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 25:
st[r0 -- sks] = refval(r2), st[r -- sks1] = refval(r1), fits(r0, sks, st), fits(r, sks1 + mkfs(class, ty, fieldvar) ' ', st), junkref(str, r2, st), i ' ∈ sks1, fits(r2, i ' ', st) ⊦ mkfs(class, ty, fieldvar) ' = sks .last, sks = [], (st[r2 -- i ', val0][r1 -- mkfs(class, ty, fieldvar) ', val]) = (st[r2 -- i ', val0][(st[r2 -- i ', val0][r -- sks1]) .refval -- mkfs(class, ty, fieldvar) ', val]), sks1 = [], is_referencevalue(val), is_referencevalue(val0), is_reftype(ty), is_referencevalue(st[r2 -- i ']), junkref(str, r, st), junkref(str, r0, st)
