2023-07-10support framework for RunTime Cpu DetectionWang Chen
Just add related code about RTCD to setup the framework. Have not support the actual runtime detection, and I have not understood how RTCD works, FIXME. More analysis please refer to https://github.com/aosp-riscv/libvpx/issues/8#issuecomment-1627896402. Signed-off-by: Wang Chen <wangchen20@iscas.ac.cn> Co-authored-by: sun min <sunmin89@outlook.com>

2019-10-17Fix AVX-512 capability detectionBirk Magnussen
When Checking for AVX Support, only the CPU's Capabilities and YMM Register support by the OS were queried. In case of AVX-512, that is insufficient, and ZMM Register support by the OS needs querying, otherwise the OS will raise an Illegal Operation Exception if the CPU is capable of AVX-512 but the OS is not.

2018-12-21Improve accuracy of benchmarkingelliottk
For small code regions, readtsc can give inaccurate results because it does not account for out-of-order execution. Add x86_tsc_start and x86_tsc_end that account for this, according to the white paper at https://www.intel.com/content/dam/www/public/us/en/documents/white-papers/ia-32-ia-64-benchmark-code-execution-paper.pdf Using x86_tsc_start/end will also add in several more instructions; I imagine this is negligible.

2018-03-23Restore emms usage on x86_64 after 726b021a12c1bMartin Storsjo
Even on x86_64, emms has to be called if the x87 state has been clobbered - the calling code (either within libvpx or in a caller outside of libvpx) may be using the x87 instructions, even though use of them isn't all that common on x86_64. This fixes builds with clang for mingw/x86_64. Change-Id: I1f6072835590b862bad156f17331ba65c813ddd9
2018-03-23Revert "remove fldcw/fstcw from Win64 builds"Johann Koenig
This reverts commit 60a3cb9ad840377d46286bfd703c30a4a4ee56e2. Reason for revert: x87 instruction usage might not be as clear cut as I would like. At the very least, llvm mingw builds appear to having issues with emms.
