v850_register_names, v850_processor_type_table): Declare tables
and structures for handling differences in register names for
v850 and v850e.
(struct reg_list): Define new structure for creating tables
of register bit masks in v850e instrutions.
(handle_prepare, handle_pushm): New helpers for v850_scan_prologue.
(v850_scan_prologue): Recognize v850e instructions: callt, prepare,
and pushm.
(v850_target_architecture_hook): New function to set register
names based on current machine.
(_initialize_v850_tdep): Set up target_architecture_hook.
* config/v850/tm-v850.h (v850_register_names): Declare.
(REGISTER_NAME): Define to refer to v850_register_names.
(SR0_REGNUM, CTBP_REGNUM): Define.
(PS_REGNUM): Redefine in terms of SR0_REGNUM.
Added some generic target-independant code for managing call-dummy frames.

* breakpoint.c: DELETE command will not delete CALL_DUMMY breakpoint.
* blockframe.c: Add target-independant support for managing
CALL_DUMMY frames on the host side.
* frame.h: Declarations for generic CALL_DUMMY frame support.
* h8300-tdep.c: Add target function calls using generic frame support.
* config/h8300/tm-h8300.h: config for generic target function calls.
start-sanitize-m32r
* m32r-tdep.c: Add target function calls using generic frame support.
* config/m32r/tm-m32r.h: config for generic target function calls.
end-sanitize-m32r
* sh-tdep.c: Add target function calls using generic frame support.
* config/sh/tm-sh.h: config for generic target function calls.
start-sanitize-v850
* v850-tdep.c: Add target function calls using generic frame support.
* config/v850/tm-v850.h: config for generic target function calls.
end-sanitize-v850
* valops.c: ADD PUSH_RETURN_ADDRESS so that it doesn't have to be
done by PUSH_ARGUMENTS when there's no CALL_DUMMY.
prologues correctly. First, prologue end is now defined by
presence of a branch, jump or call insn. Second, can no longer
fix frame offsets because we may not know the offset until after a
register has been saved.
* (v850_init_extra_frame_info): Fixup frame offsets here because
we have all the info at this time.
* (v850_frame_chain): Use new calling convention for scan_prologue.
errors unique.
* testsuite/gdb.base/nodebug.exp: Whack out all -g options
explicitly.
* v850-tdep.c (v850_init_extra_frame_info v850_frame_chain): Fix
sign bugs with scanning prologues. Get a little smarter about
calculating the length of uninteresting instructions.
LOC_LOCAL_ARG as arguments so that GDB will know about function
args declared this way. Mostly affects dwarf.
* dwarfread.c (decode_die_type): Change default type from int to
void. This allows GDB to recognize void functions.
* (new_symbol): If AT_PROTOTYPED is present, set a flag in the
type structure.
* findvar.c (extract_floating store_floating): Clean up comments
to reflect reality.
* gdbtypes.h: Add TYPE_FLAG_PROTOTYPED so that we can tell if a
function has a prototype. Currently, only dwarf supports this.
* utils.c (floatformat_from_doublest): Fix logic error with
converting from double to float. (It wasn't shifting mant_long if
it had a hidden bit.)
* v850-tdep.c: Add support for function calling. Fix some
problems with debugging code w/o debug symbols.
* config/v850/tm-v850.h: Ditto.
struct frame to make it possible to use frame_saved_args in
EXTRA_FRAME_INFO macro.
* v850-tdep.c config/v850/tm-v850.h: Lotsa new functions and
macros to make frame operations (such as backtrace) work.
