Whistler Compiles eBPF Programs Directly From Lisp
8.1
Whistler 1.0 is a Common Lisp-based compiler and loader that generates optimized eBPF bytecode at macroexpansion, producing ELF eBPF files without clang/LLVM. It embeds bytecode as literals, supports REPL-based compile/load/unload workflows, and provides cross-language struct generation for C, Go, Rust, and Python. The tool includes a pure-Common-Lisp loader and enables non-root usage via Linux capabilities.
Key Points
- 1Compiles Common Lisp DSL into optimized eBPF bytecode at macroexpansion, embedding byte arrays in expansions
- 2Eliminates clang and LLVM toolchain, produces ELF files, and provides compile-time verifier errors with context
- 3Enables single-process REPL development, runtime loading/unloading, and cross-language struct generation for polyglot userspace
Scoring Rationale
High novelty and direct usability for eBPF workflows, but niche systems focus limits broad AI/ML relevance.
