Eliminate use_hint 32/88 intrinsics by willieyz · Pull Request #940 · pq-code-package/mldsa-native

Resolves: AVX2: Replace intrinsics implementation of poly_use_hint with assembly #484
In this PR, we replace the AVX2 intrinsics implementation of poly_use_hint_32 and poly_use_hint_88 with a x86_64 assembly version, this is part of the effort to enable HOL-Light proofs.

We also tried unrolling the loops: mld_poly_use_hint_88_avx2_loop and mld_poly_use_hint_32_avx2_loop
in both files. However, the benchmark results showed that this did not provide any performance benefit, so we decided to keep the current version.

This commit adds poly_use_hint to bench --components for benchmarking the performance impact of the changes to: - poly_use_hint_32 - poly_use_hint_88 Signed-off-by: willieyz <willie.zhao@chelpis.com>

In this PR, we replace the AVX2 intrinsics implementation of poly_use_hint_32 and poly_use_hint_88 with a x86_64 assembly version, this is part of the effort to enable HOL-Light proofs. Signed-off-by: willieyz <willie.zhao@chelpis.com>
