From 1177c8babf74c7335c5f3bf09c45961bebeed6c6 Mon Sep 17 00:00:00 2001 From: Roland McGrath Date: Tue, 12 Mar 1996 09:50:46 +0000 Subject: Tue Mar 12 04:42:01 1996 Roland McGrath * sysdeps/sparc/jmp_buf.h: Rewritten; use array of ints, not struct. * sysdeps/sparc/setjmp.S: Rewritten; store %fp value as well. * sysdeps/sparc/__longjmp.S: Rewritten; unwind frames one by one with `restore' until the target frame is hit. Sun Mar 10 20:29:40 1996 Andreas Schwab * sysdeps/unix/sysv/linux/sigsuspend.c: New file. * sysdeps/unix/sysv/linux/syscalls.list: Remove sigsuspend, add s_sigsuspend. Thu Mar 7 21:30:58 1996 Andreas Schwab * Makerules (+make-deps, sed-remove-objpfx): Quote periods on the left side of sed substitutions. Sun Mar 10 16:58:10 1996 Ulrich Drepper * stdio-common/printf_fp.c (hack_digit): __mpn_normal_size is not available anymore. Do it ourselves. * sysdeps/unix/sysv/linux/i386/fpu_control.h (_FPU_SETCW): Correct GCC `asm' syntax. * stdio-common/Makefile (tests): Add tst-ungetc. * stdio-common/tst-ungetc.c: New test from drepper. * stdio-common/tstscanf.c (main): New %[ test case from drepper. * sysdeps/libm-ieee754/s_scalbn.c (scalbn): Rename to __scalbn; somehow this was missed, though the weak alias is already there. --- sysdeps/unix/sysv/linux/i386/fpu_control.h | 2 +- sysdeps/unix/sysv/linux/sigsuspend.c | 33 ++++++++++++++++++++++++++++++ sysdeps/unix/sysv/linux/syscalls.list | 2 +- 3 files changed, 35 insertions(+), 2 deletions(-) create mode 100644 sysdeps/unix/sysv/linux/sigsuspend.c (limited to 'sysdeps/unix') diff --git a/sysdeps/unix/sysv/linux/i386/fpu_control.h b/sysdeps/unix/sysv/linux/i386/fpu_control.h index ed56d83..8c04c1e 100644 --- a/sysdeps/unix/sysv/linux/i386/fpu_control.h +++ b/sysdeps/unix/sysv/linux/i386/fpu_control.h @@ -89,7 +89,7 @@ typedef unsigned int fpu_control_t __attribute__ ((__mode__ (__HI__))); /* Macros for accessing the hardware control word. */ #define _FPU_GETCW(cw) __asm__ ("fnstcw %0" : "=m" (cw)) -#define _FPU_SETCW(cw) __asm__ ("fldcw %0" : "m" (cw)) +#define _FPU_SETCW(cw) __asm__ ("fldcw %0" : : "m" (cw)) /* Default control word set at startup. */ extern fpu_control_t __fpu_control; diff --git a/sysdeps/unix/sysv/linux/sigsuspend.c b/sysdeps/unix/sysv/linux/sigsuspend.c new file mode 100644 index 0000000..53510b9 --- /dev/null +++ b/sysdeps/unix/sysv/linux/sigsuspend.c @@ -0,0 +1,33 @@ +/* Copyright (C) 1996 Free Software Foundation, Inc. +This file is part of the GNU C Library. + +The GNU C Library is free software; you can redistribute it and/or +modify it under the terms of the GNU Library General Public License as +published by the Free Software Foundation; either version 2 of the +License, or (at your option) any later version. + +The GNU C Library is distributed in the hope that it will be useful, +but WITHOUT ANY WARRANTY; without even the implied warranty of +MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
