Understanding these overoptimized functions:
13
As many functions, like the C ones tend to be a bit unreadable currently
14
because of optimizations it is difficult to understand them (and write
15
architecture specific versions, or optimize the C functions further) it is
16
recommended to look at older CVS versions of the interesting files (just use
17
ViewCVS at http://www1.mplayerhq.hu/cgi-bin/cvsweb.cgi/ffmpeg/?cvsroot=FFMpeg).
18
Alternatively, look into the other architecture-specific versions in the i386/,
19
ppc/, alpha/ subdirectories. Even if you don't exactly understand the
20
instructions, it could help understanding the functions and how they
21
can be optimized.
