Details: - The 'ref99' sandbox was broken by multiple refactorings and internal API changes over the last two years. Rather than try to fix it, I've replaced it with a much simpler version based on var2 of gemmsup. Why not fix the previous implementation? It occurred to me that the old implementation was trying to be a lightly simplified duplication of what exists in the framework. Duplication aside, this sandbox would have worked fine if it had been completely independent of the framework code. The problem was that it was only partially independent, with many function calls calling a function in BLIS rather than a duplicated/simplified version within the sandbox. (And the reason I didn't make it fully independent to begin with was that it seemed unnecessarily duplicative at the time.) Maintaining two versions of the same implementation is problematic for obvious reasons, especially when it wasn't even done properly to begin with. This explains the reimplementation in this commit. The only catch is that the newer implementation is single-threaded only and does not perform any packing on either input matrix (A or B). Basically, it's only meant to be a simple placeholder that shows how you could plug in your own implementation. Thanks to Francisco Igual for reporting this brokenness. - Updated the three reference gemmsup kernels (defined in ref_kernels/3/bli_gemmsup_ref.c) so that they properly handle conjugation of conja and/or conjb. The general storage kernel, which is currently identical to the column-storage kernel, is used in the new ref99 sandbox to provide basic support for all datatypes (including scomplex and dcomplex). - Minor updates to docs/Sandboxes.md, including adding the threading and packing limitations to the Caveats section. - Fixed a comment typo in bli_l3_sup_var1n2m.c (upon which the new sandbox implementation is based).
