Proof step 47 from proof junkrefs-put-norefval-01 (previous step)

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