Proof step 39 from proof eq-io-readdir (previous step)

⟨if pre-readdir(inode.ino, dirs, files) then {{strings0 := dom dirs[inode.ino].entries; err := ESUCCESS} or {choose strings with true in strings0 := strings; fail#(; ; err)}} else abort⟩ (strings0 = strings1 ∧ err = err0), asynced ↔ asynced0, dirs = dirs1, files = files1, inode = mkinode(m, md, boolvar, m0, m1, m2), strings0 = strings ⊦ m ∈ dirs1

Heuristic symbolic execution applied rule if negative left

And obtained the following new goals

Proof step 40:
⟨abort⟩ (strings0 = strings1 ∧ err = err0), asynced ↔ asynced0, dirs = dirs1, files = files1, inode = mkinode(m, md, boolvar, m0, m1, m2), strings0 = strings ⊦ m ∈ dirs1

Rule argument

Additional information

Used simplifier rules: ⊦ mkinode(m, md, boolvar, m0, m1, m2).ino = m; (s)% ⊦ pre-readdir(ino, dirs, files) ↔ valid-dir-ino(ino, dirs, files); (s)% ⊦ valid-dir-ino(ino, dirs, files) ↔ ino ∈ dirs; (s)
