…enkov Recursive delegation improvements This PR fixes interaction of recently added recursive delegations with other features, such as generics inheritance and attributes inheritance. It fixes rust-lang/rust#150152 ICE, it is a part of the delegation feature rust-lang/rust#118212. This issue contains two examples with different causes of ICE: - The cause of the [first one](rust-lang/rust#150152 (comment)) is incorrect determination of whether we are in a trait impl [here](https://github.com/rust-lang/rust/blob/c4aa646f15e40bd3e64ddb5017b7b89b3646ac99/compiler/rustc_resolve/src/late.rs#L3553), we were using `trait_id.is_some()` which in case of an unresolved trait was `None`, we should have used `of_trait` from AST level for this purpose - The cause of the [second example](rust-lang/rust#150152 (comment)) is that with recursive delegations we started to provide DefIds of the root function of the delegation for recursive delegations instead of actual delegee id. This situation is described in comments in `DelegationIds` struct, now we provide different DefIds (either immediate delegee DefId or the root function DefId in `lower_delegation` method Moreover, this PR fixes how attributes inheritance work with recursive delegations, earlier we would have copied attributes from the root function, however now we inherit attributes from the actual delegee, for this purpose we store attributes to inherit for delegations too, in the same way they were stored for functions. r? `@petrochenkov`
stdarch subtree update Subtree update of `stdarch` to rust-lang/stdarch@6111906. Created using https://github.com/rust-lang/josh-sync. r? `@sayantn` My first josh sync, it lgtm, but let me know if I missed something. I'm especially looking forward to the amd GPU module, which we want to use for the offload project.
…e-numbers, r=yotamofek Fix copy code example with line numbers Fixes rust-lang/rust#150339. Since the line numbers are now included in the actual highlighted code, we need to filter them out when we "copy" the code. r? `@yotamofek`
JumpThreading: compute place and value indices on-demand Profiling JumpThreading reveals that a large part of the runtime happens constructing the place and value `Map`. This is unfortunate, as jump-threading may end up not even doing anything. The cause for this large up-front cost is following: `Map` attempts to create a `PlaceIndex` for each place that *may* hold a relevant value. This means all places that appear in MIR, but also all places whose value is accessed by a projection of a copy of a larger place. This PR refactors the creation of `Map` to happen on-demand: place and value indices are created when threading computation happens. The up-front mode is still relevant for DataflowConstProp, so is not touched.
…Simulacrum Add `MaybeDangling` to `core` This is the library part of adding `MaybeDangling`. Note that it doesn't actually do anything described in its docs (yet), I'll make a separate PR for that. Tracking issue: rust-lang/rust#118166. r? libs cc `@RalfJung`

…index, r=Mark-Simulacrum Fix `LinkedList::CursorMut::pop_front` to correctly update index When `pop_front` was called while the cursor pointed to the front element, `move_next` incremented the index but it was never decremented afterwards, causing the index to incorrectly report 1 instead of 0. Always decrement the index after popping from front using `saturating_sub` to handle edge cases safely. Fixes rust-lang/rust#147616
