* coffread.c (coff_symtab_read): In the case of C_THUMBEXT |
 	C_THUMBEXTFUNC | C_EXT, sec will never ever be the index for
 	.rodata, because cs_to_section doesn't deal with .rodata. Fix test
 	accordingly.

* solib.c (symbol_add_stub): Remember the index and the name of
        the section with the lowest address. Use this data (instead of
        data from .text) to pass info into symbol_file_add.

        * elfread.c (record_minimal_symbol_and_info): Use the section
        where the symbol lives to get the index, instead of guessing.

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.

* procfs.c: Cleanup of procfs tracing.  Move defines and
        prototypes to proc-utils.h
        * proc-utils.h: Define tracing macros.  Declare trace functions.
        * proc-api.c: Make procfs tracing a runtime option.
        (prepare_to_trace): New function, abstracted out of several
        places.  Open a trace file if one is required.
        (ioctl_with_trace, write_with_trace, open_with_trace,
        close_with_trace, wait_with_trace, lseek_with_trace):
        Report errno if an error occurs in a system call.

* elfread.c (elf_symtab_read): The calculation of 'offset'
         must be done for each symbol, not just once. The index
         used must be the index of the section where 'sym' resides,
         not .text.

6c1a54b22b 2000-05-05 Michael Snyder <msnyder@seadog.cygnus.com>
* procfs.c (many functions): change int cmd; to long cmd;
        Solaris /proc API calls this parameter a long, and requires it
        for 64-bit hosts (where sizeof(long) != sizeof(int)).  UnixWare
        calls it an int, but on existing UnixWare hosts, int and long
        are the same size.  So long it must be.  If a future UnixWare
        version has problems with this, we'll have to use autoconf.
        * proc-api.c (write_with_trace): use long instead of int.

* solib.c (elf_locate_base, info_sharedlibrary_command):
        Look at the bfd to determine if it is elf32 or elf64, rather
        than using an ifdef.  This makes it runtime teststable and
        multi-arch.

        sect_index_bss to objfile structure.
        * gdb-stabs.h (SECT_OFF_DATA, SECT_OFF_TEXT, SECT_OFF_BSS,
