AArch32 execution mode switch

[ledstobstec]

I'm trying to emulate a 32-bit ARM binary that makes use of the ARMv8 Crypto Extensions. From what I understand, the only way to access these extensions is by starting in AArch64 mode and then switching to AArch32. Is it possible to do this in Unicorn? If so, how can it be done?

Switching mode is possible but I'm not sure if the extension is implemented by QEMU.
