Feedback
Benefit to Fedora
This change will not be visible to Fedora end-users, but it will provide some benefits to Fedora packagers:
- Moving some of the brp scripts out of redhat-rpm-config and into c-cxx-rpm-macros means that they won't be run for packages that don't depend on clang or gcc. This will help speed up some builds.
- This will help reduce the review burden of redhat-rpm-config maintainers who aren't interested in C/C++ changes.
Scope
- Proposal owners:
* Create new c-cxx-rpm-macros package and move the relevant content from redhat-rpm-config. * Test the changes.
