cranelift

I'm hoping for Cranelift (https://github.com/bytecodealliance/cranelift) to deliver a more JIT-friendly alternative to LLVM (Though it can do AOT compilation too). Another very interesting project, even if it is slightly intimidating in scope, is GraalVM (https://www.graalvm.org).

It's in the works :) https://www.reddit.com/r/rust/comments/enxgwh/cranelift_back... https://github.com/bytecodealliance/cranelift

Depends. Package Management, compiler errors? Absolutely. IDE support? Not so much. I don't think it's fair to compare it to C# / JVM languages, but even compared to other languages, I wouldn't say the tooling is all that great. Macros make IDE support a lot harder than in other languages, the atrocious compile times sure do as well. While IntelliJ Rust and rust-analyzer both try to do their best (kudos to the teams working on them!), it's still nowhere near anything I'd call "stellar". There are mitigations being worked on right now, like compiling macros to WASM[0] and Cranelift[0], but these endeavours, while very promising, I wouldn't call production-ready yet.

Thanks for the answer. Since you are working on debug-specific backend, have you considered Cranelift [1]? In case you never heard of it, it was especially intended for fast codegen (because it's being used to compile WASM in Firefox), and Rust wants to be able to use it for their own debug build. If you were aware of it and decided not to use it, I'd love to know what are your rationals. [1]: https://github.com/bytecodealliance/cranelift
