Consider the program below, where M and N are (secret) #define'd constants:

int mat1[M][N];

int mat2[N][M];

int copy_element(int i, int j){

mat1[i][j]=mat2[j][i]

}

Here is the compiled assembly code for the above program:

copy_element:

pushq %rbp

movq %rsp, %rbp

movl %edi, -4(%rbp)

movl %esi, -8(%rbp)

movl -4(%rbp),%eax

movl -8(%rbp), %edx

movslq %edx, %rdx

salq $3, %rdx

addq %rdx, %rax

movl mat2(,%rax,4), %ecx

movl -8(%rbp), %eax

movslq %eax, %rdx

movq %rdx, %rax

addq %rax, %rax

addq %rdx, %rax

salq $2, %rax

addq %rsi, %rax

movl %ecx, mat1(,%rax,4)

popq %rbp

ret

Based on your understanding of C array representation, and the manner in which indices i and j are used, what are the values of M and N?
