// See the above comment for Adjust::Deref

I thought the comment was misplaced. Why do we mention about Adjust::Deref in Adjust::Unsize?

Also, it does not seem like the existing "above comment" spoke about Adjust::Deref.

It's about the comment in line 94. This code exists solely to improve diagnostics. Maybe pull it out into a function instead of duplicating the logic?

You also need to update src/tests/mir-opt/storage_live_dead_in_statics.rs to mention Pointer(Unsize) instead of just Unsize

…casts-because-that-sounds-way-to-general-aaaa, r=oli-obk

Rename `adjustment::PointerCast` and variants using it to `PointerCoercion`

It makes it sounds like the `ExprKind` and `Rvalue` are supposed to represent all pointer related casts, when in reality their just used to share a little enum variants. Make it clear there these are only coercions and that people who see this and think "why are so many pointer related casts not in these variants" aren't insane.

This enum was added in rust-lang#59987. I'm not sure whether the variant sharing is actually worth it, but this at least makes it less confusing.
