I think it would be more interesting and fair if he hand-wrote the assembly code as well as the LLVM code. Those labels are unnecessarily intimidating and I'm sure a human could make the code structure much more clear.

  $ cat >hello.s <<EOF
  .text
  .globl main
  main:
  	leaq msg, %rdi
  	callq puts
  	ret

  .data
  msg:	.asciz "hello world\n"
  
  EOF
  $ as -o hello.o hello.s; cc -o hello hello.o; ./hello
  hello world

I'd love for this post to be a little more detailed, actually.
