* defs.h: If TARGET_BYTE_ORDER_SELECTABLE is defined by tm.h,
define TARGET_BYTE_ORDER as target_byte_order, and declare
target_byte_order as an extern int, and define BITS_BIG_ENDIAN as
a test of TARGET_BYTE_ORDER.
* top.c: Several additions if TARGET_BYTE_ORDER_SELECTABLE is
defined:
(endianlist, target_byte_order): New variables.
(set_endian, set_endian_big, set_endian_little): New functions.
(show_endian): New function.
(init_cmd_lists): Initialize endianlist.
(init_main): Add commands ``set endian big'', ``set endian
little'', and ``show endian''.
* a29k-pinsn.c: Rewrite uses of TARGET_BYTE_ORDER and
BITS_BIG_ENDIAN to switch at run time rather than at compile time.
* coffread.c, dwarfread.c, findvar.c, mips-tdep.c: Likewise.
* remote-os9k.c, stabsread.c, valarith.c, valprint.c: Likewise.
* values.c: Likewise.
* mips-tdep.c: Rewrite uses of GDB_TARGET_IS_MIPS64 to switch at
run time rather than at compile time.
