(NOT a reviewer) The original instruction used should be dcps1 instead of dpcs1 - there's a misspelling in AArch64 assembler. Could you add a trivial fix to change dpcs1/2/3 to dcps1/2/3?

Oh, I don't know that. I did search dpcs and found nothing. I've filed a new issue about the typo thing: JDK-8244170. Let's resolve it in separated issue.

BTW, how did you test to hit the HaltNode? -- Thanks, Pengfei

I followed Christian and Volkers' recipe on JDK-8230552. Both of them can generate HaltNode. Volker's approach is very interesting. You have to give program a couple of "-XX:SuppressErrorAt=" to increase tolerance.

Thanks, --lx
