Ping.
I apologize for the poorly named subject of this submission, but rather
than resubmit, I figured it would be better to continue the thread.
This patch fixes clang_getCursorExtent() when called with a CXCursor of
kind CXCursor_TranslationUnit.
Currently, the following snippet (using libclang) will return an empty
range:
CXCursor Cursor = clang_getTranslationUnitCursor(TranslationUnit);
CXSourceRange Range = clang_getCursorExtent(Cursor);
This patch will cause the range to include the entire file from which the
translation unit was created. I have a attached the fresh patch.
Thanks,
Clint
