Make poly_use_hint destructive by mkannwischer · Pull Request #1070 · pq-code-package/mldsa-native

mkannwischer · 2026-04-29T05:41:13Z

Rework mld_poly_use_hint, its native dispatchers, the underlying
aarch64/x86_64 implementations, and the polyveck wrapper from
(b, a, h) to in-place (b, a) where b holds the hint polynomial on
entry and the corrected high bits on exit — i.e. the first output
and second input now share a buffer.

This will enable reducing memory consumption in #1007.

Depends on CBMC: Add contracts and proofs for yvec init/get_poly #1066
Depends on Make poly_pointwise_montgomery destructive #1067
Depends on HOL-Light: Add HOL Light poly_use_hint proofs for AArch64 #1037

LGTM, thank you @mkannwischer

Rework mld_poly_use_hint, its native dispatchers, the underlying aarch64/x86_64 implementations, and the polyveck wrapper from (b, a, h) to in-place (a, h): the high bits of a are corrected in place using hint h, rather than written to a separate output buffer. Signed-off-by: Matthias J. Kannwischer <matthias@zerorisc.com>
