Details:
- Added -mno-tbm -mno-xop -mno-lwp to CKVECFLAGS in bulldozer,
piledriver, steamroller, and excavator configurations to explicitly
disable AMD's bulldozer-era TBM, XOP, and LWP instruction sets in an
attempt to fix the invalid instruction error that has plagued Travis
CI builds since 6a014a3. Thanks to Devin Matthews for pointing out
that the offending instruction was part of TBM (issue #300).
- Restored -O3 to piledriver configuration's COPTFLAGS.
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.)
