What we could do is
prev.set_ratio (calculate_ratio (prev.get_sew (), prev.get_vlmul ()));
prev.set_vlmul (calculate_vlmul (prev.get_sew (), prev.get_ratio ()));
No, that also doesn't work because the ratio can be invalid then.
We fuse two vsetvls. One of them has a larger SEW which we use. Then
we either
- Keep the old ratio and calculate a new LMUL. That might lead to invalid
LMUL.
- Keep the old LMUL and calculate a new ratio. That might lead to an invalid
ratio.
I think the easiest way out is to copy the vsetvl with the larger SEW.
