* cpphash.c (CPP_IS_MACRO_BUFFER, FORWARD, PEEKC): Delete. (macro_cleanup): No need to cast pbuf->macro. (collect_expansion): Use _cpp_get_define_token. Goto done if it returns VSPACE. Remove check for trailing space after CPP_COMMENT. (_cpp_create_definition): Don't diddle flags here. Return directly on error. (unsafe_chars): Handle c1 being EOF. (push_macro_expansion): Use unsafe_chars for both accidental-paste checks. Don't push the buffer till after we're done with them. * cpplex.c (PEEKBUF, GETBUF, FORWARDBUF): New. (PEEKN, FORWARD, GETC, PEEKC): Use them. (cpp_push_buffer): Don't set new->alimit. Set new->mark appropriately. (_cpp_parse_assertion): Don't NUL terminate. (_cpp_lex_token): Fix -traditional macro handling. Don't skip hspace before calling _cpp_parse_assertion. Remove all sets of only_seen_white. Treat '\f' as hspace. Don't do anything special with '\n' here. (maybe_macroexpand): Handle T_EMPTY hash entries without pushing a buffer at all. (cpp_get_token): Handle clearing only_seen_white here. Handle incrementing the line number here. Clear potential_control_macro as well as only_seen_white, if appropriate. (cpp_get_non_space_token): Don't eat CPP_POP tokens. (_cpp_get_define_token): New function, basically like _cpp_get_directive_token was but doesn't eat horizontal space. Don't do anything with only_seen_white here. (_cpp_get_directive_token): Just call _cpp_get_define_token repeatedly till it returns non-hspace. * cpplib.c (PEEKN, FORWARD, GETC, PEEKC): Delete. (conditional_skip, skip_if_group): Return int. (DIRECTIVE_TABLE): Change origin of all conditional directives to "COND". (TRAD_DIRECT_P): New macro. (_cpp_handle_directive): Use _cpp_get_directive_token. Issue an error for a bogus directive, unless -lang-asm. Use TRAD_DIRECT_P. Loop calling handler functions till one returns zero. (get_macro_name): Don't diddle flags here. (do_define): Diddle flags here. Use _cpp_get_directive_token. Create T_EMPTY nodes for #define macro /* nothing */. (do_undef): Don't copy the name. Use _cpp_get_directive_token. Use hp->name when calling pass_thru_directive. (do_if, do_else, do_elif, do_ifdef, do_ifndef, conditional_skip): Return the result of conditional_skip and/or skip_if_group. Don't call _cpp_output_line_command. (consider_directive_while_skipping): Use _cpp_get_directive_token. Issue -Wtraditional warnings as appropriate. Don't complain about unrecognized directives. If we are to stop skipping, return the number of the directive that ended the skip. (skip_if_group): Use _cpp_get_directive_token. Turn off macro expansion and line commands while skipping. Return the result of consider_directive_while_skipping, if nonzero. (do_endif): Just set potential_control_macro here. (validate_else): Use _cpp_get_directive_token. (do_assert, do_unassert): Don't save pointers into the token_buffer across calls to the lexer. Use _cpp_get_directive_token. * cpplib.h (cpp_buffer): Remove alimit and colno. Make mark a pointer, not an offset. Replace 'data', which was a generic pointer, with 'macro', which points to a struct hashnode. (cpp_reader): Add 'potential_control_macro' pointer. * cpphash.h (T_UNUSED): Replace with T_EMPTY. (CPP_BUF_GET, CPP_FORWARD): Delete. (CPP_IN_COLUMN_1, ADJACENT_TO_MARK): New macros. (CPP_IS_MACRO_BUFFER, CPP_SET_BUF_MARK, CPP_GOTO_BUF_MARK, ACTIVE_MARK_P): Update. (_cpp_get_define_token): New internal function. * cppfiles.c (read_include_file): Don't set fp->alimit or fp->colno.
