Proof step 17 from proof sw-del-add (previous step)

r1 ∈ H ⊦ H[r1] = (H ++ r)[r1], r = null, r0 = r, r1 = r0, r ∈ H

User applied rule insert rewrite lemma

And obtained the following new goals

Rule argument

spec: <toplevel> name: at-alloc seq: r ∈ H, r0 ≠ null, ¬ r0 ∈ H ⊦ r ≠ r0 → (H ++ r0)[r] = H[r] subst: [r, r0, H] → [r1, r, H] flags: <all paths>

Additional information

Used terms: r1, r, H
