* Fix typo in macro names in sysconf.cSiddhesh Poyarekar2014-09-122-2/+7
| | | | | | | | | Spell _POSIX_DEVICE_SPECIFIC and _POSIX_DEVICE_SPECIFIC_R correctly. Found when trying to make the getconf environment variables typo-proof. * sysdeps/posix/sysconf.c (__sysconf): Spell _POSIX_DEVICE_SPECIFIC and _POSIX_DEVICE_SPECIFIC_R correctly.
* Complete the removal of __gconv_translit_findFlorian Weimer2014-09-1220-287/+75
| | | | | | | | | Prior to the 2.20 release, the function was just changed to fail unconditionally, in commit a1a6a401ab0a3c9f15fb7eaebbdcee24192254e8. This commit removes the function completely, including gconv bits which depend on it. This changes the gconv ABI, which is not a public interface.
* Enhance tst-xmmymm.sh to detect zmm register usage in ld.so (BZ #16194)Siddhesh Poyarekar2014-09-123-6/+14
| | | | | | | | | | | | | | | | 2d63a517e4084ec80403cd9f278690fa8b676cc4 added support to save and restore zmm register in the dynamic linker, but did not enhance test-xmmymm.sh to detect accidental usage of these registers. The patch below adds that check. The script has also been renamed to tst-ld-sse-use.sh. To see the minimal changes, run `git show -M`. [BZ #16194] * sysdeps/x86/tst-xmmymm.sh: Rename file to... * sysdeps/x86/tst-ld-sse-use.sh: ... this. Check for zmm register usage. * sysdeps/x86/Makefile: Adjust.

* malloc: additional unlink hardening for non-small bins [BZ #17344]Florian Weimer2014-09-113-3/+11
| | | | | | Turn two asserts into a conditional call to malloc_printerr. The memory locations are accessed later anyway, so the performance impact is minor.

* Return failure in getnetgrent only when all netgroups have been searched ↵Siddhesh Poyarekar2014-09-103-1/+16
| | | | | | | | | | | | | | | | (#17363) The netgroups lookup code fails when one of the groups in the search tree is empty. In such a case it only returns the leaves of the tree after the blank netgroup. This is because the line parser returns a NOTFOUND status when the netgroup exists but is empty. The __getnetgrent_internal implementation needs to be fixed to try remaining groups if the current group is entry. This patch implements this fix. Tested on x86_64. [BZ #17363] * inet/getnetgrent_r.c (__internal_getnetgrent_r): Try next group if the current group is empty.
* PowerPC: memset optimization for POWER8/PPC64Adhemerval Zanella2014-09-108-9/+533
| | | | | | | | | | | | | | | | | | | This patch adds an optimized memset implementation for POWER8. For sizes from 0 to 255 bytes, a word/doubleword algorithm similar to POWER7 optimized one is used. For size higher than 255 two strategies are used: 1. If the constant is different than 0, the memory is written with altivec vector instruction; 2. If constant is 0, dbcz instructions are used. The loop is unrolled to clear 512 byte at time. Using vector instructions increases throughput considerable, with a double performance for sizes larger than 1024. The dcbz loops unrolls also shows performance improvement, by doubling throughput for sizes larger than 8192 bytes.
* PowerPC: multiarch bzero cleanup for PPC64Adhemerval Zanella2014-09-1011-91/+32
| | | | | | | | This patch cleanups the multiarch bzero for powerpc64 by remove the multiarch objects and use instead the the memset embedded implementation presented in each multiarch optimization. The code generate is essentially the same, but the TB_TOCLESS (which is not essential).
* Turn on -Werror=implicit-function-declarationFlorian Weimer2014-09-103-1/+11
| | | | | | | GCC 4.4, the minimum compiler version, supports this option. Unlike other warnings, -Wimplicit-function-declaration warnings should be independent of compiler versions, so this change should not cause compiler-specific build failures.

* HPPA: Add c++-types.data.Carlos O'Donell2014-09-072-0/+71
| | | | | Added c++-types.data to baseline for HPPA. At this point `make check` completes without error, and the full testing results are summarized.
* HPPA: Transition to new non-addon NPTL.Carlos O'Donell2014-09-0719-29/+42
| | | | | | | | | Merge roland/nptl-hppa to master, update and test for hppa-linux-gnu. This commit squashes and commits the work done by Roland McGrath on roland/nptl-hppa to migrate hppa to the new non-addon NPTL. Some additional tweaks were required for tcb-offsets.sym to work correctly along with clone.S (unique to hppa).

* [BZ #17354] tile: Fix up corner cases with signed relocationsChris Metcalf2014-09-063-19/+30
| | | | | | | | | | | | | | | | | | Some types of relocations technically need to be signed rather than unsigned: in particular ones that are used with moveli or movei, or for jump and branch. This is almost never a problem. Jump and branch opcodes are pretty much uniformly resolved by the static linker (unless you omit -fpic for a shared library, which is not recommended). The moveli and movei opcodes that need to be sign-extended generally are for positive displacements, like the construction of the address of main() from _start(). However, tst-pie1 ends up with main below _start (in a different module) and the test failed due to signedness issues in relocation handling. This commit treats the value as signed when shifting (to preserve the high bit) and also sign-extends the value generated from the updated bundle when comparing with the desired bundle, which we do to make sure no overflow occurred. As a result, the tst-pie1 test now passes.

* i386 TLS_INIT_TP might produce bogus asm changing stack pointer [BZ #17319]Mark Wielaard2014-08-283-30/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | TLS_INIT_TP in sysdeps/i386/nptl/tls.h uses some hand written asm to generate a set_thread_area that might result in exchanging ebx and esp around the syscall causing introspection tools like valgrind to loose track of the user stack. Just use INTERNAL_SYSCALL which makes sure esp isn't changed arbitrarily. Before the patch the code would generate: mov $0xf3,%eax movl $0xfffff,0x8(%esp) movl $0x51,0xc(%esp) xchg %esp,%ebx int $0x80 xchg %esp,%ebx Using INTERNAL_SYSCALL instead will generate: movl $0xfffff,0x8(%esp) movl $0x51,0xc(%esp) xchg %ecx,%ebx mov $0xf3,%eax int $0x80 xchg %ecx,%ebx Thanks to Florian Weimer for analysing why the original code generated the bogus esp usage: _segdescr.desc happens to be at the top of the stack, so its address is in %esp. The asm statement says that %3 is an input, so its value will not change, and GCC can use %esp as the input register for the expression &_segdescr.desc. But the constraints do not fully describe the asm statement because the %3 register is actually modified, albeit only temporarily. [BZ #17319] * sysdeps/i386/nptl/tls.h (TLS_INIT_TP): Use INTERNAL_SYSCALL to call set_thread_area instead of hand written asm. (__NR_set_thread_area): Removed define. (TLS_FLAG_WRITABLE): Likewise.

* Remove NOT_IN_libc definition for pthread_atforkSiddhesh Poyarekar2014-08-212-2/+2
| | | | | | | | pthread_atfork is already built in an extra-libs context, which gives it NOT_IN_libc in its CPPFLAGS. Adding the same definition to CFLAGS is pointless. Verified that the code is unchanged on x86_64.

* Fix powerpc32 __get_clockfreq for non-power4 (bug 17263).Joseph Myers2014-08-133-2/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In my powerpc32 testing I've observed misc/test-gettimebasefreq failing. This is a glibc build (soft-float, though that's not relevant here) without any --with-cpu and without any special configuration of the default CPU for GCC either. In particular, it's one not using sysdeps/powerpc/powerpc32/power4/hp-timing.h (although in fact the processor I'm using for testing is POWER4-based), so hp_timing_t is 32-bit not 64-bit. But the VDSO call being used by INTERNAL_VSYSCALL_NO_SYSCALL_FALLBACK is generating a 64-bit result (high part in r3, low part in r4). The code extracting that result, however, expects a result of the type hp_timing_t as passed to INTERNAL_VSYSCALL_NO_SYSCALL_FALLBACK, meaning that only r3 (= 0) is used and the value in r4 is ignored. This patch fixes this by always using uint64_t as the type in INTERNAL_VSYSCALL_NO_SYSCALL_FALLBACK - reflecting the actual ABI (unconditional in the kernel) of that VDSO call. This is the minimal change for this issue - no check for overflow, no change of the type of the timebase_freq variable or the return type of __get_clockfreq to something other than hp_timing_t (such a change would simply move the implicit conversions to the over callers of that function), no change to hp_timing_t itself. Tested for powerpc32 soft float. [BZ #17263] * sysdeps/unix/sysv/linux/powerpc/get_clockfreq.c: Include <stdint.h>. (__get_clockfreq): Use uint64_t instead of hp_timing_t in INTERNAL_VSYSCALL_NO_SYSCALL_FALLBACK call.

* Disable x87 inline functions for x86_64 and SSE [BZ #17262]Siddhesh Poyarekar2014-08-133-3/+12
| | | | | | | | | | | | | | | | | | | | | | | | | Since: commit 409e00bd69b8d8dd74d7327085351d26769ea6fc Author: H.J. Lu <hjl.tools@gmail.com> Date: Wed Jan 29 07:51:41 2014 -0800 Disable x87 inline functions for SSE2 math When i386 and x86-64 mathinline.h was merged into a single mathinline.h, "gcc -m32" enables x87 inline functions on x86-64 even when -mfpmath=sse and SSE2 is enabled. It is a regression on x86-64. We should check __SSE2_MATH__ instead of __x86_64__ when disabling x87 inline functions. gcc-3.2 is unable to correctly compile x86_64 routines for llrint since it gets redefined. This is because gcc 3.2 does not set __SSE2_MATH__ for x86_64, thus exposing the duplicate definition. The correct fix ought to be to check for both __SSE2_MATH__ and __x86_64__ and enable those bits only when neither are defined. Tested fix with the reproducer for 409e00bd69b8d8dd74d7327085351d26769ea6fc as well as with gcc-3.2.
* Replace cpuid asm statement with __cpuid_countH.J. Lu2014-08-123-4/+9
| | | | | | | | | | | The compiler doesn't know that the cpuid asm statement in intel_check_word will trash RBX. We are lucky that it doesn't cause any problems since RBX is also used by compiler for other purposes so that RBX is saved and restored. This patch replaces it with __cpuid_count. [BZ #17259] * sysdeps/x86_64/cacheinfo.c (intel_check_word): Replace cpuid asm statement with __cpuid_count.
