Waiting for events in sync mode
|
|
|
|
|
===============================
|
|
|
|
|
|
|
|
|
|
When waiting for an event in a specific thread, we just use waitpid, passing
|
|
|
|
|
the specific pid, and not passing WNOHANG.
|
|
|
|
|
|
|
|
|
|
When waiting for an event in all threads, waitpid is not quite good. Prior to
|
|
|
|
|
version 2.4, Linux can either wait for event in main thread, or in secondary
|
|
|
|
|
threads. (2.4 has the __WALL flag). So, if we use blocking waitpid, we might
|
|
|
|
|
miss an event. The solution is to use non-blocking waitpid, together with
|
|
|
|
|
sigsuspend. First, we use non-blocking waitpid to get an event in the main
|
|
|
|
|
process, if any. Second, we use non-blocking waitpid with the __WCLONED
|
|
|
|
|
flag to check for events in cloned processes. If nothing is found, we use
|
|
|
|
|
sigsuspend to wait for SIGCHLD. When SIGCHLD arrives, it means something
|
|
|
|
|
happened to a child process -- and SIGCHLD will be delivered both for events
|
|
|
|
|
in main debugged process and in cloned processes. As soon as we know there's
|
|
|
|
|
an event, we get back to calling nonblocking waitpid with and without __WCLONED.
|
|
|
|
|
|
|
|
|
|
Note that SIGCHLD should be blocked between waitpid and sigsuspend calls,
|
|
|
|
|
so that we don't miss a signal. If SIGCHLD arrives in between, when it's
|
|
|
|
|
blocked, the signal becomes pending and sigsuspend immediately
|
|
|
|
|
notices it and returns.
|
|
|
|
|
|
|
|
|
|
Waiting for events in async mode
|
|
|
|
|
================================
|
|
|
|
|
|
2009-05-11 12:08:03 +00:00
|
|
|
|
In async mode, GDB should always be ready to handle both user input
|
|
|
|
|
and target events, so neither blocking waitpid nor sigsuspend are
|
|
|
|
|
viable options. Instead, we should asynchronously notify the GDB main
|
|
|
|
|
event loop whenever there's an unprocessed event from the target. We
|
|
|
|
|
detect asynchronous target events by handling SIGCHLD signals. To
|
|
|
|
|
notify the event loop about target events, the self-pipe trick is used
|
|
|
|
|
--- a pipe is registered as waitable event source in the event loop,
|
|
|
|
|
the event loop select/poll's on the read end of this pipe (as well on
|
|
|
|
|
other event sources, e.g., stdin), and the SIGCHLD handler writes a
|
|
|
|
|
byte to this pipe. This is more portable than relying on
|
|
|
|
|
pselect/ppoll, since on kernels that lack those syscalls, libc
|
|
|
|
|
emulates them with select/poll+sigprocmask, and that is racy
|
|
|
|
|
(a.k.a. plain broken).
|
|
|
|
|
|
|
|
|
|
Obviously, if we fail to notify the event loop if there's a target
|
|
|
|
|
event, it's bad. OTOH, if we notify the event loop when there's no
|
|
|
|
|
event from the target, linux_nat_wait will detect that there's no real
|
|
|
|
|
event to report, and return event of type TARGET_WAITKIND_IGNORE.
|
|
|
|
|
This is mostly harmless, but it will waste time and is better avoided.
|
|
|
|
|
|
|
|
|
|
The main design point is that every time GDB is outside linux-nat.c,
|
|
|
|
|
we have a SIGCHLD handler installed that is called when something
|
|
|
|
|
happens to the target and notifies the GDB event loop. Whenever GDB
|
|
|
|
|
core decides to handle the event, and calls into linux-nat.c, we
|
|
|
|
|
process things as in sync mode, except that the we never block in
|
|
|
|
|
sigsuspend.
|
|
|
|
|
|
|
|
|
|
While processing an event, we may end up momentarily blocked in
|
|
|
|
|
waitpid calls. Those waitpid calls, while blocking, are guarantied to
|
|
|
|
|
return quickly. E.g., in all-stop mode, before reporting to the core
|
|
|
|
|
that an LWP hit a breakpoint, all LWPs are stopped by sending them
|
|
|
|
|
SIGSTOP, and synchronously waiting for the SIGSTOP to be reported.
|
|
|
|
|
Note that this is different from blocking indefinitely waiting for the
|
|
|
|
|
next event --- here, we're already handling an event.

|
Use of signals
|
|
|
|
|
==============
|
|
|
|
|
|
|
|
|
|
We stop threads by sending a SIGSTOP. The use of SIGSTOP instead of another
|
|
|
|
|
signal is not entirely significant; we just need for a signal to be delivered,
|
|
|
|
|
so that we can intercept it. SIGSTOP's advantage is that it can not be
|
|
|
|
|
blocked. A disadvantage is that it is not a real-time signal, so it can only
|
|
|
|
|
be queued once; we do not keep track of other sources of SIGSTOP.
|
|
|
|
|
|
|
|
|
|
Two other signals that can't be blocked are SIGCONT and SIGKILL. But we can't
|
|
|
|
|
use them, because they have special behavior when the signal is generated -
|
|
|
|
|
not when it is delivered. SIGCONT resumes the entire thread group and SIGKILL
|
|
|
|
|
kills the entire thread group.
|
|
|
|
|
|
|
|
|
|
A delivered SIGSTOP would stop the entire thread group, not just the thread we
|
|
|
|
|
tkill'd. But we never let the SIGSTOP be delivered; we always intercept and
|
|
|
|
|
cancel it (by PTRACE_CONT without passing SIGSTOP).
|
|
|
|
|
|
|
|
|
|
We could use a real-time signal instead. This would solve those problems; we
|
|
|
|
|
could use PTRACE_GETSIGINFO to locate the specific stop signals sent by GDB.
|
|
|
|
|
But we would still have to have some support for SIGSTOP, since PTRACE_ATTACH
|
|
|
|
|
generates it, and there are races with trying to find a signal that is not
|
|
|
|
|
blocked. */

* linux-nat.c (linux_child_follow_fork): If we're staying attached
to the child process, enable event reporting on it. Don't handle
checkpoints here. Instead, add the child fork to the lwp thread
and inferior lists without clobbering the previous inferior. Let
the thread_db layer learn about a new child process, even if
following the parent.
(linux_nat_switch_fork): Delete lwps of the current inferior only,
instead of clearing the whole list. Use thread_change_ptid to
give the core the illusion the new checkpoint is still the same
inferior. Clear the register cache.
(linux_handle_extended_wait): Handle checkpoints here.
(linux_multi_process): Turn on.
* linux-fork.c (struct fork_info) <pc>: Remove field.
(init_fork_list): Do not delete the checkpoint from the inferior
list (it is not there).
(fork_load_infrun_state): Don't switch inferior_ptid here. Pass
the new checkpoint's ptid to linux_nat_switch_fork.
(fork_save_infrun_state): Make static. Don't stop the pc field of
fork_info, it's gone.
(linux_fork_mourn_inferior): Don't delete the checkpoint from the
inferior list, it's not there.
(linux_fork_detach): Ditto.
(delete_fork_command): Replace mention of fork/checkpoint by
checkpoint only.
(detach_fork_command): Likewise. Don't delete the checkpoint from
the inferior list.
(info_forks_command): Adjust.
(restore_detach_fork): Delete.
(checkpointing_pid): New.
(linux_fork_checkpointing_p): New.
(save_detach_fork): Delete.
(checkpoint_command): Delete temp_detach_fork. Don't remove
breakpoints, that's a nop. Store the pid of the process we're
checkpointing, and use make_cleanup_restore_integer to restore it.
Don't reinsert breakpoints here.
(process_command, fork_command): Delete.
(restart_command): Update comments to only mention checkpoints,
not forks.
(_initialize_linux_fork): Delete "fork", "process", "info forks"
commands.
* linux-fork.h (fork_save_infrun_state, fork_list): Delete
declarations.

(inferior_command): New.
(info_inferiors_command): Allow specifying a specific inferior id.
(_initialize_inferiors): Register "inferior", "kill inferior" and
"detach inferior" commands.
* infcmd.c (_initialize_infcmd): Make "kill" a prefix command.
* gdbthread.h (any_thread_of_process): Declare.
* thread.c (any_thread_of_process): New.
* NEWS: Mention multi-inferior debugging. Mention 'info
inferiors', 'inferior', 'detach inferior' and 'kill inferior' as
new commands.
(Removed commands): New section, mentioning that 'info forks',
'fork', 'process', 'delete fork' and 'detach fork' are now gone.
gdb/testsuite/
2009-07-02 Pedro Alves <pedro@codesourcery.com>
* gdb.base/multi-forks.exp: Only run detach-on-fork tests on
linux. Adjust to use "inferior", "info inferiors", "detach
inferior" and "kill inferior" instead of "restart", "info fork",
"detach fork" and "delete fork".
* gdb.base/ending-run.exp: Spell out "info".
* gdb.base/help.exp: Adjust to use test_prefix_command_help for
the "kill" command.
gdb/doc/
2009-07-02 Pedro Alves <pedro@codesourcery.com>
* gdb.texinfo (Debugging multiple inferiors): Document the
"inferior", "detach inferior" and "kill inferior" commands.
(Debugging Programs with Multiple Processes): Adjust to mention
generic "inferior" commands. Delete mention of "detach fork" and
"delete fork". Cross reference to "Debugging multiple inferiors"
section.

First, we try to enable fork tracing on ORIGINAL_PID. If this fails,

we know that the feature is not available. This may change the tracing

|
|

|
|
However, if it succeeds, we don't know for sure that the feature is
|
|
|
|
|
available; old versions of PTRACE_SETOPTIONS ignored unknown options. We
|
2003-06-15 20:56:48 +00:00

create a child process, attach to it, use PTRACE_SETOPTIONS to enable

|
|
|
|
fork tracing, and let it fork. If the process exits, we assume that we

|
|
|
|
can't use TRACEFORK; if we get the fork notification, and we can extract
|
|

the new child's PID, then we assume that we can. */

* linux-nat.c (linux_child_follow_fork): If we're staying attached
to the child process, enable event reporting on it. Don't handle
checkpoints here. Instead, add the child fork to the lwp thread
and inferior lists without clobbering the previous inferior. Let
the thread_db layer learn about a new child process, even if
following the parent.
(linux_nat_switch_fork): Delete lwps of the current inferior only,
instead of clearing the whole list. Use thread_change_ptid to
give the core the illusion the new checkpoint is still the same
inferior. Clear the register cache.

checkpointing, and use make_cleanup_restore_integer to restore it.
Don't reinsert breakpoints here.
(process_command, fork_command): Delete.

inferior" and "kill inferior" instead of "restart", "info fork",
"detach fork" and "delete fork".
* gdb.base/ending-run.exp: Spell out "info".
* gdb.base/help.exp: Adjust to use test_prefix_command_help for
the "kill" command.

2009-07-02 Pedro Alves <pedro@codesourcery.com>
* linux-nat.c (linux_child_follow_fork): If we're staying attached
to the child process, enable event reporting on it. Don't handle
checkpoints here. Instead, add the child fork to the lwp thread
and inferior lists without clobbering the previous inferior. Let
the thread_db layer learn about a new child process, even if
following the parent.
(linux_nat_switch_fork): Delete lwps of the current inferior only,
instead of clearing the whole list. Use thread_change_ptid to
give the core the illusion the new checkpoint is still the same
inferior. Clear the register cache.

/* We can't insert breakpoints until the child has
|
|
|
|
|
finished with the shared memory region. We need to
|
|
|
|
|
wait until that happens. Ideal would be to just
|
|
|
|
|
call:
|
|
|
|
|
- ptrace (PTRACE_SYSCALL, parent_pid, 0, 0);
|
|
|
|
|
- waitpid (parent_pid, &status, __WALL);
|
|
|
|
|
However, most architectures can't handle a syscall
|
|
|
|
|
being traced on the way out if it wasn't traced on
|
|
|
|
|
the way in.
|
|
|
|
|
|
|
|
|
|
We might also think to loop, continuing the child
|
|
|
|
|
until it exits or gets a SIGTRAP. One problem is
|
|
|
|
|
that the child might call ptrace with PTRACE_TRACEME.
|
|
|
|
|
|
|
|
|
|
There's no simple and reliable way to figure out when
|
|
|
|
|
the vforked child will be done with its copy of the
|
|
|
|
|
shared memory. We could step it out of the syscall,
|
|
|
|
|
two instructions, let it go, and then single-step the
|
|
|
|
|
parent once. When we have hardware single-step, this
|
|
|
|
|
would work; with software single-step it could still
|
|
|
|
|
be made to work but we'd have to be able to insert
|
|
|
|
|
single-step breakpoints in the child, and we'd have
|
|
|
|
|
to insert -just- the single-step breakpoint in the
|
|
|
|
|
parent. Very awkward.
|
|
|
|
|
|
|
|
|
|
In the end, the best we can do is to make sure it
|
|
|
|
|
runs for a little while. Hopefully it will be out of
|
|
|
|
|
range of any breakpoints we reinsert. Usually this
|
|
|
|
|
is only the single-step breakpoint at vfork's return
|
|
|
|
|
point. */

* linux-nat.c (linux_child_follow_fork): If we're staying attached
to the child process, enable event reporting on it. Don't handle
checkpoints here. Instead, add the child fork to the lwp thread
and inferior lists without clobbering the previous inferior. Let
the thread_db layer learn about a new child process, even if
following the parent.
(linux_nat_switch_fork): Delete lwps of the current inferior only,
instead of clearing the whole list. Use thread_change_ptid to
give the core the illusion the new checkpoint is still the same
inferior. Clear the register cache.

(linux_multi_process): Turn on.
* linux-fork.c (struct fork_info) <pc>: Remove field.
(init_fork_list): Do not delete the checkpoint from the inferior
list (it is not there).

breakpoints, that's a nop. Store the pid of the process we're
checkpointing, and use make_cleanup_restore_integer to restore it.
Don't reinsert breakpoints here.
(process_command, fork_command): Delete.
(restart_command): Update comments to only mention checkpoints,
not forks.

linux. Adjust to use "inferior", "info inferiors", "detach
inferior" and "kill inferior" instead of "restart", "info fork",
"detach fork" and "delete fork".

* gdb.base/help.exp: Adjust to use test_prefix_command_help for
the "kill" command.

/* On GNU/Linux there are no real LWP's. The closest thing to LWP's
|
|
|
|
|
are processes sharing the same VM space. A multi-threaded process
|
|
|
|
|
is basically a group of such processes. However, such a grouping
|
|
|
|
|
is almost entirely a user-space issue; the kernel doesn't enforce
|
|
|
|
|
such a grouping at all (this might change in the future). In
|
|
|
|
|
general, we'll rely on the threads library (i.e. the GNU/Linux
|
|
|
|
|
Threads library) to provide such a grouping.
|
|
|
|
|
|
|
|
|
|
It is perfectly well possible to write a multi-threaded application
|
|
|
|
|
without the assistance of a threads library, by using the clone
|
|
|
|
|
system call directly. This module should be able to give some
|
|
|
|
|
rudimentary support for debugging such applications if developers
|
|
|
|
|
specify the CLONE_PTRACE flag in the clone system call, and are
|
|
|
|
|
using the Linux kernel 2.4 or above.
|
|
|
|
|
|
|
|
|
|
Note that there are some peculiarities in GNU/Linux that affect
|
|
|
|
|
this code:
|
|
|
|
|
|
|
|
|
|
- In general one should specify the __WCLONE flag to waitpid in
|
|
|
|
|
order to make it report events for any of the cloned processes
|
|
|
|
|
(and leave it out for the initial process). However, if a cloned
|
|
|
|
|
process has exited the exit status is only reported if the
|
|
|
|
|
__WCLONE flag is absent. Linux kernel 2.4 has a __WALL flag, but
|
|
|
|
|
we cannot use it since GDB must work on older systems too.
|
|
|
|
|
|
|
|
|
|
- When a traced, cloned process exits and is waited for by the
|
|
|
|
|
debugger, the kernel reassigns it to the original parent and
|
|
|
|
|
keeps it around as a "zombie". Somehow, the GNU/Linux Threads
|
|
|
|
|
library doesn't notice this, which leads to the "zombie problem":
|
|
|
|
|
When debugged a multi-threaded process that spawns a lot of
|
|
|
|
|
threads will run out of processes, even if the threads exit,
|
|
|
|
|
because the "zombies" stay around. */

* linux-nat.c (linux_child_follow_fork): If we're staying attached
to the child process, enable event reporting on it. Don't handle
checkpoints here. Instead, add the child fork to the lwp thread
and inferior lists without clobbering the previous inferior. Let
the thread_db layer learn about a new child process, even if
following the parent.
(linux_nat_switch_fork): Delete lwps of the current inferior only,
instead of clearing the whole list. Use thread_change_ptid to
give the core the illusion the new checkpoint is still the same
inferior. Clear the register cache.
(linux_handle_extended_wait): Handle checkpoints here.
(linux_multi_process): Turn on.
* linux-fork.c (struct fork_info) <pc>: Remove field.
(init_fork_list): Do not delete the checkpoint from the inferior
list (it is not there).
(fork_load_infrun_state): Don't switch inferior_ptid here. Pass
the new checkpoint's ptid to linux_nat_switch_fork.
(fork_save_infrun_state): Make static. Don't stop the pc field of
fork_info, it's gone.
(linux_fork_mourn_inferior): Don't delete the checkpoint from the
inferior list, it's not there.
(linux_fork_detach): Ditto.
(delete_fork_command): Replace mention of fork/checkpoint by
checkpoint only.
(detach_fork_command): Likewise. Don't delete the checkpoint from
the inferior list.
(info_forks_command): Adjust.
(restore_detach_fork): Delete.
(checkpointing_pid): New.
(linux_fork_checkpointing_p): New.
(save_detach_fork): Delete.
(checkpoint_command): Delete temp_detach_fork. Don't remove
breakpoints, that's a nop. Store the pid of the process we're
checkpointing, and use make_cleanup_restore_integer to restore it.
Don't reinsert breakpoints here.
(process_command, fork_command): Delete.
(restart_command): Update comments to only mention checkpoints,
not forks.
(_initialize_linux_fork): Delete "fork", "process", "info forks"
commands.

* NEWS: Mention multi-inferior debugging. Mention 'info
inferiors', 'inferior', 'detach inferior' and 'kill inferior' as
new commands.

'fork', 'process', 'delete fork' and 'detach fork' are now gone.
gdb/testsuite/

* gdb.base/multi-forks.exp: Only run detach-on-fork tests on
linux. Adjust to use "inferior", "info inferiors", "detach
inferior" and "kill inferior" instead of "restart", "info fork",
"detach fork" and "delete fork".
* gdb.base/ending-run.exp: Spell out "info".
* gdb.base/help.exp: Adjust to use test_prefix_command_help for
the "kill" command.

2009-07-02 Pedro Alves <pedro@codesourcery.com>
* gdb.texinfo (Debugging multiple inferiors): Document the
"inferior", "detach inferior" and "kill inferior" commands.
(Debugging Programs with Multiple Processes): Adjust to mention
generic "inferior" commands. Delete mention of "detach fork" and

events in lp->status or lp->waitstatus (see stop_wait_callback),
|
|
|
|
|
and GDB core hasn't seen any signal for those threads.
|
|
|
|
|
Otherwise, the last signal reported to the core is found in the

thread object's stop_signal.

There's a corner case that isn't handled here at present. Only
|
|
|
|
|
if the thread stopped with a TARGET_WAITKIND_STOPPED does
|
|
|
|
|
stop_signal make sense as a real signal to pass to the inferior.
|
|
|
|
|
Some catchpoint related events, like
|
|
|
|
|
TARGET_WAITKIND_(V)FORK|EXEC|SYSCALL, have their stop_signal set
|
|
|
|
|
to TARGET_SIGNAL_SIGTRAP when the catchpoint triggers. But,
|
|
|
|
|
those traps are debug API (ptrace in our case) related and
|
|
|
|
|
induced; the inferior wouldn't see them if it wasn't being
|
|
|
|
|
traced. Hence, we should never pass them to the inferior, even
|
|
|
|
|
when set to pass state. Since this corner case isn't handled by
|
|
|
|
|
infrun.c when proceeding with a signal, for consistency, neither
|
|
|
|
|
do we handle it here (or elsewhere in the file we check for
|
|
|
|
|
signal pass state). Normally SIGTRAP isn't set to pass state, so
|
|
|
|
|
this is really a corner case. */

PT_STEP still resumes executing the syscall and reports a

- Only PT_SYSCALL catches syscall enters. If we last

|
|

syscall enter. If we last single-stepped this thread, this

|
|
has to be a syscall exit.
|
|
|
|

2009-07-02 Pedro Alves <pedro@codesourcery.com>
* linux-nat.c (linux_child_follow_fork): If we're staying attached
to the child process, enable event reporting on it. Don't handle
checkpoints here. Instead, add the child fork to the lwp thread
and inferior lists without clobbering the previous inferior. Let
the thread_db layer learn about a new child process, even if
following the parent.
(linux_nat_switch_fork): Delete lwps of the current inferior only,
instead of clearing the whole list. Use thread_change_ptid to
give the core the illusion the new checkpoint is still the same
inferior. Clear the register cache.
(linux_handle_extended_wait): Handle checkpoints here.
(linux_multi_process): Turn on.
* linux-fork.c (struct fork_info) <pc>: Remove field.
(init_fork_list): Do not delete the checkpoint from the inferior
list (it is not there).
(fork_load_infrun_state): Don't switch inferior_ptid here. Pass
the new checkpoint's ptid to linux_nat_switch_fork.
(fork_save_infrun_state): Make static. Don't stop the pc field of
fork_info, it's gone.
(linux_fork_mourn_inferior): Don't delete the checkpoint from the
inferior list, it's not there.
(linux_fork_detach): Ditto.
(delete_fork_command): Replace mention of fork/checkpoint by
checkpoint only.
(detach_fork_command): Likewise. Don't delete the checkpoint from
the inferior list.
(info_forks_command): Adjust.
(restore_detach_fork): Delete.
(checkpointing_pid): New.
(linux_fork_checkpointing_p): New.
(save_detach_fork): Delete.
(checkpoint_command): Delete temp_detach_fork. Don't remove
breakpoints, that's a nop. Store the pid of the process we're
checkpointing, and use make_cleanup_restore_integer to restore it.
Don't reinsert breakpoints here.
(process_command, fork_command): Delete.
(restart_command): Update comments to only mention checkpoints,
not forks.
(_initialize_linux_fork): Delete "fork", "process", "info forks"
commands.
* linux-fork.h (fork_save_infrun_state, fork_list): Delete
declarations.
(linux_fork_checkpointing_p): Declare.
* cli/cli-cmds.c (killlist): New.
* cli/cli-cmds.h (killlist): Declare.
* gdbcmd.h (killlist): Declare.
* inferior.c: Include "gdbthread.h".
(detach_inferior_command, kill_inferior_command)
(inferior_command): New.
(info_inferiors_command): Allow specifying a specific inferior id.
(_initialize_inferiors): Register "inferior", "kill inferior" and
"detach inferior" commands.
* infcmd.c (_initialize_infcmd): Make "kill" a prefix command.
* gdbthread.h (any_thread_of_process): Declare.
* thread.c (any_thread_of_process): New.
* NEWS: Mention multi-inferior debugging. Mention 'info
inferiors', 'inferior', 'detach inferior' and 'kill inferior' as
new commands.
(Removed commands): New section, mentioning that 'info forks',
'fork', 'process', 'delete fork' and 'detach fork' are now gone.
gdb/testsuite/
2009-07-02 Pedro Alves <pedro@codesourcery.com>
* gdb.base/multi-forks.exp: Only run detach-on-fork tests on
linux. Adjust to use "inferior", "info inferiors", "detach
inferior" and "kill inferior" instead of "restart", "info fork",
"detach fork" and "delete fork".
* gdb.base/ending-run.exp: Spell out "info".
* gdb.base/help.exp: Adjust to use test_prefix_command_help for
the "kill" command.
gdb/doc/
2009-07-02 Pedro Alves <pedro@codesourcery.com>
* gdb.texinfo (Debugging multiple inferiors): Document the
"inferior", "detach inferior" and "kill inferior" commands.
(Debugging Programs with Multiple Processes): Adjust to mention
generic "inferior" commands. Delete mention of "detach fork" and
"delete fork". Cross reference to "Debugging multiple inferiors"
section.

|
|
|
|
|
|
|
|
On some archs, like x86, that use debug registers to set
|
|
|
|
|
watchpoints, it's possible that the way to know which watched
|
|
|
|
|
address trapped, is to check the register that is used to select
|
|
|
|
|
which address to watch. Problem is, between setting the watchpoint
|
|
|
|
|
and reading back which data address trapped, the user may change
|
|
|
|
|
the set of watchpoints, and, as a consequence, GDB changes the
|
|
|
|
|
debug registers in the inferior. To avoid reading back a stale
|
|
|
|
|
stopped-data-address when that happens, we cache in LP the fact
|
|
|
|
|
that a watchpoint trapped, and the corresponding data address, as
|
|
|
|
|
soon as we see LP stop with a SIGTRAP. If GDB changes the debug
|
|
|
|

registers meanwhile, we have the cached data we can rely on. */

then just arrange for it to hit it again later. We don't keep
|
|
|
|
|
the SIGTRAP status and don't forward the SIGTRAP signal to the
|
|
|
|
|
LWP. We will handle the current event, eventually we will resume
|
|
|
|
|
all LWPs, and this one will get its breakpoint trap again.
|
|
|
|
|

If we do not do this, then we run the risk that the user will
|
|
|

|
delete or disable the breakpoint, but the LWP will have already
|
|
|
|
|
tripped on it. */
