Proof step 22 from proof initialization (previous step)

⊦ ⟨ebm_avol_format#(m; ; avol0, err1)⟩ (avol0 = abs(fill(mkabstractvolume(m), erased)) ∧ ESUCCESS = err1)

Heuristic nonrecursive calls applied rule call right

And obtained the following new goals

Proof step 23:
⊦ ⟨fail_or_success#(; ; err); if err = ESUCCESS then avol := fill(mkavolume(m), unmapped) else avol := ?⟩ (avol = abs(fill(mkabstractvolume(m), erased)) ∧ ESUCCESS = err)

Rule argument

pos: right 1

Additional information

Used simplifier rules: ebm_avol_format#(VOLSIZE; ; AVOL, ERR) {fail_or_success#(; ; ERR); if ERR = ESUCCESS then AVOL := fill(mkavolume(VOLSIZE), unmapped) else AVOL := ? };
