OK, not really. We don't want to reintroduce the old rewriter hacks. This patch extracts virtual register rewriting as a separate pass that runs after the register allocator. This is possible now that CodeGen/Passes.cpp can configure the full optimizing register allocator pipeline. The rewriter pass uses register assignments in VirtRegMap to rewrite virtual registers to physical registers, and it inserts kill flags based on live intervals. These finalization steps are the same for the optimizing register allocators: RABasic, RAGreedy, and PBQP. llvm-svn: 158244
