Proof step 27 from proof write-loop-err (previous step)

VFS_PAGE_SIZE = n0 + (ino2 + ino0) % VFS_PAGE_SIZE, err = ESUCCESS, min(ino1 - ino2 + ino0, n0) ≠ 0, (ino2 + ino0) / VFS_PAGE_SIZE ∈ files[inode.ino].content, inode.ino ∈ files, ino2 + ino0 ≤ ino1 ⊦ [afs_check_commit#(dirs, files; err; asynced); if err = ESUCCESS then {buf := copy(buf0, ino0, files[inode.ino].content[(ino2 + ino0) / VFS_PAGE_SIZE], (ino2 + ino0) % VFS_PAGE_SIZE, min(ino1 - ino2 + ino0, n0)); afs_writepage#(inode, (ino2 + ino0) / VFS_PAGE_SIZE, buf, dirs; err, files; asynced)}; if err = ESUCCESS then ino3 := ino0 + min(ino1 - ino2 + ino0, n0)] (err = ESUCCESS ∨ ⌊err⌋ )

Heuristic elimination applied rule insert elim lemma

And obtained the following new goals

Rule argument

spec: inode name: elim seq: ⊦ ( ( ( (m = inode.ino ∧ md = inode.meta) ∧ (boolvar ↔ inode.directory)) ∧ m0 = inode.nlink) ∧ m1 = inode.nsubdirs) ∧ m2 = inode.size ↔ inode = mkinode(m, md, boolvar, m0, m1, m2) subst: [inode, m, md, boolvar, m0, m1, m2] → [inode, m, md, boolvar, m0, m1, m2]

Additional information

Used simplifier rules: ⊦ ( ( ( (m = inode.ino ∧ md = inode.meta) ∧ (boolvar ↔ inode.directory)) ∧ m0 = inode.nlink) ∧ m1 = inode.nsubdirs) ∧ m2 = inode.size ↔ inode = mkinode(m, md, boolvar, m0, m1, m2); (elim) Used terms: inode, m, md, boolvar, m0, m1, m2
