The old way (using #undef in tm.h) was ugly and asking for
trouble, because it makes it possible for some file to use the
wrong definition. Move definition of HOST_CHAR_BIT after definition
of TARGET_CHAR_BIT.
* config/alpha/tm-alpha.h, config/h8300/tm-h8300.h,
config/h8500/tm-h8500.h, config/z8k/tm-z8k.h: Don't undef TARGET_*_BIT
before defining them.
hppa-tdep.c (pa_print_fp_reg), infcmd.c (do_registers_info),
valops.c (value_assign): Use REGISTER_CONVERT_TO_* only if
REGISTER_CONVERTIBLE is defined, otherwise just copy the content.
Pass desired type to REGISTER_CONVERT_TO_*.
* config/m68k/tm-m68k.h, config/i960/tm-i960.h (REGISTER_CONVERT_*):
Pass length of desired type to store/extract_floating.

Use extract_floating and store_floating with length of desired type.
* config/m68k/tm-news.h (STORE,EXTRACT_RETURN_VALUE): Add type
parameter to REGISTER_CONVERT_*.

config/vax/tm-vax.h, config/z8k/tm-z8k.h (REGISTER_CONVERTIBLE,
REGISTER_CONVERT_TO_RAW, REGISTER_CONVERT_TO_VIRTUAL): Remove
versions for which REGISTER_CONVERTIBLE is always false.
* z8k-tdep.c (register_convert_to_virtual, register_convert_to_raw):
Remove, no longer used.
* alpha-tdep.c (alpha_register_convert_to_raw,
alpha_register_convert_to_virtual): New routines to handle
the different raw formats in alpha floating point registers.
* config/alpha/tm-alpha.h (REGISTER_CONVERTIBLE,
REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW): Use them.
about SHIFT_INST_REGS.
* exec.c (exec_file_command): Set text_end based on all code readonly

z8k-tdep.c: Remove all references to ADDR_BITS_SET.
* config/m88k/tm-m88k.h: Define TARGET_WRITE_PC.
* config/m88k/tm-m88k.h: Add definitions for calling functions.
of reading/writing registers that are shorter than REGISTER_TYPE.
* (value_from_register): Install H8500 specific code to return
proper value when register is being used as a pointer.
* h8500-tdep.c: Remove extra defines of NUM_REGS.
(h8500_skip_prologue): Use correct lengths for LINK instructions.
(FRAME_CHAIN): Change name to h8500_frame_chain. Rewrite code to
chain frames properly by combining frame pointer with T reg.
(init_extra_frame_info): Delete. It's now a macro.
(frame_args_address): Don't add PTR_SIZE. Stack args are already
offset by the correct amount off of the frame pointer.
(register_byte): Delete. It's now a macro.
(register_raw_size, register_virtual_size): Delete. Replaced by
common routine h8500_register_size, cuz there's no difference
between the raw & virtual sizes on this machine.
(register_convert_to_raw, register_convert_to_virtual): Delete,
cuz there's no difference between the raw & virtual forms.
Replaced by memcpy in tm file.
(register_virtual_type): Rename to h8500_register_virtual_type.
Get rid of pointer pseudo-regs, use _REGNUM with all reg names.
(_initialize_h8500_tdep): Get rid of crock to ensure that GDB &
emulator have same reg offsets. This is all handled in the
simulator code now.
(h8500_trapped_internalvar): New routine to detect references to
convenience vars acting as pointer pseudo-regs.
(h8500_value_trapped_internalvar): Conjure up value of pointer
pseudo-regs.
(h8500_set_trapped_internalvar): Convert set value in real
register references.
infcmd.c (read_pc, write_pc): Add h8500 specific code to handle
code segment register.
infrun.c (proceed): Simplify. Call write_pc instead of doing it
by hand.
(wait_for_inferior): Add h8500 specific code to add stack segment
when reading SP register.
remote-sim.c (fetch_register): Spacing.
tm-h8500.h: #define GDB_TARGET_IS_H8500 to make it easier to
detect cruft. Redo all register manipulation stuff. Get rid of
pointer pseudo-regs. (INIT_EXTRA_FRAME_INFO): Adds stack segment
to frame pointer. (IS_TRAPPED_INTERNALVAL,
VALUE_OF_TRAPPED_INTERNALVAR, SET_TRAPPED_INTERNALVAR): Use these
to create internal vars for pointer pseudo-regs.
config files moved to an appropriate config/<cpu> subdirectory.
* nm-*, xm-*, tm-*: All native, host, and target files, which
get linked to nm.h, xm.h, and tm.h respectively by configure,
moved to appropriate config/<cpu> subdirectory.
