Proof step 25 from proof isarray-put (previous step)

st[r -- _type] = typeval(mkarraytype(ty0)), r ∈ st, okval(val, ty), okarray(r, ty0, st), r -- _type ∈ st ⊦ r = jvmref, ty = void_type, mkfs(class, ty, fieldvar) ' = _length, okarray(r, ty0, st[r1 -- mkfs(class, ty, fieldvar) ', val])

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 5:
⊦ r ≠ r1 → (okarray(r, ty, st[r1 -- sk, val]) ↔ okarray(r, ty, st))
Proof step 24:
¬ r ≠ r1, st[r -- _type] = typeval(mkarraytype(ty0)), r ∈ st, okval(val, ty), okarray(r, ty0, st), r -- _type ∈ st ⊦ r = jvmref, ty = void_type, mkfs(class, ty, fieldvar) ' = _length, okarray(r, ty0, st[r1 -- mkfs(class, ty, fieldvar) ', val])

Rule argument

[crewrite-arg: okarray-put-other , F , [val, sk, r1, st, ty, r] → [val, mkfs(class, ty, fieldvar) ', r1, st, ty0, r] ]
