Chris Lattner 8ec1830a01 Teach basicaa that memset's modref set is at worst "mod" and never ... contains "ref". Enhance DSE to use a modref query instead of a store-specific hack to generalize the "ignore may-alias stores" optimization to handle memset and memcpy. llvm-svn: 120368		2010-11-30 00:28:45 +00:00
