5.9.2 存储类指令
5.9.2.1 base – 显示或者设置地址偏移
=> help base
base
- print address offset for memory commands
base off
- set address offset for memory commands to 'off'
=>
你可以使用base命令(简写为ba)来显示或者设置一个“基地址”作为所有存储类命令的地址偏移值。默认的基址是0,所以你输入的所有地址都是实地址。但是,当你重复访问某一特定存储区域(如一些嵌入式PowerPc处理器的内存)时,如果设置此区域的开始地址作为基址,只需使用偏移地址,这将非常简便:
=> base
Base Address: 0x00000000
=> md 0 c
00000000: feffffff 00000000 7cbd2b78 7cdc3378 .........+x.3x
