Detailed Description

Statement.

This class provides a base class for all statement nodes.

The NodeType is determined by the subclass.

---

Constructor & Destructor Documentation

stmtNode::stmtNode (  NodeType    typ, const Coord    coord )

Create a new statement. The new statement has the given NodeType. This constructor is only called by the statement subclasses. Parameters: typ  the kind of statement coord  the location of the construct in the source file.

stmtNode::~stmtNode (    )  [virtual]

Destroy a stmtNode. Warning: Do not use the destructors to delete AST nodes. Instead, rely on the node garbage collector.

Member Function Documentation

void stmtNode::at_exit (  FlowVal *    ae )  [inline]

Reimplemented in basicblockNode.

FlowVal* stmtNode::at_exit (    )  const [inline]

Reimplemented in basicblockNode.

string& stmtNode::comment (    )  [inline]

void stmtNode::output (  output_context &    ct, Node *    parent )  [virtual]

Generate C code. Each subclass overrides this method to define how to produce the output C code. To use this method, pass an output_context and a null parent. Parameters: ct  the output context which describes the formatting. par  the parent node (or null, if at the top of a subtree). Reimplemented from Node.

void stmtNode::output_comment (  output_context &    ct )

virtual void stmtNode::output_stmt (  output_context &    ct, Node *    parent )  [pure virtual]

Output a statement. Reimplemented in blockNode, exprstmtNode, labelNode, caseNode, ifNode, switchNode, whileNode, doNode, forNode, gotoNode, continueNode, breakNode, returnNode, attribNode, and metastmtNode.

text_list& stmtNode::pragmas (    )  [inline]

---

Member Data Documentation

FlowVal* stmtNode::_at_exit [private]

Dataflow analysis exit value. Reimplemented in basicblockNode.

string stmtNode::_comment [private]

Comment. Each statement may have a comment string associated with it. If the string is non-empty, then the C code generator will output the comment right before the statement. The generator provides the comment delimiters automatically, so there is no need to put them in the string.

text_list stmtNode::_pragmas [private]

Pragmas. This list will contain any pragmas that precede the given statement. During parsing, they are collected into the CBZ::pragmas list and then placed here in the stmtNode constructor.
