// On non-Linux ARM, the 64-bit functions use instructions unavailable before the ARMv6k core.
// On ARM, x86-32, and 32-bit MIPS, it is the caller's responsibility
// to arrange for 64-bit alignment of 64-bit words accessed atomically.
// The first word in a variable or in an allocated struct, array, or slice can be relied upon to be 64-bit aligned.
