Detailed Description

SelectionDAG class - This is used to represent a portion of an LLVM function in a low-level Data Dependence 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 the SelectionDAG 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.

ComputeNumSignBits - Return the number of times the sign bit of the register is replicated into the other bits. We know that at least 1 bit is always equal to the sign bit (itself), but other cases can give us information. For example, immediately after an "SRA X, 2", we know that the top 3 bits are all equal to each other, so we return 3. Targets can implement the ComputeNumSignBitsForTarget method in the TargetLowering class to allow target nodes to be understood.

SDNode * SelectionDAG::MorphNodeTo	(	SDNode *	N,

MorphNodeTo - This mutates 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 the SDLoc 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.

void SelectionDAG::ReplaceAllUsesWith	(	SDValue	FromN,

ReplaceAllUsesWith - Modify anything using 'From' to use 'To' instead. 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.
