Added test coverage for reads to HPM counters and coverage exclusions
Created by: dherreravicioso
Hi all,
This PR contains coverage exclusions for:
- Misaligned instructions, as they are impossible in rv64gc
- MSTATUSH, as that register will only be used in 32-bit configurations
In addition, we added some tests to write to HPM counters from different privileged modes with different conditions of the SCOUNTEREN and MCOUNTEREN registers.
Thanks!
