MadeEasy Test Series: Compiler Design - Static Single Assignment

Question

X = A / b

Y = C + D

Y = Y - X

X = D + Y

Z = F + Y

Z = Z + A

MInimum number of total variables needed to convert above TAC to Static Single Assignment

Answer given ==>11

My apporach

X1 = A / b

Y1 = C + D

Y2 = Y1 - X1

X2 = D + Y2

Z1 = F + Y2

Z2  = Z1 + A

Is above code in SSA ??

How can you say that b is not a variable ?

is it given in the question?

---

ok as you say

if you count 'b' as a variable the answer will be 11

else it will be 10.

I'll be counting 'b' as a variable as it isn't given in the question that b is a constant.

---

It will be 11 only ..ur right bro

...either b / B it is variable ...

Answer 1

11 is correct answer.
