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.

9b280a7f53 RS/6000 portability changes (for hosting cross-debuggers).
* breakpoint.c (fixup_breakpoints):  Re-kludge to IBM6000_TARGET.
* buildsym.c, rs6000-xdep.c, rs6000-tdep.c, tm-rs6000.h,
xcoffexec.c, xcoffread.c:  Rename aixcoff to xcoff everywhere.
* printcmd.c (print_frame_args):  Remove an RS/6000 dependency.
* stabsread.c (define_symbol):  Remove RS/6000 dependencies.
* tm-rs6000.h (ATTACH_DETACH):  Remove: host-dependent.
(PTRACE_ATTACH, PTRACE_DETACH):  Remove: host-dep.
(NO_SINGLE_STEP):  Add, target-dependent.
(loadinfotextindex):  Lowercase, remove "aix_".
* xm-rs6000.h:  Add <sys/ptrace.h> for infptrace.c.
(NO_SINGLE_STEP):  Remove, target-dependent.
* xcoffexec.c (vmap_symtab):  Cleanup #if 0'd code.
* xcoffread.c:  Only build file if RS/6000 native GDB.
(build_function_symbol):  Remove #if 0'd code.
* rs6000-tdep.c:  Cleanup.  Add static fn protos.
Use CORE_ADDR for addresses throughout.  Make void fns void.
(pop_dummy_frame):  Add FIXME about bogosity of design here.
(rs6000_struct_return_address):  Ditto.
(frameless_function_invocation, frame_get_cache_fsr,
frame_initial_stack_address, xcoff_relocate_symtab,
xcoff_init_loadinfo, free_loadinfo, xcoff_add_toc_to_loadinfo,
add_text_to_loadinfo, find_toc_address):  Move from xdep file.
Use CORE_ADDRs.  Change identifiers to lowercase.

* rs6000-xdep.c:  Make whole file conditional on native RS/6000,
supplying dummy routines if non-native.  Add prototype for
static exec_one_dummy_insn.  Move a mess of functions to
rs6000-tdep.c (as above).  Remove #if 0'd code.

* config/rs6000.mh (XDEPFILES):  Move xcoffexec.o to target side.

are initialized to known state to avoid hard to find bugs with gdb
