Proof step 7 from proof abs-nodes-nospace-header-h (previous step)

# buf < 2 * NODE_HEADER_SIZE + align↑(m, 2 * NODE_HEADER_SIZE), is-encoded(nodeheader(m, boolvar0), subarray(buf, 0, NODE_HEADER_SIZE)), NODE_HEADER_SIZE ≤ # buf, # buf = 0 ∧ [] = [] ∨ (∃ buf0, buf1. buf = buf0 + buf1 ∧ abs-padding(buf0) ∧ abs-nodes(buf1, n + # buf0, [], [], weak)) ∨ weak ∧ abs-failed(buf) ∧ [] = [] ⊦ abs-failed(buf) ∧ weak

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 8:
# buf < 2 * NODE_HEADER_SIZE + align↑(m, 2 * NODE_HEADER_SIZE), is-encoded(nodeheader(m, boolvar0), subarray(buf, 0, NODE_HEADER_SIZE)), NODE_HEADER_SIZE ≤ # buf, weak ∧ abs-failed(buf) ∨ buf = buf0 + buf1 ∧ abs-padding(buf0) ∧ abs-nodes(buf1, n + # buf0, [], [], weak) ⊦ buf = mkbuf(0), abs-failed(buf) ∧ weak

Additional information

Used simplifier rules: ⊦ NODE_HEADER_SIZE ≠ 0; (s)% ⊦ m ≤ 0 ↔ m = 0; (s)% ⊦ # mkbuf(n) = n; (s)% ⊦ # buf = 0 ↔ buf = mkbuf(0); (s)
