Proof step 28 from proof overwrite-write-inode-dirty (previous step)

icache[ino0] = mkientry(boolvar0, mkinode(m0, md0, true, m1, m2, m3)), icache[ino] = mkientry(boolvar, inode), ino ∈ icache, ino ∈ files, ino0 ∈ files, ino0 ∈ icache ⊦ ino0 = ino, mkfile(files[ino0].size, files[ino0].meta, files[ino0].nlink, files[ino0].content ⊕ mkcontent(ino0, pcache)) = ((files ⊕ pcache) ⊕ icache[ino, mkientry(true, (inode.meta:= md).size:= m)])[ino0], inode.directory

Heuristic elimination applied rule insert elim lemma

And obtained the following new goals

Proof step 29:
icache[ino] = mkientry(boolvar, inode), icache[ino0] = mkientry(boolvar0, mkinode(m0, md0, true, m1, m2, m3)), files[ino0] = mkfile(m4, md1, m5, content), ino0 ∈ icache, ino0 ∈ files, ino ∈ files, ino ∈ icache ⊦ ino0 = ino, mkfile(m4, md1, m5, content ⊕ mkcontent(ino0, pcache)) = ((files ⊕ pcache) ⊕ icache[ino, mkientry(true, (inode.meta:= md).size:= m)])[ino0], inode.directory

Rule argument

spec: abstract-file name: elim seq: ⊦ ((m = af.size ∧ md = af.meta) ∧ m0 = af.nlink) ∧ content = af.content ↔ af = mkfile(m, md, m0, content) subst: [af, m, md, m0, content] → [files[ino0], m4, md1, m5, content]

Additional information

Used simplifier rules: ⊦ ((m = af.size ∧ md = af.meta) ∧ m0 = af.nlink) ∧ content = af.content ↔ af = mkfile(m, md, m0, content); (elim) Used terms: files[ino0], m4, md1, m5, content
