Comment:
PPC input.c coverage now exceeds no vsx cpu. Speedups 2-12x, usually in
line with no vsx cpu. Some functions got speed less than cpu, because it
is impossible to vectorize them correctly(For example palToUV, palToY)I
commented on them. Some functions got speed equivalent no vsx cpu(For
example planar_rgb16_to_a)
Sorry for accidentally closing the ticket. As the reporter, you should
