◆ getFunctionTy()

std::pair< FunctionType *, AttributeList > RuntimeLibcallsInfo::getFunctionTy	(	LLVMContext &	Ctx,
		const Triple &	TT,
		const DataLayout &	DL,
		RTLIB::LibcallImpl	LibcallImpl ) const

Returns: the function type and attributes for the LibcallImpl, depending on the target TT. If the function has incomplete type information, return nullptr for the function type.

◆ lookupLibcallImplName()

LLVM_ABI iota_range< RTLIB::LibcallImpl > llvm::RTLIB::RuntimeLibcallsInfo::lookupLibcallImplName ( StringRef Name )

inlinestatic

Check if a function name is a recognized runtime call of any kind.

This does not consider if this call is available for any current compilation, just that it is a known call somewhere. This returns the set of all LibcallImpls which match the name; multiple implementations with the same name may exist but differ in interpretation based on the target context.
