Proof step 4 from proof crash-neutral-entries (previous step)

boolvar ↔ true, fo.inodes?, ro.inodes?, log-cons(log, fs), ri-inj(fi), ri-inj(ri) ⊦ ⟨fail_or_success#(; ; err); if err = ESUCCESS then strings := dentries(key, ri) else strings := ?⟩ true

Heuristic unfold applied rule call right

And obtained the following new goals

Proof step 5:
boolvar ↔ true, ro.inodes?, fo.inodes?, log-cons(log, fs), ri-inj(ri), ri-inj(fi) ⊦ ⟨choose err0 with ⌊err0⌋ ∨ err0 = ESUCCESS in err := err0; if err = ESUCCESS then strings := dentries(key, ri) else strings := ?⟩ true

Rule argument

pos: right 1

Additional information

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