Virgil has a family of completely well-defined (i.e. no UB) fixed-size integer types with some hard-fought rules that I eventually got around to documenting here:
https://github.com/titzer/virgil/blob/master/doc/tutorial/Fi...
One of the key things is that values are never silently truncated (other than 2's-complement wrap-around) or values changed; only promotions. The only sane semantics for over-shifts (shifts larger than the size of the type) is to shift the bits out, like a window.
The upshot of all that is that Virgil has a pretty sane semantics for fixed-size integers, IMHO.
