Look at https://github.com/openssl/openssl/pull/5320 to get an example. It’s about safety and maintainability.

Maybe it is negligible, but there is a cost. * The build rules are more complicated; we have had errors with .S vs .s files * There are more internal config parameters to understand * There are more ifdefs in the code * There’s only one person who really understands the perlasm stuff I think “significant maintenance cost” is not the question to ask. It’s maintenance and risk versus use.

We should remove the assembler versions of the following Blowfish, cast, des, rc4, rc5, ripemd, whirlpool, md5 The reason is that they are outdated, not in use very much, and optimization is not important, compared to having a single reference source that we can maintain and debug. _______________________________________________ openssl-project mailing list openssl-project@openssl.org<mailto:openssl-project@openssl.org> https://mta.openssl.org/mailman/listinfo/openssl-project<https://urldefense.proofpoint.com/v2/url?u=https-3A__mta.openssl.org_mailman_listinfo_openssl-2Dproject&d=DwMFaQ&c=96ZbZZcaMF4w0F4jpN6LZg&r=4LM0GbR0h9Fvx86FtsKI-w&m=47KNj5EcM4J5bu7SggXsMIQAazYObKX2PjUtZ71Dl3U&s=fh1Zx5a9eDRlRkP-mVoUh5Wl49tdWCb5J3UpjZNMuR4&e=>
