Michael Niedermayer	6f3c50f2f9	Negate a few variables, this simplifies the code and makes it 5 cycles faster on pentium dual. Originally committed as revision 16274 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Michael Niedermayer	60c6ba7aea	Simplify ifs(), 8 cpu cycles faster on pentium dual Originally committed as revision 16273 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago

Diego Biurrun	a6493a8fbd	Rename libavcodec/i386/ --> libavcodec/x86/. It contains optimizations that are not specific to i386 and libavutil uses this naming scheme already. Originally committed as revision 16270 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
