[PATCH] D15489: Use getEdgeProbability() instead of getEdgeWeight() in BFI and remove getEdgeWeight() interfaces from MBPI.

[Dehao Chen via llvm-commits]

danielcdh added a comment.

For the following CFG:

BB1(weight:100)
BB2(weight:1000)
BB3(weight:100)

BB1->BB2(probability: 0%)
BB1->BB3(probability: 100%)
BB2->BB2(probability: 100%)
BB2->BB3(probability: 0%)

Is there a way we can rebuild BB weights from probability?
