Proof step 3 from proof initialization (previous step)

⊦ ⟪ebm_format#(; ; avols, err); if err = ESUCCESS then {v := default-volid; ebm_create_volume#(v, m; avols; err)}⟫ ( (err = ESUCCESS → ⟨ebm_avol_format#(m; ; avol0, err0)⟩ (avol0 = abs(avols[v]) ∧ ESUCCESS = err0)) ∧ (err ≠ ESUCCESS → (∀ avol. ⟨ebm_avol_format#(m; ; avol0, err0)⟩ (avol = avol0 ∧ err = err0))))

Heuristic nonrecursive calls applied rule call right

And obtained the following new goals

Proof step 4:
⊦ ⟪fail_or_success#(; ; err); if err = ESUCCESS then avols := ∅ else avols := ?; if err = ESUCCESS then {v := default-volid; ebm_create_volume#(v, m; avols; err)}⟫ ( (err = ESUCCESS → ⟨ebm_avol_format#(m; ; avol0, err0)⟩ (avol0 = abs(avols[v]) ∧ ESUCCESS = err0)) ∧ (err ≠ ESUCCESS → (∀ avol. ⟨ebm_avol_format#(m; ; avol0, err0)⟩ (avol = avol0 ∧ err = err0))))

pos: right 1

Additional information

Used simplifier rules: ebm_format#(; ; AVOLS, ERR) {fail_or_success#(; ; ERR); if ERR = ESUCCESS then AVOLS := ∅ else AVOLS := ? };
