Proof step 43 from proof write-inode-inv (previous step)

files1[ino] = mkfile(m, md, m1, content), write-inv(0, n1, mkinode(ino, md, false, m1, 0, m0), buf, n, dirs, files0, files1), ino ∈ files1, ⌊err0⌋ ⊦ [if err0 = ESUCCESS then files0[ino].size := m0 + n] write-inv(0, n1, mkinode(ino, md, false, m1, 0, files0[ino].size), buf, n, dirs, files0, files1)

Heuristic symbolic execution applied rule if negative right

And obtained the following new goals

Proof step 44:
files1[ino] = mkfile(m, md, m1, content), write-inv(0, n1, mkinode(ino, md, false, m1, 0, m0), buf, n, dirs, files0, files1), ino ∈ files1, ⌊err0⌋ ⊦ [skip] write-inv(0, n1, mkinode(ino, md, false, m1, 0, files0[ino].size), buf, n, dirs, files0, files1)

Rule argument

pos: right 1

Additional information

Used simplifier rules: ⊦ ⌊err⌋ → err ≠ ESUCCESS; (s)
