@fjeremic

fjeremic · 2020-06-15T15:00:58Z

@PushkarBettadpur could you please help take a look at this one? I suspect it is another instance of VICOM emulation not being properly represented in the JIT. We can check with Joe whether this machine was added recently. First step I'd say is to hop on and try and get a reproduction, or run a grinder.

PushkarBettadpur · 2020-06-17T16:07:34Z

Tested this internally over the last few days. A grinder was unable to reproduce the issue, however, based on some of his previous work Rahil suspected that the ETND instruction might be causing issues on some of our systems. However, this instruction doesn't seem to be executed in most of our cases.

Added a JIT-Hack to unilaterally emit an ETND instruction for a recognized method (inlineStringHashCode) and was able to reproduce an illegal instruction failure on these machines.

fjeremic · 2020-06-17T16:32:12Z

Can you print the contents of cat /proc/cpuinfo? Also can you confirm the same tests works on non-SVL machines?

PushkarBettadpur · 2020-06-17T21:37:14Z

Yes, I tried running the test on a non SVL machine and it passes.

fjeremic · 2020-06-18T14:44:36Z

Ok so te is definitely there according to the OS. I see no reason why we would get a SIGILL on ETND instruction, which according to PoPs should only cause problems if the facility is not present. My suspicion is VICOM emulation still.

pshipton · 2020-10-07T20:33:04Z

More internal illegal instruction failures running Java 8 testing, @VermaSh looked at these and associated them with this issue.

Unfortunately, I was unable to reproduce the issue locally on those machines. I believe it's because they have been restarted since the failures were reported. We'll have to wait until the failure resurfaces.

For future reference, here is a unit test to reproduce the failure locally (Thanks to @r30shah):

I launched a grinder and was able to reproduce this on lnxec417.svl.ibm.com and quickly grab core-dumps. It is generating ETND instruction. @VermaSh do you have the unit test you mentioned in #9876 (comment) available to try on?

pshipton · 2022-09-26T20:16:28Z

Another one in the next build on the same machine. I'm disabling the machine for now.

r30shah · 2022-09-26T21:07:24Z

I did try out the unit test we have written in C to reproduce failure, it fails 100%,

j9build@lnxec417 5 13:00:38 /team/rahil# cat test.c
#include <stdio.h>
#include <string.h>
int main()
{
    register unsigned long reg0 asm("0");
    asm volatile(
        ".insn s,0xb2ec0000,0(%1)"
        : "+d" (reg0));
    printf("GPR0 = %llx\n", reg0);
}
j9build@lnxec417 6 13:01:16 /team/rahil# ./a.out
Illegal instruction (core dumped)

VermaSh · 2022-09-27T16:08:10Z

Thanks Rahil for the unit test! My unit test was a JIT hack, unfortunately I don't have that build handy.

It seems to be a VICOM emulation issue. I know our previous VICOM emulation related failure for POPCNT z15 instruction couldn't be fixed because the host machine (z14) simply couldn't support the new mask added on z15. This looks different because Transactional-Execution Facility has been available since zEC12.

I'll try to get some context (a comparison with non-VICOM machine) into why this is failing on VICOM. Hopefully we can take it to the VICOM team for a fix.

VermaSh · 2022-10-18T13:56:30Z

Unfortunately the machine has disappeared. The infra team is looking into the disappearance. internal issue

VermaSh · 2022-10-19T14:18:38Z

The machine is back, but the c unit test no longer fails. We just might have to wait until it starts failing again. To be sure, I am going to get a build with unit test in #9876 (comment)

pshipton · 2022-11-21T21:22:33Z

Another Illegal instruction on lnxec383 which is a better match to #9514, but I'm assuming all the Illegal instruction failures are similar. If this isn't the case let me know.
