In comment #9 in the bug 
(https://bugs.launchpad.net/qemu/+bug/1841990/comments/9), I note that the 
issue was produced in running the test suite for the Power Vector Library 
project (https://github.com/open-power-sdk/pveclib), which makes productive use 
of dcbenq.

Maybe that could be adopted or adapted to suit?
