Emit fewer errors on invalid `#[repr(transparent)]` on `enum`
Fix #68420.
|
|
Implement allow-by-default `multiple_supertrait_upcastable` lint
The lint detects when an object-safe trait has multiple supertraits.
Enabled in libcore and liballoc as they are low-level enough that many embedded programs will use them.

More verbose `Debug` implementation of `std::process:Command`

r=compiler-errors
Always suggest as `MachineApplicable` in `recover_intersection_pat`
This resolves one FIXME in `recover_intersection_pat` by always applying `MachineApplicable` when suggesting, as `bindings_after_at` is now stable.
This also separates a test to apply `// run-rustfix`.

Add env variables and cwd to the shell-like debug output.
Also use the alternate syntax to display a more verbose display, while not showing internal fields and hiding fields when they have their default value.

Fix incorrect span when using byte-escaped rbrace
Fix #103826, a format args span issue introduced in #102214.
The current solution for tracking skipped characters made it so that certain situations were ambiguous enough that the original span couldn't be worked out later. This PR improves on the original solution by keeping track of groups of skipped characters using a map, and fixes the previous bug. See an example of this ambiguity in the [previous PR's discussion](https://github.com/rust-lang/rust/pull/102214#issuecomment-1258711015).

Don't perform invalid checks in `codegen_attrs`
The attributes `#[track_caller]` and `#[cmse_nonsecure_entry]` are only valid on functions. When validating one of these attributes, codegen_attrs previously called `fn_sig`, [which can only be used on functions](https://github.com/rust-lang/rust/pull/105201), on the item the attribute was attached to, assuming that the item was a function without checking. This led to [ICEs in situations where the attribute was incorrectly used on non-functions](https://github.com/rust-lang/rust/issues/105594).
With this change, we skip calling `fn_sig` if the item the attribute is attached to must be a function but isn't, because `check_attr` will reject such cases without codegen_attrs's intervention.
As a side note, some of the attributes in codegen_attrs are only valid on functions, but that property isn't actually checked. I'm planning to fix that in a follow up PR since it's a behavior change that will need to be validated rather than an obvious bugfix. Thankfully, all the attributes like that I've found so far are unstable.
Fixes #105594.

abort immediately on bad mem::zeroed/uninit
Now that we have non-unwinding panics, let's use them for these assertions. This re-establishes the property that `mem::uninitialized` and `mem::zeroed` will never unwind -- the earlier approach of causing panics here sometimes led to hard-to-debug segfaults when the surrounding code was not able to cope with the unexpected unwinding.
Cc `@bjorn3` I did not touch cranelift but I assume it needs a similar patch. However it has a `codegen_panic` abstraction that I did not want to touch since I didn't know how else it is used.

Codegen test for derived `<` on trivial newtype [TEST ONLY]
I originally wrote this for #106065, but the libcore changes there aren't necessarily a win.
So I pulled out this test to be its own PR since it's important (see https://github.com/rust-lang/rust/pull/105840#discussion_r1056030324) and well-intentioned changes to core or the derive could accidentally break it without that being obvious (other than by massive unexplained perf changes).
