Proof step 31 from proof abs-padding-abs-nodes-h (previous step)

# buf2 = nd.alignedsize + 2 * NODE_HEADER_SIZE, # buf1 = NODE_HEADER_SIZE, buf1 + buf0 + validtrailer = buf2 + buf, ladr = @(m, # buf2), lax = ladr + lax0, abs-node(buf2, nd), abs-nodes(buf, m + # buf2, x0, lax0, weak), is-aligned(# buf0, 2 * NODE_HEADER_SIZE), is-encoded(nodeheader(# buf0, true), buf1) ⊦ lax = []

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 32:
# buf1 = NODE_HEADER_SIZE, # buf2 = nd.alignedsize + 2 * NODE_HEADER_SIZE, buf1 + buf0 + validtrailer = buf2 + buf, abs-node(buf2, nd), abs-nodes(buf, m + # buf2, x0, lax0, weak), is-aligned(# buf0, 2 * NODE_HEADER_SIZE), is-encoded(nodeheader(# buf0, true), buf1) ⊦

Additional information

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