- Reply-to: gdb-patches <gdb-patches at sources dot redhat dot com>
Hi,
since multi-arching is treated obvious, I've just checked in
the first step in multi-arching the v850 target.

2002-05-16 Corinna Vinschen <vinschen@redhat.com>
* v850-tdep.c: Begin multi-arch'ing v850.
(v850_target_architecture_hook): Remove function.
(v850_gdbarch_init): New function. Add code previously in
v850_target_architecture_hook().
(_initialize_v850_tdep): Don't set target_architecture_hook.
Call register_gdbarch_init() instead.
