SDValue PIC16TargetLowering::LowerOperation	(	SDValue	Op,
		SelectionDAG &	DAG
	)			[virtual]

LowerOperation - This callback is invoked for operations that are unsupported by the target, which are registered to use 'custom' lowering, and whose defined values are all legal. If the target has no operations that require custom lowering, it need not implement this. The default implementation of this aborts.

void PIC16TargetLowering::ReplaceNodeResults	(	SDNode *	N,
		SmallVectorImpl< SDValue > &	Results,
		SelectionDAG &	DAG
	)			[virtual]

ReplaceNodeResults - This callback is invoked when a node result type is illegal for the target, and the operation was registered to use 'custom' lowering for that result type. The target places new result values for the node in Results (their number and types must exactly match those of the original return values of the node), or leaves Results empty, which indicates that the node is not to be custom lowered after all.

If the target has no operations that require custom lowering, it need not implement this. The default implementation aborts.

void PIC16TargetLowering::LowerOperationWrapper	(	SDNode *	N,
		SmallVectorImpl< SDValue > &	Results,
		SelectionDAG &	DAG
	)			[virtual]

LowerOperationWrapper - This callback is invoked by the type legalizer to legalize nodes with an illegal operand type but legal result types. It replaces the LowerOperation callback in the type Legalizer. The reason we can not do away with LowerOperation entirely is that LegalizeDAG isn't yet ready to use this callback. TODO: Consider merging with ReplaceNodeResults. The target places new result values for the node in Results (their number and types must exactly match those of the original return values of the node), or leaves Results empty, which indicates that the node is not to be custom lowered after all. The default implementation calls LowerOperation.

PerformDAGCombine - This method will be invoked for all target nodes and for any target-independent nodes that the target has registered with invoke it for.

The semantics are as follows: Return Value: SDValue.Val == 0 - No change was made SDValue.Val == N - N was replaced, is dead, and is already handled. otherwise - N should be replaced by the returned Operand.

In addition, methods provided by DAGCombinerInfo may be used to perform more complex transformations.
