Understanding Base Pointer and Stack Pointers: In Context with gcc Output

Question

I have the following C program:

int main()
{
    int c[10] = {0, 0, 0, 0, 0, 0, 0, 0, 1, 2};
    return c[0];
}

and when compiled using the -S

Answer 1

Keep in mind that on x86 the stack grows downward. Pushing onto the stack will subtract from the stack pointer.

%rbp <-- Highest memory address
-12
-16
-20
-24
-28
-32
-36
-40
-44
-48  <-- Address of array
