Sanjay Patel a932da8f35 Fix for PR17073 ( http://llvm.org/pr17073 ), simplifycfg illegally hoists an operation in a phi node that can trap. ... This patch adds to an existing loop over phi nodes in SimplifyCondBranchToCondBranch() to check for trapping ops and bails out of the optimization if we find one of those. The test cases verify that trapping ops are not hoisted and non-trapping ops are still optimized as expected. llvm-svn: 212490		2014-07-07 21:19:00 +00:00

common-dest-folding.ll	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
