auto-generate most target debug methods The target debug methods are inconsistently maintained. Most to_* methods have some kind of targetdebug awareness, but not all of them do. The ones that do vary in the quantity and quality of output they generate. This patch changes most of the target debug methods to be automatically generated. All the arguments are printed, and separate lines are printed for entering and existing the outermost call to the target stack. For example now you'd see: -> multi-thread->to_terminal_ours (...) -> multi-thread->to_is_async_p (...) <- multi-thread->to_is_async_p (0x1ebb580) = 1 <- multi-thread->to_terminal_ours (0x1ebb580) -> multi-thread->to_thread_address_space (...) <- multi-thread->to_thread_address_space (0x1ebb580, 26802) = 1 In this case you can see nested calls. The "multi-thread" on the left hand side is the topmost target's shortname. There are some oddities with this patch. I'm on the fence about it all, I really just wrote it on a whim. It's not simple to convert every possible method, since a few don't participate in target delegation. Printing is done by type, so I introduced some new debug-printing-specific typedefs to handle cases where it is nicer to do something else. On the plus side, this lays the groundwork for making targetdebug affect every layer of the target stack. The idea would be to wrap each target_ops in the stack with its own debug_target, and then you could see calls propagate down the stack and back up; I suppose with indentation to make it prettier. (That said there are some gotchas lurking in this idea due to target stack introspection.)

add target method delegation This patch replaces some code in the record targets with target method delegation. record-full.c stores pointers to many target methods when the record target is pushed. Then it later delegates some calls via these. This is wrong because it violates the target stack contract. In particular it is ok to unpush a target at any stratum, but record-full does not keep track of this, so it could potentially call into an unpushed target. This patch fixes the problem by using the newly-introduced generic approach to target delegation for the methods in question. 2014-02-19 Tom Tromey <tromey@redhat.com> * record-full.c (record_full_beneath_to_resume_ops) (record_full_beneath_to_resume, record_full_beneath_to_wait_ops) (record_full_beneath_to_wait) (record_full_beneath_to_store_registers_ops) (record_full_beneath_to_store_registers) (record_full_beneath_to_xfer_partial_ops) (record_full_beneath_to_xfer_partial) (record_full_beneath_to_insert_breakpoint_ops) (record_full_beneath_to_insert_breakpoint) (record_full_beneath_to_remove_breakpoint_ops) (record_full_beneath_to_remove_breakpoint) (record_full_beneath_to_stopped_by_watchpoint) (record_full_beneath_to_stopped_data_address) (record_full_beneath_to_async, tmp_to_resume_ops, tmp_to_resume) (tmp_to_wait_ops, tmp_to_wait, tmp_to_store_registers_ops) (tmp_to_store_registers, tmp_to_xfer_partial_ops) (tmp_to_xfer_partial, tmp_to_instmp_to_insert_breakpoint_ops) (tmp_to_insert_breakpoint, tmp_to_remove_breakpoint_ops) (tmp_to_remove_breakpoint, tmp_to_stopped_by_watchpoint) (tmp_to_stopped_data_address, tmp_to_async): Remove.

auto-generate most target debug methods The target debug methods are inconsistently maintained. Most to_* methods have some kind of targetdebug awareness, but not all of them do. The ones that do vary in the quantity and quality of output they generate. This patch changes most of the target debug methods to be automatically generated. All the arguments are printed, and separate lines are printed for entering and existing the outermost call to the target stack. For example now you'd see: -> multi-thread->to_terminal_ours (...) -> multi-thread->to_is_async_p (...) <- multi-thread->to_is_async_p (0x1ebb580) = 1 <- multi-thread->to_terminal_ours (0x1ebb580) -> multi-thread->to_thread_address_space (...) <- multi-thread->to_thread_address_space (0x1ebb580, 26802) = 1 In this case you can see nested calls. The "multi-thread" on the left hand side is the topmost target's shortname. There are some oddities with this patch. I'm on the fence about it all, I really just wrote it on a whim. It's not simple to convert every possible method, since a few don't participate in target delegation. Printing is done by type, so I introduced some new debug-printing-specific typedefs to handle cases where it is nicer to do something else. On the plus side, this lays the groundwork for making targetdebug affect every layer of the target stack. The idea would be to wrap each target_ops in the stack with its own debug_target, and then you could see calls propagate down the stack and back up; I suppose with indentation to make it prettier. (That said there are some gotchas lurking in this idea due to target stack introspection.)

add target method delegation This patch replaces some code in the record targets with target method delegation. record-full.c stores pointers to many target methods when the record target is pushed. Then it later delegates some calls via these. This is wrong because it violates the target stack contract. In particular it is ok to unpush a target at any stratum, but record-full does not keep track of this, so it could potentially call into an unpushed target. This patch fixes the problem by using the newly-introduced generic approach to target delegation for the methods in question. 2014-02-19 Tom Tromey <tromey@redhat.com> * record-full.c (record_full_beneath_to_resume_ops) (record_full_beneath_to_resume, record_full_beneath_to_wait_ops) (record_full_beneath_to_wait) (record_full_beneath_to_store_registers_ops) (record_full_beneath_to_store_registers) (record_full_beneath_to_xfer_partial_ops) (record_full_beneath_to_xfer_partial) (record_full_beneath_to_insert_breakpoint_ops) (record_full_beneath_to_insert_breakpoint) (record_full_beneath_to_remove_breakpoint_ops) (record_full_beneath_to_remove_breakpoint) (record_full_beneath_to_stopped_by_watchpoint) (record_full_beneath_to_stopped_data_address) (record_full_beneath_to_async, tmp_to_resume_ops, tmp_to_resume) (tmp_to_wait_ops, tmp_to_wait, tmp_to_store_registers_ops) (tmp_to_store_registers, tmp_to_xfer_partial_ops) (tmp_to_xfer_partial, tmp_to_instmp_to_insert_breakpoint_ops) (tmp_to_insert_breakpoint, tmp_to_remove_breakpoint_ops) (tmp_to_remove_breakpoint, tmp_to_stopped_by_watchpoint) (tmp_to_stopped_data_address, tmp_to_async): Remove.

add target method delegation This patch replaces some code in the record targets with target method delegation. record-full.c stores pointers to many target methods when the record target is pushed. Then it later delegates some calls via these. This is wrong because it violates the target stack contract. In particular it is ok to unpush a target at any stratum, but record-full does not keep track of this, so it could potentially call into an unpushed target. This patch fixes the problem by using the newly-introduced generic approach to target delegation for the methods in question. 2014-02-19 Tom Tromey <tromey@redhat.com> * record-full.c (record_full_beneath_to_resume_ops) (record_full_beneath_to_resume, record_full_beneath_to_wait_ops) (record_full_beneath_to_wait) (record_full_beneath_to_store_registers_ops) (record_full_beneath_to_store_registers) (record_full_beneath_to_xfer_partial_ops) (record_full_beneath_to_xfer_partial) (record_full_beneath_to_insert_breakpoint_ops) (record_full_beneath_to_insert_breakpoint) (record_full_beneath_to_remove_breakpoint_ops) (record_full_beneath_to_remove_breakpoint) (record_full_beneath_to_stopped_by_watchpoint) (record_full_beneath_to_stopped_data_address) (record_full_beneath_to_async, tmp_to_resume_ops, tmp_to_resume) (tmp_to_wait_ops, tmp_to_wait, tmp_to_store_registers_ops) (tmp_to_store_registers, tmp_to_xfer_partial_ops) (tmp_to_xfer_partial, tmp_to_instmp_to_insert_breakpoint_ops) (tmp_to_insert_breakpoint, tmp_to_remove_breakpoint_ops) (tmp_to_remove_breakpoint, tmp_to_stopped_by_watchpoint) (tmp_to_stopped_data_address, tmp_to_async): Remove.

auto-generate most target debug methods The target debug methods are inconsistently maintained. Most to_* methods have some kind of targetdebug awareness, but not all of them do. The ones that do vary in the quantity and quality of output they generate. This patch changes most of the target debug methods to be automatically generated. All the arguments are printed, and separate lines are printed for entering and existing the outermost call to the target stack. For example now you'd see: -> multi-thread->to_terminal_ours (...) -> multi-thread->to_is_async_p (...) <- multi-thread->to_is_async_p (0x1ebb580) = 1 <- multi-thread->to_terminal_ours (0x1ebb580) -> multi-thread->to_thread_address_space (...) <- multi-thread->to_thread_address_space (0x1ebb580, 26802) = 1 In this case you can see nested calls. The "multi-thread" on the left hand side is the topmost target's shortname. There are some oddities with this patch. I'm on the fence about it all, I really just wrote it on a whim. It's not simple to convert every possible method, since a few don't participate in target delegation. Printing is done by type, so I introduced some new debug-printing-specific typedefs to handle cases where it is nicer to do something else. On the plus side, this lays the groundwork for making targetdebug affect every layer of the target stack. The idea would be to wrap each target_ops in the stack with its own debug_target, and then you could see calls propagate down the stack and back up; I suppose with indentation to make it prettier.

The ones that do vary in the quantity and quality of output they generate. This patch changes most of the target debug methods to be automatically generated. All the arguments are printed, and separate lines are printed for entering and existing the outermost call to the target stack. For example now you'd see: -> multi-thread->to_terminal_ours (...) -> multi-thread->to_is_async_p (...) <- multi-thread->to_is_async_p (0x1ebb580) = 1 <- multi-thread->to_terminal_ours (0x1ebb580) -> multi-thread->to_thread_address_space (...) <- multi-thread->to_thread_address_space (0x1ebb580, 26802) = 1 In this case you can see nested calls. The "multi-thread" on the left hand side is the topmost target's shortname. There are some oddities with this patch. I'm on the fence about it all, I really just wrote it on a whim. It's not simple to convert every possible method, since a few don't participate in target delegation. Printing is done by type, so I introduced some new debug-printing-specific typedefs to handle cases where it is nicer to do something else.

auto-generate most target debug methods The target debug methods are inconsistently maintained. Most to_* methods have some kind of targetdebug awareness, but not all of them do. The ones that do vary in the quantity and quality of output they generate. This patch changes most of the target debug methods to be automatically generated. All the arguments are printed, and separate lines are printed for entering and existing the outermost call to the target stack. For example now you'd see: -> multi-thread->to_terminal_ours (...) -> multi-thread->to_is_async_p (...) <- multi-thread->to_is_async_p (0x1ebb580) = 1 <- multi-thread->to_terminal_ours (0x1ebb580) -> multi-thread->to_thread_address_space (...) <- multi-thread->to_thread_address_space (0x1ebb580, 26802) = 1 In this case you can see nested calls. The "multi-thread" on the left hand side is the topmost target's shortname. There are some oddities with this patch. I'm on the fence about it all, I really just wrote it on a whim. It's not simple to convert every possible method, since a few don't participate in target delegation. Printing is done by type, so I introduced some new debug-printing-specific typedefs to handle cases where it is nicer to do something else. On the plus side, this lays the groundwork for making targetdebug affect every layer of the target stack. The idea would be to wrap each target_ops in the stack with its own debug_target, and then you could see calls propagate down the stack and back up; I suppose with indentation to make it prettier. (That said there are some gotchas lurking in this idea due to target stack introspection.)

add target method delegation This patch replaces some code in the record targets with target method delegation. record-full.c stores pointers to many target methods when the record target is pushed. Then it later delegates some calls via these. This is wrong because it violates the target stack contract. In particular it is ok to unpush a target at any stratum, but record-full does not keep track of this, so it could potentially call into an unpushed target. This patch fixes the problem by using the newly-introduced generic approach to target delegation for the methods in question. 2014-02-19 Tom Tromey <tromey@redhat.com> * record-full.c (record_full_beneath_to_resume_ops) (record_full_beneath_to_resume, record_full_beneath_to_wait_ops) (record_full_beneath_to_wait) (record_full_beneath_to_store_registers_ops) (record_full_beneath_to_store_registers) (record_full_beneath_to_xfer_partial_ops) (record_full_beneath_to_xfer_partial) (record_full_beneath_to_insert_breakpoint_ops) (record_full_beneath_to_insert_breakpoint) (record_full_beneath_to_remove_breakpoint_ops) (record_full_beneath_to_remove_breakpoint) (record_full_beneath_to_stopped_by_watchpoint) (record_full_beneath_to_stopped_data_address) (record_full_beneath_to_async, tmp_to_resume_ops, tmp_to_resume) (tmp_to_wait_ops, tmp_to_wait, tmp_to_store_registers_ops) (tmp_to_store_registers, tmp_to_xfer_partial_ops) (tmp_to_xfer_partial, tmp_to_instmp_to_insert_breakpoint_ops) (tmp_to_insert_breakpoint, tmp_to_remove_breakpoint_ops) (tmp_to_remove_breakpoint, tmp_to_stopped_by_watchpoint) (tmp_to_stopped_data_address, tmp_to_async): Remove.

auto-generate most target debug methods The target debug methods are inconsistently maintained. Most to_* methods have some kind of targetdebug awareness, but not all of them do.

auto-generate most target debug methods The target debug methods are inconsistently maintained. Most to_* methods have some kind of targetdebug awareness, but not all of them do. The ones that do vary in the quantity and quality of output they generate. This patch changes most of the target debug methods to be automatically generated. All the arguments are printed, and separate lines are printed for entering and existing the outermost call to the target stack. For example now you'd see: -> multi-thread->to_terminal_ours (...) -> multi-thread->to_is_async_p (...) <- multi-thread->to_is_async_p (0x1ebb580) = 1 <- multi-thread->to_terminal_ours (0x1ebb580) -> multi-thread->to_thread_address_space (...) <- multi-thread->to_thread_address_space (0x1ebb580, 26802) = 1 In this case you can see nested calls. The "multi-thread" on the left hand side is the topmost target's shortname. There are some oddities with this patch. I'm on the fence about it all, I really just wrote it on a whim. It's not simple to convert every possible method, since a few don't participate in target delegation. Printing is done by type, so I introduced some new debug-printing-specific typedefs to handle cases where it is nicer to do something else. On the plus side, this lays the groundwork for making targetdebug affect every layer of the target stack. The idea would be to wrap each target_ops in the stack with its own debug_target, and then you could see calls propagate down the stack and back up; I suppose with indentation to make it prettier.

auto-generate most target debug methods The target debug methods are inconsistently maintained. Most to_* methods have some kind of targetdebug awareness, but not all of them do. The ones that do vary in the quantity and quality of output they generate. This patch changes most of the target debug methods to be automatically generated. All the arguments are printed, and separate lines are printed for entering and existing the outermost call to the target stack. For example now you'd see: -> multi-thread->to_terminal_ours (...) -> multi-thread->to_is_async_p (...) <- multi-thread->to_is_async_p (0x1ebb580) = 1 <- multi-thread->to_terminal_ours (0x1ebb580) -> multi-thread->to_thread_address_space (...) <- multi-thread->to_thread_address_space (0x1ebb580, 26802) = 1 In this case you can see nested calls. The "multi-thread" on the left hand side is the topmost target's shortname. There are some oddities with this patch. I'm on the fence about it all, I really just wrote it on a whim. It's not simple to convert every possible method, since a few don't participate in target delegation. Printing is done by type, so I introduced some new debug-printing-specific typedefs to handle cases where it is nicer to do something else. On the plus side, this lays the groundwork for making targetdebug affect every layer of the target stack. The idea would be to wrap each target_ops in the stack with its own debug_target, and then you could see calls propagate down the stack and back up; I suppose with indentation to make it prettier.

auto-generate most target debug methods The target debug methods are inconsistently maintained. Most to_* methods have some kind of targetdebug awareness, but not all of them do. The ones that do vary in the quantity and quality of output they generate. This patch changes most of the target debug methods to be automatically generated. All the arguments are printed, and separate lines are printed for entering and existing the outermost call to the target stack. For example now you'd see: -> multi-thread->to_terminal_ours (...) -> multi-thread->to_is_async_p (...) <- multi-thread->to_is_async_p (0x1ebb580) = 1 <- multi-thread->to_terminal_ours (0x1ebb580) -> multi-thread->to_thread_address_space (...) <- multi-thread->to_thread_address_space (0x1ebb580, 26802) = 1 In this case you can see nested calls. The "multi-thread" on the left hand side is the topmost target's shortname. There are some oddities with this patch. I'm on the fence about it all, I really just wrote it on a whim. It's not simple to convert every possible method, since a few don't participate in target delegation. Printing is done by type, so I introduced some new debug-printing-specific typedefs to handle cases where it is nicer to do something else. On the plus side, this lays the groundwork for making targetdebug affect every layer of the target stack. The idea would be to wrap each target_ops in the stack with its own debug_target, and then you could see calls propagate down the stack and back up; I suppose with indentation to make it prettier.

auto-generate most target debug methods The target debug methods are inconsistently maintained. Most to_* methods have some kind of targetdebug awareness, but not all of them do. The ones that do vary in the quantity and quality of output they generate. This patch changes most of the target debug methods to be automatically generated. All the arguments are printed, and separate lines are printed for entering and existing the outermost call to the target stack. For example now you'd see: -> multi-thread->to_terminal_ours (...) -> multi-thread->to_is_async_p (...) <- multi-thread->to_is_async_p (0x1ebb580) = 1 <- multi-thread->to_terminal_ours (0x1ebb580) -> multi-thread->to_thread_address_space (...) <- multi-thread->to_thread_address_space (0x1ebb580, 26802) = 1 In this case you can see nested calls. The "multi-thread" on the left hand side is the topmost target's shortname. There are some oddities with this patch. I'm on the fence about it all, I really just wrote it on a whim. It's not simple to convert every possible method, since a few don't participate in target delegation. Printing is done by type, so I introduced some new debug-printing-specific typedefs to handle cases where it is nicer to do something else. On the plus side, this lays the groundwork for making targetdebug affect every layer of the target stack. The idea would be to wrap each target_ops in the stack with its own debug_target, and then you could see calls propagate down the stack and back up; I suppose with indentation to make it prettier. (That said there are some gotchas lurking in this idea due to target stack introspection.)

Push pruning old threads down to the target When GDB wants to sync the thread list with the target's (e.g., due to "info threads"), it calls update_thread_list: update_thread_list (void) { prune_threads (); target_find_new_threads (); update_threads_executing (); } And then prune_threads does: prune_threads (void) { struct thread_info *tp, *next; for (tp = thread_list; tp; tp = next) { next = tp->next; if (!thread_alive (tp)) delete_thread (tp->ptid); } } Calling thread_live on each thread one by one is expensive. E.g., on Linux, it ends up doing kill(SIG0) once for each thread. Not a big deal, but still a bunch of syscalls... With the remote target, it's cumbersome. That thread_alive call ends up generating one T packet per thread: Sending packet: $Tp2141.2150#82...Packet received: OK Sending packet: $Tp2141.214f#b7...Packet received: OK Sending packet: $Tp2141.2141#82...Packet received: OK Sending packet: $qXfer:threads:read::0,fff#03...Packet received: l<threads>\n<thread id="p2141.2141" core="2"/>\n<thread id="p2141.214f" core="1"/>\n<thread id="p2141.2150" core="2"/>\n</threads>\n That seems a bit silly when target_find_new_threads method implementations will always fetch the whole current set of target threads, and then add those that are not in GDB's thread list, to GDB's thread list. This patch thus pushes down the responsibility of pruning dead threads to the target_find_new_threads method instead, so a target may implement pruning dead threads however it wants. Once we do that, target_find_new_threads becomes a misnomer, so the patch renames it to target_update_thread_list. The patch doesn't attempt to do any optimization to any target yet.

auto-generate most target debug methods The target debug methods are inconsistently maintained. Most to_* methods have some kind of targetdebug awareness, but not all of them do. The ones that do vary in the quantity and quality of output they generate. This patch changes most of the target debug methods to be automatically generated. All the arguments are printed, and separate lines are printed for entering and existing the outermost call to the target stack. For example now you'd see: -> multi-thread->to_terminal_ours (...) -> multi-thread->to_is_async_p (...) <- multi-thread->to_is_async_p (0x1ebb580) = 1 <- multi-thread->to_terminal_ours (0x1ebb580) -> multi-thread->to_thread_address_space (...) <- multi-thread->to_thread_address_space (0x1ebb580, 26802) = 1 In this case you can see nested calls. The "multi-thread" on the left hand side is the topmost target's shortname. There are some oddities with this patch. I'm on the fence about it all, I really just wrote it on a whim. It's not simple to convert every possible method, since a few don't participate in target delegation.

static void
Push pruning old threads down to the target When GDB wants to sync the thread list with the target's (e.g., due to "info threads"), it calls update_thread_list: update_thread_list (void) { prune_threads (); target_find_new_threads (); update_threads_executing (); } And then prune_threads does: prune_threads (void) { struct thread_info *tp, *next; for (tp = thread_list; tp; tp = next) { next = tp->next; if (!thread_alive (tp)) delete_thread (tp->ptid); } } Calling thread_live on each thread one by one is expensive. E.g., on Linux, it ends up doing kill(SIG0) once for each thread. Not a big deal, but still a bunch of syscalls... With the remote target, it's cumbersome. That thread_alive call ends up generating one T packet per thread: Sending packet: $Tp2141.2150#82...Packet received: OK Sending packet: $Tp2141.214f#b7...Packet received: OK Sending packet: $Tp2141.2141#82...Packet received: OK Sending packet: $qXfer:threads:read::0,fff#03...Packet received: l<threads>\n<thread id="p2141.2141" core="2"/>\n<thread id="p2141.214f" core="1"/>\n<thread id="p2141.2150" core="2"/>\n</threads>\n That seems a bit silly when target_find_new_threads method implementations will always fetch the whole current set of target threads, and then add those that are not in GDB's thread list, to GDB's thread list. This patch thus pushes down the responsibility of pruning dead threads to the target_find_new_threads method instead, so a target may implement pruning dead threads however it wants. Once we do that, target_find_new_threads becomes a misnomer, so the patch renames it to target_update_thread_list. The patch doesn't attempt to do any optimization to any target yet. It simply exports prune_threads, and makes all implementations of target_update_thread_list call that.

debug_update_thread_list (struct target_ops *self)
auto-generate most target debug methods The target debug methods are inconsistently maintained. Most to_* methods have some kind of targetdebug awareness, but not all of them do. The ones that do vary in the quantity and quality of output they generate. This patch changes most of the target debug methods to be automatically generated. All the arguments are printed, and separate lines are printed for entering and existing the outermost call to the target stack. For example now you'd see: -> multi-thread->to_terminal_ours (...) -> multi-thread->to_is_async_p (...) <- multi-thread->to_is_async_p (0x1ebb580) = 1 <- multi-thread->to_terminal_ours (0x1ebb580) -> multi-thread->to_thread_address_space (...) <- multi-thread->to_thread_address_space (0x1ebb580, 26802) = 1 In this case you can see nested calls. The "multi-thread" on the left hand side is the topmost target's shortname. There are some oddities with this patch. I'm on the fence about it all, I really just wrote it on a whim. It's not simple to convert every possible method, since a few don't participate in target delegation. Printing is done by type, so I introduced some new debug-printing-specific typedefs to handle cases where it is nicer to do something else. On the plus side, this lays the groundwork for making targetdebug affect every layer of the target stack.

auto-generate most target debug methods The target debug methods are inconsistently maintained. Most to_* methods have some kind of targetdebug awareness, but not all of them do. The ones that do vary in the quantity and quality of output they generate. This patch changes most of the target debug methods to be automatically generated. All the arguments are printed, and separate lines are printed for entering and existing the outermost call to the target stack. For example now you'd see: -> multi-thread->to_terminal_ours (...) -> multi-thread->to_is_async_p (...) <- multi-thread->to_is_async_p (0x1ebb580) = 1 <- multi-thread->to_terminal_ours (0x1ebb580) -> multi-thread->to_thread_address_space (...) <- multi-thread->to_thread_address_space (0x1ebb580, 26802) = 1 In this case you can see nested calls. The "multi-thread" on the left hand side is the topmost target's shortname. There are some oddities with this patch. I'm on the fence about it all, I really just wrote it on a whim. It's not simple to convert every possible method, since a few don't participate in target delegation. Printing is done by type, so I introduced some new debug-printing-specific typedefs to handle cases where it is nicer to do something else. On the plus side, this lays the groundwork for making targetdebug affect every layer of the target stack. The idea would be to wrap each target_ops in the stack with its own debug_target, and then you could see calls propagate down the stack and back up; I suppose with indentation to make it prettier.

auto-generate most target debug methods The target debug methods are inconsistently maintained. Most to_* methods have some kind of targetdebug awareness, but not all of them do. The ones that do vary in the quantity and quality of output they generate. This patch changes most of the target debug methods to be automatically generated. All the arguments are printed, and separate lines are printed for entering and existing the outermost call to the target stack. For example now you'd see: -> multi-thread->to_terminal_ours (...) -> multi-thread->to_is_async_p (...) <- multi-thread->to_is_async_p (0x1ebb580) = 1 <- multi-thread->to_terminal_ours (0x1ebb580) -> multi-thread->to_thread_address_space (...) <- multi-thread->to_thread_address_space (0x1ebb580, 26802) = 1 In this case you can see nested calls. The "multi-thread" on the left hand side is the topmost target's shortname. There are some oddities with this patch. I'm on the fence about it all, I really just wrote it on a whim. It's not simple to convert every possible method, since a few don't participate in target delegation. Printing is done by type, so I introduced some new debug-printing-specific typedefs to handle cases where it is nicer to do something else. On the plus side, this lays the groundwork for making targetdebug affect every layer of the target stack. The idea would be to wrap each target_ops in the stack with its own debug_target, and then you could see calls propagate down the stack and back up; I suppose with indentation to make it prettier. (That said there are some gotchas lurking in this idea due to target stack introspection.)

add target method delegation This patch replaces some code in the record targets with target method delegation. record-full.c stores pointers to many target methods when the record target is pushed. Then it later delegates some calls via these. This is wrong because it violates the target stack contract. In particular it is ok to unpush a target at any stratum, but record-full does not keep track of this, so it could potentially call into an unpushed target. This patch fixes the problem by using the newly-introduced generic approach to target delegation for the methods in question. 2014-02-19 Tom Tromey <tromey@redhat.com> * record-full.c (record_full_beneath_to_resume_ops) (record_full_beneath_to_resume, record_full_beneath_to_wait_ops) (record_full_beneath_to_wait) (record_full_beneath_to_store_registers_ops) (record_full_beneath_to_store_registers) (record_full_beneath_to_xfer_partial_ops) (record_full_beneath_to_xfer_partial) (record_full_beneath_to_insert_breakpoint_ops) (record_full_beneath_to_insert_breakpoint) (record_full_beneath_to_remove_breakpoint_ops) (record_full_beneath_to_remove_breakpoint) (record_full_beneath_to_stopped_by_watchpoint) (record_full_beneath_to_stopped_data_address) (record_full_beneath_to_async, tmp_to_resume_ops, tmp_to_resume) (tmp_to_wait_ops, tmp_to_wait, tmp_to_store_registers_ops) (tmp_to_store_registers, tmp_to_xfer_partial_ops) (tmp_to_xfer_partial, tmp_to_instmp_to_insert_breakpoint_ops) (tmp_to_insert_breakpoint, tmp_to_remove_breakpoint_ops) (tmp_to_remove_breakpoint, tmp_to_stopped_by_watchpoint) (tmp_to_stopped_data_address, tmp_to_async): Remove.

fix regressions with target-async A patch in the target cleanup series caused a regression when using record with target-async. Version 4 of the patch is here: https://sourceware.org/ml/gdb-patches/2014-03/msg00159.html The immediate problem is that record supplies to_can_async_p and to_is_async_p methods, but does not supply a to_async method. So, when target-async is set, record claims to support async -- but if the underlying target does not support async, then the to_async method call will end up in that method's default implementation, namely tcomplain. This worked previously because the record target used to provide a to_async method; one that (erroneously, only at push time) checked the other members of the target stack, and then simply dropped to_async calls in the "does not implement async" case. My first thought was to simply drop tcomplain as the default for to_async. This works, but Pedro pointed out that the only reason record has to supply to_can_async_p and to_is_async_p is that these default to using the find_default_run_target machinery -- and these defaults are only needed by "run" and "attach". So, a nicer solution presents itself: change run and attach to explicitly call into the default run target when needed; and change to_is_async_p and to_can_async_p to default to "return 0". This makes the target stack simpler to use and lets us remove the method implementations from record. This is also in harmony with other plans for the target stack; namely trying to reduce the impact of find_default_run_target. This approach makes it clear that find_default_is_async_p is not needed -- it is asking whether a target that may not even be pushed is actually async, which seems like a nonsensical question. While an improvement, this approach proved to introduce the same bug when using the core target. Looking a bit deeper, the issue is that code in "attach" and "run" may need to use either the current target stack or the default run target -- but different calls into the target API in those functions could wind up querying different targets. This new patch makes the target to use more explicit in "run" and "attach". Then these commands explicitly make the needed calls against that target. This ensures that a single target is used for all relevant operations. This lets us remove a couple find_default_* functions from various targets, including the dummy target. I think this is a decent understandability improvement. One issue I see with this patch is that the new calls in "run" and "attach" are not very much like the rest of the target API. I think fundamentally this is due to bad factoring in the target API, which may need to be fixed for multi-target. Tackling that seemed ambitious for a regression fix. While working on this I noticed that there don't seem to be any test cases that involve both target-async and record, so this patch changes break-precsave.exp to add some. It also changes corefile.exp to add some target-async tests; these pass with current trunk and with this patch applied, but fail with the v1 patch. This patch differs from v4 in that it moves initialization of to_can_async_p and to_supports_non_stop into inf-child, adds some assertions to complete_target_initialization, and adds some comments to target.h.

It also changes corefile.exp to add some target-async tests; these pass with current trunk and with this patch applied, but fail with the v1 patch. This patch differs from v4 in that it moves initialization of to_can_async_p and to_supports_non_stop into inf-child, adds some assertions to complete_target_initialization, and adds some comments to target.h.

auto-generate most target debug methods The target debug methods are inconsistently maintained. Most to_* methods have some kind of targetdebug awareness, but not all of them do. The ones that do vary in the quantity and quality of output they generate. This patch changes most of the target debug methods to be automatically generated. All the arguments are printed, and separate lines are printed for entering and existing the outermost call to the target stack. For example now you'd see: -> multi-thread->to_terminal_ours (...) -> multi-thread->to_is_async_p (...) <- multi-thread->to_is_async_p (0x1ebb580) = 1 <- multi-thread->to_terminal_ours (0x1ebb580) -> multi-thread->to_thread_address_space (...) <- multi-thread->to_thread_address_space (0x1ebb580, 26802) = 1 In this case you can see nested calls. The "multi-thread" on the left hand side is the topmost target's shortname. There are some oddities with this patch. I'm on the fence about it all, I really just wrote it on a whim. It's not simple to convert every possible method, since a few don't participate in target delegation. Printing is done by type, so I introduced some new debug-printing-specific typedefs to handle cases where it is nicer to do something else. On the plus side, this lays the groundwork for making targetdebug affect every layer of the target stack. The idea would be to wrap each target_ops in the stack with its own debug_target, and then you could see calls propagate down the stack and back up; I suppose with indentation to make it prettier.

add target method delegation This patch replaces some code in the record targets with target method delegation. record-full.c stores pointers to many target methods when the record target is pushed. Then it later delegates some calls via these. This is wrong because it violates the target stack contract. In particular it is ok to unpush a target at any stratum, but record-full does not keep track of this, so it could potentially call into an unpushed target. This patch fixes the problem by using the newly-introduced generic approach to target delegation for the methods in question. 2014-02-19 Tom Tromey <tromey@redhat.com> * record-full.c (record_full_beneath_to_resume_ops) (record_full_beneath_to_resume, record_full_beneath_to_wait_ops) (record_full_beneath_to_wait) (record_full_beneath_to_store_registers_ops) (record_full_beneath_to_store_registers) (record_full_beneath_to_xfer_partial_ops) (record_full_beneath_to_xfer_partial) (record_full_beneath_to_insert_breakpoint_ops) (record_full_beneath_to_insert_breakpoint) (record_full_beneath_to_remove_breakpoint_ops) (record_full_beneath_to_remove_breakpoint) (record_full_beneath_to_stopped_by_watchpoint) (record_full_beneath_to_stopped_data_address) (record_full_beneath_to_async, tmp_to_resume_ops, tmp_to_resume) (tmp_to_wait_ops, tmp_to_wait, tmp_to_store_registers_ops) (tmp_to_store_registers, tmp_to_xfer_partial_ops) (tmp_to_xfer_partial, tmp_to_instmp_to_insert_breakpoint_ops) (tmp_to_insert_breakpoint, tmp_to_remove_breakpoint_ops) (tmp_to_remove_breakpoint, tmp_to_stopped_by_watchpoint) (tmp_to_stopped_data_address, tmp_to_async): Remove.

fix regressions with target-async A patch in the target cleanup series caused a regression when using record with target-async. Version 4 of the patch is here: https://sourceware.org/ml/gdb-patches/2014-03/msg00159.html The immediate problem is that record supplies to_can_async_p and to_is_async_p methods, but does not supply a to_async method. So, when target-async is set, record claims to support async -- but if the underlying target does not support async, then the to_async method call will end up in that method's default implementation, namely tcomplain. This worked previously because the record target used to provide a to_async method; one that (erroneously, only at push time) checked the other members of the target stack, and then simply dropped to_async calls in the "does not implement async" case. My first thought was to simply drop tcomplain as the default for to_async. This works, but Pedro pointed out that the only reason record has to supply to_can_async_p and to_is_async_p is that these default to using the find_default_run_target machinery -- and these defaults are only needed by "run" and "attach". So, a nicer solution presents itself: change run and attach to explicitly call into the default run target when needed; and change to_is_async_p and to_can_async_p to default to "return 0". This makes the target stack simpler to use and lets us remove the method implementations from record. This is also in harmony with other plans for the target stack; namely trying to reduce the impact of find_default_run_target. This approach makes it clear that find_default_is_async_p is not needed -- it is asking whether a target that may not even be pushed is actually async, which seems like a nonsensical question. While an improvement, this approach proved to introduce the same bug when using the core target. Looking a bit deeper, the issue is that code in "attach" and "run" may need to use either the current target stack or the default run target -- but different calls into the target API in those functions could wind up querying different targets. This new patch makes the target to use more explicit in "run" and "attach". Then these commands explicitly make the needed calls against that target. This ensures that a single target is used for all relevant operations. This lets us remove a couple find_default_* functions from various targets, including the dummy target. I think this is a decent understandability improvement. One issue I see with this patch is that the new calls in "run" and "attach" are not very much like the rest of the target API. I think fundamentally this is due to bad factoring in the target API, which may need to be fixed for multi-target. Tackling that seemed ambitious for a regression fix. While working on this I noticed that there don't seem to be any test cases that involve both target-async and record, so this patch changes break-precsave.exp to add some. It also changes corefile.exp to add some target-async tests; these pass with current trunk and with this patch applied, but fail with the v1 patch. This patch differs from v4 in that it moves initialization of to_can_async_p and to_supports_non_stop into inf-child, adds some assertions to complete_target_initialization, and adds some comments to target.h.

add target method delegation This patch replaces some code in the record targets with target method delegation. record-full.c stores pointers to many target methods when the record target is pushed.

add target method delegation This patch replaces some code in the record targets with target method delegation. record-full.c stores pointers to many target methods when the record target is pushed.

auto-generate most target debug methods The target debug methods are inconsistently maintained. Most to_* methods have some kind of targetdebug awareness, but not all of them do. The ones that do vary in the quantity and quality of output they generate. This patch changes most of the target debug methods to be automatically generated. All the arguments are printed, and separate lines are printed for entering and existing the outermost call to the target stack. For example now you'd see: -> multi-thread->to_terminal_ours (...) -> multi-thread->to_is_async_p (...) <- multi-thread->to_is_async_p (0x1ebb580) = 1 <- multi-thread->to_terminal_ours (0x1ebb580) -> multi-thread->to_thread_address_space (...) <- multi-thread->to_thread_address_space (0x1ebb580, 26802) = 1 In this case you can see nested calls. The "multi-thread" on the left hand side is the topmost target's shortname. There are some oddities with this patch. I'm on the fence about it all, I really just wrote it on a whim. It's not simple to convert every possible method, since a few don't participate in target delegation. Printing is done by type, so I introduced some new debug-printing-specific typedefs to handle cases where it is nicer to do something else. On the plus side, this lays the groundwork for making targetdebug affect every layer of the target stack. The idea would be to wrap each target_ops in the stack with its own debug_target, and then you could see calls propagate down the stack and back up; I suppose with indentation to make it prettier.

auto-generate most target debug methods The target debug methods are inconsistently maintained. Most to_* methods have some kind of targetdebug awareness, but not all of them do. The ones that do vary in the quantity and quality of output they generate. This patch changes most of the target debug methods to be automatically generated. All the arguments are printed, and separate lines are printed for entering and existing the outermost call to the target stack. For example now you'd see: -> multi-thread->to_terminal_ours (...) -> multi-thread->to_is_async_p (...) <- multi-thread->to_is_async_p (0x1ebb580) = 1 <- multi-thread->to_terminal_ours (0x1ebb580) -> multi-thread->to_thread_address_space (...) <- multi-thread->to_thread_address_space (0x1ebb580, 26802) = 1 In this case you can see nested calls. The "multi-thread" on the left hand side is the topmost target's shortname. There are some oddities with this patch. I'm on the fence about it all, I really just wrote it on a whim. It's not simple to convert every possible method, since a few don't participate in target delegation. Printing is done by type, so I introduced some new debug-printing-specific typedefs to handle cases where it is nicer to do something else. On the plus side, this lays the groundwork for making targetdebug affect every layer of the target stack. The idea would be to wrap each target_ops in the stack with its own debug_target, and then you could see calls propagate down the stack and back up; I suppose with indentation to make it prettier.

auto-generate most target debug methods The target debug methods are inconsistently maintained. Most to_* methods have some kind of targetdebug awareness, but not all of them do. The ones that do vary in the quantity and quality of output they generate. This patch changes most of the target debug methods to be automatically generated. All the arguments are printed, and separate lines are printed for entering and existing the outermost call to the target stack. For example now you'd see: -> multi-thread->to_terminal_ours (...) -> multi-thread->to_is_async_p (...) <- multi-thread->to_is_async_p (0x1ebb580) = 1 <- multi-thread->to_terminal_ours (0x1ebb580) -> multi-thread->to_thread_address_space (...) <- multi-thread->to_thread_address_space (0x1ebb580, 26802) = 1 In this case you can see nested calls. The "multi-thread" on the left hand side is the topmost target's shortname. There are some oddities with this patch. I'm on the fence about it all, I really just wrote it on a whim. It's not simple to convert every possible method, since a few don't participate in target delegation. Printing is done by type, so I introduced some new debug-printing-specific typedefs to handle cases where it is nicer to do something else. On the plus side, this lays the groundwork for making targetdebug affect every layer of the target stack. The idea would be to wrap each target_ops in the stack with its own debug_target, and then you could see calls propagate down the stack and back up; I suppose with indentation to make it prettier.

auto-generate most target debug methods The target debug methods are inconsistently maintained. Most to_* methods have some kind of targetdebug awareness, but not all of them do. The ones that do vary in the quantity and quality of output they generate. This patch changes most of the target debug methods to be automatically generated. All the arguments are printed, and separate lines are printed for entering and existing the outermost call to the target stack. For example now you'd see: -> multi-thread->to_terminal_ours (...) -> multi-thread->to_is_async_p (...) <- multi-thread->to_is_async_p (0x1ebb580) = 1 <- multi-thread->to_terminal_ours (0x1ebb580) -> multi-thread->to_thread_address_space (...) <- multi-thread->to_thread_address_space (0x1ebb580, 26802) = 1 In this case you can see nested calls. The "multi-thread" on the left hand side is the topmost target's shortname. There are some oddities with this patch. I'm on the fence about it all, I really just wrote it on a whim. It's not simple to convert every possible method, since a few don't participate in target delegation. Printing is done by type, so I introduced some new debug-printing-specific typedefs to handle cases where it is nicer to do something else. On the plus side, this lays the groundwork for making targetdebug affect every layer of the target stack. The idea would be to wrap each target_ops in the stack with its own debug_target, and then you could see calls propagate down the stack and back up; I suppose with indentation to make it prettier. (That said there are some gotchas lurking in this idea due to target stack introspection.)

auto-generate most target debug methods The target debug methods are inconsistently maintained. Most to_* methods have some kind of targetdebug awareness, but not all of them do. The ones that do vary in the quantity and quality of output they generate. This patch changes most of the target debug methods to be automatically generated. All the arguments are printed, and separate lines are printed for entering and existing the outermost call to the target stack. For example now you'd see: -> multi-thread->to_terminal_ours (...) -> multi-thread->to_is_async_p (...) <- multi-thread->to_is_async_p (0x1ebb580) = 1 <- multi-thread->to_terminal_ours (0x1ebb580) -> multi-thread->to_thread_address_space (...) <- multi-thread->to_thread_address_space (0x1ebb580, 26802) = 1 In this case you can see nested calls. The "multi-thread" on the left hand side is the topmost target's shortname. There are some oddities with this patch. I'm on the fence about it all, I really just wrote it on a whim. It's not simple to convert every possible method, since a few don't participate in target delegation. Printing is done by type, so I introduced some new debug-printing-specific typedefs to handle cases where it is nicer to do something else. On the plus side, this lays the groundwork for making targetdebug affect every layer of the target stack. The idea would be to wrap each target_ops in the stack with its own debug_target, and then you could see calls propagate down the stack and back up; I suppose with indentation to make it prettier.

auto-generate most target debug methods The target debug methods are inconsistently maintained. Most to_* methods have some kind of targetdebug awareness, but not all of them do. The ones that do vary in the quantity and quality of output they generate. This patch changes most of the target debug methods to be automatically generated. All the arguments are printed, and separate lines are printed for entering and existing the outermost call to the target stack. For example now you'd see: -> multi-thread->to_terminal_ours (...) -> multi-thread->to_is_async_p (...) <- multi-thread->to_is_async_p (0x1ebb580) = 1 <- multi-thread->to_terminal_ours (0x1ebb580) -> multi-thread->to_thread_address_space (...) <- multi-thread->to_thread_address_space (0x1ebb580, 26802) = 1 In this case you can see nested calls. The "multi-thread" on the left hand side is the topmost target's shortname. There are some oddities with this patch. I'm on the fence about it all, I really just wrote it on a whim. It's not simple to convert every possible method, since a few don't participate in target delegation. Printing is done by type, so I introduced some new debug-printing-specific typedefs to handle cases where it is nicer to do something else. On the plus side, this lays the groundwork for making targetdebug affect every layer of the target stack. The idea would be to wrap each target_ops in the stack with its own debug_target, and then you could see calls propagate down the stack and back up; I suppose with indentation to make it prettier.

auto-generate most target debug methods The target debug methods are inconsistently maintained. Most to_* methods have some kind of targetdebug awareness, but not all of them do. The ones that do vary in the quantity and quality of output they generate. This patch changes most of the target debug methods to be automatically generated. All the arguments are printed, and separate lines are printed for entering and existing the outermost call to the target stack. For example now you'd see: -> multi-thread->to_terminal_ours (...) -> multi-thread->to_is_async_p (...) <- multi-thread->to_is_async_p (0x1ebb580) = 1 <- multi-thread->to_terminal_ours (0x1ebb580) -> multi-thread->to_thread_address_space (...) <- multi-thread->to_thread_address_space (0x1ebb580, 26802) = 1 In this case you can see nested calls. The "multi-thread" on the left hand side is the topmost target's shortname. There are some oddities with this patch. I'm on the fence about it all, I really just wrote it on a whim. It's not simple to convert every possible method, since a few don't participate in target delegation. Printing is done by type, so I introduced some new debug-printing-specific typedefs to handle cases where it is nicer to do something else. On the plus side, this lays the groundwork for making targetdebug affect every layer of the target stack. The idea would be to wrap each target_ops in the stack with its own debug_target, and then you could see calls propagate down the stack and back up; I suppose with indentation to make it prettier.

auto-generate most target debug methods The target debug methods are inconsistently maintained. Most to_* methods have some kind of targetdebug awareness, but not all of them do. The ones that do vary in the quantity and quality of output they generate. This patch changes most of the target debug methods to be automatically generated. All the arguments are printed, and separate lines are printed for entering and existing the outermost call to the target stack. For example now you'd see: -> multi-thread->to_terminal_ours (...) -> multi-thread->to_is_async_p (...) <- multi-thread->to_is_async_p (0x1ebb580) = 1 <- multi-thread->to_terminal_ours (0x1ebb580) -> multi-thread->to_thread_address_space (...) <- multi-thread->to_thread_address_space (0x1ebb580, 26802) = 1 In this case you can see nested calls. The "multi-thread" on the left hand side is the topmost target's shortname. There are some oddities with this patch. I'm on the fence about it all, I really just wrote it on a whim. It's not simple to convert every possible method, since a few don't participate in target delegation. Printing is done by type, so I introduced some new debug-printing-specific typedefs to handle cases where it is nicer to do something else. On the plus side, this lays the groundwork for making targetdebug affect every layer of the target stack. The idea would be to wrap each target_ops in the stack with its own debug_target, and then you could see calls propagate down the stack and back up; I suppose with indentation to make it prettier.

auto-generate most target debug methods The target debug methods are inconsistently maintained. Most to_* methods have some kind of targetdebug awareness, but not all of them do. The ones that do vary in the quantity and quality of output they generate. This patch changes most of the target debug methods to be automatically generated. All the arguments are printed, and separate lines are printed for entering and existing the outermost call to the target stack. For example now you'd see: -> multi-thread->to_terminal_ours (...) -> multi-thread->to_is_async_p (...) <- multi-thread->to_is_async_p (0x1ebb580) = 1 <- multi-thread->to_terminal_ours (0x1ebb580) -> multi-thread->to_thread_address_space (...) <- multi-thread->to_thread_address_space (0x1ebb580, 26802) = 1 In this case you can see nested calls. The "multi-thread" on the left hand side is the topmost target's shortname. There are some oddities with this patch. I'm on the fence about it all, I really just wrote it on a whim. It's not simple to convert every possible method, since a few don't participate in target delegation. Printing is done by type, so I introduced some new debug-printing-specific typedefs to handle cases where it is nicer to do something else. On the plus side, this lays the groundwork for making targetdebug affect every layer of the target stack. The idea would be to wrap each target_ops in the stack with its own debug_target, and then you could see calls propagate down the stack and back up; I suppose with indentation to make it prettier.

auto-generate most target debug methods The target debug methods are inconsistently maintained. Most to_* methods have some kind of targetdebug awareness, but not all of them do. The ones that do vary in the quantity and quality of output they generate. This patch changes most of the target debug methods to be automatically generated. All the arguments are printed, and separate lines are printed for entering and existing the outermost call to the target stack. For example now you'd see: -> multi-thread->to_terminal_ours (...) -> multi-thread->to_is_async_p (...) <- multi-thread->to_is_async_p (0x1ebb580) = 1 <- multi-thread->to_terminal_ours (0x1ebb580) -> multi-thread->to_thread_address_space (...) <- multi-thread->to_thread_address_space (0x1ebb580, 26802) = 1 In this case you can see nested calls. The "multi-thread" on the left hand side is the topmost target's shortname. There are some oddities with this patch. I'm on the fence about it all, I really just wrote it on a whim. It's not simple to convert every possible method, since a few don't participate in target delegation. Printing is done by type, so I introduced some new debug-printing-specific typedefs to handle cases where it is nicer to do something else. On the plus side, this lays the groundwork for making targetdebug affect every layer of the target stack. The idea would be to wrap each target_ops in the stack with its own debug_target, and then you could see calls propagate down the stack and back up; I suppose with indentation to make it prettier. (That said there are some gotchas lurking in this idea due to target stack introspection.)

auto-generate most target debug methods The target debug methods are inconsistently maintained. Most to_* methods have some kind of targetdebug awareness, but not all of them do. The ones that do vary in the quantity and quality of output they generate. This patch changes most of the target debug methods to be automatically generated. All the arguments are printed, and separate lines are printed for entering and existing the outermost call to the target stack. For example now you'd see: -> multi-thread->to_terminal_ours (...) -> multi-thread->to_is_async_p (...) <- multi-thread->to_is_async_p (0x1ebb580) = 1 <- multi-thread->to_terminal_ours (0x1ebb580) -> multi-thread->to_thread_address_space (...) <- multi-thread->to_thread_address_space (0x1ebb580, 26802) = 1 In this case you can see nested calls. The "multi-thread" on the left hand side is the topmost target's shortname. There are some oddities with this patch. I'm on the fence about it all, I really just wrote it on a whim. It's not simple to convert every possible method, since a few don't participate in target delegation. Printing is done by type, so I introduced some new debug-printing-specific typedefs to handle cases where it is nicer to do something else. On the plus side, this lays the groundwork for making targetdebug affect every layer of the target stack. The idea would be to wrap each target_ops in the stack with its own debug_target, and then you could see calls propagate down the stack and back up; I suppose with indentation to make it prettier. (That said there are some gotchas lurking in this idea due to target stack introspection.)

record btrace: add configuration struct Add a struct to describe the branch trace configuration and use it for enabling branch tracing. The user will be able to set configuration fields for each tracing format to be used for new threads. The actual configuration that is active for a given thread will be shown in the "info record" command. At the moment, the configuration struct only contains a format field that is set to the only available format. The format is the only configuration option that can not be set via set commands.

auto-generate most target debug methods The target debug methods are inconsistently maintained. Most to_* methods have some kind of targetdebug awareness, but not all of them do. The ones that do vary in the quantity and quality of output they generate. This patch changes most of the target debug methods to be automatically generated. All the arguments are printed, and separate lines are printed for entering and existing the outermost call to the target stack. For example now you'd see: -> multi-thread->to_terminal_ours (...) -> multi-thread->to_is_async_p (...) <- multi-thread->to_is_async_p (0x1ebb580) = 1 <- multi-thread->to_terminal_ours (0x1ebb580) -> multi-thread->to_thread_address_space (...) <- multi-thread->to_thread_address_space (0x1ebb580, 26802) = 1 In this case you can see nested calls. The "multi-thread" on the left hand side is the topmost target's shortname. There are some oddities with this patch. I'm on the fence about it all, I really just wrote it on a whim. It's not simple to convert every possible method, since a few don't participate in target delegation. Printing is done by type, so I introduced some new debug-printing-specific typedefs to handle cases where it is nicer to do something else. On the plus side, this lays the groundwork for making targetdebug affect every layer of the target stack. The idea would be to wrap each target_ops in the stack with its own debug_target, and then you could see calls propagate down the stack and back up; I suppose with indentation to make it prettier.

debug_read_btrace (struct target_ops *self, struct btrace_data *arg1, struct btrace_target_info *arg2, enum btrace_read_type arg3)
auto-generate most target debug methods The target debug methods are inconsistently maintained. Most to_* methods have some kind of targetdebug awareness, but not all of them do. The ones that do vary in the quantity and quality of output they generate. This patch changes most of the target debug methods to be automatically generated. All the arguments are printed, and separate lines are printed for entering and existing the outermost call to the target stack. For example now you'd see: -> multi-thread->to_terminal_ours (...) -> multi-thread->to_is_async_p (...) <- multi-thread->to_is_async_p (0x1ebb580) = 1 <- multi-thread->to_terminal_ours (0x1ebb580) -> multi-thread->to_thread_address_space (...) <- multi-thread->to_thread_address_space (0x1ebb580, 26802) = 1 In this case you can see nested calls. The "multi-thread" on the left hand side is the topmost target's shortname. There are some oddities with this patch. I'm on the fence about it all, I really just wrote it on a whim. It's not simple to convert every possible method, since a few don't participate in target delegation. Printing is done by type, so I introduced some new debug-printing-specific typedefs to handle cases where it is nicer to do something else. On the plus side, this lays the groundwork for making targetdebug affect every layer of the target stack. The idea would be to wrap each target_ops in the stack with its own debug_target, and then you could see calls propagate down the stack and back up; I suppose with indentation to make it prettier.

record btrace: add configuration struct Add a struct to describe the branch trace configuration and use it for enabling branch tracing. The user will be able to set configuration fields for each tracing format to be used for new threads. The actual configuration that is active for a given thread will be shown in the "info record" command. At the moment, the configuration struct only contains a format field that is set to the only available format. The format is the only configuration option that can not be set via set commands. It is given as argument to the "record btrace" command when starting recording. 2015-02-09 Markus Metzger <markus.t.metzger@intel.com> * Makefile.in (XMLFILES): Add btrace-conf.dtd. * x86-linux-nat.c (x86_linux_enable_btrace): Update parameters.

auto-generate most target debug methods The target debug methods are inconsistently maintained. Most to_* methods have some kind of targetdebug awareness, but not all of them do. The ones that do vary in the quantity and quality of output they generate. This patch changes most of the target debug methods to be automatically generated. All the arguments are printed, and separate lines are printed for entering and existing the outermost call to the target stack. For example now you'd see: -> multi-thread->to_terminal_ours (...) -> multi-thread->to_is_async_p (...) <- multi-thread->to_is_async_p (0x1ebb580) = 1 <- multi-thread->to_terminal_ours (0x1ebb580) -> multi-thread->to_thread_address_space (...) <- multi-thread->to_thread_address_space (0x1ebb580, 26802) = 1 In this case you can see nested calls. The "multi-thread" on the left hand side is the topmost target's shortname. There are some oddities with this patch. I'm on the fence about it all, I really just wrote it on a whim. It's not simple to convert every possible method, since a few don't participate in target delegation. Printing is done by type, so I introduced some new debug-printing-specific typedefs to handle cases where it is nicer to do something else. On the plus side, this lays the groundwork for making targetdebug affect every layer of the target stack. The idea would be to wrap each target_ops in the stack with its own debug_target, and then you could see calls propagate down the stack and back up; I suppose with indentation to make it prettier.

auto-generate most target debug methods The target debug methods are inconsistently maintained. Most to_* methods have some kind of targetdebug awareness, but not all of them do. The ones that do vary in the quantity and quality of output they generate. This patch changes most of the target debug methods to be automatically generated. All the arguments are printed, and separate lines are printed for entering and existing the outermost call to the target stack. For example now you'd see: -> multi-thread->to_terminal_ours (...) -> multi-thread->to_is_async_p (...) <- multi-thread->to_is_async_p (0x1ebb580) = 1 <- multi-thread->to_terminal_ours (0x1ebb580) -> multi-thread->to_thread_address_space (...) <- multi-thread->to_thread_address_space (0x1ebb580, 26802) = 1 In this case you can see nested calls. The "multi-thread" on the left hand side is the topmost target's shortname. There are some oddities with this patch. I'm on the fence about it all, I really just wrote it on a whim. It's not simple to convert every possible method, since a few don't participate in target delegation. Printing is done by type, so I introduced some new debug-printing-specific typedefs to handle cases where it is nicer to do something else. On the plus side, this lays the groundwork for making targetdebug affect every layer of the target stack. The idea would be to wrap each target_ops in the stack with its own debug_target, and then you could see calls propagate down the stack and back up; I suppose with indentation to make it prettier.

auto-generate most target debug methods The target debug methods are inconsistently maintained. Most to_* methods have some kind of targetdebug awareness, but not all of them do. The ones that do vary in the quantity and quality of output they generate. This patch changes most of the target debug methods to be automatically generated. All the arguments are printed, and separate lines are printed for entering and existing the outermost call to the target stack. For example now you'd see: -> multi-thread->to_terminal_ours (...) -> multi-thread->to_is_async_p (...) <- multi-thread->to_is_async_p (0x1ebb580) = 1 <- multi-thread->to_terminal_ours (0x1ebb580) -> multi-thread->to_thread_address_space (...) <- multi-thread->to_thread_address_space (0x1ebb580, 26802) = 1 In this case you can see nested calls. The "multi-thread" on the left hand side is the topmost target's shortname. There are some oddities with this patch. I'm on the fence about it all, I really just wrote it on a whim. It's not simple to convert every possible method, since a few don't participate in target delegation. Printing is done by type, so I introduced some new debug-printing-specific typedefs to handle cases where it is nicer to do something else. On the plus side, this lays the groundwork for making targetdebug affect every layer of the target stack. The idea would be to wrap each target_ops in the stack with its own debug_target, and then you could see calls propagate down the stack and back up; I suppose with indentation to make it prettier. (That said there are some gotchas lurking in this idea due to target stack introspection.)

add target method delegation This patch replaces some code in the record targets with target method delegation. record-full.c stores pointers to many target methods when the record target is pushed. Then it later delegates some calls via these. This is wrong because it violates the target stack contract. In particular it is ok to unpush a target at any stratum, but record-full does not keep track of this, so it could potentially call into an unpushed target.

Push pruning old threads down to the target When GDB wants to sync the thread list with the target's (e.g., due to "info threads"), it calls update_thread_list: update_thread_list (void) { prune_threads (); target_find_new_threads (); update_threads_executing (); } And then prune_threads does: prune_threads (void) { struct thread_info *tp, *next; for (tp = thread_list; tp; tp = next) { next = tp->next; if (!thread_alive (tp)) delete_thread (tp->ptid); } } Calling thread_live on each thread one by one is expensive. E.g., on Linux, it ends up doing kill(SIG0) once for each thread. Not a big deal, but still a bunch of syscalls... With the remote target, it's cumbersome. That thread_alive call ends up generating one T packet per thread: Sending packet: $Tp2141.2150#82...Packet received: OK Sending packet: $Tp2141.214f#b7...Packet received: OK Sending packet: $Tp2141.2141#82...Packet received: OK Sending packet: $qXfer:threads:read::0,fff#03...Packet received: l<threads>\n<thread id="p2141.2141" core="2"/>\n<thread id="p2141.214f" core="1"/>\n<thread id="p2141.2150" core="2"/>\n</threads>\n That seems a bit silly when target_find_new_threads method implementations will always fetch the whole current set of target threads, and then add those that are not in GDB's thread list, to GDB's thread list. This patch thus pushes down the responsibility of pruning dead threads to the target_find_new_threads method instead, so a target may implement pruning dead threads however it wants. Once we do that, target_find_new_threads becomes a misnomer, so the patch renames it to target_update_thread_list. The patch doesn't attempt to do any optimization to any target yet. It simply exports prune_threads, and makes all implementations of target_update_thread_list call that.

add target method delegation This patch replaces some code in the record targets with target method delegation. record-full.c stores pointers to many target methods when the record target is pushed. Then it later delegates some calls via these. This is wrong because it violates the target stack contract. In particular it is ok to unpush a target at any stratum, but record-full does not keep track of this, so it could potentially call into an unpushed target. This patch fixes the problem by using the newly-introduced generic approach to target delegation for the methods in question. 2014-02-19 Tom Tromey <tromey@redhat.com> * record-full.c (record_full_beneath_to_resume_ops) (record_full_beneath_to_resume, record_full_beneath_to_wait_ops) (record_full_beneath_to_wait) (record_full_beneath_to_store_registers_ops) (record_full_beneath_to_store_registers) (record_full_beneath_to_xfer_partial_ops) (record_full_beneath_to_xfer_partial) (record_full_beneath_to_insert_breakpoint_ops) (record_full_beneath_to_insert_breakpoint) (record_full_beneath_to_remove_breakpoint_ops) (record_full_beneath_to_remove_breakpoint) (record_full_beneath_to_stopped_by_watchpoint) (record_full_beneath_to_stopped_data_address) (record_full_beneath_to_async, tmp_to_resume_ops, tmp_to_resume) (tmp_to_wait_ops, tmp_to_wait, tmp_to_store_registers_ops) (tmp_to_store_registers, tmp_to_xfer_partial_ops) (tmp_to_xfer_partial, tmp_to_instmp_to_insert_breakpoint_ops) (tmp_to_insert_breakpoint, tmp_to_remove_breakpoint_ops) (tmp_to_remove_breakpoint, tmp_to_stopped_by_watchpoint) (tmp_to_stopped_data_address, tmp_to_async): Remove.

fix regressions with target-async A patch in the target cleanup series caused a regression when using record with target-async. Version 4 of the patch is here: https://sourceware.org/ml/gdb-patches/2014-03/msg00159.html The immediate problem is that record supplies to_can_async_p and to_is_async_p methods, but does not supply a to_async method. So, when target-async is set, record claims to support async -- but if the underlying target does not support async, then the to_async method call will end up in that method's default implementation, namely tcomplain. This worked previously because the record target used to provide a to_async method; one that (erroneously, only at push time) checked the other members of the target stack, and then simply dropped to_async calls in the "does not implement async" case. My first thought was to simply drop tcomplain as the default for to_async. This works, but Pedro pointed out that the only reason record has to supply to_can_async_p and to_is_async_p is that these default to using the find_default_run_target machinery -- and these defaults are only needed by "run" and "attach". So, a nicer solution presents itself: change run and attach to explicitly call into the default run target when needed; and change to_is_async_p and to_can_async_p to default to "return 0". This makes the target stack simpler to use and lets us remove the method implementations from record. This is also in harmony with other plans for the target stack; namely trying to reduce the impact of find_default_run_target. This approach makes it clear that find_default_is_async_p is not needed -- it is asking whether a target that may not even be pushed is actually async, which seems like a nonsensical question. While an improvement, this approach proved to introduce the same bug when using the core target. Looking a bit deeper, the issue is that code in "attach" and "run" may need to use either the current target stack or the default run target -- but different calls into the target API in those functions could wind up querying different targets. This new patch makes the target to use more explicit in "run" and "attach". Then these commands explicitly make the needed calls against that target. This ensures that a single target is used for all relevant operations. This lets us remove a couple find_default_* functions from various targets, including the dummy target. I think this is a decent understandability improvement. One issue I see with this patch is that the new calls in "run" and "attach" are not very much like the rest of the target API. I think fundamentally this is due to bad factoring in the target API, which may need to be fixed for multi-target. Tackling that seemed ambitious for a regression fix. While working on this I noticed that there don't seem to be any test cases that involve both target-async and record, so this patch changes break-precsave.exp to add some. It also changes corefile.exp to add some target-async tests; these pass with current trunk and with this patch applied, but fail with the v1 patch. This patch differs from v4 in that it moves initialization of to_can_async_p and to_supports_non_stop into inf-child, adds some assertions to complete_target_initialization, and adds some comments to target.h.

record btrace: add configuration struct Add a struct to describe the branch trace configuration and use it for enabling branch tracing. The user will be able to set configuration fields for each tracing format to be used for new threads. The actual configuration that is active for a given thread will be shown in the "info record" command. At the moment, the configuration struct only contains a format field that is set to the only available format. The format is the only configuration option that can not be set via set commands. It is given as argument to the "record btrace" command when starting recording. 2015-02-09 Markus Metzger <markus.t.metzger@intel.com> * Makefile.in (XMLFILES): Add btrace-conf.dtd. * x86-linux-nat.c (x86_linux_enable_btrace): Update parameters.

add target method delegation This patch replaces some code in the record targets with target method delegation. record-full.c stores pointers to many target methods when the record target is pushed. Then it later delegates some calls via these. This is wrong because it violates the target stack contract. In particular it is ok to unpush a target at any stratum, but record-full does not keep track of this, so it could potentially call into an unpushed target. This patch fixes the problem by using the newly-introduced generic approach to target delegation for the methods in question. 2014-02-19 Tom Tromey <tromey@redhat.com> * record-full.c (record_full_beneath_to_resume_ops) (record_full_beneath_to_resume, record_full_beneath_to_wait_ops) (record_full_beneath_to_wait) (record_full_beneath_to_store_registers_ops) (record_full_beneath_to_store_registers) (record_full_beneath_to_xfer_partial_ops) (record_full_beneath_to_xfer_partial) (record_full_beneath_to_insert_breakpoint_ops) (record_full_beneath_to_insert_breakpoint) (record_full_beneath_to_remove_breakpoint_ops) (record_full_beneath_to_remove_breakpoint) (record_full_beneath_to_stopped_by_watchpoint) (record_full_beneath_to_stopped_data_address) (record_full_beneath_to_async, tmp_to_resume_ops, tmp_to_resume) (tmp_to_wait_ops, tmp_to_wait, tmp_to_store_registers_ops) (tmp_to_store_registers, tmp_to_xfer_partial_ops) (tmp_to_xfer_partial, tmp_to_instmp_to_insert_breakpoint_ops) (tmp_to_insert_breakpoint, tmp_to_remove_breakpoint_ops) (tmp_to_remove_breakpoint, tmp_to_stopped_by_watchpoint) (tmp_to_stopped_data_address, tmp_to_async): Remove.

Push pruning old threads down to the target When GDB wants to sync the thread list with the target's (e.g., due to "info threads"), it calls update_thread_list: update_thread_list (void) { prune_threads (); target_find_new_threads (); update_threads_executing (); } And then prune_threads does: prune_threads (void) { struct thread_info *tp, *next; for (tp = thread_list; tp; tp = next) { next = tp->next; if (!thread_alive (tp)) delete_thread (tp->ptid); } } Calling thread_live on each thread one by one is expensive. E.g., on Linux, it ends up doing kill(SIG0) once for each thread. Not a big deal, but still a bunch of syscalls... With the remote target, it's cumbersome. That thread_alive call ends up generating one T packet per thread: Sending packet: $Tp2141.2150#82...Packet received: OK Sending packet: $Tp2141.214f#b7...Packet received: OK Sending packet: $Tp2141.2141#82...Packet received: OK Sending packet: $qXfer:threads:read::0,fff#03...Packet received: l<threads>\n<thread id="p2141.2141" core="2"/>\n<thread id="p2141.214f" core="1"/>\n<thread id="p2141.2150" core="2"/>\n</threads>\n That seems a bit silly when target_find_new_threads method implementations will always fetch the whole current set of target threads, and then add those that are not in GDB's thread list, to GDB's thread list. This patch thus pushes down the responsibility of pruning dead threads to the target_find_new_threads method instead, so a target may implement pruning dead threads however it wants. Once we do that, target_find_new_threads becomes a misnomer, so the patch renames it to target_update_thread_list. The patch doesn't attempt to do any optimization to any target yet. It simply exports prune_threads, and makes all implementations of target_update_thread_list call that.

fix regressions with target-async A patch in the target cleanup series caused a regression when using record with target-async. Version 4 of the patch is here: https://sourceware.org/ml/gdb-patches/2014-03/msg00159.html The immediate problem is that record supplies to_can_async_p and to_is_async_p methods, but does not supply a to_async method. So, when target-async is set, record claims to support async -- but if the underlying target does not support async, then the to_async method call will end up in that method's default implementation, namely tcomplain. This worked previously because the record target used to provide a to_async method; one that (erroneously, only at push time) checked the other members of the target stack, and then simply dropped to_async calls in the "does not implement async" case. My first thought was to simply drop tcomplain as the default for to_async. This works, but Pedro pointed out that the only reason record has to supply to_can_async_p and to_is_async_p is that these default to using the find_default_run_target machinery -- and these defaults are only needed by "run" and "attach". So, a nicer solution presents itself: change run and attach to explicitly call into the default run target when needed; and change to_is_async_p and to_can_async_p to default to "return 0". This makes the target stack simpler to use and lets us remove the method implementations from record. This is also in harmony with other plans for the target stack; namely trying to reduce the impact of find_default_run_target. This approach makes it clear that find_default_is_async_p is not needed -- it is asking whether a target that may not even be pushed is actually async, which seems like a nonsensical question. While an improvement, this approach proved to introduce the same bug when using the core target. Looking a bit deeper, the issue is that code in "attach" and "run" may need to use either the current target stack or the default run target -- but different calls into the target API in those functions could wind up querying different targets. This new patch makes the target to use more explicit in "run" and "attach". Then these commands explicitly make the needed calls against that target. This ensures that a single target is used for all relevant operations. This lets us remove a couple find_default_* functions from various targets, including the dummy target. I think this is a decent understandability improvement. One issue I see with this patch is that the new calls in "run" and "attach" are not very much like the rest of the target API. I think fundamentally this is due to bad factoring in the target API, which may need to be fixed for multi-target. Tackling that seemed ambitious for a regression fix. While working on this I noticed that there don't seem to be any test cases that involve both target-async and record, so this patch changes break-precsave.exp to add some. It also changes corefile.exp to add some target-async tests; these pass with current trunk and with this patch applied, but fail with the v1 patch. This patch differs from v4 in that it moves initialization of to_can_async_p and to_supports_non_stop into inf-child, adds some assertions to complete_target_initialization, and adds some comments to target.h.

add target method delegation This patch replaces some code in the record targets with target method delegation. record-full.c stores pointers to many target methods when the record target is pushed. Then it later delegates some calls via these. This is wrong because it violates the target stack contract. In particular it is ok to unpush a target at any stratum, but record-full does not keep track of this, so it could potentially call into an unpushed target. This patch fixes the problem by using the newly-introduced generic approach to target delegation for the methods in question. 2014-02-19 Tom Tromey <tromey@redhat.com> * record-full.c (record_full_beneath_to_resume_ops) (record_full_beneath_to_resume, record_full_beneath_to_wait_ops) (record_full_beneath_to_wait) (record_full_beneath_to_store_registers_ops) (record_full_beneath_to_store_registers) (record_full_beneath_to_xfer_partial_ops) (record_full_beneath_to_xfer_partial) (record_full_beneath_to_insert_breakpoint_ops) (record_full_beneath_to_insert_breakpoint) (record_full_beneath_to_remove_breakpoint_ops) (record_full_beneath_to_remove_breakpoint) (record_full_beneath_to_stopped_by_watchpoint) (record_full_beneath_to_stopped_data_address) (record_full_beneath_to_async, tmp_to_resume_ops, tmp_to_resume) (tmp_to_wait_ops, tmp_to_wait, tmp_to_store_registers_ops) (tmp_to_store_registers, tmp_to_xfer_partial_ops) (tmp_to_xfer_partial, tmp_to_instmp_to_insert_breakpoint_ops) (tmp_to_insert_breakpoint, tmp_to_remove_breakpoint_ops) (tmp_to_remove_breakpoint, tmp_to_stopped_by_watchpoint) (tmp_to_stopped_data_address, tmp_to_async): Remove.

Make compare-sections work against all targets; add compare-sections [-r] tests. This does two things: 1. Adds a test. Recently compare-sections got a new "-r" switch, but given no test existed for compare-sections, the patch was allowed in with no testsuite addition. This now adds a test for both compare-sections and compare-sections -r. 2. Makes the compare-sections command work against all targets. Currently, compare-sections only works with remote targets, and only those that support the qCRC packet. The patch makes it so that if the target doesn't support accelerating memory verification, then GDB falls back to comparing memory itself. This is of course slower, but it's better than nothing, IMO. While testing against extended-remote GDBserver I noticed that we send the qCRC request to the target if we're connected, but not yet running a program. That can't work of course -- the patch fixes that. This all also goes in the direction of bridging the local/remote parity gap. I didn't decouple 1. from 2., because that would mean that the test would need to handle the case of the target not supporting the command. Tested on x86_64 Fedora 17, native, remote GDBserver, and extended-remote GDBserver. I also hack-disabled qCRC support to make sure the fallback paths in remote.c work. gdb/doc/ 2014-05-20 Pedro Alves <palves@redhat.com> * gdb.texinfo (Memory) <compare-sections>: Generalize comments to not be remote specific.

record btrace: add configuration struct Add a struct to describe the branch trace configuration and use it for enabling branch tracing. The user will be able to set configuration fields for each tracing format to be used for new threads. The actual configuration that is active for a given thread will be shown in the "info record" command. At the moment, the configuration struct only contains a format field that is set to the only available format. The format is the only configuration option that can not be set via set commands. It is given as argument to the "record btrace" command when starting recording. 2015-02-09 Markus Metzger <markus.t.metzger@intel.com> * Makefile.in (XMLFILES): Add btrace-conf.dtd. * x86-linux-nat.c (x86_linux_enable_btrace): Update parameters.

auto-generate most target debug methods The target debug methods are inconsistently maintained. Most to_* methods have some kind of targetdebug awareness, but not all of them do. The ones that do vary in the quantity and quality of output they generate. This patch changes most of the target debug methods to be automatically generated. All the arguments are printed, and separate lines are printed for entering and existing the outermost call to the target stack. For example now you'd see: -> multi-thread->to_terminal_ours (...) -> multi-thread->to_is_async_p (...) <- multi-thread->to_is_async_p (0x1ebb580) = 1 <- multi-thread->to_terminal_ours (0x1ebb580) -> multi-thread->to_thread_address_space (...) <- multi-thread->to_thread_address_space (0x1ebb580, 26802) = 1 In this case you can see nested calls. The "multi-thread" on the left hand side is the topmost target's shortname. There are some oddities with this patch. I'm on the fence about it all, I really just wrote it on a whim. It's not simple to convert every possible method, since a few don't participate in target delegation. Printing is done by type, so I introduced some new debug-printing-specific typedefs to handle cases where it is nicer to do something else. On the plus side, this lays the groundwork for making targetdebug affect every layer of the target stack. The idea would be to wrap each target_ops in the stack with its own debug_target, and then you could see calls propagate down the stack and back up; I suppose with indentation to make it prettier. (That said there are some gotchas lurking in this idea due to target stack introspection.)

Push pruning old threads down to the target When GDB wants to sync the thread list with the target's (e.g., due to "info threads"), it calls update_thread_list: update_thread_list (void) { prune_threads (); target_find_new_threads (); update_threads_executing (); } And then prune_threads does: prune_threads (void) { struct thread_info *tp, *next; for (tp = thread_list; tp; tp = next) { next = tp->next; if (!thread_alive (tp)) delete_thread (tp->ptid); } } Calling thread_live on each thread one by one is expensive. E.g., on Linux, it ends up doing kill(SIG0) once for each thread. Not a big deal, but still a bunch of syscalls... With the remote target, it's cumbersome. That thread_alive call ends up generating one T packet per thread: Sending packet: $Tp2141.2150#82...Packet received: OK Sending packet: $Tp2141.214f#b7...Packet received: OK Sending packet: $Tp2141.2141#82...Packet received: OK Sending packet: $qXfer:threads:read::0,fff#03...Packet received: l<threads>\n<thread id="p2141.2141" core="2"/>\n<thread id="p2141.214f" core="1"/>\n<thread id="p2141.2150" core="2"/>\n</threads>\n That seems a bit silly when target_find_new_threads method implementations will always fetch the whole current set of target threads, and then add those that are not in GDB's thread list, to GDB's thread list. This patch thus pushes down the responsibility of pruning dead threads to the target_find_new_threads method instead, so a target may implement pruning dead threads however it wants. Once we do that, target_find_new_threads becomes a misnomer, so the patch renames it to target_update_thread_list. The patch doesn't attempt to do any optimization to any target yet. It simply exports prune_threads, and makes all implementations of target_update_thread_list call that.

record btrace: add configuration struct Add a struct to describe the branch trace configuration and use it for enabling branch tracing. The user will be able to set configuration fields for each tracing format to be used for new threads. The actual configuration that is active for a given thread will be shown in the "info record" command. At the moment, the configuration struct only contains a format field that is set to the only available format. The format is the only configuration option that can not be set via set commands. It is given as argument to the "record btrace" command when starting recording. 2015-02-09 Markus Metzger <markus.t.metzger@intel.com> * Makefile.in (XMLFILES): Add btrace-conf.dtd. * x86-linux-nat.c (x86_linux_enable_btrace): Update parameters.

auto-generate most target debug methods The target debug methods are inconsistently maintained. Most to_* methods have some kind of targetdebug awareness, but not all of them do. The ones that do vary in the quantity and quality of output they generate. This patch changes most of the target debug methods to be automatically generated. All the arguments are printed, and separate lines are printed for entering and existing the outermost call to the target stack. For example now you'd see: -> multi-thread->to_terminal_ours (...) -> multi-thread->to_is_async_p (...) <- multi-thread->to_is_async_p (0x1ebb580) = 1 <- multi-thread->to_terminal_ours (0x1ebb580) -> multi-thread->to_thread_address_space (...) <- multi-thread->to_thread_address_space (0x1ebb580, 26802) = 1 In this case you can see nested calls. The "multi-thread" on the left hand side is the topmost target's shortname. There are some oddities with this patch. I'm on the fence about it all, I really just wrote it on a whim. It's not simple to convert every possible method, since a few don't participate in target delegation. Printing is done by type, so I introduced some new debug-printing-specific typedefs to handle cases where it is nicer to do something else. On the plus side, this lays the groundwork for making targetdebug affect every layer of the target stack. The idea would be to wrap each target_ops in the stack with its own debug_target, and then you could see calls propagate down the stack and back up; I suppose with indentation to make it prettier. (That said there are some gotchas lurking in this idea due to target stack introspection.)
