Proof step 11 from proof abs-nodes-nospace-h (previous step)

x = nd + x0, # buf < NODE_HEADER_SIZE ⊦ abs-nodes(buf, m, x, lax, boolvar) ↔ x = [] ∧ lax = [] ∧ buf = mkbuf(0)

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 12:
# buf < NODE_HEADER_SIZE, abs-nodes(buf, m, nd ' + x0, lax, boolvar) ⊦

Rule argument

Additional information

Used simplifier rules: a: ⊦ (x + y) + z = x + y + z; from specification list% ⊦ a ' + x ≠ []; (s)% ⊦ a + x = a ' + x; (s)
