Arch repo openblas is already built with multiple microarchitecture support through cmake '-DDYNAMIC_ARCH=ON'. https://gitlab.archlinux.org/archlinux/packaging/packages/openblas/ Your PKGBUILD, however, does not seem to enable the same for its build with make. The latter also does not build 64-bit precision libraries, whereas the repo buildscript does. So as of now, the new repo package is superior to this original AUR one, in every aspect that you mentioned. On 3 July 2023 19:11:20 GMT+02:00, Guillaume Horel <guillaume.horel@gmail.com> wrote:
Openblas is a performance oriented package, microarchitecture optimization is exactly what it's about. Moreover this PKGBUILD has different build options than the official one which is allowed by the guidelines.

But this is not a good enough reason to keep PKGBUILDs for the same source in both Arch repo and on AUR.
Arch is not a binary-only distribution: all the build scripts are availabe.
One can always grab a couple of PKGBUILDs from Arch repo's GitLab for fine-tuned, microarchitecture-optimized rebuild, if that is what they want.
But AUR submission guidelines are quite clear: they don't mention allowing duplication for this purpose.

I've responded in the comments that there is nothing broken at the moment with this package, and I don't see the need to delete it.

Same package is now in [extra], named blas-openblas:
https://archlinux.org/packages/extra/x86_64/blas-openblas/
See announcement about it: https://archlinux.org/news/openblas-0323-2-update-requires-manual- intervention/ <https://archlinux.org/news/openblas-0323-2-update-requires-manual-intervention/>
I have notified AUR maintainers in comments about their need to review this change, and possibly adapt their PKGBUILD's.
