should no longer be used in code specific to the RS6000 and its
derivatives.
* ppc-tdep.h (struct gdbarch_tdep): Add 'ppc_fp0_regnum' member.
* rs6000-tdep.c (rs6000_gdbarch_init): Initialize
tdep->ppc_fp0_regnum.
(ppc_supply_fpregset, ppc_collect_fpregset)
(rs6000_push_dummy_call, rs6000_extract_return_value)
(rs6000_dwarf2_stab_reg_to_regnum, rs6000_store_return_value)
(rs6000_frame_cache): Use tdep->ppc_fp0_regnum instead of
FP0_REGNUM.
* aix-thread.c (supply_fprs, fetch_regs_kernel_thread)
(fill_gprs64, fill_gprs32, fill_fprs, store_regs_kernel_thread):
Same.
* ppc-bdm.c (bdm_ppc_fetch_registers, bdm_ppc_fetch_registers,
bdm_ppc_store_registers): Same.
* ppc-linux-nat.c (ppc_register_u_addr, fetch_register)
(store_register, fill_fpregset): Same.

Same.
