Build opencv-4.11.0 on Fedora rawhide fails only on PPC64LE with new GCC 15 #26770
Description
System Information
OpenCV: 4.11.0
Operating System / Platform Fedora rawhide (42)
Compiler & compiler version: gcc: 15.0.0-0.4.fc42
here is the scratch build (only available for a few days) : https://koji.fedoraproject.org/koji/taskinfo?taskID=127846000
"
See https://gcc.gnu.org/r15-1919 and
https://gcc.gnu.org/pipermail/gcc-patches/2024-April/649747.html
In short, for intrinsics on the various architectures, the supported API
are the intrinsics declared in the header, not the underlying builtin
functions, which can be added/removed as needed, those are just
implementation details how to implement those intrinsics.
opencv is clearly using a builtin directly, don't.
That said, I don't know much about the VSX intrinsics, for vector
conversions there is also __builtin_convertvector (both in GCC and LLVM)
which allows to say convert a vector of floats to vector of doubles or vice
versa.
In any case, I think raise this upstream and if they don't know what to do,
get them talk to the author of those changes.

Steps to reproduce
git clone https://src.fedoraproject.org/forks/packit/rpms/opencv.git
git checkout rawhide-update-pull_from_upstream
fedpkg --release rawhide scratch-build --target f42-build-side-103300 (this one one need to be a fedora packager ) you can build locally with koji side-tag f42-build-side-1103300 repo, let me know if you need that instructions
Thank you
Issue submission checklist
- I report the issue, it's not a question
- I checked the problem with documentation, FAQ, open issues, forum.opencv.org, Stack Overflow, etc and have not found any solution
- I updated to the latest OpenCV version and the issue is still there
- There is reproducer code and related data files (videos, images, onnx, etc)
