omg I've been chasing a good GDB/LLDB MCP server for a while and it turns out LLDB v21+ has it built-in!!

okay well, my profiler only works if you run it inside of lldb
I guess lldb is a dependency now.

writing rust is a lot more exciting* since I brought cranelift (a JIT compiler) into the mix
*spending a lot more time in lldb, valgrind, etc.

achievement unlocked: making a thing that generates executable code that LLDB can step through with full debuginfo so I can see my IR directly in the debugger

friend of mine is now referring to lldb exclusively as laladubu in VC and I feel a bit guilty for unleashing this upon my friend group

Great language support means nothing without great tooling. Watch Jonas Devlieghere show how LLDB brings first-class debugging to Swift on WebAssembly. fosdem.org/2026/schedul... #Wasm #FOSDEM

Added some new commands to the GDB & LLDB plugin for V8..
`v8 source`: shows the JS source of the selected frame
`v8 isolate`: find the isolate address in the current thread, works from the coredump too (implementing that in LLDB was quite a bit of challenge!)

oh mine's working (using lib.rs/crates/lldb — the SB interface) I'm just wondering if it's novel or if it's been done before
lldb
Rust-like bindings to the public LLDB API. LLDB is the debugger from the LLVM project and is the system debugger on macOS.

hey is there any compiler out there that has tooling that steps through CFG-MIR in an interpreter AND machine code in LLDB in lockstep automatically to find where they diverge?

I wrote about some Rust debuginfo tooling I've been working on recently:
Introducing Rudy: A Toolchain for Rust Debuginfo
Rudy provides libraries for working with Rust's DWARF debuginfo and an lldb extension built on top of them.

I'm not even joking when I say Claude Code wrote over 50 lines of code while Xcode's debugger was hanging here waiting for my lldb command to resolve.

you can try lldb, which should be good enough for gdb usecases.

Moving along with the debug_helper-based LLDB & GDB V8 plugins...this now supports basic object inspection! It was fun to write tests that deliberately corrupt the memory and make sure the plugin falls back gracefully, something I've never tried before when maintaining other plugins :D

I think, as a JavaScript developer, when you need to reach for LLDB, you've gone to deep.

One of the many joys of using AI for programming is the creation of huge PRs on complex topics that the authors barely understand, but still suggest "because they work". Here's a great example from #OCaml github.com/ocaml/ocaml/...
