Description Ben Beasley 2022-01-17 18:01:45 UTC 
Description of problem:
Package opencv fails to build from source in Fedora Rawhide on ppc64le.

Version-Release number of selected component (if applicable):
4.5.5-1.fc36

Steps to Reproduce:
koji build --scratch f36 opencv-4.5.5-1.fc36.src.rpm

Additional info:
This package is tracked by Koschei. See:
https://koschei.fedoraproject.org/package/opencv

On ppc64le only:

> modules/core/include/opencv2/core/vsx_utils.hpp:466:22: error: invalid parameter combination for AltiVec intrinsic '__builtin_vec_sldw'

https://kojipkgs.fedoraproject.org/work/tasks/5024/81355024/build.log

This regression appeared with GCC 12. Unfortunately, it’s also causing dependent packages (e.g. fasttrack, highfive) to FTBFS.

It’s not immediately obvious whether the bug is in OpenCV or in GCC.
