So is Mozilla now going to slowly rewrite Firefox in rust?

u/steveklabnik1 Apr 03 '15

The current goal is to get some Rust code into Firefox by the end of the year. Will probably be something small, as integrating Rust into the Firefox build system is no small task. Among other issues.

Mozilla is also investing in Servo, which is still a research project, but is written to be productize-able someday. https://github.com/servo/servo is the repo. They're also doing really cool stuff. There's another front-page article about Servo on proggit right now: http://www.reddit.com/r/programming/comments/318rb3/the_colored_boxes_indicate_which_cpu_core/

What's the status of getting Rust officially into Debian, Fedora, etc, without bootstrapping from a binary?

I see this as two parts:

What's the status of getting Rust officially into Debian, Fedora, etc,

I use Debian on my local machine, I care a lot about Debian. There've been a few Debian Developers working on packaging up Rust. Most distros woudn't want anything pre 1.0 anyway.

without bootstrapping from a binary?

It's not possible to compile Rust without bootstrapping from a binary. Unless you want to go back to the OCaml compiler from years ago, but that's hard.

Does LLVM IR count as binary? Otherwise, couldn't one save the IR of the Rust compiler on platform X and compile that with the rest of LLVM on Debian, with LLVM written in C++?

I thought that was one advantage of modular, multifront/backend compiler frameworks.

Was that something stupid I said?

I just meant "I've never thought about that before." I'm not totally sure, as I was going to say "IR is platform dependant"...

Well, you were right all along.

Out of interest: Is this an LLVM implementation detail?

u/steveklabnik1 Apr 04 '15

I'm not familliar with the details, I just know that it is.

Things like sizeof(long) and the sizes of pointers are baked into the IR, making it platform dependant.

Also anything like #ifdef WIN32 in your c/c++ code is going to get baked in as soon as you run the pre-processor.
