Previously, the compiler didn't suggest similarly named associated items unlike we do in many situations. This patch adds such diagnostics for associated functions, types and constants.
In function arguments and let bindings, do not suggest changing `C` to `Foo::C` unless `C` is the only variant of `Foo`, because it won't work. The general warning is still kept, because code like this is confusing. Fixes rust-lang#88730
Downloading LLVM from CI works for all platforms now.
Fix ICE when `start` lang item has wrong generics In my previous pr rust-lang#87875 I missed the requirements on the `start` lang item due to its relative difficulty to test and opting for more conservative estimates. This fixes that by updating the requirement to be exactly one generic type. The `start` lang item should have exactly one generic type for the return type of the `main` fn ptr passed to it. I believe having zero would previously *sometimes* compile (often with the use of `fn() -> ()` as the fn ptr but it was likely UB to call if the return type of `main` was not `()` as far as I know) however it also sometimes would not for various errors including ICEs and LLVM errors depending on exact situations. Having more than 1 generic has always failed with an ICE because only the one generic type is expected and provided. Fixes rust-lang#79559, fixes rust-lang#73584, fixes rust-lang#83117 (all duplicates) Relevant to rust-lang#9307 r? ````@cjgillot````

…-assoc-items, r=estebank Suggest similarly named associated items in trait impls Fix rust-lang#85942 Previously, the compiler didn't suggest similarly named associated items unlike we do in many situations. This patch adds such diagnostics for associated functions, types, and constants.
Add `#[must_not_suspend]` to some types in std I am not sure what else should have it? `Ref`?

…ariant-match, r=davidtwco fix(lint): don't suggest refutable patterns to "fix" irrefutable bind In function arguments and let bindings, do not suggest changing `C` to `Foo::C` unless `C` is the only variant of `Foo`, because it won't work. The general warning is still kept, because code like this is confusing. Fixes rust-lang#88730 p.s. `src/test/ui/lint/lint-uppercase-variables.rs` already tests the one-variant case.
…li-obk CTFE: tweak aggregate rvalue handling I have not looked at this code in ages... I think Miri does not even hit it, since (most?) aggregate rvalues are lowered somewhere in the MIR pipeline, but CTFE does hit it. So this adds some extra sanity assertions, and removes a ZST special case -- ZST should only be special cased fairly late (when the actual memory access happens); e.g. `!` is a ZST and we still want `copy_op` to be called for it since it will perform validation (and raise UB, since `!` is never valid).
bootstrap: Update comment in config.library.toml. Downloading LLVM from CI works for all platforms now. All other templates in this directory already have the proper comment. Seems this one was neglected.
