ucnid-2011-1.c: New test.
gcc/testsuite:
* c-c++-common/cpp/ucnid-2011-1.c: New test.
libcpp:
* ucnid.tab: Add C11 and C11NOSTART data.
* makeucnid.c (digit): Rename enum value to N99.
(C11, N11, all_languages): New enum values.
(NUM_CODE_POINTS, MAX_CODE_POINT): New macros.
(flags, decomp, combining_value): Use NUM_CODE_POINTS as array
size.
(decomp): Use unsigned int as element type.
(all_decomp): New array.
(read_ucnid): Handle C11 and C11NOSTART. Use MAX_CODE_POINT.
(read_table): Use MAX_CODE_POINT. Store all decompositions in
all_decomp.
(read_derived): Use MAX_CODE_POINT.
(write_table): Use NUM_CODE_POINTS. Print N99, C11 and N11
flags. Print whole array variable declaration rather than just
array contents.
(char_id_valid, write_context_switch): New functions.
(main): Call write_context_switch.
* ucnid.h: Regenerate.
* include/cpplib.h (struct cpp_options): Add c11_identifiers.
* init.c (struct lang_flags): Add c11_identifiers.
(cpp_set_lang): Set c11_identifiers option from selected language.
* internal.h (struct normalize_state): Document "previous" as
previous starter character.
(NORMALIZE_STATE_UPDATE_IDNUM): Take character as argument.
* charset.c (DIG): Rename enum value to N99.
(C11, N11): New enum values.
(struct ucnrange): Give name to struct. Use short for flags and
unsigned int for end of range. Include ucnid.h for whole variable
declaration.
(ucn_valid_in_identifier): Allow for characters up to 0x10FFFF.
Allow for C11 in determining valid characters and valid start
characters. Use check_nfc for non-Hangul context-dependent
checks. Only store starter characters in nst->previous.
(_cpp_valid_ucn): Pass new argument to
NORMALIZE_STATE_UPDATE_IDNUM.
* lex.c (lex_identifier): Pass new argument to
NORMALIZE_STATE_UPDATE_IDNUM. Call NORMALIZE_STATE_UPDATE_IDNUM
after initial non-UCN part of identifier.
(lex_number): Pass new argument to NORMALIZE_STATE_UPDATE_IDNUM.
