Teach GetNegatedExpression to negate 0-B to B in UnsafeFPMath mode, and visitFSUB to fold 0-B to -B in UnsafeFPMath mode. Also change visitFNEG to use isNegatibleForFree/GetNegatedExpression instead of doing a subset of the same thing manually. This fixes test/CodeGen/X86/negative-sin.ll. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@37842 91177308-0d34-0410-b5e6-96231b3b80d8
