Proof step 3 from proof lebsize-pebsize (previous step)

⊦ PAGES_PER_LEB * EB_PAGE_SIZE + 2 * EB_PAGE_SIZE = PEB_SIZE

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 4:
⊦ PEB_SIZE = PAGES_PER_PEB * EB_PAGE_SIZE
Proof step 5:
⊦ PAGES_PER_PEB = PAGES_PER_LEB + 2

Rule argument

spec: <toplevel> name: pebsize seq: ⊦ PEB_SIZE = PAGES_PER_PEB * EB_PAGE_SIZE subst: flags: <all paths>
