Proof step 7 from proof addclass-update-sw (previous step)

∀ r, class0, fis0, st. r = jvmref ∨ update(r, fis1, addclass(class0, fis0, st)) = addclass(class0, fis0, update(r, fis1, st)) ⊦ r = jvmref, (update(r, fis1, addclass(class0, fis0, st))[r -- sk, val]) = addclass(class0, fis0, update(r, (sk × val) ' + fis1, st))

User applied rule all left

And obtained the following new goals

Proof step 6:
r = jvmref ∨ update(r, fis1, addclass(class0, fis0, st)) = addclass(class0, fis0, update(r, fis1, st)), ∀ r, class0, fis0, st. r = jvmref ∨ update(r, fis1, addclass(class0, fis0, st)) = addclass(class0, fis0, update(r, fis1, st)) ⊦ r = jvmref, (update(r, fis1, addclass(class0, fis0, st))[r -- sk, val]) = addclass(class0, fis0, update(r, (sk × val) ' + fis1, st))
