[Clement Courbet via Phabricator via llvm-commits]

courbet added inline comments.


================
Comment at: llvm/tools/llvm-exegesis/lib/X86/X86Counter.cpp:178
+  const void *To = nullptr;
+  if (!FunctionBytes.empty()) {
+    From = reinterpret_cast<const void *>(FunctionBytes.data());
----------------
Let's return an error when `FunctionBytes.empty()`. Right now this will assert later.
