2002-01-20 Andrew Cagney <ac131313@redhat.com>
* remote-sim.c (gdbsim_open): Simplify code testing the macro
TARGET_BYTE_ORDER_SELECTABLE_P. Assume the target is always
byte-order selectable.
* sparc-tdep.c (sparc_target_architecture_hook): Ditto.
* arch-utils.c: Ditto.
(set_endian): Ditto.
(set_endian_from_file): Ditto.
* gdbserver/low-sim.c (create_inferior): Ditto.
* gdbarch.sh: Ditto.
* gdbarch.h: Re-generate.
* config/powerpc/tm-ppc-eabi.h (TARGET_BYTE_ORDER_SELECTABLE_P):
* config/sparc/tm-sparclite.h (TARGET_BYTE_ORDER_SELECTABLE):
* config/sparc/tm-sparclet.h (TARGET_BYTE_ORDER_SELECTABLE):

* config/arm/tm-arm.h (TARGET_BYTE_ORDER_SELECTABLE_P): Delete
macro definition.
