Make Sparc a Multi-Arch target. Discard PARAMS macro (require ANSI).
* sparc-tdep.c: include arch-utils.h.
(SPARC_HAS_FPU, FP_REGISTER_BYTES, FP_MAX_REG NUM, SPARC_INTREG_SIZE,
DUMMY_REG_SAVE_OFFSET): provide multi-arch-compatible definitions.
(GDB_TARGET_IS_SPARC64): make into a runtime test.
(struct frame_extra_info): Define, use instead of the macro.
(Many places): Use alloca instead of statically allocated buffers
that depend on a multi-arch variable such as MAX_REGISTER_RAW_SIZE.
(sparc_extract_struct_value_address): Accept a pointer arg instead
of an array sized by REGISTER_BYTES.
(examine_prologue): Accept a pointer to an array of CORE_ADDR,
instead of the defunct struct frame_saved_regs. Recognize new
Sparc64 store instructions as part of the prologue. Ignore the
destination of a frame store when parsing the prologue (so long
as it's on the stack).
(sparc_push_dummy_frame): Fix incorrect buffer offset for PSTATE.
(sparc_frame_find_saved_regs): Accept a ptr to an array of CORE_ADDR
instead of the defunct struct frame_saved_regs.
(supply_gregset): Discard unnecessary 'zerobuf': just send NULL to
supply_register. Provide 4-byte offset to compensate for diff
between size of the prgreg_t elements on a 64-bit host and size
of the registers for a 32-bit target. Fill all inaccessible regs
with zero so they won't keep being requested again and again.
(fill_gregset): Handle 32/64 size difference between registers
and prgreg_t. Handle as many new 64-bit regs as possible.
(supply_fpregset, fill_fpregset): Attempt to handle 64-bit world.
(sparc_push_arguments): Rename to sparc32_push_arguments.
Copy arguments into registers as well as onto stack, so that the
CALL_DUMMY (code pushed onto the target stack) is not required.
(sparc_extract_return_value): Rename to sparc32_extract_return_value.
(sparc_store_return_value): Use memset instead of bzero.
Use write_register_gen instead of write_register_bytes.
(sparclet_store_return_value): New function.
(_initialize_sparc_tdep): Call register_gdbarch_init to activate
the gdbarch multi-architecture system.
(sp64_push_arguments): Rename to sparc64_push_arguments.
Extend to store arguments in general registers as well as on stack.
(sparc64_extract_return_value): Rename to sp64_extract_return_value.
Use as a private function, to be called by the new external function
sparc64_extract_return_value.
(sparclet_extract_return_value): New function.
(sparc32_stack_align, sparc64_stack_align, sparc32_register_name,
sparc64_register_name, sparc_print_extra_frame_info,
sparclite_register_name, sparclet_register_name,
sparc_push_return_address, sparc64_use_struct_convention,
sparc32_store_struct_return, sparc64_store_struct_return,
sparc32_register_virtual_type, sparc64_register_virtual_type,
sparc32_register_size, sparc64_register_size,
sparc32_register_byte, sparc64_register_byte,
sparc_gdbarch_skip_prologue, sparc_convert_to_virtual,
sparc_convert_to_raw, sparc_frame_init_saved_regs,
sparc_frame_address, sparc_gdbarch_fix_call_dummy,
sparc_coerce_float_to_double, sparc_call_dummy_address,
sparc_y_regnum, sparc_reg_struct_has_addr, sparc_intreg_size,
sparc_return_value_on_stack): New functions supporting multi-arch.
(sparc_gdbarch_init): New function; initialize multi-arch.
(struct gdbarch_tdep): Define, use for private multi-arch data.
* config/sparc/tm-sparc.h: Move definitions around, enclose with
#ifdef GDB_MULTI_ARCH tests, provide some multi-arch alternate
definitions. Add enums for register names, to help debugging gdb.
This header file must work for non-multi-arch and for multi-arch.
* config/sparc/tm-sp64.h: Add GDB_MULTI_ARCH configuration. Also add
AT_ENTRY_POINT definitions for CALL_DUMMY, for non-multi-arch case.
Define GDB_MULTI_ARCH.
* config/sparc/tm-sparclet.h: Add GDB_MULTI_ARCH configuration.
Do not define GDB_MULTI_ARCH (bfd does not correctly identify target).
* config/sparc/tm-sparclite.h: Ditto.
* config/sparc/tm-sun4sol2.h: Define GDB_MULTI_ARCH.
* sparclet-rom.c (sparclet_regnames): Initialize explicitly, to
avoid using deprecated REGISTER_NAMES macro.
* Makefile.in: Let sparc-tdep.c depend on arch-utils.h.
