2009-08-10Fix check for PI mutex in x86-64 pthread_cond_signalAndreas Schwab

2009-08-08Yet more news items.Ulrich Drepper
2009-08-08Support mixed SSE/AVX audit and check AVX only once.H.J. Lu
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.
2009-08-08Use PIC only if SHARED is defined.H.J. Lu
For ia32, we can avoid PIC in IFUNC functions in static library.

2009-08-08Add some news items.Ulrich Drepper
2009-08-07Add SSSE3-optimized implementation of str{,n}cmp for x86-64.Ulrich Drepper
2009-08-07Small optimizations to cancellable x86-64 code.Ulrich Drepper
2009-08-07Avoid warning through fake initialization.Ulrich Drepper
2009-08-07Fix whitespace in last patch.Ulrich Drepper
2009-08-07Add the missing "; \".H.J. Lu
2009-08-07Fix expanding STB_GNU_UNIQUE hash table.Andreas Schwab
An invalid symbol name pointer was entered into the hash table while enlarging it.
2009-08-07Fix whitespaces in last checkin.Ulrich Drepper
2009-08-07Properly count number of logical processors on Intel CPUs.H.J. Lu
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.
2009-08-07Fix sed expression in TAGS command.Andreas Schwab
The backslash-newline pair is interpreted as the beginning of an address regex.
2009-08-06Ignore TAGS.Andreas Schwab
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.
2009-08-04Optimize x86-64 syscall cancellation handling.Ulrich Drepper
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.
2009-08-02Remove leftover code from Linux/x86 ____longjmp_chk.Ulrich Drepper
2009-08-02x86/x86-64 now needs <cpuid.h> from gcc.Ulrich Drepper
2009-08-01Remove last trace of bounded pointer handling from ____longjmp_chk on x86-64.Ulrich Drepper
2009-07-31Macro cleanup.Ulrich Drepper
Better definition of the *_NITSET macros.

2009-07-31Regenerated.Ulrich Drepper
2009-07-31Optimize x86 and x86-64 ____longjmp_chk for Linux.Ulrich Drepper
2009-07-31Fix ____longjmp_chk on x86-64.Ulrich Drepper
After a recent change to fix CFI in ____longjmp_chk the test of the ss_flags used the wrong memory location.
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.
2009-07-31Fix obstack* on i?86Jakub Jelinek
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.
2009-07-31Remove CHEC_ESP handling from i386 __longjmp.Ulrich Drepper
2009-07-30Whitespace cleanup.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.
2009-07-30____longjmp_chk is now OS-specific.Ulrich Drepper
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.
2009-07-30Change code a bit to correct CFI.Ulrich Drepper
2009-07-30Optimize ____longjmp_chk for x86-64 a bit.Ulrich Drepper
2009-07-30Add CFLAGS definition missing from last patch.Ulrich Drepper
2009-07-30Add test case for ____longjmp_chk vs signal stacks.Ulrich Drepper
2009-07-30Fix x86-64 ____longjmp_chk to handle signal stacks.Ulrich Drepper
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.
