Proof step 7 from proof abs-nodes-add-crash-aligned-nodes (previous step)

# buf1 = (y + a ').flashsize, lax0 = [], 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)

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 8:
# buf1 = (y + a ').flashsize, abs-nodes(buf1, # buf0, y + a ', [], false), abs-nodes(buf0, 0, x, lax, false) ⊦ abs-nodes((buf0 + buf1).align↓, 0, x + y + a ', lax, boolvar) ↔ is-aligned(# buf0 + # buf1, EB_PAGE_SIZE)

Rule argument

Additional information

Used simplifier rules: a: ⊦ (lax + lax0) + lax1 = lax + lax0 + lax1; from specification list[laddress-list]% ⊦ lax + [] = lax; (s)
