Justin Bogner 31eaed9c6d Transforms: Don't create bad branch weights when folding a switch ... This avoids creating branch weight metadata of length one when we fold cases into the default of a switch instruction, which was triggering an assert. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@196845 91177308-0d34-0410-b5e6-96231b3b80d8		2013-12-10 00:13:41 +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
