Used simplifier rules: abs-fwd: ⊦ n < # pebs ∧ pebs[n] = peb ∧ abs(pebs, apebs) → n < # apebs ∧ abs-peb(peb, apebs[n]); (forward) from specification ubi-io-abs%abs-bad: ⊦ n < # apebs ∧ abs(pebs, apebs) ∧ pebs[n] = mkpeb(buf0, m0, boolvar0) ∧ apebs[n] = mkpeb(aehdr, avhdr, buf, m1, boolvar1) → (boolvar0 ↔ boolvar1); (forward) from specification ubi-io-abs
