[llvm-commits] Machine Branch Probability Info

[Jakub Staszak]

Hello,

This patch introduces MachineBranchProbabilityInfo class, which has similar API to BranchProbabilityInfo (except setEdgeWeight which is not available here). Branch Weights are keep in MachineBasicBlock. They have the same order (and length) as Successors vector. You can turn off this analysis using -use-mbpi=false. Comments are welcome.

Thanks!
