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/CodeView/DebugCrossExSubsection.cpp | 52 ++++++++++++++++++++++ 1 file changed, 52 insertions(+) create mode 100644 contrib/llvm-project/llvm/lib/DebugInfo/CodeView/DebugCrossExSubsection.cpp (limited to 'contrib/llvm-project/llvm/lib/DebugInfo/CodeView/DebugCrossExSubsection.cpp') diff --git a/contrib/llvm-project/llvm/lib/DebugInfo/CodeView/DebugCrossExSubsection.cpp b/contrib/llvm-project/llvm/lib/DebugInfo/CodeView/DebugCrossExSubsection.cpp new file mode 100644 index 000000000000..b23410409f88 --- /dev/null +++ b/contrib/llvm-project/llvm/lib/DebugInfo/CodeView/DebugCrossExSubsection.cpp @@ -0,0 +1,52 @@ +//===- DebugCrossExSubsection.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/DebugInfo/CodeView/DebugCrossExSubsection.h" +#include "llvm/DebugInfo/CodeView/CodeViewError.h" +#include "llvm/Support/BinaryStreamWriter.h" +#include "llvm/Support/Error.h" +#include + +using namespace llvm; +using namespace llvm::codeview; + +Error DebugCrossModuleExportsSubsectionRef::initialize( + BinaryStreamReader Reader) { + if (Reader.bytesRemaining() % sizeof(CrossModuleExport) != 0) + return make_error( + cv_error_code::corrupt_record, + "Cross Scope Exports section is an invalid size!"); + + uint32_t Size = Reader.bytesRemaining() / sizeof(CrossModuleExport); + return Reader.readArray(References, Size); +} + +Error DebugCrossModuleExportsSubsectionRef::initialize(BinaryStreamRef Stream) { + BinaryStreamReader Reader(Stream); + return initialize(Reader); +} + +void DebugCrossModuleExportsSubsection::addMapping(uint32_t Local, + uint32_t Global) { + Mappings[Local] = Global; +} + +uint32_t DebugCrossModuleExportsSubsection::calculateSerializedSize() const { + return Mappings.size() * sizeof(CrossModuleExport); +} + +Error DebugCrossModuleExportsSubsection::commit( + BinaryStreamWriter &Writer) const { + for (const auto &M : Mappings) { + if (auto EC = Writer.writeInteger(M.first)) + return EC; + if (auto EC = Writer.writeInteger(M.second)) + return EC; + } + return Error::success(); +} -- cgit v1.2.3
