[perf][DebugInfo] follow up for "add SectionedAddress to DebugInfo interfaces"

[sylvestre.ledru]

Summary

Fix the build failure when perf jit is enabled

[sylvestre.ledru]

The build is broken with:

Oh I missed perf jit case, excuse me...

Could you set SectionIndex also, please ? The same way how it is done in https://reviews.llvm.org/D58959 :

uint64_t SectionIndex = object::SectionedAddress::UndefSection;
if (auto SectOrErr = Sym.getSection())
  if (*SectOrErr != Obj.section_end())
    SectionIndex = SectOrErr.get()->getIndex();

DILineInfoTable Lines = Context->getLineInfoForAddressRange(
    {*AddrOrErr, SectionIndex}, Size, FileLineInfoKind::AbsoluteFilePath);

[sylvestre.ledru]

Also set SectionIndex

Remove an unrelated change

This looks OK for me(taking into account the comment). Let final approve would be done by David, since He reviewed original patch.
David, Is it OK for you ?

lib/ExecutionEngine/PerfJITEvents/PerfJITEventListener.cpp

270

above two lines are not necessary.

[avl]

Since that is compile time issue - not neccessary to delay it for long time. LGTM.

Friendly ping, @sylvestre.ledru! I'm also experiencing this build error. It looks like other diffs have been submitted to fix this, such as https://reviews.llvm.org/D59162, but it was abandoned in favor of this patch. It'd be great if you could commit this one.

Sorry for the latency, I didn't receive the notification :/

lib/ExecutionEngine/PerfJITEvents/PerfJITEventListener.cpp

       continue;
     }
 
     Expected<uint64_t> AddrOrErr = Sym.getAddress();
     if (!AddrOrErr) {
       consumeError(AddrOrErr.takeError());
       continue;
     }
-    uint64_t Addr = *AddrOrErr;
     uint64_t Size = P.second;
-
+    object::SectionedAddress Address;
+    Address.Address = *AddrOrErr;
     // According to spec debugging info has to come before loading the
     // corresonding code load.
     DILineInfoTable Lines = Context->getLineInfoForAddressRange(
-        Addr, Size, FileLineInfoKind::AbsoluteFilePath);
+        Address, Size, FileLineInfoKind::AbsoluteFilePath);
 
-    NotifyDebug(Addr, Lines);
-    NotifyCode(Name, Addr, Size);
+    NotifyDebug(*AddrOrErr, Lines);
+    NotifyCode(Name, *AddrOrErr, Size);
   }
 
   Dumpstream->flush();
 }
 
 void PerfJITEventListener::notifyFreeingObject(ObjectKey K) {
   // perf currently doesn't have an interface for unloading. But munmap()ing the
   // code section does, so that's ok.
