Proof step 8 from proof inv-markbad (previous step)

pebs[m] = mkpeb(buf, m0, false), m < # pebs, mtd-cons(pebs) ⊦ ⟪fail_or_success#(; ; err); if err = ESUCCESS then pebs[m].bad := true⟫ mtd-cons(pebs)

Heuristic unfold applied rule call right

And obtained the following new goals

Proof step 9:
pebs[m] = mkpeb(buf, m0, false), m < # pebs, mtd-cons(pebs) ⊦ ⟪choose err0 with ⌊err0⌋ ∨ err0 = ESUCCESS in err := err0; if err = ESUCCESS then pebs[m].bad := true⟫ mtd-cons(pebs)

Rule argument

pos: right 1

Additional information

Used simplifier rules: fail_or_success#(; ; ERR) {choose ERR0 with ⌊ERR0⌋ ∨ ERR0 = ESUCCESS in ERR := ERR0};
