2004-09-20 Matt Austern <austern@apple.com> Zack Weinberg <zack@codesourcery.com> * c-common.c (fix_string_type): Build the unqualified array type unconditionally, then use c_build_qualified_type to get the proper const-qualified variant, and set its TYPE_MAIN_VARIANT to refer to the unqualified type. * c-lex.c (c_lex_return_raw_string): New global. (c_lex_with_flags): Honor it. * c-pragma.h: Declare it. cp: * decl.c (make_rtl_for_nonlocal_decl, start_preparsed_function): Apply lbasename to input_filename before passing to get_fileinfo. * semantics.c (begin_class_definition): Likewise. * lex.c (handle_pragma_interface): Apply get_fileinfo to the correct filename. Rename variables to be less confusing. (handle_pragma_implementation): Likewise. Disable "appears after file is included" diagnostic. * parser.c (struct cp_token): Add in_system_header fiag. (CP_TOKEN_BLOCK_NUM_TOKENS, struct cp_token_block) (CP_TOKEN_BUFFER_SIZE, cp_token_cache_push_token) (CPP_NONE, cp_lexer_read_token): Delete. (struct cp_lexer): Remove first_token, string_tokens, main_lexer_p fields. Clarify comments. (struct cp_token_cache): Now just a pair of pointers. (CP_LEXER_BUFFER_SIZE): New #define. (CPP_PURGED): New fake token type. (cp_lexer_new_from_token_array, cp_lexer_destroy) (cp_lexer_peek_token_emit_debug_info, cp_lexer_skip_purged_tokens) (cp_lexer_handle_pragma, cp_token_cache_new, cp_parser_string_literal): New functions. (cp_lexer_new_from_tokens): Now a simple wrapper around cp_lexer_new_from_token_array. (cp_lexer_set_source_position_from_token): Also update in_system_header. (cp_lexer_next_token, cp_lexer_prev_token, cp_lexer_advance_token): Don't wrap round. (cp_lexer_token_difference): Dont handle wrapping round. (cp_lexer_new_main): Enable pragma deferral and raw strings, read the entire translation unit through c_lex_with_flags into this lexer's buffer, then turn raw strings back off again. (cp_lexer_grow_buffer): Adjust for buffer no longer being circular. (cp_lexer_get_preprocessor_token): No need to handle not being the main lexer. Set token->in_system_header too. (cp_lexer_peek_token): Skip purged tokens. Feed pragma tokens to cp_lexer_handle_pragma. No need to call cp_lexer_read_token. (cp_lexer_peek_nth_token): Likewise. (cp_lexer_purge_token): Mark the token PURGED, don't shift all the other tokens down. (cp_lexer_purge_tokens_after): Likewise. (cp_lexer_save_tokens, cp_lexer_rollback_tokens): Don't worry about there being no tokens. (cp_lexer_print_token): Revise to give useful information on all tokens. (struct cp_parser): Add field translate_strings_p. (cp_parser_new): Initialize it. (cp_parser_translation_unit): Destroy the lexer when done. (cp_parser_parameter_declaration): Restructure saving of default arguments. (cp_parser_save_member_function_body): Likewise. (cp_parser_check_for_invalid_template_id) (cp_parser_nested_name_specifier_opt, cp_parser_template_id): Adjust calls to cp_lexer_advance_token. (cp_parser_skip_to_closing_parenthesis, cp_parser_declaration): No need to fiddle c_lex_string_translate. (cp_parser_primary_expression, cp_parser_linkage_specification) (cp_parser_asm_definition, cp_parser_asm_specification_opt) (cp_parser_asm_operand_list, cp_parser_asm_clobber_list) Use cp_parser_string_literal. (cp_parser_attribute_list): Save and restore parser->translate_strings_p, not c_lex_string_translate. (cp_parser_cache_group): Delete. (cp_parser_cache_group_1): Rename cp_parser_cache_group. Do not take a cache argument. From-SVN: r87786
