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. -- Daniel Jacobowitz CodeSourcery
