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
 close it.
