%description -n hipcc
hipcc is a compiler driver utility that will call clang or nvcc, depending on
target, and pass the appropriate include and library options for the target
compiler and HIP infrastructure.

hipcc will pass-through options to the target compiler. The tools calling hipcc
must ensure the compiler options are appropriate for the target compiler.
