I think that maintainability of the ARM backend is indeed the major benefit to dropping it. I'm surprised that people are still doing new designs based on ARMv4 (not ARMv4T) systems, but if they are then I suppose that's an argument for leaving the FPA bits hanging around. On the other hand, it's not an argument for not *deprecating* them. We may as well deprecate them now, and then we can remove them later. The actual removal won't happen until at least 4.7, which is probably another couple of years away. Thanks, -- Mark Mitchell CodeSourcery m...@codesourcery.com (650) 331-3385 x713
