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. --- .../Target/WebAssembly/WebAssemblySubtarget.cpp | 59 ---------------------- 1 file changed, 59 deletions(-) delete mode 100644 contrib/llvm/lib/Target/WebAssembly/WebAssemblySubtarget.cpp (limited to 'contrib/llvm/lib/Target/WebAssembly/WebAssemblySubtarget.cpp') diff --git a/contrib/llvm/lib/Target/WebAssembly/WebAssemblySubtarget.cpp b/contrib/llvm/lib/Target/WebAssembly/WebAssemblySubtarget.cpp deleted file mode 100644 index 196a74565285..000000000000 --- a/contrib/llvm/lib/Target/WebAssembly/WebAssemblySubtarget.cpp +++ /dev/null @@ -1,59 +0,0 @@ -//===-- WebAssemblySubtarget.cpp - WebAssembly Subtarget Information ------===// -// -// 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 -// -//===----------------------------------------------------------------------===// -/// -/// \file -/// This file implements the WebAssembly-specific subclass of -/// TargetSubtarget. -/// -//===----------------------------------------------------------------------===// - -#include "WebAssemblySubtarget.h" -#include "MCTargetDesc/WebAssemblyMCTargetDesc.h" -#include "WebAssemblyInstrInfo.h" -#include "llvm/Support/TargetRegistry.h" -using namespace llvm; - -#define DEBUG_TYPE "wasm-subtarget" - -#define GET_SUBTARGETINFO_CTOR -#define GET_SUBTARGETINFO_TARGET_DESC -#include "WebAssemblyGenSubtargetInfo.inc" - -WebAssemblySubtarget & -WebAssemblySubtarget::initializeSubtargetDependencies(StringRef FS) { - // Determine default and user-specified characteristics - - if (CPUString.empty()) - CPUString = "generic"; - - ParseSubtargetFeatures(CPUString, FS); - return *this; -} - -WebAssemblySubtarget::WebAssemblySubtarget(const Triple &TT, - const std::string &CPU, - const std::string &FS, - const TargetMachine &TM) - : WebAssemblyGenSubtargetInfo(TT, CPU, FS), CPUString(CPU), - TargetTriple(TT), FrameLowering(), - InstrInfo(initializeSubtargetDependencies(FS)), TSInfo(), - TLInfo(TM, *this) {} - -bool WebAssemblySubtarget::enableAtomicExpand() const { - // If atomics are disabled, atomic ops are lowered instead of expanded - return hasAtomics(); -} - -bool WebAssemblySubtarget::enableMachineScheduler() const { - // Disable the MachineScheduler for now.
