Proof step 6 from proof iso-sym (previous step)

files0 ~ files1 ⊦ (ino ∈ files1 ↔ ino ∈ files0) ∧ ( ino ∈ files1 → files1[ino].size = files0[ino].size ∧ files1[ino].meta = files0[ino].meta ∧ files1[ino].nlink = files0[ino].nlink ∧ (λ n. (n / VFS_PAGE_SIZE ∈ files1[ino].content ⊃ files1[ino].content[n / VFS_PAGE_SIZE];zeropage)[n % VFS_PAGE_SIZE]) to files1[ino].size = (λ n. (n / VFS_PAGE_SIZE ∈ files0[ino].content ⊃ files0[ino].content[n / VFS_PAGE_SIZE];zeropage)[n % VFS_PAGE_SIZE]) to files0[ino].size)

Heuristic elimination applied rule insert elim lemma

And obtained the following new goals

Proof step 7:
files1[ino] = mkfile(m, md, m0, content), files0 ~ files1 ⊦ (ino ∈ files1 ↔ ino ∈ files0) ∧ ( ino ∈ files1 → m = files0[ino].size ∧ md = files0[ino].meta ∧ m0 = files0[ino].nlink ∧ (λ n. (n / VFS_PAGE_SIZE ∈ content ⊃ content[n / VFS_PAGE_SIZE];zeropage)[n % VFS_PAGE_SIZE]) to m = (λ n. (n / VFS_PAGE_SIZE ∈ files0[ino].content ⊃ files0[ino].content[n / VFS_PAGE_SIZE];zeropage)[n % VFS_PAGE_SIZE]) to files0[ino].size)

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] → [files1[ino], m, md, m0, 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: files1[ino], m, md, m0, content
