2023-03-07Rollup merge of #108583 - ↵Matthias Krüger-0/+25
compiler-errors:rpitit-default-method-with-nested-rpitits, r=spastorino Account for binders correctly when adding default RPITIT method assumption As of #108203, we install extra projection predicates into the param-env of a default trait method when it has return-position `impl Trait` (or is async). The implementation didn't account for the fact that it's walking into and out of binders, so we just need to shift all the debruijn indices accordingly when constructing the projection predicates. Fixes #108579 r? types

Use `nuw` when calculating slice lengths from `Range`s An `assume` would definitely not be worth it, but since the flag is almost free we might as well tell LLVM this, especially on `_unchecked` calls where there's no obvious way for it to deduce it.

2023-03-07Auto merge of #108691 - aliemjay:closure-subject, r=jackh726bors-16/+94
fix multiple issues when promoting type-test subject Multiple interdependent fixes. See linked issues for a short description of each. When Promoting a type-test `T: 'a` from within the closure back to its parent function, there are a couple pre-existing bugs and limitations. They were exposed by the recent changes to opaque types because the type-test subject (`T`) is no longer a simple ParamTy.

2023-03-05Use `nuw` when calculating slice lengths from `Range`sScott McMurray-0/+62

2023-03-05Auto merge of #108157 - scottmcm:tuple-gt-via-partialcmp, r=dtolnaybors-0/+121
Use `partial_cmp` to implement tuple `lt`/`le`/`ge`/`gt` In today's implementation, `(A, B)::gt` contains calls to *both* `A::eq` *and* `A::gt`. That's fine for primitives, but for things like `String`s it's kinda weird -- `(String, usize)::gt` has a call to both `bcmp` and `memcmp` (<https://rust.godbolt.org/z/7jbbPMesf>) because when `bcmp` says the `String`s aren't equal, it turns around and calls `memcmp` to find out which one's bigger. This PR changes the implementation to instead implement `(A, …, C, Z)::gt` using `A::partial_cmp`, `…::partial_cmp`, `C::partial_cmp`, and `Z::gt`. (And analogously for `lt`, `le`, and `ge`.) That way expensive comparisons don't need to be repeated. Technically this is an observable change on stable, so I've marked it `needs-fcp` + `T-libs-api` and will r? rust-lang/libs-api I'm hoping that this will be non-controversial, however, since it's very similar to the observable changes that were made to the derives (#81384 #98655) -- like those, this only changes behaviour if a type overrode behaviour in a way inconsistent with the rules for the various traits involved. (The first commit here is #108156, adding the codegen test, which I used to make sure this doesn't regress behaviour for primitives.)

rustdoc-json: switch from HashMap to FxHashMap to fix non-determinism Using `HashMap` in `rustdoc_json_types::Crate` were causing creating randomly ordered objects in the json doc files. Which might cause problems to people who are doing comparison on those files specially in CI pipelines. See https://github.com/rust-lang/rust/issues/103785#issuecomment-1307425590 This PR fixes that issue and extends the coverage of `tests/run-make/rustdoc-verify-output-files` testing ability.

Desugaring of drop and replace at MIR build This commit desugars the drop and replace deriving from an assignment at MIR build, avoiding the construction of the `DropAndReplace` terminator (which will be removed in a following PR). In order to retain the same error messages for replaces a new `DesugaringKind::Replace` variant is introduced. The changes in the borrowck are also useful for future work in moving drop elaboration before borrowck, as no `DropAndReplace` would be present there anymore. Notes on test diffs: * `tests/ui/borrowck/issue-58776-borrowck-scans-children`: the assignment deriving from the desugaring kills the borrow. * `tests/ui/async-await/async-fn-size-uninit-locals.rs`, `tests/mir-opt/issue_41110.test.ElaborateDrops.after.mir`, `tests/mir-opt/issue_41888.main.ElaborateDrops.after.mir`: drop elaboration generates (or reads from) a useless drop flag due to an issue with the dataflow analysis. Will be fixed independently by https://github.com/rust-lang/rust/pull/106430. See https://github.com/rust-lang/rust/pull/104488 for more context
