Proof step 69 from proof compat-put (previous step)

compat(str, val, ty, st), compatrefs(str, st), compatstatic(str, st), compatmode(str, st) ⊦ compatstatic(str, st[r -- mkfs(class, ty, fieldvar) ', val]), ty = void_type, mkfs(class, ty, fieldvar) ' = _length

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 32:
⊦ compatstatic(str, st) ↔ (∀ class. tdname∃(str, class) ∧ initdone(class, st) → compatfields(str, jvmref, statfields(class), st))
Proof step 68:
compat(str, val, ty, st), compatrefs(str, st), compatstatic(str, st), compatmode(str, st) ⊦ ∀ class0. tdname∃(str, class0) ∧ initdone(class0, st[r -- mkfs(class, ty, fieldvar) ', val]) → compatfields(str, jvmref, statfields(class0), st[r -- mkfs(class, ty, fieldvar) ', val]), ty = void_type, mkfs(class, ty, fieldvar) ' = _length

Rule argument

[crewrite-arg: static-compat , F , [st, str] → [st[r -- mkfs(class, ty, fieldvar) ', val], str] ]
