Unhappy Why do 3Dnow! idct tests fail on my Athlon


I use FlaskMpeg0.6 and Xmpeg4.2a, DivX4.12 and encode on an
Athlon 1.4Ghz however ALL the 3DNow idct tests fail the
IEEE-1180 tests including MCMAB 3dnow idcts. Is there something
else I am missing to enable 3dnow? I can use the MMX and x87
idcts fine.

Actually, the 3dnow! idct implementation is buggy, and outside idct specs, that's why it fails.
