gdb/ChangeLog: 

2004-07-20  Jim Blandy  <jimb@redhat.com>

	Use a fixed register numbering when communicating with the PowerPC
	simulator.
	* ppc-tdep.h (struct gdbarch_tdep): New member: 'sim_regno'.
	* rs6000-tdep.c: #include "sim-regno.h" and "gdb/sim-ppc.h".
	(set_sim_regno, init_sim_regno_table, rs6000_register_sim_regno):
	New functions.
	(rs6000_gdbarch_init): Register rs6000_register_sim_regno.  Call
	init_sim_regno_table.
	* Makefile.in (gdb_sim_ppc_h): New variable.
	(rs6000-tdep.o): Update dependencies.

include/gdb/ChangeLog:
2004-07-20  Jim Blandy  <jimb@redhat.com>

	* sim-ppc.h: New file.

sim/ppc/ChangeLog:
2004-07-20  Jim Blandy  <jimb@redhat.com>

	Use a fixed register numbering when communicating with the PowerPC
	simulator.
	* sim_calls.c: #include "registers.h" and "gdb/sim-ppc.h"; do not
	include GDB's "defs.h".
	(gdb_register_name_table): New variable.
	(gdb_register_name_table_size): New enum constant.
	(gdb_register_name): New function.
	(sim_fetch_register, sim_store_register): Use gdb_register_name,
	instead of calling gdbarch_register_name.
	* Makefile.in (GDB_SIM_PPC_H): New variable.
	(DEFS_H): Delete variable.
	(sim_calls.o): Update dependencies.
