REMAP is an advanced form of Vector "Structure Packing" that provides
hardware-level support for commonly-used *nested* loop patterns that would
otherwise require full inline loop unrolling. For more general reordering
-an Indexed REMAP mode is available (an abstracted analog to `xxperm`).
+an Indexed REMAP mode is available (a RISC-paradigm
+abstracted analog to `xxperm`).
REMAP allows the usual sequential vector loop `0..VL-1` to be "reshaped"
(re-mapped) from a linear form to a 2D or 3D transposed form, or "offset"
