- Subject: [patch] Remove all current_gdbarch's in mn10300
Hi,
this patch removes the last occurences of current_gdbarch in mn10300 target. Tested by building mn1030 target.
Ok to commit ?
ChangeLog:
* mn10300-tdep.h (AM33_MODE): Add gdbarch as parameter.
* mn10300-tdep.c (set_reg_offsets, mn10300_analyze_prologue): Use
get_frame_arch to get at the current_architecture. Update AM33_MODE
call.
Regards,
Markus
