It’s hard to make sense of your pull request. This is the only error I found:
The non-SHA code works for me on 6700K, can you confirm it works on Ryzen?
Yes, all the others I’ve tried so far (except sha256t) work on Ryzen. The changes I made are here:
Edit: I still get the rejects after those changes. I haven’t really dug into it outside of getting it to compile but those changes should have gotten it to work.

Yes, non-sha compiles perfectly.

You could remove the __SHA__ check and compile it with openssl sha256 instead of sph_256. It’ll still run on other hardware just not accelerated.

I was able to mine with a Ryzen 1700X using v3.6.1 on the Xevan algorithm. It worked quite well based on my limited experience with CPU mining. I ran it for 13 1/2 hours and had only 1 rejected share out of 2003 total.
Did you build it from source?
I should have done that before releasing. M7m fails for me using openssl. I have something to work with now.
Excellent! I’m afraid figuring that one out might be far beyond my knowledge.

No I have not been able to figure out how to compile it myself, I used a pre-compiled version from a helpful person via youtube.

SEC Official Pushes Back on Claims Ether Is a Security Ethereum is not a security, says U.S. Securities and Exchange Commission (SEC) director of corporate finance William Hinman. Speaking at the Yahoo! All Markets Summit: […]
Juan Benet and Jesse Clayburgh of Protocol Labs, and Ryan Zurrer of Polychain Capital, discuss CoinList, a platform for token-backed networks to raise money through pre-launch token sales.
While planning the Filecoin token sale, the team at Protocol Labs developed a method of accreditation for US investors in order to comply with securities law. Realising the importance of such a system for the whole ecosystem, they partnered with AngelList to develop this into a platform on which other projects can host their token pre-sales. The end result, CoinList, streamlines the complicated token launch process for developers and investors alike.
By supporting a wide variety of sale mechanics, contracts, and pricing schemes within a standard set of requirements, the platform allows developers to focus on optimising their projects instead of spending time on convoluted compliance processes. Its focus on simplifying due diligence reduces complications for developers while ?’?œfiltering out the signal from the noise?’.
With the ability to clear transactions simultaneously across fiat and cryptocurrencies, and the aim of hosting high-quality and high-integrity projects, CoinList opens up the token ecosystem to an influx of capital from a range of new investors. It gives these investors visibility into the progress of a sale, a clear quality checklist for each token, and a record of their previous investments and the requisite legal agreements.
The significant institutional capital still pushing into the cryptocurrency space highlights the demand for such a versatile yet user-friendly platform at this time. With its solutions to regulatory uncertainty, costly compliance and the current knowledge barrier to investing, CoinList is well-placed to bring in the era of Web 3.0
