(mips_initialize): LSI PMON doesn't support 'set regsize' command.
(pmon_wait): Don't need to exit and re-enter debug mode on LSI
PMON after a continue; it causes target program misbehavior.

cuts down on wasted serial traffic.
|
|
(find_proc_desc): Move non-heuristic proc search code into separate
function.
(gdb_print_insn_mips): Use non-heuristic method to find procedure
descriptor, to avoid prologue examination when disassembling.

occurs while exiting debug mode.

in the area of dealing with out-of-sequence packets.

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().

* 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. See above for descriptions.

NAT_FILE point directly at ../nm-sysv4.h.
* config/mips/{mipsm3.mh nm-m3.h}: Delete nm-m3.h. Make
NAT_FILE point directly at ../nm-m3.h.

Change GENERAL_MAGIC_HACKS to GENERAL_MAGIC.

TARGET_SYMFILE_POSTREAD and TARGET_CREATE_INFERIOR_HOOK.

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_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

structures (it conflicts with @!).

spot different prompts at run-time, so as to avoid having target

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.
