Detailed Description

HLVM AST Abstract Pass.

This class provides an abstract interface to Pass execution. This class is meant to be subclassed and the various "handle" methods overriden to gain access to the information in the AST.

Member Enumeration Documentation

enum InterestKinds

Or these together and pass to the constructor to indicate which kinds of things you are interested in.
Enumerator:

All_Interest Pass is interested in everything.

Block_Interest Pass is interested in Blocks.

Operator_Interest Pass is interested in Operators.

Function_Interest Pass is interested in Functions.

Program_Interest Pass is interested in Programs.

Type_Interest Pass is interested in Types.

Variable_Interest Pass is interested in Variables.

Definition at line 49 of file Pass.h.

enum TraversalKinds

Specifies the kinds of traversals that a pass can request. The PassManager always walks the tree in a depth-first search (DFS) and it can call the pass either when it arrives at the node (preorder) on the way down, or when it leaves the node (postorder) on the way up. A pass can also specify that it wants both pre-order and post-order traversal.
Enumerator:

NoTraversal Pass doesn't want to be called!

PreOrderTraversal Call pass on the way down the DFS walk.

PostOrderTraversal Call pass on the way up the DFS walk.

PreAndPostOrderTraversal Call pass on both the way down and up.

Member Function Documentation

virtual void handle ( Node * n,

TraversalKinds mode

) [pure virtual]

Handle any kind of node. Subclasses should override this; the default implementation does nothing. This handler is only called if the interest is set to 0 (interested in everything). It is left to the subclass to disambiguate the Node.

void handleInitialize ( AST * tree ) [virtual]

Handle initialization. This is called before any other handle method is called. Default implementation does nothing
Definition at line 229 of file Pass.cpp.

void handleTerminate ( ) [virtual]

Handle termination. This is called after all other handle methods are called. Default implementation does nothing
Definition at line 234 of file Pass.cpp.
