Proof step 191 from proof overwrite-write-page-dirty (previous step)

files[ino0] = mkfile(m4, md0, m5, content), icache[ino0] = mkientry(boolvar, mkinode(m0, md, false, m1, m2, m3)), ino0 ∈ icache, ino ∈ files, ino0 ∈ files, datakey(ino0, n) ∈ pcache[datakey(ino, m), mkpentry(true, buf)] ⊦ (content ⊕ mkcontent(ino0, pcache))[n] = pcache[datakey(ino, m), mkpentry(true, buf)][datakey(ino0, n)].page, ino ∈ icache

Heuristic elimination applied rule insert elim lemma

And obtained the following new goals

Proof step 192:
icache[ino0] = mkientry(boolvar, mkinode(m0, md, false, m1, m2, m3)), files[ino0] = mkfile(m4, md0, m5, content), pcache[datakey(ino, m), mkpentry(true, buf)][datakey(ino0, n)] = mkpentry(boolvar0, buf0), datakey(ino0, n) ∈ pcache[datakey(ino, m), mkpentry(true, buf)], ino0 ∈ files, ino ∈ files, ino0 ∈ icache ⊦ (content ⊕ mkcontent(ino0, pcache))[n] = buf0, ino ∈ icache

Rule argument

spec: pcache-entry name: elim seq: ⊦ (boolvar ↔ pe.dirty) ∧ buf = pe.page ↔ pe = mkpentry(boolvar, buf) subst: [pe, boolvar, buf] → [pcache[datakey(ino, m), mkpentry(true, buf)] [datakey(ino0, n) ], boolvar0, buf0]

Additional information

Used simplifier rules: ⊦ (boolvar ↔ pe.dirty) ∧ buf = pe.page ↔ pe = mkpentry(boolvar, buf); (elim) Used terms: pcache[datakey(ino, m), mkpentry(true, buf)][datakey(ino0, n)], boolvar0, buf0
