(mips_enter_debug, mips_exit_debug): New functions. (pmon_ops): New target definition structure. These changes provide the initial support for the PMON (3.0.83) monitor that appears on the Cogent (CMA101) Vr4300 development board. The changes do not affect the IDT monitor support, other than in the area of dealing with out-of-sequence packets.
1996-01-09 * remote-mips.c (mips_receive_header): Recognize \012 insteadStan Shebs1-1/+7
of \n, but write \n when program sends a \012. * ser-mac.c (mac_input_buffer): Increase size of buffer.
1995-12-07 * remote-mips.c (mips_receive_header): Allow mips_syn_garbage to beStu Grossman1-1/+12
user-settable (via set syn-garbage-limit). Setting it to -1 makes it unlimited.
1995-11-08 * remote-mips.c (mips_initialize): Fix brain damage found byStu Grossman1-2/+0
Jamie. Basically had case statement in the wrong place... * (mips_load): Remove unnecessary `db tty0' command. It's all handled by mips_initialize now.
1995-11-08 * remote-mips.c (mips_initialize): Fix brain damage found byStu Grossman1-5/+8
Jamie. Basically had case statement in the wrong place...
1995-11-07* remote-mips.c (mips_initialize): Updated to talk to VR4300 RISQJackie Smith Cashion1-14/+11
monitor board. The mips_initialize() code seemed to have a "funny" switch statement. I also removed an unnecessary switch into debug monitor mode just before the call to mips_initialize() in mips_load().
1995-11-04 * Makefile.in (INTERNAL_CFLAGS): Add ENABLE_CFLAGS.Stu Grossman1-46/+48
* fork-child.c (fork_inferior): Add call to TARGET_CREATE_INFERIOR_HOOK to allow target specific code to get control just before the new process executes it's first instruction. * remote-mips.c (mips_initialize): Cleanup a bit. Don't try to receive a packet at first. This speeds up initialization a lot. Use TARGET_MONITOR_PROMPT instead of "<IDT>". (common_breakpoint): Use rresponse instead of rerrflg to inspect error code. * symfile.c (syms_from_objfile reread_symbols): Call TARGET_SYMFILE_POSTREAD to allow target specific code to get control after reading new symbols. * target.h: New macros TARGET_SYMFILE_POSTREAD, and TARGET_CREATE_INFERIOR_HOOK.

Make NAT_FILE point directly at ../nm-m3.h. * config/mips/{mipsv4.mh nm-sysv4.h}: Delete nm-sysv4.h. Make NAT_FILE point directly at ../nm-sysv4.h. * config/mips/nm-mips.h: Improve comment at top of file. * config/mips/tm-mips.h (TARGET_MONITOR_PROMPT): Change definition into a proper string. start-sanitize-gm * configure configure.in: Add support for --enable-gm.

No longer necessary now that we use --enable mechanism. * config/mips/tm-idt.h: Add GM stuff needed for remote GM box. * config/mips/tm-irix5.h: Add GM stuff needed for native Irix box. * config/mips/tm-magic.h: Move up to config/tm-magic.h. Move all platform specific stuff into tm-irix.h and tm-idt.h. Add defs for TARGET_SYMFILE_POSTREAD and TARGET_CREATE_INFERIOR_HOOK. end-sanitize-gm
1995-10-27 * breakpoint.c (breakpoint_re_set): #ifdef GET_LONGJMP_TARGETStu Grossman1-59/+346
around calls to create_longjmp_breakpoint. Why install the breakpoints if we can't find the longjmp target? * infrun.c (wait_for_inferior): Cleanup comments near call test. * remote-mips.c: Fixed a bunch of prototypes to avoid char/int complaint from picky compilers. Add comment to mips_expect. Replace all instances of sr_get_debug with remote_debug. * (mips_readchar): Don't jam init string to monitor. mips_initialize() handles that. * (mips_receive_header): Print better message when we get too much garbage. * (mips_request): Allow caller to pass in buff to allow them to analyze the returned message. * (mips_initialize): Re-do initialization to try sending a BREAK, a ^C, and then a download escape sequence. Cleanup protocol startup. Eliminate sleeps. Clear breakpoints (if using monitor breakpoints). Re-init frame. * (mips_detach): Close down target. start-sanitize-gm * (mips_resume): Pass signal down to target. * (mips_create_inferior): Start target with TARGET_SIGNAL_PWR. end-sanitize-gm * (mips_wait): Handle return status with registers, or breakpoint stuff. * (mips_kill): Add ^C handling. * (mips_insert_breakpoint mips_remove_breakpoint): Call new breakpoint stuff if enabled. * (calculate_mask remote_mips_set_watchpoint remote_mips_remove_watchpoint remote_mips_stopped_by_watchpoint): Hardware watchpoint/breakpoint stuff. * (common_breakpoint): Common code for new monitor breakpoint commands. * (mips_load): Don't use `prompt'. It's a global variable. * top.c (dont_repeat_command): New command for use in user-defined commands to suppress auto-repeat (by hittin return key). start-sanitize-gm * utils.c (request_quit): Call target_kill here. Good idea. Needs a better implementation. end-sanitize-gm * valops.c: Add start of auto function-call abandonment capability. start-sanitize-gm * c-exp.y: Add code (currently disabled) to handle GM dynamic structures (it conflicts with @!). * eval.c (evaluate_subexp_standard): ditto. * expprint.c (print_subexp dump_expression): ditto. * expression.h (enum exp_opcode): ditto. * parse.c (length_of_subexp): ditto. * configure, configure.in: Add mip*-*-magic* target. * magic.c magic.h: Special routines to handle GM stuff (like stepping through dispatcher). end-sanitize-gm
1995-10-23The revision 2.48 change (grossman 1995/10/16) had unfortunatelyJackie Smith Cashion1-23/+17
broken the prompt spotting for the <RISQ> variant of the IDT monitor. Also took this opportunity to add the vr4300 configure.in options.
1995-10-16 * remote-mips.c: Add support for speedy (about 10x faster)Stu Grossman1-12/+298
downloads.
1995-09-01Ideally the "remote-mips.c" prompt spotting code should be updated toJackie Smith Cashion1-3/+9
spot different prompts at run-time, so as to avoid having target specific versions of gdb. This is a pending TODO. Fri Sep 1 08:25:50 1995 James G. Smith <jsmith@beauty.cygnus.com> * configure (mips64*vr4300*-*-elf): Support added. * remote-mips.c (mips_readchar): Change to allow build-time prompt string. * config/mips/tm-mips.h: Added TARGET_MONITOR_PROMPT. * config/mips/{vr4300.mt, vr4300el.mt, tm-vr4300.h, tm-vr4300el.h}: Added.

1995-07-13 * inftarg.c (child_thread_alive): New function to see if aJeff Law1-0/+1

(mywait): Don't restart any threads after a new thread notification, let the generic code handle it. * gdbserver/low-sparc.c (mythread_alive): Dummy version. * gdbserver/low-sun3.c (mythread_alive): Likewise. * gdbserver/server.c (main): Handle thread_alive requests. * gdbserver/server.h (mythread_alive): Declare. * corelow.c (core_ops): Add dummy entry for thread_alive. * exec.c (exec_ops): Likewise. * m3-nat.c (m3_ops): Likewise. * monitor.c (monitor_ops): Likewise. * procfs.c (procfs_ops): Likewise. * remote-arc.c (arc_ops): Likewise. * remote-array.c (array_ops): Likewise. * remote-e7000.c (e7000_ops): Likewise. * remote-es.c (es1800_ops, es1800_child_ops): Likewise. * remote-mips.c (mips_ops): Likewise. * remote-pa.c (remote_hppro_ops): Likewise. * remote-sim.c (gdbsim_ops): Likewise. * sparcl-tdep.c (sparclite_ops): Likewise. More lynx-6100 work
1995-06-08 * defs.h maint.c monitor.c remote-mips.c remote.c: Add supportStu Grossman1-4/+33
for `watchdog' variable. This allows the user to put an upper limit on the amount of time that GDB will wait for the target to return from a step or continue operation. This will primarily be used for the testsuite, where it is difficult to come up with a reasonable timeout for things like function calls, which can take as long as three minutes under some circumstances. If the watchdog timer expires, GDB will generate an error that looks like `Watchdog has expired.', and will detach from the target. * remote-mips.c (mips_open): Setup initial frame from target. Print it out so that user is told where the program is stopped when they attach. * remote-nrom.c: Loads of cleanups. Use serial code to open network connections. Use expect() to wait for response to download command. * ser-tcp.c (tcp_open): Retry connection if we get ECONNREFUSED. * serial.c serial.h (serial_open serial_fdopen serial_close): Allow users to open the same device multiple times. They all get to share the same serial_t. This is about the only way to have multiple active targets use the same device (for download and debug). * sparcl-tdep.c: Keep #include <unistd.h> away from GO32. * target.c: Add `targetdebug' variable. If this is non-zero, then a special target is put at the top of the target stack which will cause all calls through the target vector to have their args and results printed out.
