Proof step 38 from proof inv-link (previous step)

c_inode = inode, dent = negdentry(str), err = ENOTDIR, err0 = ESUCCESS, err1 = ESUCCESS, ino = ino0, inode = getinode(ino, dirs, files), afs-cons(dirs, files), ispath(q, ROOT_INO, ino0, dirs, files), of-cons(of, dirs, files), px-parent(user, q, ROOT_INO, dirs, files), ino0 ∈ dirs ∨ ino0 ∈ files ⊦ ⟪if err = ESUCCESS then afs_link#(dent; new_inode, c_inode, new_dent, err, dirs, files; asynced)⟫ (of-cons(of, dirs, files) ∧ afs-cons(dirs, files)), p = ε, inode.directory

Heuristic symbolic execution applied rule if negative right

And obtained the following new goals

Proof step 39:
c_inode = inode, dent = negdentry(str), err = ENOTDIR, err0 = ESUCCESS, err1 = ESUCCESS, ino = ino0, inode = getinode(ino, dirs, files), afs-cons(dirs, files), ispath(q, ROOT_INO, ino0, dirs, files), of-cons(of, dirs, files), px-parent(user, q, ROOT_INO, dirs, files), ino0 ∈ dirs ∨ ino0 ∈ files ⊦ ⟪skip⟫ (of-cons(of, dirs, files) ∧ afs-cons(dirs, files)), p = ε, inode.directory

Rule argument

pos: right 1
