From 509bd8e35ad842944074e43cd2cc22381ee13f5b Mon Sep 17 00:00:00 2001 From: Ulrich Drepper Date: Tue, 21 May 2002 00:22:34 +0000 Subject: Update. 2002-05-20 Franz Sirl * sysdeps/powerpc/Makefile (sysdeps_routines): Use libgcc-compat instead of cmpdi2, shdi3, fixdfdi, fixsfdi in csu dir. (shared-only-routines): Likewise. * sysdeps/powerpc/libgcc-compat.c: New file. * sysdeps/wordsize-32/cmpdi2.c: Removed. * sysdeps/wordsize-32/fixdfdi.c: Removed. * sysdeps/wordsize-32/fixsfdi.c: Removed. * sysdeps/wordsize-32/shdi3.c: Removed. --- sysdeps/wordsize-32/cmpdi2.c | 95 -------------------------- sysdeps/wordsize-32/fixdfdi.c | 98 --------------------------- sysdeps/wordsize-32/fixsfdi.c | 102 ---------------------------- sysdeps/wordsize-32/shdi3.c | 150 ------------------------------------------ 4 files changed, 445 deletions(-) delete mode 100644 sysdeps/wordsize-32/cmpdi2.c delete mode 100644 sysdeps/wordsize-32/fixdfdi.c delete mode 100644 sysdeps/wordsize-32/fixsfdi.c delete mode 100644 sysdeps/wordsize-32/shdi3.c (limited to 'sysdeps/wordsize-32') diff --git a/sysdeps/wordsize-32/cmpdi2.c b/sysdeps/wordsize-32/cmpdi2.c deleted file mode 100644 index 720c66c460..0000000000 --- a/sysdeps/wordsize-32/cmpdi2.c +++ /dev/null @@ -1,95 +0,0 @@ -/* 64-bit integer comparison. - Copyright (C) 1989, 1992-2001, 2002 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 Lesser General Public - License as published by the Free Software Foundation; either - version 2.1 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.
