ASM编译问题 [英] asm compile issue

问题描述

:96: Error: `(%rax,%edx,4)' is not a valid base/index expression

:97: Error: `-4(%rax,%edx,4)' is not a valid base/index expression

101: Error: `(%rax,%edx,4)' is not a valid base/index expression

102: Error: `-4(%rax,%edx,4)' is not a valid base/index expression

我得到这些错误消息不知道如何解决它，这是我的code

i get these error messages not sure how to fix it this is my code

                 "movl        $0, %6\n"
     line96      "start:        \n\t"
     line97      "movl        (%1,%3,4),%4\n\t"       
                 "movl        -4(%1, %3, 4), %5\n\t"  
             "cmpl        %4, %5\n\t"    
    line 101     "jle             next\n\t"
     line102     xchgl        %4, %5\n\t"               
                 "movl        %4, (%1, %3, 4)\n\t"        
                 "movl        %5, -4(%1, %3, 4)\n\t"        
                 "movl        $1, %6\n\t"

...我的code是长，所以我没有要发布整个code，但我在做ASM冒泡排序,,我编译时出现上述错误信息不太清楚如何解决它......如果任何人能对什么是错，将有助于解释..感谢..对不起，如果格式是有点乱糟糟的是新来这个..

... my code is long so i did not want to post the whole code but i am doing a bubble sort in asm ,, when i compile i get the above error messages am not quite sure how to fix it ... if any one could explain to what is wrong will be helpful .. thanks .. sorry if the format is a bit untidy am new to this ..

推荐答案

您已经错误地使用间接寻址。

You've incorrectly use indirect addressing.

这是错误地使用斧头：DX对同排量基地指针。参阅这并的这个的例子。

It is incorrectly use ax:dx pair as base pointers with displacement. Refer to this and this for examples.
