Invalid instruction when emulation arm version libcrypto.so.1.1

[HclX]

*Describe the bug

Emulation fails with the following message:

[x]     Hexdump:
[x]     00 0e a0 f2 1e ff 2f e1
[x]     Disassembly:
[x]     PC = 0x9026b188

[x]     Memory map:

After checking this is inside of an arm version of libcrypto.so.1.1 file, here is the disassembled bytes in ghidra:

While Unicorn supports several CPUs of each architecture, Qiling does not specify which one it should use, so Unicorn picks up the default one. Most chances that this specific instruction (part of ARM Neon SIMD instructions) is not supported by that default CPU. We are planning on making that (choosing a specific CPU) a configurable setting.

Any idea to get around this issue before the feature is available?

Sorry for missing this for a long time..
The CPU selection feature has already been integrated into dev branch a while ago: see #1376
I am tentatively closing this, do not hesitate to re-open if the problem remains.
