reporting system. - - Before you report a bug, please check the [20]list of well-known bugs - and, if possible in any way, try a current development snapshot. If - you want to report a bug with versions of GCC before 3.1 we strongly - recommend upgrading to the current release first. - - Before reporting that GCC compiles your code incorrectly, please - compile it with gcc -Wall and see whether this shows anything wrong - with your code that could be the cause instead of a bug in GCC. - -Summarized bug reporting instructions - - After this summary, you'll find detailed bug reporting instructions, - that explain how to obtain some of the information requested in this - summary. - - What we need - - Please include in your bug report all of the following items, the - first three of which can be obtained from the output of gcc -v: - * the exact version of GCC; - * the system type; - * the options given when GCC was configured/built; - * the complete command line that triggers the bug; - * the compiler output (error messages, warnings, etc.); and - * the preprocessed file (*.i*) that triggers the bug, generated by - adding -save-temps to the complete compilation command, or, in the - case of a bug report for the GNAT front end, a complete set of - source files (see below). - - What we do not want - - * A source file that #includes header files that are left out of the - bug report (see above) - * That source file and a collection of header files. - * An attached archive (tar, zip, shar, whatever) containing all (or - some :-) of the above. - * A code snippet that won't cause the compiler to produce the exact - output mentioned in the bug report (e.g., a snippet with just a - few lines around the one that apparently triggers the bug, with - some pieces replaced with ellipses or comments for extra - obfuscation :-) - * The location (URL) of the package that failed to build (we won't - download it, anyway, since you've already given us what we need to - duplicate the bug, haven't you? :-) - * An error that occurs only some of the times a certain file is - compiled, such that retrying a sufficient number of times results - in a successful compilation; this is a symptom of a hardware - problem, not of a compiler bug (sorry) - * E-mail messages that complement previous, incomplete bug reports. - Post a new, self-contained, full bug report instead, if possible - as a follow-up to the original bug report - * Assembly files (*.s) produced by the compiler, or any binary - files, such as object files, executables or core files - * Duplicate bug reports, or reports of bugs already fixed in the - development tree, especially those that have already been reported - as fixed last week :-) - * Bugs in the assembler, the linker or the C library. These are - separate projects, with separate mailing lists and different bug - reporting procedures - * Bugs in releases or snapshots of GCC not issued by the GNU - Project. Report them to whoever provided you with the release - * Questions about the correctness or the expected behavior of - certain constructs that are not GCC extensions. Ask them in forums - dedicated to the discussion of the programming language - - Where to post it - - Please submit your bug report directly to the [21]GCC GNATS bug - database. Only if this is not possible, mail all information to - [22]bug-gcc@gnu.org or [23]gcc-bugs@gcc.gnu.org. - - The GCC lists have message size limits (200 kbytes) and bug reports - over those limits will currently be bounced. If your bug is larger - than that, please post it using the [24]GCC GNATS bug database. - -Detailed bug reporting instructions - - Please refer to the [25]next section when reporting bugs in GNAT, the - Ada compiler. - - In general, all the information we need can be obtained by collecting - the command line below, as well as its output and the preprocessed - file it generates. - - gcc -v -save-temps all-your-options source-file - - Typically the preprocessed file (extension .i for C or .ii for C++) - will be large, so please compress the resulting file with one of the - popular compression programs such as bzip2, gzip, zip or compress (in - decreasing order of preference). Use maximum compression (-9) if - available. Please include the compressed preprocessor output in your - bug report, even if the source code is freely available elsewhere; it - makes the job of our volunteer testers much easier. - - The only excuses to not send us the preprocessed sources are (i) if - you've found a bug in the preprocessor, or (ii) if you've reduced the - testcase to a small file that doesn't include any other file. If you - can't post the preprocessed sources because they're proprietary code, - then try to create a small file that triggers the same problem. - - Since we're supposed to be able to re-create the assembly output - (extension .s), you usually should not include it in the bug report, - although you may want to post parts of it to point out assembly code - you consider to be wrong. - - Whether to use MIME attachments or uuencode is up to you. In any case, - make sure the compiler command line, version and error output are in - plain text, so that we don't have to decode the bug report in order to - tell who should take care of it. A meaningful subject indicating - language and platform also helps. - - Please avoid posting an archive (.tar, .shar or .zip); we generally - need just a single file to reproduce the bug (the .i/.ii preprocessed - file), and, by storing it in an archive, you're just making our - volunteers' jobs harder. Only when your bug report requires multiple - source files to be reproduced should you use an archive. In any case, - make sure the compiler version, error message, etc, are included in - the body of your bug report as plain text, even if needlessly - duplicated as part of an archive. - - If you fail to supply enough information for a bug report to be - reproduced, someone will probably ask you to post additional - information (or just ignore your bug report, if they're in a bad day, - so try to get it right on the first posting :-). In this case, please - post the additional information to the bug reporting mailing list, not - just to the person who requested it, unless explicitly told so. If - possible, please include in this follow-up all the information you had - supplied in the incomplete bug report (including the preprocessor - output), so that the new bug report is self-contained. - -Detailed bug reporting instructions for GNAT - - See the [26]previous section for bug reporting instructions for GCC - language implementations other than Ada. - - Bug reports have to contain at least the following information in - order to be useful: - * the exact version of GCC, as shown by "gcc -v"; - * the system type; - * the options when GCC was configured/built; - * the exact command line passed to the gcc program triggering the - bug (not just the flags passed to gnatmake, but gnatmake prints - the parameters it passed to gcc) - * a collection of source files for reproducing the bug, preferably a - minimal set (see below); - * a description of the expected behavior; - * a description of actual behavior. - - If your code depends on additional source files (usually package - specifications), submit the source code for these compilation units in - a single file that is acceptable input to gnatchop, i.e. contains no - non-Ada text. If the compilation terminated normally, you can usually - obtain a list of dependencies using the "gnatls -d main_unit" command, - where main_unit is the file name of the main compilation unit (which - is also passed to gcc). - - If you report a bug which causes the compiler to print a bug box, - include that bug box in your report, and do not forget to send all the - source files listed after the bug box along with your report. - - If you use gnatprep, be sure to send in preprocessed sources (unless - you have to report a bug in gnatprep). - - When you have checked that your report meets these criteria, please - submit it accoding to our [27]generic instructions. (If you use a - mailing list for reporting, please include an "[Ada]" tag in the - subject.) - - Managing Bugs (GNATS and the test-suite) - - This section contains information mostly intended for GCC - contributors. - - If you find a bug, but you are not fixing it (yet): - 1. Create a (minimal) test-case. - 2. Add the test-case to our test-suite, marking it as XFAIL unless - the bug is a regression. - 3. Add a bug report referencing the test-case to GNATS. - - If you fix a bug for which there is already a GNATS entry: - 1. Remove the XFAIL on the test-case. - 2. Close the bug report in GNATS. - - If you find a bug, and you are fixing it right then: - 1. Create a (minimal) test-case. - 2. Add the test-case to our test-suite, marking it as PASS. - 3. Check in your fixes. - _________________________________________________________________ - - Frequently Reported Bugs in GCC - -Fortran - - Fortran bugs are documented in the G77 manual rather than explicitly - listed here. Please see [28]Known Causes of Trouble with GNU Fortran - in the G77 manual. - _________________________________________________________________ - -C - - The following are not bugs in the C compiler, but are reported often - enough to warrant a mention here. - - Cannot initialize a static variable with stdin. - This has nothing to do with GCC, but people ask us about it a - lot. Code like this: - -#include <stdio.h> - -FILE *yyin = stdin; - - will not compile with GNU libc (GNU/Linux libc6), because stdin - is not a constant. This was done deliberately, to make it - easier to maintain binary compatibility when the type FILE - needs to be changed. It is surprising for people used to - traditional Unix C libraries, but it is permitted by the C - standard. - - This construct commonly occurs in code generated by old - versions of lex or yacc. We suggest you try regenerating the - parser with a current version of flex or bison, respectively. - In your own code, the appropriate fix is to move the - initialization to the beginning of main. - - There is a common misconception that the GCC developers are - responsible for GNU libc. These are in fact two entirely - separate projects; please check the [29]GNU libc web pages for - details. - - Cannot use preprocessor directive in macro arguments. - Let me guess... you wrote code that looks something like this: - - memcpy(dest, src, -#ifdef PLATFORM1 - 12 -#else - 24 -#endif - ); - - and you got a whole pile of error messages: - - test.c:11: warning: preprocessing directive not recognized within - macro arg - test.c:11: warning: preprocessing directive not recognized within - macro arg - test.c:11: warning: preprocessing directive not recognized within - macro arg - test.c: In function `foo': - test.c:6: undefined or invalid # directive - test.c:8: undefined or invalid # directive - test.c:9: parse error before `24' - test.c:10: undefined or invalid # directive - test.c:11: parse error before `#' - - Update: As of GCC 3.2 this kind of construct is always accepted - and CPP will probably do what you expect, but see the manual - for detailed semantics. - - However, versions of GCC prior to 3.2 did not allow you to put - #ifdef (or any other directive) inside the arguments of a - macro. Your C library's <string.h> happens to define memcpy as - a macro - this is perfectly legitimate. The code therefore - would not compile. - - This kind of code is not portable. It is "undefined behavior" - according to the C standard; that means different compilers - will do different things with it. It is always possible to - rewrite code which uses conditionals inside macros so that it - doesn't. You could write the above example - -#ifdef PLATFORM1 - memcpy(dest, src, 12); -#else - memcpy(dest, src, 24); -#endif - - This is a bit more typing, but I personally think it's better - style in addition to being more portable. - - In recent versions of glibc, printf is among the functions - which are implemented as macros. - _________________________________________________________________ - -C++ - - This is the list of bugs (and non-bugs) in g++ (aka GNU C++) that are - reported very often, but not yet fixed. While it is certainly better - to fix bugs instead of documenting them, this document might save - people the effort of writing a bug report when the bug is already - well-known. [30]How to report bugs tells you how to report a bug. - - There are many reasons why reported bugs don't get fixed. It might be - difficult to fix, or fixing it might break compatibility. Often, - reports get a low priority when there is a simple work-around. In - particular, bugs caused by invalid C++ code have a simple work-around, - fix the code. Now that there is an agreed ISO/ANSI standard for C++, - the compiler has a definitive document to adhere to. Earlier versions - might have accepted source code that is no longer C++. This means that - code which might have `worked' in a previous version, is now rejected. - You should update your code to be C++. - - You should try to use the latest stable release of the GNU C++ - compiler. - - Common problems updating from G++ 2.95 to G++ 3.0 - - G++ 3.0 conforms much closer to the ISO C++ standard (available at - [31]http://www.ncits.org/cplusplus.htm). - - We have also implemented some of the core and library defect reports - (available at - [32]http://anubis.dkuug.dk/jtc1/sc22/wg21/docs/cwg_defects.html & - [33]http://anubis.dkuug.dk/jtc1/sc22/wg21/docs/lwg-defects.html - respectively). - * The ABI has changed. This means that both class layout and name - mangling is different. You must recompile all c++ libraries (if - you don't you will get link errors). - * The standard library is much more conformant, and uses the std:: - namespace. - * std:: is now a real namespace, not an alias for ::. - * The standard header files for the c library don't end with .h, but - begin with c (i.e. <cstdlib> rather than <stdlib.h>). The .h names - are still available, but are deprecated. - * <strstream> is deprecated, use <sstream> instead. - * streambuf::seekoff & streambuf::seekpos are private, instead use - streambuf::pubseekoff & streambuf::pubseekpos respectively. - * If std::operator << (std::ostream &, long long) doesn't exist, you - need to recompile libstdc++ with --enable-long-long. - - This means you may get lots of errors about things like strcmp not - being found. You've most likely forgotton to tell the compiler to look - in the std:: namespace. There are several ways to do this, - * Say, std::strcmp at the call. This is the most explicit way of - saying what you mean. - * Say, using std::strcmp; somewhere before the call. You will need - to do this for each function or type you wish to use from the - standard library. - * Say, using namespace std; somewhere before the call. This is the - quick-but-dirty fix. This brings the whole of the std:: namespace - into scope. Never do this in a header file, as you will be forcing - users of your header file to do the same. - - ABI bugs - - 3.0 had a new ABI, which affected class layout, function mangling and - calling conventions. We had intended it to be complete, unfortunately - some issues came to light, too late to fix in the 3.0 series. The ABI - should not change in dot releases, so we addressed most issues in GCC - 3.1. - - Covariant return types - We do not implement non-trivial covariant returns. We also - generate incorrect virtual function tables for trivial - covariance. Although trivial covariance will work, it is - incompatible with the ABI. GNATS PR 3706 tracks this problem. - - Non-bugs - - Here are some features that have been reported as bugs, but are not. - - Nested classes can access private types of the containing class. - G++ now implements type access control on member types. Defect - report 45 clarifies that nested classes are members of the - class they are nested in, and so are granted access to private - members of that class. - - Classes in exception specifiers must be complete types. - [15.4]/1 tells you that you cannot have an incomplete type, or - pointer to incomplete (other than cv void *) in an exception - specification. - - G++ emits two copies of constructors and destructors. - In general there are three types of constructors (and - destructors). - - 1. The complete object constructor/destructor. - 2. The base object constructor/destructor. - 3. The allocating destructor/deallocating destructor. - - The first two are different, when virtual base classes are - involved. In some cases we can do better, and this is logged in - GNATS. - - Exceptions don't work in multithreaded applications. - You need to rebuild g++ and libstdc++ with --enable-threads. - Remember, c++ exceptions are not like hardware interrupts. You - cannot throw an exception in one thread and catch it in - another. You cannot throw an exception from a signal handler, - and catch it in the main thread. - - Global destructors are not run in the correct order. - Global destructors should be run in the reverse order of their - constructors completing. In most cases this is the same as the - reverse order of constructors starting, but sometimes it is - different, and that is important. You need to compile and link - your programs with --use-cxa-atexit. We have not turned this - switch on by default, as it requires a cxa aware runtime - library (libc, glibc, or equivalent). - - Problems with floating point computations. - In a number of cases, GCC appears to perform floating point - computations incorrectly. For example, the program - - #include <iostream> - int main() { - double min = 0.0; - double max = 0.5; - double width = 0.01; - std::cout << (int)(((max - min) / width) - 1) << std::endl; - } - - might print 50 on some systems and optimization levels, and 51 - on others. - - The is the result of rounding: The computer cannot represent - all real numbers exactly, so it has to use approximations. When - computing with approximation, the computer needs to round to - the nearest representable number. - - This is not a bug in the compiler, but an inherent limitation - of the float and double types. Please study [34]this paper for - more information. - - Templates, scoping, and digraphs. - If you have a class in global namespace, say named X, and want - to give it as a template argument to some other class, say - std::vector, then this here fails with a parser error: - std::vector<::X>. - - The reason is that the standard mandates that the sequence <: - is treated as if it were the token [, and the parser then - reports a parse error before the character : (by which it means - the second colon). There are several such combinations of - characters, and they are called digraphs. - - The simplest way to avoid this is to write std::vector< ::X>, - i.e. place a space between the opening angle bracket and the - scope operator. - - Missing features - - We know some things are missing from G++. - - The export keyword is not implemented. - Most C++ compilers (G++ included) do not yet implement export, - which is necessary for separate compilation of template - declarations and definitions. Without export, a template - definition must be in scope to be used. The obvious workaround - is simply to place all definitions in the header itself. - Alternatively, the compilation unit containing template - definitions may be included from the header. - - Two stage lookup in templates is not implemented. - [14.6] specifies how names are looked up inside a template. G++ - does not do this correctly, but for most templates this will - not be noticeable. - - Parse errors for "simple" code - - Up to and including GCC 3.0, the compiler will give "parse error" for - seemingly simple code, such as -struct A{ - A(); - A(int); - void func(); -}; - -struct B{ - B(A); - B(A,A); - void func(); -}; - -void foo(){ - B b(A(),A(1)); //Variable b, initialized with two temporaries - B(A(2)).func(); //B temporary, initialized with A temporary -} - - The problem is that GCC starts to parse the declaration of b as a - function b returning B, taking a function returning A as an argument. - When it sees the 1, it is too late. The work-around in these cases is - to add additional parentheses around the expressions that are mistaken - as declarations: - (B(A(2))).func(); - - Sometimes, even that is not enough; to show the compiler that this - should be really an expression, a comma operator with a dummy argument - can be used: - B b((0,A()),A(1)); - - Another example is the parse error for the return statement in -struct A{}; - -struct B{ - A a; - A f1(bool); -}; - -A B::f1(bool b) -{ - if (b) - return (A()); - return a; -} - - The problem is that the compiler interprets A() as a function (taking - no arguments, returning A), and (A()) as a cast - with a missing - expression, hence the parse error. The work-around is to omit the - parentheses: - if (b) - return A(); - - This problem occurs in a number of variants; in throw statements, - people also frequently put the object in parentheses. The exact error - also somewhat varies with the compiler version. The work-arounds - proposed do not change the semantics of the program at all; they make - them perhaps less readable. - - Optimization at -O3 takes a very long time - - At -O3, all functions are candidates for inlining. The heuristic used - has some deficiencies which show up when allowed such freedom. This is - g++ specific, as it has an earlier inliner than gcc. - -References - - 1. http://www.gnu.org/software/gcc/bugs.html - 2. http://gcc.gnu.org/bugs.html#report - 3. http://gcc.gnu.org/bugs.html#need - 4. http://gcc.gnu.org/bugs.html#dontwant - 5. http://gcc.gnu.org/bugs.html#where - 6. http://gcc.gnu.org/bugs.html#detailed - 7. http://gcc.gnu.org/bugs.html#gnat - 8. http://gcc.gnu.org/bugs.html#manage - 9. http://gcc.gnu.org/bugs.html#known - 10. http://gcc.gnu.org/bugs.html#general - 11. http://gcc.gnu.org/bugs.html#fortran - 12. http://gcc.gnu.org/bugs.html#c - 13. http://gcc.gnu.org/bugs.html#cplusplus - 14. http://gcc.gnu.org/bugs.html#updating - 15. http://gcc.gnu.org/bugs.html#nonbugs - 16. http://gcc.gnu.org/bugs.html#missing - 17. http://gcc.gnu.org/bugs.html#parsing - 18. http://gcc.gnu.org/bugs.html#-O3 - 19. http://gcc.gnu.org/gnats.html - 20. http://gcc.gnu.org/bugs.html#known - 21. http://gcc.gnu.org/gnats.html - 22. mailto:bug-gcc@gnu.org - 23. mailto:gcc-bugs@gcc.gnu.org - 24. http://gcc.gnu.org/gnats.html - 25. http://gcc.gnu.org/bugs.html#gnat - 26. http://gcc.gnu.org/bugs.html#detailed - 27. http://gcc.gnu.org/bugs.html#where - 28. http://gcc.gnu.org/onlinedocs/g77/Trouble.html - 29. http://www.gnu.org/software/glibc/ - 30. http://gcc.gnu.org/bugs.html#report - 31. http://www.ncits.org/cplusplus.htm - 32. http://anubis.dkuug.dk/jtc1/sc22/wg21/docs/cwg_defects.html - 33. http://anubis.dkuug.dk/jtc1/sc22/wg21/docs/lwg-defects.html - 34. http://www.validlab.com/goldberg/paper.ps diff --git a/contrib/gcc/FREEBSD-Xlist b/contrib/gcc/FREEBSD-Xlist new file mode 100644 index 0000000..45d283e --- /dev/null +++ b/contrib/gcc/FREEBSD-Xlist @@ -0,0 +1,91 @@ +*.brik +*FAQ +*contrib +*etc +*faq.* +*/include +*/install* +*libchill +*libf2c +*libiberty +*libio +*libobjc +*libstdc++ +*lt* +*missing +*mkinstalldirs +*move-if-change +*symlink-tree +*texinfo +*ylwrap +*gcc/.cvsignore +*gcc/ABOUT*NLS +*gcc/*ChangeLog.* +*gcc/README.ACORN +*gcc/README.ALTOS +*gcc/README.APOLLO +*gcc/README.C4X +*gcc/README.FRESCO +*gcc/README.NS32K +*gcc/README.RS6000 +*gcc/README.X11 +*gcc/README.gnat +*gcc/*.bat +*gcc/*.com +*gcc/*.info* +*gcc/bi-parser.[ch] +*gcc/c-gperf.h +*gcc/c-parse.[chy] +*gcc/cexp.c +*gcc/cpp.aux +*gcc/cpp.cps +*gcc/cpp.fns +*gcc/gcc.aux +*gcc/gcc.cps +*gcc/gcc.hlp +*gcc/texinfo.tex +*gcc/.gdbinit +*gcc/install1.texi +*gcc/intl +*gcc/ch +*gcc/cp/hash.h +*gcc/cp/parse.[ch] +*gcc/config/1750a +*gcc/config/a29k +*gcc/config/arc +*gcc/config/arm +*gcc/config/c4x +*gcc/config/clipper +*gcc/config/convex +*gcc/config/dsp16xx +*gcc/config/elxsi +*gcc/config/fx80 +*gcc/config/gmicro +*gcc/config/h8300 +*gcc/config/i370 +*gcc/config/i860 +*gcc/config/i960 +*gcc/config/m32r +*gcc/config/m68k +*gcc/config/m88k +*gcc/config/mn10200 +*gcc/config/mn10300 +*gcc/config/msdos +*gcc/config/ns32k +*gcc/config/pa +*gcc/config/pdp11 +*gcc/config/pyr +*gcc/config/romp +*gcc/config/rs6000 +*gcc/config/sh +*gcc/config/spur +*gcc/config/tahoe +*gcc/config/v850 +*gcc/config/vax +*gcc/config/we32k +*gcc/config/winnt +*gcc/fixinc +*gcc/java +*gcc/objc/objc-parse.[cy] +*gcc/po +*gcc/testsuite diff --git a/contrib/gcc/FREEBSD-deletelist b/contrib/gcc/FREEBSD-deletelist new file mode 100644 index 0000000..87584ca --- /dev/null +++ b/contrib/gcc/FREEBSD-deletelist @@ -0,0 +1,86 @@ +$FreeBSD$ +CVS +.cvsignore +ABOUT*NLS +ChangeLog.lib +FSFChangeLog.* +README.ACORN +README.ALTOS +README.APOLLO +README.AVR +README.C4X +README.FRESCO +README.NS32K +README.RS6000 +README.X11 +README.gnat +*.bat +*.com +*.info* +bi-parser.[ch] +c-gperf.h +c-parse.[chy] +cexp.c +cpp.aux +cpp.cps +cpp.fns +gcc.aux +gcc.cps +gcc.hlp +texinfo.tex +.gdbinit +install1.texi +intl +ch +cp/cfns.[chy] +cp/hash.h +cp/parse.[ch] +config/1750a +config/a29k +config/arc +config/arm +config/avr +config/c4x +config/clipper +config/convex +config/d30v +config/dsp16xx +config/elxsi +config/fr30 +config/fx80 +config/gmicro +config/h8300 +config/i370 +config/i860 +config/i960 +config/m32r +config/m68k +config/m88k +config/mcore +config/mips +config/mn10200 +config/mn10300 +config/msdos +config/ns32k +config/pa +config/pdp11 +config/pj +config/pyr +config/romp +config/rs6000 +config/sh +config/spur +config/tahoe +config/v850 +config/vax +config/we32k +config/winnt +fixinc +gccbug* +java +mkinstalldirs +objc/objc-parse.[cy] +gthr-win32* +po +testsuite +tradcif.c diff --git a/contrib/gcc/FREEBSD-libiberty b/contrib/gcc/FREEBSD-libiberty new file mode 100644 index 0000000..1b8c249 --- /dev/null +++ b/contrib/gcc/FREEBSD-libiberty @@ -0,0 +1,37 @@ +#!

If a directory named by a -I - option is a standard system include directory, the option is - ignored to ensure that the default search order for system - directories and the special treatment of system header files are - not defeated. - * The C and Objective-C compilers no longer accept the "Naming - Types" extension (typedef foo = bar); it was already unavailable - in C++. Code which uses it will need to be changed to use the - "typeof" extension instead: typedef typeof(bar) foo. (We have - removed this extension without a period of deprecation because it - has caused the compiler to crash since version 3.0 and no one - noticed until very recently. Thus we conclude it is not in - widespread use.) - -New Targets and Target Specific Improvements - - IA-32 - - * Fixed a number of bugs in SSE and MMX intrinsics. - * Fixed common compiler crashes with SSE instruction set enabled - (implied by -march=pentium3, pentium4, athlon-xp) - * __m128 and __m128i is not 128bit aligned when used in structures. - - x86-64 - - * A bug whereby the compiler could generate bad code for bzero has - been fixed. - * ABI fixes (implying ABI incompatibilities with previous version in - some corner cases) - * Fixed prefetch code generation - -Bug Fixes - - See [1]this message for a list of bugs fixed in this release. - - Changes in GCC 3.2 - -Bug Fixes - - See [2]this message for a list of bugs fixed in this release. - -Caveats - - * The C++ compiler does not correctly zero-initialize - pointers-to-data members. You must explicitly initialize them. For - example: - int S::*m(0); - - will work, but depending on default-initialization to zero will - not work. This bug cannot be fixed in GCC 3.2 without inducing - unacceptable risks. It will be fixed in GCC 3.3. - * This GCC release is based on the GCC 3.1 sourcebase, and thus has - all the [3]changes in the GCC 3.1 series. In addition, GCC 3.2 has - a number of C++ ABI fixes which make its C++ compiler generate - binary code which is incompatible with the C++ compilers found in - earlier GCC releases, including GCC 3.1 and GCC 3.1.1. - -New Languages and Language specific improvements - - C++ - - * There are now no known differences between the C++ ABI implemented - in GCC and the multi-vendor standard. We believe that the ABI for - the C++ standard library is now stable and will not change in - future versions of the compiler. However, hard experience has - taught us to be cautious; it is possible that more problems will - be found. It is our intention to make changes to the ABI only if - they are necessary for correct compilation of C++, as opposed to - conformance to the ABI documents. - * For details on how to build an ABI compliant compiler for - GNU/Linux systems, check the [4]common C++ ABI page. - _________________________________________________________________ - - Please send FSF & GNU inquiries & questions to [5]gnu@gnu.org.

Previously the optimization prefetched random - blocks of memory for most targets except for i386. - * The Java compiler now compiles Java programs much faster and also - works with parallel make. - * Nested functions have been fixed for mips*-*-netbsd*. - * Some missing floating point support routines have beed added for - mips*-*-netbsd*. - * This [1]message gives additional information about the bugs fixed - in this release. - -Caveats - - * The -traditional C compiler option has been deprecated and will be - removed in GCC 3.3. (It remains possible to preprocess non-C code - with the traditional preprocessor.) - * The default debugging format for most ELF platforms (including - GNU/Linux and FreeBSD; notable exception is Solaris) has changed - from stabs to DWARF2. This requires GDB 5.1.1 or later. - -General Optimizer Improvements - - * Jan Hubicka, SuSE Labs, together with Richard Henderson, Red Hat, - and Andreas Jaeger, SuSE Labs, has contributed [2]infrastructure - for profile driven optimizations. - Options -fprofile-arcs and -fbranch-probabilities can now be used - to improve speed of the generated code by profiling the actual - program behaviour on typical runs. In the absence of profile info - the compiler attempts to guess the profile statically. - * [3]SPEC2000 and [4]SPEC95 benchmark suites are now used daily to - monitor performance of the generated code. - According to the SPECInt2000 results on an AMD Athlon CPU, the - code generated by GCC 3.1 is 6% faster on the average (8.2% faster - with profile feedback) compared to GCC 3.0. The code produced by - GCC 3.0 is about 2.1% faster compared to 2.95.3. Tests were done - using the -O2 -march=athlon command-line options. - * Alexandre Oliva, of [5]Red Hat, has generalized the tree inlining - infrastructure developed by [6]CodeSourcery, LLC for the C++ front - end, so that it is now used in the C front end too. Inlining - functions as trees exposes them earlier to the compiler, giving it - more opportunities for optimization. - * Support for data prefetching instructions has been added to the - GCC back end and several targets. A new __builtin_prefetch - intrinsic is available to explicitly insert prefetch instructions - and experimental support for loop array prefetching has been added - (see -fprefetch-loop-array documentation). - * Support for emitting debugging information for macros has been - added for DWARF2. It is activated using -g3. - -New Languages and Language specific improvements - - C/C++ - - * A few more [7]ISO C99 features. - * The preprocessor is 10-50% faster than the preprocessor in GCC - 3.0. - * The preprocessor's symbol table has been merged with the symbol - table of the C, C++ and Objective-C front ends. - * The preprocessor consumes less memory than the preprocessor in GCC - 3.0, often significantly so. On normal input files, it typically - consumes less memory than pre-3.0 cccp-based GCC, too. - - C++ - - * -fhonor-std and -fno-honor-std have been removed. -fno-honor-std - was a workaround to allow std compliant code to work with the - non-std compliant libstdc++-v2. libstdc++-v3 is std compliant. - * The C++ ABI has been fixed so that void (A::*)() const is mangled - as "M1AKFvvE", rather than "MK1AFvvE" as before. This change only - affects pointer to cv-qualified member function types. - * The C++ ABI has been changed to correctly handle this code: - struct A { - void operator delete[] (void *, size_t); - }; - - struct B : public A { - }; - - new B[10]; - - The amount of storage allocated for the array will be greater than - it was in 3.0, in order to store the number of elements in the - array, so that the correct size can be passed to operator delete[] - when the array is deleted. Previously, the value passed to - operator delete[] was unpredictable. - This change will only affect code that declares a two-argument - operator delete[] with a second parameter of type size_t in a base - class, and does not override that definition in a derived class. - * The C++ ABI has been changed so that: - struct A { - void operator delete[] (void *, size_t); - void operator delete[] (void *); - }; - - does not cause unnecessary storage to be allocated when an array - of A objects is allocated. - This change will only affect code that declares both of these - forms of operator delete[], and declared the two-argument form - before the one-argument form. - * The C++ ABI has been changed so that when a parameter is passed by - value, any cleanup for that parameter is performed in the caller, - as specified by the ia64 C++ ABI, rather than the called function - as before. As a result, classes with a non-trivial destructor but - a trivial copy constructor will be passed and returned by - invisible reference, rather than by bitwise copy as before. - * G++ now supports the "named return value optimization": for code - like - A f () { - A a; - ... - return a; - } - - G++ will allocate a in the return value slot, so that the return - becomes a no-op. For this to work, all return statements in the - function must return the same variable. - * Improvements to the C++ library are listed in [8]the libstdc++-v3 - FAQ. - - Objective-C - - * Annoying linker warnings (due to incorrect code being generated) - have been fixed. - * If a class method cannot be found, the compiler no longer issues a - warning if a corresponding instance method exists in the root - class. - * Forward @protocol declarations have been fixed. - * Loading of categories has been fixed in certain situations (GNU - run time only). - * The class lookup in the run-time library has been rewritten so - that class method dispatch is more than twice as fast as it used - to be (GNU run time only). - - Java - - * libgcj now includes RMI, java.lang.ref.*, javax.naming, and - javax.transaction. - * Property files and other system resources can be compiled into - executables which use libgcj using the new gcj --resource feature. - * libgcj has been ported to more platforms. In particular there is - now a mostly-functional mingw32 (Windows) target port. - * JNI and CNI invocation interfaces were implemented, so - gcj-compiled Java code can now be called from a C/C++ application. - * gcj can now use builtin functions for certain known methods, for - instance Math.cos. - * gcj can now automatically remove redundant array-store checks in - some common cases. - * The --no-store-checks optimization option was added. This can be - used to omit runtime store checks for code which is known not to - throw ArrayStoreException - * The following third party interface standards were added to - libgcj: org.w3c.dom and org.xml.sax. - * java.security has been merged with GNU Classpath. The new package - is now JDK 1.2 compliant, and much more complete. - * A bytecode verifier was added to the libgcj interpreter. - * java.lang.Character was rewritten to comply with the Unicode 3.0 - standard, and improve performance. - * Partial support for many more locales was added to libgcj. - * Socket timeouts have been implemented. - * libgcj has been merged into a single shared library. There are no - longer separate shared libraries for the garbage collector and - zlib. - * Several performance improvements were made to gcj and libgcj: - + Hash synchronization (thin locks) - + A special allocation path for finalizer-free objects - + Thread-local allocation - + Parallel GC, and other GC tweaks - - Fortran - - Fortran improvements are listed in [9]the Fortran documentation. - - Ada - - [10]Ada Core Technologies, Inc, has contributed its GNAT Ada 95 front - end and associated tools. The GNAT compiler fully implements the Ada - language as defined by the ISO/IEC 8652 standard. - - Please note that the integration of the Ada front end is still work in - progress. - -New Targets and Target Specific Improvements - - * Hans-Peter Nilsson has contributed a port to [11]MMIX, the CPU - architecture used in new editions of Donald E. Knuth's The Art of - Computer Programming. - * [12]Axis Communications has contributed its port to the CRIS CPU - architecture, used in the ETRAX system-on-a-chip series. See - [13]Axis' developer site for technical information. - * Alexandre Oliva, of [14]Red Hat, has contributed a port to the - [15]SuperH SH5 64-bit RISC microprocessor architecture, extending - the existing SH port. - * UltraSPARC is fully supported in 64-bit mode. The option -m64 - enables it. - * For compatibility with the Sun compiler #pragma redefine_extname - has been implemented on Solaris. - * The x86 back end has had some noticeable work done to it. - + [16]SuSE Labs developers Jan Hubicka, Bo Thorsen and Andreas - Jaeger have contributed a port to the AMD x86-64 - architecture. For more information on x86-64 see - [17]http://www.x86-64.org. - + The compiler now supports MMX, 3DNow!, SSE, and SSE2 - instructions. Options -mmmx, -m3dnow, -msse, and -msse2 will - enable the respective instruction sets. Intel C++ compatible - MMX/3DNow!/SSE intrinsics are implemented. SSE2 intrinsics - will be added in next major release. - + Following those improvements, targets for Pentium MMX, K6-2, - K6-3, Pentium III, Pentium 4, and Athlon 4 Mobile/XP/MP were - added. Refer to the documentation on -march= and -mcpu= - options for details. - + For those targets that support it, -mfpmath=sse will cause - the compiler to generate SSE/SSE2 instructions for floating - point math instead of x87 instructions. Usually, this will - lead to quicker code -- especially on the Pentium 4. Note - that only scalar floating point instructions are used and GCC - does not exploit SIMD features yet. - + Prefetch support has been added to the Pentium III, Pentium - 4, K6-2, K6-3, and Athlon series. - + Code generated for floating point to integer converisons has - been improved leading to better performance of many 3D - applications. - * The PowerPC back end has added 64-bit PowerPC GNU/Linux support. - * C++ support for AIX has been improved. - * Aldy Hernandez, of [18]Red Hat, Inc has contributed extensions to - the PowerPC port supporting the AltiVec programming model (SIMD). - The support, though presently useful, is experimental and is - expected to stabilize for 3.2. The support is written to conform - to Motorola's AltiVec specs. See -maltivec. - -Obsolete Systems - - Support for a number of older systems has been declared obsolete in - GCC 3.1. Unless there is activity to revive them, the next release of - GCC will have their sources permanently removed. - - All configurations of the following processor architectures have been - declared obsolete: - * MIL-STD-1750A, 1750a-*-* - * AMD A29k, a29k-*-* - * Convex, c*-convex-* - * Clipper, clipper-*-* - * Elxsi, elxsi-*-* - * Intel i860, i860-*-* - * Sun picoJava, pj-*-* and pjl-*-* - * Western Electric 32000, we32k-*-* - - Most configurations of the following processor architectures have been - declared obsolete, but we are preserving a few systems which may have - active developers.

This allows the compiler to assume the strictest aliasing - rules applicable to the language being compiled. For C and C++, - this activates optimizations based on the type of expressions. - This optimization may thus break old, non-compliant code. - * Enumerations are now properly promoted to int in function - parameters and function returns. Normally this change is not - visible, but when using -fshort-enums this is an ABI change. - * The undocumented extension that allowed C programs to have a label - at the end of a compound statement has been deprecated and may be - removed in a future version. Programs that now generate a warning - about this may be fixed by adding a null statement (a single - semicolon) after the label. - * The poorly documented extension that allowed string constants in - C, C++ and Objective C to contain unescaped newlines has been - deprecated and may be removed in a future version. Programs using - this extension may be fixed in several ways: the bare newline may - be replaced by \n, or preceded by \n\, or string concatenation may - be used with the bare newline preceded by \n" and " placed at the - start of the next line. - * The Chill compiler is not included in GCC 3.0, because of the lack - of a volunteer to convert it to use garbage collection. - * Certain non-standard iostream methods from earlier versions of - libstdc++ are not included in libstdc++ v3, i.e. filebuf::attach, - ostream::form, and istream::gets. Here are workaround hints for: - [1]ostream::form, [2]filebuf::attach. - * The new C++ ABI is not yet fully supported by current (as of - 2001-07-01) releases and development versions of GDB, or any - earlier versions.

This - is particularly noticeable when compiling older versions of the - Linux kernel (2.0.xx). Please refer to the [1]FAQ for more - information on this issue. - * GCC 2.95 implements type based alias analysis to disambiguate - memory references. Some programs, particularly the Linux kernel - violate ANSI/ISO aliasing rules and therefore may not operate - correctly when compiled with GCC 2.95. Please refer to the [2]FAQ - for more information on this issue. - * GCC 2.95 has a known bug in its handling of complex variables for - 64bit targets. Instead of silently generating incorrect code, GCC - 2.95 will issue a fatal error for situations it can not handle. - This primarily affects the Fortran community as Fortran makes more - use of complex variables than C or C++. - * GCC 2.95 has an integrated libstdc++, but does not have an - integrated libg++. Furthermore old libg++ releases will not work - with GCC 2.95. You can retrieve a recent copy of libg++ from the - [3]GCC ftp server. - Note most C++ programs only need libstdc++. - * Exception handling may not work with shared libraries, - particularly on alphas, hppas, rs6000/powerpc and mips based - platforms. Exception handling is known to work on x86 GNU/Linux - platforms with shared libraries. - * In general, GCC 2.95 is more rigorous about rejecting invalid C++ - code or deprecated C++ constructs than G++ 2.7, G++ 2.8, EGCS 1.0, - or EGCS 1.1. As a result it may be necessary to fix C++ code - before it will compile with GCC 2.95. - * G++ is also converting toward the ISO C++ standard; as a result - code which was previously valid (and thus accepted by other - compilers and older versions of g++) may no longer be accepted. - The flag -fpermissive may allow some non-conforming code to - compile with GCC 2.95. - * GCC 2.95 compiled C++ code is not binary compatible with EGCS - 1.1.x, EGCS 1.0.x or GCC 2.8.x. - * GCC 2.95 does not have changes from the GCC 2.8 tree that were - made between Sept 30, 1998 and April 30, 1999 (the official end of - the GCC 2.8 project). Future GCC releases will include all the - changes from the defunct GCC 2.8 sources. - _________________________________________________________________ - - Please send FSF & GNU inquiries & questions to [4]gnu@gnu.org.

Changes since the - EGCS 1.0 release: - * Add support for Red Hat 5.0 Linux and better support for Linux - systems using glibc2. - Many programs failed to link when compiled with EGCS 1.0 on Red - Hat 5.0 or on systems with newer versions of glibc2. EGCS 1.0.1 - should fix these problems. - * Compatibility with both EGCS 1.0 and GCC 2.8 libgcc exception - handling interfaces. - To avoid future compatibility problems, we strongly urge anyone - who is planning on distributing shared libraries that contain C++ - code to upgrade to EGCS 1.0.1 first. - Soon after EGCS 1.0 was released, the GCC developers made some - incompatible changes in libgcc's exception handling interfaces. - These changes were needed to solve problems on some platforms. - This means that GCC 2.8.0, when released, will not be seamlessly - compatible with shared libraries built by EGCS 1.0. The reason is - that the libgcc.a in GCC 2.8.0 will not contain a function needed - by the old interface. - The result of this is that there may be compatibility problems - with shared libraries built by EGCS 1.0 when used with GCC 2.8.0. - With EGCS 1.0.1, generated code uses the new (GCC 2.8.0) - interface, and libgcc.a has the support routines for both the old - and the new interfaces (so EGCS 1.0.1 and EGCS 1.0 code can be - freely mixed, and EGCS 1.0.1 and GCC 2.8.0 code can be freely - mixed). - The maintainers of GCC 2.x have decided against including seamless - support for the old interface in 2.8.0, since it was never - "official", so to avoid future compatibility problems we recommend - against distributing any shared libraries built by EGCS 1.0 that - contain C++ code (upgrade to 1.0.1 and use that). - * Various bugfixes in the x86, hppa, mips, and rs6000/ppc backends. - The x86 changes fix code generation errors exposed when building - glibc2 and the Linux dynamic linker (ld.so). - The hppa change fixes a compiler abort when configured for use - with RTEMS. - The MIPS changes fix problems with the definition of LONG_MAX on - newer systems, allow for command line selection of the target ABI, - and fix one code generation problem. - The rs6000/ppc change fixes some problems with passing structures - to varargs/stdarg functions. - * A few machine independent bugfixes, mostly to fix code generation - errors when building Linux kernels or glibc. - * Fix a few critical exception handling and template bugs in the C++ - compiler. - * Fix Fortran namelist bug on alphas. - * Fix build problems on x86-solaris systems. - - An important goal of EGCS is to allow wide scale testing of new - features and optimizations which are still under development. However, - EGCS has been carefully tested and should be comparable in quality to - most GCC releases. - - EGCS 1.0.1 is based on an August 2, 1997 snapshot of the GCC 2.8 - development sources; it contains nearly all of the new features found - in GCC 2.8. - - EGCS also contains many improvements and features not found in GCC 2.7 - and even the soon to be released GCC 2.8 compilers. - * Integrated C++ runtime libraries, including support for most major - linux systems! - * The integrated libstdc++ library includes a verbatim copy of SGI's - STL release. - * Integrated GNU Fortran compiler - * New instruction scheduler - * New alias analysis code - - See the [1]new features page for a more complete list of new features - found in EGCS 1.0.x releases. - - The EGCS 1.0.1 release includes installation instructions in both HTML - and plaintext forms (see the INSTALL directory in the toplevel - directory of the EGCS 1.0.1 distribution).

In November 1988, it was -judged superior to the AT&T compiler in a Unix World review. In 1990 it -won a Sun Observer ``Best-Of'' award. But now, with new requirements -coming out of the @sc{ansi} C++ committee and a growing backlog of bugs, it's -clear that @sc{gnu} C++ needs an overhaul. - -The C++ language has been under development since 1982. It has -evolved significantly since its original incarnation (C with Classes), -addressing many commercial needs and incorporating many lessons -learned as more and more people started using ``object-oriented'' -programming techniques. In 1989, the first X3J16 committee meeting -was held in Washington DC; in the interest of users, C++ was going to -be standardized. - -As C++ has become more popular, more demands have been placed on its -compilers. Some compilers are up to the demands, others are not. -@sc{gnu} C++ was used to prototype several features which have since -been incorporated into the standard, most notably exception handling. -While @sc{gnu} C++ has been an excellent experimental vehicle, it did -not have the resources that AT&T, Borland, or Microsoft have at their -disposal. - -We believe that @sc{gnu} C++ is an important compiler, providing users with -many of the features that have made @sc{gnu} C so popular: fast compilation, -good error messages, innovative features, and full sources that may be -freely redistributed. The purpose of this overhaul, dubbed the @var{@sc{gnu} -C++ Renovation Project}, is to take advantage of the functionality that -@sc{gnu} C++ offers today, to strengthen its base technology, and put it in a -position to remain---as other @sc{gnu} software currently is---the technical -leader in the field. - -This release represents the latest phase of work in strengthening the -compiler on a variety of points. It includes many months of -work concentrated on fixing many of the more egregious bugs that -presented themselves in the compiler recently. -@ignore -@c FIXME-- update? -Nearly 85% of all bugs reported in the period of February to September -of 1992 were fixed as part of the work in the first phase. -@end ignore -In the coming months, we hope to continue expanding and enhancing the -quality and dependability of the industry's only freely redistributable -C++ compiler. - -@node Changes -@chapter Changes in Behavior in @sc{gnu} C++ - -The @sc{gnu} C++ compiler continues to improve and change. A major goal -of our work has been to continue to bring the compiler into compliance -with the draft @sc{ansi} C++ standard, and with @cite{The Annotated C++ -Reference Manual} (the @sc{arm}).

The work during its most recent phase (1.3) -had these major effects: - -@itemize @bullet -@item The standard compiler driver @code{g++} is now the faster compiled -version, rather than a shell script. - -@item Nested types work much better; notably, nesting is no longer -restricted to nine levels. - -@item Better @sc{arm} conformance on member access control. - -@item The compiler now always generates default assignment operators -(@samp{operator =}), copy constructors (@samp{X::X(X&)}), and default -constructors (@samp{X::X()}) whenever they are required. - -@item The new draft @sc{ansi} standard keyword @code{mutable} is supported. - -@item @samp{-fansi-overloading} is the default, to comply better with -the @sc{arm} (at some cost in compatibility to earlier versions of @sc{gnu} C++). - -@item More informative error messages. - -@item System include files are automatically treated as if they were -wrapped in @samp{extern "C" @{ @}}. - -@item The new option @samp{-falt-external-templates} provides alternate -template instantiation semantics. - -@item Operator declarations are now checked more strictly. - -@item You can now use template type arguments in the template parameter list. - -@item You can call the destructor for any type. - -@item The compiler source code is better organized. - -@item You can specify where to instantiate template definitions explicitly. -@end itemize - -Much of the work in Phase 1.3 went to elimination of known bugs, as well -as the major items above. - -During the span of Phase 1.3, there were also two changes associated -with the compiler that, while not specifically part of the C++ -Renovation project, may be of interest: - -@itemize @bullet -@item @code{gcov}, a code coverage tool for @sc{gnu cc}, is now available -from Cygnus Support. (@code{gcov} is free software, but the @sc{fsf} has not -yet accepted it.) @xref{Gcov,, @code{gcov}: a Test Coverage Program, -gcc.info, Using GNU CC}, for more information (in Cygnus releases of -that manual). - -@item @sc{gnu} C++ now supports @dfn{signatures}, a language extension to -provide more flexibility in abstract type definitions. @xref{C++ -Signatures,, Type Abstraction using Signatures, gcc.info, Using GNU CC}. -@end itemize - -@node Major changes -@section Major Changes - -This release includes four wholesale rewrites of certain areas of -compiler functionality: - -@enumerate 1 -@item Argument matching. @sc{gnu} C++ is more compliant with the rules -described in Chapter 13, ``Overloading'', of the @sc{arm}. This behavior is -the default, though you can specify it explicitly with -@samp{-fansi-overloading}. For compatibility with earlier releases of -@sc{gnu} C++, specify @samp{-fno-ansi-overloading}; this makes the compiler -behave as it used to with respect to argument matching and name overloading. - -@item Default constructors/destructors. Section 12.8 of the @sc{arm}, ``Copying -Class Objects'', and Section 12.1, ``Constructors'', state that a -compiler must declare such default functions if the user does not -specify them. @sc{gnu} C++ now declares, and generates when necessary, -the defaults for constructors and destructors you might omit. In -particular, assignment operators (@samp{operator =}) behave the same way -whether you define them, or whether the compiler generates them by -default; taking the address of the default @samp{operator =} is now -guaranteed to work. Default copy constructors (@samp{X::X(X&)}) now -function correctly, rather than calling the copy assignment operator for -the base class. Finally, constructors (@samp{X::X()}), as well as -assignment operators and copy constructors, are now available whenever -they are required. - -@c XXX This may be taken out eventually... -@item Binary incompatibility. There are no new binary incompatibilities -in Phase 1.3, but Phase 1.2 introduced two binary incompatibilities with -earlier releases. First, the functionality of @samp{operator -new} and @samp{operator delete} changed. Name encoding -(``mangling'') of virtual table names changed as well. Libraries -built with versions of the compiler earlier than Phase 1.2 must be -compiled with the new compiler. (This includes the Cygnus Q2 -progressive release and the FSF 2.4.5 release.) - -@item New @code{g++} driver. -A new binary @code{g++} compiler driver replaces the shell script. -The new driver executes faster. -@end enumerate - -@node New features -@section New features - -@itemize @bullet -@item -The compiler warns when a class contains only private constructors -or destructors, and has no friends. At the request of some of our -customers, we have added a new option, @samp{-Wctor-dtor-privacy} (on by -default), and its negation, @samp{-Wno-ctor-dtor-privacy}, to control -the emission of this warning. If, for example, you are working towards -making your code compile warning-free, you can use @w{@samp{-Wall --Wno-ctor-dtor-privacy}} to find the most common warnings. - -@item -There is now a mechanism which controls exactly when templates are -expanded, so that you can reduce memory usage and program size and also -instantiate them exactly once. You can control this mechanism with the -option @samp{-fexternal-templates} and its corresponding negation -@samp{-fno-external-templates}. Without this feature, space consumed by -template instantiations can grow unacceptably in large-scale projects -with many different source files. The default is -@samp{-fno-external-templates}. - -You do not need to use the @samp{-fexternal-templates} option when -compiling a file that does not define and instantiate templates used in -other files, even if those files @emph{are} compiled with -@samp{-fexternal-templates}. The only side effect is an increase in -object size for each file that was compiled without -@samp{-fexternal-templates}. - -When your code is compiled with @samp{-fexternal-templates}, all -template instantiations are external; this requires that the templates -be under the control of @samp{#pragma interface} and @samp{#pragma -implementation}. All instantiations that will be needed should be in -the implementation file; you can do this with a @code{typedef} that -references the instantiation needed. Conversely, when you compile using -the option @samp{-fno-external-templates}, all template instantiations are -explicitly internal. - -@samp{-fexternal-templates} also allows you to finally separate class -template function definitions from their declarations, thus speeding up -compilation times for every file that includes the template declaration. -Now you can have tens or even hundreds of lines in template -declarations, and thousands or tens of thousands of lines in template -definitions, with the definitions only going through the compiler once -instead of once for each source file. It is important to note that you -must remember to externally instantiate @emph{all} templates that are -used from template declarations in interface files. If you forget to do -this, unresolved externals will occur. - -In the example below, the object file generated (@file{example.o}) will -contain the global instantiation for @samp{Stack<int>}. If other types -of @samp{Stack} are needed, they can be added to @file{example.cc} or -placed in a new file, in the same spirit as @file{example.cc}. - -@code{foo.h}: -@smallexample -@group -#pragma interface "foo.h" -template<class T> -class Stack @{ - static int statc; - static T statc2; - Stack() @{ @} - virtual ~Stack() @{ @} - int bar(); -@}; -@end group -@end smallexample - -@code{example.cc}: -@smallexample -@group -#pragma implementation "foo.h" -#include "foo.h" - -typedef Stack<int> t; -int Stack<int>::statc; -int Stack<int>::statc2; -int Stack<int>::bar() @{ @} -@end group -@end smallexample - -Note that using @samp{-fexternal-templates} does not reduce memory usage -from completely different instantiations (@samp{Stack<Name>} vs. -@samp{Stack<Net_Connection>}), but only collapses different occurrences -of @samp{Stack<Name>} so that only one @samp{Stack<Name>} is generated. - -@samp{-falt-external-templates} selects a slight variation in the -semantics described above (incidentally, you need not specify both -options; @samp{-falt-external-templates} implies -@samp{-fexternal-templates}). - -With @samp{-fexternal-templates}, the compiler emits a definition in the -implementation file that includes the header definition, @emph{even if} -instantiation is triggered from a @emph{different} implementation file -(e.g. with a template that uses another template). - -With @samp{-falt-external-templates}, the definition always goes in the -implementation file that triggers instantiation. - -For instance, with these two header files--- - -@example -@exdent @file{a.h}: -#pragma interface -template <class T> class A @{ @dots{} @}; - -@exdent @file{b.h}: -#pragma interface -class B @{ @dots{} @}; -void f (A<B>); -@end example - -Under @samp{-fexternal-templates}, the definition of @samp{A<B>} ends up -in the implementation file that includes @file{a.h}. Under -@samp{-falt-external-templates}, the same definition ends up in the -implementation file that includes @file{b.h}. - -@item -You can control explicitly where a template is instantiated, without -having to @emph{use} the template to get an instantiation. - -To instantiate a class template explicitly, write @samp{template -class @var{name}<paramvals>}, where @var{paramvals} is a list of values -for the template parameters. For example, you might write - -@example -template class A<int> -@end example - -Similarly, to instantiate a function template explicitly, write -@samp{template @var{fnsign}} where @var{fnsign} is the particular -function signature you need. For example, you might write - -@example -template void foo (int, int) -@end example - -This syntax for explicit template instantiation agrees with recent -extensions to the draft @sc{ansi} standard. - -@item -The compiler's actions on @sc{ansi}-related warnings and errors have -been further enhanced. The @samp{-pedantic-errors} option produces -error messages in a number of new situations: using @code{return} in a -non-@code{void} function (one returning a value); declaring a local -variable that shadows a parameter (e.g., the function takes an argument -@samp{a}, and has a local variable @samp{a}); and use of the @samp{asm} -keyword. Finally, the compiler by default now issues a warning when -converting from an @code{int} to an enumerated type. This is likely to -cause many new warnings in code that hadn't triggered them before. For -example, when you compile this code, - -@smallexample -@group -enum boolean @{ false, true @}; -void -f () -@{ - boolean x; - - x = 1; //@i{assigning an @code{int} to an @code{enum} now triggers a warning} -@} -@end group -@end smallexample - -@noindent -you should see the warning ``@code{anachronistic conversion from integer -type to enumeral type `boolean'}''. Instead of assigning the value 1, -assign the original enumerated value @samp{true}. -@end itemize - -@node Enhancements and bug fixes -@section Enhancements and bug fixes - -@itemize @bullet -@cindex nested types in template parameters -@item -You can now use nested types in a template parameter list, even if the nested -type is defined within the same class that attempts to use the template. -For example, given a template @code{list}, the following now works: - -@smallexample -struct glyph @{ - @dots{} - struct stroke @{ @dots{} @}; - list<stroke> l; - @dots{} -@} -@end smallexample - -@cindex function pointers vs template parameters -@item -Function pointers now work in template parameter lists. For -example, you might want to instantiate a parameterized @code{list} class -in terms of a pointer to a function like this: - -@smallexample -list<int (*)(int, void *)> fnlist; -@end smallexample - -@item -@c FIXME! Really no limit? Jason said "deeper than 9" now OK... -Nested types are now handled correctly. In particular, there is no -longer a limit to how deeply you can nest type definitions. - -@item -@sc{gnu} C++ now conforms to the specifications in Chapter 11 of the -@sc{arm}, ``Member Access Control''. - -@item -The @sc{ansi} C++ committee has introduced a new keyword @code{mutable}. -@sc{gnu} C++ supports it. Use @code{mutable} to specify that some -particular members of a @code{const} class are @emph{not} constant. For -example, you can use this to include a cache in a data structure that -otherwise represents a read-only database. - -@item -Error messages now explicitly specify the declaration, type, or -expression that contains an error. - -@item -To avoid copying and editing all system include files during @sc{gnu} -C++ installation, the compiler now automatically recognizes system -include files as C language definitions, as if they were wrapped in -@samp{extern "C" @{ @dots{} @}}. - -@item -The compiler checks operator declarations more strictly. For example, -you may no longer declare an @samp{operator +} with three arguments. - -@item -You can now use template type arguments in the same template -parameter list where the type argument is specified (as well as in the -template body). For example, you may write - -@example -template <class T, T t> class A @{ @dots{} @}; -@end example - -@item -Destructors are now available for all types, even built-in ones; for -example, you can call @samp{int::~int}. (Destructors for types like -@code{int} do not actually do anything, but their existence provides a -level of generality that permits smooth template expansion in more -cases.) - -@item -Enumerated types declared inside a class are now handled correctly. - -@item -An argument list for a function may not use an initializer list for its default -value. For example, @w{@samp{void foo ( T x = @{ 1, 2 @} )}} is not permitted. - -@item -A significant amount of work went into improving the ability of the -compiler to act accurately on multiple inheritance and virtual -functions.

This includes bugs that are actually in -the `gcc' back end (GBE) or in `libf2c', because those sets of code are -at least somewhat under the control of (and necessarily intertwined -with) `g77', so it isn't worth separating them out. - - For information on bugs in _other_ versions of `g77', see -`gcc/gcc/f/NEWS'. There, lists of bugs fixed in various versions of -`g77' can help determine what bugs existed in prior versions. - - An online, "live" version of this document (derived directly from -the mainline, development version of `g77' within `gcc') is available -via `http://www.gnu.org/software/gcc/onlinedocs/g77/Trouble.html'. -Follow the "Known Bugs" link. - - The following information was last updated on 2002-02-01: - - * `g77' fails to warn about use of a "live" iterative-DO variable as - an implied-DO variable in a `WRITE' or `PRINT' statement (although - it does warn about this in a `READ' statement). - - * Something about `g77''s straightforward handling of label - references and definitions sometimes prevents the GBE from - unrolling loops. Until this is solved, try inserting or removing - `CONTINUE' statements as the terminal statement, using the `END DO' - form instead, and so on. - - * Some confusion in diagnostics concerning failing `INCLUDE' - statements from within `INCLUDE''d or `#include''d files. - - * `g77' assumes that `INTEGER(KIND=1)' constants range from `-2**31' - to `2**31-1' (the range for two's-complement 32-bit values), - instead of determining their range from the actual range of the - type for the configuration (and, someday, for the constant). - - Further, it generally doesn't implement the handling of constants - very well in that it makes assumptions about the configuration - that it no longer makes regarding variables (types). - - Included with this item is the fact that `g77' doesn't recognize - that, on IEEE-754/854-compliant systems, `0./0.' should produce a - NaN and no warning instead of the value `0.' and a warning. - - * `g77' uses way too much memory and CPU time to process large - aggregate areas having any initialized elements. - - For example, `REAL A(1000000)' followed by `DATA A(1)/1/' takes up - way too much time and space, including the size of the generated - assembler file. - - Version 0.5.18 improves cases like this--specifically, cases of - _sparse_ initialization that leave large, contiguous areas - uninitialized--significantly. However, even with the - improvements, these cases still require too much memory and CPU - time. - - (Version 0.5.18 also improves cases where the initial values are - zero to a much greater degree, so if the above example ends with - `DATA A(1)/0/', the compile-time performance will be about as good - as it will ever get, aside from unrelated improvements to the - compiler.) - - Note that `g77' does display a warning message to notify the user - before the compiler appears to hang. - - * When debugging, after starting up the debugger but before being - able to see the source code for the main program unit, the user - must currently set a breakpoint at `MAIN__' (or `MAIN___' or - `MAIN_' if `MAIN__' doesn't exist) and run the program until it - hits the breakpoint. At that point, the main program unit is - activated and about to execute its first executable statement, but - that's the state in which the debugger should start up, as is the - case for languages like C. - - * Debugging `g77'-compiled code using debuggers other than `gdb' is - likely not to work. - - Getting `g77' and `gdb' to work together is a known - problem--getting `g77' to work properly with other debuggers, for - which source code often is unavailable to `g77' developers, seems - like a much larger, unknown problem, and is a lower priority than - making `g77' and `gdb' work together properly. - - On the other hand, information about problems other debuggers have - with `g77' output might make it easier to properly fix `g77', and - perhaps even improve `gdb', so it is definitely welcome. Such - information might even lead to all relevant products working - together properly sooner. - - * `g77' doesn't work perfectly on 64-bit configurations such as the - Digital Semiconductor ("DEC") Alpha. - - This problem is largely resolved as of version 0.5.23. - - * `g77' currently inserts needless padding for things like `COMMON - A,IPAD' where `A' is `CHARACTER*1' and `IPAD' is `INTEGER(KIND=1)' - on machines like x86, because the back end insists that `IPAD' be - aligned to a 4-byte boundary, but the processor has no such - requirement (though it is usually good for performance). - - The `gcc' back end needs to provide a wider array of - specifications of alignment requirements and preferences for - targets, and front ends like `g77' should take advantage of this - when it becomes available. - - * The `libf2c' routines that perform some run-time arithmetic on - `COMPLEX' operands were modified circa version 0.5.20 of `g77' to - work properly even in the presence of aliased operands. - - While the `g77' and `netlib' versions of `libf2c' differ on how - this is accomplished, the main differences are that we believe the - `g77' version works properly even in the presence of _partially_ - aliased operands. - - However, these modifications have reduced performance on targets - such as x86, due to the extra copies of operands involved. - diff --git a/contrib/gcc/f/NEWS b/contrib/gcc/f/NEWS deleted file mode 100644 index cc73668..0000000 --- a/contrib/gcc/f/NEWS +++ /dev/null @@ -1,531 +0,0 @@ -_Note:_ This file is automatically generated from the files -`news0.texi' and `news.texi'. `NEWS' is _not_ a source file, although -it is normally included within source distributions. - - This file lists news about the GCC-3.2 version (and some other -versions) of the GNU Fortran compiler.

However, bit-sizes never play a - role after offsets have been converted to byte addresses. - Therefore this check has been removed, and the limit is now 2 - Gbyte of memory (around 530 000 000 REALs). Note: On GNU/Linux - systems one has to compile programs that occupy more than 1 Gbyte - statically, i.e. `g77 -static ...'. - - * Based on work done by Juergen Pfeifer (<juergen.pfeifer@gmx.net>) - libf2c is now a shared library. One can still link in all objects - with the program by specifying the `-static' option. - - * Robert Anderson (<rwa@alumni.princeton.edu>) thought up a two line - change that enables g77 to compile such code as: - SUBROUTINE SUB(A, N) - DIMENSION N(2) - DIMENSION A(N(1),N(2)) - A(1,1) = 1. - END - Note the use of array elements in the bounds of the adjustable - array A. - - * George Helffrich (<george@geo.titech.ac.jp>) implemented a change - in substring index checking (when specifying `-fbounds-check') - that permits the use of zero length substrings of the form - `string(1:0)'. - - * Based on code developed by Pedro Vazquez - (<vazquez@penelope.iqm.unicamp.br>), the `libf2c' library is now - able to read and write files larger than 2 Gbyte on 32-bit target - machines, if the operating system supports this. - -In 0.5.26, `GCC' 3.0 versus `GCC' 2.95: -======================================= - - * When a REWIND was issued after a WRITE statement on an unformatted - file, the implicit truncation was performed by copying the - truncated file to /tmp and copying the result back. This has been - fixed by using the `ftruncate' OS function. Thanks go to the - GAMESS developers for bringing this to our attention. - - * Using options `-g', `-ggdb' or `-gdwarf[-2]' (where appropriate - for your target) now also enables debugging information for COMMON - BLOCK and EQUIVALENCE items to be emitted. Thanks go to Andrew - Vaught (<andy@xena.eas.asu.edu>) and George Helffrich - (<george@geology.bristol.ac.uk>) for fixing this longstanding - problem. - - * It is not necessary anymore to use the option `-femulate-complex' - to compile Fortran code using COMPLEX arithmetic, even on 64-bit - machines (like the Alpha). This will improve code generation. - - * INTRINSIC arithmetic functions are now treated as routines that do - not depend on anything but their argument(s). This enables - further instruction scheduling, because it is known that they - cannot read or modify arbitrary locations. - - * Upgrade to `libf2c' as of 2000-12-05. - - This fixes a bug where a namelist containing initialization of - LOGICAL items and a variable starting with T or F would be read - incorrectly. - - * The `TtyNam' intrinsics now set NAME to all spaces (at run time) - if the system has no `ttyname' implementation available. - - * Upgrade to `libf2c' as of 1999-06-28. - - This fixes a bug whereby input to a `NAMELIST' read involving a - repeat count, such as `K(5)=10*3', was not properly handled by - `libf2c'. The first item was written to `K(5)', but the remaining - nine were written elsewhere (still within the array), not - necessarily starting at `K(6)'. - -In 0.5.25, `GCC' 2.95 (`EGCS' 1.2) versus `EGCS' 1.1.2: -======================================================= - - * `g77' no longer generates bad code for assignments, or other - conversions, of `REAL' or `COMPLEX' constant expressions to type - `INTEGER(KIND=2)' (often referred to as `INTEGER*8'). - - For example, `INTEGER*8 J; J = 4E10' now works as documented. - - * `g77' no longer truncates `INTEGER(KIND=2)' (usually `INTEGER*8') - subscript expressions when evaluating array references on systems - with pointers widers than `INTEGER(KIND=1)' (such as Alphas). - - * `g77' no longer generates bad code for an assignment to a - `COMPLEX' variable or array that partially overlaps one or more of - the sources of the same assignment (a very rare construction). It - now assigns through a temporary, in cases where such partial - overlap is deemed possible. - - * `libg2c' (`libf2c') no longer loses track of the file being worked - on during a `BACKSPACE' operation. - - * `libg2c' (`libf2c') fixes a bug whereby input to a `NAMELIST' read - involving a repeat count, such as `K(5)=10*3', was not properly - handled by `libf2c'. The first item was written to `K(5)', but - the remaining nine were written elsewhere (still within the array), - not necessarily starting at `K(6)'. - - * Automatic arrays now seem to be working on HP-UX systems. - - * The `Date' intrinsic now returns the correct result on big-endian - systems. - - * Fix `g77' so it no longer crashes when compiling I/O statements - using keywords that define `INTEGER' values, such as `IOSTAT=J', - where J is other than default `INTEGER' (such as `INTEGER*2'). - Instead, it issues a diagnostic. - - * Fix `g77' so it properly handles `DATA A/RPT*VAL/', where RPT is - not default `INTEGER', such as `INTEGER*2', instead of producing a - spurious diagnostic. Also fix `DATA (A(I),I=1,N)', where `N' is - not default `INTEGER' to work instead of crashing `g77'. - - * The `-ax' option is now obeyed when compiling Fortran programs. - (It is passed to the `f771' driver.) - - * The new `-fbounds-check' option causes `g77' to compile run-time - bounds checks of array subscripts, as well as of substring start - and end points. - - * `libg2c' now supports building as multilibbed library, which - provides better support for systems that require options such as - `-mieee' to work properly. - - * Source file names with the suffixes `.FOR' and `.FPP' now are - recognized by `g77' as if they ended in `.for' and `.fpp', - respectively. - - * The order of arguments to the _subroutine_ forms of the `CTime', - `DTime', `ETime', and `TtyNam' intrinsics has been swapped. The - argument serving as the returned value for the corresponding - function forms now is the _second_ argument, making these - consistent with the other subroutine forms of `libU77' intrinsics. - - * `g77' now warns about a reference to an intrinsic that has an - interface that is not Year 2000 (Y2K) compliant. Also, `libg2c' - has been changed to increase the likelihood of catching references - to the implementations of these intrinsics using the `EXTERNAL' - mechanism (which would avoid the new warnings). - - * `g77' now warns about a reference to a function when the - corresponding _subsequent_ function program unit disagrees with - the reference concerning the type of the function. - - * `-fno-emulate-complex' is now the default option. This should - result in improved performance of code that uses the `COMPLEX' - data type. - - * The `-malign-double' option now reliably aligns _all_ - double-precision variables and arrays on Intel x86 targets. - - * Even without the `-malign-double' option, `g77' reliably aligns - local double-precision variables that are not in `EQUIVALENCE' - areas and not `SAVE''d. - - * `g77' now open-codes ("inlines") division of `COMPLEX' operands - instead of generating a run-time call to the `libf2c' routines - `c_div' or `z_div', unless the `-Os' option is specified. - - * `g77' no longer generates code to maintain `errno', a C-language - concept, when performing operations such as the `SqRt' intrinsic. - - * `g77' developers can temporarily use the `-fflatten-arrays' option - to compare how the compiler handles code generation using C-like - constructs as compared to the Fortran-like method constructs - normally used. - - * A substantial portion of the `g77' front end's code-generation - component was rewritten. It now generates code using facilities - more robustly supported by the `gcc' back end. One effect of this - rewrite is that some codes no longer produce a spurious "label LAB - used before containing binding contour" message. - - * Support for the `-fugly' option has been removed. - - * Improve documentation and indexing, including information on Year - 2000 (Y2K) compliance, and providing more information on internals - of the front end. - - * Upgrade to `libf2c' as of 1999-05-10. - -In 0.5.24 versus 0.5.23: -======================== - - There is no `g77' version 0.5.24 at this time, or planned. 0.5.24 -is the version number designated for bug fixes and, perhaps, some new -features added, to 0.5.23. Version 0.5.23 requires `gcc' 2.8.1, as -0.5.24 was planned to require. - - Due to `EGCS' becoming `GCC' (which is now an acronym for "GNU -Compiler Collection"), and `EGCS' 1.2 becoming officially designated -`GCC' 2.95, there seems to be no need for an actual 0.5.24 release. - - To reduce the confusion already resulting from use of 0.5.24 to -designate `g77' versions within `EGCS' versions 1.0 and 1.1, as well as -in versions of `g77' documentation and notices during that period, -"mainline" `g77' version numbering resumes at 0.5.25 with `GCC' 2.95 -(`EGCS' 1.2), skipping over 0.5.24 as a placeholder version number. - - To repeat, there is no `g77' 0.5.24, but there is now a 0.5.25. -Please remain calm and return to your keypunch units. - -In `EGCS' 1.1.2 versus `EGCS' 1.1.1: -==================================== - - * Fix the `IDate' intrinsic (VXT) (in `libg2c') so the returned year - is in the documented, non-Y2K-compliant range of 0-99, instead of - being returned as 100 in the year 2000. - - * Fix the `Date_and_Time' intrinsic (in `libg2c') to return the - milliseconds value properly in VALUES(8). - - * Fix the `LStat' intrinsic (in `libg2c') to return device-ID - information properly in SARRAY(7). - - * Improve documentation. - -In `EGCS' 1.1.1 versus `EGCS' 1.1: -================================== - - * Fix `libg2c' so it performs an implicit `ENDFILE' operation (as - appropriate) whenever a `REWIND' is done. - - (This bug was introduced in 0.5.23 and `egcs' 1.1 in `g77''s - version of `libf2c'.) - - * Fix `libg2c' so it no longer crashes with a spurious diagnostic - upon doing any I/O following a direct formatted write. - - (This bug was introduced in 0.5.23 and `egcs' 1.1 in `g77''s - version of `libf2c'.) - - * Fix `g77' so it no longer crashes compiling references to the - `Rand' intrinsic on some systems. - - * Fix `g77' portion of installation process so it works better on - some systems (those with shells requiring `else true' clauses on - `if' constructs for the completion code to be set properly). - -In `EGCS' 1.1 versus `EGCS' 1.0.3: -================================== - - * Fix bugs in the `libU77' intrinsic `HostNm' that wrote one byte - beyond the end of its `CHARACTER' argument, and in the `libU77' - intrinsics `GMTime' and `LTime' that overwrote their arguments. - - * Assumed arrays with negative bounds (such as `REAL A(-1:*)') no - longer elicit spurious diagnostics from `g77', even on systems - with pointers having different sizes than integers. - - This bug is not known to have existed in any recent version of - `gcc'. It was introduced in an early release of `egcs'. - - * Valid combinations of `EXTERNAL', passing that external as a dummy - argument without explicitly giving it a type, and, in a subsequent - program unit, referencing that external as an external function - with a different type no longer crash `g77'. - - * `CASE DEFAULT' no longer crashes `g77'. - - * The `-Wunused' option no longer issues a spurious warning about - the "master" procedure generated by `g77' for procedures - containing `ENTRY' statements. - - * Support `FORMAT(I<EXPR>)' when EXPR is a compile-time constant - `INTEGER' expression. - - * Fix `g77' `-g' option so procedures that use `ENTRY' can be - stepped through, line by line, in `gdb'. - - * Allow any `REAL' argument to intrinsics `Second' and `CPU_Time'. - - * Use `tempnam', if available, to open scratch files (as in - `OPEN(STATUS='SCRATCH')') so that the `TMPDIR' environment - variable, if present, is used. - - * `g77''s version of `libf2c' separates out the setting of global - state (such as command-line arguments and signal handling) from - `main.o' into distinct, new library archive members. - - This should make it easier to write portable applications that - have their own (non-Fortran) `main()' routine properly set up the - `libf2c' environment, even when `libf2c' (now `libg2c') is a - shared library. - - * `g77' no longer installs the `f77' command and `f77.1' man page in - the `/usr' or `/usr/local' hierarchy, even if the `f77-install-ok' - file exists in the source or build directory. See the - installation documentation for more information. - - * `g77' no longer installs the `libf2c.a' library and `f2c.h' - include file in the `/usr' or `/usr/local' hierarchy, even if the - `f2c-install-ok' or `f2c-exists-ok' files exist in the source or - build directory. See the installation documentation for more - information. - - * The `libf2c.a' library produced by `g77' has been renamed to - `libg2c.a'. It is installed only in the `gcc' "private" directory - hierarchy, `gcc-lib'. This allows system administrators and users - to choose which version of the `libf2c' library from `netlib' they - wish to use on a case-by-case basis. See the installation - documentation for more information. - - * The `f2c.h' include (header) file produced by `g77' has been - renamed to `g2c.h'. It is installed only in the `gcc' "private" - directory hierarchy, `gcc-lib'. This allows system administrators - and users to choose which version of the include file from - `netlib' they wish to use on a case-by-case basis. See the - installation documentation for more information. - - * The `g77' command now expects the run-time library to be named - `libg2c.a' instead of `libf2c.a', to ensure that a version other - than the one built and installed as part of the same `g77' version - is picked up. - - * During the configuration and build process, `g77' creates - subdirectories it needs only as it needs them. Other cleaning up - of the configuration and build process has been performed as well. - - * `install-info' now used to update the directory of Info - documentation to contain an entry for `g77' (during installation). - - * Some diagnostics have been changed from warnings to errors, to - prevent inadvertent use of the resulting, probably buggy, programs. - These mostly include diagnostics about use of unsupported features - in the `OPEN', `INQUIRE', `READ', and `WRITE' statements, and - about truncations of various sorts of constants. - - * Improve compilation of `FORMAT' expressions so that a null byte is - appended to the last operand if it is a constant. This provides a - cleaner run-time diagnostic as provided by `libf2c' for statements - like `PRINT '(I1', 42'. - - * Improve documentation and indexing. - - * The upgrade to `libf2c' as of 1998-06-18 should fix a variety of - problems, including those involving some uses of the `T' format - specifier, and perhaps some build (porting) problems as well. - -In `EGCS' 1.1 versus `g77' 0.5.23: -================================== - - * Fix a code-generation bug that afflicted Intel x86 targets when - `-O2' was specified compiling, for example, an old version of the - `DNRM2' routine. - - The x87 coprocessor stack was being mismanaged in cases involving - assigned `GOTO' and `ASSIGN'. - - * `g77' no longer produces incorrect code and initial values for - `EQUIVALENCE' and `COMMON' aggregates that, due to "unnatural" - ordering of members vis-a-vis their types, require initial padding. - - * Fix `g77' crash compiling code containing the construct - `CMPLX(0.)' or similar. - - * `g77' no longer crashes when compiling code containing - specification statements such as `INTEGER(KIND=7) PTR'. - - * `g77' no longer crashes when compiling code such as `J = SIGNAL(1, - 2)'. - - * `g77' now treats `%LOC(EXPR)' and `LOC(EXPR)' as "ordinary" - expressions when they are used as arguments in procedure calls. - This change applies only to global (filewide) analysis, making it - consistent with how `g77' actually generates code for these cases. - - Previously, `g77' treated these expressions as denoting special - "pointer" arguments for the purposes of filewide analysis. - - * Fix `g77' crash (or apparently infinite run-time) when compiling - certain complicated expressions involving `COMPLEX' arithmetic - (especially multiplication). - - * Align static double-precision variables and arrays on Intel x86 - targets regardless of whether `-malign-double' is specified. - - Generally, this affects only local variables and arrays having the - `SAVE' attribute or given initial values via `DATA'. - - * The `g77' driver now ensures that `-lg2c' is specified in the link - phase prior to any occurrence of `-lm'. This prevents - accidentally linking to a routine in the SunOS4 `-lm' library when - the generated code wants to link to the one in `libf2c' (`libg2c'). - - * `g77' emits more debugging information when `-g' is used. - - This new information allows, for example, `which __g77_length_a' - to be used in `gdb' to determine the type of the phantom length - argument supplied with `CHARACTER' variables. - - This information pertains to internally-generated type, variable, - and other information, not to the longstanding deficiencies - vis-a-vis `COMMON' and `EQUIVALENCE'. - - * The F90 `Date_and_Time' intrinsic now is supported. - - * The F90 `System_Clock' intrinsic allows the optional arguments - (except for the `Count' argument) to be omitted. - - * Upgrade to `libf2c' as of 1998-06-18. - - * Improve documentation and indexing. - -In previous versions: -===================== - - Information on previous versions is not provided in this -`gcc/gcc/f/NEWS' file, to keep it short. See `gcc/gcc/f/news.texi', or -any of its other derivations (Info, HTML, dvi forms) for such -information. - diff --git a/contrib/gcc/f/g77spec.c b/contrib/gcc/f/g77spec.c index 9206ef7..81725e3 100644 --- a/contrib/gcc/f/g77spec.c +++ b/contrib/gcc/f/g77spec.c @@ -1,6 +1,5 @@ /* Specific flags and argument handling of the Fortran front-end. - Copyright (C) 1997, 1999, 2000, 2001, 2002, 2003 - Free Software Foundation, Inc. + Copyright (C) 1997, 1999, 2000, 2001, 2002 Free Software Foundation, Inc.
