Carl Eugen Hoyos	36904c4c9f	Icc 11.1 still does not align the stack pointer, disable some x264 functions. Originally committed as revision 19454 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Jason Garrett-Glaser	73b02e2460	SSE version of clear_blocks Originally committed as revision 19206 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Jason Garrett-Glaser	4f717c69ed	idct_dc for VC-1/WMV3 decoder; ~11% faster decoding overall. Includes mmx2 asm for the various functions. Note that the actual idct still does not have an x86 SIMD implemtation. For wmv3 files using regular idct, the decoder just falls back to simple_idct, since simple_idct_dc doesn't exist (yet). Originally committed as revision 19204 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Ramiro Polla	74a841af8b	Replace more uses of __attribute__((aligned)) by DECLARE_ALIGNED. Originally committed as revision 19089 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Ramiro Polla	989b7181ac	Use fewer macros in x86-optimized mlpdsp. Fixes compilation on 32-bit llvm which didn't allow a cast in an m operand. Originally committed as revision 19086 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Alexander Strange	2b9969a945	H264: Fix out of bounds reads in SSSE3 MC Reading above src[-2] isn't safe, so move loads and palignr ahead 3 pixels to load starting at the first pixel actually used. Fixes issue941. Originally committed as revision 18999 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Ramiro Polla	7c4c60e520	mlp: Use LABEL_MANGLE() to export label symbols from inside asm block. Originally committed as revision 18935 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Ramiro Polla	5624766d18	MLP DSP functions x86-optimized. 12.59% overall speedup in x86_32 9.98% overall speedup in x86_64 compared to gcc 4.3.3 Originally committed as revision 18903 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
David Conrad	c21c835b8d	avg_ pixel functions need to use (dst+pix+1)>>1 to average with existing pixels, not (dst+pix)>>1. This makes the mmx functions bitexact with the C functions. Originally committed as revision 18527 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago

Reimar Döffinger	d7460a9cac	Mark put_signed_pixels_clamped_mmx output operands as early-clobber because they are. Hopefully fixes some FATE errors, too. Originally committed as revision 18326 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
