* mdebugread.c (parse_symbol): Use new variable
nodebug_var_symbol_type as type of variables which don't have any ecoff debug info associated with them. (parse_symbol, parse_procedure): Use heuristics to determine if functions were compiled without debugging info and change their type to nodebug_function_symbol_type. (_initialize_mdebugread): Initialize nodebug_*_symbol_type. * source.c (line_info): Clear sal.pc for `info line' without arguments.
