Proof step 67 from proof compat-put (previous step)

compatmode(str, st), compatstatic(str, st), compatrefs(str, st), compat(str, val, ty, st), initdone(class0, st[r -- mkfs(class, ty, fieldvar) ', val]), tdname∃(str, class0) ⊦ mkfs(class, ty, fieldvar) ' = _length, ty = void_type, compatfields(str, jvmref, statfields(class0), st[r -- mkfs(class, ty, fieldvar) ', val])

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 33:
⊦ rk ≠ jvmref -- mkfs(class, void_type, `initstate' .field) ' ∧ rk ≠ _uninit → (initdone(class, st[rk, val]) ↔ initdone(class, st))
Proof step 66:
r -- mkfs(class, ty, fieldvar) ' ≠ jvmref -- mkfs(class0, void_type, `initstate' .field) ' ∧ r -- mkfs(class, ty, fieldvar) ' ≠ _uninit, compatmode(str, st), compatstatic(str, st), compatrefs(str, st), compat(str, val, ty, st), initdone(class0, st), tdname∃(str, class0) ⊦ mkfs(class, ty, fieldvar) ' = _length, ty = void_type, compatfields(str, jvmref, statfields(class0), st[r -- mkfs(class, ty, fieldvar) ', val])
