Philip Reames 46cd55f309 [InstCombine] Extend peephole DSE to handle unordered atomics ... This extends the same line of reasoning used in EarlyCSE w/http://reviews.llvm.org/D15352 to the DSE implementation in InstCombine. Key points: * We only remove unordered or simple stores. * The loads producing values consumed by dead stores don't influence whether the store is dead. Differential Revision: http://reviews.llvm.org/D15354 llvm-svn: 255932		2015-12-17 22:19:27 +00:00
