Loren Merritt	1e4ecf26f5	ff_fft_calc_3dn/3dn2/sse: convert intrinsics to inline asm. 2.5% faster fft, 0.5% faster vorbis. Originally committed as revision 6023 to svn://svn.ffmpeg.org/ffmpeg/trunk	19 years ago
Loren Merritt	60ae06e77e	r5954 broke fft on cpus with 3dnow but without mm3dnow.h Originally committed as revision 5974 to svn://svn.ffmpeg.org/ffmpeg/trunk	19 years ago
Loren Merritt	bcfa3e58ee	3dnow2 implementation of imdct. 6% faster vorbis and wma. Originally committed as revision 5954 to svn://svn.ffmpeg.org/ffmpeg/trunk	19 years ago
Benjamin Larsson	7943355485	ff_fft_init now double checks that the system has mm3dnow.h before checking if the cpu can do 3dnow at all. This bug caused amd cpu's without sse to not have a working fft function. Ie no wma, cook or vorbis decoder. Originally committed as revision 5570 to svn://svn.ffmpeg.org/ffmpeg/trunk	19 years ago
