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, mf4, mf2, m1, m2, m3, m4
.endm
This can be addressed with another patch set.
