RustIntrinsic

RustCall

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.

RiscvInterruptS
