Also as explained in [[sv/mv.swizzle]], [[sv/mv.vec]] and the [[svp64/appendix]], Pack and Unpack Mode bits can extend down into Sub-vector elements to influence vec2/vec3/vec4 -sequential reordering, but even here, REMAP is not *individually* +sequential reordering, but even here, REMAP reordering is not *individually* extended down to the actual sub-vector elements themselves. +This keeps the relevant Predicate Mask bit applicable to the Subvector +group, just as it does when REMAP is not active. In its general form, REMAP is quite expensive to set up, and on some implementations may introduce latency, so should realistically be used -- 2.30.2
