Allow a BlockFrequency to be divided by a non-zero BranchProbability with saturating arithmetic. This will be used to compute the frequency of a loop header given the probability of leaving the loop. Our long division algorithm already saturates on overflow, so that was a freebie. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@185184 91177308-0d34-0410-b5e6-96231b3b80d8 |
