Proof step 52 from proof inv-rmdir (previous step)

isdir1 ↔ true, isdir ↔ isdir2, isrename ↔ false, isdir0 ↔ isdir, dent = negdentry(str), err = EACCESS, err0 = ESUCCESS, err1 = ESUCCESS, ino = ino1, inode = getinode(ino, dirs, files), isdir2, inode.directory, dom of < ino0, afs-cons(dirs, files), ispath(q, ROOT_INO, ino1, dirs, files), of-cons(of, dirs, files), pre-iget(ino, dirs, files), px-parent(user, q, ROOT_INO, dirs, files), ¬ px(user, inode.meta) ∨ ¬ pw(user, inode.meta) ⊦ ⟪if err = ESUCCESS then {afs_rmdir#(; inode, p_inode, dent, err, dirs, files; asynced); vfs_put_inode#(p_inode, of, asynced; err, dirs, files)}⟫ (of-cons(of, dirs, files) ∧ afs-cons(dirs, files))

Heuristic symbolic execution applied rule if negative right

And obtained the following new goals

Proof step 53:
isdir0 ↔ isdir, isrename ↔ false, isdir ↔ isdir2, isdir1 ↔ true, dent = negdentry(str), err = EACCESS, err0 = ESUCCESS, err1 = ESUCCESS, ino = ino1, inode = getinode(ino, dirs, files), isdir2, inode.directory, dom of < ino0, afs-cons(dirs, files), ispath(q, ROOT_INO, ino1, dirs, files), of-cons(of, dirs, files), pre-iget(ino, dirs, files), px-parent(user, q, ROOT_INO, dirs, files), ¬ px(user, inode.meta) ∨ ¬ pw(user, inode.meta) ⊦ ⟪skip⟫ (of-cons(of, dirs, files) ∧ afs-cons(dirs, files))

Rule argument

pos: right 1
