Detailed Description Procedure definition. This class represents a procedure (or function) definition. The definition consists of a declarations (which gives the name and interface of the procedure) and the procedure body. The NodeType is Proc. Definition at line 1329 of file ast.h. Constructor & Destructor Documentation procNode::procNode (  declNode *    decl, blockNode *    body, const Coord    coord = Coord::Unknown )    Create a new procedure. Parameters: decl  the procedure declaration (always type funcNode ) body  the code of the procedure body coord  the location of the construct in the source file. Definition at line 48 of file procnode.cc. References Proc. Referenced by clone(). procNode::procNode (  bool    old_style, declNode *    decl )    Create a procedure during parsing.

Warning: Do not use the destructors to delete AST nodes. Instead, rely on the node garbage collector. Definition at line 467 of file procnode.cc. Member Function Documentation int procNode::alloc_stack_local (  declNode *    decl )    Allocate stack space for a local declaration. Returns the assigned stack location, and also sets this information into the declNode. If a particular size is required, pass that size, otherwise pass zero. If a size is specified, it is assumed that the alignment is the same as the size. Definition at line 434 of file procnode.cc.

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.

Referenced by init_flowproblem_walker::at_proc(), returnNode::dataflow(), and dataflow(). typeNode * procNode::base_type (  bool    TdefIndir )  const [virtual]   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. Parameters: TdefIndir  pass true to follow typedefs to their definitions. Reimplemented from Node.

Node * procNode::change (  Changer &    the_changer, bool    redispatch = false )  [virtual]   Dispatch a Changer. This abstract method works much the walker, but allows the tree to be changed.

This is not a "deep" clone, so be careful. For a deep clone, use the ref_clone_changer class. Returns: a shallow copy of the node (no subtrees are copied). Implements Node. Definition at line 1613 of file ast.h. References procNode(). void Node::coord (  const Coord    coord )  [inline, inherited]   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. Parameters: coord  the new location. Definition at line 245 of file ast.h. Coord Node::coord (    )  const [inline, inherited]   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. Returns: the Coord structure indicating where the node came from in the source file. Definition at line 232 of file ast.h.

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. Returns: the typeNode pointer on the node. Reimplemented in declNode, typeNode, exprNode, and operandNode. Definition at line 344 of file ast.h. Referenced by tree_visitor::at_block(), ReturnDismantle::at_return(), asm_gen_walker::doCallerSave(), and briggs_reg_alloc::interfere(). void procNode::visit (  Visitor *    the_visitor )  [virtual]   Dispatch a Visitor. This abstract method is the entry point for the visitor design pattern. Each node subclass defines a visit() method that calls the appropriate at_ method in the visitor. For more information see the Visitor documentation. Parameters: the_visitor  the specific Visitor object to use. Implements Node. Definition at line 306 of file procnode.cc. References Visitor::at_proc(). void procNode::walk (  Walker &    the_walker )  [virtual]   Dispatch a Walker. This abstract method works much like the visitor, but instead walks the entire underlying subtree calling the appropriate at_ method at each node. For more information see the Walker documentation. Parameters: the_walker  the specific Walker object to use. Implements Node. Definition at line 311 of file procnode.cc.

The last stack location that was allocated to a local variable for this procedure. This is used to implement the stack_alloc_local routine in this class. We are storing the last allocated location because we assume the stack grows down, so we need to know where the last thing we allocated went, in order to put the next thing below it. The next thing will have its own size and alignment requirements, so we have to just wait until we encounter it to know where it will go. Definition at line 1372 of file ast.h.
