Proof step 7 from proof crash-neutral-markbad (previous step)

apebs[n] = mkpeb(aehdr, avhdr, buf, m, false), apebs0 = apebs, n < # apebs, ubi-io-inv(apebs), ubi-io-markbad-pre(n, apebs) ⊦ ⟨fail_or_success#(; ; err); if err = ESUCCESS then apebs[n].bad := true⟩ (apebs0 = apebs)

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 8:
apebs[n] = mkpeb(aehdr, avhdr, buf, m, false), n < # apebs, ubi-io-inv(apebs) ⊦ ⟨fail_or_success#(; ; err); apebs0 := apebs; if err = ESUCCESS then apebs[n].bad := true⟩ (apebs0 = apebs)

Rule argument

Additional information

Used simplifier rules: ⊦ mkpeb(aehdr, avhdr, buf, m, boolvar).bad ↔ boolvar; (s)% ⊦ ubi-io-markbad-pre(n, apebs) ↔ n < # apebs ∧ ¬ apebs[n].bad; (s)
