#include "serial.h"
/* This structure describes the strings necessary to give small command
sequences to the monitor, and parse the response.
CMD is the actual command typed at the monitor. Usually this has
embedded sequences ala printf, which are substituted with the
arguments appropriate to that type of command. Ie: to examine a
register, we substitute the register name for the first arg. To
modify memory, we substitute the memory location and the new
contents for the first and second args, etc...
RESP_DELIM used to home in on the response string, and is used to
disambiguate the answer within the pile of text returned by the
monitor. This should be a unique string that immediately precedes
the answer. Ie: if your monitor prints out `PC: 00000001= ' in
response to asking for the PC, you should use `: ' as the
RESP_DELIM. RESP_DELIM may be NULL if the res- ponse is going to
be ignored, or has no particular leading text.
TERM is the string that the monitor outputs to indicate that it is
idle, and waiting for input. This is usually a prompt of some
sort. In the previous example, it would be `= '. It is important
that TERM really means that the monitor is idle, otherwise GDB may
try to type at it when it isn't ready for input. This is a problem
because many monitors cannot deal with type-ahead. TERM may be
NULL if the normal prompt is output.
TERM_CMD is used to quit out of the subcommand mode and get back to
the main prompt. TERM_CMD may be NULL if it isn't necessary. It
will also be ignored if TERM is NULL. */

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_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

if you are doing memory downloading.
This engages a new write function registered with dcache.

* Makefile.in (SUBDIRS): Add mswin so that make cleanup cleans up 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. * ser-e7kpc.c: Remove the last seven months of brain damage. Get rid of the DLL's since we can access the device directly from Win32s and Win95. Get rid of debugify crud. * serial.c: Remove debugify cruft. * (serial_logchar serial_log_command serial_write serial_readchar serial_send_break serial_close): Merge common functionality into serial_logchar. Clean up rest of routines. * sparclet-rom.c: Disembowel. Leave only download routine. Download routine now switches to remote target automatically. * top.c (disconnect): Only define if SIGHUP is defined. Cleans up MSVC/Win32 problem. * utils.c (gdb_flush): Don't call hook unless it's for gdb_stdout or gdb_stderr. * config/sh/tm-sh.h: Define TARGET_SH for WinGDB. * config/sparc/tm-sparclet.h: Remove override for prompt.

Wed Apr 29 10:20:40 1998 John Metzler <jmetzler@cygnus.com> * 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.
