From ea134f221f2a5c075b7539876a444b4a07362912 Mon Sep 17 00:00:00 2001 From: Benjamin Kramer Date: Wed, 7 Aug 2019 11:59:57 +0000 Subject: [Support] Base SmartMutex on std::recursive_mutex - Remove support for non-recursive mutexes. This was unused. - The std::recursive_mutex is now created/destroyed unconditionally. Locking is still only done if threading is enabled. - Alias SmartScopedLock to std::lock_guard. This should make no semantic difference on the existing APIs. llvm-svn: 368158 --- llvm/lib/Support/Windows/Mutex.inc | 56 -------------------------------------- 1 file changed, 56 deletions(-) delete mode 100644 llvm/lib/Support/Windows/Mutex.inc (limited to 'llvm/lib/Support/Windows/Mutex.inc') diff --git a/llvm/lib/Support/Windows/Mutex.inc b/llvm/lib/Support/Windows/Mutex.inc deleted file mode 100644 index b55b14febf2..00000000000 --- a/llvm/lib/Support/Windows/Mutex.inc +++ /dev/null @@ -1,56 +0,0 @@ -//===- llvm/Support/Win32/Mutex.inc - Win32 Mutex Implementation -*- C++ -*-===// -// -// Part of the LLVM Project, under the Apache License v2.0 with LLVM Exceptions. -// See https://llvm.org/LICENSE.txt for license information. -// SPDX-License-Identifier: Apache-2.0 WITH LLVM-exception -// -//===----------------------------------------------------------------------===// -// -// This file implements the Win32 specific (non-pthread) Mutex class. -// -//===----------------------------------------------------------------------===// - -//===----------------------------------------------------------------------===// -//=== WARNING: Implementation here must contain only generic Win32 code that -//=== is guaranteed to work on *all* Win32 variants. -//===----------------------------------------------------------------------===// - -#include "WindowsSupport.h" -#include "llvm/Support/Mutex.h" - -namespace llvm { - -sys::MutexImpl::MutexImpl(bool /*recursive*/) -{ - data_ = new CRITICAL_SECTION; - InitializeCriticalSection((LPCRITICAL_SECTION)data_); -} - -sys::MutexImpl::~MutexImpl() -{ - DeleteCriticalSection((LPCRITICAL_SECTION)data_); - delete (LPCRITICAL_SECTION)data_; - data_ = 0; -} - -bool -sys::MutexImpl::acquire() -{ - EnterCriticalSection((LPCRITICAL_SECTION)data_); - return true; -} - -bool -sys::MutexImpl::release() -{ - LeaveCriticalSection((LPCRITICAL_SECTION)data_); - return true; -} - -bool -sys::MutexImpl::tryacquire() -{ - return TryEnterCriticalSection((LPCRITICAL_SECTION)data_); -} - -} -- cgit v1.2.3
