Surface rust never calls this function, so it's not really meaningful to mark it unsafe.

[kkysen]

It doesn't matter if this is called normally or not. It's unsound to mark this as safe. Seems like it passes all of the tests marked unsafe, so that seems fine.

[fw-immunant]

My point is that there is no calling unsafe block that would place the other half (caller-side) of the SAFETY comment here, as calls to this function are inserted by safe code that modifies MIR regardless of this function's unsafety. If our MIR transformations are incorrect, the object program may exhibit UB; we're operating past Rust's safety boundary here.
