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.
