It looks like there are 3 primary files related to this issue, in both master 
and next (found via "grep -inr xgetbv ." from the top-level source directory of 
each):

volk/tmpl/volk_cpu.tmpl.c
volk/gen/archs.xml
volk/lib/CMakeLists.txt

and, these are about the same between those 2 branches.  So, not sure to what 
changes you're referring, but in my reading they don't seem to impact this 
particular issue significantly. - MLD

BTW> Supposedly Qt does both configure-time and runtime detection and handling 
of AVX (as well as SSE 1/2/3/4 and so forth).  I know of their configure-time 
parameters (handled in QMake), but I'm not aware of their runtime system.  
Might be worth investigating.
