Subject:         * tree.c (decl_function_context): Handle virtual functions.
X-Git-Tag: upstream/4.9.2~104156
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=53bdb86c380f3f819d819ee928f00eb6bfad5d05;p=platform%2Fupstream%2Flinaro-gcc.git

    * tree.c (decl_function_context): Handle virtual functions.

        * tlink.c (scan_linker_output): Don't look in demangled name when
        looking for linker output keywords.

        * dwarfout.c (output_type): We can defer namespace-scope classes.
