Richard Biener <rguenth at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |segher at gcc dot gnu.org --- Comment #2 from Richard Biener <rguenth at gcc dot gnu.org> --- But it looks like x86 has exactly patterns like this - but in this case I guess combine won't ever try this because hardregs are invovled (not sure if it ever tries to "simplify" the three-set into the parallel two-set variant)
