Yes. In the extreme version of single platform LTO, we would bake one device-info stanza for every subplatform. That may be a little overkill (or rather too complicated for the user to know and too fine-grained to be useful). So the middle ground is that we have subplatform in the runtime_info, and the compiler has to do two loads. We can still benefit from using BIT() though. -Chris _______________________________________________ Intel-gfx mailing list Intelfirstname.lastname@example.org https://lists.freedesktop.org/mailman/listinfo/intel-gfx
