Proof step 6 from proof compatarray-abstract (previous step)

st[r -- _length] = intval(i), st[r -- _type] .type = mkarraytype(abstract_type), 0 < i, r ∈ st, is_integervalue(st[r -- _length]), r -- _length ∈ st, is_arrayref(r, i, st), ∀ j. ¬ j < 0 ∧ ¬ i ≤ j → compat(str, st[r -- j '], abstract_type, st) ⊦ i = 0, r = jvmref

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 5:
st[r -- _type] .type = mkarraytype(abstract_type), st[r -- _length] = intval(i), 0 < i, is_arrayref(r, i, st), r -- _length ∈ st, r ∈ st, ∀ j. ¬ j < 0 ∧ ¬ i ≤ j → compat(str, st[r -- j '], abstract_type, st) ⊦ r = jvmref, i = 0
