* S390: Add arch13 strstr ifunc variant.Stefan Liebler2019-03-227-6/+232
| | | | | | | | | | | | | | | | | | | | This patch introduces the new arch13 ifunc variant for strstr. For needles longer than 9 charachters it is relying on the common-code implementation. For shorter needles it is using the new vstrs instruction which is able to search a substring within a vector register. ChangeLog: * sysdeps/s390/Makefile (sysdep_routines): Add strstr-arch13. * sysdeps/s390/ifunc-strstr.h (HAVE_STRSTR_ARCH13, STRSTR_ARCH13, STRSTR_Z13_ONLY_USED_AS_FALLBACK, HAVE_STRSTR_IFUNC_AND_ARCH13_SUPPORT): New defines. * sysdeps/s390/multiarch/ifunc-impl-list.c (__libc_ifunc_impl_list): Add ifunc variant for arch13 strstr. * sysdeps/s390/strstr-arch13.S: New file. * sysdeps/s390/strstr-vx.c: Omit GI symbol for z13 strstr ifunc variant if it is only used as fallback. * sysdeps/s390/strstr.c (strstr): Add arch13 variant in ifunc selector.
* S390: Add arch13 memmove ifunc variant.Stefan Liebler2019-03-226-5/+111
| | | | | | | | | | | | | | | | | | | | | This patch introduces the new arch13 ifunc variant for memmove. For the forward or non-overlapping case it is just using memcpy. For the backward case it relies on the new instruction mvcrl. The instruction copies up to 256 bytes at once. In case of an overlap, it copies the bytes like copying them one by one starting from right to left. ChangeLog: * sysdeps/s390/ifunc-memcpy.h (HAVE_MEMMOVE_ARCH13, MEMMOVE_ARCH13 HAVE_MEMMOVE_IFUNC_AND_ARCH13_SUPPORT): New defines. * sysdeps/s390/memcpy-z900.S: Add arch13 memmove implementation. * sysdeps/s390/memmove.c (memmove): Add arch13 variant in ifunc selector. * sysdeps/s390/multiarch/ifunc-impl-list.c (__libc_ifunc_impl_list): Add ifunc variant for arch13 memmove. * sysdeps/s390/multiarch/ifunc-resolve.h (S390_STFLE_BITS_ARCH13_MIE3, S390_IS_ARCH13_MIE3): New defines.
* S390: Add configure check to detect support for arch13.Stefan Liebler2019-03-224-0/+133
| | | | | | | | | | | | | Add two configure checks which detect if arch13 is supported by the assembler at all - by explicitely setting the machine - and if it is supported with default settings. ChangeLog: * config.h.in (HAVE_S390_MIN_ARCH13_ZARCH_ASM_SUPPORT, HAVE_S390_ARCH13_ASM_SUPPORT): New undefine. * sysdeps/s390/configure.ac: Add checks for arch13 support. * sysdeps/s390/configure: Regenerated.
* S390: Add new hwcap values for new cpu architecture arch13.Stefan Liebler2019-03-224-4/+25

ChangeLog: * sysdeps/s390/dl-procinfo.c (_dl_s390_cap_flags): Add vxe2, vxp, dflt, sort flags. * sysdeps/s390/dl-procinfo.h: Add HWCAP_S390_VXRS_EXT2, HWCAP_S390_VXRS_PDE, HWCAP_S390_SORT, HWCAP_S390_DFLT capabilities.

| | | | | | | | | | | | | Two cases of "int * 1.4" may result in imprecise results, which in at least one case resulted in i686 and x86-64 producing different locale files. This replaced that floating point multiply with integer operations.

| | | | | | | | | | | | | | | | This patch updates sysdeps/unix/sysv/linux/syscall-names.list for Linux 5.0. Based on testing with build-many-glibcs.py, the only new entry needed is for old_getpagesize (a newly added __NR_* name for an old syscall on ia64). (Because 5.0 changes how syscall tables are handled in the kernel, checking diffs wasn't a useful way of looking for new syscalls in 5.0 as most of the syscall tables were moved to the new representation without actually adding any syscalls to them.) Tested with build-many-glibcs.py. * sysdeps/unix/sysv/linux/syscall-names.list: Update kernel version to 5.0. (old_getpagesize): New syscall.

* Remove obsolete, never-implemented XSI STREAMS declarationsFlorian Weimer2019-03-1437-952/+166
| | | | | | | | | | | | | | | | | | | The stub implementations are turned into compat symbols. Linux actually has two reserved system call numbers (for getpmsg and putpmsg), but these system calls have never been implemented, and there are no plans to implement them, so this patch replaces the wrappers with the generic stubs. According to <https://bugzilla.redhat.com/show_bug.cgi?id=436349>, the presence of the XSI STREAMS declarations is a minor portability hazard because they are not actually implemented. This commit does not change the TIRPC support code in sunrpc/rpc_svcout.c. It uses additional XTI functionality and therefore never worked with glibc. Reviewed-by: Carlos O'Donell <carlos@redhat.com>

* Use Linux 5.0 in build-many-glibcs.py.Joseph Myers2019-03-132-3/+11
| | | | | | | | | | | | | | | | | 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.

* Use a proper C tokenizer to implement the obsolete typedefs test.Zack Weinberg2019-03-136-63/+516
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Fix output of LD_SHOW_AUXV=1.Stefan Liebler2019-03-137-16/+25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Starting with commit 1616d034b61622836d3a36af53dcfca7624c844e the output was corrupted on some platforms as _dl_procinfo was called for every auxv entry and on some architectures like s390 all entries were represented as "AT_HWCAP". This patch is removing the condition and let _dl_procinfo decide if an entry is printed in a platform specific or generic way. This patch also adjusts all _dl_procinfo implementations which assumed that they are only called for AT_HWCAP or AT_HWCAP2. They are now just returning a non-zero-value for entries which are not handled platform specifc.

| | | | | | | | | | | | | | | | | | | | | | | | Since the commit commit 81a14439417552324ec6ca71f65ddf8e7cdd51c7 Author: Adhemerval Zanella <adhemerval.zanella@linaro.org> Date: Tue Feb 5 17:35:12 2019 -0200 wcsmbs: optimize wcscat powerpc64 and powerpc64le builds fail when configured with --disable-multi-arch and --with-cpu=power6 (or newer), due to an undefined reference to __GI___wcscpy. This patch fixes this on sysdeps/powerpc/powerpc64/power6/wcscpy.c, which is only used when multi-arch is disabled. This patch does nothing for the failures on 32-bits powerpc builds, because the file is under the powerpc64 subdirectory, however, powerpc builds were already failing with --disable-multi-arch, with multiple error messages, even before the aforementioned commit. Tested for powerpc, powerpc64, and powerpc64le with multi-arch enabled (all pass) and disabled (powerpc still fails as explained above).

* ldbl-opt: Reuse test cases from misc/ that check long doubleGabriel F. T. Gomes2019-03-014-18/+59
| | | | | | | | | This patch adds test cases for the compatibility versions of the functions: err, errx, verr, verrx, warn, warnx, vwarn, vwarnx (from err.h), error, and error_at_line (from error.h), when long double has the same format as double (-mlong-double-64). Tested for powerpc, powerpc64 and powerpc64le.
* ldbl-opt: Add error and error_at_line (bug 23984)Gabriel F. T. Gomes2019-03-0117-4/+120
| | | | | | | | | | On platforms where long double may have the same format as double (-mlong-double-64), error and error_at_line do not take that into account and might produce wrong output if a long double conversion is requested by the format string ('%Lf'). This patch adds compatibility functions for this situation and redirects calls via header magic. Tested for powerpc, powerpc64 and powerpc64le.
* ldbl-opt: Add err, errx, verr, verrx, warn, warnx, vwarn, and vwarnx (bug 23984)Gabriel F. T. Gomes2019-03-0117-1/+215
| | | | | | | | | | | | | | | When support for long double format with 128-bits (-mlong-double-128) was added for platforms where long double had the same format as double, such as powerpc, compatibility versions for the functions listed in the commit title were missed. Since the older format of long double can still be used (with -mlong-double-64), using these functions with a format string that requests the printing of long double variables will produce wrong outputs. This patch adds the missing compatibility functions and header magic to redirect calls to them when -mlong-double-64 is in use. Tested for powerpc, powerpc64 and powerpc64le.
* ldbl-opt: Reuse argp tests that print long doubleGabriel F. T. Gomes2019-03-012-0/+17
| | | | | | | | | The test case tst-ldbl-argp checks that the conversion specifier '%Lf' correctly prints long double values with the default long double format for a platform. This patch reuses the test case for long double with the same format as double (-mlong-double-64). Tested for powerpc, powerpc64 and powerpc64le.
* ldbl-opt: Add argp_error and argp_failure (bug 23983)Gabriel F. T. Gomes2019-03-0117-1/+112
| | | | | | | | | | The functions argp_error and argp_failure are missing support for printing long double values when long double has the same format as double. This patch adds the new functions __nldbl_argp_error and __nldbl_argp_failure, as well as header magic to redirect calls to them when -mlong-double-64 is in use. Tested for powerpc, powerpc64 and powerpc64le.
* elf/tst-big-note: Improve accuracy of test [BZ #20419]Florian Weimer2019-03-013-4/+23
| | | | | | | | | | | | | | | | It is possible that the link editor injects an allocated ABI tag note before the artificial, allocated large note in the test. Note parsing in open_verify stops when the first ABI tag note is encountered, so if the ABI tag note comes first, the problematic code is not actually exercised. Also tweak the artificial note so that it is a syntactically valid 4-byte aligned note, in case the link editor tries to parse notes and process them. Improves the testing part of commit 0065aaaaae51cd60210ec3a7e13. Reviewed-by: Carlos O'Donell <carlos@redhat.com>
* S390: Fix introduction of __wcscpy and weak wcscpy symbols.Stefan Liebler2019-03-012-1/+10
| | | | | | | | | | | | The recent commit 81a14439417552324ec6ca71f65ddf8e7cdd51c7 has introduced __wcscpy, __GI___wcscpy and the weak alias wcscpy. This patch also introduces those symbols if glibc is build with CFLAGS="-march=z13" where the ifunc is omitted. ChangeLog: * sysdeps/s390/wcscpy-vx.S: Add strong aliases to __wcscpy, __GI___wcscpy and weak alias to wcscpy.

* elf: Add tests with a local IFUNC resolver [BZ #23937]Florian Weimer2019-02-287-3/+139
| | | | | | | | | | | | The existing tests all use global symbols (but with different visibility). Local symbols could be treated differently by the compiler and linker (as was the case on POWER ELFv2, causing bug 23937), and we did not have test coverage for this. Tested on x86-64 and POWER ELFv2 little-endian, with and without --disable-multi-arch. On POWER, the test cases elf/ifuncmain9, elf/ifuncmain9pic, elf/ifuncmain9pie reproduce bug 23937 with older binutils.
