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.

Change some regular comments into documentation comments. Signed-off-by: David Wood <david.wood@huawei.com>
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.
2022-07-14Auto merge of #98975 - jyn514:unstable_opts, r=wesleywiserbors-2/+2
Rename `debugging_opts` to `unstable_opts` This is no longer used only for debugging options (e.g. `-Zoutput-width`, `-Zallow-features`). Rename it to be more clear. cc https://rust-lang.zulipchat.com/#narrow/stream/131828-t-compiler/topic/Codegen.20options.20.2F.20debugging.20options r? `@Amanieu` cc `@nikic` `@joshtriplett`

2022-05-19Move check to existing passJacob Pratt-56/+26
This alters the diagnostics a bit, as the trait method is still stable. The only thing this check does is ensure that compilation fails if a trait implementation is declared const-stable.
2022-05-19Proper const stability check, default to unstableJacob Pratt-1/+52
Rather than deferring to const eval for checking if a trait is const, we now check up-front. This allows the error to be emitted earlier, notably at the same time as other stability checks. Also included in this commit is a change of the default const stability level to UNstable. Previously, an item that was `const` but did not explicitly state it was unstable was implicitly stable.
2022-05-19Add and use stability helper methodsJacob Pratt-5/+3
This avoids an ambiguity (when reading) where `.level.is_stable()` is not immediately clear whether it is general stability or const stability.

There are a few places were we have to construct it, though, and a few places that are more invasive to change. To do this, we create a constructor with a long obvious name.
