Proof step 15 from proof refine-isbad (previous step)

m < # pebs, m < # apebs, abs(pebs, apebs), mtd-cons(pebs), ubi-io-inv(apebs) ⊦ ⟨aubi_io_isbad#(m, apebs; ; isbad0, err1)⟩ ((pebs[m].bad ↔ isbad0) ∧ ESUCCESS = err1)

Heuristic elimination applied rule insert elim lemma

And obtained the following new goals

Proof step 16:
pebs[m] = mkpeb(buf, m0, boolvar), m < # apebs, m < # pebs, abs(pebs, apebs), mtd-cons(pebs), ubi-io-inv(apebs) ⊦ ⟨aubi_io_isbad#(m, apebs; ; isbad0, err1)⟩ ((boolvar ↔ isbad0) ∧ ESUCCESS = err1)

Rule argument

spec: peb name: elim seq: ⊦ (buf = peb.data ∧ m = peb.fill) ∧ (boolvar ↔ peb.bad) ↔ peb = mkpeb(buf, m, boolvar) subst: [peb, buf, m, boolvar] → [pebs[m], buf, m0, boolvar]

Additional information

Used simplifier rules: ⊦ (buf = peb.data ∧ m = peb.fill) ∧ (boolvar ↔ peb.bad) ↔ peb = mkpeb(buf, m, boolvar); (elim) Used terms: pebs[m], buf, m0, boolvar
