Ganesh Ajjanagadde	0544c95fd6	avcodec/x86/mpegaudiodsp: silence -Wunused-variable on --disable-mmx This silences -Wunused-variable when compiled with --disable-mmx, e.g http://fate.ffmpeg.org/log.cgi?time=20150919094617&log=compile&slot=x86_64-archlinux-gcc-disable-mmx. The alternative of header guards will make it far too ugly. Signed-off-by: Ganesh Ajjanagadde <gajjanagadde@gmail.com> Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	9 years ago

James Almer	fbf98375e4	x86/imdct36: don't build imdct36_float_sse on x86_64 targets There's an SSE2 version as well, and x86_64 guarantees that instruction set is present.

Christophe GISQUET	f3e084909b	mpegaudio: replace memcpy by SIMD code By replacing memcpy with an unrolled loop using the alignment knowledge it has, some speedup can be obtained. Before (gcc 4.6.1): ~400 cycles After: ~370 cycles Overall, around 2% speed increase when decoding a 2400s mp3 to f32le. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	13 years ago
Reimar Döffinger	7a1723086a	Fix compilation without HAVE_AVX, HAVE_YASM etc. At the very least this should fix warnings about unused static functions if one or more of these is not defined. However even compilation might be broken if the compiler does not optimize the function away completely. This actually happens in case of the AVX function, since the function pointer is used in an assignment that is not under an #if and thus probably only optimized away after the function was already marked as used.
