generic kernel and hard coded optimization, a way to have both about sgminer HOT 7 CLOSED

This could be a useful thing to do as far as efficiency goes, but most probably it's just folk's OpenCL compilers misconfigured (because they are shipped that way), or those optimised kernels built with an improved procedure. Or the kernels using constants/attributes sub-optimally.

This is an option to consider; however, I think we shouldn't introduce another level of complexity if unneded.

P.S. The defines are passed as CompilerOptions in ocl.c, and I don't see why hard-coding them makes a difference.

hard-coding them can help to change the code. for instance operator x%y when y is equal to 8192 can be changed to x&8191 and a lot of transformations like that can be performed. (not sure that one is not captured by the compiler directly)
But i fully agree with you that we shouldn't introduce another level of complexity if it provides slightly the same perf at the end.

I've removed the version from kernel file names, which greatly simplifies kernel change inspection using git diff. As a side effect (along with moving to a separate dir), we don't have to hard-code all available kernel names into the code. Just one "safe default" is enough. This is still done, but is redundant.

With some small modifications, we can allow putting hard-coded .cl files into dir kernel, and just using them by specifying the kernel name in config or on command-line. What needs to be implemented is scanning the dir for what's available and loading it if it's requested by the user.

Sorry if this is hard to parse, I'm a bit busy with a pull request now.

I will not touch it now, i would like to know first if it can improve performance. I try some optimization manually.
If someone has experience on that and can provide feedback, they are welcome.

Working on this in branch kernel-name ATM.
