From f67d78192c1be9d56d3a6f3fda4e0a70ae48c44d Mon Sep 17 00:00:00 2001 From: "Gabriel F. T. Gomes" Date: Tue, 13 Dec 2016 22:42:51 -0200 Subject: Move wrappers to libm-compat-calls-auto This commit moves one step towards the deprecation of wrappers that use _LIB_VERSION / matherr / __kernel_standard functionality, by adding the suffix '_compat' to their filenames and adjusting Makefiles and #includes accordingly. New template wrappers that do not use such functionality will be added by future patches and will be first used by the float128 wrappers. --- math/w_powf.c | 60 ----------------------------------------------------------- 1 file changed, 60 deletions(-) delete mode 100644 math/w_powf.c (limited to 'math/w_powf.c') diff --git a/math/w_powf.c b/math/w_powf.c deleted file mode 100644 index 7e3b015..0000000 --- a/math/w_powf.c +++ /dev/null @@ -1,60 +0,0 @@ -/* Copyright (C) 2011-2017 Free Software Foundation, Inc. - This file is part of the GNU C Library. - Contributed by Ulrich Drepper , 2011. - - 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.
