Detailed Description

Intrinsic Namespace - This namespace contains an enum with a value for every intrinsic/builtin function known by LLVM. These enum values are returned by Function::getIntrinsicID().

AttributeSet llvm::Intrinsic::getAttributes	(	LLVMContext &	C,
		ID	id
	)

Intrinsic::getAttributes(ID) - Return the attributes for an intrinsic.

Function * llvm::Intrinsic::getDeclaration	(	Module *	M,
		ID	id,
		ArrayRef< Type * >	Tys = None
	)

Intrinsic::getDeclaration(M, ID) - Create or insert an LLVM Function declaration for an intrinsic, and return it.

The Tys parameter is for intrinsics with overloaded types (e.g., those using iAny, fAny, vAny, or iPTRAny). For a declaration of an overloaded intrinsic, Tys must provide exactly one type for each overloaded type in the intrinsic.
