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.
- Other developers: N/A
- Release engineering: #Releng issue number
- Policies and guidelines: N/A (not needed for this Change)
- Trademark approval: N/A (not needed for this Change)
- Alignment with Objectives:
Upgrade/compatibility impact
How To Test
These changes will be tested by doing test builds of a sampling of Fedora packages.
