Proof step 3 from proof addclass-switch (previous step)

⊦ (st[r -- i ', val][jvmref -- mkfs(class, void_type, `initstate' .field) ', initval(done)]) = (st[jvmref -- mkfs(class, void_type, `initstate' .field) ', initval(done)][r -- i ', val])

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 2:
⊦ rk ≠ rk0 → (st[rk0, val][rk, val0]) = (st[rk, val0][rk0, val])

Rule argument

[speclemmaarg: ,rk ≠ rk0 → (st[rk0, val][rk, val0]) = (st[rk, val0][rk0, val]) ,[val0, rk, val, rk0, st] → [val, r -- i ', initval(done), jvmref -- mkfs(class, void_type, `initstate' .field) ', st] ,F ,store ,javastore ,rew ]
