[Qemu-devel] why do qem/arm not clear CPU_INTERRUPT_HARD bit of env->interrupt_request automatically?

[Donald Liew]

i'm reading qemu-system-arm code and trying to add some more
evaluation boards support for it. in the 0.8.2 source code i found
something i can't understand, when handling interrupts all other
targets clears this bit after calling do_interrupt, however the arm
target doesn't do this, why? won't this cause problems like redundant
interrupts? any special consideration about this?
