Depends on details of the type model. With what we have now, it can't fail. > But that's a more general OO problem.

I think we're all in agreement on that one!! Messy... I've got the arm9 and armv7m sections of the type tree cleaned up and sanity tested with target_to_FOO(). When more is working, I'll post a branch somewhere. Later tasks can be making "arm926 is-a target" work; and restructuring to get a base class for non-M ARMs. - Dave _______________________________________________ Openocd-development mailing list Openocd-development@lists.berlios.de https://lists.berlios.de/mailman/listinfo/openocd-development
