Didn't get any bites on this in cfe-dev, hopefully now that 3.1 has branched I can get a comment or two on this.
This is my first real deep dive into the clang guts, so I am submitting this patch to the dev list rather than commits so that it can get extra reviewing and critiquing. 2 Changes: 1) Cursors created from translation unit declarations will now be of kind CXCursor_TranslationUnit rather than the default CXCursor_UnexposedDecl 2) Cursor created by clang_getTranslationUnitCursor is now created with MakeCXCursor and includes the translation unit decl. This ensures that the cursor returned by clang_getTranslationUnitCursor and clang_getCursorLexicalParent in the case of a translation unit compare correctly via clang_equalCursors. The code to fetch the translation decl is based on code inside CursorVisitor::VisitChildren. I did not add any additional tests for this, but did re-run the current test suite. If someone could point me toward the best place to add said tests I would be happy to create some. Thanks -Evan
