--- Comment #9 from Richard Biener <rguenth at gcc dot gnu.org> --- Btw, as of coalescing I think the only coalescing we should do at out-of-SSA time is coalescing to avoid copies on edges (aka for PHIs and abnormals), the rest should be left to the RA (OTOH we're going to flood early RTL with a lot more pseudos that way, possibly increasing compile-time in DF).
