Traces already contain module info without that.
It's easy to forget to call `finalize_*` on a module.
In particular, macros enum and trait modules weren't finalized.
By happy accident macros weren't placed into those modules until now.
Test HRTB issue accepted by compiler
Hi! First Rust PR, so if anything needs changing just let me know and I'll take care of it right away.
Closes#50301 which was marked E-needstest
Tweak mismatched types error
- Change expected/found for type mismatches in `break`
- Be more accurate when talking about diverging match arms
- Tweak wording of function without a return value
- Suggest calling bare functions when their return value can be coerced to the expected type
- Give more parsing errors when encountering `foo(_, _, _)`
Fix#51767, fix#62677, fix#63136, cc #37384, cc #35241, cc #51669.
Don't recommend `extern crate` syntax
`extern crate` syntax is not a good recommendation any more, so I've changed it to just print a suggested crate name.
Revert "Rollup merge of #62696 - chocol4te:fix_#62194, r=estebank"
This reverts commit df21a6f040 (#62696), reversing
changes made to cc16d04869.
That PR makes error messages worse than before, and we couldn't come up with a way of actually making them better, so revert it for now. Any idea for making this error message better is welcome!
Fixes#63145.

Make use of possibly uninitialized data [E0381] a hard error
This is one of the behaviors we no longer allow in NLL. Since it can
lead to undefined behavior, I think it's definitely worth making it a
hard error without waiting to turn off migration mode (#58781).
Closes#60450.
My ulterior motive here is making it impossible to leave variables
partially initialized across a yield (see #60889, discussion at #63035), so
tests are included for that.
cc #54987

I'm not sure if bypassing the buffer is a good way of doing this. We could also make a `force_errors_buffer` or similar that gets recombined with all the errors as they are emitted. But this is simpler and seems fine to me.

Miri: dispatch first on the type
Based on the fact that Miri now always has intptrcast available, we can change binops and casts to first check the type of the source operand and then decide based on that what to do, instead of considering the value (pointer vs bits) first.
Change opaque type syntax from `existential type` to type alias `impl Trait`
This implements a new feature gate `type_alias_impl_trait` (this is slightly different from the originally proposed feature name, but matches what has been used in discussion since), deprecating the old `existential_types` feature.
The syntax for opaque types has been changed. In addition, the "existential" terminology has been replaced with "opaque", as per previous discussion and the RFC.
This makes partial progress towards implementing https://github.com/rust-lang/rust/issues/63063.
