AssertionError in CPUFeatures.X64::<clinit> with -XX:MaxVectorSize=32

XMLWordPrintable

    • x86

      assert SUPPORTS_AVX512F == (VectorShape.getMaxVectorBitSize(int.class) == 512);

      This assert fails if we run the VM with -XX:MaxVectorSize=32

      Note that in the future with AVX-10, I think having AVX512F but MaxVectorSize == 32 would likely be the default settings on many hardware.

      Similar assertions in the same file can trigger for similar reasons, too.
