Unadjusted
Not a stable ABI, just directly use the Rust types to describe the ABI for LLVM. Even normally ABI-compatible Rust types can become ABI-incompatible with this ABI!
RustCold
For things unlikely to be called, where reducing register pressure in
extern "Rust"
callers is worth paying extra cost in the callee.
Stronger than just #[cold]
because fn
pointers might be incompatible.

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...)
attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
