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.

Remove custom frame info registration on i686-pc-windows-gnu

2022-08-23T08:12:58+00:00

The indirection is no longer needed since we always link to libgcc even when the panic_abort runtime is used. Instead we can just call the libgcc functions directly.

Bump bootstrap compiler to 1.50 beta

Rename `optin_builtin_traits` to `auto_traits`

2020-11-23T22:14:06+00:00

They were originally called "opt-in, built-in traits" (OIBITs), but people realized that the name was too confusing and a mouthful, and so they were renamed to just "auto traits". The feature flag's name wasn't updated, though, so that's what this PR does. There are some other spots in the compiler that still refer to OIBITs, but I don't think changing those now is worth it since they are internal and not particularly relevant to this PR. Also see .
