[LLVMdev] isa and friends as an alternative to dynamic cast?

[Jeff Cohen]

This may be the case with GCC, but VC++ allows exception handling to be 
enabled while RTTI is disabled.  According to VC++ documentation, RTTI 
is needed only to support dynamic_cast, the typeid operator, and the 
type_info class.
