Mon Sep 13 14:14:35 1993 K. Richard Pixley (rich@sendai.cygnus.com)
Collect some remote things into remote-utils.
* remote-utils.[ch]: new files of functions collected from several
different remote targets.
* Makefile.in (REMOTE_O): add remote-utils.o.
(dcache_h, remote_utils_h): new macros.
(HFILES): add $(remote_utils_h).
(ALLDEPFILES): add $(remote_utils_h).
(dcache.o): new rule.
(main.o, remote-bug.o): also depend on $(remote_utils_h).
* target.h (remote_debug): extern moved to remote-utils.h.
* target.c (find_default_run_target, find_core_target): initialize
runable.
(remote_debug): moved to remote-utils.c.
(_initialize_targets): move declaration of user variable
remotedebug to remote-utils.c.
* remote-bug.c: include remote-utils.h rather than dcache.h.
(bug_close, bug_write, bug_write_cr, desc, bug_dcache, timeout,
dev_name, check_open, is_open, readchar, readchar_nofail,
pollchar, expect, expect_prompt, get_hex_digit, get_hex_byte,
get_hex_word, bug_kill, bug_detach, bug_create_inferior,
multi-scan, bug_prepare_to_store, bug_fetch_word,
bug_store_word, bug_files_info, bug_mourn, bug_com, bug_device,
bug_speed): removed and replaced with facilities from
remote-utils.[ch].
(bug_read_inferior_memory): renamed to bug_read_memory.
(bug_write_inferior_memory): renamed to bug_write_memory.
(bug_xfer_inferior_memory): renamed to bug_xfer_memory.
(get_word): comment out this unused function for now.
(bug_settings, cpu_check_strings): new statics.
(bug_open): rewritten to use gr_open.
(_initialize_remote_bug): remove declarations of commands bug,
device, speed.
* main.c: include remote-utils.h.
(baud_rate): removed to remote-utils.c.
(main): handle baud rate settings using new facilities from
remote-utils.
* defs.h (baud_rate): removed extern.
m88110 support via bug-197 monitor.
* remote-bug.c (get_reg_name, bug_fetch_register,
bug_store_register): added m88110 extended register support.
(wait_strings): added bug-197 prompt.
(bug_wait): cope with bug-197 prompt.
(start_load): cope with either bug-197 or bug-187 prompt.
Mon Sep 13 12:53:09 1993 Jim Kingdon (kingdon@cirdan.cygnus.com)
* inferior.h, infrun.c, thread.c, infcmd.c: Remove all uses of

are packaged together in this one file because they are typically
used together.
The first package is an addition to the serial package. The
addition provides reading and writing with debugging output and
timeouts based on user settable variables. These routines are
intended to support serial port based remote backends. These
functions are prefixed with sr_.
The second package is a collection of more or less generic
functions for use by remote backends. They support user settable
variables for debugging, retries, and the like.
Todo:
* a pass through mode a la kermit or telnet.
* autobaud.

The convention for dealing with the prompt is that you
o give your command
o *then* wait for the prompt.
Thus the last thing that a procedure does with the serial line
will be an gr_expect_prompt(). Exception: resume does not
wait for the prompt, because the terminal is being handed over
to the inferior. However, the next thing which happens after that
is a bug_wait which does wait for the prompt.
Note that this includes abnormal exit, e.g. error(). This is
necessary to prevent getting into states from which we can't
recover. */
