Michael Liao b9e302f3ca [SimplifyCFG] Revise common code sinking ... - Fix the case where more than 1 common instructions derived from the same operand cannot be sunk. When a pair of value has more than 1 derived values in both branches, only 1 derived value could be sunk. - Replace BB1 -> (BB2, PN) map with joint value map, i.e. map of (BB1, BB2) -> PN, which is more accurate to track common ops. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@224757 91177308-0d34-0410-b5e6-96231b3b80d8		2014-12-23 08:26:55 +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
