9. The following code cod for a c procedure: e sequence occurs near the beginning of the assembly code generated by Ecc 5 Points 1. subq 2, movq 3. movq 4. movq 5. movq 6" movq 7, movq 8.movq 9.movq 10, movq $24, %rsp %rbx ,(%rsp) %r12, 8(%rsp) %r13 , 16(%rsp) 16(%rbp), %rbx 24 (%rbp), %r13 (%rbx), %r12 (%r13), %rax 16(%rbp ) ,%rdx (%rax), %rcx program modifies these and others. At the end of the procedure, the values of the registers %rbx, %r12, and %r13 are restored (those instructions are not shown) while the other registers are left in their modified states. Why are not all of the registers saved and restored? we see that just three registers (%rbx, %r12 and %r13) are saved on the stack in lines 2-4. The
