Proof step 35 from proof inv-write_inode (previous step)

dirs[m] = mkdir(m5, md1, m6, m7, entries), files[m] = mkfile(m3, md0, m4, content), afs-cons(dirs, files), m ∈ dirs ∧ m0 = m6 ∧ m2 = m5 ∧ m1 = m7 ∧ boolvar ∨ m ∈ files ∧ m0 = m4 ∧ m1 = 0 ∧ ¬ boolvar ⊦ ⟪fail#(; ; err); asynced := ?⟫ afs-cons(dirs, files)

Heuristic unfold applied rule call right

And obtained the following new goals

Proof step 36:
files[m] = mkfile(m3, md0, m4, content), dirs[m] = mkdir(m5, md1, m6, m7, entries), afs-cons(dirs, files), m ∈ dirs ∧ m0 = m6 ∧ m2 = m5 ∧ m1 = m7 ∧ boolvar ∨ m ∈ files ∧ m0 = m4 ∧ m1 = 0 ∧ ¬ boolvar ⊦ ⟪choose err0 with ⌊err0⌋ in err := err0; asynced := ?⟫ afs-cons(dirs, files)

Rule argument

pos: right 1

Additional information

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