Proof step 90 from proof junkrefs-put-refval-01 (previous step)

st[r0 -- _type] .type ≤ ty0, junkrefs(str, r1 ' + acc, ty, st[r -- mkfs(class, ty0, fieldvar) ', refval(r0)]), ∀ str, ty, st, r0, fs, r. ¬ junkrefs(str, acc, ty, st) ∧ ¬ junkref(str, r0, st) ∧ st[r0 -- _type] .type ≤ fs .type ∧ r0 ≠ jvmref ∧ fs .type ≠ void_type ∧ fs ' ≠ _length → ¬ junkrefs(str, acc, ty, st[r -- fs ', refval(r0)]) ⊦ mkfs(class, ty0, fieldvar) ' = _length, ty0 = void_type, r0 = jvmref, junkref(str, r0, st), junkrefs(str, r1 ' + acc, ty, st)

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 2:
⊦ ¬ r ∈ refs → (junkrefs(str, refs, ty, st[r -- sk, val]) ↔ junkrefs(str, refs, ty, st))
Proof step 89:
¬ ¬ r ∈ r1 ' + acc, st[r0 -- _type] .type ≤ ty0, junkrefs(str, r1 ' + acc, ty, st[r -- mkfs(class, ty0, fieldvar) ', refval(r0)]), ∀ str, ty, st, r0, fs, r. ¬ junkrefs(str, acc, ty, st) ∧ ¬ junkref(str, r0, st) ∧ st[r0 -- _type] .type ≤ fs .type ∧ r0 ≠ jvmref ∧ fs .type ≠ void_type ∧ fs ' ≠ _length → ¬ junkrefs(str, acc, ty, st[r -- fs ', refval(r0)]) ⊦ mkfs(class, ty0, fieldvar) ' = _length, ty0 = void_type, r0 = jvmref, junkref(str, r0, st), junkrefs(str, r1 ' + acc, ty, st)
