| * Handle AVX saving on x86-64 in interrupted smbol lookups.Ulrich Drepper2009-08-251-1/+0
| | | | | | | | | | | | | | | | | | If a signal arrived during a symbol lookup and the signal handler also required a symbol lookup, the end of the lookup in the signal handler reset the flag whether restoring AVX/SSE registers is needed. Resetting means in this case that the tail part of the outer lookup code will try to restore the registers and this can fail miserably. We now restore to the previous value which makes nesting calls possible.
| * Add ceil implementation for 64-bit machines.Ulrich Drepper2009-08-242-0/+84
| | | | | | | | | | | | | | On 64-bit machines we should not split doubles into two 32 bit integer and handle the words separately. We have wide registers. This patch implements a 64-bit ceil version. Ideally all other functions will be converted over time.

| * Support mixed SSE/AVX audit and check AVX only once.H.J. Lu2009-08-082-237/+276
| | | | | | | | | | | | | | | | | | | | 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.

| * Properly count number of logical processors on Intel CPUs.H.J. Lu2009-08-071-4/+38
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| * Add x86 32-bit SSE4.2 string functions.H.J. Lu2009-08-0413-4/+219
| | | | | | | | | | | | 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.

| | | | | | | | | | | | | | 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.
