示例1:

{
CPUClass *cc = CPU_GET_CLASS(cs);
ARMCPU *cpu = ARM_CPU(cs);
CPUARMState *env = &cpu->env;
bool ret = false;
if (interrupt_request & CPU_INTERRUPT_FIQ
&& !(env->daif & PSTATE_F)) {
cs->exception_index = EXCP_FIQ;
cc->do_interrupt(cs);
ret = true;
}
/* ARMv7-M interrupt return works by loading a magic value
* into the PC. On real hardware the load causes the
* return to occur. The qemu implementation performs the
* jump normally, then does the exception return when the
* CPU tries to execute code at the magic address.
* This will cause the magic PC value to be pushed to
* the stack if an interrupt occurred at the wrong time.
* We avoid this by disabling interrupts when
* pc contains a magic address.
