From 0f6b172f72efea7cd99a9b790df75045f6c85dba Mon Sep 17 00:00:00 2001 From: Ulrich Drepper Date: Thu, 17 Aug 2000 19:36:13 +0000 Subject: [PATCH] Update. 2000-08-17 Ulrich Drepper * stdio-common/printf_fp.c: Fix chars_needed computation. Patch by Greg McGary . 2000-08-17 Jakub Jelinek * elf/dl-load.c (_dl_map_object): Don't crash if both loader and _dl_loaded are NULL. 2000-08-17 Jakub Jelinek * manual/arith.texi (feholdexcept): Returns 0 on success. 2000-08-17 Andreas Jaeger * sysdeps/gnu/net/if.h (struct ifreq): Add ifru_newname. (ifr_newname): New. Reported by Andi Kleen . 2000-08-17 Jakub Jelinek * sysdeps/alpha/fpu/fedisblxcpt.c: New file. * sysdeps/alpha/fpu/feenablxcpt.c: New file. * sysdeps/alpha/fpu/fegetexcept.c: New file. 2000-08-16 Jakub Jelinek * sysdeps/unix/sysv/linux/xstatconv.c (xstat32_conv): Test sizes of buf->st_ino and kbuf->st_ino, not __st_ino. If _HAVE_STAT64___ST_INO is not defined, don't use __st_ino at all. * sysdeps/unix/sysv/linux/getdents64.c: Change path in #include directive so that only linux/getdents.c is used, not some architecture specific one. 2000-08-16 Jakub Jelinek * sysdeps/i386/fpu/fegetexcept.c (fegetexcept): Return currently enabled, not disabled exceptions. * sysdeps/i386/fpu/fedisblxcpt.c (fedisableexcept): Likewise. * sysdeps/i386/fpu/feenablxcpt.c (feenableexcept): Likewise. ($(addprefix $(objpfx),$(tests)), $(addprefix $(objpfx),$(librt-tests))): * include/link.h: Undo last patches.
