constraint.

cb4f12466b imdct/x86: Use "s->mdct_size" instead of "1 << s->mdct_bits".
It generates smaller cleaner code.

78b5c97d3e Convert ff_imdct_half_sse() to yasm.
This is to avoid split asm sections that attempt to preserve some
registers between sections.

disabled.

b250f9c66d Change semantic of CONFIG_*, HAVE_* and ARCH_*.
They are now always defined to either 0 or 1.

a6493a8fbd Rename libavcodec/i386/ --> libavcodec/x86/.
It contains optimizations that are not specific to i386 and
libavutil uses this naming scheme already.
