In general, I want to keep existing stubs working. But someone who
has access to an affected stub needs to lend a hand here; I don't and
can't test anything.
With stubs out there sending both FPA-regs+fake-CPSR and
FPA-regs+XPSR, I don't know how to make it work; in fact, I don't know
how FPA-regs+XPSR ever worked.
