Question

r1 ← r2 − r3
M[r1 + 100] ← r2

how many RBW AND WBW DEPENDENCY???

Comments

I think there is RAW dependency because of r1 as you need to read r1+100 after its write. I don't see WAW dependency as no same 2 registers are getting written only r1 is written and then we are storing value of r2 in some memory location.

Here RAW Dependency only because after writing Read operation should be performed
