Description Mark 2020-06-18 19:12:24 UTC 
SUMMARY
You added AVX-512 support in May (see https://bugs.kde.org/show_bug.cgi?id=383010).  I installed 3.16.0 from source on Ubuntu 18.04; I ran memcheck and callgrind.  My report says "Unrecognised instruction at address 0x55f35ed" at line 286 of my source.  That line is kmovq k7,rax.  The kmovq instruction is part of AVX512BW.  


STEPS TO REPRODUCE

OBSERVED RESULT

EXPECTED RESULT

You are mistaken I'm afraid - the AVX-512 work has not been committed yet.
