Proof step 8 from proof validstatfields-class-01 (previous step)

initdone(class, st), tdname∃(str, class), mkfs(class0, ty, fieldvar) ' ∈ statfields(class), validfield(str, jvmref, mkfs(class0, ty, fieldvar) ', st) ⊦ tdname∃(str, class0) ∧ mkfs(class0, ty, fieldvar) ' ∈ statfields(class0)

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 4:
⊦ validfield(str, r, sk, st) ↔ is_fskey(sk) ∧ r -- sk ∈ st ∧ type∃(str, sk .fs .type) ∧ sk .fs .type ≠ void_type ∧ validval(str, st[r -- sk], sk .fs .type, st)
Proof step 7:
initdone(class, st), tdname∃(str, class), mkfs(class0, ty, fieldvar) ' ∈ statfields(class), is_fskey(mkfs(class0, ty, fieldvar) ') ∧ jvmref -- mkfs(class0, ty, fieldvar) ' ∈ st ∧ type∃(str, mkfs(class0, ty, fieldvar) ' .fs .type) ∧ mkfs(class0, ty, fieldvar) ' .fs .type ≠ void_type ∧ validval(str, st[jvmref -- mkfs(class0, ty, fieldvar) '], mkfs(class0, ty, fieldvar) ' .fs .type, st) ⊦ tdname∃(str, class0) ∧ mkfs(class0, ty, fieldvar) ' ∈ statfields(class0)
