It also has a little more impact - it adds a word of memory per argument per method per class. I don't think the storage is an issue right now, and some day I intend to go through and clean up our memory usage a little bit in places much more severe than this. Other than that it's pretty straightforward. OK to commit? -- Daniel Jacobowitz Carnegie Mellon University MontaVista Software Debian GNU/Linux Developer 2002-01-15 Daniel Jacobowitz * gdbtypes.h (struct method_args): New. (struct type): Change arg_types to method_args. Change TYPE_ARG_TYPES to TYPE_METHOD_ARGS. Add TYPE_ARG_TYPE, TYPE_FN_FIELD_ARG. (smash_to_method_type): Update prototype to accept struct method_args. * gdbtypes.c (smash_to_method_type): Update to use TYPE_METHOD_ARGS. (check_stub_method): Likewise. Initialize method arguments to non-artificial. (print_arg_types): Update to accept struct method_args. Print out new field ``artificial'' for each argument. (dump_fn_fieldlists): Fix indentation of type dumps. (recursive_dump_type): Update to use TYPE_METHOD_ARGS. * dwarf2read.c (dwarf2_add_member_fn): Update to use struct method_args. Preserve TYPE_FIELD_ARTIFICIAL. * stabsread.c (read_type): Update to use struct method_args. (read_args): Likewise. Initialize artificial to 0. * valops.c (hand_function_call): Update to use struct method_args. (typecmp): Likewise. (find_overload_match): Update to use TYPE_FN_FIELD_ARG. * c-typeprint.c (cp_type_print_method_args): Update to accept struct method_args. Skip leading artificial arguments. (c_type_print_args): Likewise. diff -urp src-p3/gdb/c-typeprint.c src-final/gdb/c-typeprint.c --- src-p3/gdb/c-typeprint.c Tue Jan 15 14:38:27 2002 +++ src-final/gdb/c-typeprint.c Tue Jan 15 14:30:21 2002 @@ -41,7 +41,7 @@ /* Flag indicating target was compiled by HP compiler */ extern int hp_som_som_object_present;
