ARM32 opcode_count returns always zero

Created by: bernhardklein

Hello together,

thank you for your engagement in the project. I'm new to this project and it is exiting. However I run into some trouble and maybe some of you can help me out.

When I run a command like: ./bin32/drrun -c api/bin/libopcode_count.so -opcode 36 -- ls I always get: 0/0 instructions executed executed on a arm device, a Raspberry Pi 3B or Pi4. I tried a lot of different opcodes it always looks the same. If I instead run it on a a x86 based machine I get plausible results.

Is the opcode_count sample not yet supported for arm devices? Or am I doing something wrong?

Thank you very much!

Best Regards Bernhard
