   CGOpenMPOutlinedRegionInfo CGInfo(*CS, ThreadIDVar, CodeGen, InnermostKind,
                                     HasCancel, OutlinedHelperName);
   CodeGenFunction::CGCapturedStmtRAII CapInfoRAII(CGF, &CGInfo);
+  llvm::Function *Fn = CGF.GenerateOpenMPCapturedStmtFunction(*CS);

You can check for `OMPBuilder` in the constructor/destructor.


================
Comment at: llvm/include/llvm/Frontend/OpenMPIRBuilder.h:69-71
+  void pushFinalizationCB(FinalizationInfo &&FI) {
+    FinalizationStack.emplace_back(std::move(FI));
+  }

You can use it in `emplace` version while `push...` function will rely on copy semantics.
