From: Richard Henderson Most of the patch concerns kernel-features.h, and using it in some syscalls added before 2.2.0. Some new usage of INLINE_SYSCALL in various places. 2003-06-20 Richard Henderson linuxthreads/ * sysdeps/unix/sysv/linux/alpha/Makefile (libpthread-routines): Remove ptw-osf_sigprocmask. libc/ * sysdeps/unix/alpha/sysdep.h (INLINE_SYSCALL1): Use __builtin_expect. * sysdeps/unix/sysv/linux/kernel-features.h (__ASSUME_ST_INO_64_BIT) Unset for alpha. (__ASSUME_TIMEVAL64): Set for alpha. * sysdeps/unix/sysv/linux/alpha/Makefile (sysdep_routines): Remove adjtimex, osf_sigprocmask, old_adjtimex. * sysdeps/unix/sysv/linux/alpha/adjtime.c: Use INLINE_SYSCALL, __ASSUME_TIMEVAL64. Reorg tv64 functions to avoid uninit variable. * sysdeps/unix/sysv/linux/alpha/getitimer.S: Use __ASSUME_TIMEVAL64. * 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/ieee_get_fp_control.S: Streamline PIC code sequence. * sysdeps/unix/sysv/linux/alpha/ieee_set_fp_control.S: Likewise. * sysdeps/unix/sysv/linux/alpha/sigaction.c: New file. * sysdeps/unix/sysv/linux/alpha/sigprocmask.c: Use INLINE_SYSCALL. * sysdeps/unix/sysv/linux/alpha/ustat.c: Likewise. * sysdeps/unix/sysv/linux/alpha/xmknod.c: Likewise. * sysdeps/unix/sysv/linux/alpha/syscalls.list: Remove osf_sigprocmask, sys_ustat, sys_mknod, adjtimex, old_adjtimex. * sysdeps/unix/sysv/linux/alpha/sysdep.h (INLINE_SYSCALL): Don't defer to __syscall_name; error for rt_sigaction. * sysdeps/unix/sysv/linux/alpha/xstatconv.c: Include kernel_stat.h.
