@ -10,15 +10,15 @@ stuff in the i386 directory or find some other functions in the C source to
optimize, but there aren't many left.
Understanding these overoptimized functions:
As many functions, like the C ones tend to be a bit unreadable currently
because of optimizations it is difficult to understand them (and write
architecture specific versions, or optimize the C functions further) it is
recommended to look at older CVS versions of the interesting files (just use
ViewCVS at http://www1.mplayerhq.hu/cgi-bin/cvsweb.cgi/ffmpeg/?cvsroot=FFMpeg).
Alternatively, look into the other architecture-specific versions in the i386/,
ppc/, alpha/ subdirectories. Even if you don't exactly understand the
instructions, it could help understanding the functions and how they
can be optimized.
