Proof step 4:
⊦ is_array(str, r, st) ∧ st[r -- _type] .type ≤ ty → ( validrefs(str, r ' + refs, ty, st) ↔ refs = [] ∨ (∃ i. 0 ≤ i ∧ i < st[r -- _length] .intval ∧ is_referencevalue(st[r -- i ']) ∧ refs .first = st[r -- i '] .refval ∧ validrefs(str, refs, st[r -- _type] .type .type, st)))
Proof step 43:
is_array(str, r0, putByteArray(bytes, r, i, st)) ∧ (putByteArray(bytes, r, i, st)[r0 -- _type]) .type ≤ ty, st[r0 -- _type] .type ≤ ty, refs0 = [] ∨ (∃ i0. 0 ≤ i0 ∧ i0 < (putByteArray(bytes, r, i, st)[r0 -- _length]) .intval ∧ is_referencevalue(putByteArray(bytes, r, i, st)[r0 -- i0 ']) ∧ refs0 .first = (putByteArray(bytes, r, i, st)[r0 -- i0 ']) .refval ∧ validrefs(str, refs0, (putByteArray(bytes, r, i, st)[r0 -- _type]) .type .type, putByteArray(bytes, r, i, st))), okbytearray(r, st), is_array(str, r0, putByteArray(bytes, r, i, st)), ∀ i, bytes, ty, r0, str, st, r, refs. # refs < # refs0 → (okbytearray(r, st) ∧ validrefs(str, r0 ' + refs, ty, putByteArray(bytes, r, i, st)) → junkref(str, r0, st) ∨ validrefs(str, r0 ' + refs, ty, st)) ⊦ r0 = jvmref, validrefs(str, r0 ' + refs0, ty, st), junkref(str, r0, st)
