* iconv: Revert steps array reference counting changesFlorian Weimer2019-07-318-132/+31
| | | | | | | | | | | | | | | The changes introduce a memory leak for gconv steps arrays whose first element is an internal conversion, which has a fixed reference count which is not decremented. As a result, after the change in commit 50ce3eae5ba304650459d4441d7d246a7cefc26f, the steps array is never freed, resulting in an unbounded memory leak. This reverts commit 50ce3eae5ba304650459d4441d7d246a7cefc26f ("gconv: Check reference count in __gconv_release_cache [BZ #24677]") and commit 7e740ab2e7be7d83b75513aa406e0b10875f7f9c ("libio: Fix gconv-related memory leak [BZ #24583]"). It reintroduces bug 24583. (Bug 24677 was just a regression caused by the second commit.)
* Restore r31 setting in powerpc32 swapcontext.Joseph Myers2019-07-302-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | Commit ffe8a9a8318e1db225b22da8bc067408494bac5c, "powerpc: Remove rt_sigreturn usage on context function", removed from powerpc32 swapcontext a setting of r31 that is relied upon in subsequent code. I'm not sure why this didn't produce test failures in Adhemerval's 32-bit testing; in my (soft-float) testing in preparation for 2.30 release, I see several context-related failures FAIL: stdlib/tst-makecontext2 FAIL: stdlib/tst-makecontext3 FAIL: stdlib/tst-setcontext FAIL: stdlib/tst-setcontext2 FAIL: stdlib/tst-setcontext4 FAIL: stdlib/tst-setcontext7 FAIL: stdlib/tst-setcontext9 FAIL: stdlib/tst-swapcontext1 that did not appear in 2.29 testing. This patch restores the removed register setting in question, and thus fixes those failures. Tested for powerpc (soft-float). * sysdeps/unix/sysv/linux/powerpc/powerpc32/swapcontext-common.S (__CONTEXT_FUNC_NAME): Restore setting of r31.

* x86-64: Compile branred.c with -mprefer-vector-width=128 [BZ #24603]H.J. Lu2019-07-244-0/+52
| | | | | | | | | | | | | | | | | | | | | When compiled with -O3 and AVX, GCC 8 and 9 optimize some loops in sysdeps/ieee754/dbl-64/branred.c with 256-bit vector instructions, which leads to store forward stall: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=90579 There is no easy fix in compiler. This patch limits vector width to 128 bits to work around this issue. It improves performance of sin and cos by more than 40% on Skylake compiled with -O3 -march=skylake. Tested with GCC 7/8/9 on x86-64. [BZ #24603] * sysdeps/x86_64/configure.ac: Check if -mprefer-vector-width=128 works. * sysdeps/x86_64/configure: Regenerated. * sysdeps/x86_64/fpu/Makefile (CFLAGS-branred.c): New.

* Linux: Use in-tree copy of SO_ constants for !__USE_MISC [BZ #24532]Florian Weimer2019-07-2410-94/+333
| | | | | | | | | | | | | | | | | | | | The kernel changes for a 64-bit time_t on 32-bit architectures resulted in <asm/socket.h> indirectly including <linux/posix_types.h>. The latter is not namespace-clean for the POSIX version of <sys/socket.h>. This issue has persisted across several Linux releases, so this commit creates our own copy of the SO_* definitions for !__USE_MISC mode. The new test socket/tst-socket-consts ensures that the copy is consistent with the kernel definitions (which vary across architectures). The test is tricky to get right because CPPFLAGS includes include/libc-symbols.h, which in turn defines _GNU_SOURCE unconditionally. Tested with build-many-glibcs.py. I verified that a discrepancy in the definitions actually results in a failure of the socket/tst-socket-consts test.
* test-container: Install with $(all-subdirs) [BZ #24794]Tulio Magno Quites Machado Filho2019-07-232-1/+6
| | | | | | | | | | | | | Whenever a sub-make is created, it inherits the variable subdirs from its parent. This is also true when make check is called with a restricted list of subdirs. In this scenario, make install is executed "partially" and testroot.pristine ends up with an incomplete installation. [BZ #24794] * Makefile (testroot.pristine/install.stamp): Pass subdirs='$(all-subdirs)' to make install. Reviewed-by: DJ Delorie <dj@redhat.com>
* test-container: Avoid copying unintended system librariesTulio Magno Quites Machado Filho2019-07-232-2/+7
| | | | | | | | | | | | | | Some DSOs are distributed in hardware capability directories, e.g. /usr/lib64/power7/libc.so.6 Whenever the processor is able to use one of these hardware-enabled DSOs, testroot.pristine ends up with copies of glibc-provided libraries from the system because it can't overwrite or remove them. This patch avoids the unintended copies by executing ld.so with the same arguments passed to each glibc test. * Makefile (testroot.pristine/install.stamp): Execute ld.so with the same arguments used in all tests.

* Afar locales: Months and days updated from CLDR (bug 21897).Rafal Luzynski2019-07-175-12/+30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit updates month and weekday names (full and abbreviated) from CLDR 35.1 with the following exceptions. It was not clear why the full name of February in aa_DJ and aa_ER was "Kudo" while the abbreviated version is "Nah" but some additional sources [1] [2] as well as the content of aa_ER and aa_ER@saaho suggest it should be "Naharsi Kudo". This commit consequently sets the translation of February to "Naharsi Kudo" in aa_DJ and aa_ET. aa_ER@saaho is not supported by CLDR but since the month names were identical to aa_ER before this commit, the same values have been copied from aa_ER.
