Detailed Description

This is used to represent a portion of an LLVM function in a low-level DataDependence DAG representation suitable for instruction selection.

This DAG is constructed as the first step of instruction selection in order to allow implementation of machine specific optimizations and code simplifications.

The representation used by theSelectionDAG is a target-independent representation, which has some similarities to the GCC RTL representation, but is significantly more simple, powerful, and is a graph form instead of a linear form.

◆ LegalizeOp()

bool SelectionDAG::LegalizeOp	(	SDNode *	N,

	)

Transforms aSelectionDAG node and any operands to it into a node that is compatible with the target instruction selector, as indicated by theTargetLowering object.

Returns: true ifN is a valid, legal node after calling this.

This essentially runs a single recursive walk of theLegalize process over the given node (and its operands). This can be used to incrementally legalize the DAG. All of the nodes which are directly replaced, potentially including N, are added to the output parameterUpdatedNodes so that the delta to the DAG can be understood by the caller.

When this returns false, N has been legalized in a way that make the pointer passed in no longer valid. It may have even been deleted from the DAG, and so it shouldn't be used further. When this returns true, the N passed in is a legal node, and can be immediately processed as such. This may still have done some work on the DAG, and will still populate UpdatedNodes with any new nodes replacing those originally in the DAG.

◆ MorphNodeTo()

Thismutates the specified node to have the specified return type, opcode, and operands.

MorphNodeTo - Thismutates the specified node to have the specified return type, opcode, and operands.

Note that MorphNodeTo returns the resultant node. If there is already a node of the specified opcode and operands, it returns that node instead of the current one. Note that theSDLoc need not be the same.

Using MorphNodeTo is faster than creating a new node and swapping it in with ReplaceAllUsesWith both because it often avoids allocating a new node, and because it doesn't require CSE recalculation for any of the node's users.

However, note that MorphNodeTo recursively deletes dead nodes from the DAG. As a consequence it isn't appropriate to use from within the DAG combiner or the legalizer which maintain worklists that would need to be updated when deleting things.

This can cause recursive merging of nodes in the DAG.Use the first version if 'From' is known to have a single result, use the second if you have two nodes with identical results (or if 'To' has a superset of the results of 'From'), use the third otherwise.

These methods all take an optional UpdateListener, which (if not null) is informed about nodes that are deleted and modified due to recursive changes in the dag.

These functions only replace all existing uses. It's possible that as these replacements are being performed, CSE may cause the From node to be given new uses. These new uses of From are left in place, and not automatically transferred to To.

This can cause recursive merging of nodes in the DAG.

This version assumes From has a single result value.

Mutate the specified node in-place to have the specified operands.

UpdateNodeOperands -Mutate the specified node in-place to have the specified operands.

If the resultant node already exists in the DAG, this does not modify the specified node, instead it returns the node that already exists. If the resultant node does not exist in the DAG, the input node is returned. As a degenerate case, if you specify the same input operands as the node already has, the input node is returned.

◆ NewNodesMustHaveLegalTypes

bool llvm::SelectionDAG::NewNodesMustHaveLegalTypes = false

When true, additional steps are taken to ensure thatgetConstant() and similar functions return DAG nodes that have legal types.

This is important after type legalization since any illegally typed nodes generated after this point will not experience type legalization.
