For RVV, we prefer ’len' in elements which perfectly match our RVV instruction ISA define.
For example, for our indexed load:
vsetvli ...len = 4
vluxei v0, (a5), v2, v0.t
In this situation, vluxei will gather load 4 elements, and each element addresses are:
element 0 address = a5 + v2[0]
element 1 address = a5 + v2[1]
element 2 address = a5 + v2[2]
element 3 address = a5 + v2[3]
I am not sure why you mention 'len' in bytes.
Thanks.

I see this doesn't add a BIAS argument - I think we should be consistent
here, at least for the memory access internal functions. I'll note
that 'len' has issues with scatter/gather anyway since the trick of
handling 'len' in bytes by only providing QImode variants doesn't work
here. So maybe that's good enough for an argument to not add bias
either ...
Richard, do you have any opinion here?

Can you add internal_fn_len_index please and make use of it?
Should have asked for this in the previous patch already I guess.
Otherwise this looks good to me.
Thanks,
Richard.

Hi, Richi. I have added "BIAS" and send V4:
https://gcc.gnu.org/pipermail/gcc-patches/2023-June/623293.html
Forget about V3. I made a mistake there, sorry about that.
Thanks.

I see this doesn't add a BIAS argument - I think we should be consistent
here, at least for the memory access internal functions. I'll note
that 'len' has issues with scatter/gather anyway since the trick of
handling 'len' in bytes by only providing QImode variants doesn't work
here. So maybe that's good enough for an argument to not add bias
