[PATCH] D99977: [GVN] Clear ICF cache when we simplify a value

[Nikita Popov via Phabricator via llvm-commits]

nikic added inline comments.


================
Comment at: llvm/lib/Transforms/Scalar/GVN.cpp:2174
+      // For example, devirtualization to a willreturn function.
+      ICF->clear();
       Changed = true;
----------------
It would be better to extend the IPT interface to allow more fine grained invalidation here. At least to only invalidate the blocks where the user is the current special instruction.
