* nec4102rom.c : New file implements rom monitor adapter for
nec-vr4102 board. This board hosts the vr4111 chip. This file
required extenstions to the monitor_ops structure, hooks for wiat
filter, new flags. This version does not support more than one
breakpoint and resuming after a breakpoint in 16 bit mode is
completely disfunctional. * monitor.h : Defined additional hooks
for dmpregs, confinuer_hooks and wait_filter. These additions
require that all rom monitor interfaces be recoded to to
initializa monitor ops using assignments rather than static
structure initialization. Added new bits to flags
MO_EXACT_DUMPADDR, MO_HAS_BLOCKWRITES
* monitor.c (RDEBUG): Conditional tracing throughout the file.
(fromhex): Now recognized upper cse hex digits
(monitor_printf_noecho):
(monitor_readchar): Tracing interferes with input timing.
(monitor_open): Register different memory write functions with
dcache_init if MO_HAS_BLOCKWRITES.
(flush_monior_dcache): Added as an additional utilty.
(monitor-resume): Call continue hook if one has been supplied.
(monitor_wait_filter): New function Factored out of monitor wait
and used if alternate wait-filter has not been provided.
(monitor_wait): call alternate wait filter if provided. Call
monitor_dump_regs, a new function factored out from inline code.
(monitor_dump_block): A new function used as a utility when
monitors must dump several blocks of registers using different
commands.
(monitor_dump_regs): Call alternate function if provided. Uses new
hook in monitor.h.
(monitor_write_memory): Engage previouly added hook
MO_FILL_USES_ADDR.
(monitor_write_even_block): new function supports writing long
blocks of 4byte words.
(longlongendswap): new internal function
(monitor_write_memory_longlongs): new function writes large blocks
using command to enter a long long.
(monitor_write-memory_block): new Function figures out which block
mod to use.
(monitor_read_memory): Can now handle dump formats in which the bytes
preceeding the requested data is not printed.
* monitor.h: Added new fields to the structure
* monitor.c (monitor_debug): Move to utils.c, rename to puts_debug.
(monitor_write_memory, monitor_read_memory, monitor_insert_breakpoint,
monitor_remove_breakpoint): Remove useless address bits if current
monitor has MO_ADDR_BITS_REMOVE flag.
* monitor.h (MO_ADDR_BITS_REMOVE): Define.
* utils.c (puts_debug): Formerly monitor_debug from monitor.c;
move here and make public. Add better support for carriage returns.
* defs.h (puts_debug): Declare.
* dsrec.c (load_srec): Use puts_debug to print remotedebug information.
Output header record correctly.
(make_srec): Output a header record instead of a termination record
if sect is non-NULL (value is ignored), but abfd is NULL.
* config/mips/tm-tx39.h (DEFAULT_MIPS_TYPE): Remove definition.
(REGISTER_NAMES): Define to add R3900-specific registers.
* config/mips/tm-tx39l.h: Ditto.
* config/mips/tx39.mt (TDEPFILES): Add dve3900-rom.o and support files.
* config/mips/tx39l.mt: Ditto.
that directory.
* defs.h utils.c (error warning): Make message be const.
* main.c (fputs_unfiltered): Only send gdb_stdout and gdb_stderr
to hook. Otherwise send it to fputs.
* monitor.c monitor.h (monitor_get_dev_name): New function. Does
the obvious.
* remote-e7000.c: Remove debugify stuff. Change printf, fprintf
to _filtered forms to make output appear in GUIs. Replace all
uses of SERIAL_READCHAR with readchar, which has better error
checking.
* (e7000_parse_device): Add prototype.
* (readchar): Improve doc. Handle random serial errors.
* (expect): Disable notice_quit code. It's busted. Remove
serial error handling (it's now handled in readchar). Remove
remote_debug echoing. That's handled in readchar as well.
* (e7000_parse_device): Remove serial_flag arg. It's not
necessary.
* (e7000_open): Split into two pieces. Second part is
e7000_start_remote, and is error protected. Now, when we connect
to the target, we setup the initial frame and registers so that
the user gets an immediate indication of where the target is.
* (gch): Remove debug output. That's handled by readchar.
* (e7000_read_inferior_memory): Handle errors better.
* (_initialize_remote_e7000): Get rid of `<xxx>' things from
command names. They show up when doing completion and confuse
things horribly.

or gdb_stderr.
* config/sh/tm-sh.h: Define TARGET_SH for WinGDB.
* config/sparc/tm-sparclet.h: Remove override for prompt.
* m32r-tdep.c: Improved frame_chain and fn prologue analysis.
* configure.tgt: Add entry for m32r target.
* monitor.h: Add a flag to tell monitor_store_register to use
(val, regno) instead of (regno, val).
* monitor.c: Make monitor_store_register honor the above flag.
Make monitor_exp ignore DC1/DC3 for m32r.
Increase buf size in monitor_dump_regs.
* monitor.h,monitor.c:
Added monitor flags MO_NO_ECHO_ON_SETMEM (don't expect echo on
setmem command), MO_RUN_FIRST_TIME (if command to start process
running on target is different from one to continue execution),
MO_HEX_PREFIX (if addresses from monitor have a "0x" prefix).
* monitor.c,parse.c,sparc-tdep.c:
Don't require strings in the registers array. This is to allow
NULLs to be place holders in the tm-*.h file so that only minor
changes are needed when a new processor is introduced (eg, one
without floating point).
* sparc-tdep.c: Conditionally remove dependancies on floating point.
* sparclet-rom.c,config/sparc/sparclet.mt,config/sparc/tm-sparclet.h:

that had too many arguments.
* (unwind_command): Clean it up and make it print things out
nicer.

remote.c).
* (monitor_printf): Make it check the command echo.
* (monitor_printf_noecho): Similar to above, but doesn't check
for echo.
* (monitor_stop): No longer waits for prompt. That is the job of
the caller. This makes things work much better for monitor_wait,
which waits for the prompt itself.
* (monitor_open): Deal with new monitor_stop semantics. Also,
flush input after sending init strings to get rid of junk that may
be output. Also, don't always send \r to remote. Use
monitor_ops->line_term cuz proper character isn't always \r.
* (monitor_fetch_register): Switch to completely different
algorithm to deal with lame-ass monitors which put spaces in the
middle of numbers, and prompt with a space!!!!!
* (monitor_read_memory_single): New routine to be used with
monitors that can only return one byte/short/long at a time. This
is selected via MO_GETMEM_READ_SINGLE.

target doesn't support signals.
* findvar.c: Move default def of CANNOT_STORE_REGISTER closer to
the beginning of the code.

read_register_gen.
* (write_register_bytes): Another rewrite! Make it smarter about
not updating regs with the same value.

regs for those targets which don't do so when waking up after a
continue command.
* (monitor_wait): Handle excessive response output better.

commands (if they exist) to write memory more efficiently.
* General cleanups to use flag bits instead of individual flag
words in monitor_ops struct.
* (monitor_command): Return output from command.
* (monitor_load_srec): Allocate buffer only once. Use alloca.
Wait for load response string instead of using a timeout to start
sending S-records. Fix bug where value of srec_frame shrinks. If
hashmark is set, print `-' for retransmissions. General cleanups.
* (monitor_make_srec): Get rid of S-record default type kludge.
