2013-10-24avcodec/x86/videodsp: Properly mark sse2 instructions in emulated_edge_mc ↵Ronald S. Bultje
x86 simd 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.

2013-10-07x86inc: Utilize the shadow space on 64-bit WindowsHenrik Gramner
Store XMM6 and XMM7 in the shadow space in functions that clobbers them. This way we don't have to adjust the stack pointer as often, reducing the number of instructions as well as code size. Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>

2013-10-05x86: dsputil: Separate ff_add_hfyu_median_prediction_cmov from dsputil_mmxDiego Biurrun
The function does not depend on MMX and compilation without MMX enabled fails if the function is compiled conditional on MMX availability.

2013-09-29Rewrite emu_edge functions to have separate src/dst_stride arguments.Ronald S. Bultje
This allows supporting files for which the image stride is smaller than the max. block size + number of subpel mc taps, e.g. a 64x64 VP9 file or a 16x16 VP8 file with -fflags +emu_edge.

Most of our VP56 optimizations are VP6-only and will stay that way. So avoid compiling them for VP5-only builds.
