Proof step 18 from proof addarrays-out (previous step)

n→i(# refs) = countrefs(i0 ' + ints0), posints(ints0), 0 ≤ i0 ⊦ (addmultiarrays(refs, i0, [], mktype_from_dims(ty, countdims(i0 ' + ints0, i)), getdims(i0 ' + ints0), st)[_out]) = st[_out], mkfs(`java.lang.Object' .class, void_type, `out' .field) ' = _length, mkfs(`java.lang.Object' .class, void_type, `out' .field) ' = _type, ¬ getdims(i0 ' + ints0) .first < i0 ∧ ¬ 0 ∈ getdims(i0 ' + ints0) .butlast ∧ # refs = i→n(countrefs(i0 ' + getdims(i0 ' + ints0) .rest))

Heuristic elimination applied rule insert elim lemma

And obtained the following new goals

Proof step 7:
⊦ getdims(ints) = [] ↔ ints = []
Proof step 17:
getdims(i0 ' + ints0) = i1 + ints ∧ getdims(i0 ' + ints0) ≠ [], n→i(# refs) = countrefs(i0 ' + ints0), posints(ints0), 0 ≤ i0 ⊦ (addmultiarrays(refs, i0, [], mktype_from_dims(ty, countdims(i0 ' + ints0, i)), getdims(i0 ' + ints0), st)[_out]) = st[_out], mkfs(`java.lang.Object' .class, void_type, `out' .field) ' = _length, mkfs(`java.lang.Object' .class, void_type, `out' .field) ' = _type, ¬ i1 < i0 ∧ ¬ 0 ∈ getdims(i0 ' + ints0) .butlast ∧ # refs = i→n(countrefs(i0 ' + ints))
