Proof step 13 from proof pathex-putbyteval-01 (conclusion)

⊦ okbytearray(r2, st) ∧ ¬ junkref(str, r, st) ∧ ¬ path∃(str, r, r1, st) → ¬ path∃(str, r, r1, st[r2 -- i ', byteval(by)])

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 12:
okbytearray(r2, st), path∃(str, r, r1, st[r2 -- i ', byteval(by)]) ⊦ junkref(str, r, st), path∃(str, r, r1, st)
