Hi, Richi.
For GATHER_LOAD which doesn't have len and mask.
Should I keep it as gather_load, then I support both gather_load and
len_mask_gather_load ?
Or I should normalize it into len_mask_gather_load with length = vf and mask =
{1,1,1,1,1,...}, then
I only need to support len_mask_gather_load in RISC-V port?
Thanks.

No, please adjust the gather pattern recognition to produce either
appropriate LEN_ variant IFNs or simply keep only the unconditional
and conditional mask variants from patterns but code generate
the len_ variants. I don't really see what the problem is.
Maybe you fail to specify the appropriate ifn when you inspect
the scalar internal fn call?
