parasoft c test – 编译内联汇编代码

源代码 ：

#include <stdio.h>
void example()   { int arg1,arg2,add,sub,mul,quo,rem ;

 printf( "Enter two integer numbers : " );
 scanf( "%d%d",&arg1,&arg2 );


 __asm__ ( "addl %%ebx,%%eax;" : "=a" (add) : "a" (arg1),"b" (arg2) );
 __asm__ ( "subl %%ebx,%%eax;" : "=a" (sub) : "a" (arg1),"b" (arg2) );
 __asm__ ( "imull %%ebx,%%eax;" : "=a" (mul) : "a" (arg1),"b" (arg2) );

 __asm__ ( "movl $0x0,%%edx;"
           "movl %2,%%eax;"
           "movl %3,%%ebx;"
            "idivl %%ebx;" : "=a" (quo),"=d" (rem) : "g" (arg1),"g" (arg2) );

 printf( "%d + %d = %dn",arg1,add );
 printf( "%d - %d = %dn",sub );
 printf( "%d * %d = %dn",mul );
 printf( "%d / %d = %dn",quo );
 printf( "%d %% %d = %dn",rem );


 }

代码有错误.每个单词的错误是：

The word 'ebx' is not correctly spelled.

我该怎么办 ？
