Proof step 17 from proof refine-markbad (previous step)

pebs[m] = mkpeb(buf0, m1, false), apebs[m] = mkpeb(aehdr, avhdr, buf, m0, false), err = ESUCCESS, err = err0, m < # pebs, m < # apebs, abs(pebs, apebs), abs-peb(mkpeb(buf0, m1, false), mkpeb(aehdr, avhdr, buf, m0, false)), mtd-cons(pebs), ubi-io-inv(apebs), ⌊err0⌋ ∨ err0 = ESUCCESS ⊦ ⟪pebs[m].bad := true⟫ ⟨aubi_io_markbad#(m; apebs; err1)⟩ (abs(pebs, apebs) ∧ err = err1)

Heuristic symbolic execution applied rule assign right

And obtained the following new goals

Proof step 18:
apebs[m] = mkpeb(aehdr, avhdr, buf, m0, false), pebs[m] = mkpeb(buf0, m1, false), err = err0, err = ESUCCESS, m < # apebs, m < # pebs, abs(pebs, apebs), abs-peb(mkpeb(buf0, m1, false), mkpeb(aehdr, avhdr, buf, m0, false)), mtd-cons(pebs), ubi-io-inv(apebs), ⌊err0⌋ ∨ err0 = ESUCCESS ⊦ ⟨aubi_io_markbad#(m; apebs; err1)⟩ (abs(pebs[m, pebs[m].bad:= true], apebs) ∧ err = err1)
