From eb8f4500719b52f410c545f738d8fda399cea587 Mon Sep 17 00:00:00 2001 From: Gael Guennebaud Date: Fri, 20 Nov 2009 15:39:38 +0100 Subject: Hey, finally the copyCoeff stuff is not only used to implement swap anymore :) Add an internal pseudo expression allowing to optimize operators like +=, *= using the copyCoeff stuff. This allows to easily enforce aligned load for the destination matrix everywhere. --- test/unalignedcount.cpp | 56 +++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 56 insertions(+) create mode 100644 test/unalignedcount.cpp (limited to 'test/unalignedcount.cpp') diff --git a/test/unalignedcount.cpp b/test/unalignedcount.cpp new file mode 100644 index 000000000..feff870e5 --- /dev/null +++ b/test/unalignedcount.cpp @@ -0,0 +1,56 @@ +// This file is part of Eigen, a lightweight C++ template library +// for linear algebra. +// +// Copyright (C) 2009 Gael Guennebaud +// +// Eigen 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 3 of the License, or (at your option) any later version. +// +// Alternatively, you can redistribute it and/or +// modify it under the terms of the GNU General Public License as +// published by the Free Software Foundation; either version 2 of +// the License, or (at your option) any later version. +// +// Eigen 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.
