Member Function Documentation

◆ getDeclaration()

virtual Function* llvm::TargetIntrinsicInfo::getDeclaration	(	Module *	M,
		unsigned	ID,
		Type **	Tys = `nullptr`,
		unsigned	numTys = `0`
	)		const

pure virtual

Create or insert an LLVM Function declaration for an intrinsic, and return it.

The Tys and numTys are for intrinsics with overloaded types. See above for more information.

Implemented in llvm::AMDGPUIntrinsicInfo.

Referenced by lookupName().

◆ getIntrinsicID()

unsigned TargetIntrinsicInfo::getIntrinsicID ( const Function * F ) const

virtual

Return the target intrinsic ID of a function, or 0.

Definition at line 25 of file TargetIntrinsicInfo.cpp.

◆ getName()

virtual std::string llvm::TargetIntrinsicInfo::getName	(	unsigned	IID,
		Type **	Tys = `nullptr`,
		unsigned	numTys = `0`
	)		const

pure virtual

Return the name of a target intrinsic, e.g.

"llvm.bfin.ssync". The Tys and numTys parameters are for intrinsics with overloaded types (e.g., those using iAny or fAny). For a declaration for an overloaded intrinsic, Tys should point to an array of numTys pointers to Type, and must provide exactly one type for each overloaded type in the intrinsic.

Implemented in llvm::AMDGPUIntrinsicInfo.
