Proof step 1 from proof inv-iget (conclusion)

afs-cons(dirs, files), pre-iget(ino, dirs, files) ⊦ ⟪afs_iget#(ino, dirs, files, asynced; inode, err)⟫ true

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 2:
afs-cons(dirs, files), ino ∈ dirs ∨ ino ∈ files ⊦ ⟪afs_iget#(ino, dirs, files, asynced; inode, err)⟫ true

Rule argument

Additional information

Used simplifier rules: ⊦ valid-ino(ino, dirs, files) ↔ ino ∈ dirs ∨ ino ∈ files; (s)% ⊦ pre-iget(ino, dirs, files) ↔ valid-ino(ino, dirs, files); (s)
