--- Comment #24 from Ian Lance Taylor <ian at airs dot com> 2011-02-09 14:10:25 UTC --- The first branch of darwin_dbx_register_number looks like it will use the wrong register numbers in debug info. The second branch looks like it will do the wrong thing for -gstabs. I don't think either change is necessary at all given your other patch.
