Proof step 57 from proof hasSharing-put-byteval (conclusion)

⊦ ¬ junkref(str, r, st) ∧ 0 ≤ i ∧ i < st[r1 -- _length] .intval ∧ okarray(r1, byte_type, st) → (¬ hasSharing(r, st[r1 -- i ', byteval(by)]) ↔ ¬ hasSharing(r, st))

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 56:
i < st[r1 -- _length] .intval, okarray(r1, byte_type, st), 0 ≤ i, 0 < st[r1 -- _length] .intval, r1 ∈ st ⊦ ¬ hasSharing(r, st[r1 -- i ', byteval(by)]) ↔ ¬ hasSharing(r, st), r1 = jvmref, junkref(str, r, st)
