Proof step 46 from proof junkrefs-put-norefval-01 (previous step)

okval(val, ty0), junkrefs(str, r ' + acc, ty, st[r1 -- mkfs(class, ty0, fieldvar) ', val]), ∀ val, ty0, str, ty, st, r1, class, fieldvar. okval(val, ty0) ∧ junkrefs(str, acc, ty, st[r1 -- mkfs(class, ty0, fieldvar) ', val]) → ty0 = void_type ∨ mkfs(class, ty0, fieldvar) ' = _length ∨ is_referencevalue(val) ∨ junkrefs(str, acc, ty, st) ⊦ ty0 = void_type, mkfs(class, ty0, fieldvar) ' = _length, is_referencevalue(val), junkrefs(str, r ' + acc, ty, st)

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 2:
⊦ r = jvmref → ¬ junkrefs(str, r ' + refs, ty, st)
Proof step 45:
r ≠ jvmref, okval(val, ty0), junkrefs(str, r ' + acc, ty, st[r1 -- mkfs(class, ty0, fieldvar) ', val]), ∀ val, ty0, str, ty, st, r1, class, fieldvar. okval(val, ty0) ∧ junkrefs(str, acc, ty, st[r1 -- mkfs(class, ty0, fieldvar) ', val]) → ty0 = void_type ∨ mkfs(class, ty0, fieldvar) ' = _length ∨ is_referencevalue(val) ∨ junkrefs(str, acc, ty, st) ⊦ ty0 = void_type, mkfs(class, ty0, fieldvar) ' = _length, is_referencevalue(val), junkrefs(str, r ' + acc, ty, st)
