* sparc-tdep.c (NUM_SPARC_FPREGS): Define.
(SPARC_INTREG_SIZE): Define.
(*): Use SPARC_INTREG_SIZE instead of REGISTER_RAW_SIZE (intreg)
where appropriate.
(enum branch_type): New value `done_retry'.
(isbranch): Renamed from isannulled. All callers changed.
Support new sparc64 branch insns.
(single_step): Handle done_retry.
(sparc_extract_struct_value_address): Don't assume 4 byte regs.
(get_saved_register): Likewise.
(sparc_push_dummy_frame): Likewise.
(sparc_frame_find_saved_regs): Likewise.
(sparc_pop_frame): Likewise. Don't refer to FPS_REGNUM, CPS_REGNUM,
or PS_REGNUM if not sparc64. sparc64 has 64 fp regs.
(sparc64_extract_struct_value_address): New function.
(dump_ccreg, sparc_print_register_hook): Likewise.
* sp64-tdep.c: Deleted.
* sparc/tm-sp64.h (GDB_TARGET_IS_SPARC64): Define.
(NUM_REGS): Reduce by 2, cle/tle are in the pstate reg.
(CC_HAS_LONG_LONG): Define.
(REGISTER_NAMES): Delete cle/tle and reorganize.
(PS_REGNUM, FPS_REGNUM, CPS_REGNUM): Delete, they're ifdef'd out of
sparc-tdep.c now.
(REGISTER_BYTES): Update.
(REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW): Delete.
(EXTRACT_RETURN_VALUE): Delete. Use definition in tm-sparc.h.
(NO_SINGLE_STEP): Likewise.
* sparc/tm-sparc.h (EXTRACT_VALUE_RETURN): Don't assume 4 byte regs.
* sparc/sp64.mt: Move simulator support ...
* sparc/sp64sim.mt: ... to here.
