I can't find the official docs, but this page
http://www.ibiblio.org/gferg/ldp/GCC-Inline-Assembly-HOWTO.html says:

"A" : Specifies the `a’ or `d’ registers. This is primarily useful for 64-bit
integer values intended to be returned with the `d’ register holding the most
significant bits and the `a’ register holding the least significant bits.
