See rust-lang#80045 (comment) Coverage statements are moved to the beginning of the BCB. This does also affect what's counted before a panic, changing some results, but I think these results may even be preferred? In any case, there are no guarantees about what's counted when a panic occurs (by design).
Integer types have a `count_ones` method that end up calling `intrinsics::ctpop`. On some architectures, that intrinsic is translated as a corresponding CPU instruction know as "popcount" or "popcnt". This PR makes it so that searching for those names in rustdoc shows those methods. CC https://blog.rust-lang.org/2020/11/19/Rust-1.48.html#adding-search-aliases
…thewjasper Implement if-let match guards Implements rust-lang/rfcs#2294 (tracking issue: rust-lang#51114). I probably should do a few more things before this can be merged: - [x] Add tests (added basic tests, more advanced tests could be done in the future?) - [x] Add lint for exhaustive if-let guard (comparable to normal if-let statements) - [x] Fix clippy However since this is a nightly feature maybe it's fine to land this and do those steps in follow-up PRs. Thanks a lot `@matthewjasper` ❤️ for helping me with lowering to MIR! Would you be interested in reviewing this? r? `@ghost` for now
Allow `since="TBD"` for rustc_deprecated Closes rust-lang#78381. This PR only affects `#[rustc_deprecated]`, not `#[deprecated]`, so there is no effect on any stable language feature. Likewise this PR only implements `since="TBD"`, it does not actually tag any library functions with it, so there is no effect on any stable API. Overview of changes: * `rustc_middle/stability.rs`: * change `deprecation_in_effect` function to return `false` when `since="TBD"` * tidy up the compiler output when a deprecated item has `since="TBD"` * `rustc_passes/stability.rs`: * allow `since="TBD"` to pass the sanity check for stable_version < deprecated_version * refactor the "invalid stability version" and "invalid deprecation version" error into separate errors * rustdoc: make `since="TBD"` message on a deprecated item's page match the command-line deprecation output * tests: * test rustdoc output * test that the `deprecated_in_future` lint fires when `since="TBD"` * test the new "invalid deprecation version" error message
Fix issue rust-lang#78496 EarlyOtherwiseBranch finds MIR structures like: ``` bb0: { ... _2 = discriminant(X) ... switchInt(_2) -> [1_isize: bb1, otherwise: bb3] } bb1: { ... _3 = discriminant(Y) ... switchInt(_3) -> [1_isize: bb2, otherwise: bb3] } bb2: {...} bb3: {...} ``` And transforms them into something like: ``` bb0: { ... _2 = discriminant(X) _3 = discriminant(Y) _4 = Eq(_2, _3) switchInt(_4) -> [true: bb4, otherwise: bb3] } bb2: {...} // unchanged bb3: {...} // unchanged bb4: { switchInt(_2) -> [1_isize: bb2, otherwise: bb3] } ``` But that is not always a safe thing to do -- sometimes the early `otherwise` branch is necessary so the later block could assume the value of `discriminant(X)`. I am not totally sure what's the best way to detect that, but fixing rust-lang#78496 should be easy -- we just check if `X` is a sub-expression of `Y`. A more precise test might be to check if `Y` contains a `Downcast(1)` of `X`, but I think this might be good enough. Fix rust-lang#78496

…=matthewjasper Remove unused `TyEncoder::tcx` required method Unsure if this is helpful or not... r? ``@ghost`` cc ``@matthewjasper`` ``@jackh726``
Test that `core::assert!` is valid Closes rust-lang#55482. r? `@dtolnay`
…2.1, r=tmandry Fixed conflict with drop elaboration and coverage See rust-lang#80045 (comment) Coverage statements are moved to the beginning of the BCB. This does also affect what's counted before a panic, changing some results, but I think these results may even be preferred? In any case, there are no guarantees about what's counted when a panic occurs (by design). r? `@tmandry` FYI `@wesleywiser` `@ecstatic-morse`
…r=varkor Add support for target aliases Closes rust-lang#68214, see that for more info. `@varkor`
…k-Simulacrum Revert rust-lang#78790 - rust-src vendoring This reverts the rust-src vendor changes from rust-lang#78790. There were a few issues (see rust-lang#79218, rust-lang/cargo#8962, rust-lang/cargo#8963), that I don't think will get fixed in the next few days before the beta branch. Fixes rust-lang#79218
Add `popcount` and `popcnt` as doc aliases for `count_ones` methods. Integer types have a `count_ones` method that end up calling `intrinsics::ctpop`.
