But still, I thought we had value range propagation rules to avoid
this sort of nonsense when possible (such as the example above)?
VRP doesn't help when the code doesn't have compile-time known values,
such as in the non-reduced code my example snippet was reduced from.
Right, it wouldn't always get rid of the message, but I would think it
should when it's known the value cannot be -128, such as the specific
example you posted.
