I don't believe so. As I understand it, you might not have a process yet when you call `LanguageRuntime::CreateExceptionBreakpoint` from `Target`, so you won't have an instance of LanguageRuntime. You could create an instance of a LanguageRuntime object with a nullptr process just to invoke it as an instance method, but that seems like the wrong choice to me. All this combined has led me to believe that `AddExceptionPrecondition` needs to get a callback to a static function from PluginManager. > Also, I think it's totally reasonable to hoist `BreakpointPrecondition` out > of `Breakpoint`.

Yeah, I was kinda iffy on this, but if you (and possibly others) think this is reasonable, I might go with this option. The only thing that would change is the callback would return a `BreakpointPreconditionSP` instead of `void`, and `AddExceptionPrecondition` would be the one to modify the breakpoint. I don't think the core idea would change much but the implementation might be slightly nicer. Let me know if you prefer that.
