… outer Extracts the per-row work of mld_polyvec_matrix_pointwise_montgomery into new _row_eager and _row_lazy helpers. The outer becomes a single mld_polymat-typed K-loop calling the row helper by contract. Drops the lazy/eager outer pair (one outer suffices). This vastly improve CBMC proof performance and also allows to share some more code. Signed-off-by: Matthias J. Kannwischer <matthias@zerorisc.com>
