From 504f3844aec477f31d9640b90dfd5b0e2a773d7e Mon Sep 17 00:00:00 2001 From: Pavel Labath Date: Wed, 19 Oct 2016 17:17:53 +0000 Subject: Revert "Add Chrono.h - std::chrono support header" This reverts commit r284590 as it fails on the mingw buildbot. I think I know the fix, but I cannot test it right now. Will reapply when I verify it works ok. This reverts r284590. llvm-svn: 284615 --- llvm/lib/Support/Unix/TimeValue.inc | 54 +++++++++++++++++++++++++++++++++++++ 1 file changed, 54 insertions(+) create mode 100644 llvm/lib/Support/Unix/TimeValue.inc (limited to 'llvm/lib/Support/Unix') diff --git a/llvm/lib/Support/Unix/TimeValue.inc b/llvm/lib/Support/Unix/TimeValue.inc new file mode 100644 index 00000000000..042e0dacc34 --- /dev/null +++ b/llvm/lib/Support/Unix/TimeValue.inc @@ -0,0 +1,54 @@ +//===- Unix/TimeValue.cpp - Unix TimeValue Implementation -------*- C++ -*-===// +// +// The LLVM Compiler Infrastructure +// +// This file is distributed under the University of Illinois Open Source +// License.
