not supported,
+because no attempt has been made to research each and
+every feature and assess its viability in @code{g77}.
+In the meantime, users who need those features must
+use Fortran 90 compilers anyway, and the best approach
+to adding some F90 features to GNU Fortran might well be
+to fund a comprehensive project to create GNU Fortran 95.
+
+@node Intrinsics in PARAMETER Statements
+@subsection Intrinsics in @code{PARAMETER} Statements
+@cindex PARAMETER statement
+@cindex statements, PARAMETER
+
+@code{g77} doesn't allow intrinsics in @code{PARAMETER} statements.
+This feature is considered to be absolutely vital, even though it
+is not standard-conforming, and is scheduled for version 0.6.
+
+Related to this, @code{g77} doesn't allow non-integral
+exponentiation in @code{PARAMETER} statements, such as
+@samp{PARAMETER (R=2**.25)}.
+It is unlikely @code{g77} will ever support this feature,
+as doing it properly requires complete emulation of
+a target computer's floating-point facilities when
+building @code{g77} as a cross-compiler.
+But, if the @code{gcc} back end is enhanced to provide
+such a facility, @code{g77} will likely use that facility
+in implementing this feature soon afterwards.
+
+@node SELECT CASE on CHARACTER Type

+
+Some compilers, such as @code{f2c}, have an option (@samp{-r8} or
+similar) that provides automatic treatment of @code{REAL}
+entities such that they have twice the storage size, and
+a corresponding increase in the range and precision, of what
+would normally be the @code{REAL(KIND=1)} (default @code{REAL}) type.
+(This affects @code{COMPLEX} the same way.)
+
+They also typically offer another option (@samp{-i8}) to increase
+@code{INTEGER} entities so they are twice as large
+(with roughly twice as much range).
+
+(There are potential pitfalls in using these options.)
+
+@code{g77} does not yet offer any option that performs these
+kinds of transformations.
+Part of the problem is the lack of detailed specifications regarding
+exactly how these options affect the interpretation of constants,
+intrinsics, and so on.
+
+Until @code{g77} addresses this need, programmers could improve
+the portability of their code by modifying it to not require
+compile-time options to produce correct results.
+Some free tools are available which may help, specifically
+in Toolpack (which one would expect to be sound) and the @file{fortran}
+section of the Netlib repository.
+
+Use of preprocessors can provide a fairly portable means
+to work around the lack of widely portable methods in the Fortran
+language itself (though increasing acceptance of Fortran 90 would
+alleviate this problem).

+for @emph{all} applicable back-end-supported types (@code{char}, @code{short int},
+@code{int}, @code{long int}, @code{long long int}, and @code{long double}).
+This means providing intrinsic support, and maybe constant

+

+@subsection POINTER Statements
+@cindex POINTER statement

+@code{g77} doesn't support pointers or allocatable objects
+(other than automatic arrays).
+This set of features is
+probably considered just behind intrinsics
+in @code{PARAMETER} statements on the list of large,
+important things to add to @code{g77}.
+
+In the meantime, consider using the @code{INTEGER(KIND=7)}
+declaration to specify that a variable must be
+able to hold a pointer.
+This construct is not portable to other non-GNU compilers,
+but it is portable to all machines GNU Fortran supports
+when @code{g77} is used.
+
+@xref{Functions and Subroutines}, for information on
+@code{%VAL()}, @code{%REF()}, and @code{%DESCR()}
+constructs, which are useful for passing pointers to

+
+@node Sensible Non-standard Constructs
+@subsection Sensible Non-standard Constructs
+
+@code{g77} rejects things other compilers accept,
+like @samp{INTRINSIC SQRT,SQRT}.
+As time permits in the future, some of these things that are easy for
+humans to read and write and unlikely to be intended to mean something
+else will be accepted by @code{g77} (though @samp{-fpedantic} should
+trigger warnings about such non-standard constructs).
+
+Until @code{g77} no longer gratuitously rejects sensible code,
+you might as well fix your code
+to be more standard-conforming and portable.
+
+The kind of case that is important to except from the
+recommendation to change your code is one where following
+good coding rules would force you to write non-standard
+code that nevertheless has a clear meaning.
+
+For example, when writing an @code{INCLUDE} file that
+defines a common block, it might be appropriate to
+include a @code{SAVE} statement for the common block
+(such as @samp{SAVE /CBLOCK/}), so that variables
+defined in the common block retain their values even
+when all procedures declaring the common block become
+inactive (return to their callers).
+
+However, putting @code{SAVE} statements in an @code{INCLUDE}
+file would prevent otherwise standard-conforming code
+from also specifying the @code{SAVE} statement, by itself,
+to indicate that all local variables and arrays are to
+have the @code{SAVE} attribute.
+
+For this reason, @code{g77} already has been changed to
+allow this combination, because although the general
+problem of gratuitously rejecting unambiguous and
+``safe'' constructs still exists in @code{g77}, this
+particular construct was deemed useful enough that
+it was worth fixing @code{g77} for just this case.
+
+So, while there is no need to change your code
+to avoid using this particular construct, there
+might be other, equally appropriate but non-standard
+constructs, that you shouldn't have to stop using
+just because @code{g77} (or any other compiler)
+gratuitously rejects it.
+
+Until the general problem is solved, if you have
+any such construct you believe is worthwhile
+using (e.g. not just an arbitrary, redundant
+specification of an attribute), please submit a
+bug report with an explanation, so we can consider
+fixing @code{g77} just for cases like yours.
+
+@node FLUSH Statement
+@subsection @code{FLUSH} Statement
+
+@code{g77} could perhaps use a @code{FLUSH} statement that
+does what @samp{CALL FLUSH} does,
+but that supports @samp{*} as the unit designator (same unit as for
+@code{PRINT}) and accepts @code{ERR=} and/or @code{IOSTAT=}
+specifiers.
+
+@node Expressions in FORMAT Statements
+@subsection Expressions in @code{FORMAT} Statements
+@cindex FORMAT statement
+@cindex statements, FORMAT
+
+@code{g77} doesn't support @samp{FORMAT(I<J>)} and the like.
+Supporting this requires a significant redesign or replacement
+of @code{libg2c}.
+
+However, @code{g77} does support
+this construct when the expression is constant
+(as of version 0.5.22).
+For example:
+
+@smallexample
+      PARAMETER (IWIDTH = 12)
+10    FORMAT (I<IWIDTH>)
+@end smallexample
+
+Otherwise, at least for output (@code{PRINT} and
+@code{WRITE}), Fortran code making use of this feature can
+be rewritten to avoid it by constructing the @code{FORMAT}
+string in a @code{CHARACTER} variable or array, then
+using that variable or array in place of the @code{FORMAT}
+statement label to do the original @code{PRINT} or @code{WRITE}.
+
+Many uses of this feature on input can be rewritten this way
+as well, but not all can.
+For example, this can be rewritten:
+
+@smallexample
+      READ 20, I
+20    FORMAT (I<J>)
+@end smallexample
+
+However, this cannot, in general, be rewritten, especially

+of the character constant, but Digital Fortran normally didn't,
+leaving only one space between @samp{MANY} and @samp{SPACES?}
+in the output of the above statement.
+
+Fairly recently, at least one version of Digital Fortran
+was enhanced to provide the other behavior when a
+command-line option is specified, apparently due to demand
+from readers of the USENET group @file{comp.lang.fortran}

+
+The @code{gcc} backend and, consequently, @code{g77}, currently provides no
+general control over whether or not floating-point exceptions are trapped or

+(Ignoring them typically results in NaN values being
+propagated in systems that conform to IEEE 754.)
+The behaviour is normally inherited from the system-dependent startup
+code, though some targets, such as the Alpha, have code generation
+options which change the behaviour.
+
+Most systems provide some C-callable mechanism to change this; this can
+be invoked at startup using @code{gcc}'s @code{constructor} attribute.
+For example, just compiling and linking the following C code with your
+program will turn on exception trapping for the ``common'' exceptions
+on an x86-based GNU system:
+
+@smallexample
+#include <fpu_control.h>

+@cindex unformatted files

+@cindex binary data
+@cindex byte ordering
+@code{g77} has no facility for exchanging unformatted files with systems
+using different number formats---even differing only in endianness (byte
+order)---or written by other compilers.  Some compilers provide
+facilities at least for doing byte-swapping during unformatted I/O.
+
+It is unrealistic to expect to cope with exchanging unformatted files
+with arbitrary other compiler runtimes, but the @code{g77} runtime
+should at least be able to read files written by @code{g77} on systems
+with different number formats, particularly if they differ only in byte
+order.
+
+In case you do need to write a program to translate to or from
+@code{g77} (@code{libf2c}) unformatted files, they are written as
+follows:
+@table @asis
+@item Sequential
+Unformatted sequential records consist of
+@enumerate
+@item
+A number giving the length of the record contents;
+@item
+the length of record contents again (for backspace).
+@end enumerate
+The record length is of C type
+@code{long}; this means that it is 8 bytes on 64-bit systems such as
+Alpha GNU/Linux and 4 bytes on other systems, such as x86 GNU/Linux.
+Consequently such files cannot be exchanged between 64-bit and 32-bit
+systems, even with the same basic number format.
+@item Direct access
+Unformatted direct access files form a byte stream of length
+@var{records}*@var{recl} bytes, where @var{records} is the maximum
+record number (@code{REC=@var{records}}) written and @var{recl} is the
+record length in bytes specified in the @code{OPEN} statement
+(@code{RECL=@var{recl}}).  Data appear in the records as determined by
+the relevant @code{WRITE} statement.  Dummy records with arbitrary
+contents appear in the file in place of records which haven't been
+written.
+@end table
+
+Thus for exchanging a sequential or direct access unformatted file
+between big- and little-endian 32-bit systems using IEEE 754 floating
+point it would be sufficient to reverse the bytes in consecutive words
+in the file @emph{iff} only @code{REAL*4}, @code{COMPLEX},
+@code{INTEGER*4} and/or @code{LOGICAL*4} data have been written to it by
+@code{g77}.
+
+If necessary, it is possible to do byte-oriented i/o with @code{g77}'s
+@code{FGETC} and @code{FPUTC} intrinsics.  Byte-swapping can be done in
+Fortran by equivalencing larger sized variables to an @code{INTEGER*1}
+array or a set of scalars.

+@cindex f77 support
+@cindex support, f77
+
+In the opinion of many experienced Fortran users,
+@samp{-fno-backslash} should be the default, not @samp{-fbackslash},
+as currently set by @code{g77}.
+
+First of all, you can always specify
+@samp{-fno-backslash} to turn off this processing.
+
+Despite not being within the spirit (though apparently within the
+letter) of the ANSI FORTRAN 77 standard, @code{g77} defaults to
+@samp{-fbackslash} because that is what most UNIX @code{f77} commands
+default to, and apparently lots of code depends on this feature.
+
+This is a particularly troubling issue.
+The use of a C construct in the midst of Fortran code
+is bad enough, worse when it makes existing Fortran
+programs stop working (as happens when programs written
+for non-UNIX systems are ported to UNIX systems with
+compilers that provide the @samp{-fbackslash} feature
+as the default---sometimes with no option to turn it off).
+
+The author of GNU Fortran wished, for reasons of linguistic
+purity, to make @samp{-fno-backslash} the default for GNU
+Fortran and thus require users of UNIX @code{f77} and @code{f2c}
+to specify @samp{-fbackslash} to get the UNIX behavior.
+
+However, the realization that @code{g77} is intended as
+a replacement for @emph{UNIX} @code{f77}, caused the author
+to choose to make @code{g77} as compatible with
+@code{f77} as feasible, which meant making @samp{-fbackslash}
+the default.
+
+The primary focus on compatibility is at the source-code
+level, and the question became ``What will users expect
+a replacement for @code{f77} to do, by default?''
+Although at least one UNIX @code{f77} does not provide
+@samp{-fbackslash} as a default, it appears that
+the majority of them do, which suggests that
+the majority of code that is compiled by UNIX @code{f77}
+compilers expects @samp{-fbackslash} to be the default.
+
+It is probably the case that more code exists
+that would @emph{not} work with @samp{-fbackslash}
+in force than code that requires it be in force.
+
+However, most of @emph{that} code is not being compiled
+with @code{f77},
+and when it is, new build procedures (shell scripts,
+makefiles, and so on) must be set up anyway so that
+they work under UNIX.
+That makes a much more natural and safe opportunity for
+non-UNIX users to adapt their build procedures for
+@code{g77}'s default of @samp{-fbackslash} than would
+exist for the majority of UNIX @code{f77} users who
+would have to modify existing, working build procedures
+to explicitly specify @samp{-fbackslash} if that was
+not the default.
+
+One suggestion has been to configure the default for
+@samp{-fbackslash} (and perhaps other options as well)
+based on the configuration of @code{g77}.
+
+This is technically quite straightforward, but will be avoided
+even in cases where not configuring defaults to be
+dependent on a particular configuration greatly inconveniences
+some users of legacy code.
+
+Many users appreciate the GNU compilers because they provide an
+environment that is uniform across machines.
+These users would be
+inconvenienced if the compiler treated things like the
+format of the source code differently on certain machines.
+
+Occasionally users write programs intended only for a particular machine
+type.
+On these occasions, the users would benefit if the GNU Fortran compiler
+were to support by default the same dialect as the other compilers on
+that machine.
+But such applications are rare.
+And users writing a
+program to run on more than one type of machine cannot possibly benefit
+from this kind of compatibility.
+(This is consistent with the design goals for @code{gcc}.
+To change them for @code{g77}, you must first change them
+for @code{gcc}.
+Do not ask the maintainers of @code{g77} to do this for you,
+or to disassociate @code{g77} from the widely understood, if
+not widely agreed-upon, goals for GNU compilers in general.)
+
+This is why GNU Fortran does and will treat backslashes in the same
+fashion on all types of machines (by default).
+@xref{Direction of Language Development}, for more information on
+this overall philosophy guiding the development of the GNU Fortran
+language.
+
+Of course, users strongly concerned about portability should indicate
+explicitly in their build procedures which options are expected
+by their source code, or write source code that has as few such
+expectations as possible.
+
+For example, avoid writing code that depends on backslash (@samp{\})
+being interpreted either way in particular, such as by
+starting a program unit with:
+
+@smallexample
+CHARACTER BACKSL
+PARAMETER (BACKSL = '\\')
+@end smallexample
+
+@noindent
+Then, use concatenation of @samp{BACKSL} anyplace a backslash
+is desired.
+In this way, users can write programs which have the same meaning
+in many Fortran dialects.
+
+(However, this technique does not work for Hollerith constants---which
+is just as well, since the only generally portable uses for Hollerith
+constants are in places where character constants can and should
+be used instead, for readability.)

+@code{g77} does not allow @samp{DATA VAR/1/} to appear in the

+In general, @code{g77} requires initialization of a variable

+

+so that it can possibly immediately write constants

+

+
+@code{g77} treats procedure references to @emph{possible} intrinsic
+names as always enabling their intrinsic nature, regardless of
+whether the @emph{form} of the reference is valid for that
+intrinsic.
+
+For example, @samp{CALL SQRT} is interpreted by @code{g77} as
+an invalid reference to the @code{SQRT} intrinsic function,
+because the reference is a subroutine invocation.
+
+First, @code{g77} recognizes the statement @samp{CALL SQRT}
+as a reference to a @emph{procedure} named @samp{SQRT}, not
+to a @emph{variable} with that name (as it would for a statement
+such as @samp{V = SQRT}).
+
+Next, @code{g77} establishes that, in the program unit being compiled,
+@code{SQRT} is an intrinsic---not a subroutine that
+happens to have the same name as an intrinsic (as would be
+the case if, for example, @samp{EXTERNAL SQRT} was present).
+
+Finally, @code{g77} recognizes that the @emph{form} of the
+reference is invalid for that particular intrinsic.
+That is, it recognizes that it is invalid for an intrinsic
+@emph{function}, such as @code{SQRT}, to be invoked as
+a @emph{subroutine}.
+
+At that point, @code{g77} issues a diagnostic.
+
+Some users claim that it is ``obvious'' that @samp{CALL SQRT}
+references an external subroutine of their own, not an
+intrinsic function.
+
+However, @code{g77} knows about intrinsic
+subroutines, not just functions, and is able to support both having
+the same names, for example.
+
+As a result of this, @code{g77} rejects calls
+to intrinsics that are not subroutines, and function invocations
+of intrinsics that are not functions, just as it (and most compilers)
+rejects invocations of intrinsics with the wrong number (or types)
+of arguments.
+
+So, use the @samp{EXTERNAL SQRT} statement in a program unit that calls
+a user-written subroutine named @samp{SQRT}.
+
+@node Context-Sensitive Constants
+@subsection Context-Sensitive Constants
+@cindex constants, context-sensitive
+@cindex context-sensitive constants
+
+@code{g77} does not use context to determine the types of
+constants or named constants (@code{PARAMETER}), except
+for (non-standard) typeless constants such as @samp{'123'O}.
+
+For example, consider the following statement:
+
+@smallexample
+PRINT *, 9.435784839284958 * 2D0
+@end smallexample
+
+@noindent
+@code{g77} will interpret the (truncated) constant
+@samp{9.435784839284958} as a @code{REAL(KIND=1)}, not @code{REAL(KIND=2)},
+constant, because the suffix @code{D0} is not specified.
+
+As a result, the output of the above statement when
+compiled by @code{g77} will appear to have ``less precision''
+than when compiled by other compilers.
+
+In these and other cases, some compilers detect the
+fact that a single-precision constant is used in
+a double-precision context and therefore interpret the
+single-precision constant as if it was @emph{explicitly}
+specified as a double-precision constant.
+(This has the effect of appending @emph{decimal}, not
+@emph{binary}, zeros to the fractional part of the
+number---producing different computational results.)
+
+The reason this misfeature is dangerous is that a slight,
+apparently innocuous change to the source code can change
+the computational results.
+Consider:
+
+@smallexample
+REAL ALMOST, CLOSE
+DOUBLE PRECISION FIVE
+PARAMETER (ALMOST = 5.000000000001)
+FIVE = 5
+CLOSE = 5.000000000001
+PRINT *, 5.000000000001 - FIVE
+PRINT *, ALMOST - FIVE
+PRINT *, CLOSE - FIVE
+END
+@end smallexample
+
+@noindent
+Running the above program should
+result in the same value being
+printed three times.
+With @code{g77} as the compiler,
+it does.
+
+However, compiled by many other compilers,
+running the above program would print
+two or three distinct values, because
+in two or three of the statements, the
+constant @samp{5.000000000001}, which
+on most systems is exactly equal to @samp{5.}
+when interpreted as a single-precision constant,
+is instead interpreted as a double-precision
+constant, preserving the represented
+precision.
+However, this ``clever'' promotion of
+type does not extend to variables or,
+in some compilers, to named constants.
+
+Since programmers often are encouraged to replace manifest
+constants or permanently-assigned variables with named
+constants (@code{PARAMETER} in Fortran), and might need
+to replace some constants with variables having the same
+values for pertinent portions of code,
+it is important that compilers treat code so modified in the
+same way so that the results of such programs are the same.
+@code{g77} helps in this regard by treating constants just
+the same as variables in terms of determining their types
+in a context-independent way.
+
+Still, there is a lot of existing Fortran code that has
+been written to depend on the way other compilers freely
+interpret constants' types based on context, so anything
+@code{g77} can do to help flag cases of this in such code
+could be very helpful.
+
+@node Equivalence Versus Equality
+@subsection Equivalence Versus Equality
+@cindex .EQV., with integer operands
+@cindex comparing logical expressions
+@cindex logical expressions, comparing
+
+Use of @code{.EQ.} and @code{.NE.} on @code{LOGICAL} operands
+is not supported, except via @samp{-fugly}, which is not
+recommended except for legacy code (where the behavior expected
+by the @emph{code} is assumed).
+
+Legacy code should be changed, as resources permit, to use @code{.EQV.}
+and @code{.NEQV.} instead, as these are permitted by the various
+Fortran standards.
+
+New code should never be written expecting @code{.EQ.} or @code{.NE.}
+to work if either of its operands is @code{LOGICAL}.
+
+The problem with supporting this ``feature'' is that there is
+unlikely to be consensus on how it works, as illustrated by the
+following sample program:
+
+@smallexample
+LOGICAL L,M,N
+DATA L,M,N /3*.FALSE./
+IF (L.AND.M.EQ.N) PRINT *,'L.AND.M.EQ.N'
+END
+@end smallexample
+
+The issue raised by the above sample program is: what is the
+precedence of @code{.EQ.} (and @code{.NE.}) when applied to
+@code{LOGICAL} operands?
+
+Some programmers will argue that it is the same as the precedence
+for @code{.EQ.} when applied to numeric (such as @code{INTEGER})
+operands.
+By this interpretation, the subexpression @samp{M.EQ.N} must be
+evaluated first in the above program, resulting in a program that,
+when run, does not execute the @code{PRINT} statement.
+
+Other programmers will argue that the precedence is the same as
+the precedence for @code{.EQV.}, which is restricted by the standards
+to @code{LOGICAL} operands.
+By this interpretation, the subexpression @samp{L.AND.M} must be
+evaluated first, resulting in a program that @emph{does} execute
+the @code{PRINT} statement.
+
+Assigning arbitrary semantic interpretations to syntactic expressions
+that might legitimately have more than one ``obvious'' interpretation
+is generally unwise.
+
+The creators of the various Fortran standards have done a good job
+in this case, requiring a distinct set of operators (which have their
+own distinct precedence) to compare @code{LOGICAL} operands.
+This requirement results in expression syntax with more certain
+precedence (without requiring substantial context), making it easier
+for programmers to read existing code.
+@code{g77} will avoid muddying up elements of the Fortran language
+that were well-designed in the first place.
+
+(Ask C programmers about the precedence of expressions such as
+@samp{(a) & (b)} and @samp{(a) - (b)}---they cannot even tell
+you, without knowing more context, whether the @samp{&} and @samp{-}
+operators are infix (binary) or unary!)
+
+@node Order of Side Effects
+@subsection Order of Side Effects
+@cindex side effects, order of evaluation
+@cindex order of evaluation, side effects
+
+@code{g77} does not necessarily produce code that, when run, performs
+side effects (such as those performed by function invocations)
+in the same order as in some other compiler---or even in the same
+order as another version, port, or invocation (using different
+command-line options) of @code{g77}.
+
+It is never safe to depend on the order of evaluation of side effects.
+For example, an expression like this may very well behave differently
+from one compiler to another:
+
+@smallexample
+J = IFUNC() - IFUNC()
+@end smallexample
+
+@noindent
+There is no guarantee that @samp{IFUNC} will be evaluated in any particular
+order.
+Either invocation might happen first.
+If @samp{IFUNC} returns 5 the first time it is invoked, and
+returns 12 the second time, @samp{J} might end up with the
+value @samp{7}, or it might end up with @samp{-7}.
+
+Generally, in Fortran, procedures with side-effects intended to
+be visible to the caller are best designed as @emph{subroutines},
+not functions.
+Examples of such side-effects include:
+
+@itemize @bullet
+@item
+The generation of random numbers
+that are intended to influence return values.
+
+@item
+Performing I/O
+(other than internal I/O to local variables).
+
+@item
+Updating information in common blocks.
+@end itemize
+
+An example of a side-effect that is not intended to be visible
+to the caller is a function that maintains a cache of recently
+calculated results, intended solely to speed repeated invocations
+of the function with identical arguments.
+Such a function can be safely used in expressions, because
+if the compiler optimizes away one or more calls to the
+function, operation of the program is unaffected (aside
+from being speeded up).

+@node Warnings and Errors
+@section Warning Messages and Error Messages
+
+@cindex error messages
+@cindex warnings vs errors
+@cindex messages, warning and error
+The GNU compiler can produce two kinds of diagnostics: errors and
+warnings.
+Each kind has a different purpose:
+
+@itemize @w{}
+@item 
+@emph{Errors} report problems that make it impossible to compile your
+program.
+GNU Fortran reports errors with the source file name, line
+number, and column within the line where the problem is apparent.
+
+@item
+@emph{Warnings} report other unusual conditions in your code that
+@emph{might} indicate a problem, although compilation can (and does)
+proceed.
+Warning messages also report the source file name, line number,
+and column information,
+but include the text @samp{warning:} to distinguish them
+from error messages.
+@end itemize
+
+Warnings might indicate danger points where you should check to make sure
+that your program really does what you intend; or the use of obsolete
+features; or the use of nonstandard features of GNU Fortran.
+Many warnings are issued only if you ask for them, with one of the
+@samp{-W} options (for instance, @samp{-Wall} requests a variety of
+useful warnings).
+
+@emph{Note:} Currently, the text of the line and a pointer to the column
+is printed in most @code{g77} diagnostics.
+Probably, as of version 0.6, @code{g77} will
+no longer print the text of the source line, instead printing
+the column number following the file name and line number in
+a form that GNU Emacs recognizes.
+This change is expected to speed up and reduce the memory usage
+of the @code{g77} compiler.
+@c
+@c Say this when it is true -- hopefully 0.6, maybe 0.7 or later.  --burley
+@c
+@c GNU Fortran always tries to compile your program if possible; it never
+@c gratuitously rejects a program whose meaning is clear merely because
+@c (for instance) it fails to conform to a standard.  In some cases,
+@c however, the Fortran standard specifies that certain extensions are
+@c forbidden, and a diagnostic @emph{must} be issued by a conforming
+@c compiler.  The @samp{-pedantic} option tells GNU Fortran to issue warnings
+@c in such cases; @samp{-pedantic-errors} says to make them errors instead.
+@c This does not mean that @emph{all} non-ANSI constructs get warnings
+@c or errors.

+
+When you encounter a problem, the first thing to do is to see if it is

+@xref{Trouble}.
+If it isn't known, then you should report the problem.
+
+Reporting a bug might help you by bringing a solution to your problem, or

+Bug reports are your contribution to the maintenance of GNU Fortran.
+
+Since the maintainers are very overloaded, we cannot respond to every

+However, if the bug has not been fixed, we are likely to

+If you are not sure whether you have found a bug, here are some guidelines:
+
+@itemize @bullet
+@cindex fatal signal
+@cindex core dump
+@item
+If the compiler gets a fatal signal, for any input whatever, that is a
+compiler bug.
+Reliable compilers never crash---they just remain obsolete.
+
+@cindex invalid assembly code
+@cindex assembly code, invalid
+@item
+If the compiler produces invalid assembly code, for any input whatever,
+@c (except an @code{asm} statement),
+that is a compiler bug, unless the
+compiler reports errors (not just warnings) which would ordinarily
+prevent the assembler from being run.
+
+@cindex undefined behavior
+@cindex undefined function value
+@item
+If the compiler produces valid assembly code that does not correctly
+execute the input source code, that is a compiler bug.
+
+However, you must double-check to make sure, because you might have run
+into an incompatibility between GNU Fortran and traditional Fortran.
+@c (@pxref{Incompatibilities}).
+These incompatibilities might be considered
+bugs, but they are inescapable consequences of valuable features.
+
+Or you might have a program whose behavior is undefined, which happened
+by chance to give the desired results with another Fortran compiler.
+It is best to check the relevant Fortran standard thoroughly if
+it is possible that the program indeed does something undefined.
+
+After you have localized the error to a single source line, it should
+be easy to check for these things.
+If your program is correct and well defined, you have found
+a compiler bug.
+
+It might help if, in your submission, you identified the specific
+language in the relevant Fortran standard that specifies the
+desired behavior, if it isn't likely to be obvious and agreed-upon
+by all Fortran users.
+
+@item
+If the compiler produces an error message for valid input, that is a
+compiler bug.
+
+@cindex invalid input
+@item
+If the compiler does not produce an error message for invalid input,
+that is a compiler bug.
+However, you should note that your idea of
+``invalid input'' might be someone else's idea
+of ``an extension'' or ``support for traditional practice''.
+
+@item
+If you are an experienced user of Fortran compilers, your suggestions
+for improvement of GNU Fortran are welcome in any case.
+@end itemize
+
+Many, perhaps most, bug reports against @code{g77} turn out to
+be bugs in the user's code.
+While we find such bug reports educational, they sometimes take
+a considerable amount of time to track down or at least respond
+to---time we could be spending making @code{g77}, not some user's
+code, better.
+
+Some steps you can take to verify that the bug is not certainly
+in the code you're compiling with @code{g77}:
+
+@itemize @bullet
+@item
+Compile your code using the @code{g77} options @samp{-W -Wall -O}.
+These options enable many useful warning; the @samp{-O} option
+enables flow analysis that enables the uninitialized-variable
+warning.
+
+If you investigate the warnings and find evidence of possible bugs
+in your code, fix them first and retry @code{g77}.
+
+@item
+Compile your code using the @code{g77} options @samp{-finit-local-zero},
+@samp{-fno-automatic}, @samp{-ffloat-store}, and various
+combinations thereof.
+
+If your code works with any of these combinations, that is not
+proof that the bug isn't in @code{g77}---a @code{g77} bug exposed
+by your code might simply be avoided, or have a different, more subtle
+effect, when different options are used---but it can be a
+strong indicator that your code is making unwarranted assumptions
+about the Fortran dialect and/or underlying machine it is
+being compiled and run on.

+@node Bug Reporting
+@section How to Report Bugs
+@cindex compiler bugs, reporting
+
+The fundamental principle of reporting bugs usefully is this:
+@strong{report all the facts}.
+If you are not sure whether to state a
+fact or leave it out, state it!
+
+Often people omit facts because they think they know what causes the
+problem and they conclude that some details don't matter.
+Thus, you might
+assume that the name of the variable you use in an example does not matter.
+Well, probably it doesn't, but one cannot be sure.
+Perhaps the bug is a
+stray memory reference which happens to fetch from the location where that
+name is stored in memory; perhaps, if the name were different, the contents
+of that location would fool the compiler into doing the right thing despite
+the bug.
+Play it safe and give a specific, complete example.
+That is the
+easiest thing for you to do, and the most helpful.
+
+Keep in mind that the purpose of a bug report is to enable someone to
+fix the bug if it is not known.
+It isn't very important what happens if
+the bug is already known.
+Therefore, always write your bug reports on
+the assumption that the bug is not known.
+
+Sometimes people give a few sketchy facts and ask, ``Does this ring a
+bell?''
+This cannot help us fix a bug, so it is rarely helpful.
+We respond by asking for enough details to enable us to investigate.
+You might as well expedite matters by sending them to begin with.
+(Besides, there are enough bells ringing around here as it is.)
+
+Try to make your bug report self-contained.
+If we have to ask you for
+more information, it is best if you include all the previous information
+in your response, as well as the information that was missing.
+
+Please report each bug in a separate message.
+This makes it easier for
+us to track which bugs have been fixed and to forward your bugs reports
+to the appropriate maintainer.
+
+Do not compress and encode any part of your bug report using programs
+such as @file{uuencode}.
+If you do so it will slow down the processing
+of your bug.
+If you must submit multiple large files, use @file{shar},
+which allows us to read your message without having to run any
+decompression programs.
+
+(As a special exception for GNU Fortran bug-reporting, at least
+for now, if you are sending more than a few lines of code, if
+your program's source file format contains ``interesting'' things
+like trailing spaces or strange characters, or if you need to
+include binary data files, it is acceptable to put all the
+files together in a @code{tar} archive, and, whether you need to
+do that, it is acceptable to then compress the single file (@code{tar}
+archive or source file)
+using @code{gzip} and encode it via @code{uuencode}.
+Do not use any MIME stuff---the current maintainer can't decode this.
+Using @code{compress} instead of @code{gzip} is acceptable, assuming
+you have licensed the use of the patented algorithm in
+@code{compress} from Unisys.)
+
+To enable someone to investigate the bug, you should include all these
+things:
+
+@itemize @bullet
+@item
+The version of GNU Fortran.
+You can get this by running @code{g77} with the @samp{-v} option.
+(Ignore any error messages that might be displayed
+when the linker is run.)
+
+Without this, we won't know whether there is any point in looking for
+the bug in the current version of GNU Fortran.
+
+@item
+@cindex preprocessor
+@cindex cpp program
+@cindex programs, cpp
+@pindex cpp
+A complete input file that will reproduce the bug.
+If the bug is in the compiler proper (@file{f771}) and
+you are using the C preprocessor, run your
+source file through the C preprocessor by doing @samp{g77 -E
+@var{sourcefile} > @var{outfile}}, then include the contents of
+@var{outfile} in the bug report.  (When you do this, use the same
+@samp{-I}, @samp{-D} or @samp{-U} options that you used in actual
+compilation.)
+
+A single statement is not enough of an example.
+In order to compile it,
+it must be embedded in a complete file of compiler input; and the bug
+might depend on the details of how this is done.
+
+Without a real example one can compile, all anyone can do about your bug
+report is wish you luck.  It would be futile to try to guess how to
+provoke the bug.  For example, bugs in register allocation and reloading
+frequently depend on every little detail of the function they happen in.
+
+@item
+@cindex included files
+@cindex INCLUDE directive
+@cindex directive, INCLUDE
+@cindex #include directive
+@cindex directive, #include
+Note that you should include with your bug report any files
+included by the source file
+(via the @code{#include} or @code{INCLUDE} directive)
+that you send, and any files they include, and so on.
+
+It is not necessary to replace
+the @code{#include} and @code{INCLUDE} directives
+with the actual files in the version of the source file that
+you send, but it might make submitting the bug report easier
+in the end.
+However, be sure to @emph{reproduce} the bug using the @emph{exact}
+version of the source material you submit, to avoid wild-goose
+chases.
+
+@item
+The command arguments you gave GNU Fortran to compile that example
+and observe the bug.  For example, did you use @samp{-O}?  To guarantee
+you won't omit something important, list all the options.
+
+If we were to try to guess the arguments, we would probably guess wrong
+and then we would not encounter the bug.
+
+@item
+The type of machine you are using, and the operating system name and
+version number.
+(Much of this information is printed by @samp{g77 -v}---if you
+include that, send along any additional info you have that you
+don't see clearly represented in that output.)
+
+@item
+The operands you gave to the @code{configure} command when you installed
+the compiler.
+
+@item
+A complete list of any modifications you have made to the compiler
+source.  (We don't promise to investigate the bug unless it happens in
+an unmodified compiler.  But if you've made modifications and don't tell
+us, then you are sending us on a wild-goose chase.)
+
+Be precise about these changes.  A description in English is not
+enough---send a context diff for them.
+
+Adding files of your own (such as a machine description for a machine we
+don't support) is a modification of the compiler source.
+
+@item
+Details of any other deviations from the standard procedure for installing
+GNU Fortran.
+
+@item
+A description of what behavior you observe that you believe is
+incorrect.  For example, ``The compiler gets a fatal signal,'' or,
+``The assembler instruction at line 208 in the output is incorrect.''
+
+Of course, if the bug is that the compiler gets a fatal signal, then one
+can't miss it.  But if the bug is incorrect output, the maintainer might
+not notice unless it is glaringly wrong.  None of us has time to study
+all the assembler code from a 50-line Fortran program just on the chance that
+one instruction might be wrong.  We need @emph{you} to do this part!
+
+Even if the problem you experience is a fatal signal, you should still
+say so explicitly.  Suppose something strange is going on, such as, your
+copy of the compiler is out of synch, or you have encountered a bug in
+the C library on your system.  (This has happened!)  Your copy might
+crash and the copy here would not.  If you @i{said} to expect a crash,
+then when the compiler here fails to crash, we would know that the bug
+was not happening.  If you don't say to expect a crash, then we would
+not know whether the bug was happening.  We would not be able to draw
+any conclusion from our observations.
+
+If the problem is a diagnostic when building GNU Fortran with some other
+compiler, say whether it is a warning or an error.
+
+Often the observed symptom is incorrect output when your program is run.
+Sad to say, this is not enough information unless the program is short
+and simple.  None of us has time to study a large program to figure out
+how it would work if compiled correctly, much less which line of it was
+compiled wrong.  So you will have to do that.  Tell us which source line
+it is, and what incorrect result happens when that line is executed.  A
+person who understands the program can find this as easily as finding a
+bug in the program itself.
+
+@item
+If you send examples of assembler code output from GNU Fortran,
+please use @samp{-g} when you make them.  The debugging information
+includes source line numbers which are essential for correlating the
+output with the input.
+
+@item
+If you wish to mention something in the GNU Fortran source, refer to it by
+context, not by line number.
+
+The line numbers in the development sources don't match those in your
+sources.  Your line numbers would convey no convenient information to the
+maintainers.
+
+@item
+Additional information from a debugger might enable someone to find a
+problem on a machine which he does not have available.  However, you
+need to think when you collect this information if you want it to have
+any chance of being useful.
+
+@cindex backtrace for bug reports
+For example, many people send just a backtrace, but that is never
+useful by itself.  A simple backtrace with arguments conveys little
+about GNU Fortran because the compiler is largely data-driven; the same
+functions are called over and over for different RTL insns, doing
+different things depending on the details of the insn.
+
+Most of the arguments listed in the backtrace are useless because they
+are pointers to RTL list structure.  The numeric values of the
+pointers, which the debugger prints in the backtrace, have no
+significance whatever; all that matters is the contents of the objects
+they point to (and most of the contents are other such pointers).
+
+In addition, most compiler passes consist of one or more loops that
+scan the RTL insn sequence.  The most vital piece of information about
+such a loop---which insn it has reached---is usually in a local variable,
+not in an argument.
+
+@findex debug_rtx
+What you need to provide in addition to a backtrace are the values of
+the local variables for several stack frames up.  When a local
+variable or an argument is an RTX, first print its value and then use
+the GDB command @code{pr} to print the RTL expression that it points
+to.  (If GDB doesn't run on your machine, use your debugger to call
+the function @code{debug_rtx} with the RTX as an argument.)  In
+general, whenever a variable is a pointer, its value is no use
+without the data it points to.
+@end itemize
+
+Here are some things that are not necessary:
+
+@itemize @bullet
+@item
+A description of the envelope of the bug.
+
+Often people who encounter a bug spend a lot of time investigating
+which changes to the input file will make the bug go away and which
+changes will not affect it.
+
+This is often time consuming and not very useful, because the way we
+will find the bug is by running a single example under the debugger with
+breakpoints, not by pure deduction from a series of examples.  You might
+as well save your time for something else.
+
+Of course, if you can find a simpler example to report @emph{instead} of
+the original one, that is a convenience.  Errors in the output will be
+easier to spot, running under the debugger will take less time, etc.
+Most GNU Fortran bugs involve just one function, so the most straightforward
+way to simplify an example is to delete all the function definitions
+except the one where the bug occurs.  Those earlier in the file may be
+replaced by external declarations if the crucial function depends on
+them.  (Exception: inline functions might affect compilation of functions
+defined later in the file.)
+
+However, simplification is not vital; if you don't want to do this,
+report the bug anyway and send the entire test case you used.
+
+@item
+In particular, some people insert conditionals @samp{#ifdef BUG} around
+a statement which, if removed, makes the bug not happen.  These are just
+clutter; we won't pay any attention to them anyway.  Besides, you should
+send us preprocessor output, and that can't have conditionals.
+
+@item
+A patch for the bug.
+
+A patch for the bug is useful if it is a good one.  But don't omit the
+necessary information, such as the test case, on the assumption that a
+patch is all we need.  We might see problems with your patch and decide
+to fix the problem another way, or we might not understand it at all.
+
+Sometimes with a program as complicated as GNU Fortran it is very hard to
+construct an example that will make the program follow a certain path
+through the code.  If you don't send the example, we won't be able to
+construct one, so we won't be able to verify that the bug is fixed.
+
+And if we can't understand what bug you are trying to fix, or why your
+patch should be an improvement, we won't install it.  A test case will
+help us to understand.
+
+@xref{Sending Patches}, for guidelines on how to make it easy for us to
+understand and install your patches.
+
+@item
+A guess about what the bug is or what it depends on.
+
+Such guesses are usually wrong.  Even the maintainer can't guess right
+about such things without first using the debugger to find the facts.
+
+@item
+A core dump file.
+
+We have no way of examining a core dump for your type of machine
+unless we have an identical system---and if we do have one,
+we should be able to reproduce the crash ourselves.
+@end itemize
+
+@node Sending Patches
+@section Sending Patches for GNU Fortran
+
+If you would like to write bug fixes or improvements for the GNU Fortran
+compiler, that is very helpful.
+Send suggested fixes to the bug report
+mailing list, @email{@value{email-bugs}}.
+
+Please follow these guidelines so we can study your patches efficiently.
+If you don't follow these guidelines, your information might still be
+useful, but using it will take extra work.  Maintaining GNU Fortran is a lot
+of work in the best of circumstances, and we can't keep up unless you do
+your best to help.
+
+@itemize @bullet
+@item
+Send an explanation with your changes of what problem they fix or what
+improvement they bring about.  For a bug fix, just include a copy of the
+bug report, and explain why the change fixes the bug.
+
+(Referring to a bug report is not as good as including it, because then
+we will have to look it up, and we have probably already deleted it if
+we've already fixed the bug.)
+
+@item
+Always include a proper bug report for the problem you think you have
+fixed.  We need to convince ourselves that the change is right before
+installing it.  Even if it is right, we might have trouble judging it if
+we don't have a way to reproduce the problem.
+
+@item
+Include all the comments that are appropriate to help people reading the
+source in the future understand why this change was needed.
+
+@item
+Don't mix together changes made for different reasons.
+Send them @emph{individually}.
+
+If you make two changes for separate reasons, then we might not want to
+install them both.  We might want to install just one.  If you send them
+all jumbled together in a single set of diffs, we have to do extra work
+to disentangle them---to figure out which parts of the change serve
+which purpose.  If we don't have time for this, we might have to ignore
+your changes entirely.
+
+If you send each change as soon as you have written it, with its own
+explanation, then the two changes never get tangled up, and we can
+consider each one properly without any extra work to disentangle them.
+
+Ideally, each change you send should be impossible to subdivide into
+parts that we might want to consider separately, because each of its
+parts gets its motivation from the other parts.
+
+@item
+Send each change as soon as that change is finished.  Sometimes people
+think they are helping us by accumulating many changes to send them all
+together.  As explained above, this is absolutely the worst thing you
+could do.
+
+Since you should send each change separately, you might as well send it
+right away.  That gives us the option of installing it immediately if it
+is important.
+
+@item
+Use @samp{diff -c} to make your diffs.  Diffs without context are hard
+for us to install reliably.  More than that, they make it hard for us to
+study the diffs to decide whether we want to install them.  Unidiff
+format is better than contextless diffs, but not as easy to read as
+@samp{-c} format.
+
+If you have GNU @code{diff}, use @samp{diff -cp}, which shows the name of the
+function that each change occurs in.
+(The maintainer of GNU Fortran currently uses @samp{diff -rcp2N}.)
+
+@item
+Write the change log entries for your changes.  We get lots of changes,
+and we don't have time to do all the change log writing ourselves.
+
+Read the @file{ChangeLog} file to see what sorts of information to put
+in, and to learn the style that we use.  The purpose of the change log
+is to show people where to find what was changed.  So you need to be
+specific about what functions you changed; in large functions, it's
+often helpful to indicate where within the function the change was.
+
+On the other hand, once you have shown people where to find the change,
+you need not explain its purpose.  Thus, if you add a new function, all
+you need to say about it is that it is new.  If you feel that the
+purpose needs explaining, it probably does---but the explanation will be
+much more useful if you put it in comments in the code.
+
+If you would like your name to appear in the header line for who made
+the change, send us the header line.
+
+@item
+When you write the fix, keep in mind that we can't install a change that
+would break other systems.
+
+People often suggest fixing a problem by changing machine-independent
+files such as @file{toplev.c} to do something special that a particular
+system needs.  Sometimes it is totally obvious that such changes would
+break GNU Fortran for almost all users.  We can't possibly make a change like
+that.  At best it might tell us how to write another patch that would
+solve the problem acceptably.
+
+Sometimes people send fixes that @emph{might} be an improvement in
+general---but it is hard to be sure of this.  It's hard to install
+such changes because we have to study them very carefully.  Of course,
+a good explanation of the reasoning by which you concluded the change
+was correct can help convince us.
+
+The safest changes are changes to the configuration files for a
+particular machine.  These are safe because they can't create new bugs
+on other machines.
+
+Please help us keep up with the workload by designing the patch in a
+form that is good to install.

+@node Adding Options
+@chapter Adding Options
+@cindex options, adding
+@cindex adding options
+
+To add a new command-line option to @code{g77}, first decide
+what kind of option you wish to add.
+Search the @code{g77} and @code{gcc} documentation for one
+or more options that is most closely like the one you want to add
+(in terms of what kind of effect it has, and so on) to
+help clarify its nature.
+
+@itemize @bullet
+@item
+@emph{Fortran options} are options that apply only
+when compiling Fortran programs.
+They are accepted by @code{g77} and @code{gcc}, but
+they apply only when compiling Fortran programs.
+
+@item
+@emph{Compiler options} are options that apply
+when compiling most any kind of program.
+@end itemize
+
+@emph{Fortran options} are listed in the file
+@file{@value{path-g77}/lang-options.h},
+which is used during the build of @code{gcc} to
+build a list of all options that are accepted by
+at least one language's compiler.
+This list goes into the @samp{lang_options} array
+in @file{gcc/toplev.c}, which uses this array to
+determine whether a particular option should be
+offered to the linked-in front end for processing
+by calling @samp{lang_option_decode}, which, for
+@code{g77}, is in @file{@value{path-g77}/com.c} and just
+calls @samp{ffe_decode_option}.
+
+If the linked-in front end ``rejects'' a
+particular option passed to it, @file{toplev.c}
+just ignores the option, because @emph{some}
+language's compiler is willing to accept it.
+
+This allows commands like @samp{gcc -fno-asm foo.c bar.f}
+to work, even though Fortran compilation does
+not currently support the @samp{-fno-asm} option;
+even though the @code{f771} version of @samp{lang_decode_option}
+rejects @samp{-fno-asm}, @file{toplev.c} doesn't
+produce a diagnostic because some other language (C)
+does accept it.
+
+This also means that commands like
+@samp{g77 -fno-asm foo.f} yield no diagnostics,
+despite the fact that no phase of the command was
+able to recognize and process @samp{-fno-asm}---perhaps
+a warning about this would be helpful if it were
+possible.
+
+Code that processes Fortran options is found in
+@file{@value{path-g77}/top.c}, function @samp{ffe_decode_option}.
+This code needs to check positive and negative forms
+of each option.
+
+The defaults for Fortran options are set in their
+global definitions, also found in @file{@value{path-g77}/top.c}.
+Many of these defaults are actually macros defined
+in @file{@value{path-g77}/target.h}, since they might be
+machine-specific.
+However, since, in practice, GNU compilers
+should behave the same way on all configurations
+(especially when it comes to language constructs),
+the practice of setting defaults in @file{target.h}
+is likely to be deprecated and, ultimately, stopped
+in future versions of @code{g77}.
+
+Accessor macros for Fortran options, used by code
+in the @code{g77} FFE, are defined in @file{@value{path-g77}/top.h}.
+
+@emph{Compiler options} are listed in @file{gcc/toplev.c}
+in the array @samp{f_options}.
+An option not listed in @samp{lang_options} is
+looked up in @samp{f_options} and handled from there.
+
+The defaults for compiler options are set in the
+global definitions for the corresponding variables,
+some of which are in @file{gcc/toplev.c}.
+
+You can set different defaults for @emph{Fortran-oriented}
+or @emph{Fortran-reticent} compiler options by changing
+the way @code{f771} handles the @samp{-fset-g77-defaults}
+option, which is always provided as the first option when
+called by @code{g77} or @code{gcc}.
+
+This code is in @samp{ffe_decode_options} in @file{@value{path-g77}/top.c}.
+Have it change just the variables that you want to default
+to a different setting for Fortran compiles compared to
+compiles of other languages.
+
+The @samp{-fset-g77-defaults} option is passed to @code{f771}
+automatically because of the specification information
+kept in @file{@value{path-g77}/lang-specs.h}.
+This file tells the @code{gcc} command how to recognize,
+in this case, Fortran source files (those to be preprocessed,
+and those that are not), and further, how to invoke the
+appropriate programs (including @code{f771}) to process
+those source files.
+
+It is in @file{@value{path-g77}/lang-specs.h} that @samp{-fset-g77-defaults},
+@samp{-fversion}, and other options are passed, as appropriate,
+even when the user has not explicitly specified them.
+Other ``internal'' options such as @samp{-quiet} also
+are passed via this mechanism.

+
+Don't bother doing any performance analysis until most of the
+following items are taken care of, because there's no question
+they represent serious space/time problems, although some of
+them show up only given certain kinds of (popular) input.
+
+@itemize @bullet
+@item
+Improve @samp{malloc} package and its uses to specify more info about
+memory pools and, where feasible, use obstacks to implement them.
+
+@item
+Skip over uninitialized portions of aggregate areas (arrays,
+@code{COMMON} areas, @code{EQUIVALENCE} areas) so zeros need not be output.
+This would reduce memory usage for large initialized aggregate
+areas, even ones with only one initialized element.
+
+As of version 0.5.18, a portion of this item has already been
+accomplished.
+
+@item
+Prescan the statement (in @file{sta.c}) so that the nature of the statement
+is determined as much as possible by looking entirely at its form,
+and not looking at any context (previous statements, including types
+of symbols).
+This would allow ripping out of the statement-confirmation,
+symbol retraction/confirmation, and diagnostic inhibition
+mechanisms.
+Plus, it would result in much-improved diagnostics.
+For example, @samp{CALL some-intrinsic(@dots{})}, where the intrinsic
+is not a subroutine intrinsic, would result actual error instead of the
+unimplemented-statement catch-all.
+
+@item
+Throughout @code{g77}, don't pass line/column pairs where
+a simple @samp{ffewhere} type, which points to the error as much as is
+desired by the configuration, will do, and don't pass @samp{ffelexToken} types
+where a simple @samp{ffewhere} type will do.
+Then, allow new default
+configuration of @samp{ffewhere} such that the source line text is not
+preserved, and leave it to things like Emacs' next-error function
+to point to them (now that @samp{next-error} supports column,
+or, perhaps, character-offset, numbers).
+The change in calling sequences should improve performance somewhat,
+as should not having to save source lines.
+(Whether this whole
+item will improve performance is questionable, but it should
+improve maintainability.)
+
+@item
+Handle @samp{DATA (A(I),I=1,1000000)/1000000*2/} more efficiently, especially
+as regards the assembly output.
+Some of this might require improving
+the back end, but lots of improvement in space/time required in @code{g77}
+itself can be fairly easily obtained without touching the back end.
+Maybe type-conversion, where necessary, can be speeded up as well in
+cases like the one shown (converting the @samp{2} into @samp{2.}).
+
+@item
+If analysis shows it to be worthwhile, optimize @file{lex.c}.
+
+@item
+Consider redesigning @file{lex.c} to not need any feedback
+during tokenization, by keeping track of enough parse state on its

+@section Better Optimization
+@cindex optimization, better
+@cindex code generation, improving
+
+Much of this work should be put off until after @code{g77} has
+all the features necessary for its widespread acceptance as a
+useful F77 compiler.
+However, perhaps this work can be done in parallel during
+the feature-adding work.
+
+@itemize @bullet
+@item
+Do the equivalent of the trick of putting @samp{extern inline} in front
+of every function definition in @code{libg2c} and #include'ing the resulting
+file in @code{f2c}+@code{gcc}---that is, inline all run-time-library functions
+that are at all worth inlining.
+(Some of this has already been done, such as for integral exponentiation.)
+
+@item
+When doing @samp{CHAR_VAR = CHAR_FUNC(@dots{})},
+and it's clear that types line up
+and @samp{CHAR_VAR} is addressable or not a @samp{VAR_DECL},
+make @samp{CHAR_VAR}, not a
+temporary, be the receiver for @samp{CHAR_FUNC}.
+(This is now done for @code{COMPLEX} variables.)
+
+@item
+Design and implement Fortran-specific optimizations that don't
+really belong in the back end, or where the front end needs to
+give the back end more info than it currently does.
+
+@item
+Design and implement a new run-time library interface, with the
+code going into @code{libgcc} so no special linking is required to
+link Fortran programs using standard language features.
+This library
+would speed up lots of things, from I/O (using precompiled formats,
+doing just one, or, at most, very few, calls for arrays or array sections,
+and so on) to general computing (array/section implementations of
+various intrinsics, implementation of commonly performed loops that
+aren't likely to be optimally compiled otherwise, etc.).
+
+Among the important things the library would do are:
+
+@itemize @bullet
+@item
+Be a one-stop-shop-type
+library, hence shareable and usable by all, in that what are now
+library-build-time options in @code{libg2c} would be moved at least to the
+@code{g77} compile phase, if not to finer grains (such as choosing how
+list-directed I/O formatting is done by default at @code{OPEN} time, for
+preconnected units via options or even statements in the main program
+unit, maybe even on a per-I/O basis with appropriate pragma-like
+devices).
+@end itemize
+
+@item
+Probably requiring the new library design, change interface to
+normally have @code{COMPLEX} functions return their values in the way
+@code{gcc} would if they were declared @code{__complex__ float},
+rather than using
+the mechanism currently used by @code{CHARACTER} functions (whereby the
+functions are compiled as returning void and their first arg is
+a pointer to where to store the result).
+(Don't append underscores to
+external names for @code{COMPLEX} functions in some cases once @code{g77} uses
+@code{gcc} rather than @code{f2c} calling conventions.)
+
+@item
+Do something useful with @samp{doiter} references where possible.
+For example, @samp{CALL FOO(I)} cannot modify @samp{I} if within
+a @code{DO} loop that uses @samp{I} as the
+iteration variable, and the back end might find that info useful
+in determining whether it needs to read @samp{I} back into a register after
+the call.
+(It normally has to do that, unless it knows @samp{FOO} never
+modifies its passed-by-reference argument, which is rarely the case
+for Fortran-77 code.)

+
+Making @code{g77} easier to configure, port, build, and install, either
+as a single-system compiler or as a cross-compiler, would be
+very useful.
+
+@itemize @bullet
+@item
+A new library (replacing @code{libg2c}) should improve portability as well as
+produce more optimal code.
+Further, @code{g77} and the new library should
+conspire to simplify naming of externals, such as by removing unnecessarily
+added underscores, and to reduce/eliminate the possibility of naming
+conflicts, while making debugger more straightforward.
+
+Also, it should
+make multi-language applications more feasible, such as by providing
+Fortran intrinsics that get Fortran unit numbers given C @code{FILE *}
+descriptors.
+
+@item
+Possibly related to a new library, @code{g77} should produce the equivalent
+of a @code{gcc} @samp{main(argc, argv)} function when it compiles a
+main program unit, instead of compiling something that must be
+called by a library
+implementation of @code{main()}.
+
+This would do many useful things such as
+provide more flexibility in terms of setting up exception handling,
+not requiring programmers to start their debugging sessions with
+@kbd{breakpoint MAIN__} followed by @kbd{run}, and so on.
+
+@item
+The GBE needs to understand the difference between alignment
+requirements and desires.
+For example, on Intel x86 machines, @code{g77} currently imposes
+overly strict alignment requirements, due to the back end, but it
+would be useful for Fortran and C programmers to be able to override

+way.

+For example,
+anything a caller can check, semantically, let it do so, rather
+than having @file{expr.c} do it.
+(Exceptions might include things like

+and @file{ste.c}, and get rid of the @samp{opCONVERT(opANY)} kludge
+(after determining if there is indeed no real need for it).
+
+@item
+Utility to read and check @file{bad.def} messages and their references in the
+code, to make sure calls are consistent with message templates.
+
+@item
+Search and fix @samp{&ffe@dots{}} and similar so that
+@samp{ffe@dots{}ptr@dots{}} macros are
+available instead (a good argument for wishing this could have written all
+this stuff in C++, perhaps).
+On the other hand, it's questionable whether this sort of
+improvement is really necessary, given the availability of
+tools such as Emacs and Perl, which make finding any
+address-taking of structure members easy enough?
+
+@item
+Some modules truly export the member names of their structures (and the
+structures themselves), maybe fix this, and fix other modules that just
+appear to as well (by appending @samp{_}, though it'd be ugly and probably
+not worth the time).
+
+@item
+Implement C macros @samp{RETURNS(value)} and @samp{SETS(something,value)}
+in @file{proj.h}
+and use them throughout @code{g77} source code (especially in the definitions
+of access macros in @samp{.h} files) so they can be tailored
+to catch code writing into a @samp{RETURNS()} or reading from a @samp{SETS()}.
+
+@item
+Decorate throughout with @code{const} and other such stuff.
+
+@item
+All F90 notational derivations in the source code are still based
+on the S8.112 version of the draft standard.
+Probably should update
+to the official standard, or put documentation of the rules as used
+in the code@dots{}uh@dots{}in the code.
+
+@item
+Some @samp{ffebld_new} calls (those outside of @file{ffeexpr.c} or
+inside but invoked via paths not involving @samp{ffeexpr_lhs} or
+@samp{ffeexpr_rhs}) might be creating things

+Some @samp{ffebld_list_new} (or whatever) calls might not be matched by
+@samp{ffebld_list_bottom} (or whatever) calls, which might someday matter.
+(It definitely is not a problem just yet.)
+
+@item
+Probably not doing clean things when we fail to @code{EQUIVALENCE} something
+due to alignment/mismatch or other problems---they end up without
+@samp{ffestorag} objects, so maybe the backend (and other parts of the front
+end) can notice that and handle like an @samp{opANY} (do what it wants, just

+@smallexample
+Ambiguous use of intrinsic @var{intrinsic} @dots{}
+@end smallexample
+
+The type of the argument to the invocation of the @var{intrinsic}
+intrinsic is a @code{COMPLEX} type other than @code{COMPLEX(KIND=1)}.
+Typically, it is @code{COMPLEX(KIND=2)}, also known as
+@code{DOUBLE COMPLEX}.
+
+The interpretation of this invocation depends on the particular
+dialect of Fortran for which the code was written.
+Some dialects convert the real part of the argument to
+@code{REAL(KIND=1)}, thus losing precision; other dialects,
+and Fortran 90, do no such conversion.
+
+So, GNU Fortran rejects such invocations except under certain
+circumstances, to avoid making an incorrect assumption that results
+in generating the wrong code.
+
+To determine the dialect of the program unit, perhaps even whether
+that particular invocation is properly coded, determine how the
+result of the intrinsic is used.
+
+The result of @var{intrinsic} is expected (by the original programmer)
+to be @code{REAL(KIND=1)} (the non-Fortran-90 interpretation) if:
+
+@itemize @bullet
+@item
+It is passed as an argument to a procedure that explicitly or
+implicitly declares that argument @code{REAL(KIND=1)}.
+
+For example,
+a procedure with no @code{DOUBLE PRECISION} or @code{IMPLICIT DOUBLE PRECISION}
+statement specifying the dummy argument corresponding to an
+actual argument of @samp{REAL(Z)}, where @samp{Z} is declared
+@code{DOUBLE COMPLEX}, strongly suggests that the programmer
+expected @samp{REAL(Z)} to return @code{REAL(KIND=1)} instead
+of @code{REAL(KIND=2)}.
+
+@item
+It is used in a context that would otherwise not include
+any @code{REAL(KIND=2)} but where treating the @var{intrinsic}
+invocation as @code{REAL(KIND=2)} would result in unnecessary
+promotions and (typically) more expensive operations on the
+wider type.
+
+For example:
+
+@smallexample
+DOUBLE COMPLEX Z
+@dots{}
+R(1) = T * REAL(Z)
+@end smallexample
+
+The above example suggests the programmer expected the real part
+of @samp{Z} to be converted to @code{REAL(KIND=1)} before being
+multiplied by @samp{T} (presumed, along with @samp{R} above, to
+be type @code{REAL(KIND=1)}).
+
+Otherwise, the conversion would have to be delayed until after
+the multiplication, requiring not only an extra conversion
+(of @samp{T} to @code{REAL(KIND=2)}), but a (typically) more
+expensive multiplication (a double-precision multiplication instead
+of a single-precision one).
+@end itemize
+
+The result of @var{intrinsic} is expected (by the original programmer)
+to be @code{REAL(KIND=2)} (the Fortran 90 interpretation) if:
+
+@itemize @bullet
+@item
+It is passed as an argument to a procedure that explicitly or
+implicitly declares that argument @code{REAL(KIND=2)}.
+
+For example, a procedure specifying a @code{DOUBLE PRECISION}
+dummy argument corresponding to an
+actual argument of @samp{REAL(Z)}, where @samp{Z} is declared
+@code{DOUBLE COMPLEX}, strongly suggests that the programmer
+expected @samp{REAL(Z)} to return @code{REAL(KIND=2)} instead
+of @code{REAL(KIND=1)}.
+
+@item
+It is used in an expression context that includes
+other @code{REAL(KIND=2)} operands,
+or is assigned to a @code{REAL(KIND=2)} variable or array element.
+
+For example:
+
+@smallexample
+DOUBLE COMPLEX Z
+DOUBLE PRECISION R, T
+@dots{}
+R(1) = T * REAL(Z)
+@end smallexample
+
+The above example suggests the programmer expected the real part
+of @samp{Z} to @emph{not} be converted to @code{REAL(KIND=1)}
+by the @code{REAL()} intrinsic.
+
+Otherwise, the conversion would have to be immediately followed
+by a conversion back to @code{REAL(KIND=2)}, losing
+the original, full precision of the real part of @code{Z},
+before being multiplied by @samp{T}.
+@end itemize
+
+Once you have determined whether a particular invocation of @var{intrinsic}
+expects the Fortran 90 interpretation, you can:
+
+@itemize @bullet
+@item
+Change it to @samp{DBLE(@var{expr})} (if @var{intrinsic} is
+@samp{REAL}) or @samp{DIMAG(@var{expr})} (if @var{intrinsic}
+is @samp{AIMAG})
+if it expected the Fortran 90 interpretation.
+
+This assumes @var{expr} is @code{COMPLEX(KIND=2)}---if it is
+some other type, such as @code{COMPLEX*32}, you should use the
+appropriate intrinsic, such as the one to convert to @code{REAL*16}
+(perhaps @code{DBLEQ()} in place of @code{DBLE()}, and
+@code{QIMAG()} in place of @code{DIMAG()}).
+
+@item
+Change it to @samp{REAL(@var{intrinsic}(@var{expr}))},
+otherwise.
+This converts to @code{REAL(KIND=1)} in all working
+Fortran compilers.
+@end itemize
+
+If you don't want to change the code, and you are certain that all
+ambiguous invocations of @var{intrinsic} in the source file have
+the same expectation regarding interpretation, you can:
+
+@itemize @bullet
+@item
+Compile with the @code{g77} option @samp{-ff90}, to enable the
+Fortran 90 interpretation.
+
+@item
+Compile with the @code{g77} options @samp{-fno-f90 -fugly-complex},
+to enable the non-Fortran-90 interpretations.
+@end itemize
+
+@xref{REAL() and AIMAG() of Complex}, for more information on this
+issue.
+
+Note: If the above suggestions don't produce enough evidence
+as to whether a particular program expects the Fortran 90
+interpretation of this ambiguous invocation of @var{intrinsic},
+there is one more thing you can try.
+
+If you have access to most or all the compilers used on the
+program to create successfully tested and deployed executables,
+read the documentation for, and @emph{also} test out, each compiler
+to determine how it treats the @var{intrinsic} intrinsic in
+this case.
+(If all the compilers don't agree on an interpretation, there
+might be lurking bugs in the deployed versions of the program.)

+The @var{intrinsic} is explicitly declared in one program

+
+The name @var{intrinsic} is used for a global entity (a common
+block or a program unit) in one program unit and implicitly
+used as an intrinsic in another program unit.
+
+This diagnostic is designed to catch cases where a program
+intends to use a name entirely as a global name, but @code{g77}
+recognizes the name as an intrinsic in the program unit that
+references the name, a situation that would likely produce
+incorrect code.
+
+For example:
+
+@smallexample
+INTEGER FUNCTION TIME()
+@dots{}
+END
+@dots{}
+PROGRAM SAMP
+INTEGER TIME
+PRINT *, 'Time is ', TIME()
+END
+@end smallexample
+
+The above example defines a program unit named @samp{TIME}, but
+the reference to @samp{TIME} in the main program unit @samp{SAMP}
+is normally treated by @code{g77} as a reference to the intrinsic
+@code{TIME()} (unless a command-line option that prevents such
+treatment has been specified).
+
+As a result, the program @samp{SAMP} will @emph{not}
+invoke the @samp{TIME} function in the same source file.
+
+Since @code{g77} recognizes @code{libU77} procedures as
+intrinsics, and since some existing code uses the same names
+for its own procedures as used by some @code{libU77}
+procedures, this situation is expected to arise often enough
+to make this sort of warning worth issuing.
+
+After verifying that the program unit making implicit use
+of the intrinsic is indeed written expecting the intrinsic,
+add an @samp{INTRINSIC @var{intrinsic}} statement to that
+program unit to prevent this warning.
+
+Or, if you believe the program unit is designed to invoke the

+
+This and related warnings are disabled by using

+Although the diagnostics identify specific problems, they can
+be produced when general problems such as the following occur:
+
+@itemize @bullet
+@item
+The source file contains something other than Fortran code.
+
+If the code in the file does not look like many of the examples
+elsewhere in this document, it might not be Fortran code.
+(Note that Fortran code often is written in lower case letters,
+while the examples in this document use upper case letters,
+for stylistic reasons.)
+
+For example, if the file contains lots of strange-looking
+characters, it might be APL source code; if it contains lots
+of parentheses, it might be Lisp source code; if it
+contains lots of bugs, it might be C++ source code.
+
+@item
+The source file contains free-form Fortran code, but @samp{-ffree-form}
+was not specified on the command line to compile it.
+
+Free form is a newer form for Fortran code.
+The older, classic form is called fixed form.
+
+Fixed-form code is visually fairly distinctive, because
+numerical labels and comments are all that appear in
+the first five columns of a line, the sixth column is
+reserved to denote continuation lines,
+and actual statements start at or beyond column 7.
+Spaces generally are not significant, so if you
+see statements such as @samp{REALX,Y} and @samp{DO10I=1,100},
+you are looking at fixed-form code.
+Comment lines are indicated by the letter @samp{C} or the symbol
+@samp{*} in column 1.
+(Some code uses @samp{!} or @samp{/*} to begin in-line comments,
+which many compilers support.)
+
+Free-form code is distinguished from fixed-form source
+primarily by the fact that statements may start anywhere.
+(If lots of statements start in columns 1 through 6,
+that's a strong indicator of free-form source.)
+Consecutive keywords must be separated by spaces, so
+@samp{REALX,Y} is not valid, while @samp{REAL X,Y} is.
+There are no comment lines per se, but @samp{!} starts a
+comment anywhere in a line (other than within a character or
+Hollerith constant).
+
+@xref{Source Form}, for more information.
+
+@item
+The source file is in fixed form and has been edited without
+sensitivity to the column requirements.
+
+Statements in fixed-form code must be entirely contained within
+columns 7 through 72 on a given line.
+Starting them ``early'' is more likely to result in diagnostics
+than finishing them ``late'', though both kinds of errors are
+often caught at compile time.
+
+For example, if the following code fragment is edited by following
+the commented instructions literally, the result, shown afterward,
+would produce a diagnostic when compiled:
+
+@smallexample
+C On XYZZY systems, remove "C" on next line:
+C     CALL XYZZY_RESET
+@end smallexample
+
+The result of editing the above line might be:
+
+@smallexample
+C On XYZZY systems, remove "C" on next line:
+     CALL XYZZY_RESET
+@end smallexample
+
+However, that leaves the first @samp{C} in the @samp{CALL}
+statement in column 6, making it a comment line, which is
+not really what the author intended, and which is likely
+to result in one of the above-listed diagnostics.
+
+@emph{Replacing} the @samp{C} in column 1 with a space
+is the proper change to make, to ensure the @samp{CALL}
+keyword starts in or after column 7.
+
+Another common mistake like this is to forget that fixed-form
+source lines are significant through only column 72, and that,
+normally, any text beyond column 72 is ignored or is diagnosed
+at compile time.
+
+@xref{Source Form}, for more information.

+The source file requires preprocessing, and the preprocessing
+is not being specified at compile time.
+
+A source file containing lines beginning with @code{#define},

+requires preprocessing.
+
+If the file's suffix is @samp{.f} or @samp{.for}, the file
+will normally be compiled @emph{without} preprocessing by @code{g77}.
+
+Change the file's suffix from @samp{.f} to @samp{.F} (or, on

+Global name @var{name} defined at @dots{} already defined@dots{}
+Global name @var{name} at @dots{} has different type@dots{}
+Too many arguments passed to @var{name} at @dots{}
+Too few arguments passed to @var{name} at @dots{}
+Argument #@var{n} of @var{name} is @dots{}
+@end smallexample
+
+These messages all identify disagreements about the
+global procedure named @var{name} among different program
+units (usually including @var{name} itself).
+
+These disagreements, if not diagnosed, could result in a
+compiler crash if the compiler attempted to inline a reference
+to @var{name} within a calling program unit that disagreed
+with the @var{name} program unit regarding whether the
+procedure is a subroutine or function, the type of the
+return value of the procedure (if it is a function), the
+number of arguments the procedure accepts, or the type
+of each argument.
+
+Such disagreements @emph{should} be fixed in the Fortran
+code itself.
+However, if that is not immediately practical, and the code
+has been working for some time, it is possible it will work
+when compiled by @code{g77} with the @samp{-fno-globals} option.
+
+The @samp{-fno-globals} option disables these diagnostics, and
+also disables all inlining of references to global procedures
+to avoid compiler crashes.
+The diagnostics are actually produced, but as warnings, unless
+the @samp{-Wno-globals} option also is specified.
+
+After using @samp{-fno-globals} to work around these problems,
+it is wise to stop using that option and address them by fixing
+the Fortran code, because such problems, while they might not
+actually result in bugs on some systems, indicate that the code
+is not as portable as it could be.
+In particular, the code might appear to work on a particular
+system, but have bugs that affect the reliability of the data
+without exhibiting any other outward manifestations of the bugs.

+@xref{Missing strtoul or bsearch}, for more information on

+which occurs only in releases of @code{g77}
+based on @code{gcc}.
+(It does not occur in @code{egcs}.)
+
+On AIX 4.1, @code{g77} might not build with the native (non-GNU) tools
+due to a linker bug in coping with the @samp{-bbigtoc} option which
+leads to a @samp{Relocation overflow} error.  The GNU linker is not
+recommended on current AIX versions, though; it was developed under a
+now-unsupported version.  This bug is said to be fixed by `update PTF
+U455193 for APAR IX75823'.
+
+Compiling with @samp{-mminimal-toc}
+might solve this problem, e.g.@: by adding
+@smallexample
+BOOT_CFLAGS='-mminimal-toc -O2 -g'
+@end smallexample

+/* This file contains a filter for the main `gcc' driver, which is
+   replicated for the `g77' driver by adding this filter.  The purpose
+   of this filter is to be basically identical to gcc (in that
+   it faithfully passes all of the original arguments to gcc) but,
+   unless explicitly overridden by the user in certain ways, ensure
+   that the needs of the language supported by this wrapper are met.
+
+   For GNU Fortran (g77), we do the following to the argument list
+   before passing it to `gcc':
+
+   1.  Make sure `-lg2c -lm' is at the end of the list.
+
+   2.  Make sure each time `-lg2c' or `-lm' is seen, it forms
+       part of the series `-lg2c -lm'.
+
+   #1 and #2 are not done if `-nostdlib' or any option that disables
+   the linking phase is present, or if `-xfoo' is in effect.  Note that
+   a lack of source files or -l options disables linking.
+
+   This program was originally made out of gcc/cp/g++spec.c, but the
+   way it builds the new argument list was rewritten so it is much
+   easier to maintain, improve the way it decides to add or not add
+   extra arguments, etc.  And several improvements were made in the
+   handling of arguments, primarily to make it more consistent with
+   `gcc' itself.  */

+   Description:
+      Manages information kept across individual program units within a single
+      source file.  This includes reporting errors when a name is defined
+      multiple times (for example, two program units named FOO) and when a
+      COMMON block is given initial data in more than one program unit.

+/* This is the file containing the verbage for the
+   intrinsics.  It consists of a data base built up
+   via DEFDOC macros of the form:
+
+   DEFDOC (IMP, SUMMARY, DESCRIPTION)
+
+   IMP is the implementation keyword used in the intrin module.
+   SUMMARY is the short summary to go in the "* Menu:" section
+   of the Info document.  DESCRIPTION is the longer description
+   to go in the documentation itself.
+
+   Note that IMP is leveraged across multiple intrinsic names.
+
+   To make for more accurate and consistent documentation,
+   the translation made by intdoc.c of the text in SUMMARY
+   and DESCRIPTION includes the special sequence
+
+   @ARGNO@
+
+   where ARGNO is a series of digits forming a number that
+   is substituted by intdoc.c as follows:
+
+   0     The initial-caps form of the intrinsic name (e.g. Float).
+   1-98  The initial-caps form of the ARGNO'th argument.
+   99    (SUMMARY only) a newline plus the appropriate # of spaces.
+
+   Hope this info is enough to encourage people to feel free to
+   add documentation to this file!

+result.
+Still, @code{DCMPLX()} converts even @code{REAL*16} arguments

+construction of arbitrary-precision values without

+     message is printed.  Any remaining text on the line is passed to the
+     parser tasks, thus even an all-blank line (possibly with an ignored
+     label) aside from a positive continuation character might have meaning
+     in the midst of a character or hollerith constant.
+
+     2. If a line has no explicit continuation character (that is, it has a
+     space in column 6 and the first non-space character past column 6 is
+     not a digit 0-9), then there are two possibilities:
+
+     A. A label is present and/or a non-space (and non-comment) character
+     appears somewhere after column 6.	Terminate processing of the previous
+     statement, if any, send the new label for the next statement, if any,
+     and start processing a new statement with this non-blank character, if
+     any.
+
+     B. The line is essentially blank, except for a possible comment character.
+     Don't terminate processing of the previous statement and don't pass any
+     characters to the parser tasks, since the line is not flagged as a
+     continuation line.	 We treat it just like a completely blank line.
+
+     3. If a line has a continuation character of zero (0), then we terminate
+     processing of the previous statement, if any, send the new label for the
+     next statement, if any, and start processing a new statement, if any
+     non-blank characters are present.
+
+     If, when checking to see if we should terminate the previous statement, it
+     is found that there is no previous statement but that there is an

+   separate tokens for analysis (whereas in fixed-form the spaces are
+   ignored resulting in one long token).  But in FORMAT statements, for
+   some reason, the Fortran 90 standard specifies that spaces can occur
+   anywhere within a format-item-list with no effect on the format spec
+   (except of course within character string edit descriptors), which means
+   that "1PE14.2" and "1 P E 1 4 . 2" are equivalent.  For the FORMAT
+   statement handling, the existence of spaces makes it hard to deal with,
+   because each token is seen distinctly (i.e. seven tokens in the latter
+   example).  But when no spaces are provided, as in the former example,
+   then only four tokens are generated, NUMBER("1"), NAME("PE14"), PERIOD,
+   NUMBER ("2").  By generating a NAMES instead of NAME, three things happen:
+   One, ffest_kw_format_ does a substring rather than full-string match,
+   and thus matches "PE14" to "PE"; two, ffelex_token_xyz_from_names functions
+   may be used to pull NAME/NAMES and NUMBER tokens out of the NAMES token;
+   and three, error reporting can point to the actual character rather than
+   at or prior to it.  The first two things could be resolved by providing
+   alternate functions fairly easy, thus allowing FORMAT handling to expect
+   both lexers to generate NAME tokens instead of NAMES (with otherwise minor
+   changes to FORMAT parsing), but the third, error reporting, would suffer,
+   and when one makes mistakes in a FORMAT, believe me, one wants a pointer
+   to exactly where the compilers thinks the problem is, to even begin to get
+   a handle on it.  So there.  */

+@cindex versions, recent
+@cindex recent versions
+
+Changes made to recent versions of GNU Fortran are listed
+below, with the most recent version first.
+
+The changes are generally listed in order:
+
+@enumerate
+@item
+Code-generation and run-time-library bug-fixes
+
+@item
+Compiler and run-time-library crashes involving valid code
+that have been fixed
+
+@item
+New features
+
+@item
+Fixes and enhancements to existing features
+
+@item
+New diagnostics
+
+@item
+Internal improvements
+
+@item
+Miscellany
+@end enumerate
+
+This order is not strict---for example, some items
+involve a combination of these elements.
+
+Note that two variants of @code{g77} are tracked below.
+The @code{egcs} variant is described vis-a-vis
+previous versions of @code{egcs} and/or
+an official FSF version,
+as appropriate.
+
+Therefore, @code{egcs} versions sometimes have multiple listings
+to help clarify how they differ from other versions,
+though this can make getting a complete picture
+of what a particular @code{egcs} version contains
+somewhat more difficult.
+
+An online, ``live'' version of this document
+(derived directly from the up-to-date mainline version
+of @code{g77} within @code{egcs})
+is available at
+@uref{http://egcs.cygnus.com/onlinedocs/g77_news.html}.
+
+@heading In 0.5.24 and @code{egcs} 1.1.2 (versus 0.5.23 and 1.1.1):
+@itemize @bullet
+@item
+Fix the @code{IDate} Intrinsic (VXT)
+so the returned year is in the documented, non-Y2K-compliant range
+of 0--99,
+instead of being returned as 100 in the year 2000.
+
+@item
+Fix the @samp{Date_and_Time} intrinsic (in @code{libg2c})
+to return the milliseconds value properly
+in @var{Values}(8).
+
+@item
+Fix the @samp{LStat} intrinsic (in @code{libg2c})
+to return device-ID information properly
+in @var{SArray}(7).
+
+@item
+Improve documentation.
+@end itemize
+
+@heading In 0.5.24 and @code{egcs} 1.1.1 (versus 0.5.23 and 1.1):
+@itemize @bullet
+@item
+Fix @code{libg2c} so it performs an implicit @code{ENDFILE} operation
+(as appropriate)
+whenever a @code{REWIND} is done.
+
+(This bug was introduced in 0.5.23 and @code{egcs} 1.1 in
+@code{g77}'s version of @code{libf2c}.)
+
+@item
+Fix @code{libg2c} so it no longer crashes with a spurious diagnostic
+upon doing any I/O following a direct formatted write.
+
+(This bug was introduced in 0.5.23 and @code{egcs} 1.1 in
+@code{g77}'s version of @code{libf2c}.)
+
+@item
+Fix @code{g77} so it no longer crashes compiling references
+to the @samp{Rand} intrinsic on some systems.
+
+@item
+Fix @code{g77} portion of installation process so it works
+better on some systems
+(those with shells requiring @samp{else true} clauses
+on @samp{if} constructs
+for the completion code to be set properly).
+@end itemize
+
+@heading In @code{egcs} 1.1 (versus 0.5.24):
+@itemize @bullet
+@item
+Fix @code{g77} crash compiling code
+containing the construct @samp{CMPLX(0.)} or similar.
+
+@item
+Fix @code{g77} crash
+(or apparently infinite run-time)
+when compiling certain complicated expressions
+involving @code{COMPLEX} arithmetic
+(especially multiplication).
+
+@cindex DNRM2
+@cindex stack, 387 coprocessor
+@cindex Intel x86
+@cindex -O2
+@item
+Fix a code-generation bug that afflicted
+Intel x86 targets when @samp{-O2} was specified
+compiling, for example, an old version of
+the @samp{DNRM2} routine.
+
+The x87 coprocessor stack was being
+mismanaged in cases involving assigned @code{GOTO}
+and @code{ASSIGN}.
+
+@cindex alignment
+@cindex double-precision performance
+@cindex -malign-double
+@item
+Align static double-precision variables and arrays
+on Intel x86 targets
+regardless of whether @samp{-malign-double} is specified.
+
+Generally, this affects only local variables and arrays
+having the @code{SAVE} attribute
+or given initial values via @code{DATA}.
+@end itemize
+
+@c 1998-09-01: egcs-1.1 released.
+@heading In @code{egcs} 1.1 (versus @code{egcs} 1.0.3):
+@itemize @bullet
+@item
+Fix bugs in the @code{libU77} intrinsic @samp{HostNm}
+that wrote one byte beyond the end of its @samp{CHARACTER}
+argument,
+and in the @code{libU77} intrinsics
+@samp{GMTime} and @samp{LTime}
+that overwrote their arguments.
+
+@item
+Assumed arrays with negative bounds
+(such as @samp{REAL A(-1:*)})
+no longer elicit spurious diagnostics from @code{g77},
+even on systems with pointers having
+different sizes than integers.
+
+This bug is not known to have existed in any
+recent version of @code{gcc}.
+It was introduced in an early release of @code{egcs}.
+
+@item
+Valid combinations of @code{EXTERNAL},
+passing that external as a dummy argument
+without explicitly giving it a type,
+and, in a subsequent program unit,
+referencing that external as
+an external function with a different type
+no longer crash @code{g77}.
+
+@item
+@code{CASE DEFAULT} no longer crashes @code{g77}.
+
+@item
+The @samp{-Wunused} option no longer issues a spurious
+warning about the ``master'' procedure generated by
+@code{g77} for procedures containing @code{ENTRY} statements.
+
+@item
+Support @samp{FORMAT(I<@var{expr}>)} when @var{expr} is a
+compile-time constant @code{INTEGER} expression.
+
+@item
+Fix @code{g77} @samp{-g} option so procedures that
+use @samp{ENTRY} can be stepped through, line by line,
+in @code{gdb}.
+
+@item
+Allow any @code{REAL} argument to intrinsics
+@code{Second} and @code{CPU_Time}.
+
+@item
+Use @code{tempnam}, if available, to open scratch files
+(as in @samp{OPEN(STATUS='SCRATCH')})
+so that the @code{TMPDIR} environment variable,
+if present, is used.
+
+@item
+@code{g77}'s version of @code{libf2c} separates out
+the setting of global state
+(such as command-line arguments and signal handling)
+from @file{main.o} into distinct, new library
+archive members.
+
+This should make it easier to write portable applications
+that have their own (non-Fortran) @code{main()} routine
+properly set up the @code{libf2c} environment, even
+when @code{libf2c} (now @code{libg2c}) is a shared library.
+
+@item
+@code{g77} no longer installs the @file{f77} command
+and @file{f77.1} man page
+in the @file{/usr} or @file{/usr/local} heirarchy,
+even if the @file{f77-install-ok} file exists
+in the source or build directory.
+See the installation documentation for more information.
+
+@item
+@code{g77} no longer installs the @file{libf2c.a} library
+and @file{f2c.h} include file
+in the @file{/usr} or @file{/usr/local} heirarchy,
+even if the @file{f2c-install-ok} or @file{f2c-exists-ok} files exist
+in the source or build directory.
+See the installation documentation for more information.
+
+@item
+The @file{libf2c.a} library produced by @code{g77} has been
+renamed to @file{libg2c.a}.
+It is installed only in the @code{gcc} ``private''
+directory heirarchy, @file{gcc-lib}.
+This allows system administrators and users to choose which
+version of the @code{libf2c} library from @code{netlib} they
+wish to use on a case-by-case basis.
+See the installation documentation for more information.
+
+@item
+The @file{f2c.h} include (header) file produced by @code{g77}
+has been renamed to @file{g2c.h}.
+It is installed only in the @code{gcc} ``private''
+directory heirarchy, @file{gcc-lib}.
+This allows system administrators and users to choose which
+version of the include file from @code{netlib} they
+wish to use on a case-by-case basis.
+See the installation documentation for more information.
+
+@item
+The @code{g77} command now expects the run-time library
+to be named @code{libg2c.a} instead of @code{libf2c.a},
+to ensure that a version other than the one built and
+installed as part of the same @code{g77} version is picked up.
+
+@item
+During the configuration and build process,
+@code{g77} creates subdirectories it needs only as it
+needs them.
+Other cleaning up of the configuration and build process
+has been performed as well.
+
+@item
+@code{install-info} now used to update the directory of
+Info documentation to contain an entry for @code{g77}
+(during installation).
+
+@item
+Some diagnostics have been changed from warnings to errors,
+to prevent inadvertent use of the resulting, probably buggy,
+programs.
+These mostly include diagnostics about use of unsupported features
+in the @code{OPEN}, @code{INQUIRE}, @code{READ}, and
+@code{WRITE} statements,
+and about truncations of various sorts of constants.
+
+@item
+Improve compilation of @code{FORMAT} expressions so that
+a null byte is appended to the last operand if it
+is a constant.
+This provides a cleaner run-time diagnostic as provided
+by @code{libf2c} for statements like @samp{PRINT '(I1', 42}.
+
+@item
+Improve documentation and indexing.
+
+@item
+The upgrade to @code{libf2c} as of 1998-06-18
+should fix a variety of problems, including
+those involving some uses of the @samp{T} format
+specifier, and perhaps some build (porting) problems
+as well.
+@end itemize
+
+@heading In 0.5.24 and @code{egcs} 1.1 (versus 0.5.23):
+@itemize @bullet
+@item
+@code{g77} no longer produces incorrect code
+and initial values
+for @samp{EQUIVALENCE} and @samp{COMMON}
+aggregates that, due to ``unnatural'' ordering of members
+vis-a-vis their types, require initial padding.
+
+@item
+@code{g77} no longer crashes when compiling code
+containing specification statements such as
+@samp{INTEGER(KIND=7) PTR}.
+
+@item
+@code{g77} no longer crashes when compiling code
+such as @samp{J = SIGNAL(1, 2)}.
+
+@item
+@code{g77} now treats @samp{%LOC(@var{expr})} and
+@samp{LOC(@var{expr})} as ``ordinary'' expressions
+when they are used as arguments in procedure calls.
+This change applies only to global (filewide) analysis,
+making it consistent with
+how @code{g77} actually generates code
+for these cases.
+
+Previously, @code{g77} treated these expressions
+as denoting special ``pointer'' arguments
+for the purposes of filewide analysis.
+
+@item
+The @code{g77} driver now ensures that @samp{-lg2c}
+is specified in the link phase prior to any
+occurrence of @samp{-lm}.
+This prevents accidentally linking to a routine
+in the SunOS4 @samp{-lm} library
+when the generated code wants to link to the one
+in @code{libf2c} (@code{libg2c}).
+
+@item
+@code{g77} emits more debugging information when
+@samp{-g} is used.
+
+This new information allows, for example,
+@kbd{which __g77_length_a} to be used in @code{gdb}
+to determine the type of the phantom length argument
+supplied with @samp{CHARACTER} variables.
+
+This information pertains to internally-generated
+type, variable, and other information,
+not to the longstanding deficiencies vis-a-vis
+@samp{COMMON} and @samp{EQUIVALENCE}.
+
+@item
+The F90 @samp{Date_and_Time} intrinsic now is
+supported.
+
+@item
+The F90 @samp{System_Clock} intrinsic allows
+the optional arguments (except for the @samp{Count}
+argument) to be omitted.
+
+@item
+Upgrade to @code{libf2c} as of 1998-06-18.
+
+@item
+Improve documentation and indexing.
+@end itemize
+
+@c 1998-05-20: 0.5.23 released.
+@heading In 0.5.23 (versus 0.5.22):
+@itemize @bullet
+@item
+This release contains several regressions against
+version 0.5.22 of @code{g77}, due to using the
+``vanilla'' @code{gcc} back end instead of patching
+it to fix a few bugs and improve performance in a
+few cases.
+
+@ifset last-up-date
+@xref{Actual Bugs,,Actual Bugs We Haven't Fixed Yet},
+for information on the known bugs in this version,
+including the regressions.
+@end ifset
+
+@ifset NEWSONLY
+See @file{egcs/gcc/f/BUGS},
+for information on the known bugs in this version,
+including the regressions.
+@end ifset
+
+Features that have been dropped from this version
+of @code{g77} due to their being implemented
+via @code{g77}-specific patches to the @code{gcc}
+back end in previous releases include:
+
+@itemize --
+@item
+Support for @code{__restrict__} keyword,
+the options @samp{-fargument-alias}, @samp{-fargument-noalias},
+and @samp{-fargument-noalias-global},
+and the corresponding alias-analysis code.
+
+(@code{egcs} has the alias-analysis
+code, but not the @code{__restrict__} keyword.
+@code{egcs} @code{g77} users benefit from the alias-analysis
+code despite the lack of the @code{__restrict__} keyword,
+which is a C-language construct.)
+
+@item
+Support for the GNU compiler options
+@samp{-fmove-all-movables},
+@samp{-freduce-all-givs},
+and @samp{-frerun-loop-opt}.
+
+(@code{egcs} supports these options.
+@code{g77} users of @code{egcs} benefit from them even if
+they are not explicitly specified,
+because the defaults are optimized for @code{g77} users.)
+
+@item
+Support for the @samp{-W} option warning about
+integer division by zero.
+
+@item
+The Intel x86-specific option @samp{-malign-double}
+applying to stack-allocated data
+as well as statically-allocate data.
+@end itemize
+
+Note that the @file{gcc/f/gbe/} subdirectory has been removed
+from this distribution as a result of @code{g77} no longer
+including patches for the @code{gcc} back end.
+
+@item
+Fix bugs in the @code{libU77} intrinsic @samp{HostNm}
+that wrote one byte beyond the end of its @samp{CHARACTER}
+argument,
+and in the @code{libU77} intrinsics
+@samp{GMTime} and @samp{LTime}
+that overwrote their arguments.
+
+@item
+Support @code{gcc} version 2.8,
+and remove support for prior versions of @code{gcc}.
+
+@cindex -@w{}-driver option
+@cindex g77 options, -@w{}-driver
+@cindex options, -@w{}-driver
+@item
+Remove support for the @samp{--driver} option,
+as @code{g77} now does all the driving,
+just like @code{gcc}.
+
+@item
+@code{CASE DEFAULT} no longer crashes @code{g77}.
+
+@item
+Valid combinations of @code{EXTERNAL},
+passing that external as a dummy argument
+without explicitly giving it a type,
+and, in a subsequent program unit,
+referencing that external as

+no longer crash @code{g77}.

+even if the @file{f77-install-ok} file exists
+in the source or build directory.
+See the installation documentation for more information.

+@code{g77} no longer installs the @file{libf2c.a} library
+and @file{f2c.h} include file

+@heading In 0.5.21:
+@itemize @bullet
+@item
+Fix a code-generation bug introduced by 0.5.20
+caused by loop unrolling (by specifying
+@samp{-funroll-loops} or similar).
+This bug afflicted all code compiled by
+version 2.7.2.2.f.2 of @code{gcc} (C, C++,
+Fortran, and so on).
+
+@item
+Fix a code-generation bug manifested when
+combining local @code{EQUIVALENCE} with a
+@code{DATA} statement that follows
+the first executable statement (or is
+treated as an executable-context statement
+as a result of using the @samp{-fpedantic}
+option).
+
+@item
+Fix a compiler crash that occured when an
+integer division by a constant zero is detected.
+Instead, when the @samp{-W} option is specified,
+the @code{gcc} back end issues a warning about such a case.
+This bug afflicted all code compiled by
+version 2.7.2.2.f.2 of @code{gcc} (C, C++,
+Fortran, and so on).
+
+@item
+Fix a compiler crash that occurred in some cases
+of procedure inlining.
+(Such cases became more frequent in 0.5.20.)
+
+@item
+Fix a compiler crash resulting from using @code{DATA}
+or similar to initialize a @code{COMPLEX} variable or
+array to zero.
+
+@item
+Fix compiler crashes involving use of @code{AND}, @code{OR},
+or @code{XOR} intrinsics.
+
+@item
+Fix compiler bug triggered when using a @code{COMMON}
+or @code{EQUIVALENCE} variable
+as the target of an @code{ASSIGN}
+or assigned-@code{GOTO} statement.
+
+@item
+Fix compiler crashes due to using the name of a some
+non-standard intrinsics (such as @samp{FTELL} or
+@samp{FPUTC}) as such and as the name of a procedure
+or common block.
+Such dual use of a name in a program is allowed by
+the standard.
+
+@c @code{g77}'s version of @code{libf2c} has been modified
+@c so that the external names of library's procedures do not
+@c conflict with names used for Fortran procedures compiled
+@c by @code{g77}.
+@c An additional layer of jacket procedures has been added
+@c to @code{libf2c} to map the old names to the new names,
+@c for automatic use by programs that interface to the
+@c library procedures via the external-procedure mechanism.
+@c 
+@c For example, the intrinsic @code{FPUTC} previously was
+@c implemented by @code{g77} as a call to the @code{libf2c}
+@c routine @samp{fputc_}.
+@c This would conflict with a Fortran procedure named @code{FPUTC}
+@c (using default compiler options), and this conflict
+@c would cause a crash under certain circumstances.
+@c 
+@c Now, the intrinsic @code{FPUTC} calls @samp{G77_fputc_0},
+@c which does not conflict with the @samp{fputc_} external
+@c that implements a Fortran procedure named @code{FPUTC}.
+@c 
+@c Programs that refer to @code{FPUTC} as an external procedure
+@c without supplying their own implementation will link to
+@c the new @code{libf2c} routine @samp{fputc_}, which is
+@c simply a jacket routine that calls @samp{G77_fputc_0}.
+
+@item
+Place automatic arrays on the stack, even if
+@code{SAVE} or the @samp{-fno-automatic} option
+is in effect.
+This avoids a compiler crash in some cases.
+
+@item
+The @samp{-malign-double} option now reliably aligns
+@code{DOUBLE PRECISION} optimally on Pentium and
+Pentium Pro architectures (586 and 686 in @code{gcc}).
+
+@item
+New option @samp{-Wno-globals} disables warnings
+about ``suspicious'' use of a name both as a global
+name and as the implicit name of an intrinsic, and
+warnings about disagreements over the number or natures of
+arguments passed to global procedures, or the
+natures of the procedures themselves.
+
+The default is to issue such warnings, which are
+new as of this version of @code{g77}.
+
+@item
+New option @samp{-fno-globals} disables diagnostics
+about potentially fatal disagreements
+analysis problems, such as disagreements over the
+number or natures of arguments passed to global
+procedures, or the natures of those procedures themselves.
+
+The default is to issue such diagnostics and flag
+the compilation as unsuccessful.
+With this option, the diagnostics are issued as
+warnings, or, if @samp{-Wno-globals} is specified,
+are not issued at all.
+
+This option also disables inlining of global procedures,
+to avoid compiler crashes resulting from coding errors
+that these diagnostics normally would identify.
+
+@item
+Diagnose cases where a reference to a procedure
+disagrees with the type of that procedure, or
+where disagreements about the number or nature
+of arguments exist.
+This avoids a compiler crash.
+
+@item
+Fix parsing bug whereby @code{g77} rejected a
+second initialization specification immediately
+following the first's closing @samp{/} without
+an intervening comma in a @code{DATA} statement,
+and the second specification was an implied-DO list.
+
+@item
+Improve performance of the @code{gcc} back end so
+certain complicated expressions involving @code{COMPLEX}
+arithmetic (especially multiplication) don't appear to
+take forever to compile.
+
+@item
+Fix a couple of profiling-related bugs in @code{gcc}
+back end.
+
+@item
+Integrate GNU Ada's (GNAT's) changes to the back end,
+which consist almost entirely of bug fixes.
+These fixes are circa version 3.10p of GNAT.
+
+@item
+Include some other @code{gcc} fixes that seem useful in
+@code{g77}'s version of @code{gcc}.
+(See @file{gcc/ChangeLog} for details---compare it
+to that file in the vanilla @code{gcc-2.7.2.3.tar.gz}
+distribution.)
+
+@item
+Fix @code{libU77} routines that accept file and other names
+to strip trailing blanks from them, for consistency
+with other implementations.
+Blanks may be forcibly appended to such names by
+appending a single null character (@samp{CHAR(0)})
+to the significant trailing blanks.
+
+@item
+Fix @code{CHMOD} intrinsic to work with file names
+that have embedded blanks, commas, and so on.
+
+@item
+Fix @code{SIGNAL} intrinsic so it accepts an
+optional third @samp{Status} argument.
+
+@item
+Fix @code{IDATE()} intrinsic subroutine (VXT form)
+so it accepts arguments in the correct order.
+Documentation fixed accordingly, and for
+@code{GMTIME()} and @code{LTIME()} as well.
+
+@item
+Make many changes to @code{libU77} intrinsics to
+support existing code more directly.
+
+Such changes include allowing both subroutine and
+function forms of many routines, changing @code{MCLOCK()}
+and @code{TIME()} to return @code{INTEGER(KIND=1)} values,
+introducing @code{MCLOCK8()} and @code{TIME8()} to
+return @code{INTEGER(KIND=2)} values,
+and placing functions that are intended to perform
+side effects in a new intrinsic group, @code{badu77}.
+
+@item
+Improve @code{libU77} so it is more portable.
+
+@item
+Add options @samp{-fbadu77-intrinsics-delete},
+@samp{-fbadu77-intrinsics-hide}, and so on.
+
+@item
+Fix crashes involving diagnosed or invalid code.
+
+@item
+@code{g77} and @code{gcc} now do a somewhat better
+job detecting and diagnosing arrays that are too
+large to handle before these cause diagnostics
+during the assembler or linker phase, a compiler
+crash, or generation of incorrect code.
+
+@item
+Make some fixes to alias analysis code.
+
+@item
+Add support for @code{restrict} keyword in @code{gcc}
+front end.
+
+@item
+Support @code{gcc} version 2.7.2.3
+(modified by @code{g77} into version 2.7.2.3.f.1),
+and remove
+support for prior versions of @code{gcc}.
+
+@item
+Incorporate GNAT's patches to the @code{gcc} back
+end into @code{g77}'s, so GNAT users do not need
+to apply GNAT's patches to build both GNAT and @code{g77}
+from the same source tree.
+
+@item
+Modify @code{make} rules and related code so that
+generation of Info documentation doesn't require
+compilation using @code{gcc}.
+Now, any ANSI C compiler should be adequate to
+produce the @code{g77} documentation (in particular,
+the tables of intrinsics) from scratch.

+
+@item
+Support @samp{*f771} entry in @code{gcc} @file{specs} file.

+cross-compiling.
+
+@item
+Fix @code{libf2c} build procedure to re-archive library
+if previous attempt to archive was interrupted.
+
+@item
+Change @code{gcc} to unroll loops only during the last
+invocation (of as many as two invocations) of loop
+optimization.
+
+@item
+Improve handling of @samp{-fno-f2c} so that code that
+attempts to pass an intrinsic as an actual argument,
+such as @samp{CALL FOO(ABS)}, is rejected due to the fact
+that the run-time-library routine is, effectively,
+compiled with @samp{-ff2c} in effect.
+
+@item
+Fix @code{g77} driver to recognize @samp{-fsyntax-only}
+as an option that inhibits linking, just like @samp{-c} or
+@samp{-S}, and to recognize and properly handle the
+@samp{-nostdlib}, @samp{-M}, @samp{-MM}, @samp{-nodefaultlibs},
+and @samp{-Xlinker} options.
+
+@item
+Upgrade to @code{libf2c} as of 1997-08-16.
+
+@item
+Modify @code{libf2c} to consistently and clearly diagnose
+recursive I/O (at run time).
+
+@item
+@code{g77} driver now prints version information (such as produced
+by @kbd{g77 -v}) to @code{stderr} instead of @code{stdout}.
+
+@item
+The @samp{.r} suffix now designates a Ratfor source file,
+to be preprocessed via the @code{ratfor} command, available
+separately.
+
+@item
+Fix some aspects of how @code{gcc} determines what kind of
+system is being configured and what kinds are supported.
+For example, GNU Linux/Alpha ELF systems now are directly
+supported.
+
+@item
+Improve diagnostics.
+
+@item
+Improve documentation and indexing.
+
+@item
+Include all pertinent files for @code{libf2c} that come
+from @code{netlib.bell-labs.com}; give any such files
+that aren't quite accurate in @code{g77}'s version of
+@code{libf2c} the suffix @samp{.netlib}.

+The @samp{-fno-typeless-boz} option is now the default.
+
+This option specifies that non-decimal-radix
+constants using the prefixed-radix form (such as @samp{Z'1234'})
+are to be interpreted as @code{INTEGER} constants.
+Specify @samp{-ftypeless-boz} to cause such
+constants to be interpreted as typeless.

+(Version 0.5.19 introduced @samp{-fno-typeless-boz} and
+its inverse.)
+
+@item
+Options @samp{-ff90-intrinsics-enable} and
+@samp{-fvxt-intrinsics-enable} now are the
+defaults.
+
+Some programs might use names that clash with
+intrinsic names defined (and now enabled) by these
+options or by the new @code{libU77} intrinsics.
+Users of such programs might need to compile them
+differently (using, for example, @samp{-ff90-intrinsics-disable})
+or, better yet, insert appropriate @code{EXTERNAL}
+statements specifying that these names are not intended
+to be names of intrinsics.
+
+@item
+The @samp{ALWAYS_FLUSH} macro is no longer defined when
+building @code{libf2c}, which should result in improved
+I/O performance, especially over NFS.
+
+@emph{Note:} If you have code that depends on the behavior
+of @code{libf2c} when built with @samp{ALWAYS_FLUSH} defined,
+you will have to modify @code{libf2c} accordingly before
+building it from this and future versions of @code{g77}.
+
+@item
+Dave Love's implementation of @code{libU77} has been
+added to the version of @code{libf2c} distributed with

+
+@item
+The @samp{-fvxt-not-f90} option has been deleted,

+
+@item
+Related to supporting Alpha (AXP) machines, the @code{LOC()}
+intrinsic and @code{%LOC()} construct now return
+values of integer type that is the same width (holds
+the same number of bits) as the pointer type on the
+machine.
+
+On most machines, this won't make a difference, whereas
+on Alphas, the type these constructs return is
+@code{INTEGER*8} instead of the more common @code{INTEGER*4}.
+
+@item
+Emulate @code{COMPLEX} arithmetic in the @code{g77} front
+end, to avoid bugs in @code{complex} support in the
+@code{gcc} back end.
+New option @samp{-fno-emulate-complex}

+Fix @code{g77} command driver so that @samp{g77 -o foo.f}
+no longer deletes @file{foo.f} before issuing other
+diagnostics, and so the @samp{-x} option is properly
+handled.
+
+@item
+Enable inlining of subroutines and functions by the @code{gcc}
+back end.
+This works as it does for @code{gcc} itself---program units
+may be inlined for invocations that follow them in the same
+program unit, as long as the appropriate compile-time
+options are specified.
+
+@item
+Dummy arguments are no longer assumed to potentially alias
+(overlap)
+other dummy arguments or @code{COMMON} areas when any of
+these are defined (assigned to) by Fortran code.
+
+This can result in faster and/or smaller programs when
+compiling with optimization enabled, though on some
+systems this effect is observed only when @samp{-fforce-addr}
+also is specified.
+
+New options @samp{-falias-check}, @samp{-fargument-alias},
+@samp{-fargument-noalias},
+and @samp{-fno-argument-noalias-global} control the

+The @code{CONJG()} and @code{DCONJG()} intrinsics now
+are compiled in-line.
+
+@item
+The bug-fix for 0.5.19.1 has been re-done.
+The @code{g77} compiler has been changed back to
+assume @code{libf2c} has no aliasing problems in
+its implementations of the @code{COMPLEX} (and
+@code{DOUBLE COMPLEX}) intrinsics.
+The @code{libf2c} has been changed to have no such
+problems.
+
+As a result, 0.5.20 is expected to offer improved performance
+over 0.5.19.1, perhaps as good as 0.5.19 in most
+or all cases, due to this change alone.
+
+@emph{Note:} This change requires version 0.5.20 of
+@code{libf2c}, at least, when linking code produced
+by any versions of @code{g77} other than 0.5.19.1.
+Use @samp{g77 -v} to determine the version numbers
+of the @code{libF77}, @code{libI77}, and @code{libU77}
+components of the @code{libf2c} library.
+(If these version numbers are not printed---in
+particular, if the linker complains about unresolved
+references to names like @samp{g77__fvers__}---that
+strongly suggests your installation has an obsolete
+version of @code{libf2c}.)

+(Normally, @code{g77} uses a separate memory location

+while @code{WORD} corresponds to @code{INTEGER*2}.
+
+Thanks to Scott Snyder (@email{snyder@@d0sgif.fnal.gov})
+for providing the patch for this!
+
+@item
+The compiler code handling intrinsics has been largely
+rewritten to accommodate the new types.
+No new intrinsics or arguments for existing
+intrinsics have been added, so there is, at this
+point, no intrinsic to convert to @code{INTEGER*8},
+for example.
+
+@item
+Support automatic arrays in procedures.
+
+@item
+Reduce space/time requirements for handling large
+@emph{sparsely} initialized aggregate arrays.
+This improvement applies to only a subset of
+the general problem to be addressed in 0.6.
+
+@item
+Treat initial values of zero as if they weren't

+The initial values will be set to zero anyway, but the amount
+of compile time processing them will be reduced,
+in some cases significantly (though, again, this
+is only a subset of the general problem to be

+
+A new option, @samp{-fzeros}, is introduced to

+With @samp{-ff90} in force, @code{g77} incorrectly

+(Here, @samp{Z} is @code{DOUBLE COMPLEX}.)
+
+With @samp{-fno-f90} in force, the interpretation remains
+unchanged, since this appears to be how at least some
+F77 code using the @code{DOUBLE COMPLEX} extension expected
+it to work.
+
+Essentially, @samp{REAL(Z)} in F90 is the same as
+@samp{DBLE(Z)}, while in extended F77, it appears to
+be the same as @samp{REAL(REAL(Z))}.
+
+@item
+An expression involving exponentiation, where both operands

+(these involved an errant diagnostic and a crash, both on good

+@item
+Close @code{INCLUDE} files after processing them, so compiling source
+files with lots of @code{INCLUDE} statements does not result in

+
+@item
+Speed up compiling, especially of larger programs, and perhaps
+slightly reduce memory utilization while compiling (this is
+@emph{not} the improvement planned for 0.6 involving large aggregate
+areas)---these improvements result from simply turning
+off some low-level code to do self-checking that hasn't been
+triggered in a long time.
+

+Introduce three new options that

+These options are @samp{-fmove-all-movables}, @samp{-freduce-all-givs},

+for Fortran compilations.
+These optimizations are intended to help toon Fortran programs.
+
+@item
+Patch the GBE to do a better job optimizing certain
+kinds of references to array elements.
+
+@item
+Due to patches to the GBE, the version number of @code{gcc}
+also is patched to make it easier to manage installations,
+especially useful if it turns out a @code{g77} change to the
+GBE has a bug.
+
+The @code{g77}-modified version number is the @code{gcc}
+version number with the string @samp{.f.@var{n}} appended,
+where @samp{f} identifies the version as enhanced for
+Fortran, and @var{n} is @samp{1} for the first Fortran
+patch for that version of @code{gcc}, @samp{2} for the
+second, and so on.
+
+So, this introduces version 2.7.2.f.1 of @code{gcc}.
+
+@item
+Make several improvements and fixes to diagnostics, including
+the removal of two that were inappropriate or inadequate.

+Warning about two successive arithmetic operators, produced

+@samp{-Wsurprising} now warns about the remaining cases
+of using non-integral variables for implied-@code{DO}
+loops, instead of these being rejected unless @samp{-fpedantic}
+or @samp{-fugly} specified.
+
+@item
+Allow @code{SAVE} of a local variable or array, even after
+it has been given an initial value via @code{DATA}, for example.
+
+@item
+Introduce an Info version of @code{g77} documentation, which
+supercedes @file{gcc/f/CREDITS}, @file{gcc/f/DOC}, and
+@file{gcc/f/PROJECTS}.
+These files will be removed in a future release.
+The files @file{gcc/f/BUGS}, @file{gcc/f/INSTALL}, and
+@file{gcc/f/NEWS} now are automatically built from
+the texinfo source when distributions are made.
+
+This effort was inspired by a first pass at translating
+@file{g77-0.5.16/f/DOC} that was contributed to Craig by
+David Ronis (@email{ronis@@onsager.chem.mcgill.ca}).
+
+@item
+New @samp{-fno-second-underscore} option to specify
+that, when @samp{-funderscoring} is in effect, a second
+underscore is not to be appended to Fortran names already
+containing an underscore.
+
+@item
+Change the way iterative @code{DO} loops work to follow
+the F90 standard.
+In particular, calculation of the iteration count is
+still done by converting the start, end, and increment
+parameters to the type of the @code{DO} variable, but
+the result of the calculation is always converted to
+the default @code{INTEGER} type.
+
+(This should have no effect on existing code compiled
+by @code{g77}, but code written to assume that use
+of a @emph{wider} type for the @code{DO} variable

+have side effects), so to get the return values from @code{SIGNAL}
+and @code{SYSTEM}, append a final argument specifying an @code{INTEGER}
+variable or array element (e.g. @samp{CALL SYSTEM('rm foo',ISTAT)}).
+
+@item
+Add new intrinsic group named @samp{unix} to contain the new intrinsics,
+and by default enable this new group.
+
+@item
+Move @code{LOC()} intrinsic out of the @samp{vxt} group to the new
+@samp{unix} group.
+
+@item
+Improve @code{g77} so that @samp{g77 -v} by itself (or with
+certain other options, including @samp{-B}, @samp{-b}, @samp{-i},
+@samp{-nostdlib}, and @samp{-V}) reports lots more useful
+version info, and so that long-form options @code{gcc} accepts are
+understood by @code{g77} as well (even in truncated, unambiguous forms).
+
+@item
+Add new @code{g77} option @samp{--driver=name} to specify driver when
+default, @code{gcc}, isn't appropriate.
+
+@item
+Add support for @samp{#} directives (as output by the preprocessor) in the
+compiler, and enable generation of those directives by the
+preprocessor (when compiling @samp{.F} files) so diagnostics and debugging
+info are more useful to users of the preprocessor.
+
+@item
+Produce better diagnostics, more like @code{gcc}, with info such as
+@samp{In function `foo':} and @samp{In file included from...:}.
+
+@item
+Support @code{gcc}'s @samp{-fident} and @samp{-fno-ident} options.
+
+@item
+When @samp{-Wunused} in effect, don't warn about local variables used as
+statement-function dummy arguments or @code{DATA} implied-@code{DO} iteration
+variables, even though, strictly speaking, these are not uses
+of the variables themselves.
+
+@item
+When @samp{-W -Wunused} in effect, don't warn about unused dummy arguments
+at all, since there's no way to turn this off for individual
+cases (@code{g77} might someday start warning about these)---applies
+to @code{gcc} versions 2.7.0 and later, since earlier versions didn't
+warn about unused dummy arguments.
+
+@item
+New option @samp{-fno-underscoring} that inhibits transformation of names
+(by appending one or two underscores) so users may experiment
+with implications of such an environment.
+
+@item
+Minor improvement to @file{gcc/f/info} module to make it easier to build
+@code{g77} using the native (non-@code{gcc}) compiler on certain machines
+(but definitely not all machines nor all non-@code{gcc} compilers).
+Please
+do not report bugs showing problems compilers have with
+macros defined in @file{gcc/f/target.h} and used in places like
+@file{gcc/f/expr.c}.
+
+@item
+Add warning to be printed for each invocation of the compiler
+if the target machine @code{INTEGER}, @code{REAL}, or @code{LOGICAL} size
+is not 32 bits,
+since @code{g77} is known to not work well for such cases (to be
+fixed in Version 0.6---@pxref{Actual Bugs,,Actual Bugs We Haven't Fixed Yet}).
+
+@item
+Lots of new documentation (though work is still needed to put it into
+canonical GNU format).
+
+@item
+Build @code{libf2c} with @samp{-g0}, not @samp{-g2}, in effect
+(by default), to produce
+smaller library without lots of debugging clutter.
+@end itemize
+
+@c 1995-05-19: 0.5.15 released.
+@heading In 0.5.15:
+@itemize @bullet
+@item
+Fix bad code generation involving @samp{X**I} and temporary, internal variables
+generated by @code{g77} and the back end (such as for @code{DO} loops).
+
+@item
+Fix crash given @samp{CHARACTER A;DATA A/.TRUE./}.
+
+@item
+Replace crash with diagnostic given @samp{CHARACTER A;DATA A/1.0/}.
+
+@item
+Fix crash or other erratic behavior when null character constant
+(@samp{''}) is encountered.
+
+@item
+Fix crash or other erratic behavior involving diagnosed code.
+
+@item
+Fix code generation for external functions returning type @code{REAL} when
+the @samp{-ff2c} option is in force (which it is by default) so that
+@code{f2c} compatibility is indeed provided.
+
+@item
+Disallow @samp{COMMON I(10)} if @samp{I} has previously been specified
+with an array declarator.
+
+@item
+New @samp{-ffixed-line-length-@var{n}} option, where @var{n} is the
+maximum length
+of a typical fixed-form line, defaulting to 72 columns, such
+that characters beyond column @var{n} are ignored, or @var{n} is @samp{none},
+meaning no characters are ignored.
+does not affect lines
+with @samp{&} in column 1, which are always processed as if
+@samp{-ffixed-line-length-none} was in effect.
+
+@item
+No longer generate better code for some kinds of array references,
+as @code{gcc} back end is to be fixed to do this even better, and it
+turned out to slow down some code in some cases after all.
+
+@item
+In @code{COMMON} and @code{EQUIVALENCE} areas with any members given initial
+values (e.g. via @code{DATA}), uninitialized members now always
+initialized to binary zeros (though this is not required by
+the standard, and might not be done in future versions
+of @code{g77}).
+Previously, in some @code{COMMON}/@code{EQUIVALENCE} areas
+(essentially those with members of more than one type), the
+uninitialized members were initialized to spaces, to
+cater to @code{CHARACTER} types, but it seems no existing code expects
+that, while much existing code expects binary zeros.
+@end itemize
+
+@heading In 0.5.14:
+@itemize @bullet
+@item
+Don't emit bad code when low bound of adjustable array is nonconstant
+and thus might vary as an expression at run time.
+
+@item
+Emit correct code for calculation of number of trips in @code{DO} loops
+for cases
+where the loop should not execute at all.
+(This bug affected cases
+where the difference between the begin and end values was less
+than the step count, though probably not for floating-point cases.)
+
+@item
+Fix crash when extra parentheses surround item in
+@code{DATA} implied-@code{DO} list.
+
+@item
+Fix crash over minor internal inconsistencies in handling diagnostics,
+just substitute dummy strings where necessary.
+
+@item
+Fix crash on some systems when compiling call to @code{MVBITS()} intrinsic.
+
+@item
+Fix crash on array assignment @samp{TYPE@var{ddd}(@dots{})=@dots{}}, where @var{ddd}
+is a string of one or more digits.
+
+@item
+Fix crash on @code{DCMPLX()} with a single @code{INTEGER} argument.
+
+@item
+Fix various crashes involving code with diagnosed errors.
+
+@item
+Support @samp{-I} option for @code{INCLUDE} statement, plus @code{gcc}'s
+@file{header.gcc} facility for handling systems like MS-DOS.
+
+@item
+Allow @code{INCLUDE} statement to be continued across multiple lines,
+even allow it to coexist with other statements on the same line.
+
+@item
+Incorporate Bellcore fixes to @code{libf2c} through 1995-03-15---this
+fixes a bug involving infinite loops reading EOF with empty list-directed
+I/O list.
+
+@item
+Remove all the @code{g77}-specific auto-configuration scripts, code,
+and so on,
+except for temporary substitutes for bsearch() and strtoul(), as
+too many configure/build problems were reported in these areas.
+People will have to fix their systems' problems themselves, or at
+least somewhere other than @code{g77}, which expects a working ANSI C
+environment (and, for now, a GNU C compiler to compile @code{g77} itself).
+
+@item
+Complain if initialized common redeclared as larger in subsequent program
+unit.
+
+@item
+Warn if blank common initialized, since its size can vary and hence
+related warnings that might be helpful won't be seen.
+
+@item
+New @samp{-fbackslash} option, on by default, that causes @samp{\}
+within @code{CHARACTER}
+and Hollerith constants to be interpreted a la GNU C.
+Note that
+this behavior is somewhat different from @code{f2c}'s, which supports only
+a limited subset of backslash (escape) sequences.
+
+@item
+Make @samp{-fugly-args} the default.
+
+@item
+New @samp{-fugly-init} option, on by default, that allows typeless/Hollerith
+to be specified as initial values for variables or named constants
+(@code{PARAMETER}), and also allows character<->numeric conversion in
+those contexts---turn off via @samp{-fno-ugly-init}.
+
+@item
+New @samp{-finit-local-zero} option to initialize
+local variables to binary zeros.
+This does not affect whether they are @code{SAVE}d, i.e. made
+automatic or static.
+
+@item
+New @samp{-Wimplicit} option to warn about implicitly typed variables, arrays,
+and functions.
+(Basically causes all program units to default to @code{IMPLICIT NONE}.)
+
+@item
+@samp{-Wall} now implies @samp{-Wuninitialized} as with @code{gcc}
+(i.e. unless @samp{-O} not specified, since @samp{-Wuninitialized}
+requires @samp{-O}), and implies @samp{-Wunused} as well.
+
+@item
+@samp{-Wunused} no longer gives spurious messages for unused
+@code{EXTERNAL} names (since they are assumed to refer to block data
+program units, to make use of libraries more reliable).
+
+@item
+Support @code{%LOC()} and @code{LOC()} of character arguments.
+
+@item
+Support null (zero-length) character constants and expressions.
+
+@item
+Support @code{f2c}'s @code{IMAG()} generic intrinsic.
+
+@item
+Support @code{ICHAR()}, @code{IACHAR()}, and @code{LEN()} of
+character expressions that are valid in assignments but
+not normally as actual arguments.
+
+@item
+Support @code{f2c}-style @samp{&} in column 1 to mean continuation line.
+
+@item
+Allow @code{NAMELIST}, @code{EXTERNAL}, @code{INTRINSIC}, and @code{VOLATILE}
+in @code{BLOCK DATA}, even though these are not allowed by the standard.
+
+@item
+Allow @code{RETURN} in main program unit.
+
+@item
+Changes to Hollerith-constant support to obey Appendix C of the
+standard:
+
+@itemize --
+@item
+Now padded on the right with zeros, not spaces.
+
+@item
+Hollerith ``format specifications'' in the form of arrays of
+non-character allowed.
+
+@item
+Warnings issued when non-space truncation occurs when converting
+to another type.
+
+@item
+When specified as actual argument, now passed
+by reference to @code{INTEGER} (padded on right with spaces if constant
+too small, otherwise fully intact if constant wider the @code{INTEGER}
+type) instead of by value.
+@end itemize
+
+@strong{Warning:} @code{f2c} differs on the
+interpretation of @samp{CALL FOO(1HX)}, which it treats exactly the
+same as @samp{CALL FOO('X')}, but which the standard and @code{g77} treat
+as @samp{CALL FOO(%REF('X   '))} (padded with as many spaces as necessary
+to widen to @code{INTEGER}), essentially.
+
+@item
+Changes and fixes to typeless-constant support:
+
+@itemize --
+@item
+Now treated as a typeless double-length @code{INTEGER} value.
+
+@item
+Warnings issued when overflow occurs.
+
+@item
+Padded on the left with zeros when converting
+to a larger type.
+
+@item
+Should be properly aligned and ordered on
+the target machine for whatever type it is turned into.
+
+@item
+When specified as actual argument, now passed as reference to
+a default @code{INTEGER} constant.
+@end itemize
+
+@item
+@code{%DESCR()} of a non-@code{CHARACTER} expression now passes a pointer to
+the expression plus a length for the expression just as if
+it were a @code{CHARACTER} expression.
+For example, @samp{CALL FOO(%DESCR(D))}, where
+@samp{D} is @code{REAL*8}, is the same as @samp{CALL FOO(D,%VAL(8)))}.
+
+@item
+Name of multi-entrypoint master function changed to incorporate
+the name of the primary entry point instead of a decimal
+value, so the name of the master function for @samp{SUBROUTINE X}
+with alternate entry points is now @samp{__g77_masterfun_x}.
+
+@item
+Remove redundant message about zero-step-count @code{DO} loops.
+
+@item
+Clean up diagnostic messages, shortening many of them.
+
+@item
+Fix typo in @code{g77} man page.
+
+@item
+Clarify implications of constant-handling bugs in @file{f/BUGS}.
+
+@item
+Generate better code for @samp{**} operator with a right-hand operand of
+type @code{INTEGER}.
+
+@item
+Generate better code for @code{SQRT()} and @code{DSQRT()},
+also when @samp{-ffast-math}
+specified, enable better code generation for @code{SIN()} and @code{COS()}.
+
+@item
+Generate better code for some kinds of array references.
+
+@item
+Speed up lexing somewhat (this makes the compilation phase noticeably
+faster).

+
+   Description:
+      The high-level input level to statement handling for the rest of the
+      FFE.  ffest_first is the first state for the lexer to invoke to start
+      a statement.  A statement normally starts with a NUMBER token (to indicate
+      a label def) followed by a NAME token (to indicate what kind of statement
+      it is), though of course the NUMBER token may be omitted.	 ffest_first
+      gathers the first NAME token and returns a state of ffest_second_,
+      where the trailing underscore means "internal to ffest" and thus outside
+      users should not depend on this.	ffest_second_ then looks at the second
+      token in conjunction with the first, decides what possible statements are
+      meant, and tries each possible statement in turn, from most likely to
+      least likely.  A successful attempt currently is recorded, and further
+      successful attempts by other possibilities raise an assertion error in
+      ffest_confirmed (this is to detect ambiguities).	A failure in an
+      attempt is signaled by calling ffest_ffebad_start; this results in the
+      next token sent by ffest_save_ (the intermediary when more than one
+      possible statement exists) being EOS to shut down processing and the next
+      possibility tried.
+
+      When all possibilities have been tried, the successful one is retried with
+      inhibition turned off (FALSE) as reported by ffest_is_inhibited().  If
+      there is no successful one, the first one is retried so the user gets to
+      see the error messages.
+
+      In the future, after syntactic bugs have been reasonably shaken out and
+      ambiguities thus detected, the first successful possibility will be
+      enabled (inhibited goes FALSE) as soon as it confirms success by calling
+      ffest_confirmed, thus retrying the possibility will not be necessary.
+
+      The only complication in all this is that expression handling is
+      happening while possibilities are inhibited.  It is up to the expression
+      handler, conceptually, to not make any changes to its knowledge base for
+      variable names and so on when inhibited that cannot be undone if
+      the current possibility fails (shuts down via ffest_ffebad_start).  In
+      fact, this business is handled not be ffeexpr, but by lower levels.
+
+      ffesta functions serve only to provide information used in syntactic
+      processing of possible statements, and thus may not make changes to the
+      knowledge base for variables and such.
+
+      ffestb functions perform the syntactic analysis for possible statements,
+      and thus again may not make changes to the knowledge base except under the
+      auspices of ffeexpr and its subordinates, changes which can be undone when
+      necessary.
+
+      ffestc functions perform the semantic analysis for the chosen statement,
+      and thus may change the knowledge base as necessary since they are invoked
+      by ffestb functions only after a given statement is confirmed and
+      enabled.	Note, however, that a few ffestc functions (identified by
+      their statement names rather than grammar numbers) indicate valid forms
+      that are, outside of any context, ambiguous, such as ELSE WHERE and
+      PRIVATE; these functions should make a quick decision as to what is
+      intended and dispatch to the appropriate specific ffestc function.
+
+      ffestd functions actually implement statements.  When called, the
+      statement is considered valid and is either an executable statement or
+      a nonexecutable statement with direct-output results.  For example, CALL,
+      GOTO, and assignment statements pass through ffestd because they are
+      executable; DATA statements pass through because they map directly to the
+      output file (or at least might so map); ENTRY statements also pass through
+      because they essentially affect code generation in an immediate way;
+      whereas INTEGER, SAVE, and SUBROUTINE statements do not go through
+      ffestd functions because they merely update the knowledge base.

+      st.c
+
+   Description:
+      Parses the proper form for statements, builds up expression trees for
+      them, but does not actually implement them.  Uses ffebad (primarily via
+      ffesta_ffebad_start) to indicate errors in form.	In many cases, an invalid
+      statement form indicates another possible statement needs to be looked at
+      by ffest.	 In a few cases, a valid statement form might not completely
+      determine the nature of the statement, as in REALFUNCTIONA(B), which is
+      a valid form for either the first statement of a function named A taking
+      an argument named B or for the declaration of a real array named FUNCTIONA
+      with an adjustable size of B.  A similar (though somewhat easier) choice
+      must be made for the statement-function-def vs. assignment forms, as in
+      the case of FOO(A) = A+2.0.
+
+      A given parser consists of one or more state handlers, the first of which
+      is the initial state, and the last of which (for any given input) returns
+      control to a final state handler (ffesta_zero or ffesta_two, explained
+      below).  The functions handling the states for a given parser usually have
+      the same names, differing only in the final number, as in ffestb_foo_
+      (handles the initial state), ffestb_foo_1_, ffestb_foo_2_ (handle
+      subsequent states), although liberties sometimes are taken with the "foo"
+      part either when keywords are clarified into given statements or are
+      transferred into other possible areas.  (For example, the type-name
+      states can hop over to _dummy_ functions when the FUNCTION or RECURSIVE
+      keywords are seen, though this kind of thing is kept to a minimum.)  Only
+      the names without numbers are exported to the rest of ffest; the others
+      are local (static).
+
+      Each initial state is provided with the first token in ffesta_tokens[0],
+      which will be killed upon return to the final state (ffesta_zero or
+      ffelex_swallow_tokens passed through to ffesta_zero), so while it may
+      be changed to another token, a valid token must be left there to be
+      killed.  Also, a "convenient" array of tokens are left in
+      ffesta_tokens[1..FFESTA_tokensMAX].  The initial state of this set of
+      elements is undefined, thus, if tokens are stored here, they must be
+      killed before returning to the final state.  Any parser may also use
+      cross-state local variables by sticking a structure containing storage
+      for those variables in the local union ffestb_local_ (unless the union
+      goes on strike).	Furthermore, parsers that handle more than one first or
+      second tokens (like _varlist_, which handles EXTERNAL, INTENT, INTRINSIC,
+      OPTIONAL,
+      PUBLIC, or PRIVATE, and _endxyz_, which handles ENDBLOCK, ENDBLOCKDATA,
+      ENDDO, ENDIF, and so on) may expect arguments from ffest in the
+      ffest-wide union ffest_args_, the substructure specific to the parser.
+
+      A parser's responsibility is: to call either ffesta_confirmed or
+      ffest_ffebad_start before returning to the final state; to be the only
+      parser that can possibly call ffesta_confirmed for a given statement;
+      to call ffest_ffebad_start immediately upon recognizing a bad token
+      (specifically one that another statement parser might confirm upon);
+      to call ffestc functions only after calling ffesta_confirmed and only
+      when ffesta_is_inhibited returns FALSE; and to call ffesta_is_inhibited
+      only after calling ffesta_confirmed.  Confirm as early as reasonably
+      possible, even when only one ffestc function is called for the statement
+      later on, because early confirmation can enhance the error-reporting
+      capabilities if a subsequent error is detected and this parser isn't
+      the first possibility for the statement.
+
+      To assist the parser, functions like ffesta_ffebad_1t and _1p_ have
+      been provided to make use of ffest_ffebad_start fairly easy.

+
+   Description:
+      Verifies the proper semantics for statements, checking expressions already
+      semantically analyzed individually, collectively, checking label defs and
+      refs, and so on.	Uses ffebad to indicate errors in semantics.
+
+      In many cases, both a token and a keyword (ffestrFirst, ffestrSecond,
+      or ffestrOther) is provided.  ONLY USE THE TOKEN as a pointer to the
+      source-code location for an error message or similar; use the keyword
+      as the semantic matching for the token, since the token's text might
+      not match the keyword's code.  For example, INTENT(IN OUT) A in free
+      source form passes to ffestc_R519_start the token "IN" but the keyword
+      FFESTR_otherINOUT, and the latter is correct.
+
+      Generally, either a single ffestc function handles an entire statement,
+      in which case its name is ffestc_xyz_, or more than one function is
+      needed, in which case its names are ffestc_xyz_start_,
+      ffestc_xyz_item_ or ffestc_xyz_item_abc_, and ffestc_xyz_finish_.
+      The caller must call _start_ before calling any _item_ functions, and
+      must call _finish_ afterwards.  If it is clearly a syntactic matter as
+      to restrictions on the number and variety of _item_ calls, then the caller
+      should report any errors and ffestc_ should presume it has been taken
+      care of and handle any semantic problems with grace and no error messages.
+      If the permitted number and variety of _item_ calls has some basis in
+      semantics, then the caller should not generate any messages and ffestc
+      should do all the checking.
+
+      A few ffestc functions have names rather than grammar numbers, like
+      ffestc_elsewhere and ffestc_end.	These are cases where the actual
+      statement depends on its context rather than just its form; ELSE WHERE
+      may be the obvious (WHERE...ELSE WHERE...END WHERE) or something a little
+      more subtle (WHERE: IF THEN...ELSE WHERE...END IF WHERE).	 The actual
+      ffestc functions do exist and do work, but may or may not be invoked
+      by ffestb depending on whether some form of resolution is possible.
+      For example, ffestc_R1103 end-program-stmt is reachable directly when
+      END PROGRAM [name] is specified, or via ffestc_end when END is specified
+      and the context is a main program.  So ffestc_xyz_ should make a quick
+      determination of the context and pick the appropriate ffestc_Nxyz_
+      function to invoke, without a lot of ceremony.

+/* As of 0.5.4, any statement that calls on ffecom to transform an
+   expression might need to be wrapped in ffecom_push_calltemps ()
+   and ffecom_pop_calltemps () as are some other cases.  That is
+   the case when the transformation might involve generation of
+   a temporary that must be auto-popped, the specific case being
+   when a COMPLEX operation requiring a call to libf2c being
+   generated, whereby a temp is needed to hold the result since
+   libf2c doesn't return COMPLEX results directly.  Cases where it
+   is known that ffecom_expr () won't need to do this, such as
+   the CALL statement (where it's the transformation of the
+   call expr itself that does the wrapping), don't need to bother
+   with this wrapping.  Forgetting to do the wrapping currently
+   means a crash at an assertion when the wrapping would be helpful
+   to keep temporaries from being wasted -- see ffecom_push_tempvar.  */

+
+/* "How g77 learns about symbols"
+
+   There are three primary things in a symbol that g77 uses to keep
+   track of what it has learned about that symbol:
+
+   1.  The state
+   2.  The attributes
+   3.  The info
+
+   State, attributes, and info (see f-info* files) all start out with
+   "NONE" fields when a symbol is first created.
+
+   In a PROGRAM or BLOCK DATA program unit, info where cannot be DUMMY
+   or RESULT.  Any combinations including those possibilities are not
+   considered possible in such program units.
+
+   As soon as a symbol is created, it _must_ have its state changed to
+   SEEN, UNCERTAIN, or UNDERSTOOD.
+
+   If SEEN, some info might be set, such as the type info (as in when
+   the TYPE attribute is present) or kind/where info.
+
+   If UNCERTAIN, the permitted combinations of attributes and info are
+   listed below.  Only the attributes ACTUALARG, ADJUSTABLE, ANYLEN, ARRAY,
+   DUMMY, EXTERNAL, SFARG, and TYPE are permitted.  (All these attributes
+   are contrasted to each attribute below, even though some combinations
+   wouldn't be permitted in SEEN state either.)  Note that DUMMY and
+   RESULT are not permitted in a PROGRAM/BLOCKDATA program unit, which
+   results in some of the combinations below not occurring (not UNCERTAIN,
+   but UNDERSTOOD).
+
+   ANYLEN|TYPE & ~(ACTUALARG|ADJUSTABLE|ARRAY|DUMMY|EXTERNAL|SFARG):
+	ENTITY/DUMMY, ENTITY/RESULT, FUNCTION/INTRINSIC.
+
+   ARRAY & ~(ACTUALARG|ANYLEN|DUMMY|EXTERNAL|SFARG|TYPE):
+	ENTITY/DUMMY, ENTITY/LOCAL.
+
+   ARRAY|TYPE & ~(ACTUALARG|ANYLEN|DUMMY|EXTERNAL|SFARG):
+	ENTITY/DUMMY, ENTITY/LOCAL.
+
+   DUMMY & ~(ACTUALARG|ADJUSTABLE|ANYLEN|ARRAY|EXTERNAL|SFARG|TYPE):
+	ENTITY/DUMMY, FUNCTION/DUMMY, SUBROUTINE/DUMMY.
+
+   DUMMY|TYPE & ~(ACTUALARG|ADJUSTABLE|ANYLEN|ARRAY|EXTERNAL|SFARG):
+	ENTITY/DUMMY, FUNCTION/DUMMY.
+
+   EXTERNAL & ~(ACTUALARG|ADJUSTABLE|ANYLEN|ARRAY|DUMMY|SFARG|TYPE):
+	FUNCTION/DUMMY, FUNCTION/GLOBAL, SUBROUTINE/DUMMY,
+	SUBROUTINE/GLOBAL, BLOCKDATA/GLOBAL.
+
+   EXTERNAL|ACTUALARG & ~(ADJUSTABLE|ANYLEN|ARRAY|DUMMY|SFARG|TYPE):
+	FUNCTION/GLOBAL, SUBROUTINE/GLOBAL.
+
+   EXTERNAL|DUMMY & ~(ACTUALARG|ADJUSTABLE|ANYLEN|ARRAY|SFARG|TYPE):
+	FUNCTION/DUMMY, SUBROUTINE/DUMMY.
+
+   EXTERNAL|TYPE & ~(ACTUALARG|ADJUSTABLE|ANYLEN|ARRAY|DUMMY|SFARG):
+	FUNCTION/DUMMY, FUNCTION/GLOBAL.
+
+   SFARG & ~(ACTUALARG|ADJUSTABLE|ANYLEN|ARRAY|DUMMY|EXTERNAL|TYPE):
+	ENTITY/DUMMY, ENTITY/LOCAL.
+
+   SFARG|TYPE & ~(ACTUALARG|ADJUSTABLE|ANYLEN|ARRAY|DUMMY|EXTERNAL):
+	ENTITY/DUMMY, ENTITY/LOCAL.
+
+   TYPE & ~(ACTUALARG|ANYLEN|ARRAY|DUMMY|EXTERNAL|SFARG):
+	ENTITY/DUMMY, ENTITY/LOCAL, ENTITY/RESULT, FUNCTION/DUMMY,
+	FUNCTION/GLOBAL, FUNCTION/INTRINSIC.
+
+   If UNDERSTOOD, the attributes are no longer considered, and the info
+   field is considered to be as fully filled in as possible by analyzing
+   a single program unit.
+
+   Each of the attributes (used only for SEEN/UNCERTAIN states) is
+   defined and described below.  In many cases, a symbol starts out as
+   SEEN and has attributes set as it is seen in various contexts prior
+   to the first executable statement being seen (the "exec transition").
+   Once that happens, either it becomes immediately UNDERSTOOD and all
+   its info filled in, or it becomes UNCERTAIN and its info only partially
+   filled in until it becomes UNDERSTOOD.  While UNCERTAIN, only a
+   subset of attributes are possible/important.
+
+   Not all symbols reach the UNDERSTOOD state, and in some cases symbols
+   go immediately from NONE to the UNDERSTOOD or even UNCERTAIN state.
+   For example, given "PROGRAM FOO", everything is known about the name
+   "FOO", so it becomes immediately UNDERSTOOD.
+
+   Also, there are multiple name spaces, and not all attributes are
+   possible/permitted in all name spaces.
+
+   The only attributes permitted in the global name space are:
+
+   ANY, CBLOCK, SAVECBLOCK.
+
+   The only attributes permitted in the local name space are:
+
+   ANY, ACTUALARG, ADJUSTABLE, ADJUSTS, ANYLEN, ANYSIZE, ARRAY, COMMON,
+   DUMMY, EQUIV, EXTERNAL, INIT, INTRINSIC, NAMELIST, RESULT, SAVE, SFARG,
+   SFUNC, TYPE.
+
+   In the stmt-func name space, no attributes are used, just the states.

+
+   Description:
+      Implements conversion of lexer tokens to machine-dependent numerical
+      form and accordingly issues diagnostic messages when necessary.
+
+      Also, this module, especially its .h file, provides nearly all of the
+      information on the target machine's data type, kind type, and length
+      type capabilities.  The idea is that by carefully going through
+      target.h and changing things properly, one can accomplish much
+      towards the porting of the FFE to a new machine.	There are limits
+      to how much this can accomplish towards that end, however.  For one
+      thing, the ffeexpr_collapse_convert function doesn't contain all the
+      conversion cases necessary, because the text file would be
+      enormous (even though most of the function would be cut during the
+      cpp phase because of the absence of the types), so when adding to
+      the number of supported kind types for a given type, one must look
+      to see if ffeexpr_collapse_convert needs modification in this area,
+      in addition to providing the appropriate macros and functions in
+      ffetarget.  Note that if combinatorial explosion actually becomes a
+      problem for a given machine, one might have to modify the way conversion
+      expressions are built so that instead of just one conversion expr, a
+      series of conversion exprs are built to make a path from one type to
+      another that is not a "near neighbor".  For now, however, with a handful
+      of each of the numeric types and only one character type, things appear
+      manageable.
+
+      A nonobvious change to ffetarget would be if the target machine was
+      not a 2's-complement machine.  Any item with the word "magical" (case-
+      insensitive) in the FFE's source code (at least) indicates an assumption
+      that a 2's-complement machine is the target, and thus that there exists
+      a magnitude that can be represented as a negative number but not as
+      a positive number.  It is possible that this situation can be dealt
+      with by changing only ffetarget, for example, on a 1's-complement
+      machine, perhaps #defineing ffetarget_constant_is_magical to simply
+      FALSE along with making the appropriate changes in ffetarget's number
+      parsing functions would be sufficient to effectively "comment out" code
+      in places like ffeexpr that do certain magical checks.  But it is
+      possible there are other 2's-complement dependencies lurking in the
+      FFE (as possibly is true of any large program); if you find any, please
+      report them so we can replace them with dependencies on ffetarget
+      instead.
