2022-08-17Rollup merge of #100621 - taiki-e:armv4t-atomics-32, r=cuviperMatthias Krüger-2/+6
Pass +atomics-32 feature for {arm,thumb}v4t-none-eabi Similar to https://github.com/rust-lang/rust/commit/89582e8193e0da64a54c4ffae7f9fa64ed9fe2af, but for ARMv4t. Pre-v6 ARM target does not have atomic CAS, except for Linux and Android where atomic CAS is provided by compiler-builtins. So, there is a similar issue as thumbv6m. I have confirmed that enabling the `atomics-32` target feature fixes the problem in the project affected by this issue.

2022-08-17Rollup merge of #100532 - RalfJung:unwind-miri, r=Mark-SimulacrumMatthias Krüger-1/+7
unwind: don't build dependency when building for Miri This is basically re-submitting https://github.com/rust-lang/rust/pull/94813. In that PR there was a suggestion to instead have bootstrap set a `RUST_CHECK` env var and use that rather than doing something Miri-specific. However, such an env var would mean that when switching between `./x.py check` and `./x.py build`, the build script gets re-run each time, which doesn't seem good. So I think for now checking for Miri probably causes fewer problems. r? ````@Mark-Simulacrum````

2022-08-17Rollup merge of #100389 - compiler-errors:return-type-suggestion-cycle, ↵Matthias Krüger-0/+75
r=cjgillot Do not report cycle error when inferring return type for suggestion The UI test is a good example of a case where this happens. The cycle is due to needing the value of the return type `-> _` to compute the variances of items in the crate, but then needing the variances of the items in the crate to do typechecking to infer what `-> _`'s real type is. Since we're already gonna emit an error in astconv, just delay the cycle bug as an error.

2022-08-17Rollup merge of #99972 - RalfJung:1zst, r=lcnrMatthias Krüger-1/+3
interpret: only consider 1-ZST when searching for receiver `repr(transparent)` currently entirely rejects ZST with alignment larger than 1 (which is odd, arguably [this](https://play.rust-lang.org/?version=stable&mode=debug&edition=2021&gist=02870f29396fa948c3123cb53d869ad1) should be accepted), so this should be safe. And if it ever isn't safe then that is very likely a bug elsewhere in the compiler.
2022-08-17Rollup merge of #99474 - aDotInTheVoid:rustdoc-json-noinline-test-cleanup, ↵Matthias Krüger-39/+111
r=CraftSpider Rustdoc json tests: New @hasexact test command Alot of the time, we wanted to assert that a module had an exact set of items. Most of the time this was done by asserting that the ```@count``` of the module was `n`, and then doing `n` ```@has``` checks on the module. This was tedious, so often shortcuts were done. This PR adds a new command to jsondocck to allow consistently expressing this behavior, and then uses it to clean up the tests. ``@rustbot`` modify labels: +A-rustdoc-json +A-testsuite

r=cjgillot Fix nonsense non-tupled `Fn` trait error Given this code: ```rust #![feature(unboxed_closures)] fn a<F: Fn<usize>>(f: F) {} fn main() { a(|_: usize| {}); } ``` We currently emit this error: ``` error[E0631]: type mismatch in closure arguments --> src/main.rs:6:5 | 6 | a(|_: usize| {}); | ^ ---------- found signature of `fn(usize) -> _` | | | expected signature of `fn(usize) -> _` | note: required by a bound in `a` --> src/main.rs:3:9 | 3 | fn a<F: Fn<usize>>(f: F) {} | ^^^^^^^^^ required by this bound in `a` For more information about this error, try `rustc --explain E0631`. error: could not compile `playground` due to previous error ``` Notably, it says the same thing for "expected" and "found"! Fix the output so that we instead emit: ``` error[E0308]: mismatched types --> /home/gh-compiler-errors/test.rs:6:5 | 6 | a(|_: usize| {}); | ^ types differ | = note: expected trait `Fn<usize>` found trait `Fn<(usize,)>` note: required by a bound in `a` --> /home/gh-compiler-errors/test.rs:3:9 | 3 | fn a<F: Fn<usize>>(f: F) {} | ^^^^^^^^^ required by this bound in `a` error: aborting due to previous error ``` The error could still use some work, namely the "mismatched types" part, but I'm leaving it a bit rough since the only way you'd ever get this error is when you're messing with `#![feature(unboxed_closures)]`. Simply making sure we actually print out the difference in trait-refs is good enough for me. I could probably factor in some additional improvements if those are desired.

2022-08-16Rollup merge of #100600 - saethlin:rename-memory-hooks, r=RalfJungMatthias Krüger-8/+14
Rename Machine memory hooks to suggest when they run Some of the other memory hooks start with `before_` or `after_` to indicate that they run before or after a certain operation. These don't, so I was a bit confused as to when they are supposed to run. `memory_read` can be read two ways in English, "memory was read" or "this is a memory read" so without the prefix this was especially ambiguous.
