Cosmetic detail: Use `unsigned int` to index triggers (as opposed to riscv_reg_t), which corresponds to the data type of `trigger_count` in `struct riscv_info_t`. Change-Id: I83539abdffa41aec2060fbd0c81496ab9607c9ea Signed-off-by: Jan Matyas <[email protected]>

There was a problem hiding this comment.
IMHO, it's better to use riscv_reg_t. Trigger index is the value of tselect. AFAIK, the spec allows for any number of triggers that should fit into tselect (up to 2^XLEN).
Current OpenOCD version limits the number of triggers, but this limit is completely arbitrary.

Thanks for your reply. I agree and I am closing this merge request. I have started looking at the data types more broadly with the hope that I have submitted first two merge requests on that topic already:
I plan to submit more related patches later. |
