> @missa-prime Looks like an interesting patch! Do you think you could add some sort of IR test here, to verify that the correct code is generated on AVX10 vs lower AVX?

@eme64 Thanks for the suggestion. This patch doesn't modify any IR though, so I'm not sure what IR test(s) to add. I could modify existing tests (`test/hotspot/jtreg/compiler/vectorapi/VectorFPtoIntCastTest.java`, `test/hotspot/jtreg/compiler/vectorization/TestFloatConversionsVector.java`, `test/hotspot/jtreg/compiler/vectorization/runner/ArrayTypeConvertTest.java`) that use IR nodes as dependencies though. Would that be sufficient? Or did you have something else in mind?
