Proof step 4 from proof arrayComp-05 (previous step)

∀ j1. 0 ≤ j1 ∧ j1 < j + j0 → st[r1 -- (i1 + j1) '] = st[r2 -- (i2 + j1) '], 0 < j, 0 ≤ j0 ⊦ st[r1 -- (i1 + j0) '] .byteval = st[r2 -- (i2 + j0) '] .byteval

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 3:
0 < j, 0 ≤ j0, ∀ j1. ¬ j1 < 0 ∧ ¬ j + j0 ≤ j1 → st[r1 -- (i1 + j1) '] = st[r2 -- (i2 + j1) '] ⊦ st[r1 -- (i1 + j0) '] .byteval = st[r2 -- (i2 + j0) '] .byteval
