James Darnley	c9a51c29fc	yadif: remove an 'm' from the LOAD macro definition Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
James Darnley	1d3b14cac2	yadif: remove repeated check on width The filter already checks that width (and height) are greater than 3. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
James Darnley	0a5814c9ba	yadif: x86 assembly for 9 to 14-bit samples These smaller samples do not need to be unpacked to double words allowing the code to process more pixels every iteration (still 2 in MMX but 6 in SSE2). It also avoids emulating the missing double word instructions on older instruction sets. Like with the previous code for 16-bit samples this has been tested on an Athlon64 and a Core2Quad. Athlon64: 1809275 decicycles in C, 32718 runs, 50 skips 911675 decicycles in mmx, 32727 runs, 41 skips, 2.0x faster 495284 decicycles in sse2, 32747 runs, 21 skips, 3.7x faster Core2Quad: 921363 decicycles in C, 32756 runs, 12 skips 486537 decicycles in mmx, 32764 runs, 4 skips, 1.9x faster 293296 decicycles in sse2, 32759 runs, 9 skips, 3.1x faster 284910 decicycles in ssse3, 32759 runs, 9 skips, 3.2x faster Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago

Daniel Kang	67360ccd51	yadif: x86: fix build for compilers without aligned stack Manually load registers to avoid using 8 registers on x86_32 with compilers that do not align the stack (e.g. MSVC). Signed-off-by: Diego Biurrun <diego@biurrun.de>	12 years ago
