Proof step 11 from proof overwrite-write-page-dirty (previous step)

((files ⊕ pcache) ⊕ icache)[ino] = mkfile(m0, md, m1, content), ino ∈ files, ino ∈ icache ⊦ mkfile(m0, md, m1, content[m, buf]) = ((files ⊕ pcache[datakey(ino, m), mkpentry(true, buf)]) ⊕ icache)[ino]

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 12:
⊦ ino ∈ icache ∧ ¬ icache[ino].inode.directory → (files ⊕ icache)[ino] = mkfile(icache[ino].inode.size, icache[ino].inode.meta, icache[ino].inode.nlink, files[ino].content)
Proof step 13:
((files ⊕ pcache) ⊕ icache)[ino] = mkfile(m0, md, m1, content), ino ∈ icache, ino ∈ files ⊦ mkfile(m0, md, m1, content[m, buf]) = ((files ⊕ pcache[datakey(ino, m), mkpentry(true, buf)]) ⊕ icache)[ino], ino ∈ icache ∧ ¬ icache[ino].inode.directory
Proof step 44:
((files ⊕ pcache) ⊕ icache)[ino] = mkfile(m0, md, m1, content), ino ∈ files, ino ∈ icache ⊦ mkfile(m0, md, m1, content[m, buf]) = mkfile (icache[ino].inode.size, icache[ino].inode.meta, icache[ino].inode.nlink, (files ⊕ pcache[datakey(ino, m), mkpentry(true, buf)])[ino].content), icache[ino].inode.directory

Rule argument

spec: <toplevel> name: at-icache-overwrite seq: ⊦ ino ∈ icache ∧ ¬ icache[ino].inode.directory → (files ⊕ icache)[ino] = mkfile (icache[ino].inode.size, icache[ino].inode.meta, icache[ino].inode.nlink, files[ino].content) subst: [ino, icache, files] → [ino, icache, files ⊕ pcache[datakey(ino, m), mkpentry(true, buf)]] flags: <all paths>
