FYI, it occurred to me that some corner cases might not be quite right
with regards to alignment for the STRD instruction. It seems that the
hardware on which I tested it (Marvell Dove CPU) apparently copes with
misaligned SDRD's when they're still 32-bit aligned. So I need to run
this code through a real validation harness on different hardware.
