Instead o backends to implement both the intrinsic and the MIR operation, the `lower_intrinsics` pass will convert the calls to the MIR operation. Backends do not need to know about these intrinsics at all. These intrinsics only make sense without a body, and can be declared as a `#[rustc_intrinsic]`. -The body is never used, as calls to the intrinsic do not exist anymore after MIR analyses. +The body is never used as the lowering pass implements support for all backends, so we never have to +use the fallback logic. ## Intrinsics without fallback logic |
