DecBench C++ Raw Corpus Archive

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.

Unofficial. This is a community-contributed workspace prepared to help the DecBench 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).

Contents

Path What it holds
cpp-compiled/ Cross-Platform C++ Benchmark Corpus:
• binaries/<opt>/<project>/ (Linux ELF+DWARF and Windows x64 PE+PDB)
• sources/<project>_sources.tar.gz (Preprocessed .ii/source units)
• manifest.json (Platform breakdown, SHA256 checksums, byte sizes)
• 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/
scripts/ Build-probe, multi-opt compilation, and native MSVC qualification scripts

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.
