Proof step 167 from proof afs-cons-rename-file-negdentry (previous step)

# links(m0, dirs0) = dirs0[m0].nlink, dirs0[m0] = mkdir(dirs0[m0].size, md3, dirs0[m0].nlink, dirs0[m0].nsubdirs, entries), files[entries1[str]] = mkfile(m2, md, # links(entries1[str], dirs0), content0), dirs0[m] = mkdir(0, md2, # links(m, dirs0), m4, entries1), afs-cons(dirs0, files), m0 ∈ dirs0, entries1[str] ∈ files, m ∈ dirs0, str ∈ entries1, m0 = m → md1 = md0, links(m0, dirs0) ≠ ∅ ∨ m0 = ROOT_INO, links(m, dirs0) ≠ ∅ ∨ m = ROOT_INO ⊦ str0 ∈ dirs0[m0].entries, str0 ∈ entries

Heuristic elimination applied rule insert elim lemma

And obtained the following new goals

Proof step 168:
# links(m0, dirs0) = m3, dirs0[m] = mkdir(0, md2, # links(m, dirs0), m4, entries1), files[entries1[str]] = mkfile(m2, md, # links(entries1[str], dirs0), content0), dirs0[m0] = mkdir(m1, md3, m3, m5, entries), dirs0[m0] = mkdir(m1, md4, m3, m5, entries0), afs-cons(dirs0, files), str ∈ entries1, m ∈ dirs0, entries1[str] ∈ files, m0 ∈ dirs0, m0 = m → md1 = md0, links(m, dirs0) ≠ ∅ ∨ m = ROOT_INO, links(m0, dirs0) ≠ ∅ ∨ m0 = ROOT_INO ⊦ str0 ∈ entries, str0 ∈ entries0

Rule argument

spec: abstract-dir name: elim seq: ⊦ ( ((m = ad.size ∧ md = ad.meta) ∧ m0 = ad.nlink) ∧ m1 = ad.nsubdirs) ∧ entries = ad.entries ↔ ad = mkdir(m, md, m0, m1, entries) subst: [ad, m, md, m0, m1, entries] → [dirs0[m0], m1, md4, m3, m5, entries0]

Additional information

Used simplifier rules: ⊦ ( ((m = ad.size ∧ md = ad.meta) ∧ m0 = ad.nlink) ∧ m1 = ad.nsubdirs) ∧ entries = ad.entries ↔ ad = mkdir(m, md, m0, m1, entries); (elim) Used terms: dirs0[m0], m1, md4, m3, m5, entries0
