I started a 20x Grinder job on AArch64 Linux (internal job/Grinder/30827), but it seems it takes nearly an hour for running jdk_vector_1. The job might be killed by timeout after 20 hours.

knn-k · 2023-02-02T01:36:09Z

2 failures out of 18 iterations in the Grinder job above.
Both of them are "Misaligned stack-allocated object in thread MainThread" in jdk/incubator/vector/Int64VectorTests.java.

It is unclear at this point if the failures are related to vector implementation or not.

knn-k · 2023-02-02T06:57:06Z

I ran Int64VectorTests.java on AArch64 Linux in my environment, using the binary from #16510 (comment).
I got no failures from running it 80 times.

knn-k · 2023-02-02T10:41:14Z

From the jdmpview "info jitm" output:

start=0xffff696766c4  end=0xffff69677db8   Int64VectorTests::EQInt64VectorTestsMasked(Ljava/util/function/IntFunction;Ljava/util/function/IntFunction;Ljava/util/function/IntFunction;)V

There are two versions of JIT generated code for this method.
The first one is smaller than 6KB, while the second one is over 100 KB. "pc = 0x0000FFFF696A44EC" is in the address range of the second one.

knn-k · 2023-03-12T23:54:00Z

I ran jdk_vector_1 on AArch64 Linux in my environment 20 times, and got no test failures.
A 20x Grinder job (job/Grinder/31519/) on AArch64 macOS generated one failure.

knn-k · 2023-03-13T05:09:46Z

I ran 3x20 Grinder jobs on AArch64 macOS (31570, 31571, 31573) with the following option to take the JIT trace file, but I was not able to reproduce the failure.

-Xjit:{Int64VectorTests.EQInt64VectorTestsMasked*}(traceFull,log=eqInt64.txt)

knn-k · 2023-03-14T00:42:28Z

Another Grinder job (31579) fails with a different Java method, Byte256Vector.rearrange() in VectorMaxConversionTests.

In both cases, "O-Slot value" points to an address in the stack near the "O-Slot" value, but the distance ("O-Slot" - "O-Slot value") is different.

I don't think it guarantees anything, but I got no failures in 3x20 Grinder jobs with the -Xjit:disableEscapeAnalysis option.

No failures.

As this is an intermittent failure only seen in an incubator feature this should not hold up 0.38. Moving out to 0.40.

PR #17825 has been merged.
Let's see how it goes with other tests with misaligned object in the stack.
