I think that was the exact opposite - they generated an interpreter from their JIT. This generates a JIT from their interpreter, like PyPy and Truffle do.

It seems to be to generate JIT snippets from the Rust compiler, not an interpreter.

As I understand it you write an interpreter in Rust then you generate a JIT compiler from that interpreter.

First thought was: "Is this another Terry Davis language/framework?"[1] No, no it is not. I would suggest changing the name from HolyJit to anything else. [1] https://en.m.wikipedia.org/wiki/TempleOS

I am absolutely convinced that the god of Terry A. Davis. does not approve of JIT compilation.

Can we just drop the JS VM and embed some nicer VM (JVM, DartVM) instead?

I agree this would be better, but backward compatibility constraint makes it impossible. WebAssembly is an attempt to add a nicer VM in addition to JS VM.

Why does the Cargo.toml[1] file in the source repo for HolyJit have the word "brainfuck"[2] in it?

Does that have some significance to Rust or Mozilla? Or is this a case of copy pasta?

Yes, once you convince everyone to drop the thing we have that works and implement the thing we don't have that doesn't work. In short: you complain as though it were an easy change to make.

Checking other comments, it seems like this account has been hacked and used to post offensive comments.

Then the original owner should send an email to hn@ycombinator.com to get it back.

I guess the mods know about it already now and have removed the offending comments. The profile page could also do with some scrubbing however.

I'm not sure as to what is fundamentally different about this JIT-compiler (except for the awesome name of course) Is it basically just a Rust rewrite which also tries to reduce the complexity of their current just-in-time compiler? Edit: By calling it "just" a Rust rewrite, I'm not implying that's a simple undertaking, even moreso considering the complexity of modern JS engines.

Name reminds me of TempleOs's HolyC language...

Me too.

I wonder why they don't mention it.

I haven't looked closely at the architecture, but isn't JIT compilation pretty much how Holy C works?

The HolyJit repo has a brainfuck jit example in the repository: https://github.com/nbp/holyjit/blob/master/examples/brainfuc...
