First seen in the 4pm OMR acceptance yesterday, which might help narrow down the list of changes. https://ci.eclipse.org/openj9/job/Test_openjdk8_j9_sanity.functional_s390x_linux_xl_OMR_testList_0/6 https://ci.eclipse.org/openj9/job/Test_openjdk8_j9_sanity.functional_s390x_linux_xl_OMR_testList_1/6

@r30shah @harryyu1994 this is a crash in RA:

bin/java -Xjit:vmstate=0x0005ff06 -version
vmState [0x5ff06]: {J9VMSTATE_JIT_CODEGEN} {RegisterAssigning}

There are only three possible changes in the above diff which are Z related and could affect this area. My change affects things during argument mapping which happens right before binary encoding. That leaves the other two changes as the possible culprits. Given this is a blocker on Z we'll need to investigate rather quickly.

@r30shah could you take point on this one and to figure out which change is responsible?

fjeremic commented 4 years ago

The method always seems to be the same across all the jobs I've looked at:

@fjeremic one crash in the functional tests is different. In particular see https://ci.eclipse.org/openj9/job/Test_openjdk8_j9_sanity.functional_s390x_linux_xl_Nightly_testList_0/7

@r30shah I looked into a jitdump from one of the failures [1] and here is what I see of the instructions dumped from the failing state:

This looks related to the instanceof changes in #9517. It makes sense that these failures are only on 64-bit non-compressedrefs JVM which is the only one doing STPQ instructions. I suspect some issue with register pairs or something which we will need a closer look at.

@fjeremic Thanks a lot for limiting down to this. I still have access to machine used for open build. Trying out to see if I can reproduce the issue and see what is wrong there. I think something odd/incorrect I am doing with register pairs used for STPQ instructions.

fjeremic commented 4 years ago

I looked into why jitdump recompilations were not reproducing the issue and it seems it is likely because of #9137. I see OSR trees getting generated on the recompilation but not on the initial compilation. I have a hack test fix for this which I will attempt to see if we can get a proper jitdump recompilation crash.

r30shah commented 4 years ago

@fjeremic I have reproduced this manually. Looking into the instruction it is failing on, it is the Outlined label for instanceOf. Looking into core-dump to see what is wrong.

r30shah commented 4 years ago

I have figured out the issue and also checked the fix with the test locally. Testing the fix with broader test cases again, opening up PR once they are finished.

This one is also different. https://ci.eclipse.org/openj9/job/Test_openjdk11_j9_extended.system_s390x_linux_xl_Nightly/180/ SC_Softmx_Increase_0
