* avcodec/x86/videodsp: Remove obsolete MMX, 3dnow, SSE functionsAndreas Rheinhardt2022-06-221-71/+0
| | | | | | | | | | x64 always has MMX, MMXEXT, SSE and SSE2 and this means that some functions for MMX, MMXEXT, SSE and 3dnow are always overridden by other functions (unless one e.g. explicitly disables SSE2). So given that the only systems which benefit from these functions are truely ancient 32bit x86s they are removed. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.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>
