class LazyBranchProbabilityInfoPass::LazyBranchProbabilityInfo

Declaration

class LazyBranchProbabilityInfoPass::LazyBranchProbabilityInfo { /* full declaration omitted */ };

Description

Wraps a BPI to allow lazy computation of the branch probabilities. A pass that only conditionally uses BPI can uncondtionally require the analysis without paying for the overhead if BPI doesn't end up being used.
