Comment (by bookmoons):
Hi guys. I have something toward a vectorized hScale8To15_c from
swscale.c. Profiling with callgrind shows it's a little faster than the
unoptimized version, but not as fast as the extant altivec version. Hope
to figure to figure out what's causing the difference and improve it.
Unoptimized - 11,140,574
VSX optimized - 9,670,008
Altivec optimized - 3,511,966
Does this seem like the right direction?
