these routines much smarter about updating registers from the
target, only doing so when absolutely necessary. This really
speeds up register modification on some remote targets.
* monitor.c: More cleanups. Get rid of monitor_load_ascii_srec.
BFD makes this unnecessary. Lots of debugging speedups.
* (expect): NULL terminate return string.
* (monitor_open monitor_supply_register parse_register_dump
monitor_wait monitor_fetch_register): Switch to using GNU regexp
library to parse multi-register displays.
* (monitor_read_memory): Read multiple bytes (up to 16) at once.
* (monitor_create_inferior): Call clear_proceed_status to make run
command notice first breakpoint.
* (monitor_load): Clean up. Reset inferior_pid, set pc to start
address and reset symbol table stuff to make loads put things into
a fresh state.
* (monitor_load_srec): Lower sleep time to 1 second.
* monitor.h (struct monitor_ops): Add register_pattern and
supply_register to monitor_ops.
* rom68k-rom.c: Add new support for handling register dumps.
* config/m68k/tm-m68k.h: Define D0_REGNUM and A0_REGNUM for register
dump handling.
* m68k-tdep.c (m68k_saved_pc_after_call): Get rid of
GDB_TARGET_IS_SUN3. Use more general SYSCALL_TRAP macro.
* config/m68k/m68klynx.mh (NATDEPFILES): Remove exec.o (it's
already in TDEPFILES).
* config/m68k/tm-m68k.h (SAVED_PC_AFTER_CALL): Use
m68k_saved_pc_after_call.
* Remove all Sun3 specific stuff.
* (FIX_CALL_DUMMY): Cast arg to bfd_putb32 to unsigned char *.
* config/m68k/tm-m68klynx.h: Define SYSCALL_TRAP as trap #10.
Disable REMOTE_BREAKPOINT mechanism.
* config/m68k/tm-sun3.h: Get rid of GDB_TARGET_IS_SUN3.
* Protect from multiple includion.
* Move Sun3 specific stuff from tm-m68k.h to here.
* Define SYSCALL_TRAP as trap #0.
* Remove def of SAVED_PC_AFTER_CALL (now in tm-m68k.h).
* gdbserver/low-lynx.c: Redo all register store/fetch stuff to
make it portable for 386 and 68k.
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.
* config/i386/tm-arm.h, config/i386/tm-i386aix.h,
config/i386/tm-sun386.h, config/i386/tm-symmetry.h,
config/m88k/tm-m88k.h config/rs6000/tm-rs6000.h (REGISTER_CONVERT_*):
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/a29k/tm-a29k.h, config/convex/tm-convex.h,
config/gould/tm-np1.h, config/gould/tm-pn.h, config/h8300/tm-h8300.h,
config/h8500/tm-h8500.h, config/i386/tm-i386v.h,

config/sh/tm-sh.h, config/sparc/tm-sparc.h, config/tahoe/tm-tahoe.h,
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.
* 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.

Use extract_floating and store_floating.
* config/m88k/tm-m88k.h: Add comments (it should be doing the same).

* remote-nindy.c (nindy_store_registers): Use store_floating.
* exec.c (ignore): Return 0.

VALUE_CONTENTS, to avoid "value computed is not used".
* inflow.c (new_tty): Move osigttou inside #if.

note that fact and keep going (reading extra registers as all bits 0).

by remote_fetch_registers.
* m68k-tdep.c, config/m68k/tm-m68k.h, config/m68k/tm-*.h: Remove
HAVE_68881. Define CANNOT_STORE_REGISTER if ptrace() can't write
floating registers.

Remove, replaced by {tm-m68k-em.h,m68k-em.mt}.
* Makefile.in, configure.in: Change accordingly.
* stabsread.c (define_symbol): Make the caddr_t hack apply to `function
returning foo' as well as `pointer to foo'.
* remote.c [REMOTE_BREAKPOINT]: Use for breakpoint insn if defined.
* config/m68k/tm-m68k.h: Define it.
* mem-break.c, breakpoint.c: Improve comments.
