library/compiler: add `PointeeSized` bounds

2025-06-16T23:04:33+00:00

As core uses an extern type (`ptr::VTable`), the default `?Sized` to `MetaSized` migration isn't sufficient, and some code that previously accepted `VTable` needs relaxed to continue to accept extern types. Similarly, the compiler uses many extern types in `rustc_codegen_llvm` and in the `rustc_middle::ty::List` implementation (`OpaqueListContents`) some bounds must be relaxed to continue to accept these types. Unfortunately, due to the current inability to relax `Deref::Target`, some of the bounds in the standard library are forced to be stricter than they ideally would be.

Rename `cfg_match!` to `cfg_select!`

2025-05-20T21:16:23+00:00

At [1] it was pointed out that `cfg_match!` syntax does not actually align well with match syntax, which is a possible source of confusion. The comment points out that usage is instead more similar to ecosystem `select!` macros. Rename `cfg_match!` to `cfg_select!` to match this.

Convert `ShardedHashMap` to use `hashbrown::HashTable`

2025-03-11T00:08:30+00:00

The `hash_raw_entry` feature has finished fcp-close, so the compiler should stop using it to allow its removal. Several `Sharded` maps were using raw entries to avoid re-hashing between shard and map lookup, and we can do that with `hashbrown::HashTable` instead.
