Hi David,
Thanks and apologies.
No apology needed :)
This issue was discovered by a broad -Xcomp testing with jtreg on
Loongson CPUs (MIPS compatible processors).
It was intended to test our MIPS port of OpenJDK.
We've found and fixed quite a lot of JIT bugs for our MIPS
implementation by this approach.
Okay, you may well be testing more tests under Xcomp than what we
regularly do, so that may well expose a number of tests that may not
work at all, or which fail intermittently. I'm trying to find out if
there is a relatively easy way to enumerate the tests we do run under
-Xcomp.
No easy way but I can tell you we only run a subset of tests in
java/lang, java/math and java/util under -Xcomp.

I'll ask Ao Qi to file a bug on JBS and post a webrev soon.
Thanks again.
Best regards,

For hotspot testing we have certain sets of tests that are run under
-Xcomp, but this is obviously not one of them. Did you discover this
by chance or because you are attempting to do broad -Xcomp testing?
Not every test will work with Xcomp (for various reasons) and we
aren't actively trying to make every test pass with Xcomp.
But by all means file a bug and fix it.
Cheers,
David
