Subject: 	* callback.c (default_callback): Initialize target_endian.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=f4f8cce440a38bf606aab597fd9ccb324f0fee87;p=binutils-gdb.git

	* callback.c (default_callback): Initialize target_endian.
	(cb_store_target_endian): Renamed from store, new first parameter
	host_callback *cb, drop last parameter big_p.  Take endianness
	from cb.
	(cb_host_to_target_stat): Change to use cb_store_target_endian.
	Remove variable big_p.
	* nrun.c (main): Initialize default_callback.target_endian.
