Description

If this basic block is ONLY a setcc and a branch, and if a predecessor branches to us and one of our successors, fold the setcc into the predecessor and use logical operations to pick the right destination.

Parameters

llvm::BranchInst* BI

llvm::DomTreeUpdater* DTU = nullptr

llvm::MemorySSAUpdater* MSSAU = nullptr
