Lang Hames d693cafcfb Add DAG-combines for aggressive FMA formation. ... This patch adds DAG combines to form FMAs from pairs of FADD + FMUL or FSUB + FMUL. The combines are performed when: (a) Either AllowExcessFPPrecision option (-enable-excess-fp-precision for llc) OR UnsafeFPMath option (-enable-unsafe-fp-math) are set, and (b) TargetLoweringInfo::isFMAFasterThanMulAndAdd(VT) is true for the type of the FADD/FSUB, and (c) The FMUL only has one user (the FADD/FSUB). If your target has fast FMA instructions you can make use of these combines by overriding TargetLoweringInfo::isFMAFasterThanMulAndAdd(VT) to return true for types supported by your FMA instruction, and adding patterns to match ISD::FMA to your FMA instructions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@158757 91177308-0d34-0410-b5e6-96231b3b80d8		2012-06-19 22:51:23 +00:00
