Proof step 6 from proof ac-bad-02 (previous step)

fs = mkfs(class, ty, fieldvar), ∀ class1, i, val, fis1, st. addclass(class1, fis0 + (i ' × val) ' + fis1, st) = addclass(class1, fis0 + fis1, st) ⊦ addclass(class, ((fs ' × val0) ' + fis0) + (i ' × val) ' + fis1, st) = addclass(class, ((fs ' × val0) ' + fis0) + fis1, st)

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:
∀ class1, i, val, fis1, st. addclass(class1, fis0 + (i ' × val) ' + fis1, st) = addclass(class1, fis0 + fis1, st) ⊦ (addclass(class, fis0 + (i ' × val) ' + fis1, st)[jvmref -- mkfs(class, ty, fieldvar) ', val0]) = (addclass(class, fis0 + fis1, st)[jvmref -- mkfs(class, ty, fieldvar) ', val0])
