Hal Finkel 64fa501b10 Apply the InstCombine fptrunc sqrt optimization to llvm.sqrt ... InstCombine, in visitFPTrunc, applies the following optimization to sqrt calls: (fptrunc (sqrt (fpext x))) -> (sqrtf x) but does not apply the same optimization to llvm.sqrt. This is a problem because, to enable vectorization, Clang generates llvm.sqrt instead of sqrt in fast-math mode, and because this optimization is being applied to sqrt and not applied to llvm.sqrt, sometimes the fast-math code is slower. This change makes InstCombine apply this optimization to llvm.sqrt as well. This fixes the specific problem in PR17758, although the same underlying issue (optimizations applied to libcalls are not applied to intrinsics) exists for other optimizations in SimplifyLibCalls. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@194935 91177308-0d34-0410-b5e6-96231b3b80d8		2013-11-16 21:29:08 +00:00

SimplifyCFG	FoldBranchToCommonDest merges branches into a single branch with or/and of the condition. It has a heuristics for estimating when some of the dependencies are processed by out-of-order processors. This patch adds another rule to the heuristics that says that if the "BonusInstruction" that we speculatively execute is used by the condition of the second branch then it is okay to hoist it. This change exposes more opportunities for other passes to transform the code. It does not matter that much that we if-convert the code because the selectiondag builder splits or/and branches into multiple branches when profitable.	2013-11-12 22:37:16 +00:00
