* Fix ff_imdct_calc_sse() on gcc-4.6Alex Converse2011-02-041-4/+3
| | | | | | | | Gcc 4.6 only preserves the first value when using an array with an "m" constraint. Signed-off-by: Mans Rullgard <mans@mansr.com> (cherry picked from commit 770c410fbb8e1b87ce8ad7f3d7eddaa55e2b8295)

* imdct/x86: Use "s->mdct_size" instead of "1 << s->mdct_bits".Alex Converse2010-08-231-1/+1
| | | | | | It generates smaller cleaner code. Originally committed as revision 24887 to svn://svn.ffmpeg.org/ffmpeg/trunk

| | | | | | | This is to avoid split asm sections that attempt to preserve some registers between sections. Originally committed as revision 24869 to svn://svn.ffmpeg.org/ffmpeg/trunk
