* Support mixed SSE/AVX audit and check AVX only once.H.J. Lu2009-08-0811-239/+1062
| | | | | | | | | | This patch fixes mixed SSE/AVX audit and checks AVX only once in _dl_runtime_profile. When an AVX or SSE register value in pltenter is modified, we have to make sure that the SSE part value is the same in both lr_xmm and lr_vector fields so that pltexit will get the correct value from either lr_xmm or lr_vector fields. AVX-enabled pltenter should update both lr_xmm and lr_vector fields to support stacked AVX/SSE pltenter functions.
* Use PIC only if SHARED is defined.H.J. Lu2009-08-083-0/+36
| | | | For ia32, we can avoid PIC in IFUNC functions in static library.

* Properly count number of logical processors on Intel CPUs.H.J. Lu2009-08-072-4/+43
| | | | | | | | | | | | | | | | | | | | The meaning of the 25-14 bits in EAX returned from cpuid with EAX = 4 has been changed from "the maximum number of threads sharing the cache" to "the maximum number of addressable IDs for logical processors sharing the cache" if cpuid takes EAX = 11. We need to use results from both EAX = 4 and EAX = 11 to get the number of threads sharing the cache. The 25-14 bits in EAX on Core i7 is 15 although the number of logical processors is 8. Here is a white paper on this: http://software.intel.com/en-us/articles/intel-64-architecture-processor-topology-enumeration/ This patch correctly counts number of logical processors on Intel CPUs with EAX = 11 support on cpuid. Tested on Dinnington, Core i7 and Nehalem EX/EP. It also fixed Pentium Ds workaround since EBX may not have the right value returned from cpuid with EAX = 1.
* Fix sed expression in TAGS command.Andreas Schwab2009-08-072-2/+7
| | | | | The backslash-newline pair is interpreted as the beginning of an address regex.

* Add x86 SSE strlen.Ulrich Drepper2009-08-044-6/+166
|
* Add x86 32-bit SSE4.2 string functions.H.J. Lu2009-08-0414-4/+243
| | | | | | 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.
* Optimize x86-64 syscall cancellation handling.Ulrich Drepper2009-08-046-44/+191
| | | | | | | The syscall wrappers had to save and restore the syscall parameter values and return value when calling the functions to enable/disable cancellation were called. Not anymore. The called functions are special and don't modify any unexpected registers.

* Support multiarch for i686.H.J. Lu2009-07-3113-49/+125
| | | | | | 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.
* Fix obstack* on i?86Jakub Jelinek2009-07-312-0/+5
| | | | | | obstack calls several callbacks, so on i?86 it'd better be compiled without -mpreferred-stack-boundary=2, otherwise the callbacks are called with misaligned stack.

* Add sigstack handling to Linux ____longjmp_chk on i386.Ulrich Drepper2009-07-304-61/+156
| | | | All other i386 ports need to provide their own versions.
* ____longjmp_chk is now OS-specific.Ulrich Drepper2009-07-303-145/+151
| | | | | | | We use sigaltstack internally which on some systems is a syscall and should be used as such. Move the x86-64 version to the Linux specific directory and create in its place a file which always causes compile errors.
* Change code a bit to correct CFI.Ulrich Drepper2009-07-301-1/+3

|
* Fix x86-64 ____longjmp_chk to handle signal stacks.Ulrich Drepper2009-07-303-7/+111
| | | | | | The simple test previously used might trigger if the longjmp jumps from the signal stack to the normal stack. We now explicitly test for this case.
* Stop backtrace when we make no more progress.Ulrich Drepper2009-07-302-2/+13

* Add support for x86-64 fma instruction.Ulrich Drepper2009-07-296-2/+110
