Jakob Stoklund Olesen bd6f44a3a2 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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@157101 91177308-0d34-0410-b5e6-96231b3b80d8		2012-05-19 05:25:50 +00:00
