Subject: 	* param-no-tm.h: Make BITS_BIG_ENDIAN defined to 0/1, not defined
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=122ad9abf278d8b86f00d33ff6c1c2e450d4ffc3;p=binutils-gdb.git

	* param-no-tm.h: Make BITS_BIG_ENDIAN defined to 0/1, not defined
	or not defined.  Don't define it based on TARGET_BYTE_ORDER if
	it's already defined (in the tm.h file).
	mips-opcode.h (BIT_FIELDS_*),
	values.c (modify_field, unpack_field_as_long):
	Use #if BITS_BIG_ENDIAN not #ifdef BITS_BIG_ENDIAN.
