Currently a test without a `failure-status` directive is treated as having an
expected failure-status of 1, but `run-coverage` tests will want to treat those
tests as expecting success instead.
This will allow the `run-coverage` mode to easily set environment variable
`LLVM_PROFILE_FILE`, and to prevent the executable from being deleted after a
successful run.
Add tests impl via obj unless denied
Fixes#112737
Add simple tests to check feature change in #112320 is performing as expected.
Note:
- Unsure about filenames, locations & function signature names (tried to make them something sensible)
Make `UnwindAction::Continue` explicit in MIR dump
Makes it easier to spot unwinding related issues in MIR by making `UnwindAction::Continue` explicit, just like all other `UnwindAction`s.
Allow comparing `Box`es with different allocators
Currently, comparing `Box`es over different allocators is not allowed:
```Rust
error[E0308]: mismatched types
--> library/alloc/tests/boxed.rs:22:20
|
22 | assert_eq!(b1, b2);
| ^^ expected `Box<{integer}, ConstAllocator>`, found `Box<{integer}, AnotherAllocator>`

= note: expected struct `Box<{integer}, ConstAllocator>`
found struct `Box<{integer}, AnotherAllocator>`
For more information about this error, try `rustc --explain E0308`.
error: could not compile `alloc` (test "collectionstests") due to previous error

This PR lifts this limitation
Make compiletest aware of targets without dynamic linking
Some parts of the compiletest internals and some tests require dynamic linking to work, which is not supported by all targets. Before this PR, this was handled by if branches matching on the target name.
This PR loads whether a target supports dynamic linking or not from the target spec, and adds a `// needs-dynamic-linking` attribute for tests that require it. Note that I was not able to replace all the old conditions based on the target name, as some targets have `dynamic_linking: true` in their spec but pretend they don't have it in compiletest.
Also, to get this to work I had to *partially* revert #111472 (cc `@djkoloski` `@tmandry` `@bjorn3).` On one hand, only the target spec contains whether a target supports dynamic linking, but on the other hand a subset of the fields can be overridden through `-C` flags (as far as I'm aware only `-C panic=$strategy`). The solution I came up with is to take the target spec as the base, and then override the panic strategy based on `--print=cfg`. Hopefully that should not break y'all again.
Add trustzone and virtualization target features for aarch32.
These are LLVM target features which allow the `smc` and `hvc` instructions respectively to be used in inline assembly.
`thir`: Add `Become` expression kind
This PR is pretty small and just adds `thir::ExprKind::Become`. I didn't include the checks that will be done on thir, since they are much more complicated and can be done in parallel with with MIR (or, well, at least I believe they can).

Export AnalysisResults trait in rustc_mir_dataflow
Followup to https://github.com/rust-lang/rust/pull/108293
Re-exports the new trait defined in mentioned PR to make ResultsCursor::seek_before_primary_effect, ResultsCursor::seek_after_primary_effect... usable again outside the compiler itself.
Use `CoverageKind::as_operand_id` instead of manually reimplementing it
These two pieces of code are functionally equivalent to the `CoverageKind::as_operand_id` method that already exists, and is already used elsewhere in this file.
This slightly reduces the amount of code that manually pattern-matches on `CoverageKind`.
bootstrap: rename 'user' profile to 'dist'
Fixes#112074
Unfortunately a big chunk of the diff is adding `PartialEq/Eq/Debug` impls so we can `assert_eq` but I think better to have them in the long run.
For back compat, ensure `"maintainer"`, `"user"` and `"dist"` are all parsed as `Profile::Dist`.

Migrate `TyCtxt::predicates_of` and `ParamEnv::caller_bounds` to `Clause`
The last big change in the series.
I will follow-up with additional filed issues once this PR lands:
- [ ] Investigate making `TypeFoldable<TyCtxt<'tcx>> for ty::Clause<'tcx>` implementation less weird: 2efe091705/compiler/rustc_middle/src/ty/structural_impls.rs (L672)
- [ ] Clean up the elaborator since it should only be emitting child clauses, not predicates
- [ ] Rename identifiers like `pred` and `predicates` to `clause` if they're actually clauses around the codebase
- [ ] Validate that all of the `ToPredicate` impls are acutally still needed, or prune them if they're not
r? `@ghost` until the other branch lands
