Ouch. 24 of 64 wasted bytes for 64-bit? I wonder if there's a better way we can encode this to avoid 3 copies of the virtual address for read/write/code. Or if we're better off using more than one insn to multiply by a non-power-of-two. Or if the hardware multiplier is fast enough just multiply by the proper constant. r~
