¶llvm::Constant* ConstantFoldInstOperands(
    llvm::Instruction* I,
    ArrayRef<llvm::Constant*> Ops,
    const llvm::DataLayout& DL,
    const llvm::TargetLibraryInfo* TLI = nullptr)

Description

ConstantFoldInstOperands - Attempt to constant fold an instruction with the specified operands. If successful, the constant result is returned, if not, null is returned. Note that this function can fail when attempting to fold instructions like loads and stores, which have no constant expression form.

Declared at: llvm/include/llvm/Analysis/ConstantFolding.h:61

Parameters

llvm::Instruction* I

ArrayRef<llvm::Constant*> Ops

const llvm::DataLayout& DL

const llvm::TargetLibraryInfo* TLI = nullptr
