--- Comment #5 from java4ada at yahoo dot com ---
NEON instructions like vst/vld [:128] and [:256] need 16-byte and 32-byte
alignment, respectively.  Does it mean under ARM EABI both should be replaced
with [:64] ? (Probably only at the cost of 1-2 cycle anyway)

What other ARM ABI we can configure to get higher alignment than 8-byte?
