I did see earlier that Github Action ran (In the 'Checks' tab) and finished,

```m``` will be updated in every iteration of this loop, so ```m``` is not a
loop-invariants actually.
I can see the assembly code of this

Thanks for your review.

In Vector API Java level, vector mask is represented as a boolean array with
0x00/0x01 (8 bits of each element) as values, aka in-memory format. When it is
loaded into vector register, e.g. Neon, the in-memory format will be converted
to in-register format with 0/-1 value for each lane (lane
