Proof step 32 from proof replay-prog (previous step)

ri = replay-log(log, fs, fi ⊖ fo), ro = ∅, fo.inodes?, replay-safe(log, fs, fi ⊖ fo) ⊦ ⟪fail_or_success#(; ; err); boolvar := err = ESUCCESS⟫ ((err = ESUCCESS ∨ ⌊err⌋ ) ∧ (err = ESUCCESS → boolvar))

Heuristic unfold applied rule call right

And obtained the following new goals

Proof step 33:
ri = replay-log(log, fs, fi ⊖ fo), ro = ∅, fo.inodes?, replay-safe(log, fs, fi ⊖ fo) ⊦ ⟪choose err0 with ⌊err0⌋ ∨ err0 = ESUCCESS in err := err0; boolvar := err = ESUCCESS⟫ ((err = ESUCCESS ∨ ⌊err⌋ ) ∧ (err = ESUCCESS → boolvar))

Rule argument

pos: right 1

Additional information

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