+Mon Dec 30 10:57:02 1991 Per Bothner (bothner at cygnus.com)
+
+ Mainly stuff to improve handling of TYPE_CODE_REF values.
+ * valops.c (value_addr): If taking the addres of a
+ TYPE_CODE_REF, just cast the object to the corresponding
+ TYPE_CODE_PTR. This yields correct C++ semantics, and
+ preserves the location information, which has the nice effect
+ that &(&R) given the location containing R.
+ * values.c (value_copy): Make non-static (used by value_addr).
+ * eval.c (evaluate_subexp_for_address): Use the default
+ scheme (with value_addr) for a variable if it has TYPE_CODE_REF.
+ * valops.c (value_addr), eval.c (evaluate_subexp_for_address,
+ evaluate_subexp_with_coercion): Factor out some common
+ expressions into variables, for easier reading.
+ * findvar.c (locate_var_value): Remove code to handle
+ TYPE_CODE_REF - it should no longer be needed.
+ * valops.c (value_assign): Do a COERCE_REF on the
+ destination operand, for correct C++ semantics.
+ * valarith.c (value_x_binop): Ditto: De-reference C++
+ references in the arguments.
+ * valops.c: ANSI-fy: bcopy->memcpy, bzero->memset.
+
+Sat Dec 28 11:30:26 1991 Per Bothner (bothner at cygnus.com)
+
+ * dwarfread.c, coffread.c: Use INIT_CPLUS_SPECIFIC.
+ * symtab.c (gdb_mangle_name): Recognize and handle
+ constructors specially.
+ * symtab.c (check_stub_method): Test for failure from
+ cplus-demangle by calling error() instead of seg-faulting ...
+
+Fri Dec 27 22:21:30 1991 Fred Fish (fnf at cygnus.com)
+
+ * defs.h: Add definition of null_cleanup()
+
+ * procfs.c: Many small changes to add base support for a new
+ "info proc" command (currently only printing of the address
+ space mapping is implemented) and allow iteration over the
+ address space mapping, calling an arbitrary function for each
+ mapping (used for shared library support).
+
+ * solib.c: Change all ifdefs that checked for "sun" to check
+ for "!SVR4_SHARED_LIBS" instead. Rewrite lookup_base() to
+ handle locating the debug base address even when not currently
+ stopped at the dynamic linker entry point.
+
+ * utils.c: Add null_cleanup() as a known function that does
+ nothing to serve as a base for possibly long cleanup chains
+ with no specific "first cleanup" to serve as an anchor.
+
+ * xm-sysv4.h: Add define of SVR4_SHARED_LIBS
+
+Fri Dec 27 10:11:33 1991 Per Bothner (bothner at cygnus.com)
+
+ * arm-opcode.h, m88k-opcode.h, pn-opcode.h, np1-opcode.h,
+ pyr-opcode.h, tahoe-opcode, vax-opcode.h: Removed -
+ these are all essentially the same as the versions
+ in ../include/opcode. The remaining *-opcode.h here
+ are not quite so obviously the same, and need study.
+ * arm-pinsn.c, gould-pinsn.c, m88k-pinsn.c, pyr-pinsn.c,
+ tahoe-pinsn.c, vax-pinsn.c: Change so these include
+ opcode/FOO.h (actually ../include/opcode/FOO.h)
+ instead of the recenntly departed opcode-FOO.h files.
+ * sparc-pinsn.c: Now that we're using the much tighter
+ opcode table in ../include/opcode/sparc.h, we shouldn't
+ need to sort the opcodes before dis-assembly.
+
+ * symtab.h, symmisc.c: Make cplus_struct_default be const.
+ * symtab.h, buildsym.c: Add and use INIT_CPLUS_SPECIFIC macro.
+ * symmisc.c: Remove unused 'nfields' variable.
+ * buildsym.h: Add extern decl of unknown_symtype_complaint,
+ since it used used by partial-stab.h (included two places).
+ * partial-stab.h: Re-arrange DBXREAD_ONLY #ifdefs so that
+ we should never hit the default case (until new stab codes
+ are added). Hence, we can leave the complaint in the
+ default case in even when DBXREAD_ONLY is off.
+ * partial_stab.h: Recognize a pair of N_SO stabs (one for the
+ directory, one for the filename proper) without peeking ahead.
+ * dbxread.c, mipsread.c: Because of previous change, don't need
+ ugly CHECK_SECOND_N_SO macro.
+ * buildsym.h, dbxread.c, mipsread.c: Make next_symbol_text a
+ macro that invokes a function pointer in next_symbol_text_func.
+ * mipsread.c: Added comments various places to
+ explain what is going on.
+ * mipsread.c (parse_symbol): Support the new (SGI-specific?)
+ symbol types stStruct, stUnion, and stEnum.
+ Also, some fixes in the code for dealing with tags.
+ * mipsread.c: Change handling of startup_file_start and _end
+ - now just use the textlow and texhigh of a psymtab
+ to check if we've found the startup-file.
+ * mipsread.c: Replace s_idx by global cur_sdx in many places.
+ This is so mips_next_symbol_text can get at it.
+
+Thu Dec 26 19:52:01 1991 Fred Fish (fnf at cygnus.com)
+
+ * dbxread.c, symmisc.c: Move add_psymbol_to_plist() from
+ dbxread.c to symmisc and change name to add_psymbol_to_list.
+ Ditto for add_psymbol_addr_to_plist(). Also expand their
+ body to not use ADD_PSYMBOL_VT_TO_LIST.
+
+ * dwarfread.c: Remove add_psymbol_to_list() and convert usages
+ to the ADD_PSYMBOL_TO_LIST macro.
+
+ * ieee-float.c: Change "#ifdef DEBUG" to "#ifdef IEEE_DEBUG"
+ to avoid collision with the DEBUG for ADD_PSYMBOL_VT_TO_LIST.
+
+ * partial-stab.h, symfile.h: Move definitions of the macros
+ ADD_PSYMBOL_TO_LIST and ADD_PSYMBOL_ADDR_TO_LIST from
+ partial-stab.h to symfile.h. They aren't stab specific.
+ Change ADD_PSYMBOL_VT_TO_LIST to use memcpy rather than strncpy.
+
+Tue Dec 24 11:38:08 1991 John Gilmore (gnu at cygnus.com)
+
+ * Makefile.in: Roll VERSION to 4.3.2.
+
+Mon Dec 23 13:54:35 1991 Per Bothner (bothner at cygnus.com)
+
+ * m68k-opcode.h, mips-opcode.h, sparc-opcode.h: Deleted.
+ * m68k-pinsn.c, mips-pinsn.c, sparc-pinsn.c:
+ Include <opcode/FOO.h> instead of <FOO-opcode.h>.
+
+ * symtab.h, symtab.c, coffread.c, dwarfread.c, symmisc.c,
+ dbxread.c: The TYPE_CPLUS_SPECIFIC structure is now only
+ allocated when it is needed. Until it is needed, it points
+ to a shared statically allocated structure.
+
+ * buildsym.h, buildsym.c, dbxread.c: Remove the kludgy code
+ in read_ofile_symtab to recognize two initial N_SO stabs,
+ and let process_on_symbol handle it. This is cleaner, more
+ efficient, and lets mipsread.c share the same code.
+
+ * symfile.h, partial-stab.h: Move ADD_PSYMBOL_VT_TO_LIST
+ and related macros to here ...
+ * dbxread.c: ... from here.
+ * symmisc.c: Move the "overflow" handling from
+ ADD_PSYMBOL_VT_TO_LIST macro into new function extend_psymbol_list.
+ * dwarfread.c: Re-write add_psymbol_to_list to use
+ ADD_PSYMBOL_VT_TO_LIST macro.
+
+ * mipsread.c: Extend mipsread.c to handle stabs-style symbols
+ encapsulated in ecoff symbols. This enable full g++ debugging.
+ * partial-stab.h: Move the code for pre-scanning symbols
+ and building psymtabs to an include file, out from dbxread.c.
+ This way, the same code can also be used by mipsread.c.
+ * dbxread.c, buildsym.h: Various changes to allow some functions
+ to be used by mipsread.c (also some arguable stylistic changes).
+
+ * tm-mips.h: Define BLOCK_ADDRESS_ABSOLUTE, at least for now,
+ since mips-tfile puts relocatable addresses into LBRAC/RBRAC
+ stabs.
+
+ * mipsread.c: Replace code to handle ambiguous tag blocks.
+ Instead of allocating a TYPE_CODE_UNDEF, guess (by looking
+ at types and offsets) if a tag is a struct, union, or enum.
+ Still patch it later if we find out for sure.
+ * mipsread.c: In various ways, replace Forin's
+ ideo-syncratic code by code that fits better with the
+ rest of gdb, for both stabs-based and ecoff-based symtabs.
+ E.g. use end_psymtab; don't do extra passes over FDR table to
+ pre-partition global data; don't use external symbols to
+ create static/global symbols (just put them in the
+ misc_vector); use ADD_PSYMBOL_TO_LIST macro; don't
+ sort psymtabs or symtabs; use obstacks more.
+
+ * symtab.c, mipsread.c, dbxread.c, buildsym.c:
+ ANSIfy: Replace bcopy by memcpy, bzero by memset.
+
+Sun Dec 22 19:31:04 1991 Fred Fish (fnf at cygnus.com)
+
+ * solib.c (locate_base): Fix uninitialized variable that was
+ causing return of random value to callee.
+
+ * config/mh-amix, config/mh-i386v4: Change to find alloca by
+ compiling and linking alloca.c, even when it is not strictly
+ required. Also arrange to link with -ltermlib rather than
+ -ltermcap.
+
+ * Makefile.in: Move TERMCAP definition to prior to inclusion
+ of host makefile fragments so it can be overridden.
+
+Fri Dec 20 16:33:39 1991 John Gilmore (gnu at cygnus.com)
+
+ * xcoffread.c (read_symbol_lineno): Logic error in incrementing
+ symbol table entry number. (From Metin Ozisik.)
+
+Fri Dec 20 11:36:38 1991 Fred Fish (fnf at cygnus.com)
+
+ * config/mh-i386v4: Change XM_CLIBS to "-lc /usr/ucblib/libucb.a"
+ so compiles with native compilers (without builtin alloca) can
+ pick up the version from the bsd emulation library. However, we
+ search the standard C library first so we don't pick up lots of
+ other broken stuff from libucb.a, that we *don't* want.
+
+ * configure.in, tm-amix.h, tm-i386v4.h, xm-amix.h, xm-i386v4.h:
+ Change svr4 references to sysv4.
+
+ * source.c: Move declaration of external function index to
+ front of file so it is in scope for all references.
+
+ * utils.c (error, fatal): Make definitions consistent with
+ defs.h declarations (declared as "volatile void").
+
+Fri Dec 20 10:55:36 1991 John Gilmore (gnu at cygnus.com)
+
+ * rs6k-opcode.h: Bugfix sfe and stbrx. By Al Kossow.
+
+Wed Dec 18 17:09:06 1991 Stu Grossman (grossman at cygnus.com)
+
+ * command.h, defs.h, eval.h, expression.h, remote-sa.sparc.c,
+ sparc-tdep.c, symtab.h, target.h, value.h, vx-share/ptrace.h,
+ vx-share/xdr_ptrace.h, vx-share/xdr_rdb.h: ANSIfy enums.
+
+Mon Dec 16 12:31:46 1991 Fred Fish (fnf at cygnus.com)
+
+ * config/mt-amix, config/mt-i386v4: Add solib.o to TDEPFILES
+ for these SVR4 systems.
+
+ * symfile.c (symbol_file_add): When verbose is set, print
+ the names of files from which symbols are being loaded, as
+ when from_tty is true.
+
+ * solib.c: Completely reorganized (rewritten) to support
+ SVR4 shared libraries in a manner very close to the original
+ SunOS implementation. This support is expected to change and
+ become more general at some future time. The SVR4 version
+ does not yet work for attached processes, for example.
+
+ * dwarfread.c: Arrange in dwarf_build_psymtabs() for the
+ relocation address to be valid whether or not symbols are
+ being read from a shared library or an executable. Use the
+ relocation address recorded in the psymtab when reading
+ full symbol tables (in read_ofile_symtab). Ensure that the
+ relocated address ranges are recorded in partial symtabs.
+
+ * elfread.c: Add new function elf_interpreter() to return the
+ string from the ELF ".interp" section. This is the interpreter
+ that the kernel tries to run and feed the executable to.
+ Expand arguments to record_misc_function to include a type arg.
+ Modify elf_symtab_read() to supply the type arg, and to do symbol
+ relocations for symbols read in from shared libraries.
+
+ * procfs.c: Add new functions proc_base_address() and
+ proc_address_to_fd(), used by shared library support.
+
+ * tm-svr4.h: Add macros to support SVR4 shared libraries.
+ Definitions for SOLIB_ADD, SOLIB_CREATE_INFERIOR_HOOK,
+ CLEAR_SOLIB, and DISABLE_UNSETTABLE_BREAK.
+
+Fri Dec 13 20:11:26 1991 John Gilmore (gnu at cygnus.com)
+
+ * infrun.c, remote-eb.c, remote-nindy.c, remote-vx.c: Remove
+ unused START_INFERIOR_HOOK.
+
+ * remote-eb.c: Change timeout to 24 seconds (*10 fits in byte)
+ to account for slow loading from floppies.
+ (eb_create_inferior): New fn, from eb_start and
+ nindy_create_inferior.
+ (eb_close): Only use log_file if nonzero.
+ (eb_xfer_inferior_memory): If not writing, then read!
+ (eb_read_inferior_memory, eb_write_inferior_memory): Return length.
+ (eb_kill): A new no-op.
+ (eb_mourn_inferior): Remove breakpoints, then generically weep.
+
+Fri Dec 13 16:09:23 1991 Fred Fish (fnf at cygnus.com)
+
+ * breakpoint.c, findvar.c, infrun.c, putenv.c, stack.c: Fix
+ miscellaneous comparisons of integer with NULL that elicit
+ compiler warnings about comparison of integer with pointer, when
+ NULL is ((void *) 0) rather than just a bare 0.
+
+Wed Dec 11 13:02:58 1991 John Gilmore (gnu at cygnus.com)
+
+ * breakpoint.c (breakpoint_re_set_one): Disable each breakpoint
+ while we reset it, in case of problems. Print breakpoint number
+ in error messages.
+
+ * buildsym.c (read_struct_type): Avoid sun3 compiler bug with
+ foo[--n].
+
+ * source.c (find_source_lines): If getting file mod time fails,
+ don't warn.
+
+ * target.c (target_xfer_memory): If errno is set, return it,
+ rather than EIO.
+
+Tue Dec 10 04:07:22 1991 K. Richard Pixley (rich at rtl.cygnus.com)
+
+ * Makefile.in: infodir belongs in datadir.
+
+Sun Dec 8 21:13:33 1991 Michael Tiemann (tiemann at sphagnum.cygnus.com)
+
+ * symtab.h (struct fn_field): Add new fields `is_private',
+ `is_protected', `is_stub', making room by reducing the size of
+ `voffset'.
+ (struct fn_fieldlist): Delete the fields `private_fn_field_bits'
+ and `protected_fn_field_bits'.
+ (TYPE_FN_{PRIVATE,PROTECTED}_BITS): Deleted.
+ (SET_TYPE_FN_{PRIVATE,PROTECTED}): Deleted.
+ (TYPE_FN_{PRIVATE,PROTECTED}): Deleted.
+ (TYPE_FN_FIELD_{STUB,PRIVATE,PROTECTED}): New macros.
+ * valops.c, valprint.c, symtab.c: All callers updated.
+
+ * buildsym.c (read_struct_type): Delete the `visibility' field
+ from `struct next_fnfield', and rework code so that visibility
+ info is stored into the fn_field directly. Also, hacked to set
+ TYPE_FN_FIELD_STUB for both static and normal member functions.
+
+Sat Dec 7 18:13:11 1991 Fred Fish (fnf at cygnus.com)
+
+ * i386-tdep.c: Fix a problem on i386 systems where buffered code
+ stream access was failing to take into account the minimum size
+ granularity of the code section. For now, the buffering is simply
+ disabled. There is a similar problem in the i386 disassember code
+ that has not yet been fixed (FIXME).
+
+ * gmalloc.c: Use macros to hide some of the ugly casting required
+ in the previously applied fix for pointers with high bits set.
+
+Sat Dec 7 16:49:35 1991 John Gilmore (gnu at cygnus.com)
+
+ * Makefile.in: Roll VERSION to 4.3.1.
+
+Sat Dec 7 04:12:35 1991 John Gilmore (gnu at cygnus.com)
+
+ GDB-4.3 release!
+
+ * Makefile.in: Roll VERSION to 4.3
+ * README, TODO, WHATS.NEW, depend: Update.
+
+ * inflow.c (terminal_inferior): Avoid error msg if attached.
+
+ * gmalloc.c: Fix bug that causes malloc & free to
+ fail on systems where pointers have the high bit set (0x800efcf0
+ for example). The problem is that the difference between two
+ pointers is a signed integer, so the computation
+
+ (char *) 0x800efcf0 - (char *) 0
+
+ yields a negative value. The sign of the result of the modulus
+ operator is machine dependent for negative operands, thus it is
+ possible for it to end up negative. From Fred Fish.
+
+Sat Dec 7 00:00:15 1991 K. Richard Pixley (rich at rtl.cygnus.com)
+
+ * Makefile.in: install using INSTALL_PROGRAM and INSTALL_DATA.
+ added clean-info. added some standards.text support and made it
+ look like our other Makefiles.
+
+ * configure.in: mark this directory target dependent. configure
+ now runs entirely in objdir so make existence tests and
+ references against ${srcdir}.
+
+Fri Dec 6 08:30:36 1991 Fred Fish (fnf at cygnus.com)
+
+ * dwarfread.c (enum_type, struct_type): Fixes for opaque and
+ anonymous enumerations, structures, and unions. Now passes all
+ the current gdb test suite tests.
+
+Thu Dec 5 22:46:13 1991 K. Richard Pixley (rich at rtl.cygnus.com)
+
+ * Makefile.in: idestdir and ddestdir go away. Added copyrights
+ and shift gpl to v2. Added ChangeLog if it didn't exist. docdir
+ and mandir now keyed off datadir by default.
+
+Thu Dec 5 21:53:21 1991 John Gilmore (gnu at cygnus.com)
+
+ * symtab.c (decode_line_1): If SKIP_PROLOGUE leaves us in
+ mid-line, be more careful about possibly advancing to the next line.
+
+Thu Dec 5 18:59:51 1991 Michael Tiemann (tiemann at cygnus.com)
+
+ * cplus-dem.c (cplus_demangle): Call `string_need' when
+ null-terminating a partially-computed string.
+
+Thu Dec 5 18:19:43 1991 Fred Fish (fnf at cygnus.com)
+
+ * dwarfread.c (enum_type): Build a correct TYPE_NAME, add a
+ symbol to the symbol table for each member of the enum.
+
+ * dwarfread.c (struct_type): Build a correct TYPE_NAME.
+
+ * dwarfread.c (add_enum_psymbol): New function to extract enum
+ member names and add them to the partial symbol table while
+ building partial symbol tables.
+
+Thu Dec 5 17:31:05 1991 John Gilmore (gnu at cygnus.com)
+
+ * symtab.c (check_stub_method): Must allocate two extra argument
+ slots (one for `this', one for arglist terminator).
+
+Thu Dec 5 10:51:05 1991 Fred Fish (fnf at cygnus.com)
+
+ * inflow.c (child_terminal_info): Supply missing '"' character.
+
+ * buildsym.c (define_symbol): Supply missing parenthesis.
+
+Thu Dec 5 03:34:21 1991 John Gilmore (gnu at cygnus.com)
+
+ * coredep.c (fetch_core_registers): Fencepost error. Fixed by
+ Jay Lepreau <lepreau@cs.utah.edu>.
+
+ * inflow.c: Remember whether GDB has a terminal. Avoid switching
+ terminals back and forth if we don't have one.
+
+ * c-exp.y (parse_number): Zero is not an unsigned int constant!
+ * dbxread.c (read_dbx_symtab): Enum type numbers can be in (1,2) form.
+
+ Improve type parsing.
+ * buildsym.c (define_symbol, read_range_type): Add
+ long_kludge_name that passes the names of range types being
+ defined, down to where we must choose between 'int' and 'long'
+ variants. This fails on Sun C anyway since the compiler itself is
+ confused between int and long.
+ (read_array_type, cleanup_undefined_types): Correct the size of
+ array type whose element-type size isn't immediately known.
+
+ Early preparation to blow away many builtin types, building them
+ on the fly as needed. Don't compare types to builtin types with
+ ==; examine the relevant fields instead.
+ * coffread.c (process_coff_symbol: C_ARG, C_REGPARM): Avoid ==.
+ * buildsym.c (define_symbol, case 'p'): Avoid ==.
+ * valops.c (value_arg_coerce): Avoid ==. Don't assume host and
+ target types are the same.
+ * valprint.c (val_print): I finally understand arrays, remove FIXME.
+
+ * symmisc.c (printpsyms_command): Reduce redundancy, and put all
+ addresses in GDB itself into parens for easy cleanup and diffing.
+
+Wed Dec 4 21:05:30 1991 Fred Fish (fnf at cygnus.com)
+
+ * dwarfread (enum_type): Arrange for the order of enumeration
+ members to match the source code order; not the order in the
+ Dwarf information, which is explicitly reverse order.
+
+Wed Dec 4 18:24:39 1991 John Gilmore (gnu at cygnus.com)
+
+ * main.c (input_from_terminal_p): Check whether GDB has a
+ terminal at all.
+ (initialize_main): Revise doc for `set editing'.
+
+Wed Dec 4 15:36:39 1991 Fred Fish (fnf at cygnus.com)
+
+ * dwarfread.c (struct_type): Handle structures and unions which
+ contain DIE's other than just member dies.
+
+Wed Dec 4 01:59:05 1991 John Gilmore (gnu at cygnus.com)
+
+ * symfile.c (reread_symbols): Avoid kludging mtime_set, now that
+ BFD is fixed.
+
+Tue Dec 3 17:24:57 1991 John Gilmore (gnu at cygnus.com)
+
+ * Makefile.in: VERSION 4.2.96.
+
+ * main.c (initialize_main): Revise command descriptions.
+ * command.c (show_user): `info user' -> `show user'.
+ * symtab.c (_initialize_symtab): Typo in `info types' desc.
+
+ * coffread.c (coff_symfile_read): Avoid select_source_symtab,
+ since it is not needed and can cause errors when examining ".o"s.
+ (read_coff_symtab, decode_base_type): Use complain, not printf.
+ Print symbol name, not its number.
+ Remove "#if defined(clipper) #define BELIEVE_PCC_PROMOTION", which
+ someday should go in a clipper target config file.
+
+ * symfile.c (compact_misc_function_vector): Handle empty vector.
+ (complain, clear_complaints, syms_from_objfile): Fix complaint
+ formatting.
+ * xcoffexec.c: Change syms_from_objfile caller.
+
+ * sparc-xdep.c: Force tm-file as tm-sparc.h, to make it compile
+ when configured for cross debugging. FIXME, this needs a more
+ general solution.
+
+Mon Dec 2 11:04:05 1991 Per Bothner (bothner at cygnus.com)
+
+ * mips-tdep.c (init_extra_frame_info): Float register
+ 'i' has gdb-internal number 'FP0+i', not '32+i'.
+ * mipsread.c (new_symbol): Translate g++ special
+ symbol "$t" to "this".
+
+Sat Nov 30 21:29:55 1991 Steve Chamberlain (sac at cygnus.com)
+ Changes due to include file renaming:
+
+ * xcoffread.c: internalcoff.h ->coff/internal.c,
+ coff-rs6000.h ->coff/rs6000.h
+ * mipsread.c: coff-mips.h ->coff/mips.h
+ * elfread.c: elf-common.h ->elf/common.h
+ elf-external.h ->elf/external.h,

+ * dbxread.c: aout64.h ->aout/aout64.h
+ stab.gnu.h ->aout/stab_gnu.h
+
+ * coffread.c: internalcoff.h ->coff/internal.h
+ * buildsym.c: stab.gnu.h ->aout/stab_gnu.h
+ * depend Updated to take the above into account.
+
+Fri Nov 29 16:59:25 1991 Fred Fish (fnf at cygnus.com)
+
+ * configure.in: Add SVR4 i386 configurations.
+

+ New files for i386/SVR4.
+
+ * tm-i386v.h: Allow START_INFERIOR_TRAPS_EXPECTED and
+ DECR_PC_AFTER_BREAK to be predefined by files including
+ tm-i386v.h.
+
+ * i386-tdep.c: Add supply_gregset(), fill_gregset(),
+ supply_fpregset(), and fill_fpregset() functions, which are
+ target dependent support functions for the SVR4 /proc register
+ interface.
+
+ * dwarfread.c (enum_type, struct_type): Expand recognized
+ compiler generated tags to include symbols beginning with '.' as
+ well as '~'.
+
+ * symtab.c (sources_info): Change simple printf of error message

+ print a message if any of them fail.
+ (terminal_ours_1): Store result of ioctl's for debugging, but
+ don't print (the terminal isn't ours...).
+
+ * tm-tahoe.h (FRAME_ARGS_ADDRESS): No need to offset from frame
+ pointer.
+
+ * m2-exp.y (MAX, MIN): Rename to MAX_FUNC, MIN_FUNC to avoid
+ conflicts with system header files.
+
+Fri Nov 22 08:27:40 1991 John Gilmore (gnu at cygnus.com)
+
+ * Roll VERSION to 4.2.95.

+
+ * infptrace.c, tm-sun386.h: Cashier <a.out.gnu.h>, remove refs.
+
+ * configure.in, xconfig, tconfig, Makefile.in, doc/gdbint.texinfo:
+ Makefile fragments for various hosts and targets now come from
+ gdb/config/mh-* and gdb/config/mt-*. This is for consistency with
+ other config setups.
+
+ * rs6000-pinsn.c, rs6k-opcode.h: Clean up.
+ * rs6k-opcode.def: Delete.

+
+ * dwarfread.c (enum_type, struct_type): Ignore names invented by
+ helpful compilers for anonymous structs, unions, and enums.
+
+ * c-exp.y, m2-exp.y: Add defines for yymaxdepth, yy_yys, and
+ yy_yyv, so multiple parsers produced by SVR4 versions of yacc
+ can coexist in the same executable without collision.
+
+ * symtab.h: Add declaration for lookup_template_type() to kill
+ compiler warnings about conversions from int to pointer.
+
+Mon Nov 18 17:45:18 1991 Fred Fish (fnf at cygnus.com)
+
+ * procfs.c: Move inclusion of defs.h to before param.h, as in
+ all the other source files that include both. This is required
+ to supply some typedefs that are used in files included by param.h.
+
+ * m68k-tdep.c (m68k_skip_prologue): Add generic m68k support for
+ skipping function prologues, ala the other cpu families (i386,

+Mon Nov 18 13:51:37 1991 Per Bothner (bothner at cygnus.com)
+
+ * source.c (open_source_file): If openp fails, try again
+ using just the base (non-directory) part of the filename.
+ This solves various annoying problems, such as when the
+ source was compiled with an absolute pathname - and the
+ source files have moved. Or if the source was compiled
+ using a relative pathname, it can be more convenient
+ to just specific the source directory to the dir command.
+

+
+ * cplus-dem.c (munge_function_name): Add missing third arg to

+ TYPE_CPLUS_SPECIFIC unless TYPE is TYPE_CODE_STRUCT.
+ * buildsym.c (read_type): Allocate TYPE_CPLUS_SPECIFIC for
+ TYPE_CODE_STRUCT.
+ (read_struct_type): Ditto. Also, add comments about how we can

+ remove duplicate misc function vector entries. See comments
+ in source for why this is necessary/desirable.
+

+ record_misc_function(). Remove calls to init_misc_bunches()
+ and condense_misc_bunches(), these are now done in elfread.c.
+
+ * elfread.c: Add support for reading bfd canonical symbol tables
+ and generating misc function vector entries for global and
+ absolute symbols. Do calls to init_misc_bunches() and
+ condense_misc_bunches() where they will enclose all calls to
+ record_misc_function(), including those in dwarfread.c.
+
+Thu Nov 14 17:02:11 1991 Roland H. Pesch (pesch at cygnus.com)
+

+ from i960-tdep.c and adapt to the function prologues on the 88k.
+ (read_next_frame_reg): Borrow from mips-tdep.c.
+ FIXME: frame_locals_address should go away.
+
+ * tm-delta88.h: Dump all the tdesc stuff.
+ Macros for all frame-related stuff call fns of same name.

+
+ Allow setting breakpoints on C++ destructors.
+ * valops.c (destructor_name_p): Don't check TYPE_HAS_DESTRUCTOR,

+ flags since they are no longer used.

+ * eval.c (parse_and_eval_type), value.h: New function,
+ parse_and_eval_type, is based on old code from check_stub_method.
+ But don't actually evaluate the cast, since that calls
+ value_cast(), whcih may fail. Just extract the type
+ from the parsed expression.
+ * values.c (check_stub_method): While looping through the
+ arguments, adjust depth *after* parameter has been handled.
+ Replace call and setup of parse_and_eval with new function
+ parse_and_eval_type.
+
+Tue Nov 12 09:40:07 1991 Fred Fish (fnf at cygnus.com)

+
+ Add tracking of object files (that contain symbols) to gdb.
+ This includes a "struct objfile" that owns symtabs and psymtabs
+ that were read in from that binary file.
+
+ * symfile.h: Add struct objfile. Add pointer to the objfile
+ into the struct sym_fns.

+
+Thu Nov 7 18:26:15 1991 Steve Chamberlain (sac at rtl.cygnus.com)
+
+ * Makefile.in: link with libiberty after libreadline, since
+ readline might want something in libiberty.
+ * m88k-xdep.c: Fixed the register offsets in the ptrace_user
+ struct for BCS 88k machines.
+ * xm-m88k.h: don't define USIZE if already defined.
+ * configure.in: Added delta88 target.
+
+Thu Nov 7 04:51:19 1991 John Gilmore (gnu at cygnus.com)
+
+ * am29k-pinsn.c, am29k-opcode.h: Fix decoding of mtacc, dmac, fmac.
+
+ * tm-*.h: Remove READ_DBX_FORMAT, COFF_FORMAT, and

+
+Wed Nov 6 02:54:08 1991 Steve Chamberlain (sac at cygnus.com)
+
+ * coffread.c (read_coff_symtab): coffread used to rely on the
+ x_sym.x_misc.x_lnsz.x_lnno field giving the # of linnos in a
+ function. Two of the formats I'm using (29k and 88k) don't seem to
+ set it. Ths patch to fcn_last_line and (enter_linenos) is an
+ attempt to use the actual size of the linno table in the file to set
+ the number of linenos to process.
+
+Tue Nov 5 22:47:46 1991 Steve Chamberlain (sac at cygnus.com)
+
+ * Makefile.in: put a - infront of the mv y.tab.c c-exp.tab.c and
+ mv y.tab.c m2-exp.tab.c, so that if bison is used, and the files

+ * language.c: Add case branches for C++ (currently, all
+ the same as C). Also, add c++ to "usage" note for "set lang".
+ * valprint.c (typedef_print). Add case branches for C++.
+ * main.c (main): New way to set initial language: Look at
+ file extension of psymtab containing main(). (Same as we
+ do for symtabs, but avoid loading the symtab yet.)
+ * symtab.c: New routine find_main_psymtab(), used by main()
+ to set initial language.
+ * symfile.c (allocate_symtab): Move code for mapping file
+ extensions-> languages to new deduce_language_from_filename().
+
+ Fix a C++ problem when looking for methods in super-classes.
+ There was confusion between base and derived types.
+ * valops.c (value_fn_field): Change function interface.
+ * values.c: Use new value_fn_field interface.
+
+Mon Nov 4 10:49:33 1991 Per Bothner (bothner at cygnus.com)
+
+ * infrun.c: Fixed typo in comment.
+ * utils.c: All the v*fprintf emulation is now in libiberty,
+ so we can get rid of some junk.
+ * xm-sun3os4.h, xm-sun4os4.h, xconfig/decstation, xconfig/i386sco,
+ xconfig/sun3os4, xconfig/sun4os4: Don`t need HAVE_STRSTR any more.
+ * m68k-pinsn.c (print_insn_arg): Support BB/BW/BL
+ type operands, as used by branch instructions.
+ * gmalloc.c: Fix prototype of memcpy.
+ * elfread.c: Comment out register_addr, since it conflicts
+ with the one in coredep.c.
+ * buildsym.h: Remove extern declarations of two functions
+ that are really static in buildsym.c.
+ * tm-mips.h: Add symbolic names for more registers.
+ * mips-xdep.c (store_inferior_registers): Use new register names.
+ * xm-mips.h: Simplify REGISTER_U_ADDR, since it is now
+ only used for core files, not ptrace. Therefore,
+ the KERNEL_U_ADDR hack is no longer needed.
+ The mapping to ptrace number is now in in mips-xdep.c.
+ * mips-xdep.c: Define REGISTER_PTRACE_ADDR (using the
+ mapping from the old REGISTER_U_ADDR), and use it
+ in {fetch,store}_inferior_registers.
+ * mipsread.c: Rename #include ecoff.h to new name coff-mips.h.
+ * mips-tdep.c (mips_push_dummy_frame, mips_pop_frame):
+ Save/restore FP regs correctly (?).
+ * dbxread.c: Remove duplicate define_symbol and type_synonym_name
+ (these had been previously moved to buildsym.c).
+ Hence, define_symbol becomes extern instead of static.
+ * buildsym.c (read_struct_type): Comment out bogus handling
+ of C++ operator methods. Minor hacking of reading of class
+ contexts. Make define_symbol non-static, so dbxread.c can call it.
+
+Fri Nov 1 11:05:47 1991 John Gilmore (gnu at cygnus.com)
+
+ * mipsread.c (read_mips_symtab, read_the_mips_symtab): Use real
+ filename with error messages.
+ * stack.c (frame_select_command): Rename to select_frame_command
+ to avoid "fr" and "fra" having nonunique completions.
+ * symfile.c (sort_symtab_syms): Ignore sort of zero symtab *.
+ (symfile_init): Print file format name when unable to handle it.
+ (free_named_symtabs): Use BLOCKVECTOR rather than obsolete BLOCKLIST.
+ * symmisc.c (free_symtab): Only free linetable if nonzero.
+ * symtab.h: Remove obsolete BLOCKLIST macros.
+
+Thu Oct 31 18:12:43 1991 Stu Grossman (grossman at cygnus.com)
+
+ * infrun.c (wait_for_inferior): another stepi/nexti fix. Ensure
+ that stop_step is 1 at bottom of main loop. I don't know why this
+ needs to be done, but it helps me sleep better at night.
+
+Sun Oct 27 18:18:39 1991 Stu Grossman (grossman at cygnus.com)
+
+ * main.c (initialize_history): Read history after reading all
+ init files.
+
+Sun Oct 27 14:09:25 1991 John Gilmore (gnu at cygnus.com)
+
+ * buildsym.c: Break out initial malloc sizes.
+ (record_line): Record directly in a subfile. Alloc on demand.
+ (compare_line_numbers): Add from xcoffread.c.
+ (end_symtab): New params say whether to sort pendings and
+ linetable. Patch block stabs if defined. Shrink linetable before
+ allocating the symtab.
+ * buildsym.h: Delete line_vector* and prev_line_number. Add
+ global_stabs and file_stabs for xcoffread.
+ * dbxread.c (start_subfile): Move to buildsym. Change above calls.
+ * symtab.h: LINETABLE(symtab) can now be null. Zap LINELIST.
+ * symmisc.c, symtab.c: Cope with null LINETABLEs.
+
+ * blockframe.c: Pass fromleaf to INIT_EXTRA_FRAME_INFO.
+ * tm-29k.h, tm-88k.h, tm-i960.h, tm-irix3.h, tm-mips.h, tm-pyr.h,
+ tm-sparc.h: Accept fromleaf parameter.
+ * c-exp.y (yyerror): Pass error message if given.
+ * configure.in: Add rs6000 host and target.
+ * inflow.c (new_tty): O_NOCTTY kludge for RS/6000.
+ * symfile.h (entry_point): Add.
+
+Sat Oct 26 00:16:32 1991 John Gilmore (gnu at cygus.com)
+
+ * buildsym.c: New file. Breaks out symbol-table-building routines
+ from dbxread.c, so they can be shared with xcoffread.c.
+ * buildsym.h: New file. Declarations for buildsym.c users.
+ * dbxread.c: Remove large chunks into buildsym.c.
+ * Makefile.in: Add buildsym.c and buildsym.h.
+
+ * symfile.c (syms_from_bfd): New routine.
+ (add_symbol_file): Call it to do the real work.
+ (syms_from_bfd): Initialize entry_point before calling symfile_init.
+ * symtab.h, symfile.c, coffread.c, mipsread.c, dwarfread.c:
+ Avoid declaring or setting entry_point (symfile.h & symfile.c cope).
+
+Fri Oct 25 10:58:16 1991 Mark Eichin (eichin at cygnus.com)
+
+ * cplus-dem.c (cplus-demangle): added support for templates, static
+ data, and the new (correct) mangling for destructors.
+
+ * dwarfread.c: (dwarfwarn): created a varargs version of
+ dwarfwarn, for non __STDC__ compilers.
+
+ * c-exp.y: (yylex): added match for "template" token.
+ (typebase): added TEMPLATE name '<' type '>' clause, for explicit
+ specification of template types.
+
+ * symtab.c: (lookup_template_type): new function for finding
+ templates in symbol table.
+ (type_name_no_tag): changed to explicitly check for s/u/e at the
+ beginning of the symbol - if it is a template, none of these will
+ be there (but the name will still contain spaces.)
+
+Fri Oct 25 18:59:32 1991 Per Bothner (bothner at cygnus.com)
+
+ Various fixes to improve g++ debugging.
+ * symtab.h: Add is_const and is_volatile flags for each method.
+ These are bit fields - take their space from voffset,
+ which shrinks to 30 bits. Since voffset is now a bitfield,
+ make it unsigned for portability. This changes its interpretation
+ slightly: Static methods now have voffset 1 instead of -1,
+ and virtual offsets start at 2, not 1.
+ * symtab.c: Renamed gdb_mangle_typename to gdb_mangle_name,
+ since it now returns an entire magled method name, not just
+ the type part. This avoids some duplication.
+ It also allows us to correctly mangle const and volatile
+ methods (using the new is_const and is_volatile bit fields
+ mentioned above).
+ * valprint.c (type_print_base), values.c (check_stub_method):
+ Simplify by using new gdb_mangle_name.
+ * values.c (value_headof): Fix to correctly handle single
+ inheritance (actually two fixes, either of which suffices).
+ * dbxread.c (read_struct_type): Handle const and volatile
+ method specifiers.
+ * dbxread.c (read_struct_type): Yet one more place where
+ we must handle '\\' continuations.
+ * valprint.c (vtbl_ptr_name): Add final '\0'.
+
+Fri Oct 25 16:06:38 1991 Stu Grossman (grossman at cygnus.com)
+
+ * tm-sparc.h, tm-68k.h (EXTRACT_RETURN_VALUE): fix output of
+ short return values for sparc and 68k. Patch from Paul Eggert.
+
+ * coffread.c, coredep.c, i386-xdep.c: install patches for
+ SysV/386 3.2 from Mauro DePalma.
+
+Fri Oct 25 02:02:13 1991 John Gilmore (gnu at cygnus.com)
+
+ * core.c (core_file_info), exec.c (exec_file_info): Print file
+ type. Use printf_filtered.
+
+ * valops.c (value_fetch_lazy): Avoid 0-length fetches.
+
+Thu Oct 24 23:06:40 1991 Fred Fish (fnf at cygnus.com)
+
+ * dwarfread.c: Add casts to remove compiler warnings.
+
+ * tm-3b1.h, tm-68k.h, tm-altos.h, tm-amix.h, tm-hp300bsd.h,
+ tm-hp300hpux.h, tm-isi.h, tm-news.h, tm-pn.h, tm-sun2.h,
+ tm-sun3.h: Remove locally duplicated code for calling functions
+ in the inferior. The only differences were in the specific trap
+ vectors used and whether or not an fpu was present. These are
+ now handled by appropriate definitions of BPT_VECTOR and
+ HAVE_68881 respectively. Other minor obvious cleanups.
+
+ * valops.c: Correct a minor misspelling.
+
+ * utils.c: Remove local BSD/USG hacks that are now in libiberty.
+
+ * dwarfread.c: Remove prototype for dwarfwarn. Does not work
+ with <varargs.h>.
+
+Thu Oct 24 09:33:44 1991 John Gilmore (gnu at cygnus.com)
+
+ * stack.c (frame_command): Always print. Use new
+ frame_select_command to select a frame without printing.
+
+ * dwarfread.c: Use <varargs.h>, since <stdarg.h> is not portable.
+
+Thu Oct 24 01:32:51 1991 Fred Fish (fnf at cygnus.com)
+
+ * dwarfread.c: New file for DWARF debugging format support.
+
+ * elfread.c: New file for ELF object file format support.
+
+ * procfs.c: New file for SVR4 /proc (process file system) support.
+
+ * tm-amix.h, xm-amix.h, tconfig/amix, xconfig/amix: New files for
+ Amiga UNIX support.
+
+ * xm-svr4.h, tm-svr4.h: New files for SVR4 support.
+
+ * xm-m68k.h: New file for host machines with m68k cpu.
+
+ * Makefile.in: Add elfread.c and dwarfread.c to SFILES_MAINDIR.
+ Add elfread.o and dwarfread.o to OBS.
+
+ * symfile.h: Add "elf" to list of supported formats in comment.
+
+ * c-exp.y, defs.h, symtab.h, valprint.c: Add three new builtin
+ types to gdb, builtin_type_long_double, builtin_type_complex, and
+ builtin_type_double_complex. Add and use new TARGET_SHORT_BIT,
+ TARGET_INT_BIT, TARGET_LONG_BIT, TARGET_FLOAT_BIT,
+ TARGET_DOUBLE_BIT, TARGET_LONG_DOUBLE_BIT, TARGET_COMPLEX_BIT, and
+ TARGET_DOUBLE_COMPLEX_BIT, as the sizes in bits of the indicated
+ types on the target machine (ala the existing TARGET_LONG_LONG_BIT).
+
+ * infrun.c: When using SVR4 /proc interface instead of ptrace(),
+ call proc_set_exec_trap() to setup child to stop at first instruction.
+
+ * inftarg.c: When using SVR4 /proc interface, call proc_wait()
+ rather than wait().
+
+ * m68k-tdep.c: Add new routines supply_gregset(), fill_gregset(),
+ supply_fpregset(), and fill_fpregset(), which are machine
+ dependent support routines for SVR4 /proc interface.
+
+ * utils.c: Add warning_setup() and warning(). Warning() behaves
+ the same as error() except that it returns normally rather than
+ jumping back to command level. Modules that don't want to call
+ warning() for some reason, but want to produce their own warnings,
+ can call warning_setup() to ensure compatibility with the way
+ warning() and error() deal with the terminal.
+
+ * symtab.c: Make internal errors produce more useful messages.
+
+ * tm-68k.h: Move code that is duplicated in almost every single
+ m68k based machine's configuration files to this common file.
+ Duplications in the configuration files still need to be removed
+ (FIXME).
+
+ * infrun.c (child_create_inferior): System V versions must call
+ setpgrp() with no arguments, to comply with prototyping typically
+ in <unistd.h>.
+
+ * munch: Add support for SVR4 style nm output.
+
+ * dbxread.c, mipsread.c symmisc.c, symtab.c: Remove the object
+ file specific fields from the partial symbol table structure and
+ replace them with a pointer to private data for each different
+ flavor of object file reader to initialize appropriately.
+
+Wed Oct 23 09:38:20 1991 John Gilmore (gnu at cygnus.com)
+
+ * xconfig/sun[34]os4: Add note about strstr botch on sunos4.0.3c
+ and previous.
+
+ * mipsread.c (fixup_undef_type): New function. If a struct /
+ union / enum is defined in a header file but nowhere else used,
+ (by typedefing, pointer referencing or declaration) the mipsread code
+ builds the complete tree for the structure but leaves its code as
+ TYPE_CODE_UNDEF as it doesn't know what kind of aggregate it is.
+ Guess its type based on the details of the members.
+
+Tue Oct 22 18:04:32 1991 Stu Grossman (grossman at cygnus.com)
+
+ * infrun.c (wait_for_inferior): Check return value from
+ find_pc_line.
+
+Mon Oct 21 17:47:03 1991 Stu Grossman (grossman at cygnus.com)
+
+ * infrun.c (wait_for_inferior): fix stepi/nexti that was broken
+ by my last edit to this routine.
+
+Mon Oct 21 14:27:43 1991 John Gilmore (gnu at cygnus.com)
+
+ * tm-sun3.h (FIX_CALL_DUMMY): problem with cross debugging.
+ FIX_CALL_DUMMY does unaligned accesses and/or forgets to byte swap
+ the values before putting them into the dummy code. (From Peter
+ Schauer)
+
+Mon Oct 21 10:04:39 1991 Steve Chamberlain (steve at rtl.cygnus.com)
+
+ * configure.in: added ebmon target.
+
+Wed Oct 16 22:49:58 1991 John Gilmore (gnu at cygnus.com)

+ * coredep.c (fetch_core_registers): Take new argument, use it,
+ and pass it to register_addr to locate the block of registers.
+ * xm-mips.h: Update KERNEL_U_ADDR for new scheme. Cleanup a bit.
+
+ * dbxread.c (read_dbx_symtab, process_one_symbol): Handle
+ Sequent N_FN_SEQ like everybody else's N_FN.
+
+ * main.c: Circumvent SCO cc bug with #if !!defined(USG).

+
+Thu Oct 10 17:25:47 1991 John Gilmore (gnu at cygnus.com)

+Wed Oct 9 17:03:34 1991 John Gilmore (gnu at cygnus.com)
+

+ This avoids coredumps under `set print object on' in value_headof
+ (called erroneously by value_from_vtable_info) for `p &struct'
+ or `p *struct'. From Peter Schauer.
+
+Mon Oct 7 00:06:52 1991 John Gilmore (gnu at cygnus.com)
+
+ * Makefile.in: Roll version to 4.1.2.
+ * dbxread.c: Use aout64.h, not a.out.gnu.h. Get external symbol entry
+ size from BFD (but, FIXME, we don't yet read external nlists's and
+ convert them to internal nlists's before handling them -- we still
+ assume they have the same size and alignment.) Use SET_NAMESTRING
+ everywhere useful.
+ * exec.c (exec_file_command): Move dead coff-encapsulation code
+ to BFD.
+ * m88k-tdep.c, m88k-xdep.c: Remove encap test and #inc <a.out.h>.

+
+ * coffread.c, dbxread.c, symfile.c, symmisc.c, symtab.h: Remove
+ vestiges of typevectors, which were for symsegs and are no longer
+ used. (From a question by Eliot Dresselhaus
+ <dresselh@RFT30.nas.nasa.gov>).
+
+Thu Oct 3 09:33:26 1991 John Gilmore (gnu at cygnus.com)
+
+ * dbxread.c, coffread.c: static-ize functions that were
+ gratuitiously external. (From Fred Fish.)
+
+ * c-exp.y: sym->class to SYMBOL_CLASS (sym).
+
+ * dbxread.c (dbx_lookup_type): Keep doubling size of typevector

+
+Tue Oct 1 06:33:55 1991 John Gilmore (gnu at cygnus.com)
+
+ * symtab.c (lookup_symtab_1, lookup_symbol): "fatal" errors
+ between symtabs and psymtabs become ordinary error()s.
+
+ * dbxread.c (read_dbx_symtab): Relocate end_of_text_addr
+ properly, making "end pc" correct in shared lib psymtabs.
+ (From Guy Harris <guy@auspex.com>.)
+
+Mon Sep 30 13:15:31 1991 John Gilmore (gnu at cygnus.com)
+
+ * dbxread.c: Enable, but soften, const_vol_complaint.
+ (read_dbx_symtab): N_STSYM and N_LCSYM define static vars.
+ Ditto Gould N_NBSTS and N_NBLCS. Also, all types in the psymtab
+ should be file-scope, not global.
+ (read_struct_type): Remove ancient multiple-inheritance warning.
+ (read_range_type): Check base type, complain & patch if undefined.
+ * stack.c (frame_info): Demangle the function name in `info stack'.
+ (From Peter Schauer)
+
+Sat Sep 28 10:02:33 1991 John Gilmore (gnu at cygnus.com)
+
+ * eval.c (evaluate_subexp_for_address): Don't use
+ TYPE_POINTER_TYPE directly (it might be zero if this type has
+ never had a pointer created before); use lookup_pointer_type.
+ * symtab.c (lookup_method_type): Arguments were swapped in all
+ callers, so fix it here. I'm amazed this worked at all!
+
+Fri Sep 27 18:09:31 1991 John Gilmore (gnu at cygnus.com)
+
+ * c-exp.y, m2-exp.y: Define more yysymbols that happen to be

+ (Reported by Mark Peek <mark@imagen.com>.)
+
+ * solib.c (solib_map_sections): Relocate all sections, even

+ for eventual elimination as we generalize to N sections.
+
+ * infrun.c (wait_for_inferior): Don't check if the PC is in a
+ call_dummy if we were stopped by a random signal that is being
+ passed to the program. This produced wierd results when calling
+ functions in the inferior and signals (e.g. SIGALRM) were in use.
+
+Tue Sep 24 18:05:30 1991 John Gilmore (gnu at cygnus.com)
+

+Fri Sep 20 17:39:14 1991 Roland H. Pesch (pesch at cygnus.com)
+
+ * doc/gdb.texinfo: Updates from ChangeLog. set/show write,
+ autoloading shared libs, copyright etc on GDB startup, clean up $_
+ and $__ index refs, set/show listsize and related updates to list
+ cmd. New host/target configs.
+
+Fri Sep 20 15:46:00 1991 Roland H. Pesch (pesch at cygnus.com)
+
+ * doc/Makefile: generate aux version-no file doc/gdbVN.m4
+ from main Makefile.in version definition
+ doc/gdb.texinfo: use version recorded in doc/gdbVN.m4 for current
+ GDB version no refs
+ Makefile.in (setup-to-dist): generate doc/gdbVN.m4
+
+ * doc/gdb.texinfo: merge new language-switching and lang-specific
+ doc by Andrew Beers
+
+Fri Sep 20 15:00:57 1991 Per Bothner (bothner at cygnus.com)
+
+ * mcheck.c: Add __ONEFILE kludge to allow compilation by non-ANSI
+ compilers (which may lack stddef.h).
+
+Fri Sep 20 13:29:42 1991 John Gilmore (gnu at cygnus.com)
+
+ * dbxread.c (read_dbx_symtab, process_one_symbol): N_FN and
+ N_WARNING are the same except for the N_EXT bit, so just use their
+ values alone, rather than OR-ing them with N_EXT.
+
+Fri Sep 20 12:27:55 1991 Stu Grossman (grossman at cygnus.com)
+
+ * mipsread.c (parse_lines): Deal with negative extended line
+ offsets correctly.
+
+ * c-exp.y, m2-exp.y: #define yyerrflag and yynerrs to avoid
+ global symbol conflicts.
+
+Fri Sep 20 02:28:15 1991 John Gilmore (gnu at cygnus.com)
+
+ * .gdbinit: Move 'set complaints' to top, so it runs even in
+ case we aren't debugging GDB.
+ * language.c (_initialize_language): Fix type check and range
+ check documentation strings.
+ * utils.c (!HAVE_VPRINTF): Define vfprintf as a function, so
+ language.c can use it. (Though language.c should really not be
+ handling warnings/errors the way it does, FIXME.)
+ * symtab.c (lookup_primitive_type): const lint.
+
+ Bugfix from Peter Schauer:
+ * source.c (lines_to_list): Make signed, to avoid comparison
+ going unsigned and complaining that -3 is too high for 21 lines.
+ * stack.c (lines_to_list): Ditto.
+
+Thu Sep 19 23:33:41 1991 John Gilmore (gnu at cygnus.com)
+
+ * Makefile.in (HFILES): Add minimon.h.
+ (VERSION): Roll version number to 4.0.95.
+ (gdb.tar.Z, make-proto-gdb.dir, setup-to-dist, gdb-XXX.tar.Z):
+ New rules for building distributions. Normal distribution
+ is built by doing `make -f Makefile.in gdb.tar.Z' in the directory
+ one level up from here; it calls make-proto-gdb.dir to build a
+ directory `proto-gdb' which is an image of the release. The old
+ `gdb.tar.Z' rule still works too.
+ * config.sub, configure: Roll in latest from ..
+
+Thu Sep 19 17:41:24 1991 Roland H. Pesch (pesch at cygnus.com)
+
+ * doc/gdbint.texinfo: Reorder contents; reorganize new-host,
+ new-target, and new-config chapters; fix minor typos; come closer
+ to usual GNU markup conventions for @file @samp @code @var.
+
+Thu Sep 19 17:04:12 1991 Per Bothner (bothner at cygnus.com)
+
+ Patches from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>:
+ * mipsread.c (parse_partial_symbols): Enter the name of all
+ structs/unions... into the psymtab so we can access them if the
+ symtab is not read in.
+ * mips-tdep.c: Remove some unneeded #includes.
+ * xconfig/dec3100: Add HAVE_STRSTR.
+
+Thu Sep 19 15:14:23 1991 John Gilmore (gnu at cygnus.com)
+
+ * Makefile.in: Circumvent Sun Make bug on *-exp.tab.o.
+ * c-exp.y, m2-exp.y: Lint.
+ * m2-exp.y: Avoid using yytname[] which is a Bison-ism.
+ * valprint.c (val_print_fields): Check for stub type.
+ * mipsread.c (_initialize_mipsread): Avoid using
+ builtin_type_void at initialize time.
+ (mipscoff_symfile_read): use it now.
+
+Wed Sep 18 15:55:51 1991 John Gilmore (gnu at cygnus.com)

+
+Tue Sep 17 08:37:41 1991 John Gilmore (gnu at cygint.cygnus.com)
+
+ Add Andrew Beers' changes for Modula-2 support. His ChangeLog
+ entries are enclosed herein. Not all of these changes
+ have been merged into the master GDB sources -- check the
+ ChangeLog above here for the merge log.
+
+Mon Jun 3 17:05:45 EDT 1991
+
+ m2-exp.y Created. Tested outside of GDB for a few days. Proper
+ operators were added, C specific operators and tokens
+ removed. yylex() revamped to some extent. Still things
+ missing from the grammar, such as sets.
+ Tested for two weeks in GDB v3.5.
+
+Tue Jun 11 17:23:48 EDT 1991
+
+ m2-exp.y Added boolean constants TRUE and FALSE to the grammar
+ so they are built-in. Sort of a hack.
+
+Fri Jun 14 12:53:51 EDT 1991
+
+ m2-exp.y Added range checking for numeric constants. Any numeric
+ constant is assumed to be of builtin type INTEGER unless:
+ (1) it is octal or hexadecimal, in which case it is a
+ CARDINAL; (2) it is too big to fit into an INTEGER, in
+ which case it is a CARDINAL.
+ eval.c Added simple range checking for +, -, and * on integers.
+ Doesn't work very well for *, since 6 * 1,000,000,000 =
+ 1,705,032,704, which fails the simple test of result >=
+ first_operand, no matter in what order the operands are.
+
+Tue Jun 18 14:11:30 EDT 1991
+
+ Broke the parser into parts, one containing the C grammar and the other
+ containing code to be shared by all of the grammars.
+
+ The following files no longer exist:
+
+ expread.y
+ expread.tab.c
+
+ The following files were added:
+
+ c-exp.y (The C grammar)
+ m2-exp.y (The Modula-2 grammar)
+ parser-code.c (Code that is shared by the above grammar)
+ parser-code.h
+ parser-defs.h
+
+ Makefile.dist Changed to reflect the above dependencies. NOTE: It is
+ now necessary to use the Bison compiler compiler, since it
+ will generate function/variable prefixes other than yy.
+
+Tue Jun 18 16:47:49 EDT 1991
+
+ symtab.[ch] Added the external variable working_lang, than holds the
+ value of the current working language.
+ Added the ennumerated type language_mode, with the values
+ language_auto and language_manual, the former meaning that
+ GDB sets working_lang as needed, and the latter meaning
+ that the value of working_lang is totally under user
+ control.
+ symtab.[ch] Added the Modula-2 pervasive types INTEGER, CARDINAL,
+ REAL, BOOLEAN and CHAR. Also added the type codes
+ TYPE_CODE_BOOL and TYPE_CODE_CHAR.
+ utils.c Added set_language_command and show_language_command to
+ implement the GDB support commands "set language" and
+ "show language".
+ expression.h A number of identifiers were added to the type exp_opcode
+ to facilitate Modula-2 builtin functions, integer
+ division, and array indexing.
+
+Wed Jun 19 13:25:58 EDT 1991
+
+ language.h Added the macro STRICT_TYPE, which evaluates to non-zero
+ if the language specified by working_lang requires the use
+ of strict typing of expressions. Eventually, even this
+ will be able to be changed by the user.
+ Added the macro RANGE_CHECK, which evaluates to non-zero
+ if the language specified by working_lang requires the
+ checking of a value against the domain of its type.
+ Eventually, even this will be able to be changed by the
+ user.
+ language.[ch] Predicates involving types (simple_type, ordered_type,
+ same_type, integral_type, numeric_type, character_type,
+ boolean_type, float_type) are added. These predicates are
+ based on the current value of working_lang, and are handy
+ in type-checking.
+
+Wed Jun 19 15:39:34 EDT 1991
+
+ eval.c Added the function type_array_rank which computes the rank
+ of an array type.
+ valarith.c Added the funtion value_bool, which when given a integer
+ value.h value (ie. struct value *) as an argument, it returns a
+ boolean value (ie. struct value *) true if that integer
+ is non-zero, and a boolean value false otherwise.
+ valprint.c Added cases for TYPE_CODE_BOOL, so Modula-2 BOOLEAN values
+ will print out properly.
+
+Wed Jun 19 16:36:34 EDT 1991
+
+ valops.c Added the function value_capitalize, which returns it
+ value.h argument capitalized if its argument is a lowercase
+ letter, or the argument unchanged if its argument is not a
+ letter.
+ valarith.c Added the function range_check_p, which returns non-zero
+ value.h if its value argument is between the integral bounds upper
+ and lower.
+ Added the function range_check_enum_p, which makes sure
+ that its value argument is a valid member of the domain of
+ its type argument.
+ Added the function range_check_range_p, which makes sure
+ its value argument lies between the upper and lower bounds
+ of its type argument, which must be a ranged type.
+ Added the function check_array_index, which range and type
+ checks an index of an array.
+ Added the function value_multi_subscript, which computes
+ array[idx1,idx2...idxN], given a value array and an array
+ of values representing indicies.
+ values.c Changed value_from_long to work with TYPE_CODE_CHAR and
+ unpack_long to work with TYPE_CODE_BOOL and
+ TYPE_CODE_CHAR.
+
+Wed Jun 19 18:04:08 EDT 1991
+
+ symtab.c Stored pervasive types in a structure and make
+ lookup_pervasive_type() a lookup function that was based
+ on working_lang. If lookup_pervasive_type() returned
+ non-zero, then that value was returned (a fix, since
+ before it simply wouldn't return the pervasive type.)
+ language.h Added the macro CAST_IS_CONVERSION, which evaluates to
+ non-zero if the language specified by working_lang means
+ "conversion" when it says "cast".
+ valops.c Added the function value_real_cast(), which performs a
+ value.h *cast*, not a *conversion*, which is what value_cast()
+ does when it can. In particular,
+ value_cast(<float_type>,4) = 4.0, while
+ value_real_cast(<float_type>,4) = some mess.
+ eval.c Modula-2 builtin functions implemented: ABS, CAP, CHR,
+ parser-code.c FLOAT, HIGH, MAX, MIN, ODD, ORD, TRUNC, and VAL.
+ expression.h Added macros MAX_OF_TYPE and MIN_OF_TYPE to work with MAX
+ and MIN on integral types. *NOTE*: These are currently
+ hardcoded to work only if there are 8 bits per storage
+ unit. FIXME.
+ eval.c Made logical functions call value_bool to return a
+ properly typed boolean value, based on working_lang.
+
+Thu Jun 20 11:55:27 EDT 1991
+
+ valprint.c Types now print out in a Modula-2 fashion. This works for
+ the cases when the type is printed out step-by-step, that
+ is, it doesn't work when the name of a structured type
+ (which includes the keyword "struct", etc.) is simply
+ displayed.
+ FIXME: Perhaps this is bad. Parts of it seem to kludgey,
+ since type specifications in C and Modula-2 are very
+ different. The C printing of a type is very recursive,
+ whereas in Modula-2 it is generally very simple. C has
+ type prefixes and suffixes, which have no real analogue in
+ Modula-2. Maybe type_print() should call a language
+ specific type printer. This is also advantageous if we
+ compile GDB to exclude some of the languages. We'll just
+ leave those functions out.
+
+Thu Jun 20 16:57:10 EDT 1991
+
+ dbxread.c When reading the complete symbol table in (via
+ psymtab_to_symtab()), the number and types of function
+ arguments are added to a function type. define_symbol()
+ calls add_param_to_type() to accomplish this.
+ Assumption: when we come across a function definition
+ (N_FUN symbol with an 'f' or 'F' in the name), its
+ arguments will appear before another function definition.
+ When a function is found, a pointer to its type is placed
+ in the global in_function_type. Changes that
+ add_param_to_type() makes are to this global.
+ valprint.c The type of a function now includes (for Modula-2) the
+ types of its parameters.
+ eval.c Type checking and a check for the proper number of
+ arguments is now done for function calls. Not sure of the
+ impact this has on C++ member function yet.
+
+Thu Jun 20 19:58:48 EDT 1991
+
+ valprint.c Rewrote the type printer. Broke it into two language
+ specific parts, adding the functions type_print_m2() and
+ type_print_m2_1().
+ An unfortunate consequence is this: if you debugging a C
+ program in Modula-2 mode (why?), info types does not work
+ well with regular expressions, since the types are printed
+ out in Modula-2 terminology, but stored in C terminology.
+ language.[ch] Added the functions new_type_last(), type_keyword(), and
+ type_sep() to aid in the printing of typedefs.
+ symtab.c Made the printing of typedefs as language independent as
+ possible through calls to new_type_last(), type_keyword(),
+ and type_sep().
+
+Fri Jun 21 11:50:26 EDT 1991
+
+ dbxread.c Check all incoming ennumerated types. If it looks like
+ Modula-2's BOOLEAN type, then change the type_code of the
+ type to TYPE_CODE_BOOL so we can process it as a boolean
+ variable.
+ valprint.c Replaced some of the 0x%x with calls to sprintf and
+ hexformat() in val_print().
+ language.[ch] Added the function hex_to_string(), which converts its
+ integral argument to a hexadecimal number (format is
+ language based) and returns the result as a string.
+
+Mon Jun 24 12:25:07 EDT 1991
+
+ valprint.c Some functions call type_print_1() directly, instead of
+ value.h using type_print(), so they can specify where (column) to
+ print things. Since type_print() takes care of language
+ dependence, that needs to be called first. Added a
+ parameter depth to type_print() (so it is now like
+ type_print_1). Changed type_print to type_print_at, and
+ made type_print a macro that passes a depth argument of
+ zero.
+ symmisc.c Changed all calls to type_print_1 to calls to
+ type_print_at.
+ Makefile.dist Made it possible to build GDB for a specific set of
+ depend languages. Do this by passing a definition for the macro
+ LANGS to make. LANGS should be a string containing a
+ space-separated list of language names (ie. LANGS="c m2").
+ The default is to build all languages. Note that grammar
+ files must follow the naming convention of <lang>-exp.y.
+ gdb.lang This holds the current value of the LANGS macro. It is
+ examined every time make is called, and is updated if
+ necessary.
+ eval.c Added #ifdef _LANG_<lang> to these files.
+ expread.c Still need to add them to dbxread.c and coffread.c.
+ main.c
+ source.c
+ symtab.c
+ utils.c
+ valarith.c
+ valprint.c
+
+Mon Jun 24 16:33:11 EDT 1991
+
+ language.[ch] Added the functions hexformat_pre() and
+ hex_to_string_pre(), which take a prefix argument to
+ include in the format string. Thus, hexformat_pre("08") will
+ return "0x08x" (if the working language is language_c).
+ Made hexformat() and hex_to_string() calls to the above
+ with "" as the prefix argument.
+
+ am29k-pinsn.c, arm-pinsn.c, breakpoint.c, convex-tdep.c, exec.c, core.c,
+ dbxread.c, i386-pinsn.c, i386-stub.c, i386-xdep.c, i960-pinsn.c,
+ infcmd.c, inflow.c, m68k-pinsn.c, m68k-stub.c, m88k-pinsn.c,
+ mips-pinsn.c, mips-tdep.c, ns32k-pinsn.c, printcmd.c, pyr-pinsn.c,
+ pyr-tdep.c, pyr-xdep.c, remote-vx.c, remote.c, solib.c, source.c,
+ stack.c, sun386-xdep.c, symfile.c, symm-xdep.c, symmisc.c, tahoe-pinsn.c,
+ valprint.c, vax-pinsn.c
+
+ Changed all occurences of 0x%[0-9]*l*x in printf format strings to
+ calls to hexformat() and hex_to_string(). Format strings without
+ the leading "0x" were ignored.
+
+ depend Updated to take the above into account.
+
+
+Tue Jun 25 15:27:18 EDT 1991
+
+ symtab.h Added the types range_mode_t, range_check_t, type_mode_t,
+ and type_check_t to keep track of the current state of
+ range and type checking.
+ main.c Added the variables range_mode, range_check, type_mode,
+ and type_check to record the current state of range and
+ type checking. Added initialization code to main().
+ language.h Changed the macros STRICT_TYPE and RANGE_CHECK to examine
+ the above variables.
+
+
+Tue Jun 25 17:57:08 EDT 1991
+
+ dbxread.c process_one_symbol() updates the variable (enum language)
+ source_lang based on the extension of the filename
+ contained in the N_SO sybmol that started this symtab.
+ When end_symtab() is called, the value of source_lang is
+ put into the language field.
+ stack.c select_frame() sets working_lang (and possibly type_check
+ and range_check) to the language field of the symtab
+ associated with the frame that is selected if working_mode
+ is language_auto. If working_mode is language_manual, a
+ warning is printed and working_lang is not set.
+ language.c Added the function set_type_range(), which sets the value of
+ type_check and range_check (if their modes call for
+ automatic setting) based on the current value of
+ working_lang. A non-zero argument will cause the current
+ settings to be output.
+
+
+Wed Jun 26 14:51:40 EDT 1991
+
+ eval.c Added range checks on assignment.
+ m2-exp.y Added the grammar for sets to the language. Currently,
+ these do not do anything except print an error message.
+
+Wed Jun 26 17:01:04 EDT 1991
+
+ m2-exp.y Added the ability for parse_number() to parse negative
+ numbers. A global flag is set upon encountering a unary
+ minus. This was done to make, for example, 1 parse as a
+ CARDINAL, and not as an integer, per Wirth's examples in
+ Programming in Modula-2 ed.4.
+ valprint.c Added support for "set radix 2" by then setting
+ output_format to 't'.
+ eval.c Implemented range checking on subrange types. Added calls
+ to range_check_range_p for BINOP_ASSIGN and BINOP_VAL.
+ Implemented MIN and MAX for ennumerated types. The
+ minimum value of an ennumerated type is defined by Wirth
+ as the first identifier, and the maximum as the last.
+ m2-exp.y Made octal numbers ending with "B" be characters and those
+ ending with "C" be numbers, per Wirth's book. (p. 34)
+
+Thu Jun 27 14:11:52 EDT 1991
+
+ stack.c select_frame() now only sets working_lang, it does not
+ notify the user. If working_mode is language_manual, then
+ a warning is issued once.
+ main.c At the end of each call to execute_command(), working_lang
+ is checked against the local static (enum language)
+ current. If they differ and working_mode is
+ language_auto, the new settings of language, type and
+ range checking are printed out.
+ stack.c Modified frame_info() to include the language of the
+ current frame in the output of "info frame".
+ language.[ch] Added the function language_str() which returns the name
+ of the current language.
+
+Fri Jun 28 15:33:14 EDT 1991
+
+ m2-exp.y Added the built-in procedures INC, INCL, DEC, and DECL to
+ the language. INCL and DECL currently cause an error,
+ since sets are not implemented yet. INC and DEC are
+ implemented as PREINCREMENT/PREDECREMENT with one
+ argument, and as ASSIGN_MODIFY with two arguments.
+ eval.c Added type checking to the above cases.
+ value.h Added not_lval_constant to the lval_type ennumerated type.
+ not_lval_constant means that the value is a constant
+ value; that is 3 or 'a' or TRUE, not as in a constant
+ identifier. This is used to help coerce numbers such as 3
+ to either signed or unsigned numbers.
+ valops.c Added the function value_coerce_constants() which coerces
+ constant integers as following: if one is a constant and
+ the other is not, the constant's type is set to the type
+ of the other argument. If both are constants and one is
+ signed, the other is converted to a signed constant.
+
+Sat Jun 29 17:26:29 EDT 1991
+
+ valarith.c Added a better range checker. It now checks range
+ (successfully) on integral operations [+-] (signed and
+ unsigned) for any C sized type. Still does not work well
+ for multiplication.)
+ int_in_size() returns an integer that is coerced to fit into
+ specified number of bytes.
+
+Mon Jul 1 13:04:14 EDT 1991
+
+ language.[ch] Added the function binop_result_type(), which returns the
+ builtin (struct type *) type that would be the result of a
+ binop on the two values V1 and V2.
+
+Wed Jul 3 19:22:53 EDT 1991
+
+ source.c Extended source_info() to include the source language in
+ the output from "info source".
+
+Fri Jul 5 13:48:52 EDT 1991
+
+ utils.c Moved the support functions for the GDB set/show commands
+ dealing with language into language.c.
+ language.c Added the function language_info(), which displays info
+ about the current working language, type and range check
+ settings. Called via the GDB command "info language".
+ Added an initialization routine _initialize_language(),
+ that sets defaults for the language, type and range
+ variables and sets up the new GDB commands.
+ main.c Language setup moved to language.c.
+ depend Rebuilt.
+
+Mon Jul 8 10:10:22 EDT 1991
+
+ valarith.c Debugged the range checker for arithmetic. Still does not
+ work for multiplication very well.
+
+Mon Jul 8 12:40:37 EDT 1991
+
+ language.[ch] Added the function value_true() which returns non-zero if
+ its argument represents a boolean true value.
+ breakpoint.c Changed breakpoint_cond_eval() to call value_true() to
+ check the truth of an expression.
+
+Thu Jul 11 12:51:34 EDT 1991
+
+ language.[ch] Added the predicate structured_type(), which returns
+ non-zero if the argument is a structured type.
+ Added the predicate pointer_type(), which returns non-zero
+ if the argument is a pointer type.
+ eval.c Added the ability to do addition and substraction on
+ pointers and integers. This case simply bypasses the
+ type checker.
+
+Thu Jul 11 14:41:42 EDT 1991
+
+ include/stab.def
+ Added the symbol N_DEFD (0x4a) which is a definition
+ module dependency that is used by the GNU Modula-2
+ compiler and the linker. It is not important to GDB,
+ except that [dbx|coff|mips]read.c should ignore these
+ symbols.
+
+Fri Jul 12 16:07:00 EDT 1991
+
+ valprint.c Changed the TYPE_LENGTH(type) >= 0 to TYPE_LENGTH(type) >
+ 0 in val_print(). Also added statements to the else part
+ to coerce type (argument to val_print) to a pointer type
+ if it is an "array of unspecified length".
+ valops.c Added the function value_m2_string(), which returns a
+ (value) value which is a constant string, whose type is
+ (ARRAY [0..n] OF CHAR). The length field of the type
+ structure is set to zero, so it will be interpreted as an
+ "array of unspecified length".
+ stack.c Moved the language/frame mismatch check to
+ main.c:execute_command().
+ main.c The working language is recorded each time
+ execute_command() is executed. If working lang has
+ changed during its execution, then the new
+ language/type/range info is printed out for the user. If
+ the working language does not match the language of the
+ frame, a warning is issued.
+
+Sat Jul 13 16:16:39 EDT 1991
+
+ eval.c Moved all the type-checking stuff for operators to
+ language.[ch] language.c. This is so we can keep language-specific
+ stuff (like for what type operators are defined) in
+ language.c.
+ language.[ch] Added the function binop_type_check(), which checks to see
+ if its two (value) arguments are type-compatible with its
+ opcode argument. The opcode should represent an operation
+ involving an operator. Also added the macro function
+ unop_type_check, which calls binop_type_check with a
+ NULL second argument.
+ expprint.c Added Modula-2 operators to the op_print_tab, so info
+ expression.h break works correctly. Also added "op_string", which
+ returns the string corresponding to the (enum exp_opcode)
+ opcode that is its argument.
+
+
+Sat Jul 13 18:26:18 EDT 1991
+
+ coffread.c Added code to record the type of function arguments with
+ each paricular function. Code is very similar to that
+ added to dbxread.c.
+ dbxread.c Moved add_param_to_type() to symtab.c
+ symtab.[ch] Added function add_param_to_type() from dbxread.c
+
+ *** NOTE: The above additions have not been tested.
+
+Mon Jul 15 12:50:47 EDT 1991
+
+ langauge.[ch] Added the functions type_error and range_error, which work
+ like error() except if the type/range mode is set to
+ *_mode_warn, then they do not do a return_to_top_level(),
+ but merely print a warning.
+ Also changed [set|show]_[type|range]_command() to support
+ the new "warn" feature.
+
+Thu Jul 18 17:50:54 EDT 1991
+
+ mipsread.c Added code to record the type of function arguments with
+ each particular function. Code is very similar to that
+ added to dbxread.c.
+
+ *** NOTE: The above additions have not been tested.
+
+Fri Jul 19 11:19:10 EDT 1991
+
+ defs.h Added macros MAX_OF_SIZE, MIN_OF_SIZE, UMAX_OF_SIZE, and
+ UMIN_OF_SIZE, which when given a size of a numeric type,
+ return the maximum and minimum value it can hold. UMAX...
+ and UMIN... return the result for unsigned types.
+ symtab.h Added the macros MAX_OF_TYPE and MIN_OF_TYPE to operate on
+ struct types. They call above macros.
+ dbxread.c Renamed the MAX and MIN_OF_TYPE macros to ..._OF_CTYPE to
+ avoid a name conlict with the above.
+ c-exp.y Added range checking on numeric constants in
+ parse_number() for completeness.
+ valarith.c Made binop_user_defined_p() and unop_user_defined_p()
+ return 0 if working_lang is not language_c.
+
+Thu Aug 8 14:17:22 EDT 1991
+
+ main.c
+ printcmd.c
+ breakpoint.c Documentation strings of some commands changed to
+ eliminate the references to the C language where
+ appropriate.
+
+Tue Aug 13 15:48:03 EDT 1991
+
+ m2-exp.y Added qualified identifiers to the grammar. The semantics
+ are slightly different from those of the GDB operator ::
+ c-exp.y
+ m2-exp.y Added a rule to each grammar of the form: start ::= exp |
+ type_exp, where type_exp is any valid type expression.
+ expression.h
+ eval.c Added the opcode OP_TYPE, and an error case in eval.c.
+ printcmd.c Modified ptype_command() so it actually parses the input
+ (necessary for type expressions with scope qualifiers).
+ Added the function ptype_eval() which expects an
+ expression composed of one OP_TYPE element.
+ *.[ch] Replaced all occurences of parse_c_expression with
+ parse_expression
+ *.[ch] Replaced all occurences of parse_c_1 with parse_exp_1

+[End of ChangeLog entries from Andrew Beers for Modula-2 support.]
+
+Mon Sep 16 17:19:46 1991 John Gilmore (gnu at cygnus.com)
+
+ Small fixes from Peter Schauer:
+
+ * infrun.c (child_attach): Lint.
+ * solib.c (find_solib): Handle shared libs version 2.
+
+ Small fixes from David Wood:
+
+ * xm-ultra3.h (SYS_SIGLIST_MISSING): Typo.
+
+ Small fixes:
+
+ * remote-vx.c: Move <stdio.h> to top, for FILE. Fix from
+ John S <basrai%kanga.dnet@c3po.sm-alc.af.mil>.
+
+ * utils.c (wrap_here): Avoid wrap action of fputs_filtered if
+ chars_per_line is at maximum (user typed `set width 0'). Fix
+ from Andreas Schwab <schwab@ls5.informatik.uni-dortmund.de>.
+
+Tue Sep 17 17:31:04 1991 Stu Grossman (grossman at cygnus.com)
+
+ * coredep.c: include ptrace.h where necessary.
+ * mipsread.c(parse_lines): fix unsigned char problem that was
+ messing up line numbers on SGI's and possibly other MIPS based
+ platforms.
+ * infrun.c (child_create_inferior): use better test to check
+ return val from setpgrp().
+ * tm-irix3.h, xm-irix3.h, tconfig/irix3, xconfig/irix3: add these
+ for sgi/irix support.
+
+Wed Sep 18 04:33:31 1991 Per Bothner (bothner at cygnus.com)
+
+ * mipsread.c (parse_symbol): Put non-static procedures
+ in the global block.
+
+Fri Sep 13 00:14:52 1991 John Gilmore (gnu at cygnus.com)
+
+ Patch together `text_start' and `text_end' for 29K port.
+
+ * exec.c (exec_command): If NEED_TEXT_START_END, define the
+ variables and set them based on the exec file.
+ * am29k-tdep.c: declare text_start.
+ * valops.c (call_function_by_hand): declare text_end.
+
+ * inferior.h: Eliminate CANNOT_EXECUTE_STACK in favor of
+ defining CALL_DUMMY_LOCATION as BEFORE_TEXT_END. This is
+ because machines that do this will also have to know to
+ set NEED_TEXT_START_END. Besides, it was a redundant way to
+ say the same thing.
+ * tm-29k.h, tm-convex.h, tm-np1.h: Eliminate
+ CANNOT_EXECUTE_STACK, define CALL_DUMMY_LOCATION and
+ NEED_TEXT_START_END.
+
+Thu Sep 12 00:22:24 1991 John Gilmore (gnu at cygint.cygnus.com)
+
+ AMD 29000 changes from David Wood <wood@david.ultra.nyu.edu>:
+
+ * Makefile.in (CLIBS): Put XM_CLIBS and TM_CLIBS at end.
+ Pass MUNCH_DEFINE to munch whenever we run it.
+ * am29k-pinsn.c (print_insn): Handle NOP specially. Avoid %#x
+ format string; use 0x%x instead.
+ * am29k-tdep.c: Use DUMMY_SAVE_GREGS and RETURN_REGNUM.
+ * ultra-xdep.c, xm-ultra.h: New files for Ultracomputer host system.
+ * xm-rtbsd.h: New host support for RT/PC running BSD Unix.
+ * inflow.c: Handle `short' process group IDs.
+ * infptrace.c (fetch_register): Support CANNOT_FETCH_REGISTER,
+ and check for ptrace errors.
+ * coffread.c (SDB_REG_TO_REGNUM): Define if not already.
+ (coff_symfile_init): Initialize text_bfd_scnum.
+ (read_coff_symtab): Use it to find the text [and absolute?] sections.
+ * ../config.sub: Add vendor nyu and os "sym[1-9]*".
+ * configure.in: Add hosts rtpc-*-* and a29k-*-*.
+ Merge target arm case with other "easy" cases. Add target
+ cases a29k-*-none (rehack of am29k), a29k-*-kern (remote to
+ Ultracomputer kernel), and a29k-*-sym1 (ultracomputer OS's user
+ process).
+ * minimon.h, remote-adapt.c, remote-mm.c: Add.
+ * munch: Cope with RT/PC putting fns in data segment.
+ Restore ability to override `nm' by specifying MUNCH_NM.
+ * xconfig/rtbsd, xconfig/ultra3: New host systems.
+ * tconfig/a29k: Rename from tconfig/am29k. Add remote-mm
+ and remote-adapt. Remove encapsulated coff #define's (the
+ support should go in BFD, and gdb shouldn't know or care).
+ * tconfig/a29k-kern: Same, but for remote kernel debugging.
+ * tconfig/ultra3: For debugging user processes on Ultra3/Sym1.
+ * tm-29k.h: Update BADMAG (though it should go away).
+ Allow the register definitions to be overridden in another
+ tm-file. Fix SR_REGNUM. Add a mess of _REGNUM's. Separate
+ RETURN_REGNUM from GR96_REGNUM and DUMMY_SAVE_GREGS from
+ DUMMY_SAVE_GR96, for handling kernel calling conventions
+ that use GR64+ rather than GR96+.
+ * tm-ultra3.h: New file, for use on Ultra3 Unix as well as for
+ remote debugging of Ultra3 kernel. Includes tm-29k.h and
+ overrides various things.
+
+ * remote-mm.c (mm_attach, mm_wait): Handle attach like
+ child_attach does, making a clean stop in the newly attached
+ program.
+ * remote-eb.c: Lint.
+
+ * coffread.c: Make coffread independent of any particular
+ variant of COFF. Avoid #include-ing any particular one except
+ internalcoff.h. BFD now passes key values for symbol reading
+ as part of its coff_data structure (LINESZ, SYMESZ, AUXESZ,
+ and the symbol masks and shifts); use them.
+ Remove obsolete end_of_text_addr.
+
+ * exec.c: Remove unused include files.
+
+Wed Sep 11 19:38:44 1991 John Gilmore (gnu at cygint.cygnus.com)

+
+ * core.c (core_file_command): Print frame at coredump with
+ its level number, by calling print_stack_frame.
+ * frame.h: Add selected_frame_level, print_stack_frame.
+ * frame.h, stack.c: Remove print_sel_frame, print_selected_frame.
+ * convex-tdep.c, convex-xdep.c, infcmd.c, inflow.c, infrun.c:
+ Change print_sel_frame and print_selected_frame callers to
+ print_stack_frame.
+
+ * dbxread.c (read_ofile_symtab): Avoid empty else clause.
+ * symfile.c (free_named_symtabs): Ditto.

+ * solib.c (find_solib): Avoid memory access if _DYNAMIC is zero.
+ (solib_add): Avoid noise.
+ (solib_create_inferior_hook): Lint.
+ (sharedlibrary_command): Move dont_repeat to here.
+ * utils.c (error): Call wrap_here to force buffered output.
+
+ Small patches from Peter Schauer:
+
+ * coffread.c (start_symtab): Free any existing line_vector before
+ malloc-ing new one.
+ (read_coff_symtab): Ditto for type_vector.
+
+ * source.c (lines_to_list): New variable, replacing function.
+ (all uses): Use as variable.

+Mon Sep 9 13:45:57 1991 John Gilmore (gnu at cygint.cygnus.com)
+
+ * breakpoint.c (insert_breakpoints): Restore warning about
+ the program might be running in another process, but only for
+ systems with this brain death (#ifdef ONE_PROCESS_WRITETEXT).
+ * xm-hp300bsd.h, xm-mips.h, xm-vax.h: Define it.
+
+ * utils.c (error): if error_pre_print is set, print the string
+ first.
+ * main.c (main, print_gnu_advertisement, print_gdb_version):
+ Reformat legalese so it always prints, but acts as an "I'm here"
+ message while symbols are being read. If any errors occur,
+ print a few newlines to set off the message and start it at the
+ left margin. Remove mention of "help" command, and don't yak
+ about symbol reading.
+ (catch_errors): Error string is now printed first in case of
+ error, not last.
+ * command.c (undef_cmd_error, lookup_cmd): On undefined command,
+ suggest the "help" command.
+
+ * Makefile.in (VERSION): Set to 4.0.2.
+
+Thu Sep 5 23:49:48 1991 John Gilmore (gnu at cygint.cygnus.com)
+
+ * .gdbinit: Remove useless "rr" command. Set complaints
+ to 1 for people debugging gdb.
+
+ * breakpoint.c, remote-vx.c: Reword strings printed by
+ catch_errors callers.
+
+Wed Sep 4 11:07:50 1991 John Gilmore (gnu at cygint.cygnus.com)
+
+ * WHATS.NEW: "history write -> history save". Doc "write on/off".
+ (Fix from kenc@viewlogic.com.)
+
+ Fix some infrastructure to be able to cope with host and target
+ machines with different sized basic types (ints, ptrs, etc).
+ (Idea from pierre@la.tce.com (Pierre Willard).)
+
+ * values.c (value_from_longest): Rename from value_from_long.
+ Handle pointer types as well as integers, so that targets with
+ different pointer sizes from the host can be accomodated.
+ * breakpoint.c, convex-tdep.c, eval.c, expprint.c, printcmd.c,
+ valarith.c, valops.c, valprint.c, value.h, values.c: Rename
+ uses of value_from_long to value_from_longest.
+ * eval.c, findvar.c, printcmd.c, valarith.c, valops.c: Pass
+ the correct pointer type to value_from_long{est}.
+
+ * doc/gdb.texinfo ($_, $__): Describe types of these variables.
+
+ * remote-vx.c: Remove obsolete code for calling functions via
+ vxworks kludge interface (it referenced value_from_long).
+
+ * valops.c (value_string): Find malloc with lookup_misc_func, not
+ raw search.
+
+Tue Sep 3 18:37:46 1991 John Gilmore (gnu at cygint.cygnus.com)
+
+ Make writing to files work properly. (Fixes to BFD are also needed.)
+
+ * core.c (core_open): Open file ourselves, read or r/w, depending on
+ write_files. Use bfd_fdopenr.
+ * gdbcore.h (write_files): New variable.
+ * exec.c (write_files): Define variable, add set&show for it.
+ (exec_file_command): Use write_files to open for read or r/write.
+
+ Make shared library reading happen automatically. These changes
+ are mostly from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>.
+
+ * inferior.h (stop_soon_quietly): Add to exported variables.
+ * infrun.c (child_create_inferior): call solib hook, if defined.
+ (child_attach): call solib hook, if defined.
+ * solib.c: Include inferior.h. Add from_tty to so_list as kludge.
+ (find_solib): Use lookup_misc_func rather than hand-rolled.
+ (symbol_add_stub): New stub for catch_errors.
+ (solib_add): Avoid output if !from_tty. Catch errors rather
+ than just calling symbol_file_add and bombing.
+ (solib_create_inferior_hook): Interface with the target process
+ to let it read and alloc shared libs, then figure out what it did.
+
+ * core.c (validate_files): Fix typo, soften warning.
+ (Fix from Hiroto Kagotani <kagotani@cs.titech.ac.jp>.)
+
+ * utils.c (fputs_demangled): Avoid duplicate printing if
+ demangling is off. (Fix from J.T. Conklin <jtc@cayenne.com>.)
+
+ * infrun.c (proceed): Cast -1 to (CORE_ADDR) before comparing.
+ (Fix from pierre@la.tce.com (Pierre Willard).)
+
+ * main.c (catch_errors): Change argument to a char * from an int,
+ since a char * can point to a struct full of glop, but an int
+ is not guaranteed to be able to hold a pointer.
+ * breakpoint.c (breakpoint_cond_eval, bpstat_stop_status,
+ breakpoint_re_set_one, breakpoint_re_set): Adapt.
+ * core.c (core_open, solib_add_stub): Adapt.

+
+Wed Aug 28 18:18:05 1991 John Gilmore (gnu at cygint.cygnus.com)

+
+Thu Aug 22 22:17:06 1991 Stu Grossman (grossman at cygint.cygnus.com)
+
+ * coffread.c, symfile.c, stack.c: saberized.

+ cplus-dem.c, values.c, valprint.c, symfile.c, remote.c,
+ breakpoint.c, main.c: lint.
+
+Thu Aug 22 02:02:26 1991 John Gilmore (gnu at cygint.cygnus.com)
+
+ Install new configuration scheme for GDB and friends.
+
+ * config.sub: Translate ordinary names to three-part names.
+ * configure: Use three-part names internally.
+ * configure.in: Translate three-part names to filenames.
+
+ * README, WHATS.NEW: Update for gdb-4.0.
+ * Makefile.in: Roll VERSION to 3.99.
+
+Wed Aug 21 18:21:09 1991 John Gilmore (gnu at cygint.cygnus.com)
+
+ * infptrace.c (KERNEL_U_ADDR_BSD): Include a.out.gnu.h.
+ * i960-tdep.c, m68k-tdep.c, sparc-tdep.c, tm-i960.h,
+ tm-m68k.h, remote-nindy.c: Change ext_format_XXX structs
+ to single structures rather than arrays; when passing
+ their address, use &. This avoids trouble with bdead compilers.
+ * mcheck.c: Don't include <stdlib.h>; just declare "void abort();"
+ instead. This avoids portability headaches.
+ * mips-tdep.c (mips_do_registers_info): Only print FP regs if
+ asked to.
+ * source.c (open_source_file): Avoid ANSI const bdeath by
+ skipping declaration and then casting result value.
+ * tm-hp300bsd.h: Clarify comment.
+ * utils.c (strstr): Result is const char *; ANSI bdeath.
+ * xm-hp300bsd.h: Define HOST_BYTE_ORDER. Redefine INT_MIN,
+ since system include file defines it differently from "defs.h",
+ though the two are equivalent for our purposes.
+ * tconfig/hp300bsd: Add m68k-tdep.o.
+
+Tue Aug 20 16:01:11 1991 John Gilmore (gnu at cygint.cygnus.com)
+
+ * tconfig/sun*4: Remove warnings about system assembler.
+
+Mon Aug 19 13:44:46 1991 John Gilmore (gnu at cygint.cygnus.com)
+
+ * mcheck.c: Avoid warning about undeclared abort fn.
+ * tm-sparc.h (PC_ADJUST): Avoid calling error() from this;
+ it causes recursive calls to error() when used in cleanups.
+ To do so requires that we make it a function, so we do.
+ * sparc-tdep.c (sparc_pc_adjust): New implem of PC_ADJUST.
+ * utils.c (do_cleanups): Remove the current cleanup from the
+ chain *before* calling it, in case error() is called from it.
+ The result won't be pretty, but won't be an infinite loop either.
+
+Mon Aug 19 00:41:04 1991 Michael Tiemann (tiemann at cygint.cygnus.com)
+
+ * dbxread.c (read_struct_type): Grok anon structs for C++.
+ (vb_name, vptr_name): Null terminate these strings.
+
+Fri Aug 16 08:31:03 1991 John Gilmore (gnu at cygint.cygnus.com)
+
+ Minor bug fixes from BSD Net2 gdb:
+
+ * blockframe.c (get_prev_frame_info): If FRAME_CHAIN_COMBINE
+ returns 0, there is no previous frame.
+ * breakpoint.c (commands_command): If !from_tty, don't call
+ input_from_terminal_p().
+ * dbxread.c (record_misc_function): Speed up slightly.
+ (compare_psymbols): Ditto.
+ * infcmd.c (do_registers_info): Take a second argument to
+ determine whether to print float registers. "info registers"
+ does not do so anymore. "info all-registers" does, now.
+ * mips-tdep.c, pyr-tdep.c (xxx_do_registers_info): Take second
+ arg and ignore it.
+ * tm-mips.h, tm-pyr.h (DO_REGISTERS_INFO): Pass second arg.
+ * inflow.c (initialize_inflow): Set tflags_ours correctly.
+
+ Other fixes:
+
+ * breakpoint.c (bpstat_do_actions): Use a cleanup to restore
+ executing_breakpoint_commands if we are interrupted by error.
+ * coffread.c (init_lineno): Avoid problem with zero-sized linetab
+ versus malloc/free. From: john@labtam.labtam.oz.au (John Carey).
+ * core.c (solib_add_stub, core_open): Call SOLIB_ADD inside a
+ catch_errors() so we can setup the frame regardless of whether
+ the shared libs work.
+ * ieee-float.c (double_to_ieee_extended): Get exponent from
+ right place in little-endian systems. From John Carey.
+
+Thu Aug 15 18:43:57 1991 John Gilmore (gnu at cygint.cygnus.com)
+
+ * main.c: Remove unused terminating_signals and catch_termination().
+ (long_options): Terminate with a zero element.
+ [Bugfix from Atsuo Kawaguchi <atsuo@hark86.harl.hitachi.co.jp>.]
+ (gdb_readline): Make call-compatible with readline.
+ (init_signals): Improve comments re vfork vs. signal.
+
+ * utils.c (prompt_for_continue): Use new gdb_readline().
+ If we prompt for continuation, we don't let CR repeat the previous
+ command, once we get back to a prompt. It's too easy to keep
+ hitting CR, expecting "--more--" prompts, and have some long
+ command start repeating on you.
+
+Tue Aug 13 16:17:56 1991 John Gilmore (gnu at cygint.cygnus.com)
+
+ * blockframe.c (frameless_look_for_prologue): Speed up by
+ calling SKIP_PROLOGUE_FRAMELESS_P if it's defined.
+ * tm-sparc.h (SKIP_PROLOGUE, SKIP_PROLOGUE_FRAMELESS_P):
+ Define two variants, one faster.
+ * sparc-tdep.c (sparc_frame_chain): Use target_read_memory
+ and return zero, rather than giving an error.
+ (setup_arbitrary_frame): Initialize the PC in the new frame.
+ (skip_prologue): Add a second arg saying whether we're just
+ checking for a frameless function or not.
+
+ * core.c (core_open, core_close, core_xfer_memory): Move
+ section table pointers and bfd* into the target_ops.
+ (core_open): Allow errors in shared lib reading, etc.
+ (core_files_info): Describe shared library sections.
+
+ * exec.c (exec_open, exec_close, exec_xfer_memory, xfer_memory,
+ exec_files_info, set_section_command): Move section table
+ pointers and bfd* into the target_ops.
+ (add_to_section_table): Add BFD to section table.
+
+ * target.c (target_xfer_memory, target_info): Pass target to
+ xfer_memory and target_info functions.
+ * target.h: ''
+
+ * gdbcore.h: Move struct section_table.
+ * target.h: New home of struct section_table.
+
+ * solib.c (solib_add): New argument is the target_ops whose
+ section list is to be added to, if any. Reallocate the
+ sections in that target to add any that come from shared libs.
+ (throughout) so_sections renamed to sections.
+ (solib_xfer_memory): Deleted.
+ * tm-sunos.h (SOLIB_ADD): Add target argument.
+ (SOLIB_XFER_MEMORY): Delete.
+
+ * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
+ remote-vx.c, remote.c, target.c, target.h: Remove add_syms vector
+ from target_ops. It's the same on all targets. Add two section
+ pointers to target_ops.
+
+ * stack.c (find_relative_frame): Dump ancient algorithm for
+ "down", just use handy "next" pointers.
+ (frame_command): Don't error if there is no stack; let user
+ set one.
+
+ * inflow.c (new_tty_prefork, new_tty): New prefork routine
+ modifies static state in the parent process; new_tty itself
+ runs in the child and modifies the child's file descriptors
+ to match the saved static state.
+ * infrun.c (child_create_inferior): Call new_tty_prefork,
+ fork, then new_tty.
+
+ * infptrace.c (child_xfer_memory): Add ignored target arg.
+ * remote-eb.c (eb_xfer_inferior_memory): ''
+ * remote-nindy.c (nindy_xfer_inferior_memory): ''
+ * remote-vx.c (vx_xfer_memory): ''
+ * remote.c (remote_xfer_memory): ''. Rename from
+ remote_xfer_inferior_memory.
+
+ * main.c (main): Only try to attach "corefile" argument if
+ it starts with a digit.
+
+ * symfile.c (symbol_reloading): New "set/show" variable.
+ (symbol_file_add): Shorten message about symbol reading.
+ (add_symbol_file_command): Merge with add_syms_addr_command,
+ since this should work on all targets now.
+ (stop_whining): Default to zero, to shut up complaints
+ about bad symbol tables on many systems.
+ (free_named_symtabs): Just exit unless symbol_reloading.
+
+ * xm-sun3os4.h, xm-sun4os4.h: Define BROKEN_LARGE_ALLOCA,
+ and add comment explaining shared library screw.
+
+ * source.c: #if defined => #ifdef.
+
+Thu Aug 8 12:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
+
+ * doc/gdbint.texinfo: Improve doc on porting to new OS's.
+
+Tue Aug 6 17:16:15 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
+
+ * doc/rdl-apps.texinfo: provide default readline-appendix finder
+ (doc/Makefile knows how to make one for local config)
+
+ * Makefile.in: use doc/Makefile for doc targets
+
+ * doc/Makefile: GDB documentation now has its own Makefile
+ doc/refcard.tex: renamed from "gdbrc.tex"
+ doc/gdbint.texinfo: add markup in "Cleanups" chapter
+
+
+Fri Aug 2 00:13:06 1991 John Gilmore (gnu at cygint.cygnus.com)
+
+ * values.c (baseclass_addr): When reading target memory, use the
+ length of the basetype, not the upper type. We've only malloc'd
+ enough space for the basetype, leading to errors in free().
+
+ * expprint.c (print_subexp): Print UNOP_MEMVAL of an OP_LONG that
+ ends up as a function specially, since we know the actual type of
+ the pointed-to address. This (somewhat) fixes display of
+ expressions that include misc_function_vector names. Try `cond 1
+ !strcmp("a","b")' then `i b'.
+
+ * infrun.c: Move DO_DEFERRED_STORES from proceed() to resume().
+ The child can be proceeded from inside wait_for_inferior in
+ evaluating breakpoint conditions, and DO_DEFERRED_STORES was
+ getting skipped in that case.
+
+ * expprint.c (print_subexp): Use filtered output, since the
+ subroutines we call use it, otherwise the output is horribly
+ mangled, since output of wrappable stuff comes out late.
+
+ * Makefile.in: Bump VERSION to 3.98.1
+
+ * infrun.c (child_create_process): Use execlp to find the
+ shell to exec our target program. This requires some fiddling
+ with `environ' since there is no execlpe().
+
+Thu Aug 1 15:35:17 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
+
+ * Makefile.in, doc/gdbrc.tex, doc/rc-* (new files):
+ Minor rearrangement of refcard permits two new make targets--
+ gdbrc.dvi DVI output for refcard, using CM fonts
+ gdbrc.ps PostScript refcard, using PS fonts
+
+Wed Jul 31 16:46:21 1991 John Gilmore (gnu at cygint.cygnus.com)
+
+ * GDB-3.98 release.
+
+ * TODO, Projects, WHATS.NEW, README: Update for gdb-3.98.
+ * Makefile.in (gdb-all.texinfo): Avoid touching file if M4 dies.
+
+Wed Jul 31 16:35:58 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
+
+ * doc/gdb.texinfo: last changes for release.
+ Minor typo and formatting fixes; incorporated most fixes remaining from
+ filed mail commenting on earlier drafts.
+
+ Added warnings: pipes don't work in run command;
+ conditions are converse of assertions;
+ step over fn without debug info goes to next fn;
+ vars may have "wrong" values near fn entrance, exit
+
+ Added example from Kingston on printing repeated nonadjacent values
+
+ Added explicit mention that in Emacs gdb mode C-c and C-z are like
+ shell mode for signals
+
+ Renamed "Stepping and Continuing" to "Continuing and Stepping" so it
+ doesn't sound so much like its parent "Stopping and Continuing"; also
+ moved entries on continue to top of section, so they don't get lost.
+
+ Improved installation directions in appendix, added manual formatting
+ instructions
+
+Tue Jul 30 17:26:39 1991 John Gilmore (gnu at cygint.cygnus.com)
+
+ * configure.in: Remove xm.h and tm.h even if we aren't linking
+ new ones, so "./configure sun4; ./configure none" does the right
+ thing. Assume that alldeps.mak and depend are already built in
+ srcdir, and avoid running "make" (particularly "make depend",
+ which involves "gcc") from inside configure. Build Makefile
+ directly rather than building Makefile.conf first.
+ * configure: Regenerate with above changes.
+ * Makefile.in: Use $(BISON) to find bison. Roll VERSION
+ to 3.98. Revise gdb.tar.Z procedure to produce a file
+ called gdb-$(VERSION).tar.Z but which unpacks into a
+ directory called "gdb". Move non-source files out of
+ $(SFILES_SUBDIR). Pretty up alldeps.mak with comments.
+ (depend): Don't try to do "gcc expread.y".
+ (expread.o): Update dependencies by hand.
+
+Mon Jul 29 15:21:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
+
+ * doc/gdb.texinfo:
+ Fixed a variety of small typos that prevented info from formatting
+ cleanly; altered too-long heading for GPL Appendix, as discussed
+ w/RMS; Changed date on cover to July 91.
+
+Fri Jul 26 13:20:02 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
+
+ * doc/gdb.texinfo:
+ (1) Applied some fixes due to comments from Larry Breed (easier ones
+ through chapsec 5.2)
+ (2) Eliminated use of @footnote---had my doubts about it anyways, and
+ it's broken in latest texinfo
+ (3) Introduced *some* use of [] for optional arguments, where
+ explanation is not simpler by listing cmd w arg and cmd w/out arg
+ separately. Still not using @deffn.
+ (4) Dropped in GPL-2. NOTE: one of GPL-2 or texinfo is broken; a
+ couple of headings are too long. Need patches to texinfo or revision
+ to GPL-2.
+
+ * Partial update to README (which still needs work for this
+ release!): (1) use of configure corrected for new script,
+ (2) "make gdb.dvi" and "make gdb.info" mentioned.
+
+Wed Jul 24 06:44:02 1991 John Gilmore (gnu at cygint.cygnus.com)
+
+ * symtab.c (lookup_symbol): Don't complain right off about
+ no debug symbols; use the misc function vector first.
+ (list_symbols): Use misc function vector to find symbols
+ that don't have debug info, and print them.
+ (find_pc_symtab): Temporarily avoid fatal() when psymtab
+ PC range doesn't match symtab PC range, as it does on the
+ MIPS because our symtab reading isn't perfect.
+
+ * dbxread.c (dbx_symfile_read): Make warning about
+ "no debug symbols" slightly nicer.
+
+ * source.c (select_source_symtab): If "main" symbol exists,
+ but decode_line_spec can't find line info, don't just return
+ a zero; try other source symtabs or give an error.
+
+ * mipsread.c (parse_partial_symbols): Sort the psymtabs by
+ their low addresses first, then rip through fixing high addrs.
+
+ * ns32k-opcode.h (sfsr): Bugfix from Rune Nerg}rd,
+ <runene@ifi.uio.no>.
+ (NS32K_SVC_IMMED_OPERANDS): Reverse the #ifndef.
+
+Tue Jul 23 18:52:43 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
+
+ * Minor, mostly mechanical, cleanup of doc subdir for clean
+ makeinfo'ing and TeXing; also ensured gdb-all.texinfo (post-m4)
+ and gdb.info (post- texinfo2 makeinfo) generated for distribution.
+
+Sun Jul 21 03:54:52 1991 John Gilmore (gnu at cygint.cygnus.com)
+
+ Mostly MIPS and general symbol-reading fixups.
+
+ * doc/gdbint.texinfo: Add documentation on symbol-reading
+ interface.
+
+ * mipsread.c: Remove kludges around #include "ecoff.h".
+ Remove redefinitions of a_magic, etc, no longer used.
+ (parse_symbol, ): Convert "Internal:" printfs to complain()ts.
+ Fix global overview comments to match symfile.c protocol.
+ (mipscoff_new_init): Eliminate cur_hdr if we have one.
+ (mipscoff_symfile_read): Eliminate unused code. Avoid
+ sorting all the symtabs, when all we have read here is psymtabs.
+ The symtabs are sorted as they are created anyway. Tell
+ condense_misc_bunches whether we're mainline.
+ (psymtab_to_symtab_1): Pass filename when recursing, to make
+ stack trace more informative.
+ (parse_partial_symbols): Assume cur_hdr as argument.
+ (read_mips_symtab): Don't clobber cur_hdr, so it can be freed.
+ Pass cur_hdr implicitly to parse_partial_symbols. Avoid checking
+ the TYPE_NAME of char *, since that's done in symfile.c.
+ (free_numargs, parse_symbol, add_symbol, add_block,
+ shrink_linetable): Declare these fns void.
+ (upgrade_type): Convert tree of if's to switch. Clean up
+ bogus "off == 0" handling with a complaint. Avoid setting
+ field bitpos and bitsize of array with lower and upper bounds.
+ Check specified bitsize of elements against their actual type's
+ bitsize, and complain if different. Complain about unknown
+ type qualifiers.
+ (parse_fdr): Don't assume sizeof(char *) == sizeof (struct *).
+ (psymtab_to_symtab_1): Print names of subsidiary files that
+ are being read in. FIXME, we read far too many files. This code
+ is not the problem, the problem is in parse_fdr where the psymtabs
+ are set up.
+ (cross_ref): Result should indicate that we used one aux entry
+ normally, or two if we encountered a "next" entry. This used
+ to leave the caller pointing at the wrong aux entry.
+ (add_symbol): If overflowed cur_block, reallocate it larger,
+ chase all pointers to it, and complain(), rather than clobber memory.
+ (shrink_block): Use xrealloc rather than xmalloc-and-copy.
+ (new_field): Only allocate one field initially, not two.
+ Pull ++ out of macro argument. Simplify.
+ (_initialize_mipsread): Avoid initialization of importd
+ global_psymbols and static_psymbols.
+
+ * symfile.c (psymtab_to_symtab): Depend on XXX_psymtab_to_symtab
+ to properly set pst->symtab; avoid searching for it.
+ (symfile_fns): Improve comments, add a FIXME.
+ * dbxread.c: Update comments to reflect symfile protocol.
+ (read_ofile_symtab, end_symtab): Return the symtab.
+ (psymtab_to_symtab_1): Set pst->symtab.
+
+ * coffread.c (coff_symfile_read): tell condense_misc_bunches
+ whether we're mainline.
+
+ * symfile.h (sym_fns): Remove unused sym_discard member.
+ * coffread.c, mipsread.c, dbxread.c: Remove XXX_symfile_discard.
+
+ * mtrace.c (mtrace): Take effect if mallwatch is set, even if
+ the environment variable is not.
+ * infcmd.c (finish_command): Use filtered printfs.
+ * cplus-dem.c: Add struct tags to a few unnamed structs.
+ * valops.c (value_coerce_array): Improve comments.
+ * valprint.c (type_print_varspec_suffix): Print array size only
+ if greater than zero.
+ * m88k-tdep.c: Shift some lines left by one space, that had
+ apparently been trashed at some point.
+ * TODO: More things to do, a few got done.
+
+Thu Jul 18 22:46:05 1991 John Gilmore (gnu at cygint.cygnus.com)
+
+ * symtab.h (LOC_EXTERNAL): Eliminate in favor of LOC_STATIC.
+ (ldsymoff, ldsymlen, globals_offset, statics_offset): Improve
+ comments.
+ * dbxread.c (read_dbx_symtab): LOC_EXTERNAL -> LOC_STATIC.
+ * expread.y, findvar.c, symmisc.c: Ditto.
+ * printcmd.c (address_info): Update printed forms of LOC_
+ symbols. Elim LOC_EXTERNAL.
+ (print_frame_args): Keep track of param stack offsets before
+ re-looking up to find the local register param is kept in.
+
+ * mipsread.c: Use <symconst.h> and <sym.h> rather than <syms.h>.
+ Further integration of mipsread into gdb. Eliminate unused
+ routines, duplicate declarations. Handle static symbols in
+ psymtabs as well as external symbols. When reading symtabs,
+ insert symbols into the correct block (global, static, or a local
+ block).
+ (read_mips_symtab, parse_partial_symbols): Don't pass useless
+ "incremental" arg.
+ (mipscoff_symfile_read): Don't call select_source_symtab.
+ (parse_symbol): Use SYMBOL_VALUE_ADDRESS where appropriate,
+ rather than SYMBOL_VALUE.
+ (parse_external): Comment clobbering of top_stack.
+ (parse_partial_symbols): Update comments. Allocate and parse
+ static symbols as well as external symbols. FIXME, enum values
+ are not handled in this pass, but should be. Inline new_psymbol.
+ Use SYMBOL_VALUE_ADDRESS.
+ (psymtab_to_symtab_1): Read symbols into global static block
+ by default (until enter some function's local block context).
+ (sort_blocks): Clean up STATIC_BLOCK as well as GLOBAL_BLOCK.
+ (destroy_all_symtabs, new_psymbol): Eliminate, unused.
+
+ * source.c (select_source_symtab): Select a source symtab
+ from either the symtabs or, failing that, the psymtabs.
+ (list_command): Update error message.
+ (forward_search_command, reverse_search_command): Use getc, not
+ fgetc, for speed. FIXME, add comment about buffers that die if
+ overrun by long line.
+
+ * values.c (unpack_field_as_long, modify_field): Avoid shifting
+ by an entire word, which is not portable, if we have a 32-bit
+ field. (Code in dbxread.c already turns such bitfields, if
+ aligned, into ordinary ints, but fixing this will help for other
+ symbol formats and for future changes.)
+ * core.c (core_open): Handle ANSI const brain death.
+ * utils.c (vprintf): Fix varargs typo.
+
+Sun Jul 14 00:42:53 1991 John Gilmore (gnu at cygint.cygnus.com)
+
+ * findvar.c (find_var_value): Handle &function better.
+ * TODO: Document work needed on &fn and &array.
+ * printcmd.c (print_address_symbolic): New arg is the prefix
+ to print if a name is printed.
+ (print_address_demangle): Honor "set print address" now.
+ Use new arg above to improve spacing of output.
+ * valprint.c (val_print): When printing function pointers,
+ print symbolic form too.
+ * breakpoint.c (breakpoint_1): Use new print_address_symbolic.
+
+Mon Jul 8 19:02:46 1991 John Gilmore (gnu at cygint.cygnus.com)
+
+ * core.c (memory_error): Reword error msg to mislead less.
+
+ * mips-pinsn.c (print_insn_arg 'd'): Print $ with reg name.
+
+ * mipsread.c (read_mips_symtab, read_the_mips_symtab,
+ parse_partial_symbols): Use newer BFD internals (external_filehdr
+ and external_aouthdr), byte-swap the fields that we care about
+ before using them, and make the file header data local to
+ read_the_mips_symtab rather than global.
+
+Sat Jul 6 01:34:15 1991 John Gilmore (gnu at cygint.cygnus.com)
+
+ * ns32k-opcode.h (movmw, movmd): Fix opcodes. Bug fix
+ from Rune Nerg}rd <runene@ifi.uio.no> on 5 Jul 1991.
+
+ * main.c (command_line_input): Flush stdout and stderr
+ before every call to readline. This reportedly fixes a bug
+ that comes up in Sys V running emacs-gdb and/or xxgdb,
+ when stdin/out are pipes or sockets.
+
+Thu Jul 4 14:47:06 1991 John Gilmore (gnu at cygint.cygnus.com)
+
+ * configure.in, Makefile.in: Avoid rebuilding "depend" as much.
+ Avoid declaring Makefile dependencies, because GNU Make stupidly
+ tries to update it if we do.
+
+ * coffread.c: Revise for minor changes to bfd internal coff
+ indexes.
+
+ * configure: If -template= is given a relative path, make it
+ absolute before recurring in subdirectories.
+
+ * configure, configure.in, Makefile.in: Install "configure" script
+ as replacement for config.gdb.
+ * config.gdb, Makefile.dist, Makefile.sdir: Remove
+ * README: Update for configure, mostly. FIXME.
+
+ * Add dec3100 as equivalent to littlemips. Indicate in all host &
+ target config files that they are for the host. When the lines
+ get copied into the Makefile, this makes it more obvious what's
+ up.
+
+Mon Jun 24 23:49:07 1991 John Gilmore (gnu at cygint.cygnus.com)
+
+ * sparc-opcode.h (trap opcodes): Avoid leading spaces or
+ tabs, which end up in the disassembler output inadvertently.
+
+Wed May 29 23:01:03 1991 John Gilmore (gnu at cygint.cygnus.com)
+
+ Make it compile cleanly in an ANSI GCC2 environment.
+
+ * blockframe.c: <stdio.h>
+ * cplus-dem.c: free takes a void *, ifdef __STDC__
+ * dbxread.c (read_huge_number): avoid gcc2 bug hoisting calc of
+ LONG_MAX/radix.
+ * defs.h (alloca): Avoid doing anything if alloca already def'd.
+ * stddef.h, stdlib.h: Remove these files.
+ * symtab.c: Avoid declaring qsort, close.
+ * symfile.c: Avoid declaring close.
+ * utils.c (vprintf): Declare "ap" arg as proper va_alist.
+ * sparc-tdep.c: Avoid including lots of Sun-host-specific files.
+
+ Assorted other changes.
+ * dbxread.c: include "libaout.h", not "liba.out.h".
+ * printcmd.c (print_frame_args): Set recurse properly for
+ indentation of struct and array parameters.
+ * valops.c (value_cast): Allow cast to void.
+ * infrun.c (resume): If NO_SINGLE_STEP, call machine dependent
+ single_step() in a target-independent fashion.
+ * sparc-tdep.c (single_step): Don't call ptrace ourselves, just
+ set up to be ready to continue. This makes us target independent.
+ * infptrace.c (child_resume): Remove call to single_step; now
+ can single step a SPARC target of any kind.
+
+Wed May 22 18:18:24 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
+
+ * Makefile.dist, doc/gdb.texinfo, doc/*-m4.texinfo: split up GDB
+ docn into separate sections---basically chapters, plus two loose
+ pieces that can be configured to go in different places. This
+ allows GNU m4 to preprocess the manual without coredumping.
+
+ * Makefile.dist: tell TeX where to find texinfo.
+
+Mon May 20 12:15:04 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
+
+ * Makefile.dist, doc/gdb.texinfo: respectively create, and use,
+ the new target "rdl-apps.texinfo" which captures the Makefile
+ variable that records where to find the Readline libraries.
+
+Sun May 19 05:36:59 1991 John Gilmore (gnu at cygint.cygnus.com)
+
+ * tahoe-pinsn.c: #include "tahoe-opcode.h", not "opcode.h".
+ * tm-tahoe.h (FIX_CALL_DUMMY): Ignore more parameters.
+ * defs.h (const, volatile): Only define if not already defined.
+ * Makefile.dist (gdb.tar.Z): Create doc subdir w/out CVS/RCS crud.
+
+ * README: Update for release 3.95.
+ * config.gdb: Don't create readline dir in subdir builds.
+ * main.c: Include with "..." form for non-system include files,
+ so "gcc -MM" for "make depend" works.
+ Include readline files with "...h" rather than <readline/...h>.
+ * mipsread.c: Include "ecoff.h" rather than "intel-coff.h".
+
+ * coffread.c: Undo minor damage done by Rich Pixley. Use
+ different internal and external representations of COFF
+ data structures. Use new BFD routines for swapping them in and
+ out.
+ * symfile.c (free_named_symtabs): Avoid freeing file names that
+ are null or empty. Old i960 tools seem to produce files that
+ claim to have empty names, causing each successive file read
+ to blow away the previous one.
+ * sparc-xdep.c (deferred_stores): Repair minor damage by Rich.
+ Move deferred_stores to top of file, but don't separate its
+ #define's from its variable. Add commentary.
+ * Makefile.dist: Fix Rich damage; undo "configure" changes in
+ favor of keeping the (working) config.gdb. Move readline
+ library up a notch.
+
+Fri May 17 12:49:56 1991 Per Bothner (via gnu at cygint.cygnus.com)
+
+ * dbxread.c (read_struct_type): Try to handle g++ version 1 MI
+ debug info.
+ * infptrace.c (fetch_registers): no result, since now void.
+ * tconfig/news: target depends on m68k-tdep too.
+
+Fri May 17 14:40:14 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
+
+ * Makefile.dist: added readline/inc-*.texinfo to dependencies for
+ gdb.dvi target
+
+ * readline/inc-history.texinfo, readline/inc-readline.texinfo:
+ applied various small fixes due to or inspired by RMS comments
+
+ * doc/gdb.texinfo: finished using all RMS comments, save those for
+ appendices on readline and cmd history (which are in other source
+ files)
+
+Thu May 16 18:06:05 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
+
+ * doc/gdb.texinfo: (1) Updated w/ref to RMS comments through
+ chapter 9; (2) documented 'break' command's menu mode for
+ overloaded names, in response to hgs problem report C++ p-31
+
+Wed May 15 11:02:48 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
+
+ * doc/gdb.texinfo: (1) better introductory example; (2) more
+ consistent use of @code, @samp, @file, @kbd throughout; small
+ cleanups to first three nodes; (3) new "Contributors" node;
+ (4) Appendix, Renamed Commands; (5) divert specialized startup
+ instructions to "Targets" chapter for generic manuals, while
+ leaving them up front for manuals specific to specialized
+ environments; (6) apply fixes from RMS comments through chapter 4.
+
+ * pretex.m4: modify explanatory text slightly (and redefine
+ "regexp") to keep GNU m4 from complaining. (It still crashes
+ later, but one step at a time...)
+
+Wed May 15 10:32:12 1991 John Gilmore (gnu at cygint.cygnus.com)

+ before checkin
+
+ * gdbint.texinfo: added instructions on generating gdb.info* files
+ locally for release. These are ordinary info

+ Makefile)---but due to use of texinfo 2, can't count on makeinfo
+ to generate these, so we distribute them already formatted.
+
+ * gdb.texinfo: included full Info node and menu crud (as generated
+ by C-u M-x texinfo-master-menu using the texinfo-2 elisp code).
+
+ * Makefile: updated "gdb.dvi" target to use M4 preprocessor;
+ put in comments-for-future gdb.info target (one day makeinfo will
+ work again).

+ print object.

+
+ * valprint.c: introduce "set p", "set pr", "show p" and "show pr" as

+
+ * symfile.h (free_named_symtabs): Rename from free_named_symtab.
+ * symfile.c (clear_symtab_users_once, cashier_psymtab,
+ free_named_symtabs): Move these routines from symmisc.c.

+ * target.c (dummy_target): Permit add_syms_addr_command.
+
+Sat Apr 13 14:46:07 1991 John Gilmore (gnu at cygint.cygnus.com)
+
+ Permit symbols to be superseded when new symbol files have
+ been read in, particularly for VxWorks.
+
+ * dbxread.c (read_dbx_symtab): Allow N_SOL to cleanly take us back
+ to the main file, as well as to include files. Also, put global
+ functions into the global psymtab, to make "i fun" work.
+ (end_psymtab): Free named symtabs and psymtabs for a file, once a
+ new psymtab for it has been read.
+ * coffread.c (end_psymtab): Free named symtabs and psymtabs for
+ a file, once a new symtab has been read for it.
+ * mipsread.c: FIXME. We need to do the same for MIPS, but it
+ looks harder to determine the top-level block before it's been
+ queued to the psymtab list.
+
+ * symfile.c (symbol_file_add): Use filtered printing and wrap it.
+ If we have wiped out any old symbol tables, clean up at end of
+ symbol reading.
+ (symbol_file_command): Don't reference symfile_fns if it's zero.
+
+ * symtab.h (GLOBAL_BLOCK, STATIC_BLOCK, FIRST_LOCAL_BLOCK): New
+ defines for the blocks of a blockvector that contain global and
+ file-static symbols and the first of the smaller scope contours.
+ * symtab.c (lookup_symbol, find_pc_symtab, find_pc_line,
+ decode_line_1, make_symbol_completion_list): Use the above.

+
+ * symtab.c (list_symbols): Process the first symbol of the
+ static psymbols list.
+ (types_info): Restore this function from its untimely #if 0.
+ It's not perfect, but it is better than nothing.
+ (_initialize_symtab): Restore "info types".
+
+Thu Apr 11 05:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
+
+ * m68k-stub.c: Remote stub for 680x0's, created from
+ rem-m68k.shar (which is removed).
+ * nindy-share/{Makefile,Onindy.c,blout.h,env.h,nindy.c,ttyflush.c}:
+ Remove RCS log stuff now that we use CVS and it blows our diffs.
+
+Wed Apr 10 14:18:06 1991 John Gilmore (gnu at cygint.cygnus.com)
+
+ * symmisc.c (free_named_symtab): Make it work, in its current
+ kludgy fashion. Change result to indicate if we blew away bkpts.
+ * dbxread.c (end_symtab): Accumulate result from
+ free_named_symtab and print warning if we blew user's state.
+ * symfile.h: free_named_symtab now returns an int.
+
+Mon Apr 8 23:57:43 1991 John Gilmore (gnu at cygint.cygnus.com)
+
+ * dbxread.c (dbx_symfile_read): Initialize psymbol list if this
+ is the first symbol read, even if not mainline.
+ (dbx_psymtab_to_symtab): symfile might be zero, cope.
+ * exec.c (exec_ops): Add_syms_addr is valid in our tvec.
+ (set_section_command): New command ("section xxx yyy" -- should
+ be renamed to "set section xxx yyy" FIXME) which sets the
+ base address of a section of the exec file, overriding the
+ virtual address that BFD reports.
+
+Fri Apr 5 17:14:39 1991 John Gilmore (gnu at cygint.cygnus.com)
+
+ * exec.c: Add add_syms_addr_command to exec_ops, so you can
+ load symbols at any address while examining an exec file.
+
+Thu Apr 4 10:09:35 1991 John Gilmore (gnu at cygint.cygnus.com)
+
+ * tm-i386v.h (FLOAT_INFO): Don't define it, since the code
+ for printing the float info is host-dependent, not
+ target-dependent. FIXME.
+ * i386-pinsn.c: Move #includes to top, remove useless ones.
+ * i386-tdep.c: Don't bother including <.../reg.h> since we
+ don't use it (and it doesn't exist on host systems).
+
+ * ieee-float.c (ieee_extended_to_double): Convert NaN to Inf.
+ Convert negative numbers properly.
+ (ieee_test): Make numbers really random; fix format arg.
+
+ * infcmd.c (attach_command, detach_command): Don't repeat on CR.
+ * core.c (core_detach): Unpush core_ops, which might not be on
+ top. We used to just pop the top, which broke things. Don't
+ need dont_repeat() any more.
+ (core_file_command): Psst! Don't repeat it.
+ * remote-nindy.c (nindy_detach): Don't need dont_repeat() now.
+ * expprint.c (print_subexp): Avoid switch fallthru on
+ BINOP_ASSIGN_MODIFY, so we can print += and such.
+ * frame.h: Fix typo.
+ * inflow.c (kill_command): After killing inferior, print our
+ current frame in the core file, if we have one.
+ (generic_mourn_inferior): When inferior dies, either select
+ the current frame (in the new target, e.g. core file), or
+ set both the current and selected frames to NULL.
+
+ Changes from Peter Schauer.
+
+ * infptrace.c: Avoid <sys/ptrace.h> on USG.
+
+ * Make all file names fit in 14 characters (sigh and damn!):

+
+ * command.c (user_info_1, user_info): New command for listing
+ the user-defined commands.
+
+Wed Apr 3 15:00:26 1991 John Gilmore (gnu at cygint.cygnus.com)
+
+ * dbxread.c (really_free_pendings): Clear file_symbols
+ and global_symbols after freeing them; otherwise, running
+ this function twice (if it appears twice on the cleanup
+ chain), we try to free things twice.
+
+ * dbxread.c (read_dbx_symtab): Calculate end_of_text_addr
+ based on text_addr (the address of text in core), not on addr (the
+ offset between text in the .o file and in core). This change
+ is from Peter Schauer.
+
+ * main.c: Define ALL_CLEANUPS as a cast of zero.
+ (return_to_top_level): Use it.
+ (main): Do all cleanups after each command run as part
+ of the gdb startup sequence. Also do all cleanups before
+ entering the command loop, and every time we exit the command
+ loop and reenter. Before, the cleanups from the startup sequence
+ were being left undone until the first error!
+ (command_loop): Rename do_nothing cleanup to command_loop_marker
+ so we can see it easily when examining the cleanup chain.
+ (init_signals): Add another do_nothing for signal handling.
+ (quit_command): Only try to kill target if it has execution.
+ Problems in the target stack got us into a state where
+ inferior_pid was nonzero but none of the targets had execution.
+ In this state you couldn't exit gdb.
+
+ * dbxread.c: Two changes from Peter Schauer.
+ (echo_command): Fflush output after an echo command.
+ (show_history): Pass all args to cmd_show_list.
+
+ * utils.c (init_malloc): Call mtrace to turn on tracing
+ if the environment variable MALLOC_TRACE is set to a file name.
+ * mtrace.c: Add source file which provides a log of every malloc,
+ free, and realloc to a trace file.
+ * mtrace.awk: Add source file which analyzes the trace file.
+ * Makefile.dist (GNU_MALLOC, MALLOCSRC): Add mtrace.{c,o,awk}.
+ (VERSION): Roll to 3.94.3.
+
+ * breakpoint.c (breakpoint_1): Add a space to "i watch" output.
+ (check_duplicates): Don't bother with watchpoints.
+ (set_raw_breakpoint): Comment about danger of this routine.
+ (watch_command): Parse and eval all args before calling
+ set_raw_breakpoint.
+
+ * solib.c (find_solib): Avoid error in referencing memory to
+ see if any more shared libraries have been added. This is
+ particularly useful if the target has terminated. Bug reported
+ by Peter Schauer.
+
+ Changes from Peter Schauer <pesrem@regent.e-technik.tu-muenchen.de>
+ in bringing up 3.94.2 on the Sun-3.
+
+ * Makefile.dist: Include CFLAGS in rule for cplus-dem.o.
+ * breakpoint.c (enable_breakpoint): Check for valid watchpoint
+ expression (in scope) before reenabling watchpoint.
+ * signame.c (init_sigs): Add missing declaration of i, fix
+ sys_siglist declaration.
+ * source.c (list_command): Fixed range computation to use
+ lines_to_list ().
+ * stack.c (backtrace_command): Do not allow command if target has
+ no stack, print informative error message.
+ * target.c (target_command): Do not write into command line
+ because this fails if the target command is used in a user defined
+ command. [This change was enhanced by gnu to support any-
+ unique-prefix matching on target names.]
+ * valops.c (value_struct_elt): Avoid infinite loop on an
+ erroneous attempt to print the member of function (try p main.p).
+
+Mon Apr 1 17:05:45 1991 John Gilmore (gnu at cygint.cygnus.com)
+
+ * expread.y (name_no_typename): Avoid reduce/reduce errors
+ caused by ambiguity in handling NAME_OR_INT and NAME_OR_UINT.
+ Since the GDB parser really doesn't use name_no_typename in a
+ name-only context, the parser can't tell the diff between
+ names and numbers here. Avoid allowing a name_no_typename
+ to be a NAME_OR_*INT to resolve the conflict.
+
+Sun Mar 31 20:12:07 1991 John Gilmore (gnu at cygint.cygnus.com)
+
+ Bugfixes from Mark Fox (markf@wrs.com) (test=testField.c):
+
+ * valprint.c (val_print_fields): bitfield printing didn't handle
+ byte order. Indirect through a few more fns to cope.
+
+ * values.c (modify_field): also cope with byte order.
+
+Sat Mar 23 10:02:21 1991 John Gilmore (gnu at cygint.cygnus.com)
+
+ Cleanup for release 3.94.2:
+
+ * Makefile.dist: Pull REMOTE_OBS. Fix saber includes for BFD
+ include files. Roll version to 3.94.2.
+
+ * coffread.c (init_stringtab): Read length into unsigned char
+ array before swapping; don't assume 32-bit longs.
+
+ * target.c (target_info): Don't bother with get_sym_file, just use
+ the symfile global variable.
+ * symtab.h, symfile.c (get_sym_file): Delete it.
+
+ * dbxread.c (dbx_symfile_init): Don't depend on long == 4 bytes.
+ (define_symbol): Set symbol line number to 0 if not gcc-compiled.
+ (read_type): Replace one more error() with complain().
+
+ * mipsread.c (parse_partial_symbols): Replace printf with complain.
+
+ * i960-tdep.c: Fix copyright attribution.
+
+ * config.gdb: Quote all backquotes in doublequotes. You can
+ quote me on that. BSD 4.4 shell found this one.
+
+ * infptrace.c (throughout): The third argument to ptrace is an
+ int *, not an int.
+
+ * infrun.c (wait_for_inferior): When program has terminated, we
+ have to call target_terminal_ours before we pop that target off
+ the stack (e.g. before a call to target_kill or
+ target_mourn_inferior). This fixes problem where a program
+ terminates, then GDB stops for (tty output) and you have to type
+ "fg" to the shell to resume it. FIXME: This code for what to
+ do after termination really should be in normal_stop instead.
+
+ * gdbcore.h (read_memory_check): Change declaration; it changed
+ names months ago.
+
+ * terminal.h: Include <sgtty.h> before <sys/ioctl.h>, since in BSD
+ 4.4 prereleases, this avoids a bug in their sgtty compatability
+ support.
+ * remote.c: Use terminal.h rather than hand-rolling the same.
+
+ * signame.c, signame.h (psignal): Arg is unsigned, not int.
+ * utils.c (strsave, strstr): Fix arg types.
+ * valprint.c (val_print): lint
+
+ MIPS symbol table support from Per Bothner:
+
+ * symfile.c (symtab_fns): Remove initializer table that needs to
+ be hacked for each new symbol file format supported.
+ (add_symtab_fns): New function, chains symbol table
+ handlers into the global list.
+ (symfile_init): Search this list.
+ * symfile.h: Add next pointer, declare add_symtab_fns.
+ * coffread.c (_initialize_coffread): Call add_symtab_fns.
+ * dbxread.c (_initialize_dbxread): Call add_symtab_fns.
+
+ * mipsread.c (psymtab_to_symtab_1): return void instead of (struct
+ symbol *). Thus, we no longer need the hack to trash
+ pst->filename. Good, since that hack confused code in symfile.c!
+
+ (reorder_symtabs, destroy_all_symtabs): Removed static
+ all_symtabs, which was used to qsort symtabs in reorder_symtabs.
+ Instead, the latter now uses a temporary array (stack-allocated
+ from an obstack, and then freed).
+
+ (parse_symbol): Added a hack to fix up BLOCK_{START,END} if they
+ haven't been set in the outermost stBlock of a procedure. This was
+ a problem with f77 binaries on Ultrix 4.?.
+
+ (new_symtab, new_symbol, new_type): Continue changing code to use
+ obstacks more and otherwise conform to dbxread internal style.
+ Made the free_code of symtabs be free_linetable (as in dbxread)
+ instead of free_contents. This implies memory leaks when reading
+ a new symbol table, until the conversion is finished. Did change
+ (struct symbol) and (struct type) to be allocated on the
+ symbol_obstack. Blocks and blockvectors are among the things
+ still "leaking."
+
+ * mipsread.c (parse_partial_symbols, parse_fdr): It hasn't been
+ tested much, but it solved one problem (reported by Meissner), and
+ cleans up some other things. The problem happened when an
+ included file contains actual code (functions) and not just
+ definitions. The mips coff is a little inconvenient there, since
+ it may cause a procedure to be mapped to the wrong psymtab.
+
+ * mips-tdep.c (heuristic_proc_desc): Minor cleanup.
+ * mips-xdep.c (fetch_core_registers): Minor cleanup. FIXME,
+ this will need work for the new core paradigm.
+
+ Opcode patches from the net:
+
+ * mips-opcode.h: fix incorrect disassembly of the mfc1, cfc1, and
+ ctc1 instructions. Also, the cvt.d.w and cvt.s.w instructions were
+ missing altogether - they are added here. From Bruce Bauman.
+ * mips-opcode.h: The low mask for C0 instructions was too small.
+ From Garrett Lau. I modified the fix to check the entire 32-bit
+ opcode.
+
+ * ns32k-opcode.h: Fix opcodes for deiw and deid. From Bruce
+ Bauman.
+
+Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
+
+ Roll in changes from Per Bothner (Tue, 25 Sep 90 11:11:04):
+
+ * dbxread.c (read_type): Pointer subtraction (value_sub in
+ valarith.c) sometimes failed because the types of the
+ pointers being subtracted were not identical.
+ These differed because dbxread.c was allocating pointer types
+ using dbx_alloc_type+smash_to_pointer_type instead of
+ lookup_pointer_type. I failed to find a justification for the
+ former, so I changed it to use the latter. Similarly, I
+ replaced smash_to_function_type by lookup_function_type,
+ and smash_to_reference_type by lookup_reference_type.
+
+ * mipsread.c (parse_symbol, upgrade_type, parse_procedure,
+ _initialize_mipsread): corresponding changes.
+
+ * symtab.c (smash_to_{pointer,reference,function}_type): eliminate.
+
+ * source.c (mod_path): Do tilde_expand on each component of the path,
+ rather than on the (list of) paths as a whole.
+ (print_source_lines): Set first_line_listed in addition to
+ current_source_symtab and current_source_line. If the source was
+ not findable, after a "dir" command to fix the problem,
+ a "list" would get the wrong lines.
+
+ While I was there... (gnu):
+
+ * dbxread.c (read_type): Change error to complaint.
+
+Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
+
+ First attempt at detailed understanding of symbol table memory alloc.
+
+ * dbxread.c (dbx_symfile_read): Free our string table if we
+ aren't the mainline. Free the "info" struct since we're done with
+ it.
+ (init_psymbol_list): Free any previously allocated psymbol lists.
+ (): FIXME: Should realloc-down the psymbol lists when done reading
+ the main symbol file?
+
+ * symmisc.c (free_symtab): Free fullname field too.
+
+ * xm-hp300hpux.h (USG): #undef then #define so Makefile can -D.
+ (REGISTER_ADDR): Make result type unsigned int.
+
+ * xconfig/{i386*,hp300hpux,altosgas,altos}: All config files that
+ define REGEX must also define REGEX1 (its dependency).
+
+Tue Mar 19 21:28:57 1991 John Gilmore (gnu at cygint.cygnus.com)
+
+ * tconfig/i960: No longer works, points you at vxworks960 or
+ nindy960.
+
+ * xgdb.c, XGDB-README: Remove file. Users can get the much
+ better xxgdb.
+ * Makefile.dist: Remove all trace of xgdb.
+
+ * breakpoint.c (breakpoint_1): Pass demangle arg to
+ print_address_symbolic.
+ (clear_breakpoints): Remove unused function.
+ (breakpoint_re_set_one): Guts of breakpoint_re_set.
+ (breakpoint_re_set): Use catch_errors to do them all anyway.
+
+ * gdb-int.texinfo (Host versus Target): Add section on what is
+ a "host" feature versus what is a "target" feature.
+
+ * infcmd.c (path_command, path_info): Handle the PATH variable
+ (object search path) as conveniently as the source search path.
+ * environ.c (set_in_environ): Set some vars in GDB's environment,
+ in addition to the child's. PATH, G960BASE, G960BIN for starters.
+ * source.c (mod_path): New function, from guts of
+ directory_command, modifies a path. Used by path_command.
+ (directory_command): Call it.
+ * defs.h (strsave): Declare.
+
+ * utils.c (sevenbit_strings): Add new printing option.
+ (printchar): Use it.
+ (strsave): Provide this handy helper routine.
+ (set_width_command): Rename set_screen_width_command.
+ (_initialize_utils): "set screen-width" => "set width";
+ "set screen-height" => "set height"; add sevenbit-strings.
+
+ * infcmd.c (do_registers_info): Print floating point registers
+ in raw hex as well as float format, regardless of whether it is
+ a "virtual" convertible register.
+ * tm-sparc.h (PRINT_REGISTER_HOOK): Print every pair of float
+ regs as a double, just in case it's being used that way.
+ * values.c (unpack_long): Comment on array/function coercion.
+ (unpack_double): Argument is in target byte order now. For
+ integer arguments, just call unpack_long and float the result.
+ * m68k-tdep.c: include defs.h for "const" handling.
+ * remote-nindy.c: Use ieee-float stuff.
+ (nindy_fetch_registers): Unpack double regs to host double, then
+ to extended.
+ (nindy_store_registers): Pack extendeds to host double, flip
+ around by misusing unpack_double, send as target double.
+
+ * tm-vxworks68.h (FRAME_CHAIN): Handle current frame pointer of
+ zero, as when stopped at the first instruction of a process.
+
+ * blockframe.c: Fix filename in comment (param.h => tm.h).
+ * sparc-tdep.c (skip_prologue): More explicit nudging comments.
+ * tm-68k.h: Fix typos.
+
+Fri Mar 15 01:09:34 1991 John Gilmore (gnu at cygint.cygnus.com)
+
+ Changes from a bringup on the DEC Vax under Ultrix 4.0.
+
+ * coredep.c (fetch_core_registers): Pass end-address of register
+ section to register_addr as expected. Don't call supply_register
+ if we'd just pass it garbage.
+
+ * dbxread.c (read_dbx_symtab): Skip N_NSYMS on Ultrix.
+
+ * exec.c (xfer_memory): Use boolean xfer_fn result, not int.
+
+ * target.c (push_target, target_info): Cast enums to int for < or
+ > comparison.
+
+ * stack.c (print_frame_info): Identify source file & line
+ even if we can't print it.
+
+ * xm-vax.h (MISSING_VPRINTF): No longer missing in Ultrix V4.0.

+ doubles and various target IEEE extendeds.
+ * m68k-xdep.c: Eliminate assembler code for extended floats.
+ * xconfig/{3b1,altos,altosgas,hp300bsd,isi,news,news1000,sun2os3,
+ sun2os4,sun3,sun3os3,sun3os4}: Eliminate use of m68k-xdep.o.
+ * tm-i960.h, tm-68k.h (REGISTER_CONVERT_TO_VIRTUAL,
+ REGISTER_CONVERT_TO_RAW): Use ieee_extended_to_double and
+ double_to_ieee_extended.
+ * i960-tdep.c: Define ext_format_i960.
+ * m68k-tdep.c: Define ext_format_68881.
+ * sparc-tdep.c: Define ext_format_sparc, though unused.
+ * Makefile.dist (HFILES): Add ieee-float.h.
+ * inftarg.c: #include "ieee-float.h" for the REGISTER_CONVERT
+ macros.
+
+ Obsolete the "coffstrip" program in favor of using BFD's strip.
+
+ * nindy-share/coffstrip.c: Remove file.
+ * nindy-share/nindy.c (coffstrip): Routine to run bfd_strip.
+ * Makefile.dist: Remove references to nindy-share/coffstrip.c.
+ * tconfig/nindy960: Remove reference to coffstrip.o.
+
+ * Makefile.dist: Roll version number to 3.94.1 (not yet final).
+
+Wed Mar 6 09:56:45 1991 John Gilmore (gnu at cygint.cygnus.com)
+
+ * symfile.h: Add symfile_bfd, common between dbxread and coffread.
+ * dbxread.c: Remove static symfile_bfd.
+ * infcmd.c (do_registers_info): Add PRINT_REGISTER_HOOK, though
+ it is not used yet.
+ * inftarg.c (child_detach): Pop the child_ops vector if the
+ detach is successful.
+ * remote-nindy.c (nindy_create_inferior): Don't push a new
+ nindy_ops since nindy uses the same one for execution and memory
+ examination anyway.
+ * core.c (core_ops): Use child_attach and child_create_inferior
+ rather than default attach and create_inferior functions.
+
+ Handle floating point registers in core files.
+
+ * sparc-xdep.c (fetch_core_registers): Rewrite for float support.
+ * sun3-xdep.c (fetch_core_registers): Rewrite for float support.
+ This version untested since BFD doesn't yet support sun3 core
+ files.
+ * hp300hpux-xdep.c: Rewrite fetch_core_registers to new calling
+ conventions. Fix comments and style. This version has not
+ been compiled yet, since we have no HP inhouse.
+ * core.c (get_core_registers): Look for two sections, ".reg"
+ and ".reg2", and pass both to fetch_core_registers sequentially.
+
+ Revise directory path yet again.
+
+ * source.c (forget_cached_source_info): Not static any more.
+ (init_source_path): New default source path is "$cdir:$cwd".
+ (dir_command): Handle variable arguments ($cdir, $cwd).
+ (source_info): Print "Compilation directory" rather than
+ "Originally compiled in" to remind people of $cdir.
+ (openp): If the path contains $cwd, use current directory.
+ (open_source_file): If compilation directory is known, replace
+ first $cdir in path with the compilation directory.
+ (print_source_lines): Even if we can't print the lines, set the
+ current symtab and line for future commands like "info source" or
+ "breakpoint". Also, error message now contains the file name,
+ line number, and file access error message.
+ (_initialize_source): Fix help text to describe changes.
+ * main.c (cd_command): Forget cached source info when we chdir.
+ * utils.c (strstr): Add simple implementation.
+
+Tue Mar 5 01:41:40 1991 John Gilmore (gnu at fowanton.cygnus.com)
+
+ * coffread.c (read_one_sym, init_linetable, init_stringtab):
+ Byte-swap COFF symbol tables if necessary when reading them in.
+ Use complain() to replace error message in one spot. Needs
+ corresponding change in bfd/coff-code.h to make some symbol
+ swapping routines non-static.
+
+Mon Mar 4 00:53:40 1991 John Gilmore (gnu at cygint.cygnus.com)
+
+ Merge changes from Eirik Fuller, for UTek.

+ remote-vx.c, source.c, standalone.c, stuff.c, sun386-xdep.c,
+ symmetry-tdep.c, symmetry-xdep.c, umax-xdep.c, utils.c: Eliminate
+ declarations of errno.
+
+ * remote-eb.c: Define B19200 and B38400 as EXTA and EXTB.
+
+ * remote-vx.c: Include <sys/time.h> for UTek; Sun gets it via
+ <rpc/rpc.h> and <rpc/types.h>.
+
+Sat Mar 2 15:47:55 1991 John Gilmore (gnu at cygint.cygnus.com)
+
+ * i960-tdep.c (examine_prologue): Add new argument limit,
+ which stops the scan at the end of the prologue, or at the PC.
+ This fixes a problem where it walks down into the code for the
+ user's statements if that code looks like function prologues.
+ Mark Fox and I have been bouncing this code back and forth, making
+ small changes to it. Callers changed to match.
+
+Tue Feb 26 01:47:07 1991 Cygnus John Gilmore (cygnus at yuba)
+
+ Cleanup for gdb-3.94 release final:
+
+ * Makefile.dist: Remove remote-vx.c, remote-nindy.c, and all
+ the .c files from vx-share and nindy-share, from the various
+ macros, since they are not found via ALLDEPFILES.
+ (SFILES): Add tm-i960.h.

+ ALLDEPFILES_SUBDIR. List all the nindy and vxworks subdir files
+ in the SUBDIR list.

+ (gdb.tar.Z): Use ALLDEPFILES_SUBDIR as well as SFILES_SUBDIR.
+
+Mon Feb 25 16:02:35 1991 Cygnus John Gilmore (cygnus at oldman)
+
+ * am29k-tdep.c: Add contribution line.
+ (examine_prologue): Cache information about function prologues in
+ the misc-function-vector to avoid lots of references over the
+ serial line while examining instructions.
+
+ * core.c (core_close): New function made from cleanup_core.
+
+ * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
+ remote-vx.c, remote.c, target.c, target.h,
+ Update target_ops vector to add attach, close, and load entries.
+ Use add_syms_addr_command, not add_file_addr_command, for
+ add_file. Break out close routine from existing code.
+
+ * dbxread.c (really_free_pendings): Don't free pending_blocks;
+ they are in an obstack.
+ (read_dbx_symtab): Relocate end_of_text_addr in the psymtab.
+ Lint.
+ (define_symbol): Add symbol type parameter; change callers;
+ pass type parameter to DBX_PARM_SYMBOL_CLASS macro to allow
+ it to influence the symbol class on the i960.
+ (define_symbol): Swap LOC_CONST's into target byte order.
+
+ * exec.c (exec_close): New function.
+ (exec_file_command): Call it.
+
+ * findvar.c (read_relative_register_raw_bytes): Doc byte order,
+ Fix byte order of frame pointer.
+ (read_var_value): Result of 0 if var's value can't be found,
+ e.g. missing FRAME_ARGS_ADDRESS. Byte-swap LOC_CONST and
+ LOC_LABEL values to target order. Add LOC_LOCAL_ARG.
+ (locate_var_value): Use read_var_value and use its lazy address
+ as the location of the var's value. Lint.
+
+ * i960-pinsn.c (next_insn): Add routine from vxgdb for scanning
+ instructions.
+
+ * i960-tdep.c (arg_address, i960_frame_find_saved_regs): Remove
+ obsolete Intel versions in favor of vxgdb versions.
+ (check_host, byteswap, byteswap_val, reorder_val): Eliminate
+ code dealing with byte order of values, which Intel did in host byte
+ order rather than gdb-4's target byte order.
+ (i960_frame_chain_valid): Move to nindy-tdep.c.
+ (examine_prologue, skip_prologue, frame_find_saved_regs,
+ frame_args_address, leafproc_return, saved_pc_after_call,
+ pop_frame): Add vxgdb versions from Mark Fox.
+ (examine_prologue, frame_struct_result_address): Add code
+ to deal with the saved value of G13 (struct return address
+ pointer).
+ (frame_args_address): Modify Mark's version to prefer the
+ saved value over the current value in the topmost frame.
+ Cache result in the frame info to avoid performance hair in
+ callers.
+ (print_fault): Add gdb960 code for printing faults.
+ (_initialize_i960): Actually call check_host.
+
+ * ieee-float.c (ieee_extended_to_double, ieee_double_to_extended):
+ add stub routines. FIXME, these currently just return zero!
+
+ * infcmd.c (program_info): Use PRINT_RANDOM_SIGNAL.
+ (attach_command): Call target_attach, not target_open, now.
+
+ * infrun.c (normal_stop): Make global, not static, for vx_attach.
+ (child_attach): Rename from child_open.
+ (wait_for_inferior): Use PRINT_RANDOM_SIGNAL. If stop_pc is zero,
+ don't confuse it with a zero step_resume_break_address.
+
+ * inftarg.c (child_detach): Eliminate inferior_pid test.
+ (child_files_info): Clean up message a bit.
+ (child_ops): Use child_attach, not child_open, to attach.
+
+ * mem-break.c: #ifdef out the whole file if BREAKPOINT is not
+ set (e.g. on VxWorks or NINDY). Move read_memory_nobpt from
+ findvar.c to here, since it depends on the contents of the
+ shadow_contents of breakpoints, but keep if #if 0 since it is
+ never called.
+
+ * nindy-tdep.c: New file, contains nindy_frame_chain_valid, moved
+ from i960-tdep.c.
+
+ * printcmd.c (address_info): Handle LOC_LOCAL_ARG. Lint.
+ (ptype_command, display_command): Eliminate have_inferior_p and
+ have_core_file_p in favor of target_has_stack or
+ target_has_execution.
+ (print_frame_args): Handle LOC_LOCAL_ARG. Eliminate duplicate
+ code for actually finding the values of arguments, though we still
+ keep track of the maximum stack offset for use in printing unnamed
+ arguments. Handle missing FRAME_ARGS_ADDRESS.
+
+ * remote-nindy.c (i960_print_fault): Move to i960-tdep.c.
+ (struct nindy_regs): Define registers passed to/from nindy.
+ (nindy_fetch_registers, nindy_store-registers): Translate between
+ nindy and GDB formats for the registers.
+ (dcache_init): Statically allocate the cache, since it was being
+ allocated by a malloc that was never freed anyway.
+ (nindy_create_inferior): Error, not core dump, if no exec file.
+ (nindy_before_main_loop): Use target_load, not target_add_file.
+
+ * remote-vx.c (net_load): Specify large timeout for load
+ requests. Allow user to break out with INTERRUPT.
+ (net_break): Remove useless code, clean up. Change callers.
+ (parse-args, skip_white_space, find_white_space): Clean up arg
+ parsing to cope with quoted strings.
+ (net_wait, net_quit): Never call error, just return status.
+ (vx_read_register, vx_write_register): Cleanup status checking.
+ #ifdef the code based on which CPU we are using (960 or 68k),
+ FIXME, this should be completely general but it isn't yet.
+ (vx_xfer_memory, vx_resume): Cleanup status checking.
+ (vx_run_files_info): Improve message.
+ (vx_load_command): Renamed from vx_add_file_command. Allow load
+ to be interrupted.
+ (net_ptrace): Remove unused routine.
+ (vx_wait): Adopt code from vxgdb960 to cope with broken
+ connections to target machine and prompt to disconnect. Remove
+ debug printouts. Map some EVENT_'s to SIGnals.
+ (add_symbol_stub, vx_open): Print names of object files we found,
+ and "ok" if we read their symbols OK. Clarify output in general.
+ (vx_attach, vx_detach, vx_kill): Add these commands.
+ (vx_convert_from_virtual, vx_convert_to_virtual): Simplify.
+ (vx_run_ops): Turn off all_mem, to avoid spurious msg in the
+ "info files" output, and create_inferior, since we already have
+ an inferior.
+
+ * stack.c (frame_info): Replace Frame_unknown with 0.
+ (print_frame_arg_vars): Handle LOC_LOCAL_ARG.
+ (return_command): Pop until the PC matches as well as the FP,
+ so it works even if the FP is shared with another function,
+ as in "frameless" or "leaf" procedures.
+
+ * symfile.c (load_command): renamed from add_file_target_command.
+ (add_syms_addr_command): renamed from add_file_addr_command.
+ (add_syms_command): Stub to call target_add_syms.
+ (_initialize_symfile): Change command names and descriptions,
+ add-file => add-syms, and load from alias to its own command.
+
+ * target.c (kill_or_be_killed, maybe_kill_then_attach,
+ maybe_kill_then_create_inferior): Default for attempts to start
+ a process, if one is already running, is to ask about killing
+ it and retry if yes.
+ (upstack_create_inferior): #if-0 it, strata obsolete it.
+ (push_target, unpush_target, pop_target): to_close() a target
+ before unstacking it.
+ (target_info): Renamed from target_files_info.
+ (_initialize_targets): Rename "i files" as "i target", accessible
+ under both names.
+
+ * target.h: Improve comments about the target_ vectored routines.
+
+ * tm-i960.h: Remove NINDY-specific stuff to tm-nindy960.h.
+ Convert commenting style to standard GNU style.
+ (DBX_PARM_SYMBOL_CLASS): allow LOC_LOCAL_ARG's to be recognized.
+ (SKIP_PROLOGUE): No longer a no-op.
+ (SAVED_PC_AFTER_CALL): Now handles leaf procedures.
+ (*_REGNUM): Sort register numbers.
+ (REGISTER_BYTES, REGISTER_BYTE, REGISTER_RAW_SIZE,
+ MAX_REGISTER_RAW_SIZE, REGISTER_CONVERTIBLE,
+ REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW): Float regs
+ are now 10 byte extendeds, not 8 byte doubles.
+ (FRAME_CHAIN_VALID): Make this config-dependent, since it differs
+ for nindy versus vxworks targets. FIXME, this should possibly go
+ in the target vector.
+ (EXTRA_FRAME_INFO, INIT_EXTRA_FRAME_INFO): Cache both
+ frame_saved_regs and arg pointer with each frame.
+ (FRAMELESS_FUNCTION_INVOCATION): New leafproc support.
+ (FRAME_ARGS_ADDRESS): Use cached result.
+ (FRAME_ARGS_ADDRESS_CORRECT): New, avoids g14 guessing.
+ (FRAME_FIND_SAVED_REGS): Change arg to subsidiary fn.
+ (PRINT_RAMDON_SIGNAL): Call print_fault.
+ (POP_FRAME): Now works.
+
+ * tm-nindy960.h: Break this off tm-i960.h. NINDY-specific
+ option parsing and startup; STACK_END_ADDR, FRAME_CHAIN_VALID,
+ BREAKPOINT, and DECR_PC_AFTER_BREAK are here.
+ (ADDITIONAL_OPTION_HANDLER): use target_load, not
+ target_add_file.
+
+ * tm-vxworks960.h: Break this off tm-i960.h. VxGDB specific
+ startup; DECR_PC_AFTER_BREAK, and FRAME_CHAIN_VALID are here.
+
+ * valarith.c (value_subscripted_rvalue): Avoid handling
+ floats and doubles specially; it gave alignment errors. Lint.
+
+ * valops.c (value_of_variable, value_of_this): Error if unknown
+ value.
+
+ * valprint.c (print_floating): Bcopy rather than pointer-deref,
+ to avoid alignment problems.
+ (value_print): Handle unknown value address.
+ (cplus_val_print): Two args are ignored; remove them. Change caller.
+ (val_print): Use unpack_long rather than pointer-deref.
+
+ * values.c: Lint.
+ (unpack_long, unpack_double): Use bcopy rather than pointer-deref
+ to avoid alignment problems.
+ (value_being_returned): Error if return value unknown.
+ (set_return_value): Add bogosity warning, FIXME. *
+
+ * TODO: A woman's work is never done.
+
+ * Makefile.dist: Distribute REMOTE_OBS into tconfig files.
+ Separate INCLUDE_CFLAGS for use with lint. Add LINTFILES.
+ Add ieee-float.o to OBS.
+ * tconfig/{nindy960,vxworks68,vxworks960}: Include the desired
+ REMOTE_OBS remote-interface files in the TDEPFILES and TM_FILE.
+ * tconfig/i960: FIXME. Half-merge, produce warning if config'd.
+
+ Changes to generalize the VxWorks RPC protocol slightly, to handle
+ i960 as well as 68000.
+
+ * vx-share/dbgRpcLib.h (VX_SOURCE_STEP): Add.
+ * vx-share/reg.h: Produce i960 regs #ifdef I80960
+ * vx-share/xdr_ptrace.c: Skip FPA registers if 960.
+ * vx-share/xdr_rdb.h: Add SOURCE_STEP struct and xdr decl.
+ * vx-share/xdr_rdb.c: Add xdr_SOURCE_STEP routine.
+ * vx-share/xdr_regs.c: Add xdr_regs, xdr_fp_status, xdr_ext_fp
+ for i960. Change xdr_vectors to xdr_opaques for 68k registers,
+ so they will move in target byte order rather than network
+ byte order (happens to be the same).
+
+Mon Feb 25 03:41:44 1991 John Gilmore (gnu at cygint.cygnus.com)
+
+ * tm-convex.h (END_OF_TEXT_DEFAULT): Remove #if 0'd block.
+
+Sun Feb 24 00:55:53 1991 John Gilmore (gnu at cygint.cygnus.com)
+
+ * am29k-pinsn.c,
+ Add contribution lines to various files, showing where they
+ came from.
+
+ * breakpoint.c (break_insn, check_break_insn_size,
+ read_memory_nobpt): Remove to mem-break.c.
+
+ * xm-*.h, param-no-tm.h, tm-29k.h, valprint.c: Change BYTE_ORDER to
+ HOST_BYTE_ORDER.
+
+ * tm-29k.h (STAB_REG_TO_REGNUM): Warn user if symbol table
+ entry has bad register number. This change is not
+ tested in this release, FIXME.
+
+ * frame.h: Eliminate Frame_unknown in favor of a simple zero.
+ tm-vax.h: Ditto.
+
+ * value.h: Force value's contents field to be aligned to hold
+ at least a double or a long long (if supported). This avoids
+ doing bcopy's in and out of the contents field.
+
+ (step_1): Avoid coredump under obscure circumstances when we
+ have no frame.
+
+ * symtab.h (misc_info): Add field to misc function vector for
+ any kind of cached information the target code desires. AMD
+ 29000 uses this to avoid repeating examine_function_prologue's.
+
+ * coffread.c: Lint. Remove static symfile, read_section_header.
+ core.c (have_core_file_p): Lint: remove.
+ expprint.c (print_subexp): Lint.
+ infptrace.c, valops.c, valprint.c: lint.
+
+ Roll in changes from vxgdb-5.0.1:
+
+ * symtab.h: Comment byte order of each address class. Add
+ LOC_LOCAL_ARG for frame-relative args (960).
+ expread.y: Use LOC_LOCAL_ARG where LOC_ARG is used.
+ symtab.c, symmisc.c: ditto.
+
+ * infrun.c (init_wait_for_inferior): Clear stop_signal.
+
+ * remote.c (remote_resume): Error if resume with a signal.
+
+ * symfile.c (prim_record_misc_function): Clear misc_info.
+ (fill_in_vptr_fieldno): Check stub type of arg.
+
+ * valops.c (value_cast): Avoid looking up names of types whose
+ name we don't know, to prevent coredump. Sun CC produces typedef
+ rtx and the name of *rtx is zero...
+
+Mon Feb 18 21:16:25 1991 John Gilmore (gnu at cygint.cygnus.com)
+
+ Roll in changes from final AMD 29000 port (Tiemann).
+
+ tconfig/am29k: Add COFF_ENCAPSULATE and TARGET=TARGET_AM29K
+ for ../include/a.out.encap.h. This might not work now that BFD
+ is separately compiled. Instead, BFD support for encap will have
+ to translate machine type 29k into the right COFF_MAGIC.
+
+ * infcmd.c: Remove references to inferior_pid that aren't used
+ in actual ptrace calls; use target_has_execution, etc.
+ (have_inferior_p): Remove function.
+ (program_info): Print target info rather than "process number";
+ avoid gratuitous messages unless from_tty.
+ (run_stack_dummy, finish_command): Set proceed_to_finish.
+ infrun.c: Remove inferior_pid refs. Decl & init proceed_to_finish.
+ main.c: Lint. Lose have_inferior_p().
+ inferior.h (have_inferior_p): Remove, lint.
+ (proceed_to_finish): Add flag to ask that all regs be saved
+ by normal_stop, for the few commands that need it, speeding up
+ serial I/O. Add comments to stop_registers.
+
+ * remote-eb.c: Remove newline from breakpoint message we grep
+ for. Never time out when running the user program.
+
+
+
+Wed Feb 13 15:34:40 1991 John Gilmore (gnu at cygint.cygnus.com)
+
+ Roll in changes from vxgdb-5.0.1:
+
+ * dbxread.c (read_dbx_symtab): If we encounter a "FORTRAN COMMON"
+ symbol in its raw form, we are processing an unlinked ".o" file.
+ See if the target environment has assigned it an address, using
+ target_lookup_symbol (VxWorks does), and enter it into the symtab
+ that way.
+
+ * tm-vxworks.h (FRAME_CHAIN, FRAME_CHAIN_VALID): Override usual
+ 68k versions for a simpler version that assumes zero FP at bottom.
+ Fixes bug of truncated stack reports.
+
+ * target.h (target_lookup_symbol): Define this routine's args
+ and result, finally.
+
+ * target.c (nosymbol): Default routine for target_lookup_symbol.
+ (target_default): Default lookup_symbol and call_function too.
+ (files_info): Only print has_all_memory warning if a non-dummy
+ target follows.
+
+ * remote-vx.c (vx_read_register, vx_convert_to_virtual,
+ vx_convert_from_virtual): If target does not have floating point,
+ zero register "values", and avoid doing cross-net conversions.
+ (vx_lookup_symbol): Rename net_lookup_symbol, add to vectors.
+ (vx_open): Rearrange code that attaches to target and reads
+ symbols for all loaded modules, to work if some of the modules
+ are not accessible. Add symbol_stub() and add_symbol_stub()
+ as callbacks from catch_errors(). Allow connect attempt to be
+ interrupted painlessly with ^C (FIXME, there are still some bugs
+ if the interrupt happens during symbol reading.). Print
+ final message with puts_filtered, since symbol messages are
+ now filtered too.
+
+ Misc cleanup:
+
+ * main.c (catch_errors): Only print errstring if non-null.
+ (command_loop): Avoid an ioctl per command to test ISATTY.
+
+ * remote-vx.c (net_load): make static; avoid sophomoric msg.
+ (vx_xfer_memory): Return correct result!
+ (vx_files_info): Indicate whether target has float or not.
+ (vx_lookup_symbol): Complain, not error, if target gone.
+ (vx_open): Print "Connected" msg before disabling immediate-quit.
+ [FIXME: lookup_symbol and vx_open changes need testing.]
+
+ target.c, remote-eb.c, inftarg.c, am29k-opcode.h, target.h,
+ tm-29k.h, tmm-vxworks68.h, symfile.c, gdb-int.texinfo: Add
+ contributor lines and update copyrights to 1991.
+
+ Changes from an attempted H-PUX host port:
+
+ * infptrace.c (PT_ATTACH, PT_DETACH): Handle HP/UX, which
+ defines PT_ATTACH and PT_DETACH but not PT_KILL.
+ * remote-eb.c (eb_open): Misplaced endif kills sysv H/PUX.
+ * remote-vx.c: include <sys/time.h> for HPUX.
+ * hp300hpux-xdep.c (fetch_core_registers): Rewrite old
+ "core_file_command" routine to BFD regime. May not work yet.
+
+ Attempted port of "gdb-3.4 Van Jacobson xgdb" to modern gdb.
+
+ * xgdb.c: Replace X10 version with some VJ version.
+ (FIXME: Its copyright assignment is not on record.)
+ * xgdb.c: Update include files to X11R4 (Xaw crud).
+ (xgdb_display_source, create_text_widget): fix call to
+ get_filename_and_charpos. Rewack source window stuff for X11R4
+ (gleaned from include files, and "nm's" of binary libraries, since
+ I had no doc available).
+ (append_selection, append_selection_word): Disable with FIXME
+ since R4 changed interface here.
+ (create_buttons): Add back the old set of buttons.
+ (xgdb_create_window): Fix call to XtInitialize (&argc not argc).
+
+ * Makefile.dist (xgdb, xgdb-init.c): Update for X11R4 on Suns.
+ Roll VERSION to 3.94 (not yet final though).
+
+Sat Feb 9 09:46:25 1991 John Gilmore (gnu at cygint.cygnus.com)
+
+ * obstack.h (obstack_ptr_grow, obstack_ptr_grow_fast,
+ obstack_int_grow, obstack_int_grow_fast): Eliminate
+ cast on left of assignment, which gives MIPS cc fits and is
+ not Standard C.
+
+ * sparc-pinsn.c (print_insn): Eliminate 'set' test, subsumed by
+ F_ALIAS. Use printf, not fprintf, when not passing a file
+ pointer...
+ (compare_opcodes): Check that identical instructions have
+ identical opcodes, complain otherwise.
+
+ * sparc-opcode.h (st %fsr): Fix opcode "lose" mask. This
+ was reported by Roland McGrath.
+ (unimp): Only match if exactly zero instruction. (Roland)
+ (branches and traps): Generate all variations of these
+ instructions with macros, based on a single call that defines
+ each condition name and its binary representation.
+ (set): Turn on alias bit, to avoid test in sparc-pinsn.c.
+
+ * valprint.c (val_print_fields): Take, and use, format parameter.
+ This means that "p/x struct" again prints the elements in the
+ desired format. Changed callers.
+
+ * stack.c (frame_info): Use filtered output, and indicate wrap
+ points. Remove kludgy formatting designed to avoid line wrap.
+
+ * utils.c (wrap_here): If the line is already full (because
+ we had printed a long indent or long wrapped string), do an
+ immediate newline-and-indent.
+
+ * m68k-pinsn.c (print_insn_arg): Bugfix from
+ ntmtv!thompson@ames.arc.nasa.gov (Mike Thompson): 'bkpt #0'
+ instruction is incorrectly disassembled as bkpt #8.
+
+ * dbxread.c (end_psymtab): Bugfix from Peter Schauer
+ <pesrem@regent.e-technik.tu-muenchen.de>: If you want to set a
+ breakpoint in a *.y file gdb will say Reading in symbols for *.y...
+ and then will dump core (sometimes). I traced it back to an
+ uninitialized symfile_name in psymtab_to_symtab.
+ (const_vol_complaint): Add quotes to message.
+ (define_symbol): Only believe line number if gcc_compiled.
+ Avoid allocating symbol if we will not return it.
+
+ Add target strata support so that newly established targets go
+ into their right place in the target stack (e.g. a new exec file
+ doesn't wipe out the ability to access the running process).
+
+ * target.h, core.c, exec.c, inftarg.c, remote-eb.c,
+ remote-nindy.c, remote-vx.c, remote.c, target.c: Add to_stratum
+ and initialize it properly in all the targets.
+
+ * target.h: Document strata. Change return type of push_target.
+
+ * target.c (nomemory): new function for dummy memory access.
+ (tcomplain): Rename complain, now also used in symfile.c.
+ (push_target): Push targets within strata. New return value shows
+ whether new target is on top of stack or not. Always keep dummy
+ target on stack.
+ (target_files_info): Ignore dummy target.
+
+ * core.c (core_open): Warn user, and skip accessing file, if the
+ core target is not the topmost target in the stack.
+ * remote-nindy.c (nindy_create_inferior): Avoid unpush_target, now
+ already handled.
+
+ * remote-vx.c: Remove vx_prepare_to_store from vxworks memory
+ target_ops, it doesn't belong there since we have no regs there.
+ Change name of target from machine => memory to clarify.
+
+Thu Feb 7 16:32:09 1991 John Gilmore (gnu at spiff.cygnus.com)
+
+ * Freeze version 3.93 for release.
+
+ * Makefile.dist: Handle vx-share and nindy-share subdirs
+ properly when building gdb.tar.Z.
+
+ * symtab.c: lint; add no_symtab_msg to consolidate the messages
+ printed in various places, so I could change just one copy.
+
+ * dbxread.c, coffread.c: Change references to bfd->iostream
+ to cast to FILE *, now that BFD avoids needing types defined
+ in other header files.
+
+Tue Feb 5 21:39:35 1991 John Gilmore (gnu at cygint.cygnus.com)
+
+ * command.c, dbxread.c, expprint.c, infcmd.c, infptrace.c,
+ infrun.c, printcmd.c, remote-nindy.c, source.c, sparc-tdep.c,
+ sparc-xdep.c, symfile.h, symmisc.c, utils.c, valprint.c: Lint
+ (actually gcc -Wall).
+
+ * dbxread.c: Remove first_global_sym, last_global_sym, since
+ they are never referenced.
+
+ * defs.h (baud_rate): Declare.
+ main.c: Define it, and add the -b option to set it.
+
+ * gdb-int.texinfo: Add text on how to define a new host or target
+ architecture, prompted by Per Bothner's questions about MIPS
+ support.
+
+ * gdb.texinfo: Document "complaints". Change doc of -q since
+ gdb no longer prints the copyright and blurb if you specify a file
+ name to be debugged (just like Emacs). Add doc for Nindy-specific
+ command line flags for specifying target serial port and such.
+ Update copyright to 1991.
+
+ * gdbcore.h: Remove a large mass of now-useless crud, since BFD
+ has taken over for us the job of ripping up executable files. The
+ crud caused Per Bothner's port to not compile.
+
+ * infrun.c (normal_stop): Avoid printing "Program exited
+ normally" if we are in batch mode. This allows a GDB which
+ executes a program on a target system, to behave like a Unix
+ command (input from stdin, output to stdout, no extraneous
+ output).
+
+ * main.c (main): Allow additional machine-dependent command line
+ options to be specified with the ADDITIONAL_OPTIONS,
+ ADDITIONAL_OPTION_CASES, ADDITIONAL_OPTION_HELP, and
+ ADDITIONAL_OPTION_HANDLER macros. Also allow machine-dependent
+ processing to occur just before the main loop with
+ BEFORE_MAIN_LOOP_HOOK.
+ (main): If a "core file" argument is specified, and it is not a
+ core file, try it as a process ID to attach.
+ (symbol_completion_function): Attempt to cope with
+ "show screen-" TAB, not very successfully. This needs more work,
+ FIXME.
+ (batch_file): New function, returns whether we are reading
+ commands from an interactive tty on stdin, or from somewhere else.
+ Called by normal_stop since it doesn't get from_tty passed down
+ to it like many commands do.
+
+ * remote-nindy.c: Handle command line options for nindy
+ connection.
+ (nindy_before_main_loop): Prompt user for tty name if they
+ don't specify it before getting to the interactive command loop.
+
+ * tm-i960.c: Add ADDITIONAL_OPTIONS, etc, to handle -O, -brk,
+ and -r command line options. Also add hook before main loop
+ to make it easy to specify a tty.
+
+ * TODO: More things to do, one done.
+
+Mon Feb 4 23:57:39 1991 John Gilmore and Mike Tiemann (at cygint.cygnus.com)
+
+ * dbxread.c: Make complaint() calls pass pointer, not struct.
+ Add complaints about badly formatted C++ type information
+ (const/volatile indicator, and parse errors resulting in
+ error_type). Fix C++ virtual member fn comment.
+ (read_struct_type): Avoid bumping pointer if we got a parse
+ error; this prevents our walking beyond the end of a string.
+ Terminate loop on null char as well as semicolon.
+ (process_one_symbol): Fix the LBRAC fix so that it uses the
+ last previous SLINE, FUN, or SO record's PC address. C++ debug
+ symbols did not have SLINE records in a useful order compared
+ to the LBRAC records.
+ (define_symbol): Handle "catch" records.
+
+ * symtab.c (check_stub_type): Added new complain
+ `stub_noname_complain' and added a consistency check to
+ keep the debugger from crashing when finishing from an
+ exception frame. A real fix will be needed later.
+
+Sat Feb 2 10:43:05 1991 John Gilmore (gnu at cygint.cygnus.com)
+
+ * infcmd.c (attach_command): Make global.
+
+ * Makefile.dist (REMOTE_OBS): Make these compile by default,
+ but make them easy to comment out. Perhaps later they should
+ be enabled by what CPU you configure for? FIXME.
+ (VERSION): Roll to 3.93.
+ (pinsn.o): Remove rule for obsolete file.
+ (dbxread.o,coffread.o,mipsread.o): Use ${srcdir} explicitly.
+
+ Run down a problem that manifested by printing the wrong function
+ name in stack traces of read_ofile_symtab. Turned out that the
+ problem was the SunOS 4.1.1 (and previous) C compiler outputs
+ the LBRAC symbol with an address in the *data* segment, which
+ blew our binary search through the blocks.
+
+ * dbxread.c: Use the complain() facility consistently to bitch
+ about problems in the symbol file we are reading.
+ (finish_block): Add code to check the nesting of the blocks;
+ complain and Procrust them to fit if wrong.
+ (make_blockvector): Check the order of the blocks, complain
+ [but don't cope] if wrong.
+ (process_one_symbol): ifndef SUN_FIXED_LBRAC_BUG, check LBRAC
+ symbols to be sure their PC value is greater than the last SLINE
+ (line number) symbol we've seen, complaining and adopting the
+ SLINE PC value if wrong.
+
+ * symfile.h (struct complaint, complaint_root, complain,
+ clear_complaints): Add.
+ * symfile.c (complain, complaint_root, clear_complaints): Add
+ facility to deal with non-fatal complaints and to regularize their
+ suppression.
+ (symbol_file_add): Clear complaint counters to allow new complaints.
+ (initialize_symfile): Add 'set complaints' and 'show complaints'.
+
+ * dbxread.c (dbx_symfile_read): Remember the address and size
+ of the string table for the main symbol file, so we won't read it
+ more than once.
+ (dbx_psymtab_to_symtab): Fix the check for main symbol file,
+ to avoid reading the string table yet again. Lint.
+ (throughout): Improve filtered output, including word wrap.
+ (read_range_type): Improve Bothner's fix to handle other types too.
+
+ * utils.c: Improve line wrap implementation. Handle unlimited
+ width by making chars_per_line unsigned.
+ (puts_filtered): New, easy, function.
+
+ * defs.h (puts_filtered): add.
+
+ * mipsread.c (compare_symbols, sort_symtab): Remove these fns,
+ call the identical sort_symtab_syms() in symfile.c instead.
+
+ * expread.y: Suggest the `file' command rather than `symbol-file'.
+
+ * command.h (enum var_types): Add zinteger for seroable
+ unsigned integer.
+ * command.c (do_setshow_command): Handle var_zinteger. Restructure
+ nested if's into a switch.
+
+ * breakpoint.c (bpstat_print): If bpstat "print" flag is not set,
+ we did not stop because of a breakpoint (it must have been for
+ some other reason, like a "stepi"), so don't print anything.
+
+ * symtab.c: Include <sys/types.h> all the time. Now that BFD
+ doesn't include <sys/types.h>, old SunOS's require it for
+ <sys/stat.h>.
+
+Sat Feb 2 10:39:15 1991 Per Bothner (bothner@cs.wisc.edu)
+
+ A test port of gdb-3.92.6 to the Sony NEWS.
+
+ * Makefile.dist
+ Don't normally link in remote- or vx stuff.
+ Some of it doesn't compile, and it wastes space for 99% of the users.
+ Remove reference to no-longer-used HAVE_VPRINTF.
+ Fixed BFD_DEP typo to BFD_DIR.
+ * dbxread.c
+ Fix cast in arg to bfd_h_getlong.
+ Make char *prefix be const.
+ Fix how certain range types are mapped into builtin unsigned int types.
+ * infrun.c
+ Remove 2 #includes. They cause errors (on Sony, at least),
+ and aren't needed (they wern't in earlier versions).
+ * printcmd.c
+ print_address_symbolic should never demangle labels
+ (since it prints *assembler-level* labels).
+
+ [This was superseded by the change to printcmd below.]
+
+ * utils.c
+ Add some "volatile" return types to avoid warnings.
+ If MISSING_VPRINTF add vprintf function and not just macro
+ (since vprintf is used in printcmd.c).
+ * valprint.c
+ Unless __GNUC__, use obstack_grow instead of obstack_ptr_grow.
+ (The latter isn't grokked by some PCC-based compilers.)
+
+ [This change is in abeyance, we prefer to fix obstack_ptr_grow.]
+
+ Make chunk size of dont_print_obstack 32*4 instead of default 4096.
+ * nindy-share/coffstrip.c
+ Added some forward declarations (otherwise, gcc complains
+ about implicit extern redefined as static).
+
+Sun Jan 20 02:38:19 1991 John Gilmore (gnu at cygint.cygnus.com)
+
+ Changes inspired by Per Bothner:
+ * printcmd.c (print_address_symbolic): Take additional parameter
+ specifying whether to demangle.
+ (print_address): Pass in asm_demangle to control demangling.
+ (print_address_demangle): New fn, takes explicit arg to control
+ demangling.
+ * utils.c: Add new vars demangle and asm_demangle, and let them
+ be set and shown.
+ (fputs_demangled): If !demangle, just print the argument.
+ (fprint_symbol): If !demangle, just print raw symbol.
+ * valprint.c (val_print): Call print_address_demangle rather than
+ print_address, to cause demangling to depend on the global
+ rather than assembler-level demangling setting.
+ * WHATS.NEW, gdb.texinfo: Document.
+
+ * main.c (show_command): Show all settings if no arg.
+ (initialize_main): Make "info set" the same as naked "show".
+ * command.c (cmd_show_list): Handle prefix commands in the
+ list, and print the name of the setting as well as its English
+ description and value.
+
+ Allow gdb functions to specify where a line should wrap if it
+ exceeds the size of a terminal line. Use it to make the output
+ prettier.
+ * utils.c (set_screen_width_command): New fn, mallocs a buffer
+ of the right size when screen width changes.
+ (set_screensize_command, screensize_info): Remove #if 0'd fns.
+ (wrap_here): New fn, indicates a point in the output where we
+ should wrap the line rather than just letting it overflow at a
+ random place.
+ (fputs_filtered): Implement wrapping.
+ (n_spaces): New fn, returns a pointer to N spaces.
+ (print_spaces_filtered): Use n_spaces.
+ * defs.h (n_spaces): Declare.
+ * stack.c (print_frame_info): Wrap with 4-space indent after
+ fn name and before filename and line number.
+ * printcmd.c (print_frame_args): Wrap with 4-space indent
+ before each argument name is printed.
+ * valprint.c (value_print): Wrap with no indentation before
+ each repetition.
+ (val_print_fields): Wrap with indentation relative to nesting
+ level before each field name.
+ (val_print): Wrap with nesting indentation before array elements.
+ * command.c (do_setshow_command): Avoid extra newlines,
+ wrap with 4-space indent around values printed, end with period.
+ * WHATS.NEW, gdb.texinfo, gdb-int.texinfo: Document.
+
+ * breakpoint.c (breakpoint_1): Implement addressprint for
+ "info breakpoints" display. Change file name and line number
+ format to " at file:nnn" rather than " (file line nnn)".
+ * gdb.texinfo: Document.
+
+
+Fri Jan 18 07:21:25 1991 John Gilmore (gnu at cygint.cygnus.com)
+
+ Frozen for gdb-3.92.6 release.
+
+ README, WHATS.NEW: Update for 3.92.6 release.
+
+ tconfig/{altos, i386v, i386v32, m88k, umax}: Eliminate
+ coffread.o from configs since it is now built by default.
+ tconfig/{3b1, altosgas, arm, convex, hp300bsd, hp300hpux,
+ i386v-g, i386v32-g, isi, merlin, news, news1000, np1, pn,
+ pyramid, symmetry, vax, vxworks68}: Eliminate dbxread.o
+ from configs since it is now built by default.
+
+ Makefile.dist: Update for release 3.92.6. Handle files that
+ have been moved to ../include, ../getopt, or ../bfd. Add
+ saber.suppress and tests directory. Add config.status to
+ the release (it will say "none").
+
+ coredep.c: Minor formatting fixes.
+
+ These changes were made in early December but only checked in now:
+ * nindy-share/Onindy.c, nindy-share/coffstrip.c,
+ nindy-share/nindy.c: lint
+ * nindy-share/nindy.c (ninStopWhy): Don't byteswap the
+ register values coming back from the target; we store values
+ in target byte order everywhere.
+
+Wed Jan 16 19:01:37 1991 John Gilmore (gnu at cygint.cygnus.com)
+
+ * am29k-opcode.h, am29k-pinsn.c: Add 29050 opcodes.
+
+ * valprint.c (cplus_val_print, val_print_fields): New functions,
+ which print C++ objects. They conspire to avoid printing a
+ virtual base class more than once, following all the twists and
+ turns of C++ virtual base rules.
+ (val_print): Call the above rather than do it by hand.
+
+ * symfile.c (symbol_file_add): Only reset symfile_mtime for main
+ symbol file, not for added files like shared libs. This really
+ needs to be generalized to a timestamp per file.
+
+ * core.c (cleanup_core): Avoid coredump if no core file.
+
+ * config.gdb: Accept -host or -target in place of +host or
+ +target.
+
+ * coffread.c (find_linenos): Avoid desupported BFD interface
+ to line numbers. We still read them manually rather than using
+ BFD's "generic" features.
+
+ * gdbrc.tex, threecol.tex: Add GDB reference card and its
+ formatting code.
+ Makefile.dist: Add refcard to OTHERS list for creating tar files.
+
+ * Makefile.dist: Eliminate use of $< in explicit targets.
+
+ * readline/Makefile: Use $< rather than $*.c, which does not
+ include the VPATH in GNU Make.
+
+ * tconfig/i960-bout, tconfig/i960-coff: These are identical
+ copies of tconfig/i960, added for global configuration
+ compatability. All i960 versions can read both coff and b.out.
+
+ * tm-88k.h: Fix multiline macro that lacked \'s. Remove
+ COFF_FORMAT and COFF_CHECK_X_ZEROES since these are now handled
+ automaticaly.
+
+ * TODO: Think of more things to do.
+
+Wed Jan 2 19:09:29 1991 John Gilmore (gnu at spiff.cygnus.com)
+
+ tconfig/{am29k,i960,sun2*,sun3*,sun4*}: Eliminate config
+ of sdb versus dbx debug symbols. Add kludge for 68881 80-bit to
+ 64-bit float conversion.
+
+ tconfig/sun4, tconfig/sun3, xconfig/sun4, xconfig/sun3: Make
+ equivalent to sun?os4 so global config works.
+
+Wed Jan 2 18:20:51 1991 John Gilmore (gnu at spiff.cygnus.com)
+
+ Fix from Eberhard Mattes <mattes@azu.informatik.uni-stuttgart.de>
+
+ * main.c: Only declare linesize once; declare pagesize not at
+ all, since it is never used.
+ (main): Clear newly allocated line before it is used.
