[PATCH] D38768: Add remarks describing when a pass changes the IR instruction count of a module

[Eli Friedman via Phabricator via llvm-commits]

efriedma added inline comments.


================
Comment at: lib/IR/Function.cpp:200
+  for (BasicBlock &BB : BasicBlocks)
+    NumInstrs += BB.size();
+  return NumInstrs;
----------------
Should we use `std::distance(BB.instructionsWithoutDebug.begin(), BB.instructionsWithoutDebug().end())` instead, so the numbers are consistent whether or not debug info is enabled?
