	                 values.c 

Log message:
	Clean up the D10V port so that GDB and the target program no
	longer disagree on how big pointers are.
	* findvar.c (value_from_register): Remove special case code for D10V.
	* printcmd.c (print_frame_args): Same.
	* valops.c (value_at, value_fetch_lazy): Same.
	* values.c (unpack_long): Same.
	* gdbarch.sh: Changes to effect the following:
	* gdbarch.h (GDB_TARGET_IS_D10V, D10V_MAKE_DADDR,
	gdbarch_d10v_make_daddr_ftype, gdbarch_d10v_make_daddr,
	set_gdbarch_d10v_make_daddr, D10V_MAKE_IADDR,
	gdbarch_d10v_make_iaddr_ftype, gdbarch_d10v_make_iaddr,
	set_gdbarch_d10v_make_iaddr, D10V_DADDR_P,
	gdbarch_d10v_daddr_p_ftype, gdbarch_d10v_daddr_p,
	set_gdbarch_d10v_daddr_p, D10V_IADDR_P,
	gdbarch_d10v_iaddr_p_ftype, gdbarch_d10v_iaddr_p,
	set_gdbarch_d10v_iaddr_p, D10V_CONVERT_DADDR_TO_RAW,
	gdbarch_d10v_convert_daddr_to_raw_ftype,
	gdbarch_d10v_convert_daddr_to_raw,
	set_gdbarch_d10v_convert_daddr_to_raw, D10V_CONVERT_IADDR_TO_RAW,
	gdbarch_d10v_convert_iaddr_to_raw_ftype,
	gdbarch_d10v_convert_iaddr_to_raw,
	set_gdbarch_d10v_convert_iaddr_to_raw): Delete declarations.
	* gdbarch.c: Delete the corresponding definitions.
	(struct gdbarch): Delete members d10v_make_daddr,
	d10v_make_iaddr, d10v_daddr_p, d10v_iaddr_p,
	d10v_convert_daddr_to_raw, and d10v_convert_iaddr_to_raw.
	(startup_gdbarch): Remove initializers for the above.
	(verify_gdbarch, gdbarch_dump): Don't verify or dump them any
	more.
	* d10v-tdep.c (d10v_register_virtual_type): Rather that
	claiming the stack pointer and PC are 32 bits long (which they
	aren't), say that the stack pointer is an int16_t, and the
	program counter is a function pointer.  This allows the rest
	of GDB to make the appropriate conversions between the code
	pointer format and real addresses.
	(d10v_register_convertible, d10v_register_convert_to_virtual,
	d10v_register_convert_to_raw): Delete function; no registers
	are convertible now, so we use
	generic_register_convertible_not instead.
	(d10v_address_to_pointer, d10v_pointer_to_address): New gdbarch
	methods.
	(d10v_push_arguments, d10v_extract_return_value): Remove special
	cases for code and data pointers.
	(d10v_gdbarch_init): Set gdbarch_ptr_bit to 16, so that GDB and
	the target agree on how large pointers are.  Say that addresses
	are 32 bits long.  Register the address_to_pointer and
	pointer_to_address conversion functions.  Since no registers are
	convertible now, register generic_register_convertible_not as the
	gdbarch_register_convertible method instead of
	d10v_register_convertible.  Remove registrations for
	d10v_register_convert_to_virtual,
	d10v_register_convert_to_raw, gdbarch_d10v_make_daddr,
	gdbarch_d10v_make_iaddr, gdbarch_d10v_daddr_p,
	gdbarch_d10v_iaddr_p, gdbarch_d10v_convert_daddr_to_raw, and
	gdbarch_d10v_convert_iaddr_to_raw.
