Proof step 4 from proof abs-nodes-nospace-header-h (previous step)

x = [], # buf < 2 * NODE_HEADER_SIZE + align↑(m, 2 * NODE_HEADER_SIZE), abs-nodes(buf, n, x, lax, weak), is-encoded(nodeheader(m, boolvar0), subarray(buf, 0, NODE_HEADER_SIZE)), NODE_HEADER_SIZE ≤ # buf ⊦ abs-failed(buf) ∧ x = [] ∧ lax = [] ∧ weak

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 5:
# buf < 2 * NODE_HEADER_SIZE + align↑(m, 2 * NODE_HEADER_SIZE), abs-nodes(buf, n, [], [], weak), is-encoded(nodeheader(m, boolvar0), subarray(buf, 0, NODE_HEADER_SIZE)), NODE_HEADER_SIZE ≤ # buf ⊦ abs-failed(buf) ∧ weak

Rule argument

Additional information

Used simplifier rules: abs-nodes-elems-empty-adr-empty-h: ⊦ abs-nodes(buf, m, [], lax, weak) → lax = [];
