characters, just assume a reasonable default, complain, and keep
going.

One result of all this is that '9' (VISIBILITY_IGNORE) can be used
in a stab as well as being something which GDB uses internally.

and macros to handle the bits.
* stabsread.c (read_one_struct_field): add VISIBILITY_IGNORE, and

extract_unsigned_integer instead of SWAP_TARGET_AND_HOST.
Change sizeof (float) to 4 and sizeof (double) to 8 (those are always
the relevant sizes for this code, which is in #ifdef IEEE_FLOAT).
* values.c (unpack_long, unpack_double, value_from_double),
valarith.c (value_binop), stabsread.c (define_symbol):
Use extract_floating and store_floating instead of

Use the name from the BCOMM instead of the ECOMM.
Allocate things on the symbol_obstack.

and C_ECOML. On unrecognized storage classes, go ahead and call
define_symbol (after the complaint).
* dbxread.c (process_one_symbol): Don't relocate 'S' symbols by
the text offset.

Now that we have the bp_call_dummy breakpoint the call dummy code
is no longer needed. PUSH_DUMMY_FRAME, PUSH_ARGUMENTS and
FIX_CALL_DUMMY can be used to set up everything for the dummy.
The breakpoint for the dummy is set at the entry point and thats it.
* blockframe.c (inside_entry_file, inside_entry_func): Do not stop
backtraces if pc is in the call dummy at the entry point.
* infcmd.c (run_stack_dummy): Handle AT_ENTRY_POINT case. Use
the expected breakpoint pc when setting up the frame for
set_momentary_breakpoint.

of create_range_type.
* printcmd.c (ptype_command, ptype_eval, whatis_command,
whatis_exp, maintenance_print_type): Move prototypes and functions

nbytes variable. Change dummy type to 2 bytes to match int.
Handle FT_VOID types gratuituously added to chill DWARF by

* Makefile.in (HFILES): Add complaints.h.
* Makefile.in (OBS): Add complaints.o.
* symfile.c (complaint_root, stop_whining, complaint_series,

Moved to complaints.c.
* symfile.h (struct complaint, complaint_root decl, complain
prototype, clear_complaints prototype): Moved to complaints.h.
* buildsym.c, coffread.c, dbxread.c, dwarfread.c, elfread.c,
gdbtypes.c, mipsread.c, stbsread.c, symfile.c: Include
complaints.h. Remove casts from arguments to complain(),
which is now a varargs function, and remove unnecessary
placeholder zero args.
* defs.h (begin_line): Add prototype.
* defs.h (vprintf_filtered): Add prototype.
* dwarfread.c (varargs.h): Remove, no longer needed.
* dwarfread.c (dwarfwarn): Remove prototype and function.
* dwarfread.c (complaints): Define a bunch of complaints.
* dwarfread.c (SQUAWK): Remove macro defs, convert all
usages to standard complain() calls.
* utils.c (begin_line): New function that ensures that
whatever gets filter-printed next starts on its own line.
* utils.c (vprintf_filtered): New func, like vfprintf_filtered,
but to stdout (calls vfprintf_filtered internally).
a optional type to decorate as an array type, the type of the
index, and the bounds of the array. Records this additional info
in the array type for use with languages with nonzero array
bounds.
* gdbtypes.h (enum type_code): Update comment for TYPE_CODE_ARRAY
to note that arrays may have bounds.
* gdbtypes.h (create_array_type): Update prototype.
* c-exp.y (ptype production): Adjust for new create_array_type
calling conventions.
* coffread.c (decode_type): Call create_array_type rather than
handcrafting array types.
* convex-tdep.c (value_type): Remove, now use create_array_type.
* convex-tdep.c (value_of_trapped_internalvar): Convert calls to
vector_type into calls to create_array_type.
* dwarfread.c (decode_subscr_data): Name changed to
decode_subscript_data_item throughout.
* dwarfread.c (decode_subscript_data_item): Rewrite to use
create_array_type. Now records index type and range as well.
* dwarfread.c (dwarf_read_array_type): Rewrite as part of
change to use create_array_type.
* dwarfread.c (read_subroutine_type): Test existing user defined
types before decorating them, to ensure they are blank, and
complain about it if they are not.
* dwarfread.c (decode_fund_type): For unrecognized types, always
return some valid type (type integer). If the unrecognized type
cannot be an implementation defined type, complain as well.
* m88k-tdep.c (pushed_size): Update comment for TYPE_CODE_ARRAY.
* m88k-tdep.c (store_param): Update comment for TYPE_CODE_ARRAY.
* mipsread.c (upgrade_type): Add FIXME comment that code to
handcraft arrays should be replaced with call to create_array_type.
* stabsread.c (read_array_type): Replace code to handcraft
array types with call to create_array_type.
* valprint.c (type_print_varspec_prefix): Minor formatting
change, join lines that don't need to be split.
read_struct_type function up into managable pieces.)
* stabsread.c (struct field_info): Local struct definition.
* stabsread.c (read_member_functions, read_struct_fields,
read_baseclasses, read_tilde_fields, attach_fn_fields_to_type,
attach_fields_to_type, read_cpp_abbrev): Prototypes and new
functions from fragmented read_struct_type.
* stabsread.c (stabs_general_complaint): Catchall complaint.
* stabsread.c (STABS_CONTINUE): Macro'ize cretinous stabs
symbol name continuation code. Use macro throughout.
* stabsread.c (various places): Replace add-one-to-pointer
with pointer increment.
* stabsread.c (read_type): Retain function local copy of type
descriptor. Rearrange code calling read_struct_type() to match
new conventions.
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.
types.
* stabsread.c (read_array_type, read_range_type, define_symbol):
Call alloc_type to alloc new types.
* stabsread.c (define_symbol): Move dbl_valu symbol field data
from type_obstack to symbol_obstack.
* stabsread.c (define_symbol): Move typedef_sym from type_obstack
to symbol_obstack.
* gdbtypes.h (TYPE_ALLOC): New macro to allocate space for data
associated with a type, using the same mechanism as was used to
allocate space for the type structure itself.
* coffread.c (patch_type, coff_read_struct_type,
coff_read_enum_type): Use TYPE_ALLOC.
* dwarfread.c (struct_type): Use TYPE_ALLOC.
* gdbtypes.c (create_array_type, check_stub_method,
allocate_cplus_struct_type): Use TYPE_ALLOC.
* mipsread.c (parse_symbol, parse_type): Use TYPE_ALLOC.
* stabsread.c (read_struct_type, read_array_type, read_enum_type,
read_range_type): Use TYPE_ALLOC.
