ChangeLog: * target.h (enum strata): New value arch_stratum. * target.c (target_require_runnable): Skip arch_stratum targets. * configure.tgt (powerpc-*-linux* | powerpc64-*-linux*): Add solib-spu.o and spu-multiarch.o to gdb_target_obs. * Makefile.in (ALL_TARGET_OBS): Add solib-spu.o and spu-multiarch.o. (ALLDEPFILES): Add solib-spu.c and spu-multiarch.c. * solib-spu.c: New file. * solib-spu.h: New file. * spu-multiarch.c: New file. * spu-tdep.h (SPUADDR, SPUADDR_SPU, SPUADDR_ADDR): New macros. * spu-tdep.c (struct gdbarch_tdep): New member id. (spu_gdbarch_id): New function. (spu_lslr): New function. (spu_address_to_pointer): New function. (spu_pointer_to_address): Support SPU ID address encoding. Use spu_gdbarch_id and spu_lslr.
