* remote.c: Make it work for embedded MIPS. Increase buffer size, and use throughout. Round buffer size up if too many regs. Support baud rate setting and try for an 8-bit path. If interrupted while waiting for target, send a ^C down the wire. Avoid single-byte reads. * tm-mips.h: Add more embedded-system registers to REGISTER_NAMES and NUM_REGS. * mips-xdep.h: Avoid the embedded regs when on Unix.

/* Remote target communications for serial-line targets in custom GDB protocol
Thu Oct 29 10:04:20 1998 Michael Snyder <msnyder@cleaver.cygnus.com> [Support for trace debugging: registers that were not collected.] * remote.c (remote_fetch_registers): accept 'xxxx' in the register packet, with the meaning "register value is not available". Set register_valid to -1, which will connote "no value available". * findvar.c (read_relative_register_raw_bytes): return failure if register_valid == -1.

Also save the bfd section. (tracepoints_info): use the section when looking up the function name. * tracepoint.h: add section field to tracepoint struct.

CSUM1 and CSUM2 are ascii hex representation of an 8-bit
checksum of <data>, the most significant nibble is sent first.
the hex digits 0-9,a-f are used.
Receiver responds with:
+ - if CSUM is correct and ready for next packet

* remote.c: Make it work for embedded MIPS. Increase buffer size, and use throughout. Round buffer size up if too many regs. Support baud rate setting and try for an 8-bit path. If interrupted while waiting for target, send a ^C down the wire. Avoid single-byte reads. * tm-mips.h: Add more embedded-system registers to REGISTER_NAMES and NUM_REGS. * mips-xdep.h: Avoid the embedded regs when on Unix.

/* The target vector does not have the thread functions in it yet,
so we use this function to call back into the thread module and
register the thread vector and its contained functions. */
* remote.c: Pacify --enable-build-warnings, reformat code to conform to standards, fix spelling errors. (ishex, stubhex, record_currthread, etc): Declare. (ishex, stubhex): Declare char arg as int. (pack_string): Comment out, never used but possibly useful. (threadref_to_int, remote_get_threadinfo, etc): Make static.

/* Start out by trying the 'P' request to set registers. We set
this each time that we open a new target so that if the user
switches from one stub to another, we can (if the target is
closed and reopened) cope. */
* remote.c (remote_store_registers): Add 'P' request to set an individual register. (remote_write_bytes, remote_read_bytes): Use %lx, not %x, to print a target address.
1994-03-30 04:43:48 +08:00
stub_supports_P = 1;
* gdbserver/remote-utils.c (write_ok): Write "OK", not "Ok", to match stubs and protocol spec. * gdbserver/remote-utils.c (remote_open): Cast to struct sockaddr when passing to function which expects that. The following changes aren't quite enough to make things work with LynxOS (apprently kernel problems). * infrun.c (wait_for_inferior): When resuming new thread, pass pid not -1 for remote case. * thread.c (info_threads_command): Give error if !target_has_stack. * infrun.c (start_remote): Call init_thread_list. * thread.c (info_threads_command): Don't call kill for remote debugging target. * target.c (normal_pid_to_str): Print "thread" not "process" for remote. * remote.c, gdbserver/*: Add 'H', 'S', and 'C' requests, 'X' response, and `thread' part of 'T' response. * gdbserver/*: If program exits, send packet to GDB before exiting. Handle termination with a signal the same as exiting with an exitstatus. * remote.c: Don't try to kill program after getting an 'X' response. * infrun.c (wait_for_inferior): Add comment about kill versus mourn.

/* Without this, some commands which require an active target (such
as kill) won't work. This variable serves (at least) double duty
as both the pid of the target process (if it has such), and as a
flag indicating that a target is active. These functions should
be split out into seperate variables, especially since GDB will
someday have a notion of debugging several processes. */
* remote.c (remote_open): Set inferior_pid to make kill command happy. * inflow.c (kill_command): Revert change of Aug 2. Use inferior_pid to determine whether to print out "The program is not being run." message.
1994-08-05 01:32:09 +08:00
* remote.c (record_curthread): Must not modify inferior_pid when called from wait_for_inferior. Instead, if a new thread-id is detected, call add_thread. (MAGIC_NULL_PID): new macro, use instead of the magic number "42000". (remote_find_new_threads): if inferior_pid is unknown, get and use the current thread id. (remote_start_remote): on connecting, attempt to get the current thread id for inferior_pid. (remote_resume): If pid == -1, then resume any-thread (not the current thread specifically). * thread.c (info_threads_command): don't initialize current_pid until after call to FIND_NEW_THREADS (which may change inferior_pid).
1999-01-06 11:08:10 +08:00
inferior_pid = MAGIC_NULL_PID;

/* Start the remote connection; if error (0), discard this target.
In particular, if the user quits, be sure to discard it
(we'd be in an inconsistent state otherwise). */
Tue Jan 26 16:53:54 1999 Fernando Nasser <fnasser@cygnus.com> * remote.c (remote_query): fix maximum packet size to account for remote_debug use. (putpkt): add comment to alert about extra byte need.

* Makefile.in (init.c): Generate using the source, not munch. This cleans up all kinds of hassles (which nm to use in munch, etc). The new formatting conventions (mostly already followed) are that the name of the _initialize_* routines must start in column zero, and must not be inside #if. * munch: Removed. * Makefile.in: Remove references to munch. * serial.c, remote.c, infptrace.c, maint.c, convex-tdep.c, alpha-tdep.c, hp300ux-nat.c, hppab-nat.c, osfsolib.c, remote-es.c, procfs.c, remote-udi.c, ser-go32.c, ultra3-xdep.c, sh-tdep.c, i960-tdep.c, hppa-tdep.c, h8500-tdep.c, dpx2-nat.c, delta68-nat.c, z8k-tdep.c: Make sure the above conventions are followed. Make sure they are all declared as returning void. Clean up miscellaneous comments and such.
