为什么地址登记后加(A0)+
原标题:Why address register postincrement is (A0)+

基本上使用68000的组装语言,以张贴地址登记簿:

(A0)+

示例示例示例示例

MOVE (A0)+,D0

这将移动到 D0 的值, 以 A0 的地址表示, 1 还会递增 A0

考虑到(A0) A0 指指的值,如果后加分语法是:

(A0+)

或者我错过了什么?

最佳回答
MOVE.L (A1)+,D0 ; increments A1 by 4, because it is long operation
                ; and 4 is size of long

I think that current postincrement syntax points at this feature, while (A1+) more suggests that A1 incremens by one always.
