struct LowerConstantIntrinsicsPass

Declaration

struct LowerConstantIntrinsicsPass : public PassInfoMixin { /* full declaration omitted */ };

Description

A CRTP mix-in to automatically provide informational APIs needed for passes. This provides some boilerplate for types that are passes.

Method Overview

• public LowerConstantIntrinsicsPass()
• public llvm::PreservedAnalyses run(llvm::Function & F, llvm::FunctionAnalysisManager &)

¶llvm::PreservedAnalyses run(
    llvm::Function& F,
    llvm::FunctionAnalysisManager&)

Description

Run the pass over the function. This will lower all remaining 'objectsize' and 'is.constant'` intrinsic calls in this function, even when the argument has no known size or is not a constant respectively. The resulting constant is propagated and conditional branches are resolved where possible. This complements the Instruction Simplification and Instruction Combination passes of the optimized pass chain.

Parameters

llvm::Function& F

llvm::FunctionAnalysisManager&
