Proof step 57 from proof rely-owned-unchgd (previous step)

rs2 ∩ rs1 = ∅, a[P][rs2, f0, g0], ∀ r. (g(r) = a ∧ r ∈ rs ↔ g0(r) = a ∧ r ∈ rs2 ∪ rs1) ∧ (g(r) = a ∧ r ∈ rs → f(r) = f0(r)) ⊦ rs2 ∪ (rs \ rs2) = rs, rs2 ⊆ rs

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 58:
⊦ R[rs, f, g] ↔ R(mk(rs, f, g))
Proof step 59:
rs2 ∩ rs1 = ∅, a[P](mk(rs2, f0, g0)), ∀ r. (g(r) = a ∧ r ∈ rs ↔ g0(r) = a ∧ r ∈ rs2 ∪ rs1) ∧ (g(r) = a ∧ r ∈ rs → f(r) = f0(r)) ⊦ rs2 ∪ (rs \ rs2) = rs, rs2 ⊆ rs

Rule argument

spec: heap-fun, inst: heap-aux name: apply seq: ⊦ R[rs, f, g] ↔ R(mk(rs, f, g)) subst: [g, f, rs, R] → [g0, f0, rs2, a[P]] flags: <all paths>
