> @JohnTortugo, thank you for adding new test. But it would be nice also add additional run with `-XX:+IgnoreUnrecognizedVMOptions -XX:-UseCompressedClassPointers` to failed test `test/hotspot/jtreg/compiler/c2/irTests/scalarReplacement/AllocationMergesTests.java`
 
Actually `-XX:+IgnoreUnrecognizedVMOptions` is not needed because you require `vm.bits == 64` in the test.
