Proof step 23 from proof content-trunc (previous step)

n2 < VFS_PAGE_SIZE, n1 < VFS_PAGE_SIZE, n2 + m0 * VFS_PAGE_SIZE < VFS_PAGE_SIZE + VFS_PAGE_SIZE * n0, ¬ m0 * VFS_PAGE_SIZE < n0 * VFS_PAGE_SIZE + n1 ∨ ¬ m0 ∈ content ⊦ (zeropage)[n2] = (m0 ∈ content ⊃ content[m0];zeropage)[n2], n1 = 0

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 24:
n2 < VFS_PAGE_SIZE, n1 < VFS_PAGE_SIZE, n2 + m0 * VFS_PAGE_SIZE < VFS_PAGE_SIZE + VFS_PAGE_SIZE * n0, m0 ∈ content, n0 * VFS_PAGE_SIZE + n1 ≤ m0 * VFS_PAGE_SIZE ⊦ n1 = 0, zero = content[m0][n2]

Rule argument

Additional information

Used simplifier rules: ⊦ m < n ↔ ¬ n ≤ m; (ss)% ⊦ n < VFS_PAGE_SIZE → (zeropage)[n] = zero; (s)
