IMO they should make -d2SSAOptimizerUndefinedIntOverflow- a permanent option (i.e. not a hidden flag). I also think they should automatically enable it (that is, disable the optimizations) if the /sdl option is passed to the compiler (I'll accept this instead of making it a permanent flag). The logic being that you really don't care about the performance if you're using /sdl to begin with and would rather it just generate safer secure code.

Edit: Also keep in mind that to disable these optimizations the complete flag is "-d2SSAOptimizerUndefinedIntOverflow-" minus quotations. That is it includes the dash/minus at the end to disable it.

Why would you have it automatically enabled?

If you write MSVC only code you can add it to your compiler options for the projects that use this new compiler.

If you write cross platform code this is (potentially) one less thing that is different between compilers.
