As I expect the compiler would do this kind of job as part of optimization, I would suggest moving this <code>if</code> to <a href="https://gitlab.com/gnutls/gnutls/-/merge_requests/1479/diffs#dc3111175f1ef48ddba45e288e07e48088695bdb_1689_1698" data-original="line 1698" data-link="true" data-link-reference="true" data-project="179611" data-merge-request="122158989" data-project-path="gnutls/gnutls" data-iid="1479" data-mr-title="make insecure-hash filter out ciphersuites on ->prf as well" data-reference-type="merge_request" data-container="body" data-placement="top" title="" class="gfm gfm-merge_request">line 1698</a>, as it would be a little clearer why <code>cs.size</code> is checked.</p>
