From 25597bdfc148e91e27678ec30efa52f4fc8c164f Mon Sep 17 00:00:00 2001 From: Abseil Team Date: Wed, 2 Oct 2019 15:20:57 -0700 Subject: Export of internal Abseil changes -- 3e60f355db5afd7a864591d81a6c383b6c0a0780 by Samuel Benzaquen : Internal change PiperOrigin-RevId: 272531442 -- 6d189240b8cebe3a390c730de491156d03049229 by Andy Getzendanner : Fix AtomicHook init-order fiasco under MSVC 2019. On this platform, constexpr static init sometimes happens after dynamic init =/. When it does, we should not zero hook_ (overwriting the value written there by dynamic init); instead we should leave it alone. This works even when constexpr static init goes first since all uses of AtomicHook should have static storage duration and be zero-initialized. https://developercommunity.visualstudio.com/content/problem/336946/class-with-constexpr-constructor-not-using-static.html PiperOrigin-RevId: 272525226 -- d01b14fc06bc75b41c51976ed32e7c304ea1aab7 by Abseil Team : exclude emscripten from running tests involving long doubles PiperOrigin-RevId: 272497628 GitOrigin-RevId: 3e60f355db5afd7a864591d81a6c383b6c0a0780 Change-Id: I3c8a8f5acaf7652a06ef40cf028ef5d2e142f81b --- absl/base/internal/atomic_hook_test_helper.cc | 29 +++++++++++++++++++++++++++ 1 file changed, 29 insertions(+) create mode 100644 absl/base/internal/atomic_hook_test_helper.cc (limited to 'absl/base/internal/atomic_hook_test_helper.cc') diff --git a/absl/base/internal/atomic_hook_test_helper.cc b/absl/base/internal/atomic_hook_test_helper.cc new file mode 100644 index 00000000..fad7a89a --- /dev/null +++ b/absl/base/internal/atomic_hook_test_helper.cc @@ -0,0 +1,29 @@ +// Copyright 2017 The Abseil Authors. +// +// Licensed under the Apache License, Version 2.0 (the "License"); +// you may not use this file except in compliance with the License. +// You may obtain a copy of the License at +// +// https://www.apache.org/licenses/LICENSE-2.0 +// +// Unless required by applicable law or agreed to in writing, software +// distributed under the License is distributed on an "AS IS" BASIS, +// WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. +// See the License for the specific language governing permissions and +// limitations under the License. + +#include "absl/base/internal/atomic_hook_test_helper.h" + +#include "absl/base/attributes.h" +#include "absl/base/internal/atomic_hook.h" + +namespace absl { +namespace atomic_hook_internal { + +ABSL_CONST_INIT absl::base_internal::AtomicHook func(DefaultFunc); +ABSL_CONST_INIT int default_func_calls = 0; +void DefaultFunc() { default_func_calls++; } +void RegisterFunc(VoidF f) { func.Store(f); } + +} // namespace atomic_hook_internal +} // namespace absl -- cgit v1.2.3
