Proof step 3 from proof validref-put-norefval-01 (previous step)

fs = mkfs(class, ty0, fieldvar), okval(val, ty0), validref(str, r, ty, st) ⊦ ty0 = void_type, fs ' = _length, is_referencevalue(val), validref(str, r, ty, st[r1 -- fs ', val])

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 2:
okval(val, ty0), validref(str, r, ty, st) ⊦ ty0 = void_type, mkfs(class, ty0, fieldvar) ' = _length, is_referencevalue(val), validref(str, r, ty, st[r1 -- mkfs(class, ty0, fieldvar) ', val])

Rule argument
