remove gdb_string.h
This removes gdb_string.h. This patch is purely mechanical. I
created it by running the two commands:

Allow making GDB not automatically connect to the native target.
Sometimes it's useful to be able to disable the automatic connection
to the native target. E.g., sometimes GDB disconnects from the
extended-remote target I was debugging, without me noticing it, and
then I do "run". That starts the program locally, and only after a
little head scratch session do I figure out the program is running
locally instead of remotely as intended. Same thing with "attach",
"info os", etc.
With the patch, we now can have this instead:
(gdb) set auto-connect-native-target off
(gdb) target extended-remote :9999
...
*gdb disconnects*
(gdb) run
Don't know how to run. Try "help target".
To still be able to connect to the native target with
auto-connect-native-target set to off, I've made "target native" work
instead of erroring out as today.
Before:
(gdb) target native
Use the "run" command to start a native process.
After:
(gdb) target native
Done. Use the "run" command to start a process.
(gdb) maint print target-stack
The current target stack is:
- native (Native process)
- exec (Local exec file)
- None (None)
(gdb) run
Starting program: ./a.out
...
I've also wanted this for the testsuite, when running against the
native-extended-gdbserver.exp board (runs against gdbserver in
extended-remote mode). With a non-native-target board, it's always a
bug to launch a program with the native target. Turns out we still
have one such case this patch catches:
(gdb) break main
Breakpoint 1 at 0x4009e5: file ../../../src/gdb/testsuite/gdb.base/coremaker.c, line 138.
(gdb) run
Don't know how to run. Try "help target".
(gdb) FAIL: gdb.base/corefile.exp: run: with core
On the patch itself, probably the least obvious bit is the need to go
through all targets, and move the unpush_target call to after the
generic_mourn_inferior call instead of before. This is what
inf-ptrace.c does too, ever since multi-process support was added.
The reason inf-ptrace.c does things in that order is that in the
current multi-process/single-target model, we shouldn't unpush the
target if there are still other live inferiors being debugged. The
check for that is "have_inferiors ()" (a misnomer nowadays...), which
does:
have_inferiors (void)
{
for (inf = inferior_list; inf; inf = inf->next)
if (inf->pid != 0)
return 1;
It's generic_mourn_inferior that ends up clearing inf->pid, so we need
to call it before the have_inferiors check. To make all native
targets behave the same WRT to explicit "target native", I've added an
inf_child_maybe_unpush_target function that targets call instead of
calling unpush_target directly, and as that includes the
have_inferiors check, I needed to adjust the targets.
Tested on x86_64 Fedora 20, native, and also with the
extended-gdbserver board.
Confirmed a cross build of djgpp gdb still builds.
Smoke tested a cross build of Windows gdb under Wine.
Untested otherwise.

Allow making GDB not automatically connect to the native target.
Sometimes it's useful to be able to disable the automatic connection
to the native target. E.g., sometimes GDB disconnects from the
extended-remote target I was debugging, without me noticing it, and
then I do "run". That starts the program locally, and only after a
little head scratch session do I figure out the program is running
locally instead of remotely as intended. Same thing with "attach",
"info os", etc.
With the patch, we now can have this instead:
(gdb) set auto-connect-native-target off
(gdb) target extended-remote :9999
...
*gdb disconnects*
(gdb) run
Don't know how to run. Try "help target".
To still be able to connect to the native target with
auto-connect-native-target set to off, I've made "target native" work
instead of erroring out as today.
Before:
(gdb) target native
Use the "run" command to start a native process.
After:
(gdb) target native
Done. Use the "run" command to start a process.
(gdb) maint print target-stack
The current target stack is:
- native (Native process)
- exec (Local exec file)
- None (None)
(gdb) run
Starting program: ./a.out
...
I've also wanted this for the testsuite, when running against the
native-extended-gdbserver.exp board (runs against gdbserver in
extended-remote mode). With a non-native-target board, it's always a
bug to launch a program with the native target. Turns out we still
have one such case this patch catches:
(gdb) break main
Breakpoint 1 at 0x4009e5: file ../../../src/gdb/testsuite/gdb.base/coremaker.c, line 138.
(gdb) run
Don't know how to run. Try "help target".
(gdb) FAIL: gdb.base/corefile.exp: run: with core
On the patch itself, probably the least obvious bit is the need to go
through all targets, and move the unpush_target call to after the
generic_mourn_inferior call instead of before. This is what
inf-ptrace.c does too, ever since multi-process support was added.
The reason inf-ptrace.c does things in that order is that in the
current multi-process/single-target model, we shouldn't unpush the
target if there are still other live inferiors being debugged. The
check for that is "have_inferiors ()" (a misnomer nowadays...), which
does:
have_inferiors (void)
{
for (inf = inferior_list; inf; inf = inf->next)
if (inf->pid != 0)
return 1;
It's generic_mourn_inferior that ends up clearing inf->pid, so we need
to call it before the have_inferiors check. To make all native
targets behave the same WRT to explicit "target native", I've added an
inf_child_maybe_unpush_target function that targets call instead of
calling unpush_target directly, and as that includes the
have_inferiors check, I needed to adjust the targets.
Tested on x86_64 Fedora 20, native, and also with the
extended-gdbserver board.
Confirmed a cross build of djgpp gdb still builds.
Smoke tested a cross build of Windows gdb under Wine.
Untested otherwise.

constify to_open
This makes target_ops::to_open take a const string and then fixes the
fallout.
There were a few of these I could not build. However I eyeballed it
and in any case the fixes should generally be trivial.
This is based on the patch to fix up the target debugging for to_open,
because that changes gdb to not directly install to_open as the target
command

little head scratch session do I figure out the program is running
locally instead of remotely as intended. Same thing with "attach",
"info os", etc.
With the patch, we now can have this instead:
(gdb) set auto-connect-native-target off
(gdb) target extended-remote :9999
...
*gdb disconnects*
(gdb) run
Don't know how to run. Try "help target".
To still be able to connect to the native target with
auto-connect-native-target set to off, I've made "target native" work
instead of erroring out as today.
Before:
(gdb) target native
Use the "run" command to start a native process.
After:
(gdb) target native
Done. Use the "run" command to start a process.
(gdb) maint print target-stack
The current target stack is:
- native (Native process)
- exec (Local exec file)
- None (None)
(gdb) run
Starting program: ./a.out
...
I've also wanted this for the testsuite, when running against the
native-extended-gdbserver.exp board (runs against gdbserver in
extended-remote mode). With a non-native-target board, it's always a
bug to launch a program with the native target. Turns out we still
have one such case this patch catches:
(gdb) break main
Breakpoint 1 at 0x4009e5: file ../../../src/gdb/testsuite/gdb.base/coremaker.c, line 138.
(gdb) run
Don't know how to run. Try "help target".
(gdb) FAIL: gdb.base/corefile.exp: run: with core
On the patch itself, probably the least obvious bit is the need to go
through all targets, and move the unpush_target call to after the
generic_mourn_inferior call instead of before. This is what
inf-ptrace.c does too, ever since multi-process support was added.
The reason inf-ptrace.c does things in that order is that in the
current multi-process/single-target model, we shouldn't unpush the
target if there are still other live inferiors being debugged. The
check for that is "have_inferiors ()" (a misnomer nowadays...), which
does:
have_inferiors (void)
{
for (inf = inferior_list; inf; inf = inf->next)
if (inf->pid != 0)
return 1;
It's generic_mourn_inferior that ends up clearing inf->pid, so we need
to call it before the have_inferiors check. To make all native
targets behave the same WRT to explicit "target native", I've added an
inf_child_maybe_unpush_target function that targets call instead of
calling unpush_target directly, and as that includes the
have_inferiors check, I needed to adjust the targets.
Tested on x86_64 Fedora 20, native, and also with the
extended-gdbserver board.
Confirmed a cross build of djgpp gdb still builds.
Smoke tested a cross build of Windows gdb under Wine.
Untested otherwise.

Allow making GDB not automatically connect to the native target.

to the native target. E.g., sometimes GDB disconnects from the
extended-remote target I was debugging, without me noticing it, and

locally instead of remotely as intended. Same thing with "attach",

auto-connect-native-target set to off, I've made "target native" work
instead of erroring out as today.

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.

Allow making GDB not automatically connect to the native target.
Sometimes it's useful to be able to disable the automatic connection
to the native target. E.g., sometimes GDB disconnects from the
extended-remote target I was debugging, without me noticing it, and
then I do "run". That starts the program locally, and only after a
little head scratch session do I figure out the program is running
locally instead of remotely as intended. Same thing with "attach",
"info os", etc.
With the patch, we now can have this instead:
(gdb) set auto-connect-native-target off
(gdb) target extended-remote :9999
...
*gdb disconnects*
(gdb) run
Don't know how to run. Try "help target".
To still be able to connect to the native target with
auto-connect-native-target set to off, I've made "target native" work
instead of erroring out as today.
Before:
(gdb) target native
Use the "run" command to start a native process.
After:
(gdb) target native
Done. Use the "run" command to start a process.
(gdb) maint print target-stack
The current target stack is:
- native (Native process)
- exec (Local exec file)
- None (None)
(gdb) run
Starting program: ./a.out
...
I've also wanted this for the testsuite, when running against the
native-extended-gdbserver.exp board (runs against gdbserver in
extended-remote mode). With a non-native-target board, it's always a
bug to launch a program with the native target. Turns out we still
have one such case this patch catches:
(gdb) break main
Breakpoint 1 at 0x4009e5: file ../../../src/gdb/testsuite/gdb.base/coremaker.c, line 138.
(gdb) run
Don't know how to run. Try "help target".
(gdb) FAIL: gdb.base/corefile.exp: run: with core
On the patch itself, probably the least obvious bit is the need to go
through all targets, and move the unpush_target call to after the
generic_mourn_inferior call instead of before. This is what
inf-ptrace.c does too, ever since multi-process support was added.
The reason inf-ptrace.c does things in that order is that in the
current multi-process/single-target model, we shouldn't unpush the
target if there are still other live inferiors being debugged. The
check for that is "have_inferiors ()" (a misnomer nowadays...), which
does:
have_inferiors (void)
{
for (inf = inferior_list; inf; inf = inf->next)
if (inf->pid != 0)
return 1;
It's generic_mourn_inferior that ends up clearing inf->pid, so we need
to call it before the have_inferiors check. To make all native
targets behave the same WRT to explicit "target native", I've added an
inf_child_maybe_unpush_target function that targets call instead of
calling unpush_target directly, and as that includes the
have_inferiors check, I needed to adjust the targets.
Tested on x86_64 Fedora 20, native, and also with the
extended-gdbserver board.
Confirmed a cross build of djgpp gdb still builds.
Smoke tested a cross build of Windows gdb under Wine.
Untested otherwise.

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.

Allow making GDB not automatically connect to the native target.
Sometimes it's useful to be able to disable the automatic connection
to the native target. E.g., sometimes GDB disconnects from the
extended-remote target I was debugging, without me noticing it, and
then I do "run". That starts the program locally, and only after a
little head scratch session do I figure out the program is running
locally instead of remotely as intended. Same thing with "attach",
"info os", etc.
With the patch, we now can have this instead:
(gdb) set auto-connect-native-target off
(gdb) target extended-remote :9999
...
*gdb disconnects*
(gdb) run
Don't know how to run. Try "help target".
To still be able to connect to the native target with
auto-connect-native-target set to off, I've made "target native" work
instead of erroring out as today.
Before:
(gdb) target native
Use the "run" command to start a native process.
After:
(gdb) target native
Done. Use the "run" command to start a process.
(gdb) maint print target-stack
The current target stack is:
- native (Native process)
- exec (Local exec file)
- None (None)
(gdb) run
Starting program: ./a.out
...
I've also wanted this for the testsuite, when running against the
native-extended-gdbserver.exp board (runs against gdbserver in
extended-remote mode). With a non-native-target board, it's always a
bug to launch a program with the native target. Turns out we still
have one such case this patch catches:
(gdb) break main
Breakpoint 1 at 0x4009e5: file ../../../src/gdb/testsuite/gdb.base/coremaker.c, line 138.
(gdb) run
Don't know how to run. Try "help target".
(gdb) FAIL: gdb.base/corefile.exp: run: with core
On the patch itself, probably the least obvious bit is the need to go
through all targets, and move the unpush_target call to after the
generic_mourn_inferior call instead of before. This is what
inf-ptrace.c does too, ever since multi-process support was added.
The reason inf-ptrace.c does things in that order is that in the
current multi-process/single-target model, we shouldn't unpush the
target if there are still other live inferiors being debugged. The
check for that is "have_inferiors ()" (a misnomer nowadays...), which
does:
have_inferiors (void)
{
for (inf = inferior_list; inf; inf = inf->next)
if (inf->pid != 0)
return 1;
It's generic_mourn_inferior that ends up clearing inf->pid, so we need
to call it before the have_inferiors check. To make all native
targets behave the same WRT to explicit "target native", I've added an
inf_child_maybe_unpush_target function that targets call instead of
calling unpush_target directly, and as that includes the
have_inferiors check, I needed to adjust the targets.
Tested on x86_64 Fedora 20, native, and also with the
extended-gdbserver board.
Confirmed a cross build of djgpp gdb still builds.
Smoke tested a cross build of Windows gdb under Wine.
Untested otherwise.
