* gdbarch.sh (IEEE_FLOAT): New entry.
* gdbarch.c, gdbarch.h: Regenerated.
* valprint.c (IEEE_FLOAT): Provide a default #definition for this.
(print_floating): Use IEEE_FLOAT as if it were an expression; use
the code specific to IEEE-format numbers whenever the value of
IEEE_FLOAT is non-zero.

IEEE_FLOAT, make sure they give it the value (1).
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.

parameter to REGISTER_CONVERT_*.

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.
* Move SWAP_TARGET_AND_HOST from defs.h to findvar.c because it is
now used only by extract_floating and store_floating.
* valprint.c (print_floating): Use unsigned arithmetic. Use
extract_unsigned_integer instead of SWAP_TARGET_AND_HOST.
Change sizeof (float) to 4 and sizeof (double) to 8 (those are always
the relevant sizes for this code, which is in #ifdef IEEE_FLOAT).
* values.c (unpack_long, unpack_double, value_from_double),
valarith.c (value_binop), stabsread.c (define_symbol):
Use extract_floating and store_floating instead of
SWAP_TARGET_AND_HOST.
* config/m68k/tm-m68k.h, config/i960/tm-i960.h (REGISTER_CONVERT_*):
Use extract_floating and store_floating.
* config/m88k/tm-m88k.h: Add comments (it should be doing the same).
* i386-tdep.c (i386_extract_return_value),
* remote-nindy.c (nindy_store_registers): Use store_floating.
about SHIFT_INST_REGS.
* exec.c (exec_file_command): Set text_end based on all code readonly
sections, not just ".text".

* config/m88k/tm-m88k.h: Define TARGET_WRITE_PC.
* config/m88k/tm-m88k.h: Add definitions for calling functions.
ieee-float.h. expanded to cope with m88110 extended registers.
(R0_REGNUM, XFP_REGNUM, X0_REGNUM): new macros.
(SHIFT_INST_REGS): becomes a real macro.
(FP_REGNUM): define in terms of SP_REGNUM
rather than by absolute number. Also clearly comment that this
is a convenient lie in order to decrease future confusion.
(ACTUAL_FP_REGNUM): new macro for FP.
(FRAME_CHAIN_VALID): removed. Standard default works fine.
* m88k-tdep.c (frame_chain_valid): redundant, so removed.
(NEXT_PROLOGUE_INSN): removed unused fourth arg, fixed all
callers.
(read_next_frame_reg): declare static.
(examine_prologue): removed unused variabel insn2, rename insn1
to insn, rewrote comment about finding fp, sp, etc. set frame_fp
based on ACTUAL_FP_REGNUM rather than FP_REGNUM which is
actually a scammed alias for SP_REGNUM on m88k.
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.
