Proof step 24 from proof initialization (previous step)

err = ESUCCESS → ubi-io-initial(pebs), err = ESUCCESS → m = EB_PAGE_SIZE ∧ mtd-cons(pebs), err = ESUCCESS ∨ ⌊err⌋ ⊦ ⟨aubi_io_format#(; ; apebs0, err0)⟩ (apebs = apebs0 ∧ err = err0), err = ESUCCESS

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 25:
⌊err⌋ ⊦ ⟨aubi_io_format#(; ; apebs0, err0)⟩ (apebs = apebs0 ∧ err = err0)

Rule argument

Additional information

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