| | | | | | | | None of them are specific to the YASM assembler. (Cherry-picked from libav commit 39e208f4d4756367c7cd2d581847e0c1b8a429c1) Signed-off-by: James Almer <jamrial@gmail.com>

* Revert "x86/videodsp: add emulated_edge_mc_mmxext"Michael Niedermayer2014-06-281-39/+5
| | | | | | | | | | The commit causes minor out of array reads and was mainly intended for future optimizations which turned out not to be meassurably faster. Itself it was just 1 cpu cycle faster Approved-by: jamrial This reverts commit 057d2704e78b52fec357b4fc646c9de37a085413.
* x86/videodsp: add emulated_edge_mc_mmxextJames Almer2014-06-261-5/+39
| | | | | | | | | | | | | | This also changes hfix8_mmx and above to use mmx regs instead of gprs, and makes emulated_edge_mc_sse and emulated_edge_mc_sse2 use mmxext hfix and hvar functions instead of mmx where possible. This is mostly in preparation for an ssse3 version. Signed-off-by: James Almer <jamrial@gmail.com> code is about 1 cpu cycle faster approximately Signed-off-by: Michael Niedermayer <michaelni@gmx.at>
