2023-09-11Rollup merge of #115708 - RalfJung:homogeneous, r=davidtwcoMatthias Krüger-0/+76
fix homogeneous_aggregate not ignoring some ZST This is an ABI-breaking change, because it fixes bugs in our ABI code. I'm not sure what that means for this PR, we don't really have a process for such changes, do we? I can only hope nobody relied on the old buggy behavior. Fixes https://github.com/rust-lang/rust/issues/115664
2023-09-11Disentangle `Debug` and `Display` for `Ty`.Nicholas Nethercote-5/+5
The `Debug` impl for `Ty` just calls the `Display` impl for `Ty`. This is surprising and annoying. In particular, it means `Debug` doesn't show as much information as `Debug` for `TyKind` does. And `Debug` is used in some user-facing error messages, which seems bad. This commit changes the `Debug` impl for `Ty` to call the `Debug` impl for `TyKind`. It also does a number of follow-up changes to preserve existing output, many of which involve inserting `with_no_trimmed_paths!` calls. It also adds `Display` impls for `UserType` and `Canonical`. Some tests have changes to expected output: - Those that use the `rustc_abi(debug)` attribute. - Those that use the `EMIT_MIR` annotation. In each case the output is slightly uglier than before. This isn't ideal, but it's pretty weird (particularly for the attribute) that the output is using `Debug` in the first place. They're fairly obscure attributes (I hadn't heard of them) so I'm not worried by this. For `async-is-unwindsafe.stderr`, there is one line that now lacks a full path. This is a consistency improvement, because all the other mentions of `Context` in this test lack a path.

2023-07-21Track (partial) niche information in `NaiveLayout`Moulins-2/+2
Still more complexity, but this allows computing exact `NaiveLayout`s for null-optimized enums, and thus allows calls like `transmute::<Option<&T>, &U>()` to work in generic contexts.
