Proof step 6 from proof bufs-log-only-write-lpt-same-flags (previous step)

bleb = buffered(m2), m2 < # lpt, nx ≠ [] ∧ m2 = nx.last ∧ lpt[m2].flags = LP_GROUP_NODES ∨ lpt[m2].flags = LP_INDEX_NODES ⊦ lpt[n, mklp(m, m0, lpt[n].flags, m1)][m2].flags = LP_INDEX_NODES, bleb = nobuffer, nx ≠ [] ∧ m2 = nx.last ∧ lpt[n, mklp(m, m0, lpt[n].flags, m1)][m2].flags = LP_GROUP_NODES

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 7:
m2 < # lpt, nx ≠ [] ∧ m2 = nx.last ∧ lpt[nx.last].flags = LP_GROUP_NODES ∨ lpt[m2].flags = LP_INDEX_NODES ⊦ lpt[n, mklp(m, m0, lpt[n].flags, m1)][m2].flags = LP_INDEX_NODES, nx ≠ [] ∧ m2 = nx.last ∧ lpt[n, mklp(m, m0, lpt[n].flags, m1)][nx.last].flags = LP_GROUP_NODES

Additional information

Used simplifier rules: ⊦ nobuffer ≠ buffered(m); (s)
