[PATCH] D45899: TableGen: Add a --write-if-changed flag to tablegen directly instead of doing it in cmake.

[Nico Weber via Phabricator via llvm-commits]

thakis added inline comments.


================
Comment at: lib/TableGen/Main.cpp:113
+      MBOrErr.getError() || std::move(MBOrErr.get())->getBuffer() != Out.str();
+  if (!OutputChanged && WriteIfChanged)
+    return 0;
----------------
Not sure if we should even have a --write-if-changed flag instead of doing this unconditionally, since we always pass the flag.
