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/lib/Support/Unix/RWMutex.inc | 50 ------------------------------- 1 file changed, 50 deletions(-) delete mode 100644 contrib/llvm/lib/Support/Unix/RWMutex.inc (limited to 'contrib/llvm/lib/Support/Unix/RWMutex.inc') diff --git a/contrib/llvm/lib/Support/Unix/RWMutex.inc b/contrib/llvm/lib/Support/Unix/RWMutex.inc deleted file mode 100644 index 8b47dfa0f85c..000000000000 --- a/contrib/llvm/lib/Support/Unix/RWMutex.inc +++ /dev/null @@ -1,50 +0,0 @@ -//= llvm/Support/Unix/RWMutex.inc - Unix Reader/Writer Mutual Exclusion Lock =// -// -// 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 Unix specific (non-pthread) RWMutex class. -// -//===----------------------------------------------------------------------===// - -//===----------------------------------------------------------------------===// -//=== WARNING: Implementation here must contain only generic UNIX code that -//=== is guaranteed to work on *all* UNIX variants. -//===----------------------------------------------------------------------===// - -#include "llvm/Support/Mutex.h" - -namespace llvm { - -using namespace sys; - -// This naive implementation treats readers the same as writers.
