Proof step 23:
⊦ fits(r, sks, st) ∧ ¬ is_reftype(ty) ∧ ¬ junkref(str, r, st) → (mkfs(class, ty, fieldvar) ' ∈ sks ↔ ¬ ¬ (mkfs(class, ty, fieldvar) ' = sks .last ∧ sks ≠ []))
Proof step 28:
st[r0 -- sks] = refval(r2), st[r -- sks1] = refval(r1), fits(r, sks1, st), junkref(str, r1, st), fits(r0, sks, st), fits(r2, mkfs(class, ty, fieldvar) ' ', st), fits(r1, i ' ', st) ⊦ mkfs(class, ty, fieldvar) ' = sks1 .last, sks = [], sks1 = [], (st[r1 -- i ', val][(st[r1 -- i ', val][r0 -- sks]) .refval -- mkfs(class, ty, fieldvar) ', val0]) = (st[r1 -- i ', val][r2 -- mkfs(class, ty, fieldvar) ', val0]), is_referencevalue(val), is_referencevalue(val0), is_referencevalue(st[r1 -- i ']), is_reftype(ty), junkref(str, r, st), junkref(str, r0, st)
