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. --- .../DebugInfo/PDB/Native/InjectedSourceStream.cpp | 65 ++++++++++++++++++++++ 1 file changed, 65 insertions(+) create mode 100644 contrib/llvm-project/llvm/lib/DebugInfo/PDB/Native/InjectedSourceStream.cpp (limited to 'contrib/llvm-project/llvm/lib/DebugInfo/PDB/Native/InjectedSourceStream.cpp') diff --git a/contrib/llvm-project/llvm/lib/DebugInfo/PDB/Native/InjectedSourceStream.cpp b/contrib/llvm-project/llvm/lib/DebugInfo/PDB/Native/InjectedSourceStream.cpp new file mode 100644 index 000000000000..3f4101db7b93 --- /dev/null +++ b/contrib/llvm-project/llvm/lib/DebugInfo/PDB/Native/InjectedSourceStream.cpp @@ -0,0 +1,65 @@ +//===- InjectedSourceStream.cpp - PDB Headerblock 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/InjectedSourceStream.h" + +#include "llvm/DebugInfo/MSF/MappedBlockStream.h" +#include "llvm/DebugInfo/PDB/Native/Hash.h" +#include "llvm/DebugInfo/PDB/Native/PDBStringTable.h" +#include "llvm/DebugInfo/PDB/Native/RawConstants.h" +#include "llvm/DebugInfo/PDB/Native/RawTypes.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; + +InjectedSourceStream::InjectedSourceStream( + std::unique_ptr Stream) + : Stream(std::move(Stream)) {} + +Error InjectedSourceStream::reload(const PDBStringTable &Strings) { + BinaryStreamReader Reader(*Stream); + + if (auto EC = Reader.readObject(Header)) + return EC; + + if (Header->Version != + static_cast(PdbRaw_SrcHeaderBlockVer::SrcVerOne)) + return make_error(raw_error_code::corrupt_file, + "Invalid headerblock header version"); + + if (auto EC = InjectedSourceTable.load(Reader)) + return EC; + + for (const auto& Entry : *this) { + if (Entry.second.Size != sizeof(SrcHeaderBlockEntry)) + return make_error(raw_error_code::corrupt_file, + "Invalid headerbock entry size"); + if (Entry.second.Version != + static_cast(PdbRaw_SrcHeaderBlockVer::SrcVerOne)) + return make_error(raw_error_code::corrupt_file, + "Invalid headerbock entry version"); + + // Check that all name references are valid. + auto Name = Strings.getStringForID(Entry.second.FileNI); + if (!Name) + return Name.takeError(); + auto ObjName = Strings.getStringForID(Entry.second.ObjNI); + if (!ObjName) + return ObjName.takeError(); + auto VName = Strings.getStringForID(Entry.second.VFileNI); + if (!VName) + return VName.takeError(); + } + + assert(Reader.bytesRemaining() == 0); + return Error::success(); +} -- cgit v1.2.3
