From 2020748d8efb7fbadd43a49cc3859dcf4a93472e Mon Sep 17 00:00:00 2001 From: Joseph Myers Date: Tue, 13 Oct 2015 16:53:09 +0000 Subject: Move powerpc llround implementations to powerpc32 directory. sysdeps/powerpc/fpu/ has versions of llround and llroundf that are actually used only for powerpc32 because sysdeps/powerpc/powerpc64/fpu/ has its own versions of those functions. This patch moves them into sysdeps/powerpc/powerpc32/fpu to reflect where they are actually used (in preparation for fixing other problems with those functions). Tested for powerpc that installed stripped shared libraries are unchanged by this patch. * sysdeps/powerpc/fpu/s_llround.c: Move to .... * sysdeps/powerpc/powerpc32/fpu/s_llround.c: ...here. * sysdeps/powerpc/fpu/s_llroundf.c: Move to .... * sysdeps/powerpc/powerpc32/fpu/s_llroundf.c: ...here. --- sysdeps/powerpc/powerpc32/fpu/s_llround.c | 52 ++++++++++++++++++++++++++++++ sysdeps/powerpc/powerpc32/fpu/s_llroundf.c | 44 +++++++++++++++++++++++++ 2 files changed, 96 insertions(+) create mode 100644 sysdeps/powerpc/powerpc32/fpu/s_llround.c create mode 100644 sysdeps/powerpc/powerpc32/fpu/s_llroundf.c (limited to 'sysdeps/powerpc/powerpc32/fpu') diff --git a/sysdeps/powerpc/powerpc32/fpu/s_llround.c b/sysdeps/powerpc/powerpc32/fpu/s_llround.c new file mode 100644 index 0000000000..85514a1d3f --- /dev/null +++ b/sysdeps/powerpc/powerpc32/fpu/s_llround.c @@ -0,0 +1,52 @@ +/* Round double value to long long int. + Copyright (C) 1997-2015 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.
