            Bug ID: 60954
           Summary: gcc-plugin.h should set default visibility
           Product: gcc
           Version: unknown
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: plugins
          Assignee: unassigned at gcc dot gnu.org
          Reporter: tromey at gcc dot gnu.org

gcc-plugin.h declares two symbols that must be
exported by the plugin: plugin_is_GPL_compatible and plugin_init.

I think it would be nice for plugin authors if these two
declarations had __attribute__((__visibility__("default"))).
That way they would get the correct visibility automatically,
regardless of how the plugin was built.
