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/TextAPI/ELF/TBEHandler.cpp | 160 ---------------------------- 1 file changed, 160 deletions(-) delete mode 100644 contrib/llvm/lib/TextAPI/ELF/TBEHandler.cpp (limited to 'contrib/llvm/lib/TextAPI/ELF/TBEHandler.cpp') diff --git a/contrib/llvm/lib/TextAPI/ELF/TBEHandler.cpp b/contrib/llvm/lib/TextAPI/ELF/TBEHandler.cpp deleted file mode 100644 index cb597d8896e8..000000000000 --- a/contrib/llvm/lib/TextAPI/ELF/TBEHandler.cpp +++ /dev/null @@ -1,160 +0,0 @@ -//===- TBEHandler.cpp -----------------------------------------------------===// -// -// 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 -// -//===-----------------------------------------------------------------------===/ - -#include "llvm/TextAPI/ELF/TBEHandler.h" -#include "llvm/ADT/StringSwitch.h" -#include "llvm/ADT/StringRef.h" -#include "llvm/Support/Error.h" -#include "llvm/Support/YAMLTraits.h" -#include "llvm/TextAPI/ELF/ELFStub.h" - -using namespace llvm;
