gcc47-pr49621.patch
I believe the bug is in the ppc vector select patterns, comparing a vector mode
reg with const0_rtx in a NE is bound to confuse the middle-end. Both operands
of a comparison should always have either the same mode, or one should be
VOIDmode and the other should have integer or CC mode.
The following patch fixes this, completely untested so far.
