Hi Yuechi,
The performance is good.
There are many similar .if blocks in vsetvlstatic8, vsetvlstatic16, and
vsetvlstatic32.
Could we define an intermediate macro, vsetvlstatic, and use it to
implement the above macros?
like:
.macro vsetvlstatic8 w, vlen
vsetvlstatic 8, w, vlen, mf8, m
Thank you, this approach can indeed address similar if else scenarios.
vsetvlstatic \w, \vlen, e8, mf8, mf4, mf2, m1, m2, m4
vsetvlstatic \w, \vlen, e16, mf4, mf2, m1, m2, m4, m8
vsetvlstatic \w, \vlen, e32, mf2, m1, m2, m4, m8, m8
I plan to submit it after this patch set gets merged.

Hi Andrea
I havnt really followed your gsoc work so in case some of my comments
below differs from your mentor(s), please point that out to me.
also maybe your mentors can do a full review (in CC) as it seems
noone else has reviewed your patch.
