首先说明一下 pc：程序寄存器，保留下一条CPU即将执行的指令 lr: 连接返回寄存器，保留函数返回后，下一条应执行的指令 PUSH {r4-r7,lr} 的确如你所说保存r4,r5,r6,r7,lr 的值到内存的栈中，那么最后当执行完某操作后，你想返回到lr指向的地方执行，当然要给pc了，因为pc保留下一条CPU即将...
说明:Ri为一个寄存器,可以是R0、R1、R2、R3、R4、R5、R6或R7。 3. push dataadr:将dataadr地址中的数据压入栈中。 格式:PUSH dataadr 说明:dataadr为一个数据地址,可以是一个立即数、寄存器地址或内存地址。 4. push codeadr:将codeadr地址中的数据压入栈中。 格式:PUSH codeadr 说明:codeadr为一个代码...
图8显示树莓派的ARM寄存器值及RAM堆栈区的内容 从图8可知,程序执行到第9行断点处时,sp=0x7efff150,r4=0x100,r5=0xff,r6=0x1234,r7=0xa0be。 下面输入s单步命令接着执行第9行的stmfd入栈指令(见图9)。图9 显示执行stmfd入栈指令后的树莓派ARM寄存器值及RAM堆栈区的内容 在图9中,再次...
