From 3ef6b85059cdd52096625d98c4ce9259854cb8bb Mon Sep 17 00:00:00 2001 From: Stefan Liebler Date: Fri, 20 Jun 2014 07:48:20 +0530 Subject: [BZ #6803] Set errno for scalbln, scalbn Errno is not set and the testcases will fail. Now the scalbln-aliases are removed in i386/m68 and the wrappers are used when calling the scalbln-functions. On ia64 only scalblnf has its own implementation. For scalbln and scalblnl the ieee754/dbl-64 and ieee754/ldbl-96 are used, thus the wrappers are needed, too. --- math/w_scalblnl.c | 36 ++++++++++++++++++++++++++++++++++++ 1 file changed, 36 insertions(+) create mode 100644 math/w_scalblnl.c (limited to 'math/w_scalblnl.c') diff --git a/math/w_scalblnl.c b/math/w_scalblnl.c new file mode 100644 index 0000000000..48504e0239 --- /dev/null +++ b/math/w_scalblnl.c @@ -0,0 +1,36 @@ +/* Wrapper for __scalblnl handles setting errno. + Copyright (C) 2014 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.
