ASSIGNMENT

• Copy and paste the code below to https://godbolt.org
• Use the following compiler for the ASM code generation: <strong>x86-64 clang 10.0.0</strong>
• Under the compiler options, use -Os
• Create a separate text file or markdown (MD) file to explain the x86 registers being used in the assembly
  • Example: RBP, RSP, EAX, EDI (you will need to research, but with Google, you will be okay)
• Create a separate text file or markdown (MD) file:
  • Explain each and every single line of the ASM program
  • You do not have to explain the C code
  • Attempt to provide the WHY rather than the WHAT
  • For example, do not just say “Moving R1 to R0” but state that “Moving R1 to R0 such that we can pass that as the first parameter to printf”

  #include <stdio.h>
  #include <stdlib.h>
  
  __attribute__((noinline))
  int sum2(int a, int b) {
      return a + b;
  }
  
  __attribute__((noinline))
  void print_the_value(int value) {
      printf("%d", value);
  }
  
  void entry_point() {
      int a = rand(); // R4
      int b = rand(); // R0
      int result = sum2(b, a);
      print_the_value(result);

  }
