Proof step 10 from proof abs-nodes-crash (previous step)

abs-nodes(buf, 0, x, lax, true) ⊦ is-aligned(align↓(# buf, EB_PAGE_SIZE), NODE_HEADER_SIZE), ∃ x0, lax0. x0 ⊑ x ∧ lax0 ⊑ lax ∧ abs-nodes(subarray(buf, 0, align↓(# buf, EB_PAGE_SIZE)), 0, x0, lax0, true)

User applied rule insert rewrite lemma

And obtained the following new goals

Rule argument

spec: node-header-size name: is-aligned-pagesize-imp-headersize seq: ⊦ is-aligned(n, EB_PAGE_SIZE) → is-aligned(n, NODE_HEADER_SIZE) subst: [n] → [align↓(# buf, EB_PAGE_SIZE)] flags: <all paths>

Additional information

Used simplifier rules: ⊦ EB_PAGE_SIZE ≠ 0; (s)%m ≠ 0 ⊦ is-aligned(align↓(n, m), m); (s) Used terms: align↓(# buf, EB_PAGE_SIZE)
