Proof step 33 from proof validstatfields-put-statfield-06 (previous step)

initdone(class, st[jvmref -- mkfs(class0, void_type, `initstate' .field) ', val]) ⊦ validstatfields(str, statfields(class), st[jvmref -- mkfs(class0, void_type, `initstate' .field) ', val]) ↔ validstatfields(str, statfields(class), st), class0 = class

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 3:
⊦ rk ≠ jvmref -- mkfs(class, void_type, `initstate' .field) ' ∧ rk ≠ _uninit → (initdone(class, st[rk, val]) ↔ initdone(class, st))
Proof step 32:
jvmref -- mkfs(class0, void_type, `initstate' .field) ' ≠ jvmref -- mkfs(class, void_type, `initstate' .field) ' ∧ jvmref -- mkfs(class0, void_type, `initstate' .field) ' ≠ _uninit, initdone(class, st) ⊦ validstatfields(str, statfields(class), st[jvmref -- mkfs(class0, void_type, `initstate' .field) ', val]) ↔ validstatfields(str, statfields(class), st), class0 = class
