[PATCH] D69676: [WinCFG] Handle constant casts carefully in .gfids emission

[Eli Friedman via Phabricator via llvm-commits]

efriedma added a comment.

I mentioned this on the bug, but do we care if a reference to a function is optimized away at the MIR level?



================
Comment at: llvm/lib/CodeGen/AsmPrinter/WinCFGuard.cpp:71
+        // constants, such as vtable initializers, to escape the function.
+        if (C->stripPointerCasts() == FnOrCast)
+          Users.push_back(FnUser);
----------------
Does stripPointerCasts do the right thing here?  It can look through multiple levels of casts.
