* cpplib.h (CPP_AT_NAME, CPP_OBJC_STRING): New token types.
(struct cpp_options): Add narrow_charset, wide_charset,
bytes_big_endian fields. Remove EBCDIC field.
(cpp_init_iconv, cpp_interpret_string): New external interfaces.
* cpphash.h: Include <iconv.h> if we have it, otherwise
provide a dummy definition of iconv_t.
(struct cpp_reader): Add narrow_cset_desc and wide_cset_desc fields.
(_cpp_valid_ucn): Update prototype.
(_cpp_destroy_iconv): New prototype.
* doc/cpp.texi: Document character set handling.
* doc/cppopts.texi: Document -fexec-charset= and -fexec-wide-charset=.
* doc/extend.texi: Delete entire section on multiline strings.
Rewrite section on __FUNCTION__ etc now that these are
variables in C.
* cppucnid.tab, cppucnid.pl: New files.
* cppucnid.h: New generated file.
* cppcharset.c: Include cppucnid.h. Lots of commentary added.
(iconv_open, iconv, iconv_close): Provide dummy definitions
if !HAVE_ICONV.
(SOURCE_CHARSET, struct strbuf, init_iconv_desc, cpp_init_iconv,
_cpp_destroy_iconv, convert_cset, width_to_mask, convert_ucn,
emit_numeric_escape, convert_hex, convert_oct, convert_escape,
cpp_interpret_string, narrow_str_to_charconst,
wide_str_to_charconst): New.
(ucn_valid_in_identifier): Use a binary search through the
ucnranges table defined in cppucnid.h, not a long chain of if
statements.
(_cpp_valid_ucn): Add a limit pointer. Downgrade "universal
character names are only valid in C++ and C99" to a warning.
Issue the "meaning of \[uU] is different in traditional C"
warning here. Take care not to let iconv see an invalid UCS
value if we get a malformed UCN. Issue an error if we don't
have iconv.
(cpp_interpret_charconst): Moved here from cpplex.c. Use
cpp_interpret_string to do the heavy lifting.
* cppinit.c (cpp_create_reader): Initialize bytes_big_endian,
narrow_charset, wide_charset fields of options structure.
(cpp_destroy): Call _cpp_destroy_iconv.
* cpplex.c (forms_identifier_p): Adjust call to _cpp_valid_ucn.
(maybe_read_ucn, hex_digit_value, cpp_parse_escape): Delete.
(cpp_interpret_charconst): Moved to cppcharset.c.
* cpplib.c (dequote_string): Delete.
(interpret_string_notranslate): New.
(do_line, do_linemarker): Use interpret_string_notranslate.
* Makefile.in (cppcharset.o): Depend on cppucnid.h.
* c-common.c (fname_string, combine_strings): Delete.
* c-common.h (fname_string, combine_strings): Delete prototypes.
* c-lex.c (ignore_escape_flag): Delete.
(cb_ident): Use cpp_interpret_string, not lex_string.
(get_nonpadding_token): New function.
(c_lex): Handle Objective-C @-prefixed identifiers and strings here.
Adjust calls to lex_string. Don't write *value twice.
(lex_string): Now handles string constant concatenation.
Most of the work handed off to cpp_interpret_string.
Call fix_string_type here.
* c-parse.in (STRING_FUNC_NAME, VAR_FUNC_NAME): Replace with
FUNC_NAME, throughout.
(OBJC_STRING): New token type.
(primary:STRING): No need to call fix_string_type here.
(primary:objc_string): Make that OBJC_STRING.
(objc_string nonterminal): Delete.
(yylexname): Delete code to handle fake string constants.
(yylexstring): Delete entirely.
(_yylex): Handle CPP_AT_NAME and CPP_OBJC_STRING. No need
to handle CPP_ATSIGN.
* c.opt (-fexec-charset=, -fwide-exec-charset=): New options.
* c-opts.c (missing_arg, c_common_handle_option): Handle
OPT_fexec_charset_ and OPT_fwide_exec_charset_.
(c_common_init): Set cpp_opts->bytes_big_endian, not
cpp_opts->EBCDIC. Call cpp_init_iconv.
(print_help): Document -fexec-charset= and -fexec-wide-charset=.
(TARGET_EBCDIC): Delete default definition.
* objc/objc-act.c (build_objc_string_object): No need to
handle string constant concatenation.
cp:
* parser.c (cp_lexer_read_token): No need to handle string
constant concatenation.
testsuite:
* gcc.c-torture/execute/wchar_t-1.x: New file; XFAIL wchar_t-1.c
everywhere.
* gcc.dg/concat.c: Concatenation of string constants with
__FUNCTION__ / __PRETTY_FUNCTION__ is now a hard error.
* gcc.dg/wtr-strcat-1.c: Loosen dg-warning regexp.
* gcc.dg/cpp/escape-2.c: Use wide character constants where
necessary to avoid multi-character character constant warning.
* gcc.dg/cpp/escape.c: Likewise.
* gcc.dg/cpp/ucs.c: Likewise.
Remove backslashes from dg-bogus comments, as they confuse Tcl.
Fix a typo.
