- DWARF v5 debug information support added to OCaml native compiler for source-level debugging in GDB and LLDB.
- Core DWARF support includes function, type, and line number debug info following DWARF 4/5 specifications.
- Platform support covers macOS (Mach-O) and Linux (ELF) with architecture-specific implementations for AMD64 and ARM64.
- Tooling includes LLDB Python extensions for OCaml value pretty-printing and enhanced debugging commands.
- Command-line interface adds -g flag for DWARF generation and options for controlling debug info detail.
- Implementation includes variable tracking through compilation pipeline and proper scope handling for let-bound variables.
- Comprehensive testing verifies debugger functionality including breakpoints, source locations, and variable inspection.
- PR includes 13k lines of code but faced integration challenges due to AI-assisted development approach.
- Discussion highlights tensions between AI-generated contributions and traditional open-source collaboration practices.
