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>
