/* Target-dependent code for GDB, the GNU debugger.
|
2004-03-15 Andrew Cagney <cagney@redhat.com>
* ppc-tdep.h: Update copyright.
(ppc_linux_supply_gregset, ppc_linux_supply_fpregset): Change
function signatures to match "regsets.h".
* ppc-linux-tdep.c: Include "regset.h".
(ELF_GREGSET_SIZE): Delete.
(right_supply_register): New function.
(ppc_linux_supply_fpregset, ppc_linux_supply_gregset): Rewrite
using right_supply_register.
(ppc32_linux_supply_gregset, ppc64_linux_supply_gregset): New
functions.
(ppc64_linux_gregset, ppc32_linux_gregset): Define.
(ppc_linux_init_abi): Register ppc_linux_regset_from_core_section.
(_initialize_ppc_linux_tdep): Do not register
ppc_linux_regset_core_fns.
(ppc_linux_regset_from_core_section): Replace
fetch_core_registers.
(ppc_linux_regset_core_fns): Delete.
* ppc-linux-nat.c: (right_fill_reg): New function.
(supply_gregset): Update call to ppc_linux_supply_gregset.
(fill_gregset): Clear the register set, use right_fill_reg.
(supply_fpregset): Update call to ppc_linux_supply_fpregset.
(fill_fpregset): Use right_fill_reg, correctly compute FP offsets.

tdep->ppc_fpscr_regnum. The original code replicated the BFD

keep that logic there, and just check the results here.

have floating-point registers, since I can't test this code on
FP-free systems to adapt it.
* ppc-linux-nat.c (ppc_register_u_addr): Don't match against the
fpscr and floating point register numbers if they don't exist.
(fetch_register): Assert that we have floating-point registers
before we reach the code that handles them.
(store_register): Same. And use tdep instead of calling
gdbarch_tdep again.
(fill_fpregset): Don't try to collect FP registers and fpscr if we
don't have them.
(ppc_linux_sigtramp_cache): Don't record the saved locations of
fprs and fpscr if we don't have them.
(ppc_linux_supply_fpregset): Don't supply fp regs and fpscr if we
don't have them.
* ppcnbsd-nat.c: #include "gdb_assert.h".
(getfpregs_supplies): Assert that we have floating-point registers.

floating point register numbers if they don't exist.
(fetch_inferior_registers, store_inferior_registers,
fetch_core_registers): Only fetch / store / supply the
floating-point registers and the fpscr if we have them.
* Makefile.in (ppc-bdm.o, ppc-linux-nat.o, ppcnbsd-nat.o)
(ppcobsd-tdep.o): Update dependencies.

(registers_860, registers_601, registers_602, registers_603)
(registers_604, registers_750, registers_7400, registers_e500): Delete
variables.
(struct variant): Delete nregs, npregs, num_tot_regs, and regs. Add
tdesc.
(tot_num_registers, num_registers, num_pseudo_registers): Delete.
(variants): Delete outdated comment. Use standard target descriptions
instead of "struct reg" arrays.
(init_variants): Delete.
(rs6000_gdbarch_init): Do not guess word size from the BFD
architecture if we have a target description. Select a variant
before creating a new architecture. Use the variant's target
description if the target did not define a register layout.
Validate target-supplied registers. Reject mismatches. Use
fixed register numbers and new constants instead of magic
numbers. Call set_gdbarch_ps_regnum. Call tdesc_use_registers.
(_initialize_rs6000_tdep): Initialize the preparsed target
descriptions.
* target-descriptions.c (tdesc_predefined_types): Add int128 and
uint128.
(tdesc_find_register_early): New function.
(tdesc_numbered_register): Use it.
(tdesc_register_size): New function.
(tdesc_use_registers): Take a target_desc argument. Do not use
gdbarch_target_desc.
* target-descriptions.h (tdesc_use_registers): Update prototype
and comment.
(tdesc_register_size): New prototype.
* Makefile.in (powerpc_32_c, powerpc_403_c, powerpc_403gc_c)

(rs6000-tdep.o): Update.
* arm-tdep.c (arm_gdbarch_init): Update call to tdesc_use_registers.
* m68k-tdep.c (m68k_gdbarch_init): Likewise.
* mips-tdep.c (mips_gdbarch_init): Likewise.
* gdb.texinfo (Predefined Target Types): Add int128
and uint128.
(Standard Target Features): Add PowerPC features.
* gdb.xml/tdesc-regs.exp: Add PowerPC support.
* sim-ppc.h (sim_spr_register_name): New prototype.
* gdb-sim.c (regnum2spr): Rename to...
(sim_spr_register_name): ... this. Make global.
