From 27692f89660541896c591236fea9714e72b5a811 Mon Sep 17 00:00:00 2001 From: Ulrich Drepper Date: Sat, 24 Aug 2002 01:36:09 +0000 Subject: Update. * sysdeps/ieee754/dbl-64/e_pow.c (log1): Define and initialize two52 locally. (log2): Likewise. * sysdeps/ieee754/dbl-64/upow.h: Remove definition of two52. Patch by Simon Gee . * sysdeps/unix/sysv/linux/getsysstats.c (__get_nprocs_conf): Prefer reading /proc/stat since it is more uniform across architectures.1 * manual/texinfo.tex: Update to latest official version. --- sysdeps/unix/sysv/linux/getsysstats.c | 31 ++++++++++++++++++++++++++----- 1 file changed, 26 insertions(+), 5 deletions(-) (limited to 'sysdeps/unix/sysv') diff --git a/sysdeps/unix/sysv/linux/getsysstats.c b/sysdeps/unix/sysv/linux/getsysstats.c index bf39bd9661..f58e2e288a 100644 --- a/sysdeps/unix/sysv/linux/getsysstats.c +++ b/sysdeps/unix/sysv/linux/getsysstats.c @@ -1,5 +1,5 @@ /* Determine various system internal values, Linux version. - Copyright (C) 1996,1997,1998,1999,2000,2001 Free Software Foundation, Inc. + Copyright (C) 1996-2001, 2002 Free Software Foundation, Inc.
