Moving to ORCv2 - Compiling debuggable code?
Dear Geoff,
As for as ORCv2 is concerned, there is no event listener facility available
as of now.
Thanks

[ORC JIT] Getting symbols from object files before any lookup is done
...odule and an object file before the code is emitted. With the help of Lang I do this now with the lookup function of the Execution Session. Thank you for this!
However, my next issue is: How can I find every defined symbol in my object files? Currently I attached a callback function with the "setNotifyLoaded" function of "RTDyldObjectLinkingLayer". Which is really handy, because I can simply iterate over the symbols of the object files.
However this only works when I already know what is inside my object files, which kinda kills the purpose.
For a workaround I iterate through all the gl...

PerfJITEventListener needs perf-<pid>.map?
I'm trying to use PerfJITEventListener with llvm::orc::LLJITBuilder:
1. perf record -o /tmp/perf.data -- <my_binary_with_event_listener>
2. perf inject -j -v -i /tmp/perf.data -o /tmp/perf.data.jit

[ORC JIT][MLIR] GDBRegistrationListener "second attempt to perform debug registration" assert
...tr->second);
}
LoadedObjInfos.erase(MemMgr);
}
So, where is the registration coming from? Remember that I am on a slightly older version of MLIR. My mlir/lib/ExecutionEngine/ExecutionEngine.cpp has the following code with highlighted debug statement added by me:
objectLayer->setNotifyLoaded(
[engine = engine.get()](
llvm::orc::VModuleKey, const llvm::object::ObjectFile &object,
const llvm::RuntimeDyld::LoadedObjectInfo &objectInfo) {
if (engine->gdbListener) {
uint64_t key = static_cast<uint64_t>(

[ORC JIT][MLIR] GDBRegistrationListener "second attempt to perform debug registration" assert
Hi Adam,
Calls to the listeners should be protected by the RTDyldLayerMutex. Could
you apply the attached patch and share the debugging output from one of the
failing runs?
Regards,
Lang.
