    Description

      I ran the following tests with extra compiler flags:
      -XX:+IgnoreUnrecognizedVMOptions -XX:-MonomorphicArrayCheck -XX:-UncommonNullCast

      So far only seen it on aarch64 (linux / macosx)

      jdk/incubator/vector/Float512VectorTests.java
      jdk/incubator/vector/Vector128ConversionTests.java
      jdk/incubator/vector/VectorMaxConversionTests.java

      Error mixing types: vectorx[4]:{float_top} and float_top
