* 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. 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. 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.
* 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 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.
* check-execstack: Permit sysdeps to xfail some libsSamuel Thibault2018-07-201-5/+22
| | | | | | | | | | | * scripts/check-execstack.awk: Consider `xfail' variable containing a list of libraries whose stack executability is expected. * elf/Makefile ($(objpfx)check-execstack.out): Pass $(check-execstack-xfail) to check-execstack.awk through `xfail' variable. * sysdeps/mach/hurd/i386/Makefile (check-execstack-xfail): Set to ld.so libc.so libpthread.so.
* Fix hardcoded /tmp paths in testing (bug 13888).Joseph Myers2018-06-261-6/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As noted in bug 13888, and as I noted previously in <https://sourceware.org/ml/libc-alpha/2000-10/msg00111.html>, various tests used hardcoded paths in /tmp, so posing issues for simultaneous test runs from different build directories. This patch fixes such uses of hardcoded file names to put them in the build directory instead (in the case of stdio-common/bug5 the file names are changed as well, to avoid a conflict with the name bug5.out also used for the automatic test output redirection). It also fixes test-installation.pl likewise (that was using filenames with $$ in them rather than strictly hardcoded names, but that's still not good practice for temporary file naming). Note that my list of files changed is not identical to that in bug 13888. I added tst-spawn3.c and test-installation.pl, and removed some tests that seem to me (now) to create temporary files securely (simply using /tmp is not itself a problem if the temporary files are handled properly with mkstemp; I haven't checked whether those tests used to do things insecurely). conformtest is not changed because the makefiles always pass a --tmpdir option so the /tmp default is irrelevant, and for the same reason there is no actual problem with nptl/tst-umask1.c because again the makefiles always override the default. nptl/sockperf.c is ignored because there is no code to run it; probably that file should actually be removed. Some tests use the mktemp function, but I think they all use it in a way that *is* secure (for generating names for directories / sockets / fifos / symlinks, where the operation using the name will not follow symlinks and so there is no potential for a symlink attack on the account running the testsuite). Some tests use the tmpnam function to generate temporary file names. This is in principle insecure, but not addressed by this patch (I consider it a separate issue from the fully hardcoded paths). Tested for x86_64. [BZ #13888] * posix/Makefile (CFLAGS-tst-spawn3.c): New variable. * posix/tst-spawn3.c (do_test): Put tst-spwan3.pid in OBJPFX, not /tmp. * scripts/test-installation.pl: Put temporary files in build directory, not /tmp. * stdio-common/Makefile (CFLAGS-bug3.c): New variable.

* scripts/update-abilist.sh: Accept empty list of files to patchFlorian Weimer2018-06-141-1/+4
| | | | | | Commit b289cd9db8286fa6c670104dd5dfcfc68d5d00d6 (“Ignore absolute symbols in ABI tests.”) broke “make update-all-abi” because an empty list of files is now passed to scripts/update-abilist.sh.
* Mark _init and _fini as hidden [BZ #23145]H.J. Lu2018-06-081-0/+63
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | _init and _fini are special functions provided by glibc for linker to define DT_INIT and DT_FINI in executable and shared library.

With older binutils, it is included for MIPS o32 (despite the use of symbol versioning), and this means that all the ABI test baselines for MIPS o32 include "_gp_disp _gp_disp A". This symbol is not meaningfully part of the ABI for shared libraries, since it always has to be resolved at static link time to the local definition for the linked object. All the other absolute symbols in ABI test baselines are the names of symbol versions. I don't think the mere existence of a symbol version with a given name - as opposed to the contents of that version if nonempty - is part of the ABI either. Thus, this patch allows the ABI tests to pass both before and after the binutils change by changing abilist.awk not to include absolute symbols in its output, and changing the baselines accordingly.

* 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.

* 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.
* Disable lock elision for mutex pretty printer tests.Stefan Liebler2018-04-191-0/+3
| | | | | | | | | | | | | | | | | | | | | If e.g. the testcase nptl/test-mutex-printers is run with enabled lock-elision, it fails on s390x with: Error: Response does not match the expected pattern. Command: print *mutex Expected pattern: pthread_mutex_t Response: No symbol "mutex" in current context. (gdb) See https://www.sourceware.org/ml/libc-alpha/2018-03/msg00583.html for more details. In fact the mutex pretty printer tests rely on looking at the internal details of the lock, thus we disable it by setting up the GLIB_TUNABLES environment variable inside gdb. ChangeLog: * scripts/test_printers_common.py (init_test): Disable lock elision.
* 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.

* Don't install libio.h or _G_config.h.Zack Weinberg2018-02-071-5/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We shipped 2.27 with libio.h and _G_config.h still installed but issuing warnings when used. Let's stop installing them early in 2.28 so that we have plenty of time to think of another plan if there are problems. The public stdio.h had a genuine dependency on libio.h for the complete definitions of FILE and cookie_io_functions_t, and a genuine dependency on _G_config.h for the complete definitions of fpos_t and fpos64_t; these are moved to single-type headers. bits/types/struct_FILE.h also provides a handful of accessor and bitflags macros so that code is not duplicated between bits/stdio.h and libio.h. All the other _IO_ and _G_ names used by the public stdio.h can be replaced with either public names or __-names. In order to minimize the risk of breaking our own compatibility code, bits/types/struct_FILE.h preserves the _IO_USE_OLD_IO_FILE mechanism exactly as it was in libio.h, but you have to define _LIBC to use it, or it'll error out. Similarly, _IO_lock_t_defined is preserved exactly, but will error out if used without defining _LIBC. Internally, include/stdio.h continues to include libio.h, and libio.h scrupulously provides every _IO_* and _G_* name that it always did, perhaps now defined in terms of the public names. This is how this patch avoids touching dozens of files throughout glibc and becoming entangled with the _IO_MTSAFE_IO mess. The remaining patches in this series eliminate most of the _G_ names. Tested on x86_64-linux; in addition to the test suite, I installed the library in a sysroot and verified that a simple program that uses stdio.h could be compiled against the installed library, and I also verified that installed stripped libraries are unchanged. * libio/bits/types/__fpos_t.h, libio/bits/types/__fpos64_t.h: New single-type headers split from _G_config.h. * libio/bits/types/cookie_io_functions_t.h * libio/bits/types/struct_FILE.h New single-type headers split from libio.h. * libio/Makefile: Install the above new headers. Don't install libio.h, _G_config.h, bits/libio.h, bits/_G_config.h, or bits/libio-ldbl.h. * libio/_G_config.h, libio/libio.h: Delete file. * libio/bits/libio.h: Remove improper-inclusion guard. Include stdio.h and don't repeat anything that it does.

Define _STDIO_USES_IOSTREAM, __HAVE_COLUMN, and _IO_file_flags here, in the "compatibility defines" section. Remove an #if 0 block. Use the "body" macros from bits/types/struct_FILE.h to define _IO_getc_unlocked, _IO_putc_unlocked, _IO_feof_unlocked, and _IO_ferror_unlocked. Move prototypes of __uflow and __overflow... * libio/stdio.h: ...here. Don't include bits/libio.h. Don't define _STDIO_USES_IOSTREAM. Get __gnuc_va_list directly from stdarg.h. Include bits/types/__fpos_t.h, bits/types/__fpos64_t.h, bits/types/struct_FILE.h, and, when __USE_GNU, bits/types/cookie_io_functions_t.h.

* Make build-many-glibcs.py clean git source directories.Joseph Myers2018-01-291-0/+3
| | | | | | | | | | | | | | | | | | With the git checkouts of Hurd components in build-many-glibcs.py involving running autoreconf, there's a risk that generated files could be left behind by an old autoreconf run (if an old version of the sources generates those files in the source directory but a new version does not). This patch avoids that by using git clean -dxfq when updating git checkouts. In this patch, that's conditional on --replace-sources, to avoid removing any local not-checked-in files someone may have in their checkout unless the option has been specifically passed that says it's OK to blow old checkouts away, complete with any local changes to them. * scripts/build-many-glibcs.py (Context.git_checkout): Use git clean -dxfq for git updates when replacing sources.
* Clean up build-many-glibcs.py libcilkrts disabling.Joseph Myers2018-01-291-3/+5
| | | | | | | | | | | | | | | | The disabling of libcilkrts in build-many-glibcs.py has some peculiarities. It's only for the final GCC build, not the initial bootstrap one, whereas normally anything disabled for the final build should be disabled for the bootstrap one as well. And it's only for Hurd, when it's more natural by analogy with the libsanitizer disabling to disable this library unconditionally, not only for targets where it's known to break. This patch cleans up that disabling accordingly, adding a comment so it's obvious it can be removed once GCC 7 is too old to build glibc. * scripts/build-many-glibcs.py (Config.build_gcc): Use --disable-libcilkrts unconditionally, not just for the final GCC build for Hurd.

(Note that the build for soft-float ColdFire is currently broken even with GCC mainline - I have a glibc patch to fix this, but it needs before-and-after build-many-glibcs.py comparison of stripped binaries for all configurations before being committed.) * scripts/build-many-glibcs.py (Context.add_all_configs): Add soft-float ColdFire configuration.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | libio.h was originally the header for a set of supported GNU extensions, but they have not been maintained as such in many years, they are now standing in the way of improvements to stdio, and we don't think there are any remaining external users. _G_config.h was never intended for public use, but predates the bits convention. Move both of these headers into the bits directory and provide stubs at top level which issue deprecation warnings.

* Fix build-many-glibcs.py arm-linux-gnueabihf builds with mainline GCC.Joseph Myers2017-12-191-5/+6
| | | | | | | | | | | | | | | | | My fix to make the arm-linux-gnueabihf build-many-glibcs.py builds actually use the hard-float ABI as intended showed up another issue when building with mainline GCC: GCC now determines an FPU based on the selected CPU or architecture and gives an error for -mfloat-abi=hard when the CPU does not imply a choice of FPU. This patch fixes all the affected configurations to specify a suitable --with-cpu, --with-fpu or -mfpu option explicitly to avoid that error from GCC. Tested the relevant configurations with build-many-glibcs.py with mainline GCC. * scripts/build-many-glibcs.py (Context.add_all_configs): Specify CPU or FPU for ARM hard-float configurations.
* Correct build-many-glibcs.py arm-linux-gnueabihf configurations.Joseph Myers2017-12-151-2/+4
| | | | | | | | | | | | | | The conventional configure triplet for ARM GNU/Linux with hard-float ABI is arm-*-linux-gnueabihf. However, GCC does not automatically use the hard-float ABI based on that triplet. This patch fixes build-many-glibcs.py to pass --with-float=hard so that the arm-linux-gnueabihf configurations actually build with the intended ABI. Tested building the affected configurations with build-many-glibcs.py. * scripts/build-many-glibcs.py (Context.add_all_configs): Use --with-float=hard for arm-linux-gnueabihf configurations.
* Remove --with-fp / --without-fp.Joseph Myers2017-12-121-34/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There is a configure option --without-fp that specifies that nofpu sysdeps directories should be used instead of fpu directories. For most glibc configurations, this option is of no use: either there is no valid nofpu variant of that configuration, or there are no fpu or nofpu sysdeps directories for that processor and so the option does nothing. For a few configurations, if you are using a soft-float compiler this option is required, and failing to use it generally results in compilation errors from inline asm using unavailable floating-point instructions. We're moving away from --with-cpu to configuring glibc based on how the compiler generates code, and it is natural to do so for --without-fp as well; in most cases the soft-float and hard-float ABIs are incompatible so you have no hope of building a working glibc with an inappropriately configured compiler or libgcc. This patch eliminates --without-fp, replacing it entirely by automatic configuration based on the compiler. Configurations for which this is relevant (coldfire / mips / powerpc32 / sh) define a variable with_fp_cond in their preconfigure fragments (under the same conditions under which those fragments do anything); this is a preprocessor conditional which the toplevel configure script then uses in a test to determine which sysdeps directories to use. The config.make with-fp variable remains. It's used only by powerpc (sysdeps/powerpc/powerpc32/Makefile) to add -mhard-float to various flags variables. For powerpc, -mcpu= options can imply use of soft-float. That could be an issue if you want to build for e.g. 476fp, but are using --with-cpu=476 because there isn't a 476fp sysdeps directory. If in future we eliminate --with-cpu and replace it entirely by testing the compiler, it would be natural at that point to eliminate that code as well (as the user should then just use a compiler defaulting to 476fp and the 476 sysdeps directory would be used automatically). Tested for x86_64, and tested with build-many-glibcs.py that installed shared libraries are unchanged by this patch. * configure.ac (--with-fp): Remove configure option. (with_fp_cond): New variable. (libc_cv_with_fp): New configure test.
