WebNov 19, 2015 · Both of the operands to the multiplication must be of the same type. To that end, x is promoted to type __int128, because y is of this type after the cast, and the integer promotion rank of __int128 is higher than that of int64_t. One of the conversions is done by cqto, but that only works on rax, so the other is converted by sarq. –
