[PATCH] D66377: hwasan: Untag unwound stack frames by wrapping personality functions.

[Evgenii Stepanov via Phabricator via llvm-commits]

eugenis added a comment.

What's the binary size overhead? I assume most of it comes from adding personality functions to noexcept but !nounwind functions?



================
Comment at: llvm/lib/Transforms/Instrumentation/HWAddressSanitizer.cpp:1434
+      if (auto *Pers = dyn_cast<Function>(
+              F.getPersonalityFn()->stripPointerCastsNoFollowAliases()))
+        PersonalityFns[Pers].push_back(&F);
----------------
What if the personality function is an alias or an expression that does not strip down to a function? We could still wrap it.
