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. --- .../Plugins/Language/CPlusPlus/LibCxxQueue.cpp | 60 ++++++++++++++++++++++ 1 file changed, 60 insertions(+) create mode 100644 contrib/llvm-project/lldb/source/Plugins/Language/CPlusPlus/LibCxxQueue.cpp (limited to 'contrib/llvm-project/lldb/source/Plugins/Language/CPlusPlus/LibCxxQueue.cpp') diff --git a/contrib/llvm-project/lldb/source/Plugins/Language/CPlusPlus/LibCxxQueue.cpp b/contrib/llvm-project/lldb/source/Plugins/Language/CPlusPlus/LibCxxQueue.cpp new file mode 100644 index 000000000000..4b72089c6ba2 --- /dev/null +++ b/contrib/llvm-project/lldb/source/Plugins/Language/CPlusPlus/LibCxxQueue.cpp @@ -0,0 +1,60 @@ +//===-- LibCxxQueue.cpp -----------------------------------------*- C++ -*-===// +// +// 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 "LibCxx.h" +#include "lldb/DataFormatters/FormattersHelpers.h" + +using namespace lldb; +using namespace lldb_private; + +namespace { + +class QueueFrontEnd : public SyntheticChildrenFrontEnd { +public: + QueueFrontEnd(ValueObject &valobj) : SyntheticChildrenFrontEnd(valobj) { + Update(); + } + + size_t GetIndexOfChildWithName(ConstString name) override { + return m_container_sp ? m_container_sp->GetIndexOfChildWithName(name) + : UINT32_MAX; + } + + bool MightHaveChildren() override { return true; } + bool Update() override; + + size_t CalculateNumChildren() override { + return m_container_sp ? m_container_sp->GetNumChildren() : 0; + } + + ValueObjectSP GetChildAtIndex(size_t idx) override { + return m_container_sp ? m_container_sp->GetChildAtIndex(idx, true) + : nullptr; + } + +private: + ValueObjectSP m_container_sp; +}; +} // namespace + +bool QueueFrontEnd::Update() { + m_container_sp.reset(); + ValueObjectSP c_sp = m_backend.GetChildMemberWithName(ConstString("c"), true); + if (!c_sp) + return false; + m_container_sp = c_sp->GetSyntheticValue(); + return false; +} + +SyntheticChildrenFrontEnd * +formatters::LibcxxQueueFrontEndCreator(CXXSyntheticChildren *, + lldb::ValueObjectSP valobj_sp) { + if (valobj_sp) + return new QueueFrontEnd(*valobj_sp); + return nullptr; +} -- cgit v1.2.3
