[35]Will GCC someday include an incremental linker? - _________________________________________________________________ - - General information - -What is the relationship between GCC and EGCS? - - In 1990/1991 gcc version 1 had reached a point of stability. For the - targets it could support, it worked well. It had limitations inherent - in its design that would be difficult to resolve, so a major effort - was made to resolve those limitiations and gcc version 2 was the - result. - - When we had gcc2 in a useful state, development efforts on gcc1 - stopped and we all concentrated on making gcc2 better than gcc1 could - ever be. This is the kind of step forward we wanted to make with the - EGCS project when it was formed in 1997. - - In April 1999 the Free Software Foundation officially halted - development on the gcc2 compiler and appointed the EGCS project as the - official GCC maintainers. The net result was a single project which - carries forward GCC development under the ultimate control of the - [36]GCC Steering Committee. - _________________________________________________________________ - -What is the relationship between GCC and Cygnus / Red Hat? - - It is a common mis-conception that Red Hat controls GCC either - directly or indirectly. - - While Red Hat does donate hardware, network connections, code and - developer time to GCC development, Red Hat does not control GCC. - - Overall control of GCC is in the hands of the [37]GCC Steering - Committee which includes people from a variety of different - organizations and backgrounds. The purpose of the steering committee - is to make decisions in the best interest of GCC and to help ensure - that no individual or company has control over the project. - - To summarize, Red Hat contributes to the GCC project, but does not - exert a controlling influence over GCC. - _________________________________________________________________ - -What is an open development model? - - We are using a bazaar style [38][1] approach to GCC development: we - make snapshots publicly available to anyone who wants to try them; we - welcome anyone to join the development mailing list. All of the - discussions on the development mailing list are available via the web. - We're going to be making releases with a much higher frequency than - they have been made in the past. - - In addition to weekly snapshots of the GCC development sources, we - have the sources readable from a CVS server by anyone. Furthermore we - are using remote CVS to allow remote maintainers write access to the - sources. - - There have been many potential GCC developers who were not able to - participate in GCC development in the past. We want these people to - help in any way they can; we ultimately want GCC to be the best - compiler in the world. - - A compiler is a complicated piece of software, there will still be - strong central maintainers who will reject patches, who will demand - documentation of implementations, and who will keep the level of - quality as high as it is today. Code that could use wider testing may - be integrated--code that is simply ill-conceived won't be. - - GCC is not the first piece of software to use this open development - process; FreeBSD, the Emacs lisp repository, and the Linux kernel are - a few examples of the bazaar style of development. - - With GCC, we are adding new features and optimizations at a rate that - has not been done since the creation of gcc2; these additions - inevitably have a temporarily destabilizing effect. With the help of - developers working together with this bazaar style development, the - resulting stability and quality levels will be better than we've had - before. - - [1] We've been discussing different development models a lot over - the past few months. The paper which started all of this introduced - two terms: A cathedral development model versus a bazaar - development model. The paper is written by Eric S. Raymond, it is - called ``[39]The Cathedral and the Bazaar''. The paper is a useful - starting point for discussions. - _________________________________________________________________ - -How do I report a bug? - - There are complete instructions [40]here. - _________________________________________________________________ - -How do I get a bug fixed or a feature added? - - There are lots of ways to get something fixed. The list below may be - incomplete, but it covers many of the common cases. These are listed - roughly in order of increasing difficulty for the average GCC user, - meaning someone who is not skilled in the internals of GCC, and where - difficulty is measured in terms of the time required to fix the bug. - No alternative is better than any other; each has its benefits and - disadvantages. - * Hire someone to fix it for you. There are various companies and - individuals providing support for GCC. This alternative costs - money, but is relatively likely to get results. - * [41]Report the problem to the GCC GNATS bug tracking system and - hope that someone will be kind enough to fix it for you. While - this is certainly possible, and often happens, there is no - guarantee that it will. You should not expect the same response - from this method that you would see from a commercial support - organization since the people who read GCC bug reports, if they - choose to help you, will be volunteering their time. This - alternative will work best if you follow the directions on - [42]submitting bugreports. - * Fix it yourself. This alternative will probably bring results, if - you work hard enough, but will probably take a lot of time, and, - depending on the quality of your work and the perceived benefits - of your changes, your code may or may not ever make it into an - official release of GCC. - _________________________________________________________________ - -Does GCC work on my platform? - - The host/target specific installation notes for GCC include - information about known problems with installing or using GCC on - particular platforms. These are included in the sources for a release - in INSTALL/specific.html, and the [43]latest version is always - available at the GCC web site. Reports of [44]successful builds for - several versions of GCC are also available at the web site. - _________________________________________________________________ - - Installation - -How to install multiple versions of GCC - - It may be desirable to install multiple versions of the compiler on - the same system. This can be done by using different prefix paths at - configure time and a few symlinks. - - Basically, configure the two compilers with different --prefix - options, then build and install each compiler. Assume you want "gcc" - to be the latest compiler and available in /usr/local/bin; also assume - that you want "gcc2" to be the older gcc2 compiler and also available - in /usr/local/bin. - - The easiest way to do this is to configure the new GCC with - --prefix=/usr/local/gcc and the older gcc2 with - --prefix=/usr/local/gcc2. Build and install both compilers. Then make - a symlink from /usr/local/bin/gcc to /usr/local/gcc/bin/gcc and from - /usr/local/bin/gcc2 to /usr/local/gcc2/bin/gcc. Create similar links - for the "g++", "c++" and "g77" compiler drivers. - - An alternative to using symlinks is to configure with a - --program-transform-name option. This option specifies a sed command - to process installed program names with. Using it you can, for - instance, have all the new GCC programs installed as "new-gcc" and the - like. You will still have to specify different --prefix options for - new GCC and old GCC, because it is only the executable program names - that are transformed. The difference is that you (as administrator) do - not have to set up symlinks, but must specify additional directories - in your (as a user) PATH. A complication with --program-transform-name - is that the sed command invariably contains characters significant to - the shell, and these have to be escaped correctly, also it is not - possible to use "^" or "$" in the command. Here is the option to - prefix "new-" to the new GCC installed programs: - - --program-transform-name='s,\\\\(.*\\\\),new-\\\\1,' - - With the above --prefix option, that will install the new GCC programs - into /usr/local/gcc/bin with names prefixed by "new-". You can use - --program-transform-name if you have multiple versions of GCC, and - wish to be sure about which version you are invoking. - - If you use --prefix, GCC may have difficulty locating a GNU assembler - or linker on your system, [45]GCC can not find GNU as/GNU ld explains - how to deal with this. - - Another option that may be easier is to use the --program-prefix= or - --program-suffix= options to configure. So if you're installing GCC - 2.95.2 and don't want to disturb the current version of GCC in - /usr/local/bin/, you could do - - configure --program-suffix=-2.95.2 - - This should result in GCC being installed as /usr/local/bin/gcc-2.95.2 - instead of /usr/local/bin/gcc. - _________________________________________________________________ - -Dynamic linker is unable to find GCC libraries - - This problem manifests itself by programs not finding shared libraries - they depend on when the programs are started. Note this problem often - manifests itself with failures in the libio/libstdc++ tests after - configuring with --enable-shared and building GCC. - - GCC does not specify a runpath so that the dynamic linker can find - dynamic libraries at runtime. - - The short explanation is that if you always pass a -R option to the - linker, then your programs become dependent on directories which may - be NFS mounted, and programs may hang unnecessarily when an NFS server - goes down. - - The problem is not programs that do require the directories; those - programs are going to hang no matter what you do. The problem is - programs that do not require the directories. - - SunOS effectively always passed a -R option for every -L option; this - was a bad idea, and so it was removed for Solaris. We should not - recreate it. - - However, if you feel you really need such an option to be passed - automatically to the linker, you may add it to the GCC specs file. - This file can be found in the same directory that contains cc1 (run - gcc -print-prog-name=cc1 to find it). You may add linker flags such as - -R or -rpath, depending on platform and linker, to the *link or *lib - specs. - - Another alternative is to install a wrapper script around gcc, g++ or - ld that adds the appropriate directory to the environment variable - LD_RUN_PATH or equivalent (again, it's platform-dependent). - - Yet another option, that works on a few platforms, is to hard-code the - full pathname of the library into its soname. This can only be - accomplished by modifying the appropriate .ml file within - libstdc++/config (and also libg++/config, if you are building libg++), - so that $(libdir)/ appears just before the library name in -soname or - -h options. - _________________________________________________________________ - -GCC can not find GNU as/GNU ld - - GCC searches the PATH for an assembler and a loader, but it only does - so after searching a directory list hard-coded in the GCC executables. - Since, on most platforms, the hard-coded list includes directories in - which the system asembler and loader can be found, you may have to - take one of the following actions to arrange that GCC uses the GNU - versions of those programs. - - To ensure that GCC finds the GNU assembler (the GNU loader), which are - required by [46]some configurations, you should configure these with - the same --prefix option as you used for GCC. Then build & install GNU - as (GNU ld) and proceed with building GCC. - - Another alternative is to create links to GNU as and ld in any of the - directories printed by the command `gcc -print-search-dirs | grep - '^programs:''. The link to `ld' should be named `real-ld' if `ld' - already exists. If such links do not exist while you're compiling GCC, - you may have to create them in the build directories too, within the - gcc directory and in all the gcc/stage* subdirectories. - - GCC 2.95 allows you to specify the full pathname of the assembler and - the linker to use. The configure flags are `--with-as=/path/to/as' and - `--with-ld=/path/to/ld'. GCC will try to use these pathnames before - looking for `as' or `(real-)ld' in the standard search dirs. If, at - configure-time, the specified programs are found to be GNU utilities, - `--with-gnu-as' and `--with-gnu-ld' need not be used; these flags will - be auto-detected. One drawback of this option is that it won't allow - you to override the search path for assembler and linker with - command-line options -B/path/ if the specified filenames exist. - _________________________________________________________________ - -cpp: Usage:... Error - - If you get an error like this when building GCC (particularly when - building __mulsi3), then you likely have a problem with your - environment variables. - cpp: Usage: /usr/lib/gcc-lib/i586-unknown-linux-gnulibc1/2.7.2.3/cpp - [switches] input output - - First look for an explicit '.' in either LIBRARY_PATH or - GCC_EXEC_PREFIX from your environment. If you do not find an explicit - '.', look for an empty pathname in those variables. Note that ':' at - either the start or end of these variables is an implicit '.' and will - cause problems. - - Also note '::' in these paths will also cause similar problems. - _________________________________________________________________ - -Optimizing the compiler itself - - If you want to test a particular optimization option, it's useful to - try bootstrapping the compiler with that option turned on. For - example, to test the -fssa option, you could bootstrap like this: -make BOOT_CFLAGS="-O2 -fssa" bootstrap - _________________________________________________________________ - - Testsuite problems - -Unable to run the testsuite - - If you get a message about unable to find "standard.exp" when trying - to run the GCC testsuites, then your dejagnu is too old to run the GCC - tests. You will need to get a newer version of dejagnu from - [47]http://www.gnu.org/software/dejagnu/dejagnu.html. - _________________________________________________________________ - -How do I pass flags like -fnew-abi to the testsuite? - - If you invoke runtest directly, you can use the --tool_opts option, - e.g: - runtest --tool_opts "-fnew-abi -fno-honor-std" - - Or, if you use make check you can use the make variable RUNTESTFLAGS, - e.g: - make RUNTESTFLAGS="--tool_opts '-fnew-abi -fno-honor-std'" check-g++ - _________________________________________________________________ - -How can I run the test suite with multiple options? - - If you invoke runtest directly, you can use the --target_board option, - e.g: - runtest --target_board "unix{-fPIC,-fpic,}" - - Or, if you use make check you can use the make variable RUNTESTFLAGS, - e.g: - make RUNTESTFLAGS="--target_board 'unix{-fPIC,-fpic,}'" check-gcc - - Either of these examples will run the tests three times. Once with - -fPIC, once with -fpic, and once with no additional flags. - - This technique is particularly useful on multilibbed targets. - _________________________________________________________________ - - Older versions of GCC and EGCS - -Is there a stringstream / sstream for GCC 2.95.2? - - Yes, it's at: - [48]http://gcc.gnu.org/ml/libstdc++/2000-q2/msg00700/sstream. - _________________________________________________________________ - - Miscellaneous - -Virtual memory exhausted error - - This error means your system ran out of memory; this can happen for - large files, particularly when optimizing. If you're getting this - error you should consider trying to simplify your files or reducing - the optimization level. - - Note that using -pedantic or -Wreturn-type can cause an explosion in - the amount of memory needed for template-heavy C++ code, such as code - that uses STL. Also note that -Wall includes -Wreturn-type, so if you - use -Wall you will need to specify -Wno-return-type to turn it off. - _________________________________________________________________ - -Friend Templates - - In order to make a specialization of a template function a friend of a - (possibly template) class, you must explicitly state that the friend - function is a template, by appending angle brackets to its name, and - this template function must have been declared already. Here's an - example: -template class foo { - friend void bar(foo); -} - - The above declaration declares a non-template function named bar, so - it must be explicitly defined for each specialization of foo. A - template definition of bar won't do, because it is unrelated with the - non-template declaration above. So you'd have to end up writing: -void bar(foo) { /* ... */ } -void bar(foo) { /* ... */ } - - If you meant bar to be a template function, you should have - forward-declared it as follows. Note that, since the template function - declaration refers to the template class, the template class must be - forward-declared too: -template -class foo; - -template -void bar(foo); - -template -class foo { - friend void bar<>(foo); -}; - -template -void bar(foo) { /* ... */ } - - In this case, the template argument list could be left empty, because - it can be implicitly deduced from the function arguments, but the - angle brackets must be present, otherwise the declaration will be - taken as a non-template function. Furthermore, in some cases, you may - have to explicitly specify the template arguments, to remove - ambiguity. - - An error in the last public comment draft of the ANSI/ISO C++ Standard - and the fact that previous releases of GCC would accept such friend - declarations as template declarations has led people to believe that - the forward declaration was not necessary, but, according to the final - version of the Standard, it is. - _________________________________________________________________ - -dynamic_cast, throw, typeid don't work with shared libraries - - The new C++ ABI in the GCC 3.0 series uses address comparisons, rather - than string compares, to determine type equality. This leads to better - performance. Like other objects that have to be present in the final - executable, these std::typeinfo_t objects have what is called vague - linkage because they are not tightly bound to any one particular - translation unit (object file). The compiler has to emit them in any - translation unit that requires their presence, and then rely on the - linking and loading process to make sure that only one of them is - active in the final executable. With static linking all of these - symbols are resolved at link time, but with dynamic linking, further - resolution occurs at load time. You have to ensure that objects within - a shared library are resolved against objects in the executable and - other shared libraries. - * For a program which is linked against a shared library, no - additional precautions need taking. - * You cannot create a shared library with the "-Bsymbolic" option, - as that prevents the resolution described above. - * If you use dlopen to explicitly load code from a shared library, - you must do several things. First, export global symbols from the - executable by linking it with the "-E" flag (you will have to - specify this as "-Wl,-E" if you are invoking the linker in the - usual manner from the compiler driver, g++). You must also make - the external symbols in the loaded library available for - subsequent libraries by providing the RTLD_GLOBAL flag to dlopen. - The symbol resolution can be immediate or lazy. - - Template instantiations are another, user visible, case of objects - with vague linkage, which needs similar resolution. If you do not take - the above precautions, you may discover that a template instantiation - with the same argument list, but instantiated in multiple translation - units, has several addresses, depending in which translation unit the - address is taken. (This is not an exhaustive list of the kind of - objects which have vague linkage and are expected to be resolved - during linking & loading.) - - If you are worried about different objects with the same name - colliding during the linking or loading process, then you should use - namespaces to disambiguate them. Giving distinct objects with global - linkage the same name is a violation of the One Definition Rule (ODR) - [basic.def.odr]. - - For more details about the way that GCC implements these and other C++ - features, please read the [49]ABI specification. Note the - std::typeinfo_t objects which must be resolved all begin with "_ZTS". - Refer to ld's documentation for a description of the "-E" & - "-Bsymbolic" flags. - _________________________________________________________________ - -Why do I need autoconf, bison, xgettext, automake, etc? - - If you're using diffs up dated from one snapshot to the next, or if - you're using the CVS repository, you may need several additional - programs to build GCC. - - These include, but are not necessarily limited to autoconf, automake, - bison, and xgettext. - - This is necessary because neither diff nor cvs keep timestamps - correct. This causes problems for generated files as "make" may think - those generated files are out of date and try to regenerate them. - - An easy way to work around this problem is to use the gcc_update - script in the contrib subdirectory of GCC, which handles this - transparently without requiring installation of any additional tools. - (Note: Up to and including GCC 2.95 this script was called egcs_update - .) - - When building from diffs or CVS or if you modified some sources, you - may also need to obtain development versions of some GNU tools, as the - production versions do not necessarily handle all features needed to - rebuild GCC. - - In general, the current versions of these tools from - [50]ftp://ftp.gnu.org/gnu/ will work. At present, Autoconf 2.50 is not - supported, and you will need to use Autoconf 2.13; work is in progress - to fix this problem. Also look at - [51]ftp://gcc.gnu.org/pub/gcc/infrastructure/ for any special versions - of packages. - _________________________________________________________________ - -Why can't I build a shared library? - - When building a shared library you may get an error message from the - linker like `assert pure-text failed:' or `DP relative code in file'. - - This kind of error occurs when you've failed to provide proper flags - to gcc when linking the shared library. - - You can get this error even if all the .o files for the shared library - were compiled with the proper PIC option. When building a shared - library, gcc will compile additional code to be included in the - library. That additional code must also be compiled with the proper - PIC option. - - Adding the proper PIC option (-fpic or -fPIC) to the link line which - creates the shared library will fix this problem on targets that - support PIC in this manner. For example: - gcc -c -fPIC myfile.c - gcc -shared -o libmyfile.so -fPIC myfile.o - _________________________________________________________________ - -How to work around too long C++ symbol names (-fsquangle) - - This question does not apply to GCC 3.0 or later versions, which have - a new C++ ABI with much shorter mangled names. - - If the standard assembler of your platform can't cope with the large - symbol names that the default g++ name mangling mechanism produces, - your best bet is to use GNU as, from the GNU binutils package. - - Unfortunately, GNU as does not support all platforms supported by GCC, - so you may have to use an experimental work-around: the -fsquangle - option, that enables compression of symbol names. - - Note that this option is still under development, and subject to - change. Since it modifies the name mangling mechanism, you'll need to - build libstdc++ and any other C++ libraries with this option enabled. - Furthermore, if this option changes its behavior in the future, you'll - have to rebuild them all again. :-( - - This option can be enabled by default by initializing - `flag_do_squangling' with `1' in `gcc/cp/decl2.c' (it is not - initialized by default), then rebuilding GCC and any C++ libraries. - _________________________________________________________________ - -When building C++, the linker says my constructors, destructors or virtual -tables are undefined, but I defined them - - The ISO C++ Standard specifies that all virtual methods of a class - that are not pure-virtual must be defined, but does not require any - diagnostic for violations of this rule [class.virtual]/8. Based on - this assumption, GCC will only emit the implicitly defined - constructors, the assignment operator, the destructor and the virtual - table of a class in the translation unit that defines its first such - non-inline method. - - Therefore, if you fail to define this particular method, the linker - may complain about the lack of definitions for apparently unrelated - symbols. Unfortunately, in order to improve this error message, it - might be necessary to change the linker, and this can't always be - done. - - The solution is to ensure that all virtual methods that are not pure - are defined. Note that a destructor must be defined even if it is - declared pure-virtual [class.dtor]/7. - _________________________________________________________________ - -Will GCC someday include an incremental linker? - - Incremental linking is part of the linker, not the compiler. As such, - GCC doesn't have anything to do with incremental linking. Depending on - what platform you use, it may be possible to tell GCC to use the - platform's native linker (e.g., Solaris' ild(1)). - -References - - 1. http://www.gnu.org/software/gcc/faq.html - 2. http://www.eskimo.com/~scs/C-faq/top.html - 3. http://www.research.att.com/~austern/csc/faq.html - 4. http://www.fortran.com/fortran/info.html - 5. http://gcc.gnu.org/onlinedocs/libstdc++/faq/index.html - 6. http://gcc.gnu.org/java/faq.html - 7. http://gcc.gnu.org/faq.html#general - 8. http://gcc.gnu.org/faq.html#gcc - 9. http://gcc.gnu.org/faq.html#cygnus - 10. http://gcc.gnu.org/faq.html#open-development - 11. http://gcc.gnu.org/faq.html#bugreport - 12. http://gcc.gnu.org/faq.html#support - 13. http://gcc.gnu.org/faq.html#platforms - 14. http://gcc.gnu.org/faq.html#installation - 15. http://gcc.gnu.org/faq.html#multiple - 16. http://gcc.gnu.org/faq.html#rpath - 17. http://gcc.gnu.org/faq.html#rpath - 18. http://gcc.gnu.org/faq.html#gas - 19. http://gcc.gnu.org/faq.html#environ - 20. http://gcc.gnu.org/faq.html#optimizing - 21. http://gcc.gnu.org/faq.html#testsuite - 22. http://gcc.gnu.org/faq.html#dejagnu - 23. http://gcc.gnu.org/faq.html#testoptions - 24. http://gcc.gnu.org/faq.html#multipletests - 25. http://gcc.gnu.org/faq.html#old - 26. http://gcc.gnu.org/faq.html#2.95sstream - 27. http://gcc.gnu.org/faq.html#misc - 28. http://gcc.gnu.org/faq.html#memexhausted - 29. http://gcc.gnu.org/faq.html#friend - 30. http://gcc.gnu.org/faq.html#dso - 31. http://gcc.gnu.org/faq.html#generated_files - 32. http://gcc.gnu.org/faq.html#picflag-needed - 33. http://gcc.gnu.org/faq.html#squangle - 34. http://gcc.gnu.org/faq.html#vtables - 35. http://gcc.gnu.org/faq.html#incremental - 36. http://gcc.gnu.org/steering.html - 37. http://gcc.gnu.org/steering.html - 38. http://gcc.gnu.org/faq.html#cathedral-vs-bazaar - 39. http://www.tuxedo.org/~esr/writings/cathedral-bazaar/ - 40. http://gcc.gnu.org/bugs.html - 41. http://gcc.gnu.org/bugs.html - 42. http://gcc.gnu.org/bugs.html - 43. http://gcc.gnu.org/install/specific.html - 44. http://gcc.gnu.org/buildstat.html - 45. http://gcc.gnu.org/faq.html#gas - 46. http://gcc.gnu.org/install/specific.html - 47. http://www.gnu.org/software/dejagnu/dejagnu.html - 48. http://gcc.gnu.org/ml/libstdc++/2000-q2/msg00700/sstream - 49. http://www.codesourcery.com/cxx-abi/ - 50. ftp://ftp.gnu.org/gnu/ - 51. ftp://gcc.gnu.org/pub/gcc/infrastructure/ diff --git a/contrib/gcc/GNATS b/contrib/gcc/GNATS deleted file mode 100644 index aa67bc9..0000000 --- a/contrib/gcc/GNATS +++ /dev/null @@ -1,187 +0,0 @@ - - Submitting Bug Reports using GNATS - -gnatsweb and gccbug - - GNATS, the GNU bug tracking system, is used to track GCC bug reports. - Before submitting a bug report, please read the [1]general - instructions. - - The preferred way to submit a bug report is by means of the - [2]gnatsweb interface.

Reporting Bugs

- -

Our preferred way of receiving bugs is via the -GCC GNATS bug reporting system.

- -

Before you report a bug, please check the -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 -GCC GNATS bug database. -Only if this is not possible, mail all information to -bug-gcc@gnu.org or -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 GCC GNATS bug -database.

- -

Detailed bug reporting instructions

- -

Please refer to the 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 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 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. -
  2. Add the test-case to our test-suite, marking it as XFAIL unless -the bug is a regression.
    3. -
  3. Add a bug report referencing the test-case to GNATS.
    4. -
- -

If you fix a bug for which there is already a GNATS entry:

-
    -
  1. Remove the XFAIL on the test-case.
    2. -
  2. Close the bug report in GNATS.
    3. -
- -

If you find a bug, and you are fixing it right then:

-
    -
  1. Create a (minimal) test-case.
    2. -
  2. Add the test-case to our test-suite, marking it as PASS.
    3. -
  3. Check in your fixes.
    4. -

Frequently Reported Bugs in GCC

- -

Fortran

- -

Fortran bugs are documented in the G77 manual rather than -explicitly listed here. Please see -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 -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. 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 -http://www.ncits.org/cplusplus.htm).

- -

We have also implemented some of the core and library defect reports -(available at -http://anubis.dkuug.dk/jtc1/sc22/wg21/docs/cwg_defects.html -& - -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. -
  2. The base object constructor/destructor.
    3. -
  3. The allocating destructor/deallocating destructor.
    4. -
-

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 -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.

General information

- -

What is the relationship between GCC and EGCS?

- -

In 1990/1991 gcc version 1 had reached a point of stability. For the -targets it could support, it worked well. It had limitations inherent in -its design that would be difficult to resolve, so a major effort was made -to resolve those limitiations and gcc version 2 was the result.

- -

When we had gcc2 in a useful state, development efforts on gcc1 stopped -and we all concentrated on making gcc2 better than gcc1 could ever be. This -is the kind of step forward we wanted to make with the EGCS project when it -was formed in 1997.

- -

In April 1999 the Free Software Foundation officially halted -development on the gcc2 compiler and appointed the EGCS project as the -official GCC maintainers. The net result was a single project which -carries forward GCC development under the ultimate control of the -GCC Steering Committee.

- - -
-

What is the relationship between GCC and Cygnus / Red Hat?

- -

It is a common mis-conception that Red Hat controls GCC either -directly or indirectly.

- -

While Red Hat does donate hardware, network connections, code and -developer time to GCC development, Red Hat does not control GCC.

- -

Overall control of GCC is in the hands of the -GCC Steering Committee -which includes people from a variety of different organizations and -backgrounds. The purpose of the steering committee is to make -decisions in the best interest of GCC and to help ensure that no -individual or company has control over the project.

- -

To summarize, Red Hat contributes to the GCC project, but does not exert -a controlling influence over GCC.

- -
-

What is an open development model?

- -

We are using a bazaar style -[1] -approach to GCC development: we make snapshots publicly available to -anyone who wants to try them; we welcome anyone to join -the development mailing list. All of the discussions on the -development mailing list are available via the web. We're going to be -making releases with a much higher frequency than they have been made -in the past.

- -

In addition to weekly snapshots of the GCC development sources, we -have the sources readable from a CVS server by anyone. Furthermore we -are using remote CVS to allow remote maintainers write access to the -sources.

- -

There have been many potential GCC developers who were not able to -participate in GCC development in the past. We want these people to -help in any way they can; we ultimately want GCC to be the best compiler -in the world.

- -

A compiler is a complicated piece of software, there will still be -strong central maintainers who will reject patches, who will demand -documentation of implementations, and who will keep the level of -quality as high as it is today. Code that could use wider testing may -be integrated--code that is simply ill-conceived won't be.

- -

GCC is not the first piece of software to use this open development -process; FreeBSD, the Emacs lisp repository, and the Linux kernel are -a few examples of the bazaar style of development.

- -

With GCC, we are adding new features and optimizations at a -rate that has not been done since the creation of gcc2; these -additions inevitably have a temporarily destabilizing effect. -With the help of developers working together with this bazaar style -development, the resulting stability and quality levels will be better -than we've had before.

- -
-[1] - We've been discussing different development models a lot over the - past few months. The paper which started all of this introduced two - terms: A cathedral development model versus a bazaar - development model. The paper is written by Eric S. Raymond, it is - called ``The - Cathedral and the Bazaar''. The paper is a useful starting point - for discussions. -
- - -
-

How do I report a bug?

- -

There are complete instructions here.

- - -
-

How do I get a bug fixed or a feature added?

- -

There are lots of ways to get something fixed. The list below may be -incomplete, but it covers many of the common cases. These are listed -roughly in order of increasing difficulty for the average GCC user, -meaning someone who is not skilled in the internals of GCC, and where -difficulty is measured in terms of the time required to fix the bug. -No alternative is better than any other; each has its benefits and -disadvantages.

- -
    -
  • Hire someone to fix it for you. There are various companies and - individuals providing support for GCC. This alternative costs - money, but is relatively likely to get results.
    • - -
  • Report the problem to the GCC GNATS bug tracking system - and hope that someone will be kind - enough to fix it for you. While this is certainly possible, and - often happens, there is no guarantee that it will. You should - not expect the same response from this method that you would see - from a commercial support organization since the people who read - GCC bug reports, if they choose to help you, will be volunteering their - time. This alternative will work best if you follow the directions - on submitting bugreports.
    • - -
  • Fix it yourself. This alternative will probably bring results, - if you work hard enough, but will probably take a lot of time, - and, depending on the quality of your work and the perceived - benefits of your changes, your code may or may not ever make it - into an official release of GCC.
    • -
- -
- -

Does GCC work on my platform?

- -

The host/target specific installation notes for GCC include information -about known problems with installing or using GCC on particular platforms. -These are included in the sources for a release in INSTALL/specific.html, -and the latest version -is always available at the GCC web site. -Reports of successful builds -for several versions of GCC are also available at the web site.

- -
- -

Installation

- -

How to install multiple versions of GCC

- -

It may be desirable to install multiple versions of the compiler on -the same system. This can be done by using different prefix paths at -configure time and a few symlinks.

- -

Basically, configure the two compilers with different --prefix options, -then build and install each compiler. Assume you want "gcc" to be the latest -compiler and available in /usr/local/bin; also assume that you want "gcc2" -to be the older gcc2 compiler and also available in /usr/local/bin.

- -

The easiest way to do this is to configure the new GCC with ---prefix=/usr/local/gcc and the older gcc2 with ---prefix=/usr/local/gcc2. Build and install both -compilers. Then make a symlink from /usr/local/bin/gcc -to /usr/local/gcc/bin/gcc and from -/usr/local/bin/gcc2 to -/usr/local/gcc2/bin/gcc. Create similar links for the -"g++", "c++" and "g77" compiler drivers.

- -

An alternative to using symlinks is to configure with a ---program-transform-name option. This option specifies a -sed command to process installed program names with. Using it you can, -for instance, have all the new GCC programs installed as "new-gcc" and -the like. You will still have to specify different ---prefix options for new GCC and old GCC, because it is -only the executable program names that are transformed. The difference -is that you (as administrator) do not have to set up symlinks, but -must specify additional directories in your (as a user) PATH. A -complication with --program-transform-name is that the -sed command invariably contains characters significant to the shell, -and these have to be escaped correctly, also it is not possible to use -"^" or "$" in the command. Here is the option to prefix "new-" to the -new GCC installed programs:

-
---program-transform-name='s,\\\\(.*\\\\),new-\\\\1,' -
-

With the above --prefix option, that will install the new -GCC programs into /usr/local/gcc/bin with names prefixed -by "new-". You can use --program-transform-name if you -have multiple versions of GCC, and wish to be sure about which version -you are invoking.

- -

If you use --prefix, GCC may have difficulty locating a GNU -assembler or linker on your system, GCC can not find GNU -as/GNU ld explains how to deal with this.

- -

Another option that may be easier is to use the ---program-prefix= or --program-suffix= -options to configure. So if you're installing GCC 2.95.2 and don't -want to disturb the current version of GCC in -/usr/local/bin/, you could do

-
-configure --program-suffix=-2.95.2 <other configure options> -
-

This should result in GCC being installed as -/usr/local/bin/gcc-2.95.2 instead of -/usr/local/bin/gcc.

- -
-

Dynamic linker is unable to find GCC libraries

- -

This problem manifests itself by programs not finding shared -libraries they depend on when the programs are started. Note this -problem often manifests itself with failures in the libio/libstdc++ -tests after configuring with --enable-shared and building GCC.

- -

GCC does not specify a runpath so that the dynamic linker can find -dynamic libraries at runtime.

- -

The short explanation is that if you always pass a -R option to the -linker, then your programs become dependent on directories which -may be NFS mounted, and programs may hang unnecessarily when an -NFS server goes down.

- -

The problem is not programs that do require the directories; those -programs are going to hang no matter what you do. The problem is -programs that do not require the directories.

- -

SunOS effectively always passed a -R option for every --L option; this was a bad idea, and so it was removed for -Solaris. We should not recreate it.

- -

However, if you feel you really need such an option to be passed -automatically to the linker, you may add it to the GCC specs file. -This file can be found in the same directory that contains cc1 (run -gcc -print-prog-name=cc1 to find it). You may add linker -flags such as -R or -rpath, depending on -platform and linker, to the *link or *lib -specs.

- -

Another alternative is to install a wrapper script around gcc, g++ -or ld that adds the appropriate directory to the environment variable -LD_RUN_PATH or equivalent (again, it's -platform-dependent).

- -

Yet another option, that works on a few platforms, is to hard-code -the full pathname of the library into its soname. This can only be -accomplished by modifying the appropriate .ml file within -libstdc++/config (and also libg++/config, if you are -building libg++), so that $(libdir)/ appears just before -the library name in -soname or -h options.

- -
-

GCC can not find GNU as/GNU ld

-

GCC searches the PATH for an assembler and a loader, but it only -does so after searching a directory list hard-coded in the GCC -executables. Since, on most platforms, the hard-coded list includes -directories in which the system asembler and loader can be found, you -may have to take one of the following actions to arrange that GCC uses -the GNU versions of those programs.

- -

To ensure that GCC finds the GNU assembler (the GNU loader), which -are required by some -configurations, -you should configure these with the same --prefix option as you used -for GCC. Then build & install GNU as (GNU ld) and proceed with -building GCC.

- -

Another alternative is to create links to GNU as and ld in any of -the directories printed by the command `gcc -print-search-dirs | -grep '^programs:''. The link to `ld' should be named -`real-ld' if `ld' already exists. If such links do -not exist while you're compiling GCC, you may have to create them in -the build directories too, within the gcc directory -and in all the gcc/stage* subdirectories.

- -

GCC 2.95 allows you to specify the full pathname of the assembler -and the linker to use. The configure flags are -`--with-as=/path/to/as' and `--with-ld=/path/to/ld'. -GCC will try to use these pathnames before looking for `as' -or `(real-)ld' in the standard search dirs. If, at -configure-time, the specified programs are found to be GNU utilities, -`--with-gnu-as' and `--with-gnu-ld' need not be -used; these flags will be auto-detected. One drawback of this option -is that it won't allow you to override the search path for assembler -and linker with command-line options -B/path/ if the -specified filenames exist.

- -
-

cpp: Usage:... Error

- -

If you get an error like this when building GCC (particularly when building -__mulsi3), then you likely have a problem with your environment variables.

-
-  cpp: Usage: /usr/lib/gcc-lib/i586-unknown-linux-gnulibc1/2.7.2.3/cpp
-  [switches] input output
-
-

First look for an explicit '.' in either LIBRARY_PATH or GCC_EXEC_PREFIX -from your environment. If you do not find an explicit '.', look for -an empty pathname in those variables. Note that ':' at either the start -or end of these variables is an implicit '.' and will cause problems.

- -

Also note '::' in these paths will also cause similar problems.

- - -
-

Optimizing the compiler itself

- -

If you want to test a particular optimization option, it's useful to try -bootstrapping the compiler with that option turned on. For example, to -test the -fssa option, you could bootstrap like this:

- -
make BOOT_CFLAGS="-O2 -fssa" bootstrap
- - -
- -

Testsuite problems

- -

Unable to run the testsuite

- -

If you get a message about unable to find "standard.exp" when trying to -run the GCC testsuites, then your dejagnu is too old to run the GCC tests. -You will need to get a newer version of dejagnu from - - http://www.gnu.org/software/dejagnu/dejagnu.html.

- -
-

How do I pass flags like - -fnew-abi to the testsuite?

- -

If you invoke runtest directly, you can use the ---tool_opts option, e.g:

-
-  runtest --tool_opts "-fnew-abi -fno-honor-std" <other options>
-
-

Or, if you use make check you can use the -make variable RUNTESTFLAGS, e.g:

-
-  make RUNTESTFLAGS="--tool_opts '-fnew-abi -fno-honor-std'" check-g++
-
- -
-

How can I run the test suite with multiple options?

- -

If you invoke runtest directly, you can use the ---target_board option, e.g:

-
-  runtest --target_board "unix{-fPIC,-fpic,}" <other options>
-
-

Or, if you use make check you can use the -make variable RUNTESTFLAGS, e.g:

-
-  make RUNTESTFLAGS="--target_board 'unix{-fPIC,-fpic,}'" check-gcc
-
-

Either of these examples will run the tests three times. Once -with -fPIC, once with -fpic, and once with -no additional flags.

- -

This technique is particularly useful on multilibbed targets.

- -
- -

Older versions of GCC and EGCS

- -

Is there a stringstream / sstream for GCC 2.95.2?

- -

Yes, it's at: - - http://gcc.gnu.org/ml/libstdc++/2000-q2/msg00700/sstream.

- -
- -

Miscellaneous

- - - -

Virtual memory exhausted error

- -

This error means your system ran out of memory; this can happen for large -files, particularly when optimizing. If you're getting this error you should -consider trying to simplify your files or reducing the optimization level.

- -

Note that using -pedantic or -Wreturn-type can cause an explosion in the -amount of memory needed for template-heavy C++ code, such as code that uses -STL. Also note that -Wall includes -Wreturn-type, so if you use -Wall you -will need to specify -Wno-return-type to turn it off.

- - -
-

Friend Templates

- -

In order to make a specialization of a template function a friend -of a (possibly template) class, you must explicitly state that the -friend function is a template, by appending angle brackets to its -name, and this template function must have been declared already. -Here's an example:

-
-template <typename T> class foo {
-  friend void bar(foo<T>);
-}

The above declaration declares a non-template function named -bar, so it must be explicitly defined for each -specialization of foo. A template definition of bar -won't do, because it is unrelated with the non-template declaration -above. So you'd have to end up writing:

-
-void bar(foo<int>) { /* ... */ }
-void bar(foo<void>) { /* ... */ }
-
-

If you meant bar to be a template function, you should -have forward-declared it as follows. Note that, since the template -function declaration refers to the template class, the template class -must be forward-declared too:

-
-template <typename T>
-class foo;
-
-template <typename T>
-void bar(foo<T>);
-
-template <typename T>
-class foo {
-  friend void bar<>(foo<T>);
-};
-
-template <typename T>
-void bar(foo<T>) { /* ... */ }
-
-

In this case, the template argument list could be left empty, -because it can be implicitly deduced from the function arguments, but -the angle brackets must be present, otherwise the declaration will be -taken as a non-template function. Furthermore, in some cases, you may -have to explicitly specify the template arguments, to remove -ambiguity.

- -

An error in the last public comment draft of the ANSI/ISO C++ -Standard and the fact that previous releases of GCC would accept such -friend declarations as template declarations has led people to believe -that the forward declaration was not necessary, but, according to the -final version of the Standard, it is.

dynamic_cast, throw, typeid don't work with shared libraries

- -

The new C++ ABI in the GCC 3.0 series uses address comparisons, -rather than string compares, to determine type equality. This leads -to better performance. Like other objects that have to be present in the -final executable, these std::typeinfo_t objects have what -is called vague linkage because they are not tightly bound to any one -particular translation unit (object file). The compiler has to emit -them in any translation unit that requires their presence, and then -rely on the linking and loading process to make sure that only one of -them is active in the final executable. With static linking all of -these symbols are resolved at link time, but with dynamic linking, -further resolution occurs at load time. You have to ensure that -objects within a shared library are resolved against objects in the -executable and other shared libraries.

- -
    -
  • For a program which is linked against a shared library, no additional -precautions need taking.
    • - -
  • You cannot create a shared library with the "-Bsymbolic" -option, as that prevents the resolution described above.
    • - -
  • If you use dlopen to explicitly load code from a shared -library, you must do several things. First, export global symbols from -the executable by linking it with the "-E" flag (you will -have to specify this as "-Wl,-E" if you are invoking -the linker in the usual manner from the compiler driver, g++). -You must also make the external symbols in the loaded library -available for subsequent libraries by providing the RTLD_GLOBAL -flag to dlopen. The symbol resolution can be immediate or -lazy.
    • - -
- -

Template instantiations are another, user visible, case of objects -with vague linkage, which needs similar resolution. If you do not take -the above precautions, you may discover that a template instantiation -with the same argument list, but instantiated in multiple translation -units, has several addresses, depending in which translation unit the -address is taken. (This is not an exhaustive list of the kind -of objects which have vague linkage and are expected to be resolved -during linking & loading.)

- -

If you are worried about different objects with the same name -colliding during the linking or loading process, then you should use -namespaces to disambiguate them. Giving distinct objects with global -linkage the same name is a violation of the One Definition Rule (ODR) -[basic.def.odr].

- -

For more details about the way that GCC implements these and other -C++ features, please read the ABI specification. -Note the std::typeinfo_t objects which must be -resolved all begin with "_ZTS". Refer to ld's -documentation for a description of the "-E" & -"-Bsymbolic" flags.

Why do I need autoconf, bison, xgettext, automake, etc?

- -

If you're using diffs up dated from one snapshot to the next, or -if you're using the CVS repository, you may need several additional programs -to build GCC.

- -

These include, but are not necessarily limited to autoconf, automake, -bison, and xgettext.

- -

This is necessary because neither diff nor cvs keep timestamps -correct. This causes problems for generated files as "make" may think -those generated files are out of date and try to regenerate them.

- -

An easy way to work around this problem is to use the gcc_update - script in the contrib subdirectory of GCC, which handles this -transparently without requiring installation of any additional tools. -(Note: Up to and including GCC 2.95 this script was called egcs_update -.)

- - -

When building from diffs or CVS or if you modified some sources, -you may also need to obtain development versions of some GNU tools, as -the production versions do not necessarily handle all features needed -to rebuild GCC.

- -

In general, the current versions of these tools from ftp://ftp.gnu.org/gnu/ will work. -At present, Autoconf 2.50 is not supported, and you will need to use -Autoconf 2.13; work is in progress to fix this problem. Also look at - -ftp://gcc.gnu.org/pub/gcc/infrastructure/ for any special versions -of packages.

- - -
-

Why can't I build a shared library?

- -

When building a shared library you may get an error message from the -linker like `assert pure-text failed:' or `DP relative code in file'.

- -

This kind of error occurs when you've failed to provide proper flags -to gcc when linking the shared library.

- -

You can get this error even if all the .o files for the shared library were -compiled with the proper PIC option. When building a shared library, gcc will -compile additional code to be included in the library. That additional code -must also be compiled with the proper PIC option.

- -

Adding the proper PIC option (-fpic or -fPIC) to the link -line which creates the shared library will fix this problem on targets that -support PIC in this manner. For example:

-
-	gcc -c -fPIC myfile.c
-	gcc -shared -o libmyfile.so -fPIC myfile.o
-

How to work around too long C++ symbol names -(-fsquangle)

- -

This question does not apply to GCC 3.0 or later versions, which -have a new C++ ABI with much shorter mangled names.

- -

If the standard assembler of your platform can't cope with the -large symbol names that the default g++ name mangling mechanism -produces, your best bet is to use GNU as, from the GNU binutils -package.

- -

Unfortunately, GNU as does not support all platforms supported by -GCC, so you may have to use an experimental work-around: the --fsquangle option, that enables compression of symbol names.

- -

Note that this option is still under development, and subject to -change. Since it modifies the name mangling mechanism, you'll need to -build libstdc++ and any other C++ libraries with this option enabled. -Furthermore, if this option changes its behavior in the future, you'll -have to rebuild them all again. :-(

- -

This option can be enabled by default by initializing -`flag_do_squangling' with `1' in `gcc/cp/decl2.c' (it is not -initialized by default), then rebuilding GCC and any C++ libraries.

- - -
-

When building C++, the linker says my constructors, destructors or virtual tables are undefined, but I defined them

- -

The ISO C++ Standard specifies that all virtual methods of a class -that are not pure-virtual must be defined, but does not require any -diagnostic for violations of this rule [class.virtual]/8. Based on -this assumption, GCC will only emit the implicitly defined -constructors, the assignment operator, the destructor and the virtual -table of a class in the translation unit that defines its first such -non-inline method.

- -

Therefore, if you fail to define this particular method, the linker -may complain about the lack of definitions for apparently unrelated -symbols. Unfortunately, in order to improve this error message, it -might be necessary to change the linker, and this can't always be -done.

- -

The solution is to ensure that all virtual methods that are not -pure are defined. Note that a destructor must be defined even if it -is declared pure-virtual [class.dtor]/7.

- - -
-

Will GCC someday include an incremental linker?

- -

Incremental linking is part of the linker, not the compiler. As -such, GCC doesn't have anything to do with incremental linking. -Depending on what platform you use, it may be possible to tell GCC to -use the platform's native linker (e.g., Solaris' ild(1)).

Submitting Bug Reports using GNATS

- - -

gnatsweb and gccbug

- -

GNATS, the GNU bug tracking system, is used to track GCC bug reports. -Before submitting a bug report, please read the general instructions.

- -

The preferred way to submit a bug report is by means of the -gnatsweb -interface. Make sure you include an e-mail address, so we can inform -you when the status of your report changes.

(Exception: if the Program itself is interactive but - does not normally print such an announcement, your work based on - the Program is not required to print an announcement.) - -These requirements apply to the modified work as a whole. If -identifiable sections of that work are not derived from the Program, -and can be reasonably considered independent and separate works in -themselves, then this License, and its terms, do not apply to those -sections when you distribute them as separate works. But when you -distribute the same sections as part of a whole which is a work based -on the Program, the distribution of the whole must be on the terms of -this License, whose permissions for other licensees extend to the -entire whole, and thus to each and every part regardless of who wrote it. - -Thus, it is not the intent of this section to claim rights or contest -your rights to work written entirely by you; rather, the intent is to -exercise the right to control the distribution of derivative or -collective works based on the Program. - -In addition, mere aggregation of another work not based on the Program -with the Program (or with a work based on the Program) on a volume of -a storage or distribution medium does not bring the other work under -the scope of this License. - - 3. You may copy and distribute the Program (or a work based on it, -under Section 2) in object code or executable form under the terms of -Sections 1 and 2 above provided that you also do one of the following: - - a) Accompany it with the complete corresponding machine-readable - source code, which must be distributed under the terms of Sections - 1 and 2 above on a medium customarily used for software interchange; or, - - b) Accompany it with a written offer, valid for at least three - years, to give any third party, for a charge no more than your - cost of physically performing source distribution, a complete - machine-readable copy of the corresponding source code, to be - distributed under the terms of Sections 1 and 2 above on a medium - customarily used for software interchange; or, - - c) Accompany it with the information you received as to the offer - to distribute corresponding source code. (This alternative is - allowed only for noncommercial distribution and only if you - received the program in object code or executable form with such - an offer, in accord with Subsection b above.) - -The source code for a work means the preferred form of the work for -making modifications to it.

However, as a -special exception, the source code distributed need not include -anything that is normally distributed (in either source or binary -form) with the major components (compiler, kernel, and so on) of the -operating system on which the executable runs, unless that component -itself accompanies the executable. - -If distribution of executable or object code is made by offering -access to copy from a designated place, then offering equivalent -access to copy the source code from the same place counts as -distribution of the source code, even though third parties are not -compelled to copy the source along with the object code. - - 4. You may not copy, modify, sublicense, or distribute the Program -except as expressly provided under this License. Any attempt -otherwise to copy, modify, sublicense or distribute the Program is -void, and will automatically terminate your rights under this License. -However, parties who have received copies, or rights, from you under -this License will not have their licenses terminated so long as such -parties remain in full compliance. - - 5. You are not required to accept this License, since you have not -signed it. However, nothing else grants you permission to modify or -distribute the Program or its derivative works.

If you cannot -distribute so as to satisfy simultaneously your obligations under this -License and any other pertinent obligations, then as a consequence you -may not distribute the Program at all. For example, if a patent -license would not permit royalty-free redistribution of the Program by -all those who receive copies directly or indirectly through you, then -the only way you could satisfy both it and this License would be to -refrain entirely from distribution of the Program. - -If any portion of this section is held invalid or unenforceable under -any particular circumstance, the balance of the section is intended to -apply and the section as a whole is intended to apply in other -circumstances. - -It is not the purpose of this section to induce you to infringe any -patents or other property right claims or to contest validity of any -such claims; this section has the sole purpose of protecting the -integrity of the free software distribution system, which is -implemented by public license practices.

If the distribution and/or use of the Program is restricted in -certain countries either by patents or by copyrighted interfaces, the -original copyright holder who places the Program under this License -may add an explicit geographical distribution limitation excluding -those countries, so that distribution is permitted only in or among -countries not thus excluded. In such case, this License incorporates -the limitation as if written in the body of this License. - - 9. The Free Software Foundation may publish revised and/or new versions -of the General Public License from time to time. Such new versions will -be similar in spirit to the present version, but may differ in detail to -address new problems or concerns. - -Each version is given a distinguishing version number. If the Program -specifies a version number of this License which applies to it and "any -later version", you have the option of following the terms and conditions -either of that version or of any later version published by the Free -Software Foundation. If the Program does not specify a version number of -this License, you may choose any version ever published by the Free Software -Foundation. - - 10. If you wish to incorporate parts of the Program into other free -programs whose distribution conditions are different, write to the author -to ask for permission. For software which is copyrighted by the Free -Software Foundation, write to the Free Software Foundation; we sometimes -make exceptions for this. Our decision will be guided by the two goals -of preserving the free status of all derivatives of our free software and -of promoting the sharing and reuse of software generally. - - NO WARRANTY - - 11.

The idea -is that you would use these pre-tested macros to solve a -very specific set of problems, and they would run fast. -Caution: no side-effects in arguments please!! They may be -evaluated MANY times!! - -These macros operate a stack of objects. Each object starts life -small, and may grow to maturity. (Consider building a word syllable -by syllable.) An object can move while it is growing. Once it has -been "finished" it never changes address again. So the "top of the -stack" is typically an immature growing object, while the rest of the -stack is of mature, fixed size and fixed address objects. - -These routines grab large chunks of memory, using a function you -supply, called `obstack_chunk_alloc'. On occasion, they free chunks, -by calling `obstack_chunk_free'. You must define them and declare -them before using any obstack macros. - -Each independent stack is represented by a `struct obstack'. -Each of the obstack macros expects a pointer to such a structure -as the first argument. - -One motivation for this package is the problem of growing char strings -in symbol tables. Unless you are "fascist pig with a read-only mind" ---Gosper's immortal quote from HAKMEM item 154, out of context--you -would not like to put any arbitrary upper limit on the length of your -symbols. - -In practice this often means you will build many short symbols and a -few long symbols. At the time you are reading a symbol you don't know -how long it is. One traditional method is to read a symbol into a -buffer, realloc()ating the buffer every time you try to read a symbol -that is longer than the buffer. This is beaut, but you still will -want to copy the symbol from the buffer to a more permanent -symbol-table entry say about half the time. - -With obstacks, you can work differently. Use one obstack for all symbol -names. As you read a symbol, grow the name in the obstack gradually. -When the name is complete, finalize it. Then, if the symbol exists already, -free the newly read name. - -The way we do this is to take a large chunk, allocating memory from -low addresses. When you want to build a symbol in the chunk you just -add chars above the current "high water mark" in the chunk. When you -have finished adding chars, because you got to the end of the symbol, -you know how long the chars are, and you can create a new object. -Mostly the chars will not burst over the highest address of the chunk, -because you would typically expect a chunk to be (say) 100 times as -long as an average object. - -In case that isn't clear, when we have enough chars to make up -the object, THEY ARE ALREADY CONTIGUOUS IN THE CHUNK (guaranteed) -so we just point to it where it lies. No moving of chars is -needed and this is the second win: potentially long strings need -never be explicitly shuffled. Once an object is formed, it does not -change its address during its lifetime. - -When the chars burst over a chunk boundary, we allocate a larger -chunk, and then copy the partly formed object from the end of the old -chunk to the beginning of the new larger chunk. We then carry on -accreting characters to the end of the object as we normally would. - -A special macro is provided to add a single char at a time to a -growing object. This allows the use of register variables, which -break the ordinary 'growth' macro. - -Summary: - We allocate large chunks. - We carve out one object at a time from the current chunk. - Once carved, an object never moves. - We are free to append data of any size to the currently - growing object. - Exactly one object is growing in an obstack at any one time. - You can run one obstack per control block. - You may have as many control blocks as you dare. - Because of the way we do it, you can `unwind' an obstack - back to a previous state.

This primarily helps targets which generate lots of -spills (like the x86 ports and many register poor embedded ports). - -A few changes in the heuristics used by the register allocator and scheduler -have been made which can significantly improve performance for certain -applications. - -The compiler's branch shortening algorithms have been significantly improved -to work better on targets which align jump targets. +Changes in GCC for EGCS (that are not listed in the web release notes) +--------------------------------------------------------------------- The compiler now supports the "ADDRESSOF" optimization which can significantly reduce the overhead for certain inline calls (and inline calls in general). -The compiler now supports a code size optimization switch (-Os). When enabled -the compiler will prefer optimizations which improve code size over those -which improve code speed. - -The compiler has been improved to completely eliminate library calls which -compute constant values. This is particularly useful on machines which -do not have integer mul/div or floating point support on-chip. - -GCC now supports a "--help" option to print detailed help information. - -cpplib has been greatly improved. It is probably usable for some sites now -(major missing feature is trigraphs). - -Memory footprint for the compiler has been significantly reduced for certain -pathalogical cases. - -Build time improvements for targets which support lots of sched parameters -(alpha and mips primarily). - Compile time for certain programs using large constant initializers has been improved (affects glibc significantly). -Plus an incredible number of infrastructure changes, warning fixes, bugfixes -and local optimizations. - Various improvements have been made to better support cross compilations. They are still not easy, but they are improving. -Target specific NEWS - - Sparc: Now includes V8 plus and V9 support, lots of tuning for Ultrasparcs - and uses the Haifa scheduler by default. - - Alpha: EV6 tuned, optimized expansion of memcpy/bzero. - - x86: Data in the static store is aligned per Intel recommendations. Jump - targets are aligned per Intel recommendations. Improved epilogue - sequences for Pentium chips. Backend improvements which should help - register allocation on all x86 variants. Support for PPro conditional - move instructions has been fixed and enabled. Random changes - throughout the port to make generated code more Pentium friendly. - Improved support for 64bit integer operations. - Unixware 7, a System V Release 5 target is now supported. - SCO OpenServer targets can support GAS. See gcc/INSTALL for details. - - RS6000/PowerPC: Includes AIX4.3 support as well as PowerPC64 support. - Haifa instruction scheduling is enabled by default now. - - MIPS: Multiply/Multiply-Add support has been largely rewritten to generate - more efficient code. Includes mips16 support. - - M68K: Various micro-optimizations and Coldfire fixes. +Target-specific changes: M32r: Major improvements to this port.

The nature of this bugged code is to rely on sizeof() + returning the correct size of various structures rounded to the + nearest byte (SCSI and ether code are two examples, the vm system + is another). This code breaks when the structure alignment is 32 + as sizeof() will report a word=rounded size. By changing the + structure alignment to 8. GCC will conform to what is expected by + NetBSD. + + This has several side effects that should be considered. + 1. Structures will only be aligned to the size of the largest member. + i.e. structures containing only bytes will be byte aligned. + structures containing shorts will be half word alinged. + structures containing ints will be word aligned. + + This means structures should be padded to a word boundary if + alignment of 32 is required for byte structures etc. + + 2. A potential performance penalty may exist if strings are no longer + word aligned. GCC will not be able to use word load/stores to copy + short strings. + + This modification is not encouraged but with the present state of the + NetBSD source tree it is currently the only solution that meets the + requirements. */ + +#undef DEFAULT_STRUCTURE_SIZE_BOUNDARY +#define DEFAULT_STRUCTURE_SIZE_BOUNDARY 8 + +/* Emit code to set up a trampoline and synchronize the caches. */ +#undef INITIALIZE_TRAMPOLINE +#define INITIALIZE_TRAMPOLINE(TRAMP, FNADDR, CXT) \ +do \ + { \ + emit_move_insn (gen_rtx (MEM, SImode, plus_constant ((TRAMP), 8)), \ + (CXT)); \ + emit_move_insn (gen_rtx (MEM, SImode, plus_constant ((TRAMP), 12)), \ + (FNADDR)); \ + emit_library_call (gen_rtx_SYMBOL_REF (Pmode, "__clear_cache"), \ + 0, VOIDmode, 2, TRAMP, Pmode, \ + plus_constant (TRAMP, TRAMPOLINE_SIZE), Pmode); \ + } \ +while (0) + +/* Clear the instruction cache from `BEG' to `END'.
