* Use Linux 5.6 and GMP 6.2.0 in build-many-glibcs.py.Joseph Myers2020-03-311-2/+2
| | | | | | | | This patch makes build-many-glibcs.py use the current versions of Linux (5.6) and GMP (6.2.0). Tested with build-many-glibcs.py (host-libraries, compilers and glibcs builds).
* build-many-glibcs.py: Add list-compilers, list-glibcs commandsFlorian Weimer2020-03-031-4/+21
| | | | | These commands are helpful for scripting the distribution of build-many-glibcs.py runs across multiple builders.
* build-many-glibcs.py: Add --shallow optionFlorian Weimer2020-03-031-3/+12
| | | | | | | | The history is not used by build-many-glibcs.py itself. --replace-sources deletes an existing source tree before switching the version. But some users prefer to have the full history available, therefore make shallow clones optional with the --shallow option.
* Use --disable-gdbserver in build-many-glibcs.py.Joseph Myers2020-02-101-0/+1
| | | | | | | | | | | | | Now that binutils-gdb has gdbserver at top level, an extra --disable-gdbserver configure option is needed when configuring binutils from a git checkout to avoid it also building gdbserver unnecessarily (although fairly harmlessly). This patch updates the options used in build-many-glibcs.py accordingly (although this might end up not being needed depending on what happens regarding whether gdbserver gets built for host != target). Tested with a build-many-glibcs.py compilers build for aarch64-linux-gnu using binutils-gdb master.
* Use binutils 2.34 branch in build-many-glibcs.py.Joseph Myers2020-02-031-1/+1
| | | | | | This patch makes build-many-glibcs.py use binutils 2.34 branch. Tested with build-many-glibcs.py (compilers and glibcs builds).
* Use Linux 5.5 in build-many-glibcs.py.Joseph Myers2020-02-031-1/+1
| | | | | | This patch makes build-many-glibcs.py use Linux 5.5. Tested with build-many-glibcs.py (compilers and glibcs builds).
* Update build-many-glibcs.py for GCC move to git.Joseph Myers2020-01-131-10/+17
| | | | | | | This patch updates build-many-glibcs.py for the move of GCC to git, teaching it to do the initial checkout from git, to replace an SVN checkout with a git one if --replace-sources is used, and to get the commit identifier from a git checkout after updating it.
* build-many-glibcs.py: Fix “glibcs i686-gnu --strip”Florian Weimer2020-01-021-4/+9
| | | | | | Hurd uses an empty prefix, so the linker scripts end up in /lib, the find command picked them up, and stripping them failed because they are not ELF files.
* build-many-glibcs.py: Implement update-syscalls commandFlorian Weimer2020-01-021-3/+62
| | | | | | | | | This command uses pre-built compilers to re-install the Linux headers from the current sources into a temporary location and runs glibc's “make update-syscalls-lists” against that. This updates the glibc source tree with the current system call numbers. Reviewed-by: Siddhesh Poyarekar <siddhesh@sourceware.org>
* build-many-glibcs.py: Introduce glibc build policy classesFlorian Weimer2020-01-021-49/+80

* 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

* 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.

* 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.

| | | | | | | | | 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.

* 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.

* 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.
* 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. Given that you can have configurations with multilibs of both endiannesses, endianness should always be detected by configure.ac, for all architectures, using a compile test of whether __BYTE_ORDER__ == __ORDER_BIG_ENDIAN__, not based on textual matches to the host (= target at top-level) triplet. * armeb (all configurations): error building libada (for some reason the Arm libada configuration seems to do different things for EH for big-endian, which makes no sense to me and doesn't actually work): a-exexpr.adb:87:06: "System.Exceptions.Machine" is not a predefined library unit a-exexpr.adb:87:06: "Ada.Exceptions (body)" depends on "Ada.Exceptions.Exception_Propagation (body)" a-exexpr.adb:87:06: "Ada.Exceptions.Exception_Propagation (body)" depends on "System.Exceptions.Machine (spec)" * hppa: error building libgo (same error as for aarch64_be). * ia64: ICE building libgo.

(get_parser): Add --full-gcc option. (main): Update call to Context.
* Add build-many-glibcs.py --enable-obsolete-* configs.Joseph Myers2018-09-101-0/+8
| | | | | | | | | | | | | | | We've had issues before with build failures (with new GCC) in code only built with --enable-obsolete-rpc or --enable-obsolete-nsl not being reported for a while because build-many-glibcs.py does not test those configure options. This patch adds configurations (32-bit and 64-bit) using those options so that in future we can notice quickly if they start failing to build. Tested the new configurations do build with GCC 8. * scripts/build-many-glibcs.py (Context.add_all_configs): Add x86_64 and i686 configs using --enable-obsolete-rpc --enable-obsolete-nsl.
* Use Linux 4.18 in build-many-glibcs.py.Joseph Myers2018-08-131-1/+1
| | | | | * scripts/build-many-glibcs.py (Context.checkout): Default Linux version to 4.18.
* Use binutils 2.31 branch in build-many-glibcs.py.Joseph Myers2018-07-201-1/+1
| | | | | * scripts/build-many-glibcs.py (Context.checkout): Default binutils version to 2.31 branch.
* Change URL of gcc's tarballZong Li2018-07-201-1/+1
| | | | | | | After 7.1.0 version, there is no .bz2 format of gcc's tarball. * scripts/build-many-glibcs.py (Context.checkout_tar): Change the URL of gcc's tarball.
* Use Linux 4.17 in build-many-glibcs.py.Joseph Myers2018-06-041-1/+1
| | | | | * scripts/build-many-glibcs.py (Context.checkout): Default Linux version to 4.17
* Remove tilegx port.Joseph Myers2018-04-271-9/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since tile support has been removed from the Linux kernel for 4.17, this patch removes the (unmaintained) port to tilegx from glibc (the tilepro support having been previously removed). This reflects the general principle that a glibc port needs upstream support for the architecture in all the components it build-depends on (so binutils, GCC and the Linux kernel, for the normal case of a port supporting the Linux kernel but no other OS), in order to be maintainable. Apart from removal of sysdeps/tile and sysdeps/unix/sysv/linux/tile, there are updates to various comments referencing tile for which removal of those references seemed appropriate. The configuration is removed from README and from build-many-glibcs.py. contrib.texi keeps mention of removed contributions, but I updated Chris Metcalf's entry to reflect that he also contributed the non-removed support for the generic Linux kernel syscall interface. __ASSUME_FADVISE64_64_NO_ALIGN support is removed, as it was only used by tile. * sysdeps/tile: Remove. * sysdeps/unix/sysv/linux/tile: Likewise. * README (tilegx-*-linux-gnu): Remove from list of supported configurations. * manual/contrib.texi (Contributors): Mention Chris Metcalf's contribution of support for generic Linux kernel syscall interface. * scripts/build-many-glibcs.py (Context.add_all_configs): Remove tilegx configurations. (Config.install_linux_headers): Do not handle tile. * sysdeps/unix/sysv/linux/aarch64/ldsodefs.h: Do not mention Tile in comment. * sysdeps/unix/sysv/linux/nios2/Makefile: Likewise. * sysdeps/unix/sysv/linux/posix_fadvise.c: Likewise. [__ASSUME_FADVISE64_64_NO_ALIGN] (__ALIGNMENT_ARG): Remove conditional undefine and redefine. * sysdeps/unix/sysv/linux/posix_fadvise64.c: Do not mention Tile in comment. [__ASSUME_FADVISE64_64_NO_ALIGN] (__ALIGNMENT_ARG): Remove conditional undefine and redefine.
* Use GCC 8 in build-many-glibcs.py by default.Joseph Myers2018-04-251-1/+1
| | | | | | | | | | | | | | | | | Now that GCC 8 has branched, this patch makes build-many-glibcs.py default to using GCC 8 branch instead of GCC 7. The effect should be that all builds complete cleanly and the compilation parts of the glibc testsuite complete cleanly except for on i686-gnu (with GCC 7 there were testsuite failures for some other configurations as well). I've replaced my bot building using GCC 6 branch with one using GCC 8 branch. (Of course glibc should continue building with GCC 6 - and for that matter GCC 5 and 4.9, which are no longer maintained, are supported versions as well - but building with GCC 6 will no longer be included in my bot testing.) * scripts/build-many-glibcs.py (Context.checkout): Default GCC version to GCC 8 branch.
* Make build-many-glibcs.py build GCC for powerpcspe with --enable-obsolete.Joseph Myers2018-04-181-2/+3
| | | | | | | | | | | | | | | The powerpcspe GCC port has been obsoleted in GCC 8 for not having had the removal of code for non-SPE processors completed. This patch accordingly arranges for build-many-glibcs.py to configure GCC with --enable-obsolete for affected configurations. This is temporary; either the port gets cleaned up and unobsoleted in GCC and the configure option can be removed, or the port gets removed in GCC and we should remove the corresponding glibc support. Tested with build-many-glibcs.py for the affected configurations. * scripts/build-many-glibcs.py (Context.add_all_configs): Use --enable-obsolete for powerpc-linux-gnuspe.
* Use Linux 4.16 in build-many-glibcs.py.Joseph Myers2018-04-031-1/+1
| | | | | * scripts/build-many-glibcs.py (Context.checkout): Default Linux version to 4.16.
* Use MPFR 4.0.1 in build-many-glibcs.py.Joseph Myers2018-02-071-1/+1
| | | | | * scripts/build-many-glibcs.py (Context.checkout): Default MPFR version to 4.0.1.
