GC Roots misunderstanding?

I know Roots:

  • static fields
  • method parameters
  • local fielfs
  • f-queue, which also contains a pointer to objects to be completed.
  • cpu register <= ???

enter image description here

Now let's talk about registers.

the code that they may contain looks like:

mov bx, 0034h   ; bx = 52 (stored in 16 bits)
mov cl, bl      ; cl = lower 8-bits of bx
mov eax, ecx
call print_int

but wait !

If im not mistaken, this is really a code that Holding those static, localand parameters- the first time!

So why write this TWICE ? (or from another direction?)

Why write (for example)

  Foo f = new Foo();

**and also** 

mov bx, 0034h   //<-------- represents the `f` address or something like that

change

my register question comes from here: enter image description here
