Proof step 56 from proof addobj-addclass-sw (previous step)

¬ r0 ≠ jvmref ⊦ r = jvmref, r0 = r, (r0 -- sk ∈ addclass(class0, fis0, st) ↔ r0 -- sk ∈ addclass(class0, fis0, addobj(r, class, fis, st))) ∧ (addclass(class0, fis0, st)[r0 -- sk]) = (addclass(class0, fis0, addobj(r, class, fis, st))[r0 -- sk])

Proof step 55:
⊦ jvmref = r, (jvmref -- sk ∈ addclass(class0, fis0, st) ↔ jvmref -- sk ∈ addclass(class0, fis0, addobj(r, class, fis, st))) ∧ (addclass(class0, fis0, st)[jvmref -- sk]) = (addclass(class0, fis0, addobj(r, class, fis, st))[jvmref -- sk])
