Proof step 863 from proof overwrite-write-page-clean (previous step)

files[ino] = mkfile(m2, md0, m3, content0), pcache[datakey(ino, n)] = mkpentry(boolvar, buf0), ino ∈ files, n ∈ content0, datakey(ino, n) ∈ pcache ⊦ (content0 ⊕ mkcontent(ino, pcache))[n] = buf0, datakey(ino, n) = datakey(ino, m), ino ∈ icache

User applied rule insert rewrite lemma

And obtained the following new goals

Rule argument

spec: <toplevel> name: at-overwrite-content-new seq: ⊦ n ∈ content1 → (content0 ⊕ content1)[n] = content1[n] subst: [n, content1, content0] → [n, mkcontent(ino, pcache), content0] flags: <all paths>

Additional information

Used simplifier rules: at-overwrite-content-old: ⊦ ¬ n ∈ content1 → (content0 ⊕ content1)[n] = content0[n];%in-mkcontent: ⊦ n ∈ mkcontent(ino, pcache) ↔ datakey(ino, n) ∈ pcache;%at-mkcontent: ⊦ mkcontent(ino, pcache)[n] = pcache[datakey(ino, n)].page;%in-mkcontent: ⊦ n ∈ mkcontent(ino, pcache) ↔ datakey(ino, n) ∈ pcache;% ⊦ mkpentry(boolvar, buf).page = buf; (s) Used terms: n, mkcontent(ino, pcache), content0
