Manman Ren 1a710fdde1 BranchProb: modify the definition of an edge in BranchProbabilityInfo to handle ... the case of multiple edges from one block to another. A simple example is a switch statement with multiple values to the same destination. The definition of an edge is modified from a pair of blocks to a pair of PredBlock and an index into the successors. Also set the weight correctly when building SelectionDAG from LLVM IR, especially when converting a Switch. IntegersSubsetMapping is updated to calculate the weight for each cluster. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@162572 91177308-0d34-0410-b5e6-96231b3b80d8		2012-08-24 18:14:27 +00:00
