Marc Glisse <glisse at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |glisse at gcc dot gnu.org --- Comment #5 from Marc Glisse <glisse at gcc dot gnu.org> 2012-05-07 14:52:46 UTC --- Actually, why isn't constant propagation happening for the example in comment #1? simplify-rtx.c contains code to that effect, it might just need a little tweaking... (yes, I know the original report is probably interested in non-constant operands)
