[cfe-users] Replacement for -fdevirtualize?

[Jeffrey Walton via cfe-users]

Hi Everyone,

I'm catching a warning when trying to use -fdevirtualize under Clang.

  $ make
  /usr/local/bin/clang++ -DNDEBUG -g -O2 -fdevirtualize -march=native -c eax.cpp
  clang: warning: optimization flag '-fdevirtualize' is not supported
  ...

I believe its equivalent to Microsoft's __declspec(novtable), and I
believe/know Clang supports the MS platform.

Does Clang offer an equivalent flag?

Thanks in advance.
