[rfc] [2/6] Remove macro TARGET_BYTE_ORDER


Hello,

this patch removes TARGET_BYTE_ORDER macro from gdbarch.sh.



ChangeLog:

	* gdbarch.sh (TARGET_BYTE_ORDER): Replace by gdbarch_byte_order.
	* ax-gdb.c (gen_bitfield_ref): Likewise.
	* mi/mi-main.c (get_register): Likewise.
	* findvar.c (default_value_from_register, extract_signed_integer)
	(extract_unsigned_integer, extract_long_unsigned_integer)
	(store_signed_integer, store_unsigned_integer): Likewise.
	* regcache.c (regcache_dump): Likewise.
	* value.c (lookup_internalvar, value_of_internalvar)
	(set_internalvar): Likewise.
	* defs.h: Likewise.
	* valprint.c (print_binary_chars, print_octal_chars)
	(print_decimal_chars, print_hex_chars, print_char_chars): Likewise.
	* infcmd.c (default_print_registers_info): Likewise.
	* arch-utils.c (selected_byte_order, show_endian): Likewise.
	* stabsread.c (define_symbol): Likewise.
	* doublest.c (floatformat_from_length, floatformat_from_type)
	(extract_typed_floating, store_typed_floating): Likewise.
	* gdbarch.c, gdbarch.h: Regenerate.


Is this ok to commit?


Regards,
Markus
