2009-10-19Correct errno handling in expm1.Andreas Schwab
2009-09-15configure tweaks, support $libc_add_on_config_subdirsRoland McGrath
2009-09-03Fix IA-32 strstr in multiarch configuration as well.Ulrich Drepper
2009-08-28Remove ENABLE_SSSE3_ON_ATOM.H.J. Lu
It turns that SSSE3 isn't slow on Atom. The problem is bsf. This patch removes ENABLE_SSSE3_ON_ATOM.
2009-08-24Define math_errhandling is possible.Ulrich Drepper
2009-08-08Use PIC only if SHARED is defined.H.J. Lu
For ia32, we can avoid PIC in IFUNC functions in static library.
2009-08-08Simplify cpuid.h configure test.Jim Meyering
2009-08-07Fix whitespace in last patch.Ulrich Drepper
2009-08-07Add the missing "; \".H.J. Lu
2009-08-04Add x86 SSE strlen.Ulrich Drepper
2009-08-04Add x86 32-bit SSE4.2 string functions.H.J. Lu
This patch adds 32bit SSE4.2 string functions. It uses -16L instead of 0xfffffffffffffff0L, which works for both 32bit and 64bit long. Tested on 32bit Core i7 and Core 2.
2009-08-02x86/x86-64 now needs <cpuid.h> from gcc.Ulrich Drepper
2009-07-31Support multiarch for i686.H.J. Lu
This patch adds multiarch support when configured for i686. I modified some x86-64 functions to support 32bit. I will contribute 32bit SSE string and memory functions later.
2009-07-31Remove CHEC_ESP handling from i386 __longjmp.Ulrich Drepper
2009-07-30Add sigstack handling to Linux ____longjmp_chk on i386.Ulrich Drepper
All other i386 ports need to provide their own versions.
2009-07-03Add SSE4.2 support for strcspn, strpbrk, and strspn on x86-64.H.J. Lu
2009-06-15libc part of prelink IFUNC support.Jakub Jelinek
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.
2009-06-01Small optimization of STT_GNU_IFUNC handling.Ulrich Drepper
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.
2009-06-01Better error message for invalid relocatio in static binary.Ulrich Drepper
2009-05-31Finish IFUNC support for x86 and x86-64.Ulrich Drepper
Add support for the IRELAIVE relocation and IFUNC in static executables.
2009-05-21Add missing .text directives.H.J. Lu
The ____longjmp_chk functions on x86 and x86-64 were placed in .rodata.str1.1.
2009-05-15Check for valid stack frame in longjmp.Ulrich Drepper
If longjmp restores the stack frame to an address which is beyond the stack frame at the time of the longjmp call it would install an uninitialized stack frame. If compiled with _FORTIFY_SOURCE defined, longjmp will now bail out in this situation.
