Matt Arsenault	bdbe8280f2	Add address space mangling to lifetime intrinsics ... In preparation for allowing allocas to have non-0 addrspace. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@299876 91177308-0d34-0410-b5e6-96231b3b80d8	2017-04-10 20:18:21 +00:00
Paul Robinson	16cba6923a	FastISel needs to remove dead code when it bails out. ... When FastISel fails to translate an instruction it hands off code generation to SelectionDAG. Before it does so, it may have generated local value instructions to feed phi nodes in successor blocks. These instructions will then be generated again by SelectionDAG, causing duplication and less efficient code, including extra spill instructions. Patch by Wolfgang Pieb!
