* c-parse.in (_yylex): Use _cpp_backup_tokens. * cpphash.h (struct tokenrun): Add prev. (struct lexer_state): Remove bol. (struct cpp_reader): Remove old lookahead stuff, add lookaheads. (_cpp_free_lookaheads, _cpp_release_lookahead, _cpp_push_token) : Remove. * cppinit.c (cpp_create_reader): Don't set bol. (cpp_destroy): Don't free lookaheads. * cpplex.c (lex_directive): Remove. (next_tokenrun): Update. (_cpp_lex_token): Clean up logic. (lex_token): Update to return a pointer to lexed token, since it can move to the start of the buffer. Simpify newline handling. * cpplib.c (SEEN_EOL): Update. (skip_rest_of_line): Remove lookahead stuff. (end_directive): Line numbers are already incremented. Revert to start of lexed token buffer if we can. (_cpp_handle_directive, do_pragma, do_pragma_dependency, parse_answer): Use _cpp_backup_tokens. (run_directive, cpp_pop_buffer): Don't set bol, set saved_flags instead. Don't check for EOL. (do_include_common, do_line, do_pragma_system_header): Use skip_rest_of_line. * cpplib.h (BOL, _cpp_backup_tokens): New. * cppmacro.c (save_lookahead_token, take_lookahead_token, alloc_lookahead, free_lookahead, _cpp_free_lookaheads, cpp_start_lookahead, cpp_stop_lookahead, _cpp_push_token): Remove. (builtin_macro): Don't use cpp_get_line. (cpp_get_line): Short term kludge. (parse_arg): Handle directives in arguments here. Back up when appropriate. Store EOF at end of argument list. (funlike_invocation_p): Use _cpp_backup_tokens. (push_arg_context): Account for EOF at end of list. (cpp_get_token): Remove lookahead stuff. Update. * gcc.dg/cpp/directiv.c: Update. * gcc.dg/cpp/undef1.c: Update. From-SVN: r45582
