Proof step 6 from proof ac-getbar (previous step)

fs = mkfs(class0, ty, fieldvar), ∀ r, class, st. r = jvmref ∨ getbytearray(r, addclass(class, fis0, st)) = getbytearray(r, st) ⊦ getbytearray(r, addclass(class0, (fs ' × val) ' + fis0, st)) = getbytearray(r, st), r = jvmref

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 4:
⊦ addclass(class1, (mkfs(class1, ty, fieldvar) ' × val) ' + fis, st) = (addclass(class1, fis, st)[jvmref -- mkfs(class1, ty, fieldvar) ', val])
Proof step 5:
∀ r, class, st. r = jvmref ∨ getbytearray(r, addclass(class, fis0, st)) = getbytearray(r, st) ⊦ r = jvmref, getbytearray(r, addclass(class0, fis0, st)) = getbytearray(r, st)

Rule argument
