Deduplicate polyw1_pack in multilevel builds by mkannwischer · Pull Request #1142 · pq-code-package/mldsa-native

mkannwischer · 2026-06-02T08:15:25Z

polyw1_pack depends only on GAMMA2, so ML-DSA-65 and -87 use identical code. Move it into the shared poly.c as mld_polyw1_pack_{88,32}, compiled once, with a thin dispatcher in poly_kl.h, so a multilevel build shares a single copy instead of emitting one per parameter set. Split the CBMC proof into per-variant proofs plus a dispatcher proof.

Towards Split up poly_kl.c to reduce code duplication in multilevel build #536

polyw1_pack depends only on GAMMA2, so ML-DSA-65 and -87 use identical code. Move it into the shared poly.c as mld_polyw1_pack_{88,32}, compiled once, with a thin dispatcher in poly_kl.h, so a multilevel build shares a single copy instead of emitting one per parameter set. Split the CBMC proof into per-variant proofs plus a dispatcher proof. - Towards #536 Signed-off-by: Matthias J. Kannwischer <matthias@zerorisc.com>

On aarch64 (the CBMC CI runner) z3 is not stable for this proof: the individual proofs (for reduce_ram mode) runs for over 20 minutes and times out when run in parallel with other proofs. The proof completes in seconds on x86_64, and it also works in non-reduced-ram mode even though this code is indepdendent of it. Alternatives measured on aarch64 (ML-DSA-44, reduce-ram): z3 4.15.3 / 4.16.0 > 20 min bump OBJECT_BITS no effect (still > 20 min) SAT backend ~25 s bitwuzla ~2 min Both SAT and bitwuzla resolve the timeout; use bitwuzla.

@hanno-becker, could you take a look if you agree with the general approach taken here? Then I'll apply the same to the other functions that are currently duplicated in poly_kl.c

hanno-becker

LGTM, but we might use the opportunity to improve some pre-existing yet unclear documentation; see comment.
