--- Comment #9 from Robin Dapp <rdapp at gcc dot gnu.org> ---
We already merge with operand[0], just the TU is missing as far as I can tell.
I'm seeing the following output with my patch:
vsetivli zero,8,e16,mf4,tu,ma
vle16.v v1,0(a1)
vmv.s.x v1,a2
vse16.v v1,0(a0)
That should still be ok because vmv.s.x always only updates the first element
regardless of vl and the rest of the vsets can be fused?
I'm currently on another problem but will get back to this.
