Proof step 34 from proof isarray-put (conclusion)

⊦ is_array(r, st) ∧ oktype(val, ty, st) ∧ ty ≠ void_type ∧ mkfs(class, ty, fieldvar) ' ≠ _length → is_array(r, st[r1 -- mkfs(class, ty, fieldvar) ', val])

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 1:
⊦ oktype(val, ty, st) ↔ okval(val, ty)
Proof step 33:
is_array(r, st), okval(val, ty) ⊦ mkfs(class, ty, fieldvar) ' = _length, ty = void_type, is_array(r, st[r1 -- mkfs(class, ty, fieldvar) ', val])
