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. --- .../WebAssembly/WebAssemblyDebugValueManager.cpp | 45 ++++++++++++++++++++++ 1 file changed, 45 insertions(+) create mode 100644 contrib/llvm-project/llvm/lib/Target/WebAssembly/WebAssemblyDebugValueManager.cpp (limited to 'contrib/llvm-project/llvm/lib/Target/WebAssembly/WebAssemblyDebugValueManager.cpp') diff --git a/contrib/llvm-project/llvm/lib/Target/WebAssembly/WebAssemblyDebugValueManager.cpp b/contrib/llvm-project/llvm/lib/Target/WebAssembly/WebAssemblyDebugValueManager.cpp new file mode 100644 index 000000000000..579377c9a5d7 --- /dev/null +++ b/contrib/llvm-project/llvm/lib/Target/WebAssembly/WebAssemblyDebugValueManager.cpp @@ -0,0 +1,45 @@ +//===-- WebAssemblyDebugValueManager.cpp - WebAssembly DebugValue Manager -===// +// +// 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 manager for MachineInstr DebugValues. +/// +//===----------------------------------------------------------------------===// + +#include "WebAssemblyDebugValueManager.h" +#include "WebAssemblyMachineFunctionInfo.h" +#include "llvm/CodeGen/MachineInstr.h" + +using namespace llvm; + +WebAssemblyDebugValueManager::WebAssemblyDebugValueManager( + MachineInstr *Instr) { + Instr->collectDebugValues(DbgValues); +} + +void WebAssemblyDebugValueManager::move(MachineInstr *Insert) { + MachineBasicBlock *MBB = Insert->getParent(); + for (MachineInstr *DBI : reverse(DbgValues)) + MBB->splice(Insert, DBI->getParent(), DBI); +} + +void WebAssemblyDebugValueManager::updateReg(unsigned Reg) { + for (auto *DBI : DbgValues) + DBI->getOperand(0).setReg(Reg); +} + +void WebAssemblyDebugValueManager::clone(MachineInstr *Insert, + unsigned NewReg) { + MachineBasicBlock *MBB = Insert->getParent(); + MachineFunction *MF = MBB->getParent(); + for (MachineInstr *DBI : reverse(DbgValues)) { + MachineInstr *Clone = MF->CloneMachineInstr(DBI); + Clone->getOperand(0).setReg(NewReg); + MBB->insert(Insert, Clone); + } +} -- cgit v1.2.3
