[edit | edit source]

In addition to nodes and edges, ROSE AST may have attributes in addition to nodes and edges that are attached for preprocessing information like #include or #if .. #else. They are attached before, after, or within a nearby AST node (only the one with source location information.)

An example translator will traverse the input code's AST and dump information which may include preprocessing information.

For example 

exampleTranslators/defaultTranslator/preprocessingInfoDumper -c main.cxx
-----------------------------------------------
Found an IR node with preprocessing Info attached:
(memory address: 0x2b7e1852c7d0 Sage type: SgFunctionDeclaration) in file
/export/tmp.liao6/workspace/userSupport/main.cxx (line 3 column 1)
-------------PreprocessingInfo #0 ----------- :
classification = CpreprocessorIncludeDeclaration:
  String format = #include "all_headers.h"

relative position is = before

What is PreprocessingInfo

[edit | edit source]

It is a type of ROSE AST meta information to store source code comments.


They do not exist independently, but are attached to located sgnode.

  • before: before a code segment
  • after: after a code segment
  • inside: inside an empty scope

PreprocessingInfo::RelativePositionType position=PreprocessingInfo::before 

 enum RelativePositionType
	     {
	       defaultValue = 0, // let the zero value be an error value
	       undef        = 1, // Position of the directive is only going to be defined
	    // when the preprocessing object is copied into the AST,
	    // it remains undefined before that
	       before       = 2, // Directive goes before the correponding code segment
	       after        = 3, // Directive goes after the corresponding code segment
	       inside       = 4  // Directive goes inside the correponding code segment (as in between "{" and "}" of an empty basic block)
	     };


typedef Rose_STL_Container<PreprocessingInfo*> AttachedPreprocessingInfoType;

  • source comments: c style, c++ style
  • preprocessor info: include, define, ifdef, line declaration
  • and more

algorithm

[edit | edit source]

src/frontend/SageIII/attachPreprocessingInfoTraversal.C

The SgFile (always) constructor calls the function

  • void attachPreprocessingInfo(SgFile *sageFilePtr); which in turn calls
    • getPreprocessorDirectives (see above) and then

invokes a tree traversal in order to attach the preprocessor directives (i.e., the preprocessingInfo objects) to located nodes in the AST.

For this purpose, a data member attachedPreprocessingInfoType* attachedPreprocessingInfoPtr; is available to the SgLocatedNode class. This is done in ROSETTA/src/node.C.

Furthermore, There are corresponding access functions:

  • void addToAttachedPreprocessingInfo(preprocessingInfo *prepInfoPtr);
  • attachedPreprocessingInfoType* getAttachedPreprocessingInfo(void);

to the SgLocatedNode class. This is done in ROSETTA/Grammar/LocatedNode.code.

The tree traversal works as follows:

  • whenever it hits a located node
  • it checks if there is preprocessing info the line number of which is less or equal than the line number of the current located node (currently: of the current statement).
    • If this is the case, the corresponding preprocessing info is attached to the current located node (currently: before the current statement), unparse flag: "before". All this is done in the evaluateInheritedAttribute member function of the derived tree traversal class.
  • The evaluateSynthesizedAttribute member function deletes the list of preprocessingInfo objects as soon as the traversal returns to a SgFile object and attaches trailing preprocessing information to the last located node (currently to the last statement) that has been visited in the file (unparse flag: "after").

Node that the preprocessingInfo objects are always attached to AST nodes. By switching the USE_OLD_MECHANISM_OF_HANDLING_PREPROCESSING_INFO flag, you only change the mechanism which the unparser is based on! If USE_OLD_MECHANISM_OF_HANDLING_PREPROCESSING_INFO is set to 1, then the unparser simply ignores the preprocessingInfo objects that have been attached to the AST nodes.

Problems with the handling of preprocessing information can be found in the directory ROSE/TESTS/KnownBugs/AttachPreprocessingInfo.

attaching function

[edit | edit source]

// frontend/SageIII/attachPreprocessingInfoTraversal.C

void AttachPreprocessingInfoTreeTrav::iterateOverListAndInsertPreviouslyUninsertedElementsAppearingBeforeLineNumber ( SgLocatedNode* locatedNode, int lineNumber, PreprocessingInfo::RelativePositionType location, bool reset_start_index, ROSEAttributesList *currentListOfAttributes)


different call sites of iterateOverListAndInsertPreviouslyUninsertedElementsAppearingBeforeLineNumber()

how to decide on different locations

  • before: AttachPreprocessingInfoTreeTrav::evaluateInheritedAttribute ( SgNode *n,AttachPreprocessingInfoTreeTraversalInheritedAttrribute inheritedAttribute)
    • attach to the current statement's before position if traversal is in evaluateInheritedAttribute()
      • calling iterateOverListAndInsertPreviouslyUninsertedElementsAppearingBeforeLineNumber(currentLocNodePtr,line,PreprocessingInfo::before, reset_start_index, currentListOfAttributes );
  • inside: AttachPreprocessingInfoTreeTrav::evaluateSynthesizedAttribute( SgNode *n, AttachPreprocessingInfoTreeTraversalInheritedAttrribute inheritedAttribute, SubTreeSynthesizedAttributes synthiziedAttributeList)
    • attach to the inside position of a multiline located node when leaving the node during evaluateSynthesizedAttribute()
  • after: AttachPreprocessingInfoTreeTrav::evaluateSynthesizedAttribute( SgNode *n, AttachPreprocessingInfoTreeTraversalInheritedAttrribute inheritedAttribute, SubTreeSynthesizedAttributes synthiziedAttributeList)
    • e.g. attach to the previous located node 's after position if the traversal is leaving V_SgSourceFile during evaluateSynthesizedAttribute()

comments

[edit | edit source]

Not all Located nodes can have comments!! 

     SgFunctionDeclaration* functionDeclaration = isSgFunctionDeclaration(n);
     if (functionDeclaration != NULL)
        {
          string comment = string("// Auto-comment function name: ") +
                           functionDeclaration->get_name().str() +
                           " is now a commented function";
          PreprocessingInfo* commentInfo =
               new PreprocessingInfo(PreprocessingInfo::CplusplusStyleComment,
               comment,"user-generated",0, 0, 0, PreprocessingInfo::before);
          functionDeclaration->addToAttachedPreprocessingInfo(commentInfo);
        }

arbitrary text

[edit | edit source]

More versatile than comments: 

    SgLocatedNode* node = *iter2;
      std::ostringstream o;
      o<<node;
      std::string text = "\n/* HPCToolKit raw data: " +profileNode->toString();
      text += " -> "+ string(node->sage_class_name()) + " " + o.str() + "*/\n"; 
      // attach the text before the node (node is e_after the text)
      SageInterface::addTextForUnparser(node,text,AstUnparseAttribute::e_after);

deletion

[edit | edit source]

Cannot remove elements while iterating the container. Save a subset of elements into another container and remove them later on 

 
  AttachedPreprocessingInfoType *comments =
    node->getAttachedPreprocessingInfo ();
  if (comments==NULL)
    return 0;
  AttachedPreprocessingInfoType::iterator i;
  std::vector< PreprocessingInfo* > removeList;
  for (i = comments->begin (); i != comments->end (); i++)
  { 
       // if...
      removeList.push_back(*i);"
   }

   // remove those comments
  for (std::vector<PreprocessingInfo* >::iterator j = removeList.begin();
       j!=removeList.end();j++)
  {
    comments->erase(find(comments->begin(), comments->end(),*j));
    // free memory also?
    free(*j);

  }

Move comments to new statements

[edit | edit source]

Source comments and #if directives should be preserved when we remove or replace statements in the AST

A possible call stack is

  • SageInterface::removeStatement () from src/frontend/SageIII/sageInterface/sageInterface.C:10086
    • SageInterface::moveCommentsToNewStatement from src/frontend/SageIII/sageInterface/sageInterface.C:10193
