From 0b57cec536236d46e3dba9bd041533462f33dbb7 Mon Sep 17 00:00:00 2001 From: Dimitry Andric Date: Fri, 20 Dec 2019 19:53:05 +0000 Subject: Move all sources from the llvm project into contrib/llvm-project. This uses the new layout of the upstream repository, which was recently migrated to GitHub, and converted into a "monorepo". That is, most of the earlier separate sub-projects with their own branches and tags were consolidated into one top-level directory, and are now branched and tagged together. Updating the vendor area to match this layout is next. --- contrib/llvm-project/llvm/lib/Support/Memory.cpp | 53 ++++++++++++++++++++++++ 1 file changed, 53 insertions(+) create mode 100644 contrib/llvm-project/llvm/lib/Support/Memory.cpp (limited to 'contrib/llvm-project/llvm/lib/Support/Memory.cpp') diff --git a/contrib/llvm-project/llvm/lib/Support/Memory.cpp b/contrib/llvm-project/llvm/lib/Support/Memory.cpp new file mode 100644 index 000000000000..581484268cd8 --- /dev/null +++ b/contrib/llvm-project/llvm/lib/Support/Memory.cpp @@ -0,0 +1,53 @@ +//===- Memory.cpp - Memory Handling Support ---------------------*- 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 defines some helpful functions for allocating memory and dealing +// with memory mapped files +// +//===----------------------------------------------------------------------===// + +#include "llvm/Support/Memory.h" +#include "llvm/Config/llvm-config.h" +#include "llvm/Support/Valgrind.h" + +#ifndef NDEBUG +#include "llvm/Support/raw_ostream.h" +#endif // ifndef NDEBUG + +// Include the platform-specific parts of this class. +#ifdef LLVM_ON_UNIX +#include "Unix/Memory.inc" +#endif +#ifdef _WIN32 +#include "Windows/Memory.inc" +#endif + +#ifndef NDEBUG + +namespace llvm { +namespace sys { + +raw_ostream &operator<<(raw_ostream &OS, const Memory::ProtectionFlags &PF) { + assert((PF & ~(Memory::MF_READ | Memory::MF_WRITE | Memory::MF_EXEC)) == 0 && + "Unrecognized flags"); + + return OS << (PF & Memory::MF_READ ?
