• Memory Safety for the World’s Largest Software Project

• Adding a Rust compiler front end to GCC
  7 projects | news.ycombinator.com | 17 Jun 2022

  Because there is often some confusion, note that there are two different projects in this space with different approaches.

  The project discussed in the video above is a new front end to GCC (written in C++, as is typical for GCC frontends) and is developed here: https://github.com/Rust-GCC/gccrs

  The other project involves plugging GCC's backend into the existing rustc frontend, and is developed here: https://github.com/rust-lang/rustc_codegen_gcc

  Both projects intend to eventually allow Rust code to make use of GCC. But they will likely appeal to different sets of users: the former project appeals to people invested in the GCC ecosystem who want to use Rust without installing a whole separate toolchain, and the latter to people invested in the Rust ecosystem who want to benefit from GCC's broader target support.

• Things Are Getting Rusty In Kernel Land (Hackaday)

  My understanding was the current preference was going to be rust_codegen_gcc which still uses the rustc front end, and leverages gcc's backend via libgccjit. Though to be clear the Linux-Rust people were "either will probably work for us on that long term thing, we will let them evolve before we decide on which" and "for now neither is close to ready enough, so we will require rustc/llvm stuff for a while yet".

  Arm support is great as it's a Tier 1 target. But for languages that aren't Tier 1 or 2, you're probably SOL for now. Currently Rust's main codegen is LLVM based so you are mostly limited to architectures it support, until things like rust_codegen_gcc are ready for production.

  Another feature that is different between GCC and Clang is the handling of NaN, but this issue is easier to handle in the front-end.

• Can Rust do every low level stuff C/C++ do?

  There is also https://github.com/rust-lang/rustc_codegen_gcc which uses GCC JIT to compile Rust and maybe support all the archs GCC can.

• How fast is Python - MicroPython versus C++

  There is a GCC backend for Rust that is in progress which will bridge that gap.

  That said, having Rust support for every Linux target would absolutely help, insofar as that would allow using Rust in the core kernel or architecture-independent code such as filesystems or portable drivers. rustc_codegen_gcc is making great progress on that front. (See https://github.com/sponsors/antoyo to support that work.) I'm hoping we can get to the point soon where you can install it via rustup, and get to the point soon after that where it can get automatically pulled in if you rustup target add some target that uses it.

• Why doesn’t rustc eliminate this empty loop?

• A C perspective - Why should I want Rust to succeed?
  7 projects | reddit.com/r/rust | 18 Jan 2022

  Another point is that you may want to compile the C code with clang, so that you will compare both with the same backend. (there's an experimental GCC backend for the Rust compiler but it isn't usable yet)

• Is there any other language that has something crucial that Rust hasn't? Minus libraries.
  5 projects | reddit.com/r/rust | 30 Dec 2021

  I’m not sure I understand what you mean. There are at least two active projects to enable compilation via GCC (gccrs & rustc_codegen_gcc). As I mentioned, there isn’t anything about the language itself that ties it to LLVM, nor precludes use of other compilers and/or supporting additional architectures.

• GCC Rust in 2021

  While the project is not in direct competition with the official Rust compiler paired the LLVM backend, there is also a GCC backend for the official Rust compiler, called rustc_codegen_gcc.

  The one on the bottom left is mrustc, a compiler which is specifically designed to bootstrap the actual rustc with minimal optimization; it is not general-purpose. The one on the bottom right is rustc_codegen_gcc, an experimental backend that allows rustc to use GCC instead of LLVM; it is nowhere near ready for production right now. The only relevant compilers here are rustc and gccrs, the latter of which is also nowhere near ready for production.
