| # DecBench C++ Raw Corpus Archive |
|
|
| > [!NOTE] |
| > This is the **full raw compiled corpus archive** (1,086+ binaries / 8.5 GB). |
| > For the curated, balanced, tri-platform (Linux/Windows/macOS) benchmark evaluation suite, |
| > please see **[sjkim1127/decbench-cpp-dataset-unofficial](https://huggingface.co/datasets/sjkim1127/decbench-cpp-dataset-unofficial)**. |
|
|
|
|
| > **Unofficial.** This is a community-contributed workspace prepared to help the |
| > [DecBench](https://huggingface.co/datasets/noelo-lab/decbench-dataset) maintainers |
| > evaluate multi-language and cross-platform C++ targets. It is **not** an official Noelo-Lab dataset. |
| > It holds target qualification evidence, candidate lists, the scripts that produced them, and a |
| > **cross-platform C++ benchmark corpus** under `cpp-compiled/` containing **1,086+ binaries/debug artifacts |
| > across 43 projects** spanning both **Linux (GCC / DWARF)** and **Windows (native MSVC / CodeView PDB)** |
| > across 3 optimization levels (`O0`, `O2`, `O2-noinline`). |

| | Path | What it holds | |
| |---|---| |
| | `cpp-compiled/` | **Cross-Platform C++ Benchmark Corpus:**<br>• `binaries/<opt>/<project>/` (Linux ELF+DWARF and Windows x64 PE+PDB)<br>• `sources/<project>_sources.tar.gz` (Preprocessed `.ii`/source units)<br>• `manifest.json` (Platform breakdown, SHA256 checksums, byte sizes)<br>• `build_summary.json` (Compilation details & pinned upstream git revisions) | |
| | `docs/curated-sample-set.md` | **Curated Sample-Set Specification:** Balanced ~8–10 project subset across software domains and OSes (Linux + Windows) | |
| | `results/cpp-corpus-2026-09-16/` | Corpus-scale funnel report and the 48-target shortlist (`final-48.csv`) | |
| | `targets/` | Target definitions (TOML) including `targets/windows/` | |

| ## Platform & Domain Coverage (`cpp-compiled/`) |
|
|
| - **Platforms:** |
| - **Linux aarch64:** Built with GCC/G++ 13.3.0 (`-g -fno-builtin -save-temps=obj`). Unstripped ELF with full DWARF. |
| - **Windows x64:** Built with native Visual Studio 2022 MSVC (`cl.exe /Zi /GL-` + `link.exe /DEBUG:FULL /LTCG:OFF`). Windows PE32+ DLLs and EXEs with full matching `.pdb` CodeView symbols. |
| - **Optimization Levels:** |
| - `O0`: Unoptimized (`/Od /Ob0` or `-O0`) |
| - `O2`: Full optimization (`/O2` or `-O2`) |
| - `O2-noinline`: Inlining disabled (`/O2 /Ob0` or `-O2 -fno-inline`) |
| - **Key Real-World Domain Representative Projects:** |
| - **GUI / Physics Simulation:** **The Powder Toy** (C++20, SDL2 rendering, particle simulation, strict *No-AI PR* policy guaranteeing pure human-authored code). |
| - **Low-Level / System Hooking:** **Microsoft Detours** (Win32 machine-code hooking, instruction disasm). |
| - **Network / Updater:** **WinSparkle** (Win32 worker thread pools, asynchronous HTTP). |
| - **System Storage & Compression:** **Google Snappy**, **leveldb**, **mergerfs**. |
| - **CLI / Developer Tool:** **Ninja** (DAG dependency graph evaluation), **wabt**. |
| - **Server / Async Networking:** **Asio**, **Oat++**, **libzmq**. |
| - **Modern C++ Metaprogramming:** **fmt**, **Catch2**, **Microsoft GSL**. |
