🤔 Ah, the riveting saga of the #GDB #JIT interface, where we discover that #debugging JIT-compiled code is as clear as mud without #DWARF sprinkles. 🐢 Because who wouldn't want to step through machine code one agonizing instruction at a time while GDB plays the clueless sidekick? 🤷‍♂️🔧

The GDB JIT interface

GDB is great for stepping through machine code to figure out what is going on. It uses debug information under the hood to present you with a tidy backtrace and also determine how much machine code to print when you type disassemble.

Exploring Speculative JIT Compilation for Emacs Lisp with Java

This Org-mode file was used for an org-present presentation at EmacsConf 2025 – Juicemacs. This blog post is adapted from that presentation, with added transcript and explanations for a bunch of things I didn't dig into during the presentation.

How Ruby Executes JIT Code: The Hidden Mechanics Behind the Magic

Where does JIT-compiled code live? How does Ruby switch between bytecode and native execution? Why does TracePoint slow everything down? This post answers the JIT questions most Ruby developers have but rarely see explained.

PEP 744 – JIT Compilation | peps.python.org

Earlier this year, an experimental “just-in-time” compiler was merged into CPython’s main development branch. While recent CPython releases have included other substantial internal changes, this addition represents a particularly significant departure f...
