Jakob Stoklund Olesen 82d77e8145 Run proper recursive dead code elimination during coalescing. ... Dead copies cause problems because they are trivial to coalesce, but removing them gived the live range a dangling end point. This patch enables full dead code elimination which trims live ranges to their uses so end points don't dangle. DCE may erase multiple instructions. Put the pointers in an ErasedInstrs set so we never risk visiting erased instructions in the work list. There isn't supposed to be any dead copies entering RegisterCoalescer, but they do slip by as evidenced by test/CodeGen/X86/coalescer-dce.ll. llvm-svn: 157101		2012-05-19 05:25:50 +00:00
