Type comparison operators
These operators are used to compare types. They recursively descend the compound types and verify the structure. There are several different variations, depending on the level of strictness. In all cases, typedefs are followed so they don't interfere with the comparison. All operators use the static equal_to() method.

Detailed Description

Struct/Union/Enum definition.

This class holds the tag and fields for struct/union/enum. Many different sueNodes may point to one suespecNode, but only the one that has is_elaborated equal to true actually "owns" the suespecNode. All suespecNode objects are stored in the unitNode. For a more detailed explanation see the related documentation.

The NodeType is sueSpec. However, there is a special field called _owner that will match that of the refering sueNode (either Struct, Union, or Enum).

Member Enumeration Documentation

enum typeNode::Type_qualifiers [inherited]
 

Type qualifiers.

This enum holds the possible type qualifiers. The special COMPATIBLE value indicates which type qualifiers are relevant when comparing two types for compatibility: const and volatile.

Enumeration values:
NONE  No type qualifier
CONST  Type is const
VOLATILE  Type is volatile
INLINE  Type is inline
COMPATIBLE  Mask the qualifiers that are relevant to type compatibility

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.

virtual typeNode* typeNode::base_type bool    TdefIndir const [inline, virtual, inherited]
 

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.

Node * suespecNode::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.

Parameters:
the_changer the specific Changer object to use.
redispatch pass true to revisit parts of the tree that have changed.

Implements Node.

virtual Node* suespecNode::clone   const [inline, virtual]
 

Clone the input node.

This is not a "deep" clone, so be careful. For a deep clone, use the ref_clone_changer class.

Returns:

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.

virtual void typeNode::dataflow FlowVal   v,
FlowProblem   fp
[inline, virtual, inherited]
 

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.

Parameters:
v the flow value to pass through the node.
fp the flow problem (specifying the transfer functions).

bool typeNode::equal_to typeNode   first,
typeNode   second,
bool    strict_toplevel,
bool    strict_recursive
[static, inherited]
 

Type comparison.

This static method compares two types, descending into the subtypes and following typedefs as necessary. The two boolean arguments control how strict the algorithm is with respect to type qualifiers. Passing true requires all type qualifiers to be the same. Passing false only requires those type qualifiers that affect compatibility to be the same. (Was TypeEqualQualified in type.c)

This routine relies on the qualified_equal_to() methods on each kind of typeNode to perform the appropriate comparison and dispatch to the sub-type when necessary.

See also:
qualified_equal_to()
Parameters:
first the first type
second the second type
strict_toplevel pass true to require strict comparison of top-level types
strict_recursive pass true to require strict comparson of sub-types
Returns:
true, if the types pass the equality test

pair< typeNode *, typeNode * > typeNode::usual_arithmetic_conversions typeNode   left,

Usual arithmetic conversions.

From ANSI 6.2.1.5: Many binary operators that expect operands of arithmetic type cause conversions and yield result types in a similar way. The purpose is to yield a common type, which is also the type of the result.

This method takes the types of the left and right operands and returns a pair of types indicating the conversions of the two operands, respectively. When necessary, these conversion include the integral promotions.

See also:

Returns:
