2018-01-29Make build-many-glibcs.py clean git source directories.Joseph Myers1-0/+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.
2018-01-29Clean up build-many-glibcs.py libcilkrts disabling.Joseph Myers1-3/+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.
2018-01-29Use Linux 4.15 in build-many-glibcs.py.Joseph Myers1-1/+1
This patch makes build-many-glibcs.py use Linux 4.15. Other glibc updates for Linux 4.15 can wait until after the 2.27 release. * scripts/build-many-glibcs.py (Context.checkout): Default Linux version to 4.15.
2018-01-28hurd: Make build-many-glibcs.py use mainline gnumachSamuel Thibault1-1/+8
Some warnings need a couple of fixes in the gnumach headers. * scripts/build-many-glibcs.py (checkout_vcs): Add gnumach repository URLs, run autoreconf, and make it the default for now.
2018-01-27hurd: make build-many-glibcs.py use mainline migSamuel Thibault1-1/+8
Some warnings come from code generated by mig, so we need a very recent version for now. * scripts/build-many-glibcs.py (checkout_vcs): Add mig repository URL, and run autoreconf, make it the default for now.
2018-01-27hurd: fix gcc build in build-many-glibcs.pySamuel Thibault1-0/+2
gcc's libcilkrts has never actually supported GNU/Hurd, and doesn't automatically disable it, and the support was actually removed in gcc trunk, so that will never actually be fixed there. * scripts/build-many-glibcs.py [os == gnu] (build_gcc): Pass --disable-libcilkrts to gcc configure.
2018-01-26hurd build-many-glibcs.py: use hurd mainline for nowSamuel Thibault1-1/+1

2018-01-24Add soft-float ColdFire to build-many-glibcs.py.Joseph Myers1-0/+5
Since it turns out soft-float ColdFire has a different glibc ABI to hard-float ColdFire, as well as various differences in which glibc code gets built, this patch adds such a configuration to build-many-glibcs.py to (hopefully) complete the set of ABIs being tested. (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.
2018-01-24Add build-many-glibcs.py support for Hurd.Joseph Myers1-10/+65
This patch adds build-many-glibcs.py support for GNU Hurd. Builds of the i686-gnu configuration will fail until sufficient support is merged to master, so completing build-many-glibcs.py coverage of all glibc ABIs and making results accurately reflect the broken state of builds for Hurd. * scripts/build-many-glibcs.py (Context.add_all_configs): Add i686-gnu configurations. (Context.run_builds): Include mig, gnumach and hurd in components considered. (Context.checkout): Add mig, gnumach and hurd to components. (Context.checkout_tar): Add URL mappings for mig, gnumach and hurd. (Context.bot_cycle): Check for changes to mig, gnumach and hurd. (Config.build): Install gnumach headers, build mig and install hurd headers for 'gnu' OS. (Config.install_gnumach_headers): New function. (Config.install_hurd_headers): Likewise. (Glibc.build_glibc): Do not use /usr for 'gnu' OS. Specifiy MIG when building for 'gnu' OS.
2018-01-15Update build-many-glibcs.py binutils, mpfr, mpc versions.Joseph Myers1-3/+3
* scripts/build-many-glibcs.py (Context.checkout): Default binutils version to 2.30 branch, MPFR version to 4.0.0 and MPC version to 1.1.0.
2018-01-06Strip shared objects in subdirectories of libPalmer Dabbelt1-1/+1
The RISC-V port will have libraries in subdirectories of lib, like "lib64/lp64d". This adds support for stripping these installed libraries. 2018-01-06 Palmer Dabbelt <palmer@sifive.com> * scripts/build-many-glibcs.py (class Glibc): Strip shared objects in subdirectories of lib.

2018-01-01Update copyright dates not handled by scripts/update-copyrights.Joseph Myers1-1/+1
I've updated copyright dates in glibc for 2018. This is the patch for the changes not generated by scripts/update-copyrights and subsequent build / regeneration of generated files. Please remember to include 2018 in the dates for any new files added in future (which means updating any existing uncommitted patches you have that add new files to use the new copyright dates in them). * NEWS: Update copyright dates. * catgets/gencat.c (print_version): Likewise. * csu/version.c (banner): Likewise. * debug/catchsegv.sh: Likewise. * debug/pcprofiledump.c (print_version): Likewise. * debug/xtrace.sh (do_version): Likewise. * elf/ldconfig.c (print_version): Likewise. * elf/ldd.bash.in: Likewise. * elf/pldd.c (print_version): Likewise. * elf/sotruss.sh: Likewise. * elf/sprof.c (print_version): Likewise. * iconv/iconv_prog.c (print_version): Likewise. * iconv/iconvconfig.c (print_version): Likewise. * locale/programs/locale.c (print_version): Likewise. * locale/programs/localedef.c (print_version): Likewise. * login/programs/pt_chown.c (print_version): Likewise. * malloc/memusage.sh (do_version): Likewise. * malloc/memusagestat.c (print_version): Likewise. * malloc/mtrace.pl: Likewise. * manual/libc.texinfo: Likewise. * nptl/version.c (banner): Likewise. * nscd/nscd.c (print_version): Likewise. * nss/getent.c (print_version): Likewise. * nss/makedb.c (print_version): Likewise. * posix/getconf.c (main): Likewise. * scripts/test-installation.pl: Likewise. * sysdeps/unix/sysv/linux/lddlibc4.c (main): Likewise.

2017-12-24Deprecate external use of libio.h and _G_config.h.Zack Weinberg1-0/+5
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. The contents of (bits/)libio.h and (bits/)_G_config.h are still exposed to external software via stdio.h; changing that requires more complex surgery than I have time to attempt right now. * libio/libio.h, libio/_G_config.h: New stub headers which issue a deprecation warning and then include <bits/libio.h>, <bits/_G_config.h> respectively. * libio/libio.h: Rename the original version of this file to libio/bits/libio.h. Error out if not included by stdio.h or the stub libio.h. * include/libio.h: Move to include/bits. Forward to libio/bits/libio.h. * sysdeps/generic/_G_config.h: Move to top-level bits/. Error out if not included by bits/libio.h or the stub _G_config.h. * sysdeps/unix/sysv/linux/_G_config.h: Move to sysdeps/unix/sysv/linux/bits. Error out if not included by bits/libio.h or the stub _G_config.h. * libio/stdio.h: Include bits/libio.h, not libio.h. * libio/Makefile: Install bits/libio.h and bits/_G_config.h as well as libio.h and _G_config.h. * csu/init.c, libio/fmemopen.c, libio/iolibio.h, libio/oldfmemopen.c * libio/strfile.h, stdio-common/vfscanf.c * sysdeps/pthread/flockfile.c, sysdeps/pthread/funlockfile.c Include stdio.h, not _G_config.h nor libio.h. * libio/iofgetpos.c: Also rename fgetpos64 out of the way. * libio/iofsetpos.c: Also rename fsetpos64 out of the way. * scripts/check-installed-headers.sh: Skip libio.h and _G_config.h.
2017-12-21Add aarch64 disable-multi-arch variant to build-many-glibcs.pySzabolcs Nagy1-1/+3
aarch64 has several ifuncs now so test it without multiarch support separately. * scripts/build-many-glibcs.py (Context.add_all_configs): Add disable-multi-arch variant to aarch64-linux-gnu.

2017-12-20Remove tilepro-*-linux-gnu supportAdhemerval Zanella1-2/+0
As from previous discussions [1] this patch removes tileprox-*-linux-gnu support from GLIBC.

2017-12-18Add --enable-static-pie variants to x86_64, x32 and i686H.J. Lu1-0/+9
Since the default GCC and binutils versions used by build-many-glibcs.py, which are GCC 7 branch and binutils 2.29 branch, support static PIE on x86_64, x32 and i686, this patch adds --enable-static-pie glibc variants to x86_64, x32 and i686 to get some coverage for static PIE. Tested with build-many-glibcs.py. * scripts/build-many-glibcs.py (Context.add_all_configs): Add --enable-static-pie variants to x86_64, x32 and i686.
2017-12-19Fix build-many-glibcs.py arm-linux-gnueabihf builds with mainline GCC.Joseph Myers1-5/+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.
2017-12-15Correct build-many-glibcs.py arm-linux-gnueabihf configurations.Joseph Myers1-2/+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.
2017-12-12Remove --with-fp / --without-fp.Joseph Myers1-34/+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. Use this variable instead of with_fp. * configure: Regenerated. * config.make.in (with-fp): Use @libc_cv_with_fp@. * manual/install.texi (Configuring and compiling): Remove --without-fp. * INSTALL: Regenerated. * sysdeps/m68k/preconfigure (with_fp_cond): Define for ColdFire. * sysdeps/mips/preconfigure (with_fp_cond): Define. * sysdeps/powerpc/preconfigure (with_fp_cond): Define for 32-bit. * sysdeps/sh/preconfigure (with_fp_cond): Define. * scripts/build-many-glibcs.py (Context.add_all_configs): Do not use --without-fp to configure glibc.
2017-11-30Remove scripts/update-copyrights handling of intl/plural.c.Joseph Myers1-1/+1
Since this file is no longer checked in, update-copyrights no longer needs to avoid changing it. * scripts/update-copyrights: Do not handle intl/plural.c specially.
2017-11-29Add SPARC --disable-multi-arch builds to build-many-glibcs.py.Joseph Myers1-1/+7
While working on SPARC changes to use libm_alias_* I noticed that the non-multi-arch sparc32/sparcv9/fpu/s_fabs.S was missing compat symbol support for fabsl. This clearly shows inadequate test coverage, so this patch adds SPARC --disable-multi-arch builds to build-many-glibcs.py (the 32-bit one fails testing until that bug is fixed, the 64-bit one passes testing). * scripts/build-many-glibcs.py (Context.add_all_configs): Add SPARC --disable-multi-arch glibc variants.
2017-11-15Use Linux 4.14 in build-many-glibcs.py.Joseph Myers1-1/+1
* scripts/build-many-glibcs.py (Context.checkout): Default Linux kernel version to 4.14.
2017-10-17Fix armv7-a compiler option nameAdhemerval Zanella1-2/+2
This patch fixes the wrong -march name option used to define the ARMv7-A glibc variant pushed on commit 3d26560.
2017-10-17Add build-many-glibcs.py arm-linux-gnueabihf-v7{-disable-multiarch}Adhemerval Zanella1-1/+6
This patch adds two extra configuration for arm-linux-gnueabihf to cover for multiarch support: 1. arm-linux-gnueabihf-v7a: enables multiarch support by using -march=armv7a. 2. Same as 1. but with --disable-multiarch. Check with build-many-glibcs.py for both options. * scripts/build-many-glibcs.py (Context.add_all_configs): Add arm-linux-gnueabihf multiarch extra_glibcs.
2017-10-05Remove add-ons mechanism.Joseph Myers3-33/+5
glibc has an add-ons mechanism to allow additional software to be integrated into the glibc build. Such add-ons may be within the glibc source tree, or outside it at a path passed to the --enable-add-ons configure option. localedata and crypt were once add-ons, distributed in separate release tarballs, but long since stopped using that mechanism. Linuxthreads was always an add-on. Ports spent some time as an add-on with separate release tarballs, then was first moved into the glibc source tree, then had its sysdeps files moved into the main sysdeps hierarchy so the add-ons mechanism was no longer used. NPTL spent some time as an add-on in the main glibc tree before stopping using the add-on mechanism. libidn used to have separate release tarballs but no longer does so, but still uses the add-ons mechanism within the glibc source tree. Various other software has supported building with the add-ons mechanism at times in the past, but I don't think any is still widely used. Add-ons involve significant, little-used complexity in the glibc build system, and make it hard to understand what the space of possible glibc configurations is. This patch removes the add-ons mechanism. libidn is now built via the Subdirs mechanism to cause any configuration using sysdeps/unix/inet to build libidn; HAVE_LIBIDN (which effectively means shared libraries are available) is now defined via sysdeps/unix/inet/configure. Various references to add-ons around the source tree are removed (in the case of maint.texi, the example list of sysdeps directories is still very out of date). Externally maintained ports should now put their files in the normal sysdeps directory structure rather than being arranged as add-ons; they probably need to change e.g. elf.h anyway, rather than actually being able to work just as a drop-in subtree. Hurd libpthread should be arranged similarly to NPTL, so some files might go in a hurd-pthreads (or similar) top-level directory in glibc, while sysdeps files should go in the normal sysdeps directory structure (possibly in hurd or hurd-pthreads subdirectories, just as there are nptl subdirectories in the sysdeps tree). Tested for x86_64, and with build-many-glibcs.py. * configure.ac (--enable-add-ons): Remove option. (machine): Do not mention add-ons in comment. (LIBC_PRECONFIGURE): Likewise. (add_ons): Remove variable and sanity checks and logic to locate add-ons. (add_ons_automatic): Remove variable. (configured_add_ons): Likewise. (add_ons_sfx): Likewise. (add_ons_pfx): Likewise.

2017-10-04crypt: Use NSPR header files in addition to NSS header files [BZ #17956]Guido Trentalancia1-1/+1
When configuring and building GNU libc using the Mozilla NSS library for cryptography (--enable-nss-crypt option), also include the NSPR header files along with the Mozilla NSS library header files. Finally, when running the check-local-headers test, ignore the Mozilla NSPR library header files (used by the Mozilla NSS library).
2017-09-27Fix range check in do_tunable_update_valAlexey Makhalov1-2/+10
Current implementation of tunables does not set arena_max and arena_test values. Any value provided by glibc.malloc.arena_max and glibc.malloc.arena_test parameters is ignored. These tunables have minval value set to 1 (see elf/dl-tunables.list file) and undefined maxval value. In that case default value (which is 0. see scripts/gen-tunables.awk) is being used to set maxval. For instance, generated tunable_list[] entry for arena_max is: (gdb) p *cur $1 = {name = 0x7ffff7df6217 "glibc.malloc.arena_max", type = {type_code = TUNABLE_TYPE_SIZE_T, min = 1, max = 0}, val = {numval = 0, strval = 0x0}, initialized = false, security_level = TUNABLE_SECLEVEL_SXID_IGNORE, env_alias = 0x7ffff7df622e "MALLOC_ARENA_MAX"} As a result, any value of glibc.malloc.arena_max is ignored by TUNABLE_SET_VAL_IF_VALID_RANGE macro __type min = (__cur)->type.min; <- initialized to 1 __type max = (__cur)->type.max; <- initialized to 0! if (min == max) <- false { min = __default_min; max = __default_max; } if ((__type) (__val) >= min && (__type) (val) <= max) <- false { (__cur)->val.numval = val; (__cur)->initialized = true; } Assigning correct min/max values at a build time fixes a problem. Plus, a bit of optimization: Setting of default min/max values for the given type at a run time might be eliminated. * elf/dl-tunables.c (do_tunable_update_val): Range checking fix. * scripts/gen-tunables.awk: Set unspecified minval and/or maxval values to correct default value for given type.

2017-06-07tunables: Add LD_HWCAP_MASK to tunablesSiddhesh Poyarekar1-0/+1
Add LD_HWCAP_MASK to tunables in preparation of it being removed from rtld.c. This allows us to read LD_HWCAP_MASK much earlier so that it can influence IFUNC resolution in aarch64. This patch does not actually do anything other than read the LD_HWCAP_MASK variable and add the tunables way to set the LD_HWCAP_MASK, i.e. via the glibc.tune.hwcap_mask tunable. In a follow-up patch, the _dl_hwcap_mask will be replaced with glibc.tune.hwcap_mask to complete the transition. * elf/dl-tunables.list: Add glibc.tune.hwcap_mask. * scripts/gen-tunables.awk: Include dl-procinfo.h. * manual/tunables.texi: Document glibc.tune.hwcap_mask.
2017-05-19Also create and use ldbl-compat-choose.h.Joseph Myers1-0/+19
This patch makes the glibc build generate an additional header ldbl-compat-choose.h that defines LONG_DOUBLE_COMPAT_CHOOSE_* macros for each libc and libm symbol, which select one or the other of their arguments based on whether the symbol was added before a change to long double != double. The effect of this is that it is then possible to define a macro maybe_long_double_symbol that automatically acts as either long_double_symbol or weak_alias depending on when the symbol being defined was added. This can be used when building long double functions from type-generic templates. Thus, with this patch ldbl-opt no longer needs special long double implementations of each new libm function added using such a template, and the existing such implementations are removed. This is a step towards being able more generally to use common macros to create all the aliases needed for a libm function, so reducing the amount of special-case code needed in ldbl-opt and ldbl-64-128, and facilitating subsequently adding *f32 / *f64 / *f128 / *f32x / *f64x aliases to existing functions (where the set of aliases that a function should have may depend on the architecture in various ways). Tested with build-many-glibcs.py. Except for on powerpc64le-linux-gnu, installed stripped shared libraries are unchanged by the patch. powerpc64le-linux-gnu is the unique configuration which used ldbl-opt from the start rather than adding a new long double choice after originally only having had long double = double. The effect of the patch there is that various cases that previously used long_double_symbol unconditionally now use weak_alias instead, so .os files contain e.g. a symbol cabsl instead of cabsl@@GLIBC_2.17. The final dynamic symbols and versions in the resulting shared libraries are unchanged (ABI tests pass), as is the disassembly of the shared libraries, but the differences in the .os files still result in different .gnu_hash contents in libm.so; the differences are of no significance and logically using weak_alias is what's most appropriate in those cases. * scripts/versions.awk: Generate ldbl-compat-choose.h. * sysdeps/ieee754/ldbl-opt/math-type-macros-ldouble.h: Include <ldbl-compat-choose.h>.

2017-05-19Create and use first-versions.h with macros for function symbol versions.Joseph Myers1-0/+17
This patch arranges for the glibc build to generate a header first-versions.h that defines macros for the earliest symbol version in which each public symbol (GLIBC_[0-9]* symbol version, name only uses C identifier characters) is available. This is used in sysdeps/ieee754/ldbl-opt/math-type-macros-double.h to replace the manually defined LDOUBLE_*_libm_version macros for various functions defined using type-generic templates, the purpose of which is to use in LONG_DOUBLE_COMPAT tests "was this function originally added before glibc supported long double != double on this platform?". As discussed in <https://sourceware.org/ml/libc-alpha/2016-12/msg00246.html>, I expect this to be useful more generally in reducing the amount of special-case code needed in ldbl-opt and ldbl-64-128. Tested with build-many-glibcs.py that installed stripped shared libraries are unchanged by this patch. * scripts/versions.awk: Generate first-versions.h. * sysdeps/ieee754/ldbl-opt/math-type-macros-double.h: Include <first-versions.h>.

2017-05-11tunables: Make tunable_list relroSiddhesh Poyarekar1-1/+1
As of now we don't need tunables to be writable after they have been set initially, so there is no point in having them writable. Put tunable_list in .data.rel.ro so that it is set as read-only after relocation. This also allows us to move some of the dl_* variables that are tunables controlled into the tunables infrastructure instead of having two copies. In future if we ever need specific tunables to be writable at runtime, we can split the tunable_list into two. Regression tested on x86_64 to verify that tests continue to pass. * scripts/gen-tunables.awk: Add attribute_relro to tunable_list.

2017-03-16Remove C++ namespace handling from glibc headers.Joseph Myers1-47/+0
glibc headers include some code (not particularly consistent or systematic) to put various declarations in C++ namespaces std and __c99, if _GLIBCPP_USE_NAMESPACES is defined. As noted in <https://gcc.gnu.org/ml/libstdc++/2017-03/msg00025.html>, this macro was removed from libstdc++ in 2000. I don't expect compilation with such old versions of libstdc++ to work with current glibc headers anyway (whereas old *binaries* are expected to stay working with current glibc); this patch (which should be a no-op with any libstdc++ version postdating that removal) removes all this code from the glibc headers. The begin-end-check.pl test, whose comments say it is about checking these namespace macro calls, is also removed. The code in that test would have covered __BEGIN_DECLS / __END_DECLS as well, but if those weren't properly matched it would show up with the check-installed-headers-cxx tests, so I don't think there is an actual use for keeping begin-end-check.pl with the namespace code removed. Tested for x86_64 and x86 (testsuite, and that installed stripped shared libraries are unchanged by the patch). * misc/sys/cdefs.h (__BEGIN_NAMESPACE_STD): Remove macro.
