Ulrich Drepper  <drepper@cygnus.com>
        * Makefile.in (OBJS): Add graph.o
        (graph.o): New dependency list.
        * flags.h: Declare dump_for_graph and define graph_dump_types type.
        * print-rtl.c (dump_for_graph): Define new variable.
        (print_rtx): Rewrite to allow use in graph dumping functions.
        * toplev.c: Declare print_rtl_graph_with_bb, clean_graph_dump_file,
        finish_graph_dump_file.
        Define graph_dump_format.
        (compile_file): If graph dumping is enabled also clear these files.
        Finish graph dump files.
        (rest_of_compilation): Also dump graph information if enabled.
        (main): Recognize -dv to enabled VCG based graph dumping.
        * graph.c: New file.  Graph dumping functions.
