* findvar.c (value_from_register): Remove special case code for D10V.
* printcmd.c (print_frame_args): Same.
* valops.c (value_at, value_fetch_lazy): Same.
* values.c (unpack_long): Same.
* gdbarch.sh: Changes to effect the following:
* gdbarch.h (GDB_TARGET_IS_D10V, D10V_MAKE_DADDR,
gdbarch_d10v_make_daddr_ftype, gdbarch_d10v_make_daddr,
set_gdbarch_d10v_make_daddr, D10V_MAKE_IADDR,
gdbarch_d10v_make_iaddr_ftype, gdbarch_d10v_make_iaddr,
set_gdbarch_d10v_make_iaddr, D10V_DADDR_P,

set_gdbarch_d10v_daddr_p, D10V_IADDR_P,
gdbarch_d10v_iaddr_p_ftype, gdbarch_d10v_iaddr_p,
set_gdbarch_d10v_iaddr_p, D10V_CONVERT_DADDR_TO_RAW,
gdbarch_d10v_convert_daddr_to_raw_ftype,
gdbarch_d10v_convert_daddr_to_raw,
set_gdbarch_d10v_convert_daddr_to_raw, D10V_CONVERT_IADDR_TO_RAW,
gdbarch_d10v_convert_iaddr_to_raw_ftype,
gdbarch_d10v_convert_iaddr_to_raw,
set_gdbarch_d10v_convert_iaddr_to_raw): Delete declarations.
* gdbarch.c: Delete the corresponding definitions.
(struct gdbarch): Delete members d10v_make_daddr,
d10v_make_iaddr, d10v_daddr_p, d10v_iaddr_p,
d10v_convert_daddr_to_raw, and d10v_convert_iaddr_to_raw.
(startup_gdbarch): Remove initializers for the above.
(verify_gdbarch, gdbarch_dump): Don't verify or dump them any
more.
* d10v-tdep.c (d10v_register_virtual_type): Rather that
claiming the stack pointer and PC are 32 bits long (which they
aren't), say that the stack pointer is an int16_t, and the
program counter is a function pointer. This allows the rest
of GDB to make the appropriate conversions between the code
pointer format and real addresses.
(d10v_register_convertible, d10v_register_convert_to_virtual,
d10v_register_convert_to_raw): Delete function; no registers
are convertible now, so we use
generic_register_convertible_not instead.

methods.
(d10v_push_arguments, d10v_extract_return_value): Remove special
cases for code and data pointers.
(d10v_gdbarch_init): Set gdbarch_ptr_bit to 16, so that GDB and
the target agree on how large pointers are. Say that addresses
are 32 bits long. Register the address_to_pointer and
pointer_to_address conversion functions. Since no registers are
convertible now, register generic_register_convertible_not as the
gdbarch_register_convertible method instead of
d10v_register_convertible. Remove registrations for
d10v_register_convert_to_virtual,
d10v_register_convert_to_raw, gdbarch_d10v_make_daddr,
gdbarch_d10v_make_iaddr, gdbarch_d10v_daddr_p,
gdbarch_d10v_iaddr_p, gdbarch_d10v_convert_daddr_to_raw, and
gdbarch_d10v_convert_iaddr_to_raw.

predicate.
* gdbarch.h, gdbarch.c: Regenerate.
* values.c (value_being_returned): Change the reference to
EXTRACT_STRUCT_VALUE_ADDRESS_P to a function call.
Changes by Jim Ingham:

mean it is the one, some times a typedef class can have the same
memeber method and args. This probably will not happen with new

Change all references to stdout/stderr to gdb_stdout/gdb_stderr.
Replace all calls to stdio output functions with calls to
corresponding _unfiltered functions (`fprintf_unfiltered')
Replaced calls to fopen for output to gdb_fopen.
Added sufficient goo to utils.c and defs.h to make the above work.
The net effect is that stdio output functions are only directly used
in utils.c. Elsewhere, the _unfiltered and _filtered functions and
GDB_FILE type are used.
In the near future, GDB_FILE will stop being equivalant to FILE.
The semantics of some commands has changed in a very subtle way:
called in the right context, they may cause new occurences of
prompt_for_continue() behavior. The testsuite doesn't notice anything
like this, though.
Please respect this change by not reintroducing stdio output
dependencies in the main body of gdb code. All output from commands
should go to a GDB_FILE.
Target-specific code can still use stdio directly to communicate with
targets.

**** start-sanitize-chill ****
* Makefile.in (SFILES_MAINDIR): Add ch-typeprint.c, ch-valprint.c.
* Makefile.in (OBS): Add ch-typeprint.o, ch-valprint.o.
* ch-typeprint.c: New file for language dependent type printing.
* ch-valprint.c: New file for language dependent value printing.
* ch-exp.y (parse_number): Remove prototype and stub function.
* ch-exp.y (decode_integer_literal): Removed unused digits and
temp variables.
* ch-exp.y (convert_float): Completely ifdef out for now.
* ch-exp.y (tokentab2, tokentab3, tokentab4, tokentab5),
ch-lang.c (chill_op_print_tab):
Change from ANSI-obsolescent "const static" to ANSI-conformant
"static const".
* ch-exp.y (yylex): Add unhandled storage class enumeration
literals to switch statement for completeness.
* ch-lang.c (chill_create_fundamental_types): Remove unused
nbytes variable. Change dummy type to 2 bytes to match int.
Handle FT_VOID types gratuituously added to chill DWARF by

rather than '$'. This particular piece of braindamage is
spreading like ooze. It's now infected libiberty, deja-gnu,
gdb, and gcc.
* values.c (baseclass_addr): Use CPLUS_MARKER rather than
hardwired '$' character.
Specifically, the calling of inferiors methods is improved.
* value.h: New macros METHOD_PTR_IS_VIRTUAL,
METHOD_PTR_FROM_VOFFSET, METHOD_PTR_TO_VOFFSET to partially
hide the implementation details of pointer-to-method objects.
How to tell if the pointer points to a virtual method is
still very dependent on the particular compiler, but this
should make it easier to find the places to change.
* eval.c (evaluate_subexp [case OP_FUNCALL]), valprint.c
(val_print [case TYPE_CODE_PTR]): Use the new METHOD_PTR_*
macros, instead of a hard-wired-in code that incorrectly
assumed a no-longerused representation of pointer-to-method
values. And otherwise fix the relevant bit-rotted code.
* valprint.c (type_print_base [case TYPE_CODE_STRUCT]):
If there are both fields and methods, put a space between.
* stabsread.c (read_struct_type): Fix bug in handling of
GNU C++ anonymous type (indicated by CPLUS_MARKER followed
by '_'). (It used to prematurely exit the loop reading in
the fields, so it would think it should start reading
methods while still in the fields. This could crash gdb
given a gcc that can emit nested type information.)
* valops.c (search_struct_method): Pass 'this' value by
reference instead of by value. This provides a more
consistent interface through a recursive search where the
"bottom" functions may need to adjust offsets (due to multiple
inheritance).
* valops.c, value.h, values.c: Pass extra parameters to
value_fn_field and value_virtual_fn_field so we can
correctly adjust offset for multiple inheritance.
* eval.c (evaluate_subexp [case OP_FUNCALL]): Simplify
virtual function calls by using value_virtual_fn_field().
* values.c: New function baseclass_offset, derived from
baseclass_addr (which perhaps can be made obsolete?).
It returns an offset rather than an address. This is a
cleaner interface since it doesn't mess around allocating
new values.
* valops.c (search_struct_method): Use baseclass_offset
rather than baseclass_addr.
to create new blank types, instead of handcrafting them.
* defs.h (printfi_filtered): Add prototype.
* utils.c (printfi_filtered): New function.
* gdbtypes.c (recursive_dump_type): Use printfi_filtered to
to simplify the code. Other cleanups.
* gdbtypes.c (check_stub_method): Demangle using DMGL_ANSI.
* gdbtypes.h (struct cplus_struct_type): Add comments describing
use of various fields.
* gdbtypes.c (print_bit_vector, print_cplus_stuff): New functions.
* c-exp.y (%token): Add CLASS as a token for C++, add grammar
production that currently treats it exactly the same as STRUCT.
* c-exp.y (yylex): Recognize "class" as token CLASS.
* symtab.c (gdb_mangle_name): Rewrite to match current g++ stabs.
* symtab.c (decode_line_1): Fix to pass quoted args on down to
general symbol handling code. Call cplus_mangle_opname with
DMGL_ANSI.
* symtab.c (decode_line_2): Print demangled function names in
breakpoint menus, instead of just file and line number.
* symtab.c (name_match): Call cplus_demangle with DMGL_ANSI.
* valprint.c (type_print_base): Print "class" for C++ classes,
rather than "struct". Print section labels for public, protected
and private members of C++ classes.
* values.c: Include demangle.h.
* values.c (value_headof): Call cplus_demangle with DMGL_ANSI.
symtab.h, tm-i386v4.h, valprint.c, values.c: Lint.

putenv.c, solib.c, sparc-xdep.c, symtab.c, tm-i386v.h, tm-sparc.h,
utils.c, valarith.c, valops.c, valprint.c, values.c:
Replace bcopy() use with memcpy(), which is more standard and can
take advantage of gcc's builtin functions for increased performance.
* breakpoint.c, buildsym.c, coffread.c, dbxread.c, i386-tdep.c,
ieee-float.c, infcmd.c, sparc-tdep.c, stack.c, symtab.c, symtab.h,
target.c, values.c:
Replace bzero() use with memset(), which is more standard and can
take advantage of gcc's builtin functions for increased performance.
* i386-tdep.c, main.c, valprint.c:
Replace bcmp() use with memcmp(), which is more standard and can
take advantage of gcc's builtin functions for increased performance.
