Answer:
Following are attached images that will help you understand the complete code. The code is tested with different variables and different outputs are obtained. All the necessary description is given in the form o comments inside the code.
Explanation:
Using programming knowledge, it is possible to use programming logic, we can differentiate and find the terms
<h3>Writing the code and understanding the programming logic:</h3><em>.data</em>
<em>sourceword:</em>
<em>.word 0xAB</em>
<em>wordmask:</em>
<em>.word 0xCF</em>
<em>operand:</em>
<em>.long 0xAA</em>
<em>.text</em>
<em>.globl _start</em>
<em>_start:</em>
<em>movw sourceword, %ax # ax=0x00AB ( move the word value of sourceword =0x00AB to ax register.)</em>
<em>movw %ax, %bx # bx=0x00AB ( copy the value of ax to bx register.)</em>
<em>xorw %cx, %cx # cx=0000 ( cx=cx XOR cx, that is clear cx register.)</em>
<em />
<em>andw wordmask, %ax # ax=0x008B ( ax=ax AND wordmask= 0x00AB AND 0x00CF= 0x008B)</em>
<em>orw wordmask, %bx # bx=0x00EF (bx=bx OR wordmask= 0x00AB OR 0x00CF= 0x00EF.)</em>
<em>xorw wordmask, %cx # cx=0x00CF (cx=cx XOR wordmask= 0x0000 XOR 0x00CF=0x00CF.)</em>
<em />
<em>movl operand, %eax # eax=0x000000AA. ( copy the 32-bit value of operand=0x000000AA to eax.)</em>
<em>movl %eax, %ebx # ebx=0x000000AA.( copy the value of eax to ebx.)</em>
<em>movl %eax, %ecx # ecx=0x000000AA. ( copy the value of eax to ecx.)</em>
<em />
<em>shll $3,%eax # eax=0x00000550. ( logical shift left of eax=0x000000AA by 3 bits.)</em>
<em />
<em># 0x000000AA=00000000000000000000000010101010</em>
<em />
<em># =>00000000000000000000010101010000=0x00000550.</em>
<em />
<em>rorl $4,%ebx # ebx=0xA000000A. (Rotate right ebx=0x000000AA by 4 bits.)</em>
<em />
<em># 0x000000AA=00000000000000000000000010101010</em>
<em />
<em>3 =>10100000000000000000000000001010= 0xA000000A.</em>
<em />
<em>sarl %ecx # here the count value to shift the bits not mentioned.</em>
<em />
<em># It is the arithmetic shift right instruction. the shifted left bits filled with MSB bit.</em>
