From feb62ddacb7b1d772d7383de0228a3977f07fc1e Mon Sep 17 00:00:00 2001 From: "Paul E. Murphy" Date: Tue, 28 Jun 2016 14:28:04 -0500 Subject: Convert remaining complex function to generated files Convert cpow, clog, clog10, cexp, csqrt, and cproj functions into generated templates. Note, ldbl-opt still retains s_clog10l.c as the aliasing rules are non-trivial. --- math/s_clog10.c | 124 -------------------------------------------------------- 1 file changed, 124 deletions(-) delete mode 100644 math/s_clog10.c (limited to 'math/s_clog10.c') diff --git a/math/s_clog10.c b/math/s_clog10.c deleted file mode 100644 index 8d9245bac6..0000000000 --- a/math/s_clog10.c +++ /dev/null @@ -1,124 +0,0 @@ -/* Compute complex base 10 logarithm. - Copyright (C) 1997-2016 Free Software Foundation, Inc. - This file is part of the GNU C Library. - Contributed by Ulrich Drepper , 1997. - - 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.
