2024-09-17get rid of an old hackLukas Markeffsky-0/+65
For structs that cannot be unsized, the layout algorithm sometimes moves unsized fields to the end of the struct, which circumvented the error for unexpected unsized fields and returned an unsized layout anyway. This commit makes it so that the unexpected unsized error is always returned for structs that cannot be unsized, allowing us to remove an old hack and fixing some old ICE.

Represent `Result<usize, Box<T>>` as ScalarPair(i64, ptr) This allows types like `Result<usize, std::io::Error>` (and integers of differing sign, e.g. `Result<u64, i64>`) to be passed in a pair of registers instead of through memory, like `Result<u64, u64>` or `Result<Box<T>, Box<U>>` are today. Fixes #97540. r? `@ghost`

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.
