Oh, reading about ASXD and 256-bit vectors makes me wonder if it would be better to plan
ahead and have a function, or DisasContext member, for the length of the vector.
like arm:
/* Return the byte size of the "whole" vector register, VL / 8. */
static inline int vec_full_reg_size(DisasContext *s)
{
return s->vl;
}
What I'm confused about is what is the difference between s->vl and s->vec_len ?
The first is for aarch64 SVE.
The second is for armv5 VFP (which was removed from armv8).
