Functions
std::optional< RoundingMode >	llvm::convertStrToRoundingMode (StringRef)
	Returns a valid RoundingMode enumerator when given a string that is valid as input in constrained intrinsic rounding mode metadata.
std::optional< StringRef >	llvm::convertRoundingModeToStr (RoundingMode)
	For any RoundingMode enumerator, returns a string valid as input in constrained intrinsic rounding mode metadata.
std::optional< fp::ExceptionBehavior >	llvm::convertStrToExceptionBehavior (StringRef)
	Returns a valid ExceptionBehavior enumerator when given a string valid as input in constrained intrinsic exception behavior metadata.
std::optional< StringRef >	llvm::convertExceptionBehaviorToStr (fp::ExceptionBehavior)
	For any ExceptionBehavior enumerator, returns a string valid as input in constrained intrinsic exception behavior metadata.
Intrinsic::ID	llvm::getConstrainedIntrinsicID (const Instruction &Instr)
	Returns constrained intrinsic id to represent the given instruction in strictfp function.
