[Bug target/28691] missed optimization, redundant scalar SSE comparisons



------- Comment #3 from pinskia at gcc dot gnu dot org  2006-08-11 06:25 -------
Hmm, now it is because the order int the compares are different:
  418f01:       comiss %xmm0,%xmm1
  418f04:       seta   %al
  418f07:       comiss %xmm1,%xmm0

see how the first is xmm0, xmm1 While the second is xmm1, xmm0.

Can you file a seperate bug with the source to that function (and make sure it
compiles on its own) because that is a different bug as far as I can tell?
