* build-many-glibcs.py: Do not build C++ PCHs by defaultFlorian Weimer2019-12-181-2/+5
| | | | | They are not used during the subsequent glibc build, so creating them merely wastes time.
* build-many-glibcs.py: Add mipsisa64r6el-linux-gnu targetDragan Mladjenovic2019-12-161-0/+11
| | | | | This patch enables building mips/r6 isa/little-endian/hard-float configuration in o32, n32, and n64 variants.
* build-many-glibcs.py: Move sparcv8 to extra_glibcsAdhemerval Zanella2019-12-051-4/+5
| | | | | | | | | | | It also fixes the sparcv9-linux-gnu-disable-multi-arch configuration. The resulting sparc possible build permutations are: - sparc64-linux-gnu - sparcv9-linux-gnu - sparcv8-linux-gnu-leon3 (from extra_glibcs) - sparc64-linux-gnu-disable-multi-arch (from extra_glibcs) - sparcv9-linux-gnu-disable-multi-arch (from extra_glibcs)
* Fix syntax error in build-many-glibcs.py.Joseph Myers2019-11-281-1/+1
| | | | | | | | | | The recent SPARC changes caused a syntax error: 'ccopts': '-m32 -mlong-double-128 -mcpu=v9'}], ^ SyntaxError: invalid syntax Fixed by this patch.
* Remove 32 bit sparc v7 supportAdhemerval Zanella2019-11-271-6/+4
| | | | | | | | | | | | | | | | | | The patch is straighforward: - The sparc32 v8 implementations are moved as the generic ones. - A configure test is added to check for either __sparc_v8__ or __sparc_v9__. - The triple names are simplified and sparc implies sparcv8. The idea is to keep support on sparcv8 architectures that does support CAS instructions, such as LEON3/LEON4. Checked on a sparcv9-linux-gnu and sparc64-linux-gnu.

* Script to generate ChangeLog-like output from git logSiddhesh Poyarekar2019-09-205-0/+1244
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Co-authored-by: Gabriel F. T. Gomes <gabriel@inconstante.net.br> Reviewed-by: Gabriel F. T. Gomes <gabriel@inconstante.net.br> Reviewed-by: Joseph Myers <joseph@codesourcery.com> The utility of a ChangeLog file has been discussed in various mailing list threads and GNU Tools Cauldrons in the past years and the general consensus is that while the file may have been very useful in the past when revision control did not exist or was not as powerful as it is today, it's current utility is fast diminishing. Further, the ChangeLog format gets in the way of modernisation of processes since it almost always results in rewriting of a commit, thus preventing use of any code review tools to automatically manage patches in the glibc project. There is consensus in the glibc community that documentation of why a change was done (i.e. a detailed description in a git commit) is more useful than what changed (i.e. a ChangeLog entry) since the latter can be deduced from the patch. The GNU community would however like to keep the option of ascertaining what changed through a ChangeLog-like output and as a compromise, it was proposed that a script be developed that generates this output. The script below is the result of these discussions. This script takes two git revisions references as input and generates the git log between those revisions in a form that resembles a ChangeLog. Its capabilities and limitations are listed in a comment in the script. On a high level it is capable of parsing C code and telling what changed at the top level, but not within constructs such as functions. Design ------ At a high level, the script analyses the raw output of a VCS, parses the source files that have changed and attempts to determine what changed. The script driver needs three distinct components to be fully functional for a repository: - A vcstocl_quirks.py file that helps it parse weird patterns in sources that may result from preprocessor defines. - A VCS plugin backend; the git backend is implemented for glibc - A programming language parser plugin. C is currently implemented. Additional programming language parsers can be added to give more detailed output for changes in those types of files. For input in languages other than those that have a parser, the script only identifies if a file has been added, removed, modified, permissions changed, etc. but cannot understand the change in content. The C Parser ------------ The C parser is capable of parsing C programs with preprocessor macros in place, as if they were part of the language. This presents some challenges with parsing code that expands macros on the fly and to help work around that, a vcstocl_quirks.py file has transformations to ease things. The C parser currently can identify macro definitions and scopes and all global and static declarations and definitions. It cannot parse (and compare) changes inside functions yet, it could be a future enhancement if the need for it arises. Testing ------- The script has been tested with the glibc repository up to glibc-2.29 and also in the past with emacs. While it would be ideal to have something like this in a repository like gnulib, that should not be a bottleneck for glibc to start using this, so this patch proposes to add these scripts into glibc. And here is (hopefully!) one of the last ChangeLog entries we'd have to write for glibc: * scripts/gitlog_to_changelog.py: New script to auto-generate ChangeLog. * scripts/vcs_to_changelog/frontend_c.py: New file. * scripts/vcs_to_changelog/misc_util.py: New file. * scripts/vcs_to_changelog/vcs_git.py: New file. * scripts/vcs_to_changelog/vcstocl_quirks.py: Likewise.

* Remove support for PowerPC SPE extension (powerpc*-*-*gnuspe*).Zack Weinberg2019-05-221-9/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | GCC 9 dropped support for the SPE extensions to PowerPC, which means powerpc*-*-*gnuspe* configurations are no longer buildable with that compiler. This ISA extension was peculiar to the “e500” line of embedded PowerPC chips, which, as far as I can tell, are no longer being manufactured, so I think we should follow suit. This patch was developed by grepping for “e500”, “__SPE__”, and “__NO_FPRS__”, and may not eliminate every vestige of SPE support. Most uses of __NO_FPRS__ are left alone, as they are relevant to normal embedded PowerPC with soft-float. * sysdeps/powerpc/preconfigure: Error out on powerpc-*-*gnuspe* host type. * scripts/build-many-glibcs.py: Remove powerpc-*-linux-gnuspe and powerpc-*-linux-gnuspe-e500v1 from list of build configurations. * sysdeps/powerpc/powerpc32/e500: Recursively delete. * sysdeps/unix/sysv/linux/powerpc/powerpc32/e500: Recursively delete. * sysdeps/unix/sysv/linux/powerpc/powerpc32/nofpu/context-e500.h: Delete. * sysdeps/powerpc/fpu_control.h: Remove SPE variant.

* Revert "Use Linux 5.1 in build-many-glibcs.py."Joseph Myers2019-05-071-1/+1
| | | | | | | | | This reverts commit c2b11710fb4a2e8d337ae8f042724143c5ccf173. Linux 5.1 headers are not in fact usable for glibc testing, because "[PATCH] uapi: avoid namespace conflict in linux/posix_types.h" <https://lore.kernel.org/lkml/20190319165123.3967889-1-arnd@arndb.de/> did not get merged for 5.1 and so many conform/ tests fail.

| | | | | | | | | | A few of our installed headers contain UTF-8 in comments. check-obsolete-constructs opened files without explicitly specifying their encoding, so it would barf on these headers if “make check” was run in a non-UTF-8 locale. * scripts/check-obsolete-constructs.py (HeaderChecker.check): Specify encoding="utf-8" when opening headers to check.
* Use Linux 5.0 in build-many-glibcs.py.Joseph Myers2019-03-131-3/+4
| | | | | | | | | | | | | | | | | This patch makes build-many-glibcs.py use Linux 5.0 in place of 4.20 (now that the test change required to avoid false positives with ulong in kernel headers has been committed). This includes adjusting the logic to compute a tarball URL to handle different major version numbers (rather than changing the path to hardcode v5.x in place of v4.x, as someone might still wish to check out a v4.x version). Tested that build-many-glibcs.py successfully checks out Linux 5.0 sources after this patch. * scripts/build-many-glibcs.py (Context.checkout): Default Linux version to 5.0. (Context.checkout_tar): Handle variable major version for Linux kernel.
* Use a proper C tokenizer to implement the obsolete typedefs test.Zack Weinberg2019-03-132-32/+471
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The test for obsolete typedefs in installed headers was implemented using grep, and could therefore get false positives on e.g. “ulong” in a comment. It was also scanning all of the headers included by our headers, and therefore testing headers we don’t control, e.g. Linux kernel headers. This patch splits the obsolete-typedef test from scripts/check-installed-headers.sh to a separate program, scripts/check-obsolete-constructs.py. Being implemented in Python, it is feasible to make it tokenize C accurately enough to avoid false positives on the contents of comments and strings. It also only examines $(headers) in each subdirectory--all the headers we install, but not any external dependencies of those headers. Headers whose installed name starts with finclude/ are ignored, on the assumption that they contain Fortran. It is also feasible to make the new test understand the difference between _defining_ the obsolete typedefs and _using_ the obsolete typedefs, which means posix/{bits,sys}/types.h no longer need to be exempted. This uncovered an actual bug in bits/types.h: __quad_t and __u_quad_t were being used to define __S64_TYPE, __U64_TYPE, __SQUAD_TYPE and __UQUAD_TYPE. These are changed to __int64_t and __uint64_t respectively. This is a safe change, despite the comments in bits/types.h claiming a difference between __quad_t and __int64_t, because those comments are incorrect. In all current ABIs, both __quad_t and __int64_t are ‘long’ when ‘long’ is a 64-bit type, and ‘long long’ when ‘long’ is a 32-bit type, and similarly for __u_quad_t and __uint64_t. (Changing the types to be what the comments say they are would be an ABI break, as it affects C++ name mangling.) This patch includes a minimal change to make the comments not completely wrong. sys/types.h was defining the legacy BSD u_intN_t typedefs using a construct that was not necessarily consistent with how the C99 uintN_t typedefs are defined, and is also too complicated for the new script to understand (it lexes C relatively accurately, but it does not attempt to expand preprocessor macros, nor does it do any actual parsing). This patch cuts all of that out and uses bits/types.h's __uintN_t typedefs to define u_intN_t instead. This is verified to not change the ABI on any supported architecture, via the c++-types test, which means u_intN_t and uintN_t were, in fact, consistent on all supported architectures.

* check-wrapper-headers test: Adjust Fortran include file directoryFlorian Weimer2019-03-071-1/+1
| | | | | | | The check for "/finclude/" fails with the actual location of Fortran headers because they are now stored in the "finclude" subdirectory of the top-level include directory, so a relative path does not contain a slash '/' before the "finclude" string.

* Add check for missing wrapper headersFlorian Weimer2019-02-161-0/+113
| | | | | | | | | | | | | | | If building on a subset of architectures only, it is easy to miss wrapper headers which are required by other architectures because they lack the corresponding sysdeps header. The check ensures that every installed header which is not itself a sysdeps header has a header under include/ (that presumably wraps the header, and perhaps also adding declarations and definitions for !_ISOMAC). Also check for the absence of the sysdeps/generic/bits directory removed in commit c72565e5f1124c2dc72573e83406fe999e56091f, to make accidental re-introduction more difficult.

* Add test that MAP_* constants agree with kernel.Joseph Myers2018-12-171-4/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Continuing the process of building up and using Python infrastructure for extracting and using values in headers, this patch adds a test that MAP_* constants from sys/mman.h agree with those in the Linux kernel headers. (Other sys/mman.h constants could be added to the test separately.) This set of constants has grown over time, so the generic code is enhanced to allow saying extra constants are OK on either side of the comparison (where the caller sets those parameters based on the Linux kernel headers version, compared with the version the headers were last updated from). Although the test is a custom Python file, my intention is to move in future to a single Python script for such tests and text files it takes as inputs, once there are enough examples to provide a guide to the common cases in such tests (I'd like to end up with most or all such sets of constants copied from kernel headers having such tests, and likewise for structure layouts from the kernel). The Makefile code is essentially the same as for tst-signal-numbers, but I didn't try to find an object file to depend on to represent the dependency on the headers used by the test (the conform/ tests don't try to represent such header dependencies at all, for example). Tested with build-many-glibcs.py, and also for x86_64 with older kernel headers. * scripts/glibcextract.py (compare_macro_consts): Take parameters to allow extra macros from first or second sources. * sysdeps/unix/sysv/linux/tst-mman-consts.py: New file. * sysdeps/unix/sysv/linux/Makefile [$(subdir) = misc] (tests-special): Add $(objpfx)tst-mman-consts.out.

* Use gen-as-const.py to process .pysym files.Joseph Myers2018-12-102-118/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch eliminates the gen-py-const.awk variant of gen-as-const, switching to use of gnu-as-const.py (with a new --python option) to process .pysym files (i.e., to generate nptl_lock_constants.py), as the syntax of those files is identical to that of .sym files. Note that the generated nptl_lock_constants.py is *not* identical to the version generated by the awk script. Apart from the trivial changes (comment referencing the new script, and output being sorted), the constant FUTEX_WAITERS, PTHREAD_MUTEXATTR_FLAG_BITS, PTHREAD_MUTEXATTR_FLAG_PSHARED and PTHREAD_MUTEX_PRIO_CEILING_MASK are now output as positive rather than negative constants (on x86_64 anyway; maybe not necessarily on 32-bit systems): < FUTEX_WAITERS = -2147483648 --- > FUTEX_WAITERS = 2147483648 < PTHREAD_MUTEXATTR_FLAG_BITS = -251662336 < PTHREAD_MUTEXATTR_FLAG_PSHARED = -2147483648 --- > PTHREAD_MUTEXATTR_FLAG_BITS = 4043304960 > PTHREAD_MUTEXATTR_FLAG_PSHARED = 2147483648 < PTHREAD_MUTEX_PRIO_CEILING_MASK = -524288 --- > PTHREAD_MUTEX_PRIO_CEILING_MASK = 4294443008 This is because gen-as-const has a cast of the constant value to long int, which gen-py-const lacks. I think the positive values are more logically correct, since the constants in question are in fact unsigned in C. But to reliably produce gen-as-const.py output for constants that always (in C and Python) reflects the signedness of values with the high bit of "long int" set would mean more complicated logic needs to be used in computing values. The more correct positive values by themselves produce a failure of nptl/test-mutexattr-printers, because masking with ~PTHREAD_MUTEXATTR_FLAG_BITS & ~PTHREAD_MUTEX_NO_ELISION_NP now leaves a bit -1 << 32 in the Python value, resulting in a KeyError exception. To avoid that, places masking with ~ of one of the constants in question are changed to mask with 0xffffffff as well (this reflects how ~ in Python applies to an infinite-precision integer whereas ~ in C does not do any promotions beyond the width of int). Tested for x86_64. * scripts/gen-as-const.py (main): Handle --python option. * scripts/gen-py-const.awk: Remove. * Makerules (py-const-script): Use gen-as-const.py. ($(py-const)): Likewise. * nptl/nptl-printers.py (MutexPrinter.read_status_no_robust): Mask with 0xffffffff together with ~(PTHREAD_MUTEX_PRIO_CEILING_MASK).

* Move tst-signal-numbers to Python.Joseph Myers2018-12-102-57/+165
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch converts the tst-signal-numbers test from shell + awk to Python. As with gen-as-const, the point is not so much that shell and awk are problematic for this code, as that it's useful to build up general infrastructure in Python for use of a range of code involving extracting values from C headers. This patch moves some code from gen-as-const.py to a new glibcextract.py, which also gains functions relating to listing macros, and comparing the values of a set of macros from compiling two different pieces of code. It's not just signal numbers that should have such tests; pretty much any case where glibc copies constants from Linux kernel headers should have such tests that the values and sets of constants agree except where differences are known to be OK. Much the same also applies to structure layouts (although testing those without hardcoding lists of fields to test will be more complicated). Given this patch, another test for a set of macros would essentially be just a call to glibcextract.compare_macro_consts (plus boilerplate code - and we could move to having separate text files defining such tests, like the .sym inputs to gen-as-const, so that only a single Python script is needed for most such tests). Some such tests would of course need new features, e.g. where the set of macros changes in new kernel versions (so you need to allow new macro names on the kernel side if the kernel headers are newer than the version known to glibc, and extra macros on the glibc side if the kernel headers are older). tst-syscall-list.sh could become a Python script that uses common code to generate lists of macros but does other things with its own custom logic. There are a few differences from the existing shell + awk test. Because the new test evaluates constants using the compiler, no special handling is needed any more for one signal name being defined to another. Because asm/signal.h now needs to pass through the compiler, not just the preprocessor, stddef.h is included as well (given the asm/signal.h issue that it requires an externally provided definition of size_t). The previous code defined __ASSEMBLER__ with asm/signal.h; this is removed (__ASSEMBLY__, a different macro, eliminates the requirement for stddef.h on some but not all architectures). Tested for x86_64, and with build-many-glibcs.py. * scripts/glibcextract.py: New file. * scripts/gen-as-const.py: Do not import os.path, re, subprocess or tempfile. Import glibcexctract. (compute_c_consts): Remove. Moved to glibcextract.py. (gen_test): Update reference to compute_c_consts.

* Make gen-as-const.py handle '--' consistently with awk script.Joseph Myers2018-12-031-29/+35
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It was reported in <https://sourceware.org/ml/libc-alpha/2018-12/msg00045.html> that gen-as-const.py fails to generate test code in the case where a .sym file has no symbols in it, so resulting in a test failing to link for Hurd. The relevant difference from the old awk script is that the old script treated '--' lines as indicating that the text to do at the start of the test (or file used to compute constants) should be output at that point if not already output, as well as treating lines with actual entries for constants like that. This patch changes gen-as-const.py accordingly, making it the sole responsibility of the code parsing .sym files to determine when such text should be output and ensuring it's always output at some point even if there are no symbols and no '--' lines, since not outputting it means the test fails to link. Handling '--' like that also avoids any problems that would arise if the first entry for a symbol were inside #ifdef (since the text in question must not be output inside #ifdef). Tested for x86_64, and with build-many-glibcs.py for i686-gnu. Note that there are still compilation test failures for i686-gnu (linknamespace tests, possibly arising from recent posix_spawn-related changes). * scripts/gen-as-const.py (compute_c_consts): Take an argument 'START' to indicate that start text should be output. (gen_test): Likewise. (main): Generate 'START' for first symbol or '--' line, or at end of input if not previously generated.

* Replace gen-as-const.awk by gen-as-const.py.Joseph Myers2018-11-302-63/+159
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch replaces gen-as-const.awk, and some fragments of the Makefile code that used it, by a Python script. The point is not such much that awk is problematic for this particular script, as that I'd like to build up a general Python infrastructure for extracting information from C headers, for use in writing tests of such headers. Thus, although this patch does not set up such infrastructure, the compute_c_consts function in gen-as-const.py might be moved to a separate Python module in a subsequent patch as a starting point for such infrastructure. The general idea of the code is the same as in the awk version, but no attempt is made to make the output files textually identical. When generating a header, a dict of constant names and values is generated internally then defines are printed in sorted order (rather than the order in the .sym file, which would have been used before). When generating a test that the values computed match those from a normal header inclusion, the test code is made into a compilation test using _Static_assert, where previously the comparisons were done only when the test was executed. One fragment of test generation (converting the previously generated header to use asconst_* prefixes on its macro names) is still in awk code in the makefiles; only the .sym processing and subsequent execution of the compiler to extract constants have moved to the Python script. Tested for x86_64, and with build-many-glibcs.py. * scripts/gen-as-const.py: New file. * scripts/gen-as-const.awk: Remove. * Makerules ($(common-objpfx)%.h $(common-objpfx)%.h.d): Use gen-as-const.py.

* Do not copy glibc sources in build-many-glibcs.py.Joseph Myers2018-11-281-21/+1
| | | | | | | | | | | | | | | | | | | | | | | | Now that build-many-glibcs.py touches at checkout time all files that might get rebuilt in the glibc source directory in a normal glibc build and test run, this patch stops the script from copying the glibc source directory, so that all builds use the original directory directly (and less disk space is used, less I/O is involved and cached copies of the sources in memory can be shared between all the builds - as well as avoiding spurious failures from copying while "git gc" is running). This is similar to how all other components were already handled. Any bugs involving writing into the source directory can be dealt with in future as normal bugs, just as such bugs already are handled. Tested with build-many-glibcs.py runs with a read-only glibc source directory, with all files not touched by the script having timestamps in forwards alphabetical order and separately with all files not touched by the script having timestamps in backwards alphabetical order. * scripts/build-many-glibcs.py (Glibc.build_glibc): Use original source directory instead of a copy. (CommandList.create_copy_dir): Remove.
* abilist.awk: Treat .tdata like .tbss and reject unknown combinations.Carlos O'Donell2018-11-261-9/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | Mathieu Desnoyers ran into an issue with his rseq patch where he was the first person to add weak thread-local data and this resulted in an ABI list update with entries like this: "GLIBC_2.29 w ? D .tdata 0000000000000020". The weakness of the symbol has nothing to do with the DSOs ABI and so we should not write anything about weak symbols here. The .tdata entries should be treated exactly like .tbss entries and the output should have been: "GLIBC_2.29 __rseq_abi T 0x20" This change makes abilist.awk handle .tdata just like .tbss, while at the same time adding an error case for the default, and the unknown line cases. We never want anyone to be able to add such entries to any ABI list files and should see an immediate error and consult with experts. Tested by Mathieu Desnoyers <mathieu.desnoyers@efficios.com> with the rseq patch set and 'make update-all-abi'. Tested myself with 'make update-all-abi' on x86_64 with no changes.

* Touch more glibc source files in build-many-glibcs.py.Joseph Myers2018-11-261-0/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | build-many-glibcs.py currently copies the source tree to avoid issues with parallel builds trying to write into it. This copying can result in occasional spurious build failures from bots, when a "git gc" is in progress that changes .git contents while copying is taking place, and it would also be desirable to avoid the need to copy to save on disk space, I/O and memory used in build-many-glibcs.py builds. In preparation for removing the copying, this patch arranges for build-many-glibcs.py to touch more files on checkout so their timestamps do not result in make attempting to rebuild them. Before actually removing the copying, I intend to do further tests to ensure I haven't missed any other such makefile dependencies. This is of course without prejudice to possibly moving more of these files to being generated in the build directory rather than being checked in at all, where that can be done using build tools already required for the build. For sysdeps files (installed and otherwise) it would be necessary to make sure this does not affect the search ordering, for headers used in the build it would be necessary to ensure they are generated early enough, and for errlist.c there may be dual licensing reasons for keeping it checked in. Tested that a checkout with build-many-glibcs.py does touch the expected files and that a glibcs build for aarch64-linux-gnu succeeds. * scripts/build-many-glibcs.py (Context.fix_glibc_timestamps): Touch additional files.

* Remove pre-Python-3.4 compatibility from build-many-glibcs.py.Joseph Myers2018-10-261-11/+0
| | | | | | | | | | | | | | | | | | | Since we have consensus on requiring Python 3.4 or later to build glibc, it follows that compatibility with older Python versions is also no longer relevant to auxiliary Python scripts for use in glibc development. This patch removes such compatibility code from build-many-glibcs.py (compatibility code needed for 3.4, which lacks the newer subprocess interface, is kept). Because build-many-glibcs.py is not itself called from the glibc build system, this patch is independent of the configure checks for having a new-enough Python version, which are only relevant to uses of Python from the main build and test process. Tested with build-many-glibcs.py building glibc for aarch64-linux-gnu (with Python 3.4 to make sure that still works). * scripts/build-many-glibcs.py: Remove compatibility for missing os.cpu_count and re.fullmatch.

* Add build-many-glibcs.py support for building more GCC libraries.Joseph Myers2018-09-111-12/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Every so often we get libsanitizer or libgo builds breaking with new glibc because of some change in the glibc headers. glibc's build-many-glibcs.py deliberately disables libsanitizer and GCC languages other than C and C++ because the point is to test glibc and find glibc problems (including problems shown up by new compiler warnings in new GCC), not to test libsanitizer or libgo; if the compiler build fails because of libsanitizer or libgo failing to build, that could hide the existence of new problems in glibc. However, it seems reasonable to have a non-default mode where build-many-glibcs.py does build those additional pieces, which this patch adds. Note that I do not intend to run a build-many-glibcs.py bot with this new option. If people concerned with libsanitizer, libgo or other potentially affected GCC libraries wish to find out about such problems more quickly, they may wish to run such a bot or bots (and to monitor the results and fix issues found - obviously there will be some overlap with issues found by my bots not using that option). Note also that building a non-native Ada compiler requires a sufficiently recent native (or build-x-host, in general) Ada compiler to be used, possibly more or less the same version as being built. That needs to be in the PATH when build-many-glibcs.py --full-gcc is run; the script does not deal with setting up such a compiler (or any of the other host tools needed for building GCC and glibc, beyond the GMP / MPFR / MPC libraries), but perhaps it should, to avoid the need to keep updating such a compiler manually when running a bot. Tested by running build-many-glibcs.py with the new option, with mainline GCC. There are build failures for various configurations, which may be of interest to Go / Ada people even if you're not interested in running such a bot: * mips64 / mips64el (all configuration): ICE building libstdc++, as seen without using the new option <https://gcc.gnu.org/bugzilla/show_bug.cgi?id=87156>. * aarch64_be: error building libgo (little-endian aarch64 works fine): version.go:67:13: error: expected ';' or ')' or newline 67 | BigEndian = | ^ version.go:67:3: error: reference to undefined name 'BigEndian' 67 | BigEndian = | ^ * arm (all configurations): error building libgo: /scratch/jmyers/glibc/many9/src/gcc/libgo/go/internal/syscall/unix/getrandom_linux.go:29:5: error: reference to undefined name 'randomTrap' 29 | if randomTrap == 0 { | ^ /scratch/jmyers/glibc/many9/src/gcc/libgo/go/internal/syscall/unix/getrandom_linux.go:38:34: error: reference to undefined name 'randomTrap' 38 | r1, _, errno := syscall.Syscall(randomTrap, | ^ What's happening there is, I think, that the arm*b*-*-* case in libgo/configure.ac is wrongly matching arm-glibc-linux-gnueabi with the 'b' in the vendor part, and then something else is failing to handle GOARCH=armbe.

I've filed <https://gcc.gnu.org/bugzilla/show_bug.cgi?id=87281> for this. * m68k: ICE in the Go front end building libgo <https://gcc.gnu.org/bugzilla/show_bug.cgi?id=84948>. * microblaze, microblazeel, nios2, sh3, sh3eb: build failure in libada for lack of a libada port to those systems (I'm not sure sh3 would actually need anything different from sh4): a-cbdlli.ads:38:14: violation of restriction "No_Finalization" at system.ads:47 * i686-gnu: build failure in libada, might be fixed by the patch attached to <https://gcc.gnu.org/bugzilla/show_bug.cgi?id=81103> (not tested): terminals.c:1115:13: fatal error: termio.h: No such file or directory * scripts/build-many-glibcs.py (Context.__init__): Add full_gcc argument. (Config.build_gcc): Use --disable-libsanitizer for first GCC build, but not for second build if --full-gcc. Use --enable-languages=all for second build if --full-gcc. (get_parser): Add --full-gcc option. (main): Update call to Context.
