Details: - Updated the top-level Makefile, build/config.mk.in template, and configure script so that object files corresponding to source files belonging to the BLAS compatibility layer are not compiled (or archived) when the compatibility layer is disabled. (Same for CBLAS.) Thanks to Devin Matthews for suggesting this optimization. - Slight change to the way configure handles internal variables. Instead of converting (overwriting) some, such as enable_blas2blis and enable_cblas, from a "yes" or "no" to a "1" or "0" value, the latter are now stored in new variables that live alongside the originals (with the suffix "_01"). This is convenient since some values need to be sed-substituted into the config.mk.in template, which requires "yes" or "no", while some need to be written to the bli_config.h.in template, which requires "0" or "1". Updated BLIS4 TOMS citation in README.md. Added complex gemm micro-kernels for haswell. Details: - Defined cgemm (3x8) and zgemm (3x4) micro-kernels for haswell-based architectures. As with their real domain brethren, these kernels perfer row storage, (though this doesn't affect most users due to high-level optimizations in most level-3 operations that induce a transpose to whatever storage preference the kernel may have).
