[jira] Created: (HARMONY-2145) [drlvm][jvmti] Compiled Method Load
event - inlined method support
[drlvm][jvmti] Compiled Method Load event - inlined method support
------------------------------------------------------------------
Key: HARMONY-2145
URL: http://issues.apache.org/jira/browse/HARMONY-2145
Project: Harmony
Issue Type: New Feature
Components: DRLVM
Reporter: Eugene S. Ostrovsky
Current VM doesn't report Compiled Method Load event for methods that are inlined by JIT.
Though spec requires it to be sent for every compiled method:
http://java.sun.com/j2se/1.5.0/docs/guide/jvmti/jvmti.html#CompiledMethodLoad
We need to add some function to interface between VM and JIT in order to let VM know about inlined methods.

[jira] Updated: (HARMONY-2145) [drlvm][jvmti] Compiled Method Load
event - inlined method support
Posted by "George Timoshenko (JIRA)" <ji...@apache.org>.
[ http://issues.apache.org/jira/browse/HARMONY-2145?page=all ]
George Timoshenko updated HARMONY-2145:
---------------------------------------
Attachment: exe_notify_compile_method_load_added.diff
There is already some implementation of required functionality.
The patch appends exe_notify_compile_method_load flag into the OpenMethodExecutionParam struct (FALSE by default).
When the flag is turned on code emitter (Jitrino OPT) runs sendCompiledMethodLoadEvent for each method that was compiled during current compilation session.
Here is the current implementation of sendCompiledMethodLoadEvent (in DrlVMInterface.cpp):
void DrlVMCompilationInterface::sendCompiledMethodLoadEvent(MethodDesc * methodDesc,
uint32 codeSize, void* codeAddr, uint32 mapLength,
AddrLocation* addrLocationMap, void* compileInfo) {
// VM-JIT interface function should be called here instead of logging
if (Log::isEnabled()) {
Log::out() << " ** Inlined method: "
<< methodDesc->getName() << std::endl;
Log::out() << " ** Number of locations:" << mapLength
<< std::endl;
}
}
sendCompiledMethodLoadEvent 's signature AFAIU is exactly the same as the one from SPEC.
So all we need IMO is to insert into sendCompiledMethodLoadEvent a call to VM that raises necessary event.
