# 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`).

## 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**.
