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] → [(key.ino = m1 ⊃ mkdir (m0 + 1, md1, # links(key.ino, dirs0), m4, entries1[str, ino0]) ;dirs0[key.ino] ), m, md0, m2, m3, entries]

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: (key.ino = m1 ⊃ mkdir(m0 + 1, md1, # links(key.ino, dirs0), m4, entries1[str, ino0]) ;dirs0[key.ino] ), m, md0, m2, m3, entries
