Sorry, the previous logic was indeed a bit confusing. I rewrote it,
renaming the third parameter to max_lmul.
If e16 is involved in the function, then vsetvlstatic8 uses max_lmul == m4.
If e32 is involved in the function, then vsetvlstatic8 uses max_lmul == m2.
If e16 is involved in the functio

1/4 of vlen? Do you mean limit to EMUL=1 for EEW=32 and EMUL=1/4 for EEW=8?
Limiting LMUL to less than 1 at maximum EEW is useless from a f
I reviewed it again, the purpose of is_w is to limit lmul to a maximum of
1/4 of vlen, to prevent vector register shortage, which can also be
considered as vset limiting lmul. I renamed it to quarter_len_limit.
t0 is changed to t1.

It is a special case added to merge the vset of avg and w_avg, how about
giving it a default value so that it doesn't affect the use of other
functions?
