The diagnostics I'm missing come from
https://github.com/rust-lang/rust/blob/913350ecaf6a0fc621c6c43f0764956e1c47cc15/compiler/rustc_codegen_gcc/src/context.rs#L478-L484

I saw something similar in rustc_codegen_llvm but #101005 has not finished yet.

I also found some calls to span_invalid_monomorphization_error() that I suspect need to be changed.

https://github.com/rust-lang/rust/blob/913350ecaf6a0fc621c6c43f0764956e1c47cc15/compiler/rustc_codegen_gcc/src/intrinsic/simd.rs#L27-L30

These were not caught by #![deny(...)] and I'm not sure if that means they don't need to be translated, or if this is an edge case.

I feel like LayoutError could basically implement SessionDiagnostic, maybe we could implement it for Spanned<LayoutError> (Spanned)?

These should be translated, and ideally the lint would fire on them, I've added a link to this to #100717 so someone can go fix that.

This is a great start, thanks!

This is great progress, I'd like it if you could address the feedback from my earlier comment (#101075 (comment)) :)

I tried to implement SessionDiagnostic for LayoutError and Spanned<T>, but I ended up getting lifetime errors. I don't quite understand it, but I think it was related to 'gcc and tcx being different lifetimes.

I also found some calls to span_invalid_monomorphization_error() that I suspect need to be changed.

I'm still working on this. I think I need to create a new function similar to span_invalid_monomorphization_error() that takes a SessionDiagnostic. I also realized there are lots of other untranslatable strings in simd.rs that I would need to fix.

If you share the code from your attempt then maybe we can work this out.

davidtwco · 2022-09-22T13:50:25Z

Apologies for the delay in responding to this, replied to the pending comments now.

ellishg · 2022-09-24T18:44:19Z

I've finally figured out the lifetime error. Thanks @davidtwco for all your help! I believe I've migrated all the diagnostics so this is ready for review!
