Merge from mainline. Move the code that adds the DeadMachineInstructionElimPass from target-independent code to target-specific code. This prevents it from running on targets that aren't using fast-isel. In addition to saving compile time, this addresses the problem that not all targets are prepared for it. In order to use this pass, all instructions must declare all their fixed uses and defs of physical registers. git-svn-id: https://llvm.org/svn/llvm-project/llvm/branches/release_24@58425 91177308-0d34-0410-b5e6-96231b3b80d8 Tanya Lattner 10 years ago
