golang doc:
// BUG(rsc): On x86-32, the 64-bit functions use instructions unavailable before the Pentium MMX.
//
// 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.
