Update.
2002-02-07 Andreas Schwab <schwab@suse.de>
* configure.in: Fix check for -zcombreloc.
2002-02-06 H.J. Lu <hjl@gnu.org>
* config.h.in (HAVE_BUILTIN_MEMSET): New.
* configure.in: Check if __builtin_memset really works.
* elf/rtld.c (_dl_start): Check HAVE_BUILTIN_MEMSET instead of
__GNUC_PREREQ (2, 96) before using __builtin_memset.
2002-02-06 Jakub Jelinek <jakub@redhat.com>
* io/bug-ftw3.c (main): Don't try the test if root.
2002-02-06 Martin Schwidefsky <schwidefsky@de.ibm.com>
* sysdeps/unix/sysv/linux/s390/brk.c (__brk): Correct inline assembly
constraints.
* sysdeps/unix/sysv/linux/s390/s390-32/bits/resource.h (RLIMIT_LOCKS):
Add RLIMIT_LOCKS and adjust RLIMIT_NLIMITS.
* sysdeps/unix/sysv/linux/s390/s390-64/bits/resource.h (RLIMIT_LOCKS):
Likewise.
* sysdeps/unix/sysv/linux/s390/s390-32/clone.S (clone): Make clone
a weak alias for __clone.
* sysdeps/unix/sysv/linux/s390/s390-64/clone.S (clone): Likewise.
* sysdeps/unix/sysv/linux/s390/s390-32/profil-counter.h: Fix typo.
* sysdeps/unix/sysv/linux/s390/s390-64/Makefile: Add framestate.
* sysdeps/unix/sysv/linux/s390/s390-64/Versions: New file.
* sysdeps/unix/sysv/linux/s390/s390-64/mmap.S (__mmap64): Make __mmap
a weak alias for __mmap64.
* sysdeps/mips/atomicity.h (exchange_and_add): Not use branch likely.
* sysdeps/unix/sysv/linux/mips/sys/tas.h (_test_and_set): Likewise.
* sysdeps/generic/dl-tls.c: Don't read TLS header if TLS is not needed.
