Janne Grunau	5c1c6e8226	dca: include dcadsp.h in {arm,x86}/dca.h for checkheaders	11 years ago
Janne Grunau	0cffd6fff5	x86: use the inline int8x8_fmul_int32 only if inline SSE2 is availbale Fixes compilation with MSVC. Also does not rely on on earlier config.h include but include it directly.	11 years ago

Christophe Gisquet	5b59a9fc61	x86: dcadsp: implement int8x8_fmul_int32 For the callable function (as opposed to the inline one): C SSE SSE2 SSE4 Win32: 47 42 29 26 Win64: 30 33 25 23 The SSE version is neither compiled nor set for ARCH_X86_64, as the inlinable function takes over.

Ronald S. Bultje	51daafb02e	x86: videodsp: Properly mark sse2 instructions in emulated_edge_mc as such. Should fix crashes or corrupt output on pre-SSE2 CPUs when they were using SSE2-code (e.g. AMD Athlon XP 2400+ or Intel Pentium III) in hfix or hvar single-edge (left/right) extension functions.

Clément Bœsch	cddbfd2a95	x86/lossless_videodsp: simplify and explicit aligned/unaligned flags	11 years ago
Ronald S. Bultje	c9e6325ed9	vp9/x86: use explicit register for relative stack references. Before this patch, we explicitly modify rsp, which isn't necessarily universally acceptable, since the space under the stack pointer might be modified in things like signal handlers. Therefore, use an explicit register to hold the stack pointer relative to the bottom of the stack (i.e. rsp). This will also clear out valgrind errors about the use of uninitialized data that started occurring after the idct16x16/ssse3 optimizations were first merged.	11 years ago
