Re: qa_volk_32f_8u_polarbutterflypuppet_32f Failed

[Marcus Müller]

Hi Wan,

to answer the most pressing answer first:
No, you should *not* install an older version of GCC (that would be relatively 
involved,
too). The test failing actually only affects you if you plan on using the VOLK 
polar
decoder. Don't think that is the case, since you're not mentioning it.

So, just act as if the test passes. It's very bad it fails, but it shouldn't 
affect you:
you can even disable the failing architecture (AVX2, I guess) for that specific 
kernel and
you would get a kernel that works (according to the unit tests, which might 
themselves be
buggy, but that's a whole different story!).

Best regards,
Marcus
