Re: [PATCH 03/12] target/riscv: handle vadd.vx form mask and source overlap

[Max Chou]

Hi Anton,

I think that the commit message could be improved for better clarity.
The vext_check_ss function affects more RVV instructions than the 
vadd.vx instruction alone.
(PS:perhaps using the category (OPIVX/OPFVF/etc.) to describe the 
affected RVV instructions would be more helpful.)
Additionally, the patch 04/07/08/09/10 also have the same issue.
Thanks,
Max
