2004-08-25  Jim Blandy  <jimb@redhat.com>

	Merge changes from trunk:

	2004-08-09  Jim Blandy  <jimb@redhat.com>

	* rs6000-tdep.c (set_sim_regno, init_sim_regno_table,
	rs6000_register_sim_regno): Doc fixes.

	2004-08-04  Jim Blandy  <jimb@redhat.com>

	* ppc-linux-nat.c (fetch_register): Replace 'gdb_assert (0)' with
	a call to 'internal_error', with a more helpful error message.
	* rs6000-tdep.c (e500_pseudo_register_read,
	e500_pseudo_register_write, rs6000_store_return_value): Same.

	Change the layout of the PowerPC E500 raw register cache to allow
	the lower 32-bit halves of the GPRS to be their own raw registers,
	not pseudoregisters.
	* ppc-tdep.h (struct gdbarch_tdep): Remove ppc_gprs_pseudo_p flag;
	add ppc_ev0_upper_regnum flag.
	* rs6000-tdep.c: #include "reggroups.h".
	(spe_register_p): Recognize the ev upper half registers as SPE
	registers.
	(init_sim_regno_table): Build gdb->sim mappings for the upper-half
	registers.
	(e500_move_ev_register): New function.
	(e500_pseudo_register_read, e500_pseudo_register_write): The 'ev'
	vector registers are the pseudo-registers now, formed by splicing
	together the gprs and the upper-half registers.
	(e500_register_reggroup_p): New function.
	(P): Macro deleted.
	(P8, A4): New macro.
	(PPC_EV_REGS, PPC_GPRS_PSEUDO_REGS): Macros deleted.
	(PPC_SPE_GP_REGS, PPC_SPE_UPPER_GP_REGS, PPC_EV_PSEUDO_REGS): New
	macros.
	(registers_e500): Rearrange register set so that the raw register
	set contains 32-bit GPRs and upper-half registers, and the SPE
	vector registers become pseudo-registers.
	(rs6000_gdbarch_init): Don't initialize tdep->ppc_gprs_pseudo_p;
	it has been deleted.  Initialize ppc_ev0_upper_regnum.  Many other
	register numbers are now the same for the E500 as they are for
	other PowerPC variants.  Register e500_register_reggroup_p as the
	register group function for the E500.
	* Makefile.in (rs6000-tdep.o): Update dependencies.

	Adapt PPC E500 native support to the new raw regcache layout.
	* ppc-linux-nat.c (struct gdb_evrregset_t): Doc fixes.
	(read_spliced_spe_reg, write_spliced_spe_reg): Deleted.
	(fetch_spe_register, store_spe_register): Handle fetching/storing
	all the SPE registers at once, if regno == -1.  These now take
	over the job of fetch_spe_registers and store_spe_registers.
	(fetch_spe_registers, store_spe_registers): Deleted.
	(fetch_ppc_registers, store_ppc_registers): Fetch/store gprs
	unconditionally; they're always raw.  Fetch/store SPE upper half
	registers, if present, instead of ev registers.
	(fetch_register, store_register): Remove sanity checks: gprs are
	never pseudo-registers now, so we never need to even mention any
	registers that are ever pseudoregisters.

	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.

	2004-08-02  Andrew Cagney  <cagney@gnu.org>

	Replace DEPRECATED_REGISTER_RAW_SIZE with register_size.
	* rs6000-tdep.c (rs6000_push_dummy_call)
	(rs6000_extract_return_value): Use register_size.
	...
	* ppc-linux-nat.c (fetch_altivec_register, fetch_register)
	(supply_vrregset, store_altivec_register, fill_vrregset): Ditto.

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

	* rs6000-tdep.c (rs6000_gdbarch_init): The register set used for
	bfd_mach_ppc has no segment registers.

	Include PowerPC SPR numbers for special-purpose registers.
	* rs6000-tdep.c (struct reg): Add new member, 'spr_num'.
	(R, R4, R8, R16, F, P, R32, R64, R0): Include value for
	new member in initializer.
	(S, S4, SN4, S64): New macros for defining special-purpose
	registers.
	(PPC_UISA_SPRS, PPC_UISA_NOFP_SPRS, PPC_OEA_SPRS, registers_power,
	registers_403, registers_403GC, registers_505, registers_860,
	registers_601, registers_602, registers_603, registers_604,
	registers_750, registers_e500): Use them.

	* rs6000-tdep.c (rs6000_gdbarch_init): Delete variable 'power';
	replace references with expression used to initialize variable.

	2004-07-16  Jim Blandy  <jimb@redhat.com>

	* ppc-tdep.h (ppc_spr_asr): Add missing OEA SPR.
        (ppc_spr_mi_dbcam, ppc_spr_mi_dbram0, ppc_spr_mi_dbram1)
	(ppc_spr_md_cam, ppc_spr_md_ram0, ppc_spr_md_ram1): Add
	missing MPC823 SPRs.
	(ppc_spr_m_twb): Renamed from ppc_spr_md_twb; the old name was
	incorrect.  (This was corrected in GDB's register name tables on
	2004-07-14.)

	* rs6000-tdep.c (registers_602): Correct register name: "esassr"
	should be "esasrr" ("ESA Save and Restore Register").

	2004-07-15  Jim Blandy  <jimb@redhat.com>

	* ppc-tdep.h (struct gdbarch_tdep): New member: ppc_sr0_regnum.
	* rs6000-tdep.c (rs6000_gdbarch_init): Initialize it.

	2004-07-14  Jim Blandy  <jimb@redhat.com>

	* rs6000-tdep.c (COMMON_UISA_NOFP_REGS): Delete; unused.

	* ppc-tdep.h (ppc_num_vrs): New enum constant.

	* ppc-tdep.h (ppc_num_srs): New enum constant.

	manual mentions 'md_twb', but many mention 'm_twb', and at that
	point in the register list.)
