2021-04-26Auto merge of #84546 - CohenArthur:fix-liveness-typo, r=jyn514bors-3/+3
Fix typo in report_unsed_assign The function was called `report_unsed_assign`, which I assume is a typo, considering the rest of the file. This replaces `report_unsed_assign` with `report_unused_assign`.

2021-04-24Auto merge of #84310 - RalfJung:const-fn-feature-flags, r=oli-obkbors-1/+0
further split up const_fn feature flag This continues the work on splitting up `const_fn` into separate feature flags: * `const_fn_trait_bound` for `const fn` with trait bounds * `const_fn_unsize` for unsizing coercions in `const fn` (looks like only `dyn` unsizing is still guarded here) I don't know if there are even any things left that `const_fn` guards... at least libcore and liballoc do not need it any more. `@oli-obk` are you currently able to do reviews?

Match against attribute name when validating attributes Extract attribute name once and match it against symbols that are being validated, instead of using `Session::check_name` for each symbol individually. Assume that all validated attributes are used, instead of marking them as such, since the attribute check should be exhaustive.

2021-04-07Rollup merge of #83916 - Amanieu:asm_anonconst, r=petrochenkovDylan DPC-6/+7
Use AnonConst for asm! constants This replaces the old system which used explicit promotion. See #83169 for more background. The syntax for `const` operands is still the same as before: `const <expr>`. Fixes #83169 Because the implementation is heavily based on inline consts, we suffer from the same issues: - We lose the ability to use expressions derived from generics. See the deleted tests in `src/test/ui/asm/const.rs`. - We are hitting the same ICEs as inline consts, for example #78174. It is unlikely that we will be able to stabilize this before inline consts are stabilized.

Rename `#[doc(spotlight)]` to `#[doc(notable_trait)]` Fixes #80936. "spotlight" is not a very specific or self-explaining name. Additionally, the dialog that it triggers is called "Notable traits". So, "notable trait" is a better name. * Rename `#[doc(spotlight)]` to `#[doc(notable_trait)]` * Rename `#![feature(doc_spotlight)]` to `#![feature(doc_notable_trait)]` * Update documentation * Improve documentation r? `@Manishearth`

2021-03-25Auto merge of #83424 - cjgillot:noparam, r=lcnrbors-13/+0
GenericParam does not need to be a HIR owner. The special case is not required. Universal impl traits design to regular generic parameters, and their content is owned by the enclosing item. Existential (and opaque) impl traits generate their own enclosing item, and are collected through it.
2021-03-24Auto merge of #75384 - JulianKnodt:cg_def, r=varkor,lcnrbors-4/+3
implement `feature(const_generics_defaults)` Implements const generics defaults `struct Example<const N: usize=3>`, as well as a query for getting the default of a given const-parameter's def id. There are some remaining FIXME's but they were specified as not blocking for merging this PR. This also puts the defaults behind the unstable feature gate `#![feature(const_generics_defaults)]`. ~~This currently creates a field which is always false on `GenericParamDefKind` for future use when consts are permitted to have defaults. I'm not sure if this is exactly what is best for adding default parameters, but I mimicked the style of type defaults, so hopefully this is ok.~~ r? `@lcnr`

Replace closures_captures and upvar_capture with closure_min_captures Removed all uses of closures_captures and upvar_capture and refactored code to work with closure_min_captures.

This change makes it easier to follow the control flow. I also moved the end-of-line comments attached to some symbols to before the symbol listing. This allows rustfmt to format the code; otherwise no formatting occurs (see rust-lang/rustfmt#4750).
