1998-02-24 08:10 H.J. Lu <hjl@gnu.org> * sysdeps/unix/sysv/linux/alpha/bits/signum.h (_NSIG): Changed to 64. * sysdeps/unix/alpha/sysdep.S (_errno): Add in addition to __errno. * sysdeps/alpha/s_fabs.S: Added ".set noat"/".set at". * sysdeps/unix/sysv/linux/alpha/wait4.S: Ditto. * sysdeps/unix/make-syscalls.sh: Make versioned symbols only for shared library. * libc.map (adjtime, __adjtimex, adjtimex): Added for GLIBC_2.1. * sysdeps/unix/sysv/linux/alpha/Makefile (sysdep_routines): Added adjtimex and old_adjtimex. * sysdeps/unix/sysv/linux/alpha/syscalls.list (old_adjtimex): New. (osf_settimeofday, osf_getitimer, osf_setitimer, osf_utimes, osf_getrusage, osf_wait4): Added __xxxx symbol for GLIBC_2.0. * sysdeps/unix/sysv/linux/alpha/getitimer.S: Make versioned symbols only for shared library. * sysdeps/unix/sysv/linux/alpha/getrusage.S: Likewise. * sysdeps/unix/sysv/linux/alpha/gettimeofday.S: Likewise. * sysdeps/unix/sysv/linux/alpha/select.S: Likewise. * sysdeps/unix/sysv/linux/alpha/setitimer.S: Likewise. * sysdeps/unix/sysv/linux/alpha/settimeofday.S: Likewise. * sysdeps/unix/sysv/linux/alpha/utimes.S: Likewise. * sysdeps/unix/sysv/linux/alpha/wait4.S: Likewise. * sysdeps/unix/sysv/linux/alpha/getitimer.S: Fix ENOSYS branch. * sysdeps/unix/sysv/linux/alpha/getrusage.S: Likewise. * sysdeps/unix/sysv/linux/alpha/gettimeofday.S: Likewise. * sysdeps/unix/sysv/linux/alpha/select.S: Likewise. * sysdeps/unix/sysv/linux/alpha/setitimer.S: Likewise. * sysdeps/unix/sysv/linux/alpha/settimeofday.S: Likewise. * sysdeps/unix/sysv/linux/alpha/utimes.S: Likewise. * sysdeps/unix/sysv/linux/alpha/wait4.S: Likewise. * sysdeps/unix/sysv/linux/alpha/wait4.S: Check the correct rusage pointer. * sysdeps/unix/sysv/linux/adjtime.c (TIMEVAL, TIMEX, ADJTIMEX): New macros. (__adjtime): Use TIMEVAL, TIMEX and ADJTIMEX instead of timeval, timex and __adjtimex, respectively. * sysdeps/unix/sysv/linux/alpha/adjtime.c: New. * sysdeps/unix/sysv/linux/alpha/adjtimex.S: New.
