Proof step 6 from proof abs-nodes-aligned-2headersize-mod (previous step)

EB_PAGE_SIZE = n + # buf % EB_PAGE_SIZE, abs-nodes(buf, 0, x, lax, false), is-aligned(n + # buf % EB_PAGE_SIZE, 2 * NODE_HEADER_SIZE) ⊦ is-aligned(n, 2 * NODE_HEADER_SIZE)

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 7:
m ≠ 0, is-aligned(n1, m) ⊦ is-aligned(n0 + n1, m) ↔ is-aligned(n0, m)
Proof step 8:
EB_PAGE_SIZE = n + # buf % EB_PAGE_SIZE, abs-nodes(buf, 0, x, lax, false), is-aligned(n + # buf % EB_PAGE_SIZE, 2 * NODE_HEADER_SIZE) ⊦ is-aligned(n, 2 * NODE_HEADER_SIZE), 2 * NODE_HEADER_SIZE ≠ 0 ∧ is-aligned(# buf % EB_PAGE_SIZE, 2 * NODE_HEADER_SIZE)

Rule argument

spec: align name: is-aligned-add seq: m ≠ 0, is-aligned(n1, m) ⊦ is-aligned(n0 + n1, m) ↔ is-aligned(n0, m) subst: [m, n1, n0] → [2 * NODE_HEADER_SIZE, # buf % EB_PAGE_SIZE, n] flags: <all paths>

Additional information

Used terms: 2 * NODE_HEADER_SIZE, # buf % EB_PAGE_SIZE, n
