[PATCH 1/2] util/log: Add vu to dump content of vector unit |
Date: |
Fri, 8 Jul 2022 16:57:35 +0800 |
Add new option for -d vu to dump the content of vector unit, many target
has vector register, but there is no easy way to dump the content, we
use this on downstream for a while to help debug, and I feel that's
really useful, so I think it would be great to upstream that to save debug time
for other people :)
