Right, the `test/lib/jdk/test/lib/hotspot/ir_framework/tests/` are only tests for the framework itself and should not be run as part of tier testing each time (does not make much sense) but only when the framework is actually modified. Is this still the case when putting them in `test/hotspot/jtreg/testlibrary_tests` (i.e. not executed unless run manually)?

`test/hotspot/jtreg/testlibrary_tests` are seldomly run as part of `:hotspot_misc` test group, yet I don't think it's an issue. the benefit of running testlibrary tests is to gain confidence that the tests which use these libraries are reliable. I'd also disagree that `ir_framework/tests` should be run *only* when the framework is actually, they should also be run when its dependencies are changed, and the framework highly depends on hotspot, so to be sure that the framework didn't get broken after changes in c2, whitebox, etc, you do need run these tests more often.
