Proof step 12 from proof ac-del-01 (previous step)

∀ class1, sk, val0, st, val. (addclass(class1, fis0 + (sk × val0) ', st)[jvmref -- sk, val]) = (addclass(class1, fis0, st)[jvmref -- sk, val]) ⊦ (addclass(class, fis0 + (sk × val0) ', st)[jvmref -- sk, val][jvmref -- mkfs(class, ty, fieldvar) ', val1]) = (addclass(class, fis0, st)[jvmref -- mkfs(class, ty, fieldvar) ', val1][jvmref -- sk, val]), sk = mkfs(class, ty, fieldvar) '

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 9:
⊦ rk ≠ rk0 → (st[rk0, val][rk, val0]) = (st[rk, val0][rk0, val])
Proof step 11:
jvmref -- sk ≠ jvmref -- mkfs(class, ty, fieldvar) ', ∀ class1, sk, val0, st, val. (addclass(class1, fis0 + (sk × val0) ', st)[jvmref -- sk, val]) = (addclass(class1, fis0, st)[jvmref -- sk, val]) ⊦ (addclass(class, fis0 + (sk × val0) ', st)[jvmref -- sk, val][jvmref -- mkfs(class, ty, fieldvar) ', val1]) = (addclass(class, fis0, st)[jvmref -- sk, val][jvmref -- mkfs(class, ty, fieldvar) ', val1]), sk = mkfs(class, ty, fieldvar) '
