…e consumes its upvars
This includes [1] which means we can remove the (nonworking) configuration of `no-f16-f128`. Fixes rust-lang#128401. [1]: rust-lang/compiler-builtins#652
The default repository server setting has changed on Fuchsia (default is newly "false"). Now, in order to start the repository server, the config `repository.server.enabled` must be set to true.
…ce-move, r=BoxyUwU Skip over args when determining if async-closure's inner coroutine consumes its upvars rust-lang#125306 implements a strategy for when we have an `async move ||` async-closure that is inferred to be `async FnOnce`, it will force the inner coroutine to also be `move`, since we cannot borrow any upvars from the parent async-closure (since `FnOnce` is not lending): https://github.com/rust-lang/rust/blob/8e86c9567154dc5a9ada15ab196d23eae2bd7d89/compiler/rustc_hir_typeck/src/upvar.rs#L211-L229 However, when this strategy was implemented, it reused the `ExprUseVisitor` data from visiting the whole coroutine, which includes additional statements due to `async`-specific argument desugaring: https://github.com/rust-lang/rust/blob/8e86c9567154dc5a9ada15ab196d23eae2bd7d89/compiler/rustc_ast_lowering/src/item.rs#L1197-L1228 Well, it turns out that we don't care about these argument desugaring parameters, because arguments to the async-closure are not the *async-closure*'s captures -- they exist for only one invocation of the closure, and they're always consumed by construction (see the argument desugaring above), so they will force the coroutine's inferred kind to `FnOnce`. (Unless they're `Copy`, because we never consider `Copy` types to be consumed): https://github.com/rust-lang/rust/blob/8e86c9567154dc5a9ada15ab196d23eae2bd7d89/compiler/rustc_hir_typeck/src/expr_use_visitor.rs#L60-L66 However, since we *were* visiting these arg exprs, this resulted in us too-aggressively applying `move` to the inner coroutine, resulting in regressions. For example, this PR fixes rust-lang#128516. Fascinatingly, the note above about how we never consume `Copy` types is why this only regressed when the argument types weren't all `Copy`. I tried to leave some comments inline to make this more clear :)
…pos, r=BoxyUwU Emit an error for invalid use of the `#[no_sanitize]` attribute fixes rust-lang#128487. Currently, the use of the `#[no_sanitize]` attribute for Mod, Impl,... is incorrectly permitted. This PR will correct this issue by generating errors, and I've also added some UI test cases for it. Referenced rust-lang#128458. As far as I know, the `#[no_sanitize]` attribute can only be used with functions, so I changed that part to `Fn` and `Method` using `check_applied_to_fn_or_method`. However, I couldn't find explicit documentation on this, so I could be mistaken...

… r=tmandry Fuchsia Test Runner: enable ffx repository server The default repository server setting has changed on Fuchsia (default is newly "false"). Now, in order to start the repository server, the config `repository.server.enabled` must be set to true.
…=petrochenkov refactor(rustc_expand::mbe): Don't require full ExtCtxt when not necessary Refactor `mbe::diagnostics::failed_to_match_macro()` to not require a full `ExtCtxt`, but only a `&ParseSess`. It hard-required the `ExtCtxt` only for a call to `cx.trace_macros_diag()`, which we move instead to the only call-site of the function. Note: This could be a potential change in observed behavior, because a call to `cx.trace_macros_diag()` now always happens after `failed_to_match_macro()` was called, where before it was only called at the end of the main return path of the function. But since `trace_macros_diag()` "flushes" out any not-yet-reported errors, it should be ok to call it for all paths, since there shouldn't be any on the non-main paths I think. However, I don't know the rest of the codebase well enough to say that with 100% confidence, but `tests/ui` still pass, which gives at least some confidence in the change. Also concretize the return type from `Box<dyn MacResult>` to `(Span, ErrorGuaranteed)`, because this function will _always_ return an error, and never any other kind of result. Was part of rust-lang#128605 and rust-lang#128747, but is a standalone refactoring. r? ``@petrochenkov``
