Rollup merge of rust-lang#123979 - oli-obk:define_opaque_types7, r=compiler-errors Subtype predicates only exist on inference types, so we can allow them to register opaque types within them. We were unable to come up with an example where this could be reached (subtype predicates with either side not being an infer var gets consumed during any `select_where_possible` invocation, of which we have a lot in typeck). To ensure we don't silently accept new behaviour in case we missed a situation where this could occur, I have added an assert that prevents opaque types from having their hidden type constrained. r? `@compiler-errors`

Add a fast-path to `Debug` ASCII `&str` Instead of going through the `EscapeDebug` machinery, we can just skip over ASCII chars that don’t need any escaping. Introduce printable-ASCII fast-path for `impl Debug for str` Instead of having a single loop that works on utf-8 `char`s, this splits the implementation into a loop that quickly skips over printable ASCII, falling back to per-char iteration for other chunks. Switch to primarily using `&str` Surprisingly, benchmarks have shown that using `&str` instead of `&[u8]` with some `unsafe` code is actually faster. Process a single not-ASCII-printable `char` per iteration This avoids having to collect a non-ASCII-printable run before processing it. std: simplify key-based thread locals std: clean up the TLS implementation Make clamp inline Run rustfmt on files that need it. Somehow these files aren't properly formatted. By default `x fmt` and `x tidy` only check files that have changed against master, so if an ill-formatted file somehow slips in it can stay that way as long as it doesn't get modified(?) I found these when I ran `x fmt` explicitly on every `.rs` file in the repo, while working on rust-lang/compiler-team#750. Fix the dead link in the bootstrap README Notify kobzol after changes to `opt-dist` Revert "Rollup merge of rust-lang#123979 - oli-obk:define_opaque_types7, r=compiler-errors" This reverts commit f939d1f, reversing changes made to 183c706. Add regression tests Only suppress binop error in favor of semicolon suggestion if we're in an assignment statement compiler: const_eval/transform/validate.rs -> mir_transform/validate.rs compiler: unnest rustc_const_eval::check_consts clippy: unnest check_consts miri: receive the blessings of validate.rs Migrate `run-make/rustdoc-with-output-dir-option` to `rmake.rs` Fix some SIMD intrinsics documentation Actually just remove the special case altogether rustdoc-json: Add test for keywords with `--document-private-items` tag more stuff with `WG-trait-system-refactor` Warn/error on self ctor from outer item in inner item (Mostly) revert "Account for type param from other item in `note_and_explain`" This mostly reverts commit 7449478. It also removes an `opt_param_at` that really is unnecessary given our ICE policy for malformed intrinsics. Update cargo use posix_memalign on most Unix targets fix typo Co-authored-by: Jubilee <[email protected]> Fail relating constants of different types Use regular type equating instead of a custom query Bump bootstrap compiler to the latest beta compiler Remove now outdated comment since we bumped stage0 Stop using the avx512er and avx512pf x86 target features They are no longer supported by LLVM 19. Fixes rust-lang#125492 remove proof tree formatter, make em shallow Don't eagerly monomorphize drop for types that are impossible to instantiate Better ICE message for unresolved upvars Structurally resolve before builtin_index in EUV Add manual Sync impl for ReentrantLockGuard Fixes: rust-lang#125526

…-errors Allow constraining opaque types during subtyping in the trait system Previous attempt: rust-lang#123979 Sometimes we don't immediately perform subtyping, but instead register a subtyping obligation and solve that obligation when its inference variables become resolved. Unlike immediate subtyping, we currently do not allow registering hidden types for opaque types. This PR also allows that.
