¶bool ConstantFoldTerminator(
    llvm::BasicBlock* BB,
    bool DeleteDeadConditions = false,
    const llvm::TargetLibraryInfo* TLI = nullptr,
    llvm::DomTreeUpdater* DTU = nullptr)

Description

If a terminator instruction is predicated on a constant value, convert it into an unconditional branch to the constant destination. This is a nontrivial operation because the successors of this basic block must have their PHI nodes updated. Also calls RecursivelyDeleteTriviallyDeadInstructions() on any branch/switch conditions and indirectbr addresses this might make dead if DeleteDeadConditions is true.

Declared at: llvm/include/llvm/Transforms/Utils/Local.h:121

Parameters

llvm::BasicBlock* BB

bool DeleteDeadConditions = false

const llvm::TargetLibraryInfo* TLI = nullptr

llvm::DomTreeUpdater* DTU = nullptr
