That’s a 3300 line cpp file, care to cite a specific example?

The entire file contains WarpBuilder, which is behind the JIT speedup that this thread is about.

The whole component was the cool stuff I was referring too. I linked it mainly to show that it's C++ instead of, say, Rust, not to highlight any component of it.

I was thinking new stuff was done in Rust. I guess Gecko is CPP only?

I think some Rust components have been written and integrated into Firefox. But the core Firefox codebase - including Gecko - is still C++ so it's not easy use Rust there.

On a related note, Chrome is looking at integrating Rust into its C++ codebase.

Not true majority by far is done in c++. Easily confirmed by downloading the browser source and using a LOC analyzer to see how much code is done in which languages

Yeah, not interested enough to do that.

Please cite a line or maybe a git comment. No-one is going to filter through 3000 lines of cpp code.
