This can be achieved by using `applyIfCPUFeature` annotations in the IR checks, similarly to e.g. `test/hotspot/jtreg/compiler/loopopts/superword/RedTest_int.java`. I recognize this limitation is pre-existing, but this issue seems a good place to address it.

Thanks Roberto, it sounds reasonable to diverge from the original test and make it modular instead of sticking with the bulk test. I'll propose a new updated version. I'll also have a look at which jtreg `@requires` I can replace with IR framework annotations.
