002287d25f Auto merge of #68544 - Aaron1011:remove-overlapping-traits, r=estebank
Remove the `overlapping_marker_traits` feature

See #29864

This has been replaced by `#[feature(marker_trait_attr)]`

A few notes:

* Due to PR #68057 not yet being in the bootstrap compiler, it's
  necessary to continue using `#![feature(overlapping_marker_traits)]`
  under `#[cfg(bootstrap)]` to work around type inference issues.
* I've updated tests that used `overlapping_marker_traits` to now use
  `marker_trait_attr` where applicable

The test `src/test/ui/overlap-marker-trait.rs` doesn't make any sense
now that `overlapping_marker_traits`, so I removed it.

The test `src/test/ui/traits/overlap-permitted-for-marker-traits-neg.rs`
now fails, since it's no longer possible to have multiple overlapping
negative impls of `Send`. I believe that this is the behavior we want
(assuming that `Send` is not going to become a `#[marker]` trait, so I
renamed the test to `overlap-permitted-for-marker-traits-neg`

Rollup merge of #68758 - daboross:fix-59191, r=petrochenkov
Fix 59191 - ICE when macro replaces crate root with non-module item

Hi,

This should fix #59191! My friend and I are working on learning the rustc codebase through contributions, so please feel free to mention anything amiss or that could be done better.

The code adds an explicit case for when a macro applied to the crate root (via an inner attribute) replaces it with something nonsensical, like a function. The crate root must be a module, and the error message reflects this.

---

I should note that there are a few other weird edge cases here, like if they do output a module, it succeeds but uses that module's name as a prefix for all names in the crate. I'm assuming that's an issue for stabilizing #54726, though.

Instrument C / C++ in MemorySanitizer example

Modify the example to instrument C / C++ in addition to Rust, since it
will be generally required (e.g., when using libbacktrace for symbolication).

c9290dceee Auto merge of #68558 - HeroicKatora:buf-writer-capacity, r=alexcrichton
Add a method to query the capacity of a BufWriter and BufReader

Besides the obvious of retrieving the parameter used to construct the writer, this method allows consumers to control the number of `flush` calls during write operations. For `BufReader` it gives an upper bound on the returned buffer in `fill_buf` which might influence the allocation behaviour of a consumer.

Always use lazy qualif getters during const-checking

`has_mut_interior_eager_seek` was needed to work around an overly restrictive bound on the `per_local` argument to the `Qualif` trait. This PR makes that bound `FnMut` instead of `Fn` so we can seek cursors inside of it, resolving a FIXME in the const-checking code.

Implement MIR lowering for or-patterns

This is the last thing needed to get meaningful run-pass tests for or-patterns. There probably need to be more tests before stabilizing this, but the most important cases should have been covered.

Note: we can generate exponentially large MIR CFGs when using or-patterns containing bindings, type ascriptions, or that are for a match arm with a guard. `src/test/mir-opt/exponential-or.rs` shows the best case for what we currently do.
