Advice needed. This software is clearly x86-only (the required SSE2 does not exist on any other architecture) and as such should be ExclusiveArch. Whether you should make it ExclusiveArch: x86_64 or whether you should also enable 32-bit x86 is up for debate. It is the usual issue of upstream not supporting non-SSE2 CPUs. Fedora i686 packages are supposed to work without SSE2 (in fact, without ANY vector instructions, even MMX and SSE), but it is nicer to the users to have the software available for some 32-bit x86 CPUs than for none at all. But either way, it clearly does not make sense to enumerate all the non-x86 architectures in ExcludeArch, ExclusiveArch is the right concept.
