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.
