Michael Ilseman 09ee250e72 Added a slew of SimplifyInstruction floating-point optimizations, many of which take advantage of fast-math flags. Test cases included. ... fsub X, +0 ==> X fsub X, -0 ==> X, when we know X is not -0 fsub +/-0.0, (fsub -0.0, X) ==> X fsub nsz +/-0.0, (fsub +/-0.0, X) ==> X fsub nnan ninf X, X ==> 0.0 fadd nsz X, 0 ==> X fadd [nnan ninf] X, (fsub [nnan ninf] 0, X) ==> 0 where nnan and ninf have to occur at least once somewhere in this expression fmul X, 1.0 ==> X git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@169940 91177308-0d34-0410-b5e6-96231b3b80d8		2012-12-12 00:27:46 +00:00
