I learned it combining the Book and Rustlings. There's a table in the exercises directory mapping the exercises to the chapters of the book, so I'd every day do the exercises for yesterdays chapter first before todays chapter to have some sort of spaced repetition. For more material, check out https://github.com/jondot/rust-how-do-i-start

You can try https://github.com/jondot/rust-how-do-i-start which contains things to try out that I've curated. Cross off things that don't work, and feel free to reach out if none of it work for you.

I highly recommend taking a look at this github repo, it has many projects and resources to help you!

Rustlings is great. I did them after a couple of years in Rust for the same reason, and it was definitely worth it. You might want to check out https://github.com/jondot/rust-how-do-i-start as well where I put all these kind of things that I could find.

If you aren't a complete beginner, then this github repo is VERY useful

This is mine but also incorporates things I wish I had when I started, and also recommendation from other people as well. https://github.com/jondot/rust-how-do-i-start

Alternatively, there's another initiative called codegen_gcc which is about using GCC as a backend for the rustc compiler. It's (much) more advanced in Rust support, but I am not sure how easy it would be to use a modified libgccjit from there.

In addition to what others have said about platform support, Rust is also on its way to gaining more platform support through rustc_codegen_gcc, the GCC codegen backend for rustc, as an alternative to the LLVM backend. That means many of the platforms GCC supports will suddenly become available with Rust.

Yeah, rustc_codegen_gcc is a GCC backend for rustc, and its making a lot of good regular progress.

gcc-rs is one of two projects for bringing Rust to gcc. gcc-rs is the more ambitious of the two, with an entirely new frontend. There is also rustc_codegen_gcc (https://github.com/rust-lang/rustc_codegen_gcc) that keeps the rustc frontend, and only swaps out LLVM for GCC at the codegen stage.

Fixing unwinding in release mode is still ungoing. I could use some help here, so anyone with some understanding of unwinding, landing pads or GCC, please come on this issue to discuss this.

Additionally, there is gcc codegen for rustc (https://github.com/rust-lang/rustc_codegen_gcc), which is not a compiler per se, but an alternative code generator, with more architectures supported and other nice things. It's also coming along, but there's still a lot of work to do there too. There's also Cranelift codegen (https://github.com/bjorn3/rustc_codegen_cranelift), which is designed to make debug builds faster, but this is not as exciting/useful as the other 2.

Good idea. I added the tag "help wanted" to the issue.

Also, there are indeed ABI issues, e.g. for 128-bit integers and NaN.

I'm excited about both the backend & the frontend.

There is also a project for rustc to use GCC instead of LLVM for codegen.
