| Re: [ptp-dev] Detecting pragma into CDT files |
Yes the OpenMP code for detecting #pragmas (and the rest of the OpenMP analysis) was written several years ago, before the CDT AST had #pragma nodes in it.
So I think what we do now is wrapper the CDT #pragma nodes with our original classes, so that may confuse things a bit. It would be simpler if we were to rewrite it today.
You could ask on the cdt-dev list and probably find a more direct route for finding #pragmas than what we've done here in PLDT.
Have you tried using the CDT's DOM AST view? It's helpful for learning about the CDT's AST nodes.
Install the "CDT Testing Feature" and then open the CDT's "DOM AST View" to see an AST tree view of whatever the editor is open on.
I haven't looked at that view in a while, and the #pragma of a small sample program didn't seem to show up there. Hmmmm.
Also, if you look at a talk from EclipseCon last year: http://www.eclipsecon.org/2008/?page=sub/&id=373
It has some hints about configuring the ASTs that are built - e.g. you have to give an extra argument to get the comments.
Now I wonder if there's an extra argument to get the preprocessor statements too. (ASTVisitor.shouldVisitXXXXX etc)
Ah yes, slide 6 reminds me that there is an IASTPreprocessorPragmaStatement node (which didn't exist when we first wrote our OpenMP analysis code in PLDT)
Slide 8 shows you the DOM AST view; Slide 11 shows how to use ast.getAllPreprocessorStatements();
Hopefully that helps you get started.
