Andrew Trick b2ab2fa524 Inlining and unrolling heuristics should be aware of free truncs. ... We want heuristics to be based on accurate data, but more importantly we don't want llvm to behave randomly. A benign trunc inserted by an upstream pass should not cause a wild swings in optimization level. See PR11034. It's a general problem with threshold-based heuristics, but we can make it less bad. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@140919 91177308-0d34-0410-b5e6-96231b3b80d8		2011-10-01 01:39:05 +00:00
