AST traversal | |
These methods provide a uniform way to traverse the AST without explicitly testing the node types. They are all variations of the visitor design pattern. The input object is an instance of a user-defined subclass of Visitor, Walker or Changer. By overriding virtual methods, the user can define what to do at each kind of node that is encountered. See the C-Breeze documentation for more details. | |

Get the annotations list. This method returns a modifiable reference to the list of annotations on the node. Users can add new annotations, search for annotations, or remove annotations. Users are responsible for ensuring that every element of the annotation list points to a valid annotation. In particular, no element should be NULL.

|
Return the base data type of a node. This method differs from the Node::type() method in two respects. First, it follows some of the simple type inferences. For example, calling it on an idNode will return the type of its declaration. Second, the boolean argument indicates whether or not to follow typedef links.
Reimplemented from Node. Reimplemented in idNode, commaNode, and callNode. Definition at line 69 of file exprnode.cc. References typeNode::base_type(), and exprNode::type(). Referenced by exprstmtNode::base_type(), callNode::base_type(), and operandNode::noncast_type(). |

Clone the input node. This is not a "deep" clone, so be careful. For a deep clone, use the ref_clone_changer class.
Implemented in unitNode, declNode, subdeclNode, procNode, primNode, tdefNode, ptrNode, arrayNode, funcNode, structNode, unionNode, enumNode, suespecNode, constNode, idNode, binaryNode, unaryNode, castNode, commaNode, ternaryNode, callNode, initializerNode, blockNode, basicblockNode, exprstmtNode, labelNode, caseNode, ifNode, switchNode, whileNode, doNode, forNode, gotoNode, continueNode, breakNode, returnNode, attribNode, operandNode, conditiongotoNode, threeAddrNode, textNode, metaexprNode, and metastmtNode. Referenced by ref_clone_changer::at_node(). |

Set the source location. This location should indicate the position in the source text that this Node represents, or Coord::Unknown if it does not represent any node in the source text. It is not common to set the source location of a node. Currently, only the compiler error messages actually make use of it.
|
|
|
Get the source location. The Coord class holds a location in the input source (file, line, position). During parsing, each AST node created records the position of the source text that it represents. However, subsequent phases may create or change nodes, so no guarantee is given about how the source location corresponds to the original source text.

Run the dataflow analyzer. Each subclass overrides this method to define it's semantics for dataflow analysis. It alters the input flow value to reflect the effect of the node within the given flow problem, calling dataflow() on it's subtrees as necessary. See the dataflow analysis documentation for more information.

Constant expression evaluator. This method attempts to evaluate an expression at compile-time. This only yields a meaningful value when the leaves of the given expression are constants, enums, or other compile-time values (e.g., sizeof). The resulting value is stored on each exprNode, in the _value field. Each exprNode sublcass implements this method, calling it recursively when necessary.

Return the node data type. This method returns the C data type of a node. Several different kinds of nodes contain typeNode pointers. This method is just a unified way to access them. It does not attempt to compute the type, it just returns whatever typeNode pointer resides on the node. The subclasses that have types return them, and the others return null.

Usual arithmetic conversions. This method takes two expressions and adds any casts that are necessary to make them compatible for arithmetic operations. It calls typeNode::usual_arithmetic_conversions(), passing the types of the expressions, to determine when the casts are needed.
