2022-11-17Auto merge of #104170 - cjgillot:hir-def-id, r=fee1-deadbors-11/+11
Record `LocalDefId` in HIR nodes instead of a side table This is part of an attempt to remove the `HirId -> LocalDefId` table from HIR. This attempt is a prerequisite to creation of `LocalDefId` after HIR lowering (https://github.com/rust-lang/rust/pull/96840), by controlling how `def_id` information is accessed. This first part adds the information to HIR nodes themselves instead of a table. The second part is https://github.com/rust-lang/rust/pull/103902 The third part will be to make `hir::Visitor::visit_fn` take a `LocalDefId` as last parameter. The fourth part will be to completely remove the side table.

2022-10-29Rename some `OwnerId` fields.Nicholas Nethercote-12/+12
spastorino noticed some silly expressions like `item_id.def_id.def_id`. This commit renames several `def_id: OwnerId` fields as `owner_id`, so those expressions become `item_id.owner_id.def_id`. `item_id.owner_id.local_def_id` would be even clearer, but the use of `def_id` for values of type `LocalDefId` is *very* widespread, so I left that alone.

2022-08-12Auto merge of #100328 - davidtwco:perf-implications, r=nnethercotebors-36/+91
passes: load `defined_lib_features` query less Hopefully addresses the perf regressions from #99212 (see #99905). Re-structure the stability checks for library features to avoid calling `defined_lib_features` for any more crates than necessary for each of the implications or local feature attributes that need validation. r? `@ghost` (just checking perf at first)

2022-08-11Simplify `rustc_hir::intravisit::Visitor::visit_variant_data`.Nicholas Nethercote-5/+5
It has four arguments that are never used. This avoids lots of argument passing in functions that feed into `visit_variant_data`.

2022-07-31Don't track parent body stability (it wasn't used anyway)Maybe Waffle-18/+3
2022-07-26Implement `#[rustc_default_body_unstable]`Maybe Waffle-4/+32
This attribute allows to mark default body of a trait function as unstable. This means that implementing the trait without implementing the function will require enabling unstable feature. This is useful in conjunction with `#[rustc_must_implement_one_of]`, we may want to relax requirements for a trait, for example allowing implementing either of `PartialEq::{eq, ne}`, but do so in a safe way -- making implementation of only `PartialEq::ne` unstable.

2022-07-20passes: check implied feature existsDavid Wood-19/+31
Add a check confirming that features referenced in `implied_by` meta items actually exist. Signed-off-by: David Wood <david.wood@huawei.com>
2022-07-20passes: improved partial stabilization diagnosticDavid Wood-8/+50
Improves the diagnostic when a feature attribute is specified unnecessarily but the feature implies another (i.e. it was partially stabilized) to refer to the implied feature. Signed-off-by: David Wood <david.wood@huawei.com>
2022-07-20middle: add `implies_by` to `#[unstable]`David Wood-0/+1
If part of a feature is stabilized and a new feature is added for the remaining parts, then the `implied_by` attribute can be used to indicate which now-stable feature previously contained a item. If the now-stable feature is still active (if the user has only just updated rustc, for example) then there will not be an stability error for uses of the item from the implied feature.

2022-07-14Auto merge of #95956 - yaahc:stable-in-unstable, r=cjgillotbors-3/+48
Support unstable moves via stable in unstable items part of https://rust-lang.zulipchat.com/#narrow/stream/131828-t-compiler/topic/moving.20items.20to.20core.20unstably and a blocker of https://github.com/rust-lang/rust/pull/90328. The libs-api team needs the ability to move an already stable item to a new location unstably, in this case for Error in core. Otherwise these changes are insta-stable making them much harder to merge. This PR attempts to solve the problem by checking the stability of path segments as well as the last item in the path itself, which is currently the only thing checked.
