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
