Description

Attempt to constant fold a compare instruction (icmp/fcmp) with the specified operands. If it fails, it returns a constant expression of the specified operands. Denormal inputs may be flushed based on the denormal handling mode.

Declared at: llvm/include/llvm/Analysis/ConstantFolding.h:74

Parameters

unsigned int Predicate

llvm::Constant* LHS

llvm::Constant* RHS

const llvm::DataLayout& DL

const llvm::TargetLibraryInfo* TLI = nullptr

const llvm::Instruction* I = nullptr
