info.
* Implemented arch_set_cpu_state() (Axel, please check, what registers
the debugger should actually be allowed to modify).
* Fixed arch_get_cpu_state(). We now explicitly copy the registers
manually instead of using memcpy(). Added support for extended
registers (FPU,...).
* Completed break- and watchpoint support.
* Implemented handling of debug and breakpoint exceptions.
The x86 specific part of the userland debugging support should be complete
now. That is in theory the entire debugging interface is available on x86
machines now. It's almost completely untested yet, though.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@11526 a95241bf-73f2-0310-859d-f6bbb57e9c96
we only have 3 debug registers available for break-/watchpoints.
* Added definitions for debug status register DR6. Reordered DR7 defs to
ascending order. Added definitions for the EFLAGS flags we need.
* Added arch_thread_debug_info structure and related definitions.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@11525 a95241bf-73f2-0310-859d-f6bbb57e9c96
needed to get the topmost user iframe. Added i386_get_user_iframe() for
exactly that purpose.
* Added reinitialization of user debugging for the new thread when
switching the context.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@11523 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Made the parameter for restoring the FPU state const.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@11522 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Added event callbacks for break- and watchpoints and single stepping.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@11520 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Removed orig_e{a,d}x. We will always report those in e{a,d}x.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@11519 a95241bf-73f2-0310-859d-f6bbb57e9c96
functions for setting break-/watchpoints (implemented).
Break-/watchpoints don't work yet, though. Missing is still the setting
of the debug control register DR7 somewhere in the interrupt code and
the handling of debug exceptions.

debug infos.
* Added function for setting the CPU state.
* Added functions for setting break-/watchpoints.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@11507 a95241bf-73f2-0310-859d-f6bbb57e9c96
* In team_delete_team() we no longer explicitly destroy the team debug
info. It is not necessary, since the terminating debug nub thread will
do that anyway. Moreover we access the debugger port in a safer manner
now.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@11504 a95241bf-73f2-0310-859d-f6bbb57e9c96
by the team lock, but by a lock in the structure. This is necessary
since we can't acquire the team lock while thread switching, for then the
thread lock is already held.
* Added support for single stepping and break-/watchpoints.

to trim the templatized interface improves the situation, but we're still
quite heavy (400 KB).

(Daniel Furrer).
* The strace interface for the generated file changed.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@11495 a95241bf-73f2-0310-859d-f6bbb57e9c96
waiting for teams to crash to show our favorite alert.
Due to the missing app_server we don't show a alert yet. We just print
something to /dev/dprintf and kill the team. Unlike R5's debug server
ours will probably not provide any debugging functionality itself, but
rather employ gdb directly.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@11492 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Now a debugged thread and the debug nub thread are not longer blocking
on ports when they receive a SIGKILL[THR] (we couldn't kill a debugged
team before).
* Small fixes. More correct cleanup when the debug nub thread terminates.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@11491 a95241bf-73f2-0310-859d-f6bbb57e9c96
translation for the debug_why_stopped codes.
* Added nub_port member to debug_origin structure, so that now all
synchronous messages to the debugger also include the debug nub port.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@11489 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Added is_kill_signal_pending(). Can anyone tell me why the compiler
complains about a missing previous prototype for it? <ksignal.h> is
included, and when only preprocessing the file, the prototype is clearly
there. I'm clueless.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@11488 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Removed SIGKILLTHR from BLOCKABLE_SIGS.
* Made header C++ safe.
* Added function is_kill_signal_pending(), returning true, if a
SIGKILL[THR] is pending for the current thread.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@11487 a95241bf-73f2-0310-859d-f6bbb57e9c96
interruptable by SIGKILL[THR], even if B_CAN_INTERRUPT is not set. Not
sure, if this is the best solution, but it works.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@11484 a95241bf-73f2-0310-859d-f6bbb57e9c96
- If the thread's B_THREAD_DEBUG_STOP flag is set, it is now always
stopped before handling the signals. Unless a SIGKILL[THR] signal is
pending.
- Also notify the debugger, when a signal is ignored.
* The signal's sigaction structure is additionally passed to the debugger
now.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@11478 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Now we deal correctly with thread debug flags (child threads inherit
the parent ones, save for syscall tracing in which case it needs to
be specified explicitly).
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@11477 a95241bf-73f2-0310-859d-f6bbb57e9c96
In the first case this is probably too early, since the image is not
really loaded at that time by the loader. We should probably introduce
a syscall the loader can invoke for that purpose.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@11475 a95241bf-73f2-0310-859d-f6bbb57e9c96
convenience.
* Added/implemented callbacks for almost all missing debug events (team,
thread, image creation/deletion, exceptions/faults, signals).
* The debugger can now specify how to deal with the event that stopped an
event (ignore or handle signals, exceptions/faults).
* Implemented B_DEBUGGED_THREAD_GET_WHY_STOPPED debugger message.
* The cpu_state is now passed to the debugger with
B_DEBUGGER_MESSAGE_THREAD_STOPPED notifications.
* Completed _user_debugger() implementation.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@11474 a95241bf-73f2-0310-859d-f6bbb57e9c96
* team debug flags:
- Added flags for team creation, thread events (creation,
deletion), and image events (creation, deletion).
- Got rid of B_TEAM_DEBUG_SYSCALL_FAST_TRACE. We always send the syscall
arguments. The overhead should be neglectable.
- Added B_TEAM_DEBUG_STOP_NEW_THREADS.
* Added debugger notification messages for signals, team, thread and
image events.
* Added debug request B_DEBUG_MESSAGE_GET_WHY_STOPPED.
* When continuing a thread, the debugger can now specify how to deal with
the occurred event (ignore or handle).
* More data in the signal received notification message.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@11468 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Implemented finding programs in the PATH.
* Added human readable error codes for status_t and ssize_t return values.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@11448 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Now syscall names and parameters are printed. const char* parameters
and return values are retrieved from the client and printed as string.
* Missing are still color output (does consoled support that?) and
searching for given commands in the PATH. Nothing besides the standard
mode has been tested yet, so it's probably not working.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@11345 a95241bf-73f2-0310-859d-f6bbb57e9c96
* The syscall arguments are copied into the respective messages to the
debugger now.
* Optimized the nub thread memory reading command. Now only as many bytes
are sent to the debugger as were actually read.

pointers and overall parameters size for the kernel and some more
sophisticated code for strace.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@11339 a95241bf-73f2-0310-859d-f6bbb57e9c96
a respective message, when the debugged team has been deleted.

Unless a good reason appears not to, we'll break binary compatibility here.
BDB could be considered one, but we need a replacement for it anyway. We
strive to port GDB and a couple of changes in the debugger API will make
that easier.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@11307 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Removed ARM support.
* Removed PEF references.
* Added structure and constants for pre syscall tracing.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@11245 a95241bf-73f2-0310-859d-f6bbb57e9c96
notify_listener() and send_notification() can be dropped.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@11219 a95241bf-73f2-0310-859d-f6bbb57e9c96
link member in the element class. Usually more comfortable for structs.
* Added Add() method as synonym for Insert().
* Made fGetLink member static to save memory in objects using it.
