Subject: Make the Transformer respect 'skip' annotations
X-Git-Tag: GOBJECT_INTROSPECTION_1_29_17~83
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=d19fcd098ed69d9216efbf68fc8ae4ba57d09638;p=platform%2Fupstream%2Fgobject-introspection.git

Make the Transformer respect 'skip' annotations

 * In order to suppress unnecessary warnings on macros which are skipped
   at later passes of the scanning, we use the annotations to skip
   AST stuff being created for symbols that are skipped.
