"--file-ordering" options. (usage): Add new options to usage message. (main): Handle new options. * gprof.h (STYLE_FUNCTION_ORDER): Define. (STYLE_FILE_ORDER): Define. (function_mapping_file): Declare. * cg_arcs.c (arcs, numarcs): New globals. (arc_add): Put new arcs into the arc array so the function/file ordering code can examine them. * cg_arcs.h (struct arc): New field "has_been_placed". (arcs, numarcs): Declare new globals. * core.c (symbol_map, symbol_map_count): New globals. (read_function_mappings): New function to read in a function to object map file. (core_init): Call read_function_mappings if a function mapping file exists. (core_create_function_syms): Handle function to object file mappings. * symtab.h (struct sym): New fields "mapped", "has_been_placed", "nuses", "prev". * cg_print.c (cmp_arc_count): New function for sorting arcs. (cmp_fun_nuses): Likewise for functions. (cg_print_function_ordering): New function to print a suggested function ordering. (cg_print_file_ordering): Likewise for ordering .o files. (order_and_dump_functions_by_arcs): Helper function for function and object file ordering code. Gprof changes for mentor vm work.
