| | | | | | | | | | | | | | 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

| | | | | | | | | | | | | Fix a nasty miscompilation of 176.gcc on linux/x86 where we synthesized a memset using 16-byte XMM stores, but where the stack realignment code didn't work. Until it does (PR2962) disable use of xmm regs in memcpy and memset formation for linux and other targets with insufficiently aligned stacks. This is part of PR2888 git-svn-id: https://llvm.org/svn/llvm-project/llvm/branches/release_24@58423 91177308-0d34-0410-b5e6-96231b3b80d8
