2000-03-01cpplib.h (CPP_ASSERTION, [...]): New token types.Zack Weinberg1-47/+59
* cpplib.h (CPP_ASSERTION, CPP_STRINGIZE, CPP_TOKPASTE): New token types. (struct cpp_reader): Add parsing_if_directive and parsing_define_directive flags. (struct cpp_options): Remove output_conditionals flag. (check_macro_name): Delete prototype. * cpphash.h (struct macrodef): Delete. (struct reflist): Separate from struct definition. (struct definition): Remove unused fields. Add column number. (create_definition): Returns a DEFINITION *. Takes a cpp_reader * and an int. * cpphash.c (SKIP_WHITE_SPACE): Delete. (PEEKC): Copy defn from cpplib.c. (rest_extension, REST_EXTENSION_LENGTH): Delete. (struct arg): New. (struct arglist): Simplify. (collect_expansion): Rewrite. Get tokens by calling cpp_get_token. Add more error checking. (collect_formal_parameters): New function, broken out of create_definition and reworked to use get_directive_token. (create_definition): All real work is now in collect_expansion and collect_formal_parameters. do_define handles finding the macro name. Return a DEFINITION, not a MACRODEF. (macroexpand): Replace bcopy with memcpy throughout. Replace character-at-a-time copy loop with memcpy and pointer increments. (compare-defs): d1->argnames / d2->argnames might be null. * cpplib.c (copy_rest_of_line): Delete function. (skip_rest_of_line): Do all the work ourselves. (skip_string): New function. (parse_string): Use skip_string. (get_macro_name): New function. (check_macro_name): Delete. (copy_comment): Use CPP_RESERVE and CPP_PUTC_Q. (cpp_skip_hspace): Use CPP_BUMP_LINE. (handle_directive): ICE if we're called on a macro buffer. (do_define): Determine macro name and type (funlike/objlike) here. Expunge all uses of MACRODEF. (cpp_push_buffer): Set line_base to NULL. (do_undef, read_line_number): Don't worry about getting a POP token. (eval_if_expression): Set/reset parsing_if_directive around cpp_parse_expr. Don't clear only_seen_white. (skip_if_group): Remove output_conditionals logic. Use skip_rest_of_line. (cpp_get_token): Return ASSERTION, STRINGIZE, and TOKPASTE tokens under appropriate conditions. (cpp_unassert): Call do_unassert not do_assert. Oops. * cppexp.c (parse_defined): New function, break out of cpp_lex. (cpp_lex): We now get CPP_ASSERTION tokens and can check them ourselves, with cpp_defined. * cppinit.c (cpp_handle_option, print_help): Delete -ifoutput. * gcc.dg/20000209-2.c: Turn off -pedantic-errors. * gcc.dg/strpaste-2.c: New.
