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.

auto-generate most target debug methods
The target debug methods are inconsistently maintained. Most to_*

This patch changes most of the target debug methods to be

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.

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

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.

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.

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.)
Regtested on x86-64 Fedora 20.

Teach GDB about targets that can tell whether a trap is a breakpoint event
The moribund locations heuristics are problematic. This patch teaches
GDB about targets that can reliably tell whether a trap was caused by
a software or hardware breakpoint, and thus don't need moribund
locations, thus bypassing all the problems that mechanism has.
The non-stop-fair-events.exp test is frequently failing currently.
E.g., see https://sourceware.org/ml/gdb-testers/2015-q1/msg03148.html.
The root cause is a fundamental problem with moribund locations. For
example, the stepped_breakpoint logic added by af48d08f breaks in this
case (which is what happens with that test):
- Step thread A, no breakpoint is set at PC.
- The kernel doesn't schedule thread A yet.
- Insert breakpoint at A's PC, for some reason (e.g., a step-resume
breakpoint for thread B).
- Kernel finally schedules thread A.
- thread A's stepped_breakpoint flag is not set, even though it now
stepped a breakpoint instruction.
- adjust_pc_after_break gets the PC wrong, because PC == PREV_PC, but
stepped_breakpoint is not set.
We needed the stepped_breakpoint logic to workaround moribund
locations, because otherwise adjust_pc_after_break could apply an
adjustment when it shouldn't just because there _used_ to be a
breakpoint at PC (a moribund breakpoint location). For example, on
x86, that's wrong if the thread really hasn't executed an int3, but
instead executed some other 1-byte long instruction. Getting the PC
adjustment wrong of course leads to the inferior executing the wrong
instruction.
Other problems with moribund locations are:
- if a true SIGTRAP happens to be raised when the program is
executing the PC that used to have a breakpoint, GDB will assume
that is a trap for a breakpoint that has recently been removed, and
thus we miss reporting the random signal to the user.
- to minimize that, we get rid of moribund location after a while.
That while is defined as just a certain number of events being
processed. That number of events sometimes passes by before a
delayed breakpoint is processed, and GDB confuses the trap for a
random signal, thus reporting the random trap. Once the user
resumes the thread, the program crashes because the PC was not
adjusted...
The fix for all this is to bite the bullet and get rid of heuristics
and instead rely on the target knowing accurately what caused the
SIGTRAP. The target/kernel/stub is in the best position to know what
that, because it can e.g. consult priviledged CPU flags GDB has no
access to, or by knowing which exception vector entry was called when
the instruction trapped, etc. Most debug APIs I've seen to date
report breakpoint hits as a distinct event in some fashion. For
example, on the Linux kernel, whether a breakpoint was executed is
exposed to userspace in the si_code field of the SIGTRAP's siginfo.
On Windows, the debug API reports a EXCEPTION_BREAKPOINT exception
code.
We needed to keep around deleted breakpoints in an on-the-side list
(the moribund locations) for two main reasons:
- Know that a SIGTRAP actually is a delayed event for a hit of a
breakpoint that was removed before the event was processed, and
thus should not be reported as a random signal.
- So we still do the decr_pc_after_break adjustment in that case, so
that the thread is resumed at the correct address.
In the new model, if GDB processes an event the target tells is a
breakpoint trap, and GDB doesn't find the corresponding breakpoint in
its breakpoint tables, it means that event is a delayed event for a
breakpoint that has since been removed, and thus the event should be
ignored.
For the decr_pc_after_after issue, it ends up being much simpler that
on targets that can reliably tell whether a breakpoint trapped, for
the breakpoint trap to present the PC already adjusted. Proper
multi-threading support already implies that targets needs to be doing
decr_pc_after_break adjustment themselves, otherwise for example, in
all-stop if two threads hit a breakpoint simultaneously, and the user
does "info threads", he'll see the non-event thread that hit the
breakpoint stopped at the wrong PC.
This way (target adjusts) also ends up eliminating the need for some
awkward re-incrementing of the PC in the record-full and Linux targets
that we do today, and the need for the target_decr_pc_after_break
hook.
If the target always adjusts, then there's a case where GDB needs to
re-increment the PC. Say, on x86, an "int3" instruction that was
explicitly written in the program traps. In this case, GDB should
report a random SIGTRAP signal to the user, with the PC pointing at
the instruction past the int3, just like if GDB was not debugging the
program. The user may well decide to pass the SIGTRAP to the program
because the program being debugged has a SIGTRAP handler that handles
its own breakpoints, and expects the PC to be unadjusted.
Tested on x86-64 Fedora 20.

tells us the stop was caused by a software breakpoint, check if
there's a breakpoint instruction in the memory. If so, adjust the
PC before presenting the stop to the user. Otherwise, ignore the
trap. If nothing explains a signal, and the target tells us the
stop was caused by a hardware breakpoint, ignore the trap.

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.

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

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.

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.)

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.)

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.)

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

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.)

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

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

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. It's meant to be a no-op.

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. It's meant to be a no-op.

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

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.)
Regtested on x86-64 Fedora 20.

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.)

This changes instances of TARGET_DEFAULT_RETURN(0) to
TARGET_DEFAULT_RETURN(NULL) when appropriate. The use of "0" was a
relic from an earlier implementation of make-target-delegates; and I
didn't want to go back through the long patch series, fixing up
conflicts, just to change this small detail.

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.)
Regtested on x86-64 Fedora 20.

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.

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.

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.

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.

Simplify target_async hook interface
All callers of target_async pass it the same callback
(inferior_event_handler). Since both common code and target backends
need to be able to put the target in and out of target async mode at
any given time, there's really no way that a different callback could
be passed. This commit simplifies things, and removes the indirection
altogether. Bonus: with this, gdb's target_async method ends up with
the same signature as gdbserver's.

Simplify target_async hook interface
All callers of target_async pass it the same callback
(inferior_event_handler). Since both common code and target backends
need to be able to put the target in and out of target async mode at
any given time, there's really no way that a different callback could
be passed. This commit simplifies things, and removes the indirection
altogether. Bonus: with this, gdb's target_async method ends up with
the same signature as gdbserver's.
Tested on x86_64 Fedora 20, native and gdbserver.

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.

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.)
Regtested on x86-64 Fedora 20.

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.)
Regtested on x86-64 Fedora 20.

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.

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.

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.

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.)
Regtested on x86-64 Fedora 20.

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.)

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.)

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.)

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

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.)

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

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

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

all, I really just wrote it on a whim.
It's not simple to convert every possible method, since a few don't

Printing is done by type, so I introduced some new
debug-printing-specific typedefs to handle cases where it is nicer to

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

lines are printed for entering and existing the outermost call to the
target stack.
For example now you'd see:

<- multi-thread->to_is_async_p (0x1ebb580) = 1
<- multi-thread->to_terminal_ours (0x1ebb580)

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

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.)

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.)

<- 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

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

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.

Teach GDB about targets that can tell whether a trap is a breakpoint event
The moribund locations heuristics are problematic. This patch teaches
GDB about targets that can reliably tell whether a trap was caused by
a software or hardware breakpoint, and thus don't need moribund
locations, thus bypassing all the problems that mechanism has.
The non-stop-fair-events.exp test is frequently failing currently.
E.g., see https://sourceware.org/ml/gdb-testers/2015-q1/msg03148.html.
The root cause is a fundamental problem with moribund locations. For
example, the stepped_breakpoint logic added by af48d08f breaks in this
case (which is what happens with that test):
- Step thread A, no breakpoint is set at PC.
- The kernel doesn't schedule thread A yet.
- Insert breakpoint at A's PC, for some reason (e.g., a step-resume
breakpoint for thread B).
- Kernel finally schedules thread A.
- thread A's stepped_breakpoint flag is not set, even though it now
stepped a breakpoint instruction.
- adjust_pc_after_break gets the PC wrong, because PC == PREV_PC, but
stepped_breakpoint is not set.
We needed the stepped_breakpoint logic to workaround moribund
locations, because otherwise adjust_pc_after_break could apply an
adjustment when it shouldn't just because there _used_ to be a
breakpoint at PC (a moribund breakpoint location). For example, on
x86, that's wrong if the thread really hasn't executed an int3, but
instead executed some other 1-byte long instruction. Getting the PC
adjustment wrong of course leads to the inferior executing the wrong
instruction.
Other problems with moribund locations are:
- if a true SIGTRAP happens to be raised when the program is
executing the PC that used to have a breakpoint, GDB will assume
that is a trap for a breakpoint that has recently been removed, and
thus we miss reporting the random signal to the user.
- to minimize that, we get rid of moribund location after a while.
That while is defined as just a certain number of events being
processed. That number of events sometimes passes by before a
delayed breakpoint is processed, and GDB confuses the trap for a
random signal, thus reporting the random trap. Once the user
resumes the thread, the program crashes because the PC was not
adjusted...
The fix for all this is to bite the bullet and get rid of heuristics
and instead rely on the target knowing accurately what caused the
SIGTRAP. The target/kernel/stub is in the best position to know what
that, because it can e.g. consult priviledged CPU flags GDB has no
access to, or by knowing which exception vector entry was called when
the instruction trapped, etc. Most debug APIs I've seen to date
report breakpoint hits as a distinct event in some fashion. For
example, on the Linux kernel, whether a breakpoint was executed is
exposed to userspace in the si_code field of the SIGTRAP's siginfo.
On Windows, the debug API reports a EXCEPTION_BREAKPOINT exception
code.
We needed to keep around deleted breakpoints in an on-the-side list
(the moribund locations) for two main reasons:
- Know that a SIGTRAP actually is a delayed event for a hit of a
breakpoint that was removed before the event was processed, and
thus should not be reported as a random signal.
- So we still do the decr_pc_after_break adjustment in that case, so
that the thread is resumed at the correct address.
In the new model, if GDB processes an event the target tells is a
breakpoint trap, and GDB doesn't find the corresponding breakpoint in
its breakpoint tables, it means that event is a delayed event for a
breakpoint that has since been removed, and thus the event should be
ignored.
For the decr_pc_after_after issue, it ends up being much simpler that
on targets that can reliably tell whether a breakpoint trapped, for
the breakpoint trap to present the PC already adjusted. Proper
multi-threading support already implies that targets needs to be doing
decr_pc_after_break adjustment themselves, otherwise for example, in
all-stop if two threads hit a breakpoint simultaneously, and the user
does "info threads", he'll see the non-event thread that hit the
breakpoint stopped at the wrong PC.
This way (target adjusts) also ends up eliminating the need for some
awkward re-incrementing of the PC in the record-full and Linux targets
that we do today, and the need for the target_decr_pc_after_break
hook.
If the target always adjusts, then there's a case where GDB needs to
re-increment the PC. Say, on x86, an "int3" instruction that was
explicitly written in the program traps. In this case, GDB should
report a random SIGTRAP signal to the user, with the PC pointing at
the instruction past the int3, just like if GDB was not debugging the
program. The user may well decide to pass the SIGTRAP to the program
because the program being debugged has a SIGTRAP handler that handles
its own breakpoints, and expects the PC to be unadjusted.
Tested on x86-64 Fedora 20.
gdb/ChangeLog:
2015-03-04 Pedro Alves <palves@redhat.com>
* breakpoint.c (need_moribund_for_location_type): New function.
(bpstat_stop_status): Don't skipping checking moribund locations
of breakpoint types which the target tell caused a stop.
(program_breakpoint_here_p): New function, factored out from ...
(bp_loc_is_permanent): ... this.
(update_global_location_list): Don't create a moribund location if
the target supports reporting stops of the type of the removed
breakpoint.
* breakpoint.h (program_breakpoint_here_p): New declaration.
* infrun.c (adjust_pc_after_break): Return early if the target has
already adjusted the PC. Add comments.
(handle_signal_stop): If nothing explains a signal, and the target
tells us the stop was caused by a software breakpoint, check if
there's a breakpoint instruction in the memory. If so, adjust the
PC before presenting the stop to the user. Otherwise, ignore the
trap. If nothing explains a signal, and the target tells us the
stop was caused by a hardware breakpoint, ignore the trap.
* target.h (struct target_ops) <to_stopped_by_sw_breakpoint,
to_supports_stopped_by_sw_breakpoint, to_stopped_by_hw_breakpoint,
to_supports_stopped_by_hw_breakpoint>: New fields.
(target_stopped_by_sw_breakpoint)
(target_supports_stopped_by_sw_breakpoint)
(target_stopped_by_hw_breakpoint)
(target_supports_stopped_by_hw_breakpoint): Define.

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.

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. It's meant to be a no-op.

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.
Built and regtested on x86-64 Fedora 20.

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.

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.

Teach GDB about targets that can tell whether a trap is a breakpoint event
The moribund locations heuristics are problematic. This patch teaches
GDB about targets that can reliably tell whether a trap was caused by
a software or hardware breakpoint, and thus don't need moribund
locations, thus bypassing all the problems that mechanism has.
The non-stop-fair-events.exp test is frequently failing currently.
E.g., see https://sourceware.org/ml/gdb-testers/2015-q1/msg03148.html.
The root cause is a fundamental problem with moribund locations. For
example, the stepped_breakpoint logic added by af48d08f breaks in this
case (which is what happens with that test):
- Step thread A, no breakpoint is set at PC.
- The kernel doesn't schedule thread A yet.
- Insert breakpoint at A's PC, for some reason (e.g., a step-resume
breakpoint for thread B).
- Kernel finally schedules thread A.
- thread A's stepped_breakpoint flag is not set, even though it now
stepped a breakpoint instruction.
- adjust_pc_after_break gets the PC wrong, because PC == PREV_PC, but
stepped_breakpoint is not set.
We needed the stepped_breakpoint logic to workaround moribund
locations, because otherwise adjust_pc_after_break could apply an
adjustment when it shouldn't just because there _used_ to be a
breakpoint at PC (a moribund breakpoint location). For example, on
x86, that's wrong if the thread really hasn't executed an int3, but
instead executed some other 1-byte long instruction. Getting the PC
adjustment wrong of course leads to the inferior executing the wrong
instruction.
Other problems with moribund locations are:
- if a true SIGTRAP happens to be raised when the program is
executing the PC that used to have a breakpoint, GDB will assume
that is a trap for a breakpoint that has recently been removed, and
thus we miss reporting the random signal to the user.
- to minimize that, we get rid of moribund location after a while.
That while is defined as just a certain number of events being
processed. That number of events sometimes passes by before a
delayed breakpoint is processed, and GDB confuses the trap for a
random signal, thus reporting the random trap. Once the user
resumes the thread, the program crashes because the PC was not
adjusted...
The fix for all this is to bite the bullet and get rid of heuristics
and instead rely on the target knowing accurately what caused the
SIGTRAP. The target/kernel/stub is in the best position to know what
that, because it can e.g. consult priviledged CPU flags GDB has no
access to, or by knowing which exception vector entry was called when
the instruction trapped, etc. Most debug APIs I've seen to date
report breakpoint hits as a distinct event in some fashion. For
example, on the Linux kernel, whether a breakpoint was executed is
exposed to userspace in the si_code field of the SIGTRAP's siginfo.
On Windows, the debug API reports a EXCEPTION_BREAKPOINT exception
code.
We needed to keep around deleted breakpoints in an on-the-side list
(the moribund locations) for two main reasons:
- Know that a SIGTRAP actually is a delayed event for a hit of a
breakpoint that was removed before the event was processed, and
thus should not be reported as a random signal.
- So we still do the decr_pc_after_break adjustment in that case, so
that the thread is resumed at the correct address.
In the new model, if GDB processes an event the target tells is a
breakpoint trap, and GDB doesn't find the corresponding breakpoint in
its breakpoint tables, it means that event is a delayed event for a
breakpoint that has since been removed, and thus the event should be
ignored.
For the decr_pc_after_after issue, it ends up being much simpler that
on targets that can reliably tell whether a breakpoint trapped, for
the breakpoint trap to present the PC already adjusted. Proper
multi-threading support already implies that targets needs to be doing
decr_pc_after_break adjustment themselves, otherwise for example, in
all-stop if two threads hit a breakpoint simultaneously, and the user
does "info threads", he'll see the non-event thread that hit the
breakpoint stopped at the wrong PC.
This way (target adjusts) also ends up eliminating the need for some
awkward re-incrementing of the PC in the record-full and Linux targets
that we do today, and the need for the target_decr_pc_after_break
hook.
If the target always adjusts, then there's a case where GDB needs to
re-increment the PC. Say, on x86, an "int3" instruction that was
explicitly written in the program traps. In this case, GDB should
report a random SIGTRAP signal to the user, with the PC pointing at
the instruction past the int3, just like if GDB was not debugging the
program. The user may well decide to pass the SIGTRAP to the program
because the program being debugged has a SIGTRAP handler that handles
its own breakpoints, and expects the PC to be unadjusted.
Tested on x86-64 Fedora 20.

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.

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. It's meant to be a no-op.

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

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.

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.
Built and regtested on x86-64 Fedora 20.

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.

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.

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.)

Teach GDB about targets that can tell whether a trap is a breakpoint event
The moribund locations heuristics are problematic. This patch teaches
GDB about targets that can reliably tell whether a trap was caused by
a software or hardware breakpoint, and thus don't need moribund
locations, thus bypassing all the problems that mechanism has.
The non-stop-fair-events.exp test is frequently failing currently.
E.g., see https://sourceware.org/ml/gdb-testers/2015-q1/msg03148.html.
The root cause is a fundamental problem with moribund locations. For
example, the stepped_breakpoint logic added by af48d08f breaks in this
case (which is what happens with that test):
- Step thread A, no breakpoint is set at PC.
- The kernel doesn't schedule thread A yet.
- Insert breakpoint at A's PC, for some reason (e.g., a step-resume
breakpoint for thread B).
- Kernel finally schedules thread A.
- thread A's stepped_breakpoint flag is not set, even though it now
stepped a breakpoint instruction.
- adjust_pc_after_break gets the PC wrong, because PC == PREV_PC, but
stepped_breakpoint is not set.
We needed the stepped_breakpoint logic to workaround moribund
locations, because otherwise adjust_pc_after_break could apply an
adjustment when it shouldn't just because there _used_ to be a
breakpoint at PC (a moribund breakpoint location). For example, on
x86, that's wrong if the thread really hasn't executed an int3, but
instead executed some other 1-byte long instruction. Getting the PC
adjustment wrong of course leads to the inferior executing the wrong
instruction.
Other problems with moribund locations are:
- if a true SIGTRAP happens to be raised when the program is
executing the PC that used to have a breakpoint, GDB will assume
that is a trap for a breakpoint that has recently been removed, and
thus we miss reporting the random signal to the user.
- to minimize that, we get rid of moribund location after a while.
That while is defined as just a certain number of events being
processed. That number of events sometimes passes by before a
delayed breakpoint is processed, and GDB confuses the trap for a
random signal, thus reporting the random trap. Once the user
resumes the thread, the program crashes because the PC was not
adjusted...
The fix for all this is to bite the bullet and get rid of heuristics
and instead rely on the target knowing accurately what caused the
SIGTRAP. The target/kernel/stub is in the best position to know what
that, because it can e.g. consult priviledged CPU flags GDB has no
access to, or by knowing which exception vector entry was called when
the instruction trapped, etc. Most debug APIs I've seen to date
report breakpoint hits as a distinct event in some fashion. For
example, on the Linux kernel, whether a breakpoint was executed is
exposed to userspace in the si_code field of the SIGTRAP's siginfo.
On Windows, the debug API reports a EXCEPTION_BREAKPOINT exception
code.
We needed to keep around deleted breakpoints in an on-the-side list
(the moribund locations) for two main reasons:
- Know that a SIGTRAP actually is a delayed event for a hit of a
breakpoint that was removed before the event was processed, and
thus should not be reported as a random signal.
- So we still do the decr_pc_after_break adjustment in that case, so
that the thread is resumed at the correct address.
In the new model, if GDB processes an event the target tells is a
breakpoint trap, and GDB doesn't find the corresponding breakpoint in
its breakpoint tables, it means that event is a delayed event for a
breakpoint that has since been removed, and thus the event should be
ignored.
For the decr_pc_after_after issue, it ends up being much simpler that
on targets that can reliably tell whether a breakpoint trapped, for
the breakpoint trap to present the PC already adjusted. Proper
multi-threading support already implies that targets needs to be doing
decr_pc_after_break adjustment themselves, otherwise for example, in
all-stop if two threads hit a breakpoint simultaneously, and the user
does "info threads", he'll see the non-event thread that hit the
breakpoint stopped at the wrong PC.
This way (target adjusts) also ends up eliminating the need for some
awkward re-incrementing of the PC in the record-full and Linux targets
that we do today, and the need for the target_decr_pc_after_break
hook.
If the target always adjusts, then there's a case where GDB needs to
re-increment the PC. Say, on x86, an "int3" instruction that was
explicitly written in the program traps. In this case, GDB should
report a random SIGTRAP signal to the user, with the PC pointing at
the instruction past the int3, just like if GDB was not debugging the
program. The user may well decide to pass the SIGTRAP to the program
because the program being debugged has a SIGTRAP handler that handles
its own breakpoints, and expects the PC to be unadjusted.
Tested on x86-64 Fedora 20.

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. It's meant to be a no-op.

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.)
