Description of problem:
This package although being an addon for clang, its naming does not reflect that. In practice that results in users not finding that package from our repos.
Please follow the naming guidelines and name this package to something more appropriate that reflects its role as an addon package of clang:
Secondary you should consider clang to "Recommend" the compiler-rt package as a lot of functionality available there is used during daily development work (asan,ubsan etc).
This bug appears to have been reported against 'rawhide' during the Fedora 26 development cycle.
Changing version to '26'.
compiler-rt has been added as a hard dependency of clang.
