This pulls in the weak-intrinsics feature (which currently defaults off), and a minor version update to libm for the compiler_builtins crate to 0.2.7.
"only accepted on the nightly compiler" is misleading when this *is* nightly.
…lcnr Use `ObligationCtxt` in custom type ops We already make one when evaluating the `CustomTypeOp`, so it's simpler to just pass it to the user. Removes a redundant `ObligationCtxt::new_in_snapshot` usage and simplifies some other code. This makes several refactorings related to opaque types in the new solver simpler, but those are not included in this PR.
Expose more information in `get_body_with_borrowck_facts` Verification tools for Rust such as, for example, Creusot or Prusti would benefit from having access to more information computed by the borrow checker. As a first step in that direction, rust-lang#86977 added the `get_body_with_borrowck_facts` API, allowing compiler consumers to obtain a `mir::Body` with accompanying borrow checker information. At RustVerify 2023, multiple people working on verification tools expressed their need for a more comprehensive API. While eventually borrow information could be part of Stable MIR, in the meantime, this PR proposes a more limited approach, extending the existing `get_body_with_borrowck_facts` API. In summary, we propose the following changes: - Permit obtaining the borrow-checked body without necessarily running Polonius - Return the `BorrowSet` and the `RegionInferenceContext` in `BodyWithBorrowckFacts` - Provide a way to compute the `borrows_out_of_scope_at_location` map - Make some helper methods public This is similar to rust-lang#108328 but smaller in scope. `@smoelius` Do you think these changes would also be sufficient for your needs? r? `@oli-obk` cc `@JonasAlaif`
Roll compiler_builtins to 0.1.92 This pulls in the weak-intrinsics feature (which currently defaults off), and a minor version update to libm for the compiler_builtins crate to 0.2.7.
…mpiler, r=petrochenkov Use `Option::is_some_and` and `Result::is_ok_and` in the compiler `.is_some_and(..)`/`.is_ok_and(..)` replace `.map_or(false, ..)` and `.map(..).unwrap_or(false)`, making the code more readable. This PR is a sibling of rust-lang#111873 (comment)
