Proof step 39 from proof validstatfields-put-statfield-06 (previous step)

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

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 2:
⊦ ¬ initdone(class, st) → (validstatfields(str, statfields(class), st) ↔ statfields(class) = [] ∨ tdname∃(str, class))
Proof step 34:
¬ ¬ initdone(class, st[jvmref -- mkfs(class0, void_type, `initstate' .field) ', val]) ⊦ class0 = class, validstatfields(str, statfields(class), st[jvmref -- mkfs(class0, void_type, `initstate' .field) ', val]) ↔ validstatfields(str, statfields(class), st)
Proof step 38:
¬ initdone(class, st[jvmref -- mkfs(class0, void_type, `initstate' .field) ', val]) ⊦ class0 = class, statfields(class) = [] ∨ tdname∃(str, class) ↔ validstatfields(str, statfields(class), st)
