* Remove code without too much effectsUlrich Drepper2011-10-2815-113/+5
| | | | | Some of the AVX-specific code is not giving enough speed-up to justify the extra code.
* Add AVX optimized versions for some x86-64 math functionsUlrich Drepper2011-10-2527-20/+276
|
* Use VEX encoding in inline math functions on x86-64 when possibleUlrich Drepper2011-10-251-48/+138
|
* Cleanup FMA4 patchUlrich Drepper2011-10-2522-1/+26
| | | | | Move the FMA4 code into its own section. Avoid some of the duplication of data resulting from the double use of source files.
* Better DLA_FMSUlrich Drepper2011-10-241-0/+17
| | | | | It's better to use __builtin_fma if it works. Use it for gcc 4.6 and higher. Move the x86-64 dla.h to the correct place.

|
* Provide internal optimizations on x86-64 with SSE4.1Ulrich Drepper2011-10-176-12/+51
| | | | | | | Provide macros so that the internal users can, if possible, directly use the new instructions. Also fix up the mathinline.h header when compiling with SSE4.1 enabled.

|
* Add ceil implementation for 64-bit machines.Ulrich Drepper2009-08-241-0/+17
| | | | | | | 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.
