Subject: Re: Unify internal form of mscash2 hashes?
Should be easy, as long as the CPU one gets built for opencl (I think it does).
Do this
in the opencl, drop valid, prepare, split (etc).
in the cpu, rename them to something unique, and remove the static. So valid would be MSCASH2_valid.
Then in opencl, simply do a declaration:
extern int MSCASH2_valid(proper_signature_for_valid);
Then in the format structure for opencl, use MSCAH2_valid.
Done, and one 1 function that ALL of them can use. Now, if the CPU code is not built/linked on the opencl version, then yes, there would need to be some common file.
This (IMHO) is why over zealousness on static-ness (for functions), is not always the best thing. Instances where code sharing SHOULD happen, are often overlooked. Many of the non inner loop format methods could easily be shared, on formats of the same type hashes. Write them correct one time, and then use them.
