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. --- .../llvm/lib/Support/ToolOutputFile.cpp | 45 ++++++++++++++++++++++ 1 file changed, 45 insertions(+) create mode 100644 contrib/llvm-project/llvm/lib/Support/ToolOutputFile.cpp (limited to 'contrib/llvm-project/llvm/lib/Support/ToolOutputFile.cpp') diff --git a/contrib/llvm-project/llvm/lib/Support/ToolOutputFile.cpp b/contrib/llvm-project/llvm/lib/Support/ToolOutputFile.cpp new file mode 100644 index 000000000000..ed3a247f0115 --- /dev/null +++ b/contrib/llvm-project/llvm/lib/Support/ToolOutputFile.cpp @@ -0,0 +1,45 @@ +//===--- ToolOutputFile.cpp - Implement the ToolOutputFile class --------===// +// +// 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 implements the ToolOutputFile class. +// +//===----------------------------------------------------------------------===// + +#include "llvm/Support/ToolOutputFile.h" +#include "llvm/Support/FileSystem.h" +#include "llvm/Support/Signals.h" +using namespace llvm; + +ToolOutputFile::CleanupInstaller::CleanupInstaller(StringRef Filename) + : Filename(Filename), Keep(false) { + // Arrange for the file to be deleted if the process is killed. + if (Filename != "-") + sys::RemoveFileOnSignal(Filename); +} + +ToolOutputFile::CleanupInstaller::~CleanupInstaller() { + // Delete the file if the client hasn't told us not to. + if (!Keep && Filename != "-") + sys::fs::remove(Filename); + + // Ok, the file is successfully written and closed, or deleted.
