2023-12-15Make `rustc_index::bit_set` available on stableNadrieril-12/+37
2023-11-22Replace `no_ord_impl` with `orderable`.Nicholas Nethercote-0/+1
Similar to the previous commit, this replaces `newtype_index`'s opt-out `no_ord_impl` attribute with the opt-in `orderable` attribute.

Only the impl for `u32` is used. These can be reinstated easily if needed in the future.

2023-08-22Add disclaimer on size assertion macroNilstrieb-0/+7
Sometimes people are inspired by rustc to add size assertions to their code and copy the macro. This is bad because it causes hard build errors. rustc happens to be special where it makes this okay.
2023-08-03Add `internal_features` lintNilstrieb-0/+1
It lints against features that are inteded to be internal to the compiler and standard library. Implements MCP #596. We allow `internal_features` in the standard library and compiler as those use many features and this _is_ the standard library from the "internal to the compiler and standard library" after all. Marking some features as internal wasn't exactly the most scientific approach, I just marked some mostly obvious features. While there is a categorization in the macro, it's not very well upheld (should probably be fixed in another PR). We always pass `-Ainternal_features` in the testsuite About 400 UI tests and several other tests use internal features. Instead of throwing the attribute on each one, just always allow them. There's nothing wrong with testing internal features^^

Use `FieldIdx` in `FieldsShape` Finally got to the main motivating example from https://github.com/rust-lang/compiler-team/issues/606 :)
2023-04-04Use `FieldIdx` in `FieldsShape`Scott McMurray-0/+43
Finally got to the main motivating example from the MCP :)
2023-04-03Doc-comment `IndexVec::from_elem` and use it in a few more placesScott McMurray-0/+11
2023-04-02Use `&IndexSlice` instead of `&IndexVec` where possibleScott McMurray-2/+40
All the same reasons as for `[T]`: more general, less pointer chasing, and `&mut IndexSlice` emphasizes that it doesn't change *length*.
2023-04-01Use `FieldIdx` in various things related to aggregatesScott McMurray-0/+6
Shrank `AggregateKind` by 8 bytes on x64, since the active field of a union is tracked as an `Option<FieldIdx>` instead of `Option<usize>`.
2023-03-30Add `IndexSlice` to go with `IndexVec`Scott McMurray-70/+160
Moves the methods that don't need full `IndexVec`-ness over to `IndexSlice`, and have `IndexVec` deref to `IndexSlice` so everything keeps working.
2023-03-29Rename `IndexVec::last` → `last_index`Scott McMurray-1/+1
As I've been trying to replace a `Vec` with an `IndexVec`, having `last` exist on both but returning very different types makes the transition a bit awkward -- the errors are later, where you get things like "there's no `ty` method on `mir::Field`" rather than a more localized error like "hey, there's no `last` on `IndexVec`". So I propose renaming `last` to `last_index` to help distinguish `Vec::last`, which returns an element, and `IndexVec::last_index`, which returns an index. (Similarly, `Iterator::last` also returns an element, not an index.)
2023-03-21Use `SmallVec` in bitsetsNilstrieb-5/+7
This doesn't increase their size and means that we don't have to heap allocate for small sets.

2023-01-05Fix `uninlined_format_args` for some compiler cratesnils-5/+2
Convert all the crates that have had their diagnostic migration completed (except save_analysis because that will be deleted soon and apfloat because of the licensing problem).
2022-12-18A few small cleanups for `newtype_index`Nilstrieb-1/+1
Remove the `..` from the body, only a few invocations used it and it's inconsistent with rust syntax. Use `;` instead of `,` between consts. As the Rust syntax gods inteded.

2022-07-31Auto merge of #99052 - tmiasko:bitset-clone-from, r=Mark-Simulacrumbors-6/+19
Fix cloning from a BitSet with a different domain size The previous implementation incorrectly assumed that the number of words in a bit set is equal to the domain size. The new implementation delegates to `Vec::clone_from` which is specialized for `Copy` elements. Fixes #99006.
