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.
