armv7/8-A simulator port

[faisal]

I've been making use of the simulator port quite a bit, and now need to be able to run simulation on something like a raspberry pi.

The current simulation port is for x86. Any hope you can make a port for armv7-A and armv8-A (I think they may be identical?).

Hi,

I don't have ARM Linux hosts but ARMv7a should be simple, ARMv8a I have no idea frankly, never touched that.

Anyway the only asm code required is the switch routine: push all function-saved registers, switch stack, pop all function-saved registers, the rest of simulator files would be exactly the same.

In case of ARMv7a it could be the very same simulator port with an #ifdef around the switch code.
