Commit
This commit does not belong to any branch on this repository, and may belong to a fork outside of the repository.
Adapts the benchmarks added in the `p384` crate in #588 to the `p256` crate, with the goal of using them to measure the performance impact of switching to fiat-crypto's arithmetic implementations.
