[jira] Updated: (HARMONY-5590) [drlvm][port] Move
signals/exceptions handling and crash handling to the Port
Posted by "Ilya Berezhniuk (JIRA)" <ji...@apache.org>.
[ https://issues.apache.org/jira/browse/HARMONY-5590?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Ilya Berezhniuk updated HARMONY-5590:
-------------------------------------
Attachment: 0002-Move-signal-and-crash-handling-to-the-Port-to-be-use.patch
0001-move-Moving-to-PORT-memory-access-stack-dump.patch
Here are the updated patches.
These patches are merged with latest changes and include an implementation of VM callback for stack iteration, and also include some bugfixes and improvements.
With these patches I've got correct stack traces for interpreter and JIT (for inlined methods too), except the first 4 native functions from launcher - it looks like line information was disabled in classlibb for release build.
I've started pre-commit testing just to be sure. I'll report the results soon.

Ilya Berezhniuk commented on HARMONY-5590:
------------------------------------------
All the pre-commit tests have passed on Linux/Windows x86/x86_64.
Linux/ia64 still can't be built, so I can't check it.

[jira] Updated: (HARMONY-5590) [drlvm][port] Move
signals/exceptions handling and crash handling to the Port
Posted by "Ilya Berezhniuk (JIRA)" <ji...@apache.org>.
[ https://issues.apache.org/jira/browse/HARMONY-5590?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Ilya Berezhniuk updated HARMONY-5590:
-------------------------------------
Attachment: 0002-Move-signal-and-crash-handling-to-the-Port-to-be-use.patch
0001-move-Moving-to-PORT-memory-access-stack-dump.patch
I've moved signal and crash handling to the Port onto the new signal/crash handling interfaces.
Additionally this included:
- moving memory access functions and breakpoints instrumentation to the Port;
- moving native stack unwinding to the Port;
- moving mutex implementation from the Hythread to the Port;
The patches suggested were build over r634360; pre-commit tests are passed on Windows/Linux x86/x86_64, and Linux/ia64/interpreter.
Known problems:
1) these patches should be merged with latest canges, specifically with r634547 and r634569
2) crash stack now contains native functions only; Java unwinding VM callback is not implemented yet
3) to work properly, the Port should become shared library (to avoid static vars duplication etc.)
I'm going to perform tasks 1) - 3) soon, then I'll update the patches.
