Ok,
e.g
#define SETANYEQZ(NAME, MO)                                  \
void HELPER(NAME)(CPULoongArchState *env, uint32_t cd, uint32_t vj) \
{                                                                 \
     int i;                                                                \
     bool ret = false; \
     VReg *Vj = &(env->fpr[vj].vreg); \
\
     ret = do_match2(0, (uint64_t)Vj->D(0), (uint64_t)Vj->D(1), 
MO);              \
     env->cf[cd & 0x7] = ret;      \
}
SETANYEQZ(vsetanyeqz_b, MO_8)
SETANYEQZ(vsetanyeqz_h, MO_16)
SETANYEQZ(vsetanyeqz_w, MO_32)
SETANYEQZ(vsetanyeqz_d, MO_64)

and
vsetanyeqz.b    $fcc5  $vr11
   v11    : {edc0004d576eef5b, ec03ec0fec03ea47}
------------------
do_match2
bits is 8
m1 is ec03ec0fec03ea47
m0 is edc0004d576eef5b
ones is 1010101
sings is 80808080
cmp1 is 0
cmp0 is edc0004d576eef5b
cmp1 is ec03ec0fec03ea47
cmp0 is 10000
cmp1 is 3000100
ret is 0

but,  the results is not correct  for vsetanyeqz.b. :-)

Thanks.
