+ regex: merge glibc changes
+
+ * lib/regcomp.c (init_dfa): Tighten overflow checks to test
+ for IDX_MAX too, since IDX_MAX can be much less than SIZE_MAX.
+ (init_word_char): Work even if bitset words are not exactly 32 or
+ 64 bits wide. Don't assume there are no padding bits.
+ * lib/regex.c [_LIBC]: Do not include <config.h>.
+ [!_LIBC]: Add pragmas to ignore -Wsuggest-attributes=pure
+ and -Wtype-limits.
+ * lib/regex.h (__USE_GNU): Renamed from __USE_GNU_REGEX, to avoid
+ needless disagreement with glibc. All uses changed. Define it to
+ 1 only if _GNU_SOURCE, to match glibc.
+ (_REG_RM_NAME): Remove; no longer needed, since the names in
+ question are now all protected by __USE_GNU.
+ (_REG_RE_NAME): Remove; replaced by glibc's __REPB_PREFIX.
+ (REG_TRANSLATE_TYPE): Remove; replaced by glibc's __RE_TRANSLATE_TYPE.
+ * lib/regex_internal.h (MIN): New macro.
+
+ 2012-01-03 Ulrich Drepper <drepper@gmail.com>
+ * lib/regcomp.c (init_word_char): Optimize regex a bit.
+
+ 2011-12-30 Jakub Jelinek <jakub@redhat.com>
+ * lib/regex_internal.c (re_string_fetch_byte_case):
+ Fix up regcomp/regexec. The problem is that parse_bracket_symbol
+ is miscompiled, and it turns out it is because of an incorrect
+ attribute on re_string_fetch_byte_case. Unlike
+ re_string_peek_byte_case, this one is really not pure, it modifies
+ memory (increments pstr->cur_idx), and with the pure attribute GCC
+ assumed it doesn't and it cached the presumed value of
+ regexp->cur_idx in a variable across the
+ for (;; ++i)
+ {
+ if (i >= BRACKET_NAME_BUF_SIZE)
+ return REG_EBRACK;
+ if (token->type == OP_OPEN_CHAR_CLASS)
+ ch = re_string_fetch_byte_case (regexp);
+ else
+ ch = re_string_fetch_byte (regexp);
+ if (re_string_eoi(regexp))
+ return REG_EBRACK;
+ if (ch == delim && re_string_peek_byte (regexp, 0) == ']')
+ break;
+ elem->opr.name[i] = ch;
+ }

+ * lib/regcomp.c (build_equiv_class):
+ Fix access after end of search string in regex matcher.
+
+ 2011-11-12 Ulrich Drepper <drepper@redhat.com>
+ * lib/regex_internal.c, lib/regex_internal.h: Fix warnings in regex.
+
+ 2011-10-12 Ulrich Drepper <drepper@redhat.com>
+ * lib/regcomp.c (parse_branch): One more regex memory leak fixed.
+
+ 2011-10-11 Ulrich Drepper <drepper@redhat.com>
+ * lib/regcomp.c (parse_branch, parse_sub_exp):
+ More regex memory leak fixes and tests.
+ (parse_sub_exp, parse_bracket_exp):
+ Fix memory leak for some invalid regular expressions.
+
+ 2011-05-28 Ulrich Drepper <drepper@gmail.com>
+ * lib/regex_internal.c, lib/regexec.c:
+ Fix unnecessary overallocation due to incomplete character. When
+ incomplete characters are found at the end of a string the code
+ ran amok and allocated lots of memory. Stricter limits are now in
+ place.
+
+ 2011-05-20 Reuben Thomas <rrt@sc3d.org>
+ * lib/regex.h: Update documentation.
+
+ 2011-05-16 Aharon Robbins <arnold@skeeve.com>
+ * lib/regex.h: Update RE_SYNTAX*_AWK constants.
+
+ 2010-05-05 Andreas Schwab <schwab@redhat.com>
+ * lib/regexec.c (find_collation_sequence_value):
+ Fix lookup of collation sequence value during regexp matching.
+
+ 2010-01-22 Ulrich Drepper <drepper@redhat.com>
+ * lib/regex_internal.c (re_dfa_add_node): Extend overflow detection.
+
+ 2008-01-16 Ulrich Drepper <drepper@redhat.com>
+ * lib/regex.h: Cleanup namespace.
+
+ 2007-11-26 Ulrich Drepper <drepper@redhat.com>
+ * lib/regex.h (REG_ENOSYS): Define REG_ENOSYS also for __USE_XOPEN2K.
+
+ 2007-08-26 Ulrich Drepper <drepper@redhat.com>
+ * lib/regex_internal.h: Prevent some declarations and definitions
+ to be seen when used in tests.
+
+ 2005-05-06 Ulrich Drepper <drepper@redhat.com>
+ * lib/regex_internal.h: Include bits/libc-lock.h or define dummy
+ __libc_lock_* macros if not _LIBC.
+ (struct re_dfa_t): Add lock.
