Proof step 20 from proof prepost-write-superblock (previous step)

# buf0 = encoding-size(sb, EB_PAGE_SIZE), ebm-vol-inv(avol), is-encoded(sb, buf0), encoding-size(sb, EB_PAGE_SIZE) ≤ LEB_SIZE ⊦ # avol = 0, is-aligned(encoding-size(sb, EB_PAGE_SIZE), EB_PAGE_SIZE)

User applied rule insert rewrite lemma

And obtained the following new goals

Rule argument

spec: encoding-aligned, inst: encoding-superblock name: size-aligned seq: ⊦ encoding-size(sb, m) = align↑(encoding-size-unaligned(sb), m) subst: [m, sb] → [EB_PAGE_SIZE, sb] flags: <all paths>

Additional information

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