* malloc/hooks.c (realloc_check): If mremap succeeds actually use the result. * sysdeps/i386/i486/bits/string.h: Add early clobber for "a" output parameter. Reported by Denis Zaitsev <zzz@cd-club.ru>. * Versions.def (libthread_db): Add GLIBC_2.3. 2002-07-09 Jakub Jelinek <jakub@redhat.com> * libio/freopen.c (freopen): Reset jump tables, use mmap stdio for the new stream if possible. * libio/freopen64.c (freopen64): Likewise. * libio/Makefile (tests): Add tst-freopen. * libio/tst-freopen.c: New file. 2002-07-03 Jakub Jelinek <jakub@redhat.com> * libio/stdio.h (obstack_printf): Add format attribute. (obstack_vprintf): Likewise. 2002-07-04 Jakub Jelinek <jakub@redhat.com> * posix/regex_internal.h (re_token_t): Shrink the structure to 8 resp. 16 bytes on 32-bit resp. 64-bit platforms. (re_charset_t, re_string_t): Reorder structure members for 64-bit architectures. 2002-07-04 Jakub Jelinek <jakub@redhat.com> * posix/regcomp.c (re_compile_internal): Move clearing of dfa... (init_dfa): ...here. 2002-07-05 Isamu Hasegawa <isamu@yamato.ibm.com> * posix/regcomp.c (parse_sub_exp): Add nodes OP_OPEN_SUBEXP and OP_CLOSE_SUBEXP at both ends of sub expressions instead of SUBEXP nodes in parse trees. (calc_first): Fix the Definition of `firsts' of OP_OPEN_SUBEXP and OP_CLOSE_SUBEXP, and remove the definition of SUBEXP. (calc_epsdest): Treat OP_OPEN_SUBEXP and OP_CLOSE_SUBEXP as the nodes which can epsilon transit. * posix/regex_internal.h: Add OP_OPEN_SUBEXP and OP_CLOSE_SUBEXP to IS_EPSILON_NODE macro. * posix/regexec.c (update_regs): New function to update registers by refering OP_OPEN_SUBEXP and OP_CLOSE_SUBEXP nodes. (proceed_next_node): Use the entities of the nodes to determine whether the node can transit to. (set_regs): Use update_regs function to update registers. 2002-07-03 Jakub Jelinek <jakub@redhat.com> * posix/bug-regex4.c (main): Remove duplicate setlocale. * posix/bug-regex6.c: New file. * posix/Makefile (tests): Add bug-regex6. (bug-regex6-ENV): Set LOCPATH. 2002-07-10 Ulrich Drepper <drepper@redhat.com>
