Proof step 26 from proof writepage-afs-cons (previous step)

# buf2 = VFS_PAGE_SIZE, afs-cons(dirs, files), m ∈ files, ino0 + n ≤ # buf0, ino + n ≤ VFS_PAGE_SIZE ⊦ afs-cons(dirs, files[m, files[m].content:= files[m].content[pageno, copy(buf0, ino0, buf2, ino, n)]])

Heuristic elimination applied rule insert elim lemma

And obtained the following new goals

Proof step 27:
# buf2 = VFS_PAGE_SIZE, files[m] = mkfile(m0, md, m1, content), afs-cons(dirs, files), m ∈ files, ino + n ≤ VFS_PAGE_SIZE, ino0 + n ≤ # buf0 ⊦ afs-cons(dirs, files[m, files[m].content:= content[pageno, copy(buf0, ino0, buf2, ino, n)]])

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[m], m0, md, m1, 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[m], m0, md, m1, content
