Description
It is documented what the semantics are of basic arithmetic when overflow-checks is turned on: https://doc.rust-lang.org/reference/expressions/operator-expr.html#overflow.
However as far as I can see it is nowhere actually specified what arithmetic is supposed to do when overflow-checks is turned off, or whether this is subject to change, hardware specifics, etc.

Research direction
Start with the Rust Reference's expressions/operator-expr.html#overflow section and review how it documents arithmetic with overflow-checks enabled. Investigate the missing behavior when checks are disabled, including whether it is stable or hardware-specific. Done means the Reference clearly specifies the disabled-check semantics and their stability or platform limitations.
