// Pseudo 256-bit registers to represent pairs of Q registers. These should

// These are used for NEON load / store instructions, e.g. vld4, vst3.

// starting D register number doesn't have to be multiple of 4. e.g.
// D1, D2, D3, D4 would be a legal quad. But that would make the sub-register
// stuffs very messy.
