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. --- .../llvm/lib/DebugInfo/PDB/Native/SymbolStream.cpp | 45 ++++++++++++++++++++++ 1 file changed, 45 insertions(+) create mode 100644 contrib/llvm-project/llvm/lib/DebugInfo/PDB/Native/SymbolStream.cpp (limited to 'contrib/llvm-project/llvm/lib/DebugInfo/PDB/Native/SymbolStream.cpp') diff --git a/contrib/llvm-project/llvm/lib/DebugInfo/PDB/Native/SymbolStream.cpp b/contrib/llvm-project/llvm/lib/DebugInfo/PDB/Native/SymbolStream.cpp new file mode 100644 index 000000000000..003840b6e67e --- /dev/null +++ b/contrib/llvm-project/llvm/lib/DebugInfo/PDB/Native/SymbolStream.cpp @@ -0,0 +1,45 @@ +//===- SymbolStream.cpp - PDB Symbol Stream Access ------------------------===// +// +// 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/DebugInfo/PDB/Native/SymbolStream.h" + +#include "llvm/DebugInfo/CodeView/CodeView.h" +#include "llvm/DebugInfo/CodeView/SymbolRecord.h" +#include "llvm/DebugInfo/MSF/MappedBlockStream.h" +#include "llvm/Support/BinaryStreamReader.h" +#include "llvm/Support/Endian.h" + +using namespace llvm; +using namespace llvm::msf; +using namespace llvm::support; +using namespace llvm::pdb; + +SymbolStream::SymbolStream(std::unique_ptr Stream) + : Stream(std::move(Stream)) {} + +SymbolStream::~SymbolStream() {} + +Error SymbolStream::reload() { + BinaryStreamReader Reader(*Stream); + + if (auto EC = Reader.readArray(SymbolRecords, Stream->getLength())) + return EC; + + return Error::success(); +} + +iterator_range +SymbolStream::getSymbols(bool *HadError) const { + return llvm::make_range(SymbolRecords.begin(HadError), SymbolRecords.end()); +} + +Error SymbolStream::commit() { return Error::success(); } + +codeview::CVSymbol SymbolStream::readRecord(uint32_t Offset) const { + return *SymbolRecords.at(Offset); +} -- cgit v1.2.3
