Consider the source code below, where M and N are constants declared with #define.

int array1[M][N];

int array2[N][M];

int copy(int i, int j)

{

array1[i][j] = array2[j][i];

} Suppose the above code generates the following assembly code: copy:

pushl %ebp

movl %esp,%ebp

pushl %ebx

movl 8(%ebp),%ecx

movl 12(%ebp),%ebx

leal (%ecx,%ecx,8),%edx

sall $2,%edx

movl %ebx,%eax

sall $4,%eax

subl %ebx,%eax

sall $2,%eax

movl array2(%eax,%ecx,4),%eax

movl %eax,array1(%edx,%ebx,4)

popl %ebx

movl %ebp,%esp

popl %ebp

ret
