| * mpegaudio: replace memcpy by SIMD codeChristophe GISQUET2012-02-151-1/+20
| | | | | | | | | | | | | | | | | | | | | | | | 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>
* | Fix compilation without HAVE_AVX, HAVE_YASM etc.Reimar Döffinger2012-01-141-1/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | 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.
