From 202a4c37ee88e47c614a61db5fe0f134f9f6ea1a Mon Sep 17 00:00:00 2001 From: Giacomo Travaglini Date: Mon, 3 Dec 2018 11:37:51 +0000 Subject: ext: Build googlemock with googletest googlemock needs to be built together with googletest. This patch is enabling it by doing the following things * Moving googletest and googlemock under the same top level directory, so that we have a single SConscript for building them. This also matches googletest directory structure: googletest |_googletest |_googlemock * Adding a shared SConscript which is building gmock and gtest as libgtest * Removing googletest/SConscript Change-Id: I88accbdd2e80fb47efaa17819233371fbad6acaa Signed-off-by: Giacomo Travaglini Reviewed-by: Ciro Santilli Reviewed-by: Nikos Nikoleris Reviewed-on: https://gem5-review.googlesource.com/c/14696 Reviewed-by: Gabe Black Maintainer: Gabe Black --- .../test/gmock-generated-function-mockers_test.cc | 622 +++++++++++++++++++++ 1 file changed, 622 insertions(+) create mode 100644 ext/googletest/googlemock/test/gmock-generated-function-mockers_test.cc (limited to 'ext/googletest/googlemock/test/gmock-generated-function-mockers_test.cc') diff --git a/ext/googletest/googlemock/test/gmock-generated-function-mockers_test.cc b/ext/googletest/googlemock/test/gmock-generated-function-mockers_test.cc new file mode 100644 index 000000000..a86a61357 --- /dev/null +++ b/ext/googletest/googlemock/test/gmock-generated-function-mockers_test.cc @@ -0,0 +1,622 @@ +// Copyright 2007, Google Inc. +// All rights reserved. +// +// Redistribution and use in source and binary forms, with or without +// modification, are permitted provided that the following conditions are +// met: +// +// * Redistributions of source code must retain the above copyright +// notice, this list of conditions and the following disclaimer. +// * Redistributions in binary form must reproduce the above +// copyright notice, this list of conditions and the following disclaimer +// in the documentation and/or other materials provided with the +// distribution. +// * Neither the name of Google Inc. nor the names of its +// contributors may be used to endorse or promote products derived from +// this software without specific prior written permission. +// +// THIS SOFTWARE IS PROVIDED BY THE COPYRIGHT HOLDERS AND CONTRIBUTORS +// "AS IS" AND ANY EXPRESS OR IMPLIED WARRANTIES, INCLUDING, BUT NOT +// LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR +// A PARTICULAR PURPOSE ARE DISCLAIMED.
