Proof step 14 from proof union-init-01 (previous step)

⊦ (jvmref -- mkfs(class, void_type, `initstate' .field) ') × initval(undone) ∈ st ∪ st0 ∨ ¬ jvmref -- mkfs(class, void_type, `initstate' .field) ' ∈ st ∪ st0 ∧ _uninit ∈ st ∪ st0 ↔ initundone(class, st0), jvmref ∈ st

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 2:
⊦ rk ∈ st ∪ st0 ↔ rk ∈ st ∨ rk ∈ st0
Proof step 13:
⊦ ¬ jvmref -- mkfs(class, void_type, `initstate' .field) ' ∈ st ∧ ¬ jvmref -- mkfs(class, void_type, `initstate' .field) ' ∈ st0 ∧ _uninit ∈ st ∪ st0 ∨ jvmref -- mkfs(class, void_type, `initstate' .field) ' ∈ st ∪ st0 ∧ (st ∪ st0)[jvmref -- mkfs(class, void_type, `initstate' .field) '] = initval(undone) ↔ initundone(class, st0), jvmref ∈ st
