state. If `SVi=0, Rc=0, vf=0` this instruction is a `nop`.
When `SVi` is 1-4 the REMAP Schedule for a given SVSHAPE may be
To obtain the full set of possible computed element
indices use `svstep RT.v,SVI,1` which will store all computed element
indices, starting from RT. If Rc=1 then a co-result Vector of CR Fields

loops when either Matrix Mode or DCT/FFT is set. In other words,
for example, when the `xdim` inner loop reaches the end and on the next
iteration it will begin again at zero, the CR Field `EQ` will be set.
+With a maximum of three loops within both Matrix and DCT/FFT Modes,
+the CR Field's EQ bit will be set at the end of the first inner loop,
+the LE bit for the second, the GT bit for the outermost loop and the
+SO bit set on the very last element, when all loops reach their maximum
