Proof step 63 from proof inv-truncate (previous step)

# links(ino0, dirs) = m1, files[ino0] = mkfile(m, md, m1, content), files[ino0] = mkfile(m0, md0, m1, content0), buf-opt = none, err = ESUCCESS, inode = mkinode(ino0, md, false, m1, 0, m), afs-cons(dirs, files), ispath(p, ROOT_INO, ino0, dirs, files), of-cons(of, dirs, files), pw(user, md), px-parent(user, p, ROOT_INO, dirs, files), ino0 ∈ files ⊦ [afs_truncate#(n, m / VFS_PAGE_SIZE; buf-opt, inode, isdir0, err, dirs, files, bv)] (afs-cons(dirs, files) → of-cons(of, dirs, files)), ino0 ∈ dirs

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 64:
files[ino0] = mkfile(m0, md0, # links(ino0, dirs), content0), buf-opt = none, err = ESUCCESS, inode = mkinode(ino0, md0, false, # links(ino0, dirs), 0, m0), afs-cons(dirs, files), ispath(p, ROOT_INO, ino0, dirs, files), of-cons(of, dirs, files), pw(user, md0), px-parent(user, p, ROOT_INO, dirs, files), ino0 ∈ files, ¬ ino0 ∈ dirs ⊦ [afs_truncate#(n, m0 / VFS_PAGE_SIZE; buf-opt, inode, isdir0, err, dirs, files, bv)] (afs-cons(dirs, files) → of-cons(of, dirs, files))

Rule argument

Additional information

Used simplifier rules: ⊦ mkfile(m, md, m0, content) = mkfile(m1, md0, m2, content0) ↔ m = m1 ∧ md = md0 ∧ m0 = m2 ∧ content = content0; (ws)
