[PATCH] D47306: [llvm-mca] Register listeners with the Stage instances.

[Matt Davis via Phabricator via llvm-commits]

mattd added inline comments.


================
Comment at: tools/llvm-mca/Backend.h:62
   std::set<HWEventListener *> Listeners;
+  llvm::SmallVector<Stage *, 4> Stages;
   unsigned Cycles;
----------------
When we get stages for all of the components in MCA, this will become a unique_ptr<Stage> and we can remove the explicit references to Fetch, Dispatch above.  A pipeline should operates as a  composable sequence of stages.
