Proof step 5 from proof addbar-okarray-03 (previous step)

¬ (i = n→i(# ints) ∧ r ≠ jvmref) ⊦ r = jvmref, okarray(refval(r), byte_type, i, addbytearray(r, ints, st)) ↔ i = n→i(# ints)

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 4:
okarray(refval(r), byte_type, (addbytearray(r, ints, st)[r -- _length]) .intval, addbytearray(r, ints, st)) ⊦ (addbytearray(r, ints, st)[r -- _length]) .intval = n→i(# ints), r = jvmref

Rule argument

[emptyarg]
