Hi Igor,
In trace.xml:
<struct id="CiMethod">
404 <value type="UTF8" field="class" label="Class name"/>
405 <value type="UTF8" field="method" label="Method name"/>
406 <value type="UTF8" field="signature" label="Method signature"/>
407 </struct>
You don't need to write an individual UTF8 string for every class, method and
desc as we have "intrinsics" for taking care of this for you.
This also means you wouldn't need to create a separate struct, as you can just
define the necessary fields as type METHOD in the CompilerInlining event:
<event id="CompilerInlining" path="vm/compiler/opto/inlining" label="Compiler
Optimization :: Inlining"
410 has_thread="true" is_instant="true">
411 <value type="UINT" field="compileID" label="Compilation ID"
relation="COMP_ID"/>
412 <value type="METHOD" field="caller" label="Caller "/>
413 <value type="METHOD" field="callee" label="Callee "/>
414 <value type="BOOLEAN" field="succeeded" label="Succeeded"/>
415 <value type="UTF8" field="message" label="Message"/>
416 <value type="INTEGER" field="bci" label="bci"/>
417 </event>
// I also removed these attributes " is_requestable="false" is_constant="false"
- they are defaults. I changed to "is_instant=true" since it looks like the
event does not span over a duration in bytecodeInfo.cpp.
At the event site, you will now need to pass the Hotspot Method* as the values
(unsure how you pull that out of a ci* artifact, but you have the Metadata* for
the Method there somewhere):
result.set_caller(Method* caller_method);
result.set_callee(Method* callee_method);
Thanks
Markus

Subject: RFR (S) : 8073607 : add trace events for inlining
Hi guys,
could you please review the patch which adds trace events for inlining for
c1/c2 compiler?
An added event provides information about caller, callee, bci, inline status
and message.
