+example, LLVM IR passes will emit ``llvm::DiagnosticInfoOptimization*`` that

This sentence is pretty long and complex. Maybe add a full stop instead of the comma and start a new sentence.

+With the only disadvantage being making the code more complex.

----------------
I think the trade-off is clear, but if you really want to be explicit maybe just say at the cost of an extra layer of abstraction.

Comment at: llvm/include/llvm/IR/LLVMContext.h:225
 
-  /// Return the streamer used by the backend to save remark diagnostics. If it
-  /// does not exist, diagnostics are not saved in a file but only emitted via
-  /// the diagnostic handler.
-  RemarkStreamer *getRemarkStreamer();
-  const RemarkStreamer *getRemarkStreamer() const;
-
-  /// Set the diagnostics output used for optimization diagnostics.
-  /// This filename may be embedded in a section for tools to find the
-  /// diagnostics whenever they're needed.
+  /// The "Main remark streamer" used by all the specialized remark streamers.
+  /// This streamer keeps generic remark metadata in memory throughout the life
