--- Comment #7 from Jeffrey A. Law <law at redhat dot com> --- If you're V_C_E-ing to a narrower type, you just ignore the bits outside the target type, it's a lot like a narrowing subreg in the RTL world. I don't know what the semantics are for the widening case. ISTM that it's not really helpful there. At least that's my understanding after discussing pr80635 with Richi.
