Proof step 39 from proof junkrefs-delete-02 (previous step)

¬ (r0 ≠ jvmref ∧ (¬ is_valid_ref(str, r0, st -- r) ∨ ¬ (st -- r)[r0 -- _type] .type ≤ ty)), junkrefs(str, r0 ' + acc, ty, st), ∀ str, ty, st, r. junkrefs(str, acc, ty, st) → junkrefs(str, acc, ty, st -- r) ⊦ r = r0, junkrefs(str, r0 ' + acc, ty, st -- r)

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 7:
⊦ ¬ junkrefs(str, jvmref ' + refs, ty, st)
Proof step 38:
junkrefs(str, r0 ' + acc, ty, st), is_valid_ref(str, r0, st), st[r0 -- _type] .type ≤ ty, ∀ str, ty, st, r. junkrefs(str, acc, ty, st) → junkrefs(str, acc, ty, st -- r) ⊦ r = r0, r0 = jvmref, junkrefs(str, r0 ' + acc, ty, st -- r)
