  The radix 2^51 trick

          To do long addition we sum right to left, if result is greater than 10, we carry 1 to its left.
  

  The assembly code have extra instruction to hold that carry, if we can eliminate it, then our generated assembly code has less thing to do. How can we do that?

  Now that we know how to read assembly language, we can talk about how parameter passing works at the machine level and its consequences for writing faster code. We will focus on x86_64, but ARM64 works in a roughly similar way.What does “parameter passing” mean?Let’s say you’ve written a large program, and in it you...
