| 2009-08-08 | Remove duplicate NEWS entry. | Ulrich Drepper | 1 | -3/+0 | |

| 2009-08-08 | Support mixed SSE/AVX audit and check AVX only once. | H.J. Lu | 11 | -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. | |||||
| 2009-08-08 | Use PIC only if SHARED is defined. | H.J. Lu | 3 | -0/+36 | |
| For ia32, we can avoid PIC in IFUNC functions in static library. | |||||

| 2009-08-07 | Fix whitespaces in last checkin. | Ulrich Drepper | 1 | -1/+1 | |
| 2009-08-07 | Properly count number of logical processors on Intel CPUs. | H.J. Lu | 2 | -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. | |||||
| 2009-08-07 | Fix sed expression in TAGS command. | Andreas Schwab | 2 | -2/+7 | |
| The backslash-newline pair is interpreted as the beginning of an address regex. | |||||

| 2009-08-04 | Add x86 SSE strlen. | Ulrich Drepper | 4 | -6/+166 | |
| 2009-08-04 | Add x86 32-bit SSE4.2 string functions. | H.J. Lu | 14 | -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. | |||||
| 2009-08-04 | Optimize x86-64 syscall cancellation handling. | Ulrich Drepper | 6 | -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. | |||||
| 2009-08-02 | Remove leftover code from Linux/x86 ____longjmp_chk. | Ulrich Drepper | 1 | -6/+0 | |
| 2009-08-02 | x86/x86-64 now needs <cpuid.h> from gcc. | Ulrich Drepper | 3 | -44/+67 | |
| 2009-08-01 | Remove last trace of bounded pointer handling from ____longjmp_chk on x86-64. | Ulrich Drepper | 1 | -1/+1 | |
| 2009-07-31 | Macro cleanup. | Ulrich Drepper | 2 | -8/+12 | |

| 2009-07-31 | Merge branch 'master' of file:///net/myware66/home/drepper/gnu/libc | Ulrich Drepper | 3 | -117/+59 | |
| 2009-07-31 | Regenerated. | Ulrich Drepper | 1 | -8/+40 | |
| 2009-07-31 | Optimize x86 and x86-64 ____longjmp_chk for Linux. | Ulrich Drepper | 3 | -117/+54 | |
| 2009-07-31 | Fix ____longjmp_chk on x86-64. | Ulrich Drepper | 2 | -2/+7 | |
| After a recent change to fix CFI in ____longjmp_chk the test of the ss_flags used the wrong memory location. | |||||
| 2009-07-31 | Support multiarch for i686. | H.J. Lu | 13 | -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. | |||||
| 2009-07-31 | Fix obstack* on i?86 | Jakub Jelinek | 2 | -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. | |||||
| 2009-07-31 | Remove CHEC_ESP handling from i386 __longjmp. | Ulrich Drepper | 1 | -9/+0 | |
| 2009-07-30 | Whitespace cleanup. | Ulrich Drepper | 1 | -2/+2 | |
| 2009-07-30 | Add sigstack handling to Linux ____longjmp_chk on i386. | Ulrich Drepper | 4 | -61/+156 | |
| All other i386 ports need to provide their own versions. | |||||
| 2009-07-30 | ____longjmp_chk is now OS-specific. | Ulrich Drepper | 3 | -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. | |||||
| 2009-07-30 | Change code a bit to correct CFI. | Ulrich Drepper | 1 | -1/+3 | |
| 2009-07-30 | Optimize ____longjmp_chk for x86-64 a bit. | Ulrich Drepper | 1 | -5/+3 | |
| 2009-07-30 | Add CFLAGS definition missing from last patch. | Ulrich Drepper | 1 | -0/+2 | |
| 2009-07-30 | Add test case for ____longjmp_chk vs signal stacks. | Ulrich Drepper | 3 | -1/+119 | |
| 2009-07-30 | Fix x86-64 ____longjmp_chk to handle signal stacks. | Ulrich Drepper | 3 | -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. | |||||
| 2009-07-30 | Stop backtrace when we make no more progress. | Ulrich Drepper | 2 | -2/+13 | |
| 2009-07-29 | Add support for x86-64 fma instruction. | Ulrich Drepper | 6 | -2/+110 | |
| Use it to implement fma and fmaf, if possible. | |||||
