Proof step 3 from proof inv-format (previous step)

⊦ ⟪ebm_format#(; ; avols, err); if err = ESUCCESS then {v := default-volid; ebm_create_volume#(v, m; avols; err)}⟫ (err = ESUCCESS → default-volid ∈ avols ∧ v = default-volid ∧ ebm-cons(avols))

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 → default-volid ∈ avols ∧ v = default-volid ∧ ebm-cons(avols))

Rule argument

pos: right 1

Additional information

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