arm.c (add_constant): When taking the address of an item in the pool, get the mode of the item addressed.
* arm.c (add_constant): When taking the address of an item in the
pool, get the mode of the item addressed.
* arm.c (final_prescan_insn case INSN): If an insn doesn't
contain a SET or a PARALLEL, don't consider it for conditional
execution.
Restore ABI compatibility for NetBSD.
* arm/netbsd.h (DEFAULT_PCC_STRUCT_RETURN): Override setting in arm.h
(RETURN_IN_MEMORY): Likewise.
