implicit `Option`-returning doctests
This distinguishes `Option` and `Result`-returning doctests with implicit `main` method, where the former tests must end with `Some(())`.
Open question: Does this need a feature gate?

Fix linkage diagnostic so it doesn't ICE for external crates
Fix linkage diagnostic so it doesn't ICE for external crates
(As a drive-by improvement, improved the diagnostic to indicate *why* `*const T` or `*mut T` is required.)
Fix#59548Fix#61232
Emit error when trying to use PGO in conjunction with unwinding on Windows.
This PR makes `rustc` emit an error when trying use PGO in conjunction with `-Cpanic=unwind` on Windows, isn't supported by LLVM yet. The error messages points to https://github.com/rust-lang/rust/issues/61002, which documents this known limitation.
Warn on bare_trait_objects by default
The `bare_trait_objects` lint is set to `warn` by default.
Most ui tests have been updated to use `dyn` to avoid creating noise in stderr files.

do not print panic message on doctest failures
This PR cleans up rustdoc test output by silently unwinding on failure instead of using `panic!`. It also improves the clarity and consistency of the output on test failure, and adds test cases for failure modes that were previously untested.
This commit fixes a ICE where struct constructors were resulting in an
ICE with const generics. Previously, a `match` in `type_of` did not have
an arm for the `DefKind::Ctor` resolutions and therefore would assume
that the type did not have generics.
Add Step::sub_usize
Required for #54054.
I'm aware that the `Step` trait needs a rework, but this still seems like a reasonable addition?
This currently doesn't compile because Chalk contains a type that implement this trait, and this is a breaking change. How can that be fixed?
tests: Centralize proc macros commonly used for testing
Many proc macros in `ui\proc-macro\auxiliary` were doing same things.
(I added a fair share of those myself.)
Now commonly used macros (empty, identity, etc) are collected in one place - `ui\proc-macro\auxiliary\test-macros.rs`.
Changes the type `mir::Mir` into `mir::Body`
Fixes part 1 of #60229 (previously attempted in #60242).
I stumbled upon the issue and it seems that the previous attempt at solving it was not merged. This is a second try more up-to-date.
The commit should have changed comments as well.
At the time of writting, it passes the tidy and check tool.
