Update.
2003-01-06 Philip Blundell <philb@gnu.org>
* sysdeps/unix/arm/sysdep.S (syscall_error): Optimise a little.
[__LIBC_REENTRANT]: Unify PIC and non-PIC cases.
* sysdeps/unix/sysv/linux/arm/sysdep.h (PSEUDO): Remove .type
directive.
(PSEUDO_RET): Use SYSCALL_ERROR in place of __syscall_error.
(SYSCALL_ERROR): New.
(SYSCALL_ERROR_HANDLER) [NOT_IN_libc]: Provide local copy of error
handling code.
(INTERNAL_SYSCALL): Define.
(INLINE_SYSCALL): Use it.
(INTERNAL_SYSCALL_ERROR_P, INTERNAL_SYSCALL_ERRNO): Define.
* sysdeps/unix/sysv/linux/arm/socket.S (__socket): Use
SYSCALL_ERROR in place of __syscall_error.
2003-01-07 Jakub Jelinek <jakub@redhat.com>
* sysdeps/ia64/bits/byteswap.h [__GNUC__ >= 2] (__bswap_16,
__bswap_32, __bswap_64): Put x into temporary variable
to avoid warnings.
[!__GNUC__] (__bswap_16, __bswap_32, __bswap_64): Change into static
(inline) functions.
* sysdeps/s390/bits/byteswap.h [__GNUC__ >= 2] (__bswap_16,
__bswap_32, __bswap_64): Put x into temporary variable
to avoid warnings.
[!__GNUC__] (__bswap_16, __bswap_32, __bswap_64): Change into static
(inline) functions.
* sysdeps/i386/bits/byteswap.h [!__GNUC__] (__bswap_16, __bswap_32):
Likewise.
2003-01-07 Jakub Jelinek <jakub@redhat.com>
* sysdeps/unix/sysv/linux/alpha/adjtime.c (ntp_adjtime): New weak
alias.
