Proof step 3 from proof split-uni (previous step)

rs0 ∩ rs1 = ∅, P0(mk(rs0, f)), P1(mk(rs1, f)) ⊦ ((P0 * P1))(mk(rs0, f) ∪ mk(rs1, f))

User applied rule insert rewrite lemma

And obtained the following new goals

Rule argument

spec: heap-sep name: split-union seq: ⊦ P0(H0) ∧ P1(H1) ∧ H0 ⊥ H1 → ((P0 * P1))(H0 ∪ H1) subst: [H1, H0, P1, P0] → [mk(rs1, f), mk(rs0, f), P1, P0] flags: <all paths>

Additional information

Used simplifier rules: disj: ⊦ mk(rs0, f0) ⊥ mk(rs1, f1) ↔ rs0 ∩ rs1 = ∅; Used terms: mk(rs1, f), mk(rs0, f), P1, P0
