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

# buf1 = (y + a ').flashsize, abs-nodes(buf0, 0, x, lax, false), abs-nodes(buf1, # buf0, y + a ', lax0, false) ⊦ abs-nodes((buf0 + buf1).align↓, 0, x + y + a ', lax + lax0, boolvar) ↔ is-aligned(# buf0 + # buf1, EB_PAGE_SIZE), lax0 = []

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 11:
⊦ lax = [] ↔ ¬(∃ lax0, ladr. lax = lax0 + ladr ')
Proof step 12:
# buf1 = (y + a ').flashsize, abs-nodes(buf1, # buf0, y + a ', lax0, false), abs-nodes(buf0, 0, x, lax, false) ⊦ abs-nodes((buf0 + buf1).align↓, 0, x + y + a ', lax + lax0, boolvar) ↔ is-aligned(# buf0 + # buf1, EB_PAGE_SIZE), ∀ lax1, ladr. lax0 ≠ lax1 + ladr '

Rule argument

spec: list, inst: laddress-list name: lastdiv-rew seq: ⊦ lax = [] ↔ ¬(∃ lax0, ladr. lax = lax0 + ladr ') subst: [lax] → [lax0] flags: <all paths>
