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. libstdc++-v3: * testsuite/22_locale/collate/compare/wchar_t/2.cc * testsuite/22_locale/collate/compare/wchar_t/wrapped_env.cc * testsuite/22_locale/collate/compare/wchar_t/wrapped_locale.cc * testsuite/22_locale/collate/hash/wchar_t/2.cc * testsuite/22_locale/collate/hash/wchar_t/wrapped_env.cc * testsuite/22_locale/collate/hash/wchar_t/wrapped_locale.cc * testsuite/22_locale/collate/transform/wchar_t/2.cc * testsuite/22_locale/collate/transform/wchar_t/wrapped_env.cc * testsuite/22_locale/collate/transform/wchar_t/wrapped_locale.cc: XFAIL on all targets.
