you've got int = expr long int = int if you want to get rid of the copy, you would have to turn it into long int = (long int)expr which is more complicated than simple expression replacement. In your example, the opportunity also only exists *after* the PHIs have been expanded, which means we are no longer in SSA form either, so the copyrename pass isn't applicable. we'd need a new pass/hacks within out-of-ssa, or a post pass on non-ssa trees. Does this actually affect the code generated? I would think the RTL optimizers should be able to handle it. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=23335
