Yeah, sorry. Here's a proper engineered variant. I don't expect that

The following avoids registering unsupported GCN offload devices
when iterating over available ones. With a Zen4 desktop CPU
you will have an IGPU (unspported) which will otherwise be made
available. This causes testcases like
libgomp.c-c++-common/non-rect-loop-1.c which iterate over all
