Not systematically. We have some IR testing for more complex areas, located under `test/hotspot/jtreg/compiler/vectorapi/`. When we started out testing there was no IR testing framework so we relied on classic unit tests running a test N times for C2 to kick in. That is still the case for the majority of tests. It would be nice to have a better balance, and a way to systematically generate IR tests for the various vector operations. ------------- PR Comment: https://git.openjdk.org/jdk/pull/20507#issuecomment-2415212261
