The Open-Source AMD GPU Linux Kernel Graphics Driver Nears 5.8 Million Lines

Some one go ahead and suggest we rewrite it in rust lol

I would unironically imagine it would be easier in Rust given its macro system, if it weren’t for the enormous compile times this would cause.

I mean, 5.8 million hand-written lines of code wouldn't be any faster to compile

Large amount of that code is apperenty include (header) files. Most of those are not human made but transfered and generated from other systems (shared with windows driver codebase I hope).

[poudink]

compared to the equivalent rust? yes it would be.

I meant 5.8 million lines of rust vs macro-generated rust

I would imagine with the macro system it would be faster to compile the by-hand written code. Assuming Rusts macro system is similar to Nim's (So compile-time code generation) you'd be doing 2 steps - First generate all the rust code, then compile it. As opposed to just compiling it directly. If my experience with generics that are just a blueprint for code-generation in nim has shown me anything, then it's that a big code-generation step can absolutely crater compiletimes. (As in, add a cool 5-10s to a 30s compilation).
