From 510ca033d66c47e0dc54550928dece59799a0136 Mon Sep 17 00:00:00 2001 From: Roland McGrath Date: Thu, 23 May 1996 05:33:49 +0000 Subject: Wed May 22 00:40:50 1996 David Mosberger-Tang * sysdeps/unix/sysv/linux/alpha/speed.c (speeds): Add entry for 460800 baud. * sysdeps/unix/sysv/linux/alpha/statbuf.h: New file. * sysdeps/unix/sysv/linux/Makefile (headers): Add alpha/ptrace.h. * sysdeps/unix/sysv/linux/alpha/alpha/ptrace.h: New file. * sysdeps/libm-ieee754/s_scalbnf.c: Call __scalbnf instead of scalbnf. * sysdeps/generic/sigset.h (__sigismember, __sigaddset, __sigdelset): Add declaration to keep ANSI compilers quiet. * sysdeps/alpha/__math.h (cabs): Remove underscores from struct __cabs_complex member names in call to __hypot(). * sysdeps/alpha/copysign.S, sysdeps/alpha/fabs.S: New files. * sysdeps/alpha/divrem.h: Renamed from sysdeps/alpha/divrem.S to avoid name collision with math library. * sysdeps/alpha/divl.S, sysdeps/alpha/divlu.S, sysdeps/alpha/divq.S, sysdeps/alpha/divqu.S, sysdeps/alpha/reml.S, sysdeps/alpha/remlu.S, sysdeps/alpha/remq.S, sysdeps/alpha/remqu.S: Include divrem.h instead of divrem.S. * sysdeps/unix/alpha/sysdep.h: Include regdef.h. Define LEAF macro to simplify declaration of leaf functions. * sysdeps/alpha/_mcount.S, sysdeps/alpha/bb_init_func.S, sysdeps/alpha/bsd-setjmp.S, sysdeps/alpha/ffs.S, sysdeps/alpha/htonl.S, sysdeps/alpha/htons.S, sysdeps/alpha/memchr.S, sysdeps/alpha/setjmp.S, sysdeps/alpha/strlen.S, sysdeps/alpha/udiv_qrnnd.S, sysdeps/unix/sysv/linux/alpha/brk.S, sysdeps/unix/sysv/linux/alpha/ieee_get_fp_control.S, sysdeps/unix/sysv/linux/alpha/ieee_set_fp_control.S, sysdeps/unix/sysv/linux/alpha/pipe.S, sysdeps/unix/sysv/linux/sigsuspend.S, sysdeps/unix/sysv/linux/alpha/syscall.S, sysdeps/unix/sysv/linux/alpha/sysdep.S: Remove include of regdef.h. sysdep.h includes it now. Replace ENTRY by LEAF with appropriate framesize declaration. Replace "lda pv,sym/jsr pv" by "jsr sym". * sysdeps/unix/sysv/linux/alpha/sysdep.h (NO_UNDERSCORES): Don't define. * sysdeps/unix/sysv/linux/alpha/syscalls.list: Added getsockopt, ptrace, and sysctl. * sysdeps/unix/sysv/linux/alpha/profil-counter.h: File removed. * sysdeps/unix/sysv/linux/alpha/ioperm.c: Modify to support dynamic recognition of platform type. (_bus_base): New function. * sysdeps/unix/sysv/linux/alpha/llseek.S: New file. * sunrpc/rpc/rpc.h, sunrpc/rpc/svc.h: Avoid nested comments since they produce ugly warnings by gcc. * posix/sys/types.h [__USE_MISC]: Add typedef for ulong. Wed Mar 27 10:26:21 1996 David Mosberger-Tang * sysdeps/alpha/setjmp.S: Must establish global pointer before address of __sigsetjmp_aux can be loaded. --- sysdeps/unix/sysv/linux/alpha/syscall.S | 25 ++++++++++++------------- 1 file changed, 12 insertions(+), 13 deletions(-) (limited to 'sysdeps/unix/sysv/linux/alpha/syscall.S') diff --git a/sysdeps/unix/sysv/linux/alpha/syscall.S b/sysdeps/unix/sysv/linux/alpha/syscall.S index 54a8484c58..c80a523239 100644 --- a/sysdeps/unix/sysv/linux/alpha/syscall.S +++ b/sysdeps/unix/sysv/linux/alpha/syscall.S @@ -41,21 +41,20 @@ Cambridge, MA 02139, USA. */ */ -1: br gp,2f -2: ldgp gp,0(gp) - jmp zero,syscall_error - - -ENTRY (__syscall) - bis a0,a0,v0 # Syscall number -> v0 - bis a1,a1,a0 # arg1-arg5 -> a0-a4 - bis a2,a2,a1 - bis a3,a3,a2 - bis a4,a4,a3 - bis a5,a5,a4 +LEAF(__syscall, 0) + bis a0, a0, v0 # Syscall number -> v0 + bis a1, a1, a0 # arg1-arg5 -> a0-a4 + bis a2, a2, a1 + bis a3, a3, a2 + bis a4, a4, a3 + bis a5, a5, a4 call_pal PAL_callsys # Invoke system call - bne a3,1b + bne a3, error ret +error: br gp, 2f +2: ldgp gp, 0(gp) + jmp zero, syscall_error + weak_alias(__syscall, syscall) -- cgit v1.2.3
