What you do want is compiled code that can trap on overflow and avoid
trapping on overflow without code substitution or being re-compiled.
This way production code can avoid trapping but if the debugger is
turned on, you can trap.

Both architectures got this one wrong--IMO--and so does RISC-V.

Architectures without overflow traps are notorious for excess instruction

Granted, Optimization can do a lot of strange code emission and movement
when one does not care about precise overflow semantics. But, as a whole,
we are a society where we want high HP automobiles more than we want safe
automobiles ('we' not including *.gov's).

It is much harder than that. For example: does a signed shift left
overflow when significant bits are shifted out ?? What if the sub-
sequent instruction shifts the result back and the pair are acting
as a bit-field extract ?? My 66000 has bit field extracts for exactly
this reason. Floating-point has a lot of these cases, too.
