Proof step 42 from proof inv-add3 (previous step)

ro.inodes?, fo.inodes?, log-cons(log, fs), node-cons(nd3.key, nd3), node-cons(nd0.key, nd0), node-cons(nd2.key, nd2), ri-cons(ri, fs), ri-inj(ri), ri-inj(fi) ⊦ ⟪fail#(; ; err); adr4 := ?, adr0 := ?, adr := ?; boolvar := ?⟫ true

Heuristic unfold applied rule call right

And obtained the following new goals

Proof step 43:
fo.inodes?, ro.inodes?, log-cons(log, fs), node-cons(nd2.key, nd2), node-cons(nd0.key, nd0), node-cons(nd3.key, nd3), ri-cons(ri, fs), ri-inj(fi), ri-inj(ri) ⊦ ⟪choose err0 with ⌊err0⌋ in err := err0; adr4 := ?, adr0 := ?, adr := ?; boolvar := ?⟫ true

Rule argument

pos: right 1

Additional information

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