Update.
2003-12-23 Paolo Bonzini <bonzini@gnu.org>
* posix/regex_internal.c (re_dfa_add_node): Initialize opt_subexp.
* posix/regex_internal.h (re_token_type_t): Put OP_DUP_PLUS
among the tokens, rather than among the epsilon-transiting nodes.
(re_token_t): Add the opt_subexp flag.
* posix/regcomp.c (optimize_utf8, calc_first,
calc_next, calc_epsdest): Don't consider OP_DUP_PLUS.
(mark_opt_subexp, mark_opt_subexp_iter): New functions.
(parse_dup_op): Mostly rewritten, lowering OP_DUP_PLUS to
OP_DUP_ASTERISK and marking optional subexpressions
as such using mark_opt_subexp.
* posix/regexec.c (set_regs): Initialize PREV_INDEX_MATCH
and pass it to update_regs.
(update_regs): Use the PREV_INDEX_MATCH parameter, together
with the opt_subexp flag, in order to discard a final empty
match of a repeated subexpression.
* posix/BOOST.tests: Adjust test vectors.
* posix/PCRE.tests: Likewise.
* posix/rxspencer/tests: Likewise.
