Chandler Carruth f82b0e2d29 Teach InstCombine to nuke a common alloca pattern -- an alloca which has ... GEPs, bit casts, and stores reaching it but no other instructions. These often show up during the iterative processing of the inliner, SROA, and DCE. Once we hit this point, we can completely remove the alloca. These were actually showing up in the final, fully optimized code in a bunch of inliner tests I've been working on, and notably they show up after LLVM finishes optimizing away all function calls involved in hash_combine(a, b). llvm-svn: 154285		2012-04-08 14:36:56 +00:00
