1. For each instruction, give the 80x86 opcode and total number
of bytes of object code, including prefix bytes. Assume you are
in 64-bit mode and that
word0p, dbl0p
, and
quad0p
reference a
word, doub
leword and
quadword
in data, respectively.
Add ax, word0p
Sub dbl0p, ebx
Sub rax, 10
Add quad0p, 1000
Inc r10b
Dec word0p
Neg rdx
Inc QWORD PTR [rdx]

Mov ebp, esp ;
Push ebx ;
6. Please provide code for the following scenario:
Create a while loop that that checks for 4 iteractions
