Question about using `__riscv_vlm_v`

[zhongjuzhe]

Compiler is not able to access bit-represent address (Address should be byte orient).

Here, for VLEN = 128bit, each mask you are using for e32m1 here is 4bits,
so you end up with accessing bit field memory.

If you specify SPIKE --varch=vlen:256, your program will work correctly since when for VLEN = 256, each e32m1 mask is 8bit (1byte).

If you want to run on VLEN = 128, I suggest you revise the code as follows:

I understand the RVV mask is quite confusing but I didn't have an immediate solution for that.
