hs_err_pid file summary proposal

[Lindenmaier, Goetz]

Hi Coleen,

there is no /proc/cpuinfo on Aix.
Instead, we use the perfstat library to retrieve this information.
https://www-01.ibm.com/support/knowledgecenter/ssw_aix_71/com.ibm.aix.prftools/idprftools_perfstat.htm

Also, the code contains parts to run on PASE / as400.  That's not fully
contributed, but the hooks are in there.  On PASE, libperfstat does
not exist, so we have even another implementation internally...

If you need some more information for the summary I can easily
implement and test that.
So far, I think, the summary contains the same information as 
I can see on x86.

Best regards,
  Goetz.

Hi Coleen,

this is working fine on aix:
http://cr.openjdk.java.net/~goetz/webrevs/8026324-hs_err/hs_err_pid594128.log
I'll have a closer look tomorrow ...

Yes, maybe it's a good idea if you include the patch of pd_print_cpu_info(), 
as it might end up in conflicts.  But I still have to fix the initialization ...

Best regards,
  Goetz.

I've been working on improvements to the hs_err_pid file.  One 
suggestion was to add a summary because some information is hard to find 
in the file, and is very helpful during triaging.   Realizing that 
everyone has their own opinion of the most important information in the 
hs_err_pid file, the summary information is minimal and additive, and 
represents the information that we generally add to the bug report to 
supplement the hs_err_pid file. Also the stack traces have been moved up 
because that's what my opinion of the most important thing is.

This summary proposal can be found in my last 2 comments in bug:

https://bugs.openjdk.java.net/browse/JDK-8026324

There are some samples in the bug report als.

Please reply with comments.  I have implemented this, but this is not an 
RFR yet.

Thanks!
