--- Comment #4 from Wojciech Mula <wojciech_mula at poczta dot onet.pl> ---
Although, there's no word-wise set for equality, thus I think this sequence
would be better.
```
lbu a0, 1(a1)
lbu a2, 0(a1)
lbu a3, 2(a1)
lb a1, 3(a1)
xori a0, a0, 'z'
xori a2, a2, 'g'
xori a3, a3, 'i'
xori a1, a1, 'p'
or a0, a0, a2
or a1, a1, a3
or a0, a0, a1
seqz a0, a0
```
