Why It Matters

For a platform engineer debugging large-scale native applications on Windows, this open-source toolchain offers a faster linker and a custom debug info format that could significantly reduce compile-debug cycle times and eliminate PDB size limitations.

Key Takeaways

Evaluate the RAD Linker for your CI/CD pipeline if you build large Windows executables, as it promises 50% faster links and avoids PDB overflow.

A native, user-mode, multi-process, graphical debugger. - EpicGames/raddebugger

Summary

Epic Games open-sourced RAD Debugger, a native user-mode multi-process graphical debugger currently supporting local Windows x64 debugging with PDBs, with plans for Linux and DWARF support. It introduces two companion technologies: the RAD Debug Info (RDI) format, a custom debug info format converted from PDB/DWARF on-demand, and the RAD Linker, a high-performance x64 PE/COFF linker that achieves 50% faster link times on huge executables by using multi-threading and optional large memory pages. The linker is MSVC-compatible and designed to avoid PDB overflow issues in massive projects.
