Proof step 31 from proof refine-isbad (previous step)

err = err0, m < # apebs, abs(pebs, apebs), mtd-cons(pebs), ubi-io-inv(apebs), ⌊err0⌋ ∨ err0 = ESUCCESS ⊦ ⟨aubi_io_isbad#(m, apebs; ; isbad0, err1)⟩ ((isbad ↔ isbad0) ∧ err = err1), err = ESUCCESS

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 32:
m < # apebs, abs(pebs, apebs), mtd-cons(pebs), ubi-io-inv(apebs), ⌊err0⌋ ⊦ ⟨aubi_io_isbad#(m, apebs; ; isbad0, err1)⟩ ((isbad ↔ isbad0) ∧ err0 = err1)

Rule argument

Additional information

Used simplifier rules: ⊦ ⌊err⌋ → err ≠ ESUCCESS; (s)
