Sg_File_Info Class Reference

Description

This class represents the location of the code associated with the IR node in the original source code.

This object is used to represent the starting and the ending position of the source code associated with some IR nodes (in other cases the endOfConstruct returnes the same data as the startOfConstruct).

Classification of the IR nodes is included in this object and applies to:
- SgStatements
- SgExpression
- SgInitializedName
- SgFile (and maybe SgDirectory)
- Perhaps also SgTemplateArguments, SgTemplateParameters, SgBaseClass

classifications are:

Note that p_filename is correctly initialized in the Sg_File_Info object for a SgGlobal, but the p_line and p_col are set to 0 (zero). All other IR nodes have valid Sg_File_Info objects with correct p_filename and p_line and p_col set to nonzero values. A few IR nodes in the AST will have a default value of their Sg_File_Info nodes with p_filename set to "NULL_FILE" and p_line and p_col set to 0 (zero). These are increasingly rare to find in the AST, but since some IR nodes can't be associated with their source position in the AST they persist.

Member Enumeration Documentation

Enum type containing classifications if IR nodes.

This is part of the classification mechanism for IR nodes within ROSE. Compiler generated code is not output in the code generation phase, but some compiler generated IR nodes must be output so such nodes are explicitly marked within the classification process (implemented in ASTFixes.C).

  • Examples of transformation IR nodes include:
    1. Any relocated AST subtrees
    2. Any new IR nodes
  • Examples of compiler-generated IR nodes include:
    1. Any implicit or unnecessary casts not explicitly represented in the source code
    2. Instantiated templates
  • Examples of compiler-generated code marked for output (in code generation phase) include:
    1. Any transformed template instantiations
    2. required templates assigned to specific files (see ROSE prelinking details)
  • Examples of shared IR nodes include:
    1. All types (not implemented yet)
    2. All IR nodes shared across originally separate ASTs (see AST Merge Mechanism)
  • Examples of frontend specific IR nodes include:
    1. float __builtin_acosf (float __builtin__x);
    2. #define __builtin_va_start va_start
    3. All functions and variables defined in "rose_edg_required_macros_and_functions.h"

Member Function Documentation

virtual SgNode* Sg_File_Info::copy ( SgCopyHelp help) const
virtual

This function clones the current IR node object recursively or not, depending on the argument.

This function performs a copy based on the specification of the input parameter. The input parameter is used to determin which data members are copied by reference and which are copied by value.

Parameters

Reimplemented from SgSupport.

virtual bool Sg_File_Info::isInMemoryPool ( )
virtual

FOR INTERNAL USE This is used in internal tests to verify that all IR nodes are allocated from the heap.

The AST File I/O depends upon the allocation of IR nodes being from the heap, stack based or global IR nodes should not appear in the AST if it will be written out to a file and read back in. To enforce this concept, this function implements a test to verify that the IR node can be found on the heap and is part of a larger test of the whole AST. This test must pass before the AST can be written out to a file. This is part of a compromise in the design of the AST File I/O to support binary streaming of data to files; for performance. It is also rather difficult, but possible, to build a useful AST with IR nodes allocated on the stack or frm global scope, this test filters out such cased from being used with the AST File I/O mechanism.

virtual std::vector<std::pair<SgNode*,std::string> > Sg_File_Info::returnDataMemberPointers ( ) const
virtual

FOR INTERNAL USE Returns STL vector of pairs of SgNode* and strings for use in AST tools

This functions is part of general support for many possible tools to operate on the AST. The forms a list of ALL IR node pointers used by each IR node, and is a supperset of the get_traversalSuccessorContainer(). It is (I think) less than the set of pointers used by the AST file I/O. This is part of work implemented by Andreas, and support tools such as the AST graph generation.

Warning
This function can return unexpected data members and thus the order and the number of elements is unpredicable and subject to change.
Returns
STL vector of pairs of SgNode* and strings

Reimplemented from SgSupport.

virtual void Sg_File_Info::processDataMemberReferenceToPointers ( ReferenceToPointerHandler *  )
virtual

FOR INTERNAL USE Processes pairs of references to SgNode* and strings for use in AST tools

This functions similar to returnDataMemberPointers() except that it passes references to a handler object. As a result there is FAR more damage that can be done by using this function, but it is type-safe. This is provided for support of internal tools that operate on the AST, e.g the AST Merge mechanism.

Warning
This function can return unexpected data members and thus the order and the number of elements is unpredicable and subject to change.

Reimplemented from SgSupport.

virtual long Sg_File_Info::getChildIndex ( SgNode childNode) const
virtual

FOR INTERNAL USE Returns a unique index value for the childNode in the list of children at this IR node.

This function returns a unique value for the input childNode in set of children at this IR node. Note that a negative value indicates that the input node is not a child. This is the basis for the implementation of the isChild(SgNode*) member function. Data members that are NULL in the IR node are counted internally (so that this function returns value that could be statically defined, and so are not dynamically determined).

Warning
The mapping on children to integer values could change from release to release of ROSE.
Returns
long

Reimplemented from SgSupport.

Sg_File_Info* Sg_File_Info::addRegExpAttribute ( std::string  s,
AstRegExAttribute *  a 
)

Support for AST matching using regular expression.

This support is incomplete and the subject of current research to define RegEx trees to support inexact matching.

Member Data Documentation

Sg_File_Info::p_file_id
protected

This is a key that maps integers to file names, it prevents redundent storage of filename strings.

This is part of a mechanism to reduce the memory requirements of the IR (to support whole program analysis in ROSE). The values are keys to an STL map which relates file ids to file name strings, allowing a more compressed representation of the filename data in the Sg_File_Info object. There are two maps, one for finding the filename string from a file id integer (p_fileidtoname_map), and another for the reverse map (p_nametofileid_map).

Definition at line 23062 of file Cxx_Grammar.h.

Sg_File_Info::p_line
protected

This is the line number of the location of the source code for this IR node.

This information is useful in the heuristics of attaching comments to IR nodes (SgStatement and SgExpression IR nodes).

The value of this variable is always greater than or equal to zero. In the case of isCompilerGenerated() == true or isTransformation() == true then value is INT_MAX-1. This value if define for this case so that all comments will be attached before the associated statement.

Definition at line 23066 of file Cxx_Grammar.h.

Sg_File_Info::p_col
protected

This is the column number of the location of the source code for this IR node.

This information is useful in the heuristics of attaching comments to IR nodes (SgStatement and SgExpression IR nodes).

The value of this variable is always greater than or equal to zero. If IR node is compiler generated for a transformation then value is set to INT_MAX-1.

Definition at line 23070 of file Cxx_Grammar.h.

Sg_File_Info::p_classificationBitField
protected

This is mechanism for classification of the IR node.

IR nodes use this mechanism to classify themselves as either part of a transformation or compiler generated (other enum values of Sg_File_Info::classifier are not used).

Definition at line 23074 of file Cxx_Grammar.h.

Sg_File_Info::p_fileIDsToUnparse
protected

This set contains a list of all file ids for which the accompanying IR node should be unparsed.

This is part of the AST Merge mechanism. This set contains a list of file ids. During unparsing, if we encounter a node with this Sg_File_Info object, we only want to unparse this file if the file we are currently unparsing is in this list.
