* Implement STB_GNU_UNIQUE handling.Ulrich Drepper2009-07-091-0/+15
| | | | | | | | | Some symbols have to be identified process-wide by their name. This is particularly important for some C++ features (e.g., class local static data and static variables in inline functions). This cannot completely be implemented with ELF functionality so far. The STB_GNU_UNIQUE binding helps by ensuring the dynamic linker will always use the same definition for all symbols with the same name and this binding.
* Fix wrong PPC_FEATURE_* values.Andreas Schwab2009-07-051-2/+2
| | | | | Nothing uses these wrong values yet, but it fixes a warning due to conflicting definitions in <asm/cputable.h>.
* Minor cleanups in recently added files.Ulrich Drepper2009-07-032-79/+57
|
* Align functions to 16-byte boundary.Ulrich Drepper2009-07-034-0/+4
| | | | | | Some of the new multi-arch string functions for x86-64 were not aligned to 16 byte boundarie,s possibly creating unnecessary cache line misses and delays.
* Add SSE4.2 support for strcspn, strpbrk, and strspn on x86-64.H.J. Lu2009-07-039-7/+851
|
* Fix handling of xmm6 in ld.so audit hooks on x86-64.H.J. Lu2009-07-021-2/+4
|
* Whitespace fixes in last patch.Ulrich Drepper2009-07-021-31/+31
|
* SSSE3 strcpy/stpcpy for x86-64H.J. Lu2009-07-027-1/+1950
| | | | | | This patch adds SSSE3 strcpy/stpcpy. I got up to 4X speed up on Core 2 and Core i7. I disabled it on Atom since SSSE3 version is slower for shorter (<64byte) data.
* Regenerated.Ulrich Drepper2009-06-301-6/+38
|
* Fix little checkin problem in last patch.Ulrich Drepper2009-06-301-2/+2
|

|
* Fix text relocation on ppc32.Andreas Schwab2009-06-251-2/+21
| | | | | The ____longjmp_chk implementation didn't load from memory the right way.
* Fix cfa offset for saved registers in PPC sqrt implementations.Andreas Schwab2009-06-244-8/+8
|
* Clean up whitespaces in last patch.Ulrich Drepper2009-06-221-1/+1

* Add SSE4.2 support for strcmp and strncmp on x86-64.H.J. Lu2009-06-225-0/+1695
|
* Add 802.15.4 definitions to header files.Ulrich Drepper2009-06-183-5/+21
|
* Don't treat bug reporting message as a format string.Andreas Schwab2009-06-161-2/+2
|
* Extend pt_chown to drop privileges.Ulrich Drepper2009-06-162-3/+7
| | | | | | If libcap is available, use it to drop privileges in pt_chown before starting the work to change the permissions and ownership of the slave device.
* Fix x86-64 memchr for large lengths.Jakub Jelinek2009-06-161-3/+3
|
* Fix incorrect use of cmpldi in 32-bit PPC code.Ryan S. Arnold2009-06-162-31/+31
| | | | | The 32-bit PowerPC POWER6 memcpy uses the cmpldi insn when it should use a cmplwi. BZ #10107
* Add missing include.Ulrich Drepper2009-06-161-0/+1
|
* Fold Linux-specific grantpt code into Unix version.Ulrich Drepper2009-06-162-91/+19
|
* Fix permission of slave device on devpts if necessary.Ulrich Drepper2009-06-151-3/+10
| | | | | If devptr is misconfigured the slave device permission after grantpt might not be 0620. BZ #10166
* Preserve message printed before abort.Ulrich Drepper2009-06-152-2/+33
| | | | | | | The terminal output etc is not visible in a core file. The new libc-internal variable __abort_msg will point to a string with the message which has been printed before the abort in case abort is called from inside libc. BZ #10217
* libc part of prelink IFUNC support.Jakub Jelinek2009-06-151-1/+1
| | | | | | The dl-lookup.c changes are needed for prelink (support in prelink checked into SVN, tested for both i?86 and x86-64), dl-irel.h just something I discovered by code inspection.
* Fix warnings when using <sys/select.h>.Ulrich Drepper2009-06-141-30/+6
| | | | | gcc 4.4 is more picky. And the x86-64 version of <bits/select.h> contained a now unnecessary asm optimization. Remove it.
* Add SSE4.2 optimized rawmemchr implementation for x86-64.Ulrich Drepper2009-06-052-4/+96
|
* Forgot some more cleanups for the SSE4.2 strlen on x86-64.Ulrich Drepper2009-06-051-2/+7
|
* Add missing cleanups from SSE4.2 x86-64 strlen.Ulrich Drepper2009-06-051-3/+4
|
* Optimize x86-64 strlen for SSE4.2.Ulrich Drepper2009-06-054-1/+104
| | | | | The SSE4.2 implementation is used in the DSO only. The patch also adds some infrastructure to be used in similar code later one.
* More small optimizations for x86-64 strlen.Ulrich Drepper2009-06-041-9/+7
|
* Tiny strlen for x86-64 optimization.Ulrich Drepper2009-06-041-1/+0
| | | | | I didn't remove an instruction from a previous version in the final version.
* Small optimization of STT_GNU_IFUNC handling.Ulrich Drepper2009-06-012-4/+4
| | | | | | | | The test to call the indirect function now includes a subtest to checked whether the symbol is defined. When coming to that point this is almost always the case. The test for STT_GNU_IFUNC on the other hand rarely is true. Move it to the front means we don't have to perform the second test unless really necessary.
* Better error message for invalid relocatio in static binary.Ulrich Drepper2009-06-012-2/+4
|
* Fix up sched_cpucount in x86-64.Ulrich Drepper2009-05-311-13/+9
| | | | | Now that static executables can handle IFUNC functions don't exclude optimization for sched_cpucount for !SHARED.
* Finish IFUNC support for x86 and x86-64.Ulrich Drepper2009-05-315-0/+147
| | | | Add support for the IRELAIVE relocation and IFUNC in static executables.
* Simplify CPUID value handling.Ulrich Drepper2009-05-314-36/+19
| | | | | | | SO far Intel and AMD use exactly the same bits meaning the same things in CPUID index 1. Simplify the code. Should an architecture come along which doesn't use the same semantics then it must use a different index value than COMMON_CPUID_INDEX_1.
* Add missing file from accept4 commit.Ulrich Drepper2009-05-311-0/+1
| | | | Hidden by previous .gitignore content.
* Fix errno for boundary conditions in 128-bit long double.Ulrich Drepper2009-05-294-4/+32
| | | | | Similar to the changes which went already in for the other formats, follow POSIX rules for errno.
* Implement longjmp checking for s390.Ulrich Drepper2009-05-294-2/+94
|
* Compact cache info data structure for x86/x86-64.Ulrich Drepper2009-05-292-155/+155
| | | | This saves about 1.5kB in the DSO.
* Fix errno for IBM long double.Andreas Schwab2009-05-224-7/+22
| | | | | After the last addition to the math test suite PPC routines haven't been adjusted so far.
* Add ___longjmp_chk support for powerpc{32,64}.Andreas Schwab2009-05-225-5/+107
|
* Implement accept4 for more archs using socketcall.Jakub Jelinek2009-05-224-4/+63
| | | | | So far accept4 was only supported on archs using socketcall for x86. This patch adds support for the remaining archs.
* Add missing file from previous IA-64 longjmp commit.Ulrich Drepper2009-05-211-0/+48
|
* Handle -g option for IA-64 assembler.Ulrich Drepper2009-05-212-0/+89
|
* Fix IA-64 memchr read-ahead.Ulrich Drepper2009-05-211-1/+16
| | | | | | The latest stratcliff extension exposed a bug in the IA-64 memchr which uses non-speculative loads to prefetch data. Change the code to use speculative loads with appropriate fixup. Fixes BZ 10162.
* Add ____longjmp_chk support for IA-64.H.J. Lu2009-05-211-1/+9
|
* Add missing .text directives.H.J. Lu2009-05-212-1/+3
| | | | The ____longjmp_chk functions on x86 and x86-64 were placed in .rodata.str1.1.
* Don't define __ASSUME_ACCEPT4 for IA-64.Ulrich Drepper2009-05-211-1/+1
