--- Comment #9 from avieira at gcc dot gnu.org --- Hmm I was seeing the change in opus_ifft but that does look like different codegen :/ I might not be looking at the right thing. That transformation looks definitely wrong though as the selection selects 3 values from the first vector (which is the result of the plus), and the fneg would negate 2 values right?
