A plugin can call any non-static function in GCC, with the conditions for its inputs and when it can be called being the same as for a direct call from GCC; this is a consequence of the design to use -rdynamic. These may variously be documented in comments, the internals manual, list archives and collective wisdom. If you want better documentation for a particular function, find where the existing documentation is (comments or internals manual) and propose a patch. If you think a static function should be made non-static so plugins can call it, propose a patch with appropriate rationale. -- Joseph S. Myers jos...@codesourcery.com
