From dcf241189ab7eb060aeb06caad8b14aa964f6736 Mon Sep 17 00:00:00 2001 From: Joakim Tjernlund Date: Mon, 12 Feb 2007 21:57:57 +0000 Subject: Rehash the PowerPC e500 port to avoid creating symlinks in the powerpc arch code and make more code common with classic PowerPC. From Steve Papacharalambous Lets hope I didn't break something. --- libc/sysdeps/linux/powerpc/bits/e500/fenv.h | 79 ----------------------------- 1 file changed, 79 deletions(-) delete mode 100644 libc/sysdeps/linux/powerpc/bits/e500/fenv.h (limited to 'libc/sysdeps/linux/powerpc/bits/e500/fenv.h') diff --git a/libc/sysdeps/linux/powerpc/bits/e500/fenv.h b/libc/sysdeps/linux/powerpc/bits/e500/fenv.h deleted file mode 100644 index 41963da38..000000000 --- a/libc/sysdeps/linux/powerpc/bits/e500/fenv.h +++ /dev/null @@ -1,79 +0,0 @@ -/* Copyright (C) 2004 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.
