Proof step 35 from proof fsync-inode-inv (previous step)

icache[m] = mkientry(true, mkinode(m1, md, boolvar, m2, m3, m4)), files[m] = mkfile(m0, md0, # links(m, dirs), content), files[m1] = mkfile(m5, md1, m6, content0), afs-cons(dirs, files), dcache-cons(dcache, dirs, files), icache-cons(icache, dirs, files), pcache-cons(pcache, dirs, files), synced(dirs, icache, pcache), m ∈ icache, m ∈ files ⊦ m1 ∈ files ∧ m2 = m6 ∧ m3 = 0 ∧ ¬ boolvar, m1 ∈ dirs ∧ m2 = dirs[m1].nlink ∧ m4 = dirs[m1].size ∧ m3 = dirs[m1].nsubdirs ∧ boolvar

Heuristic elimination applied rule insert elim lemma

And obtained the following new goals

Proof step 36:
files[m1] = mkfile(m5, md1, m6, content0), files[m] = mkfile(m0, md0, # links(m, dirs), content), icache[m] = mkientry(true, mkinode(m1, md, boolvar, m2, m3, m4)), dirs[m1] = mkdir(m7, md2, m8, m9, entries), afs-cons(dirs, files), dcache-cons(dcache, dirs, files), icache-cons(icache, dirs, files), pcache-cons(pcache, dirs, files), synced(dirs, icache, pcache), m ∈ files, m ∈ icache ⊦ m1 ∈ dirs ∧ m2 = m8 ∧ m4 = m7 ∧ m3 = m9 ∧ boolvar, m1 ∈ files ∧ m2 = m6 ∧ m3 = 0 ∧ ¬ boolvar

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] → [dirs[m1], m7, md2, m8, m9, 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: dirs[m1], m7, md2, m8, m9, entries
