From fcdc67f963a44603553e52a0f883e5d0e5727b34 Mon Sep 17 00:00:00 2001 From: Roland McGrath Date: Fri, 20 Sep 2002 20:06:45 +0000 Subject: * sysdeps/powerpc/bits/setjmp.h [__WORDSIZE]: Add 64-bit jmpbuf. * sysdeps/powerpc/bits/wordsize.h: New file. * sysdeps/powerpc/fpu/bits/mathinline.h (lrint, lrintf): Change long array to int array for 32-/64-bit compatibility. 2002-09-20 Roland McGrath * login/programs/utmpdump.c: Don't include , . * sysdeps/generic/utimes.c (__utimes): Don't check TVP for null. Reported by Bruno Haible . * sysdeps/generic/ifreq.h (__ifreq): Compute termination condition before doubling RQ_LEN. * sysdeps/unix/sysv/linux/ifreq.h (__ifreq): Likewise. Reported by Bruno Haible . 2002-09-18 Bruno Haible * login/logout.c (logout): Don't assume ut_time has the same size as a time_t. * login/logwtmp.c (logwtmp): Likewise. * sysdeps/pthread/configure: New file, moved here from linuxthreads/sysdeps/unix/sysv/linux/configure. --- sysdeps/generic/ifreq.h | 5 ++--- sysdeps/generic/utimes.c | 4 ++-- sysdeps/powerpc/bits/setjmp.h | 19 +++++++++++++++---- sysdeps/powerpc/bits/wordsize.h | 7 +++++++ sysdeps/powerpc/fpu/bits/mathinline.h | 6 +++--- sysdeps/pthread/configure | 3 +++ sysdeps/unix/sysv/linux/ifreq.h | 9 ++++++--- 7 files changed, 38 insertions(+), 15 deletions(-) create mode 100644 sysdeps/powerpc/bits/wordsize.h create mode 100644 sysdeps/pthread/configure (limited to 'sysdeps') diff --git a/sysdeps/generic/ifreq.h b/sysdeps/generic/ifreq.h index c96d1c8789..f750065cd3 100644 --- a/sysdeps/generic/ifreq.h +++ b/sysdeps/generic/ifreq.h @@ -44,10 +44,10 @@ __ifreq (struct ifreq **ifreqs, int *num_ifs, int sockfd) } ifc.ifc_buf = NULL; - rq_len = RQ_IFS * sizeof (struct ifreq); + rq_len = RQ_IFS * sizeof (struct ifreq) / 2; /* Doubled in the loop. */ do { - ifc.ifc_len = rq_len; + ifc.ifc_len = rq_len *= 2; ifc.ifc_buf = realloc (ifc.ifc_buf, ifc.ifc_len); if (ifc.ifc_buf == NULL || __ioctl (fd, SIOCGIFCONF, &ifc) < 0) { @@ -60,7 +60,6 @@ __ifreq (struct ifreq **ifreqs, int *num_ifs, int sockfd) *ifreqs = NULL; return; } - rq_len *= 2; } while (rq_len < sizeof (struct ifreq) + ifc.ifc_len); diff --git a/sysdeps/generic/utimes.c b/sysdeps/generic/utimes.c index 67dd16c51b..e4a6f0427f 100644 --- a/sysdeps/generic/utimes.c +++ b/sysdeps/generic/utimes.c @@ -1,4 +1,4 @@ -/* Copyright (C) 1991, 1995, 1996, 1997, 2000 Free Software Foundation, Inc. +/* Copyright (C) 1991,95,96,97,2000,02 Free Software Foundation, Inc.
