Constructor & Destructor Documentation

llvm::SDNode::SDNode	(	unsigned	Opc,
		SDVTList	VTs,
		const SDValue *	Ops,
		unsigned	NumOps
	)			[inline, protected]

The constructors that supply DebugLoc explicitly should be preferred for new code.

Definition at line 1354 of file SelectionDAGNodes.h.

References llvm::SDUse::setInitial(), and llvm::SDUse::setUser().

llvm::SDNode::SDNode	(	unsigned	Opc,
		SDVTList	VTs
	)			[inline, protected]

This constructor adds no operands itself; operands can be set later with InitOperands.

Definition at line 1370 of file SelectionDAGNodes.h.

llvm::SDNode::SDNode	(	unsigned	Opc,
		const DebugLoc	dl,
		SDVTList	VTs,
		const SDValue *	Ops,
		unsigned	NumOps
	)			[inline, protected]

The next two constructors specify DebugLoc explicitly; the intent is that they will replace the above two over time, and eventually the ones above can be removed.

Definition at line 1379 of file SelectionDAGNodes.h.

References llvm::SDUse::setInitial(), and llvm::SDUse::setUser().

llvm::SDNode::SDNode	(	unsigned	Opc,
		const DebugLoc	dl,
		SDVTList	VTs
