John Gilmore 2a021f21e9 * stabsread.c (define_symbol): Complain about unrecognized names
that begin with CPLUS_MARKER (often '$'), but don't die.  Fix
suggested by gb@cs.purdue.edu (Gerald Baumgartner).

vtable pointer member name (_vptr$) in $vf abbrevs or unrecognized

John Gilmore 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.

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