Anything I need to be aware of if I use -Xdisable-phases=Devirtualization?
Performance penalty?

[Markus Böck]

Slight performance penalty. Basically disables an optimization where the compiler tries to deduce the actual real type of the value to make a normal function call to the overwritten method instead of doing a virtual function call

[Markus Böck]

Basically nothing though probably

[Marc Knaup]

Alright, thank you very much 🙂

It's one indirection less though for every virtual function call. It really depends on the application, the performance impact can also be significant.
