85f0a8484f * gdbtypes.c (create_array_type): Complete rewrite. Now requires
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.

94daba7f77 * stabsread.c (define_symbol): For the sake of dbx, gcc emits
a single blank as the name of nameless enumerations.  Recognize
	this special case and set nameless flag.

e7177cc2fd (Changes to break incredibly ugly, unmaintainable 750 line
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.

94603999f9 A bunch of changes mostly to improve debugging of C++ programs.
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.

2640f7e138 Removed a large number of changes inserted by Per Bothner
for C++ support.  These will go back in when they've been
examined.
