--- Comment #1 from joseph at codesourcery dot com <joseph at codesourcery dot com> 2011-06-15 22:52:07 UTC --- It appears the v850 targets duplicate a lot of standard settings tm_p_file=v850/v850-protos.h tmake_file=v850/t-v850 md_file=v850/v850.md extra_modes=v850/v850-modes.def out_file=v850/v850.c extra_options="v850/v850.opt" all of which could be avoided by setting cpu_type (which would also fix this issue). In general targets setting out_file directly like that are suspect and indicate a missing case in the code setting cpu_type.
