Question: Use the following code fragment: Loop: I d x 1 , 0 ( x 2 ) ; load x 1 from address 0 + x

Use the following code fragment:
Loop: Idx1,0(x2); load x1 from address 0+x2
addi x1,x1,1,;x1=x1+1
sdx1,0(x2),; store x1at address 0+x2
addi x2,x2,4,;x2=x2+4
sub x4,x3,x2,;x4=x3-x2
bnez x4, Loop ; branch to loop ifx40
Assume that the initial value of x3 is 2+396.
Q1. List all data dependences in the code above: Record the register, source instruction, and
destination instruction. For example, there is a data dependency for register 1 from the ld to
the addi.
Hint: There are totally 6 data dependences.
Use the following code fragment: Loop: I d x 1 ,
