Details:
- Implemented assembly-based packm kernels for single- and double-
precision complex domain (c and z) and housed them in the 'haswell'
kernel set. This means c3xk, c8xk, z3xk, and z4xk are now all
optimized.
- Registered the aforementioned packm kernels in the haswell, zen,
and zen2 subconfigs.
- Minor modifications to the corresponding s and d packm kernels that
were introduced in 426ad67.
- Thanks to AMD, who originally contributed the double-precision real
packm kernels (d6xk and d8xk), upon which these complex kernels are
partially based.
For more information on sub-configurations and configuration families in BLIS, please read the Configuration Guide, which can be viewed in markdown-rendered form from the BLIS wiki page.
If you don't have time, or are impatient, take a look at the config_registry
file in the top-level directory of the BLIS distribution. It contains a
grammar-like mapping of configuration names, or families, to sub-configurations,
which may be other families. Keep in mind that the / notation:
<config>: <config>/<name>
means that the kernel set associated with <name> should be made available to
the configuration <config> if <config> is targeted at configure-time.
(Some configurations borrow kernels from other configurations, and this is how
we specify that requirement.)
