Cthulhu.jl is a powerful introspection tool for exploring the Julia compiler’s method dispatch and type inference system. It allows users to interactively descend into the type-inferred lowered and LLVM IR of Julia functions from the REPL. This makes it ideal for developers who want to optimize performance, debug type instability, or understand how Julia compiles code. Named after the Lovecraftian idea of descending into madness, Cthulhu reveals the "underworld" of Julia compilation.

Features

  • Interactive exploration of type inference and lowered code
  • Displays LLVM IR and native assembly output
  • Allows recursive descent into nested function calls
  • Highlights type instabilities for optimization
  • Integrated with Julia’s REPL for quick access
  • Useful for compiler-level debugging and performance tuning
