Proof step 602 from proof overwrite-write-page-clean (previous step)

files[ino] = mkfile(m2, md0, m3, content0), icache[ino0] = mkientry(boolvar, mkinode(m0, md, false, m1, m4, m5)), files[ino0] = mkfile(m6, md1, m7, content), ino0 ∈ files, ino ∈ files, ino0 ∈ icache ⊦ m ∈ content ⊕ mkcontent(ino0, pcache) ↔ m ∈ content ∨ datakey(ino0, m) ∈ pcache[datakey(ino, m), mkpentry(false, buf)], ino ∈ icache

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 603:
⊦ key ∈ pcache[key0, pe] ↔ key = key0 ∨ key ∈ pcache

Rule argument

spec: store, inst: pcache-wb name: In-insert seq: ⊦ key ∈ pcache[key0, pe] ↔ key = key0 ∨ key ∈ pcache subst: [pe, key0, pcache, key] → [mkpentry(false, buf), datakey(ino, m), pcache, datakey(ino0, m)] flags: <all paths>

Additional information

Used simplifier rules: in-overwrite-content: ⊦ n ∈ content0 ⊕ content1 ↔ n ∈ content0 ∨ n ∈ content1;%in-mkcontent: ⊦ n ∈ mkcontent(ino, pcache) ↔ datakey(ino, n) ∈ pcache;%in-overwrite-content: ⊦ n ∈ content0 ⊕ content1 ↔ n ∈ content0 ∨ n ∈ content1;% ⊦ datakey(m, m0) = datakey(m1, m2) ↔ m = m1 ∧ m0 = m2; (ws) Used terms: mkpentry(false, buf), datakey(ino, m), pcache, datakey(ino0, m)
