Add new infrun.h header.
Move infrun.c declarations out of inferior.h to a new infrun.h file.
Tested by building on:
i686-w64-mingw32, enable-targets=all
x86_64-linux, enable-targets=all
i586-pc-msdosdjgpp
And also grepped the whole tree for each symbol moved to find where
infrun.h might be necessary.

/* This module provides the interface between GDB and the
|
|
|
|
/proc file system, which is used on many versions of Unix
|
|
|
|
as a means for debuggers to control other processes.
|
|
|
|
|
|
|
|
Examples of the systems that use this interface are:
|
|
|
|
|
|
|
|
Irix
|
|
|
|
Solaris
|
|
|
|
OSF
|
|
|
|
AIX5
|
|
|
|
|
|
|
|
/proc works by imitating a file system: you open a simulated file
|
|
|
|
that represents the process you wish to interact with, and perform
|
|
|
|
operations on that "file" in order to examine or change the state
|
|
|
|
of the other process.
|
|
|
|
|
|
|
|
The most important thing to know about /proc and this module is
|
|
|
|
that there are two very different interfaces to /proc:
|
|
|
|
|
|
|
|
One that uses the ioctl system call, and another that uses read
|
|
|
|
and write system calls.
|
|
|
|
|
|
|
|
This module has to support both /proc interfaces. This means that
|
|
|
|
there are two different ways of doing every basic operation.
|
|
|
|
|
|
|
|
In order to keep most of the code simple and clean, I have defined
|
|
|
|
an interface "layer" which hides all these system calls. An ifdef
|
|
|
|
(NEW_PROC_API) determines which interface we are using, and most or
|
|
|
|
all occurrances of this ifdef should be confined to this interface
|
|
|
|
layer. */
|
|
|
|
|
|
|
|
/* Determine which /proc API we are using: The ioctl API defines
|
|
|
|
PIOCSTATUS, while the read/write (multiple fd) API never does. */

constify to_detach
This patch constifies the target_ops method to_detach.
This is a small cleanup, but also, I think, a bug-prevention fix,
since gdb already acts as if the "args" argument here was const.
In particular, top.c:quit_force calls kill_or_detach via
iterate_over_inferiors. kill_or_detach calls target_detach, passing
the same argument each time. So, if one of these methods was not
const-correct, then kill_or_detach would change its behavior in a
strange way.
I could not build every target I modified in this patch. I've
inspected them all by hand, though. Many targets do not use the
"args" parameter; a couple pass it to atoi; and a few pass it on to
the to_detach method of the target beneath. The only code that
required a real change was in linux-nat.c, and that only needed the
introduction of a temporary variable for const-correctness.

Fix interrupt-noterm.exp on targets always in non-stop

+testcase src/gdb/testsuite/gdb.base/interrupt-noterm.exp completed in 10 seconds
That is, we get "[$thread] #1 stopped" instead of SIGINT.
The issue is that we don't currently distinguish send
"interrupt/ctrl-c" to target terminal vs "stop/pause" thread well;
both cases go through "target_stop".
And then, the native Linux backend (linux-nat.c) implements
target_stop with SIGSTOP in non-stop mode, and SIGINT in all-stop
mode. Since "maint set target-non-stop on" forces the backend to be
always running in non-stop mode, even though the user-visible behavior
is "set non-stop" is "off", "interrupt" causes a SIGSTOP instead of
the SIGINT the test expects.
Fix this by introducing a target_interrupt method to use in the
"interrupt/ctrl-c" case, so "set non-stop off" can always work the
same irrespective of "maint set target-non-stop on/off". I'm
explictly considering changing the "set non-stop on" behavior as out
of scope here.
Most of the patch is an across-the-board rename of to_stop hook
implementations to to_interrupt. The only targets where something
more than a rename is being done are linux-nat.c and remote.c, which
are the only targets that support async, and thus are the only ones
the core side calls target_stop on.

Fix gdb procfs.c compilation on Solaris
Prompted by the creation of the gdb 8.0 branch, I tried to build it on
x86_64-pc-solaris2.12, but failed:
/vol/src/gnu/gdb/gdb-8.0-branch/local/gdb/procfs.c: In function `target_ops* procfs_target()':

Push pruning old threads down to the target
When GDB wants to sync the thread list with the target's (e.g., due to
"info threads"), it calls update_thread_list:
update_thread_list (void)
{
prune_threads ();
target_find_new_threads ();
update_threads_executing ();
}
And then prune_threads does:
prune_threads (void)
{
struct thread_info *tp, *next;
for (tp = thread_list; tp; tp = next)
{
next = tp->next;
if (!thread_alive (tp))
delete_thread (tp->ptid);
}
}
Calling thread_live on each thread one by one is expensive.
E.g., on Linux, it ends up doing kill(SIG0) once for each thread. Not
a big deal, but still a bunch of syscalls...
With the remote target, it's cumbersome. That thread_alive call ends
up generating one T packet per thread:
Sending packet: $Tp2141.2150#82...Packet received: OK
Sending packet: $Tp2141.214f#b7...Packet received: OK
Sending packet: $Tp2141.2141#82...Packet received: OK
Sending packet: $qXfer:threads:read::0,fff#03...Packet received: l<threads>\n<thread id="p2141.2141" core="2"/>\n<thread id="p2141.214f" core="1"/>\n<thread id="p2141.2150" core="2"/>\n</threads>\n
That seems a bit silly when target_find_new_threads method
implementations will always fetch the whole current set of target
threads, and then add those that are not in GDB's thread list, to
GDB's thread list.
This patch thus pushes down the responsibility of pruning dead threads
to the target_find_new_threads method instead, so a target may
implement pruning dead threads however it wants.
Once we do that, target_find_new_threads becomes a misnomer, so the
patch renames it to target_update_thread_list.
The patch doesn't attempt to do any optimization to any target yet.
It simply exports prune_threads, and makes all implementations of
target_update_thread_list call that. It's meant to be a no-op.

Fix interrupt-noterm.exp on targets always in non-stop

+testcase src/gdb/testsuite/gdb.base/interrupt-noterm.exp completed in 10 seconds
That is, we get "[$thread] #1 stopped" instead of SIGINT.
The issue is that we don't currently distinguish send
"interrupt/ctrl-c" to target terminal vs "stop/pause" thread well;
both cases go through "target_stop".
And then, the native Linux backend (linux-nat.c) implements
target_stop with SIGSTOP in non-stop mode, and SIGINT in all-stop
mode. Since "maint set target-non-stop on" forces the backend to be
always running in non-stop mode, even though the user-visible behavior
is "set non-stop" is "off", "interrupt" causes a SIGSTOP instead of
the SIGINT the test expects.
Fix this by introducing a target_interrupt method to use in the
"interrupt/ctrl-c" case, so "set non-stop off" can always work the
same irrespective of "maint set target-non-stop on/off". I'm
explictly considering changing the "set non-stop on" behavior as out
of scope here.
Most of the patch is an across-the-board rename of to_stop hook
implementations to to_interrupt. The only targets where something
more than a rename is being done are linux-nat.c and remote.c, which
are the only targets that support async, and thus are the only ones
the core side calls target_stop on.

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.

procfs.c: iterate_over_mappings callback has wrong profile.
The function proc_find_memory_regions calls iterate_over_mappings as
follow:
> return iterate_over_mappings (pi, func, data,
> find_memory_regions_callback);
The problem is that both func and find_memory_regions_callback
do not match the profile expected by iterate_over_mappings:
> iterate_over_mappings (procinfo *pi, int (*child_func) (), void *data,
> int (*func) (struct prmap *map,
> int (*child_func) (),
> void *data))
We cannot change proc_find_memory_regions such that FUNC is a pointer
to a function that takes no argument (in place of the 6 that it has).
This is because proc_find_memory_regions is used as a target_ops method.
However, it turns out that changing iterate_over_mappings to conform
to the profile imposed by the target_ops vector is possible without
much effort.
gdb/ChangeLog:
* procfs.c (iterate_over_mappings_cb_ftype): New typedef.
(iterate_over_mappings): Adjust function profile. Add declaration.
(insert_dbx_link_bpt_in_region, info_mappings_callback):
Adjust accordingly.

The problem is that both func and find_memory_regions_callback
do not match the profile expected by iterate_over_mappings:
> iterate_over_mappings (procinfo *pi, int (*child_func) (), void *data,
> int (*func) (struct prmap *map,
> int (*child_func) (),
> void *data))
We cannot change proc_find_memory_regions such that FUNC is a pointer
to a function that takes no argument (in place of the 6 that it has).
This is because proc_find_memory_regions is used as a target_ops method.
However, it turns out that changing iterate_over_mappings to conform
to the profile imposed by the target_ops vector is possible without
much effort.
gdb/ChangeLog:
* procfs.c (iterate_over_mappings_cb_ftype): New typedef.
(iterate_over_mappings): Adjust function profile. Add declaration.
(insert_dbx_link_bpt_in_region, info_mappings_callback):
Adjust accordingly.

2012-12-11 12:32:39 +01:00
|
|
|
NEW_PROC_API (Solaris 2.6, Solaris 2.7):
|
2010-05-17 12:42:27 +02:00
|
|
|
There are several file descriptors that may need to be open
|
|
|
|
for any given process or LWP. The ones we're intereted in are:
|
|
|
|
- control (ctl) write-only change the state
|
|
|
|
- status (status) read-only query the state
|
|
|
|
- address space (as) read/write access memory
|
|
|
|
- map (map) read-only virtual addr map
|
|
|
|
Most of these are opened lazily as they are needed.
|
|
|
|
The pathnames for the 'files' for an LWP look slightly
|
|
|
|
different from those of a first-class process:
|
|
|
|
Pathnames for a process (<proc-id>):
|
|
|
|
/proc/<proc-id>/ctl
|
|
|
|
/proc/<proc-id>/status
|
|
|
|
/proc/<proc-id>/as
|
|
|
|
/proc/<proc-id>/map
|
|
|
|
Pathnames for an LWP (lwp-id):
|
|
|
|
/proc/<proc-id>/lwp/<lwp-id>/lwpctl
|
|
|
|
/proc/<proc-id>/lwp/<lwp-id>/lwpstatus
|
|
|
|
An LWP has no map or address space file descriptor, since
|
|
|
|
the memory map and address space are shared by all LWPs.
|
|
|
|
|
|
|
|
Everyone else (Solaris 2.5, Irix, OSF)
|
|
|
|
There is only one file descriptor for each process or LWP.
|
|
|
|
For convenience, we copy the same file descriptor into all
|
|
|
|
three fields of the procinfo struct (ctl_fd, status_fd, and
|
|
|
|
as_fd, see NEW_PROC_API above) so that code that uses them
|
|
|
|
doesn't need any #ifdef's.
|
|
|
|
Pathname for all:
|
|
|
|
/proc/<proc-id>
|
|
|
|
|
|
|
|
Solaris 2.5 LWP's:
|
|
|
|
Each LWP has an independent file descriptor, but these
|
|
|
|
are not obtained via the 'open' system call like the rest:
|
|
|
|
instead, they're obtained thru an ioctl call (PIOCOPENLWP)
|
|
|
|
to the file descriptor of the parent process.
|
|
|
|
|
|
|
|
OSF threads:
|
|
|
|
These do not even have their own independent file descriptor.
|
|
|
|
All operations are carried out on the file descriptor of the
|
|
|
|
parent process. Therefore we just call open again for each
|
2011-01-10 21:38:51 +01:00
|
|
|
thread, getting a new handle for the same 'file'. */

Replace some xmalloc-family functions with XNEW-family ones
This patch is part of the make-gdb-buildable-in-C++ effort. The idea is
to change some calls to the xmalloc family of functions to calls to the
equivalents in the XNEW family. This avoids adding an explicit cast, so
it keeps the code a bit more readable. Some of them also map relatively
well to a C++ equivalent (XNEW (struct foo) -> new foo), so it will be
possible to do scripted replacements if needed.
I only changed calls that were obviously allocating memory for one or
multiple "objects". Allocation of variable sizes (such as strings or
buffer handling) will be for later (and won't use XNEW).
- xmalloc (sizeof (struct foo)) -> XNEW (struct foo)
- xmalloc (num * sizeof (struct foo)) -> XNEWVEC (struct foo, num)
- xcalloc (1, sizeof (struct foo)) -> XCNEW (struct foo)
- xcalloc (num, sizeof (struct foo)) -> XCNEWVEC (struct foo, num)
- xrealloc (p, num * sizeof (struct foo) -> XRESIZEVEC (struct foo, p, num)
- obstack_alloc (ob, sizeof (struct foo)) -> XOBNEW (ob, struct foo)
- obstack_alloc (ob, num * sizeof (struct foo)) -> XOBNEWVEC (ob, struct foo, num)
- alloca (sizeof (struct foo)) -> XALLOCA (struct foo)
- alloca (num * sizeof (struct foo)) -> XALLOCAVEC (struct foo, num)
Some instances of xmalloc followed by memset to zero the buffer were
replaced by XCNEW or XCNEWVEC.
I regtested on x86-64, Ubuntu 14.04, but the patch touches many
architecture-specific files. For those I'll have to rely on the
buildbot or people complaining that I broke their gdb.

Fix gdb C++ compilation on Solaris (PR build/20712)
gdb 7.12 doesn't compile as C++ (tried with g++ 4.9) on Solaris (tried
10 and 12, sparc and x86). The following patch (relative to the 7.12
release, though I expect most if not all issues to be present on trunk,
too) fixes this.
Only a few of the changes bear explanation:
* Initially, compilation failed whereever defs.h. was included:

extern double atof(const char *);

This is due to this gem in gdb/defs.h which seems to have been present
like forever:
#ifndef atof
extern double atof (const char *); /* X3.159-1989 4.10.1.1 */
#endif
In the Solaris headers, the appropriate functions are in namespace std,
thus the conflict. I've wrapped the defs.h declaration in !__cplusplus
to avoid this; perhaps it can go completely instead.
* All the casts are necessary to appease g++ and should be pretty
obvious.
* The sol-thread.c changes are here to handle
/vol/src/gnu/gdb/gdb-7.12/gdb/sol-thread.c: In function 'void _initialize_sol_thread()':

^
and are modeled after linux-thread-db.c (try_thread_db_load_1).
The patch allowed both 32 and 64-bit C++ builds on sparc-sun-solaris2.10
and i386-pc-solaris2.10 to complete. The resulting binary hasn't seen
more than a smoke test (invoke it on itself, b main, run) yet.
When investigating the failure to detect -static-libstdc++
support (more below), I found two more issues which only show up with

Replace some xmalloc-family functions with XNEW-family ones
This patch is part of the make-gdb-buildable-in-C++ effort. The idea is
to change some calls to the xmalloc family of functions to calls to the
equivalents in the XNEW family. This avoids adding an explicit cast, so
it keeps the code a bit more readable. Some of them also map relatively
well to a C++ equivalent (XNEW (struct foo) -> new foo), so it will be
possible to do scripted replacements if needed.
I only changed calls that were obviously allocating memory for one or
multiple "objects". Allocation of variable sizes (such as strings or
buffer handling) will be for later (and won't use XNEW).
- xmalloc (sizeof (struct foo)) -> XNEW (struct foo)
- xmalloc (num * sizeof (struct foo)) -> XNEWVEC (struct foo, num)
- xcalloc (1, sizeof (struct foo)) -> XCNEW (struct foo)
- xcalloc (num, sizeof (struct foo)) -> XCNEWVEC (struct foo, num)
- xrealloc (p, num * sizeof (struct foo) -> XRESIZEVEC (struct foo, p, num)
- obstack_alloc (ob, sizeof (struct foo)) -> XOBNEW (ob, struct foo)
- obstack_alloc (ob, num * sizeof (struct foo)) -> XOBNEWVEC (ob, struct foo, num)
- alloca (sizeof (struct foo)) -> XALLOCA (struct foo)
- alloca (num * sizeof (struct foo)) -> XALLOCAVEC (struct foo, num)
Some instances of xmalloc followed by memset to zero the buffer were
replaced by XCNEW or XCNEWVEC.
I regtested on x86-64, Ubuntu 14.04, but the patch touches many
architecture-specific files. For those I'll have to rely on the
buildbot or people complaining that I broke their gdb.

=== This is an area where the different versions of

|
|
|
|
|
|
|
|
Set or reset any of the following process flags:
|
|
|
|
PR_FORK -- forked child will inherit trace flags
|
|
|
|
PR_RLC -- traced process runs when last /proc file closed.
|
|
|
|
PR_KLC -- traced process is killed when last /proc file closed.
|
|
|
|
PR_ASYNC -- LWP's get to run/stop independently.
|
|
|
|
|
|
|
|
There are three methods for doing this function:
|
|
|
|
1) Newest: read/write [PCSET/PCRESET/PCUNSET]
|
|
|
|
[Sol6, Sol7, UW]
|
|
|
|
2) Middle: PIOCSET/PIOCRESET
|
|
|
|
[Irix, Sol5]
|
|
|
|
3) Oldest: PIOCSFORK/PIOCRFORK/PIOCSRLC/PIOCRRLC
|
|
|
|
[OSF, Sol5]
|
|
|
|
|
|
|
|
Note: Irix does not define PR_ASYNC.
|
|
|
|
Note: OSF does not define PR_KLC.
|
|
|
|
Note: OSF is the only one that can ONLY use the oldest method.
|
|
|
|
|
|
|
|
Arguments:
|
|
|
|
pi -- the procinfo
|
|
|
|
flag -- one of PR_FORK, PR_RLC, or PR_ASYNC
|
|
|
|
mode -- 1 for set, 0 for reset.
|
|
|
|
|
|

Fix gdb C++ compilation on Solaris (PR build/20712)
gdb 7.12 doesn't compile as C++ (tried with g++ 4.9) on Solaris (tried
10 and 12, sparc and x86). The following patch (relative to the 7.12
release, though I expect most if not all issues to be present on trunk,
too) fixes this.
Only a few of the changes bear explanation:
* Initially, compilation failed whereever defs.h. was included:
In file included from /vol/src/gnu/gdb/gdb-7.12/gdb/gdb.c:19:0:
/vol/src/gnu/gdb/gdb-7.12/gdb/defs.h:630:33: error: 'double atof(const char*)' conflicts with a previous declaration

^
In file included from /usr/include/stdlib.h:17:0,

extern double atof(const char *);
^
This is due to this gem in gdb/defs.h which seems to have been present
like forever:
#ifndef atof
extern double atof (const char *); /* X3.159-1989 4.10.1.1 */
#endif
In the Solaris headers, the appropriate functions are in namespace std,
thus the conflict. I've wrapped the defs.h declaration in !__cplusplus
to avoid this; perhaps it can go completely instead.
* All the casts are necessary to appease g++ and should be pretty
obvious.
* The sol-thread.c changes are here to handle
/vol/src/gnu/gdb/gdb-7.12/gdb/sol-thread.c: In function 'void _initialize_sol_thread()':
/vol/src/gnu/gdb/gdb-7.12/gdb/sol-thread.c:1252:36: error: invalid conversion from 'void*' to 'void (*)(int)' [-fpermissive]

resolve (td_log);
^
and are modeled after linux-thread-db.c (try_thread_db_load_1).
The patch allowed both 32 and 64-bit C++ builds on sparc-sun-solaris2.10
and i386-pc-solaris2.10 to complete. The resulting binary hasn't seen
more than a smoke test (invoke it on itself, b main, run) yet.
When investigating the failure to detect -static-libstdc++
support (more below), I found two more issues which only show up with
-Werror:
/vol/src/gnu/gdb/gdb/local/gdb/procfs.c: In function 'ssd* proc_get_LDT_entry(procinfo*, int)':
/vol/src/gnu/gdb/gdb/local/gdb/procfs.c:2487:19: error: variable 'old_chain' set but not used [-Werror=unused-but-set-variable]
struct cleanup *old_chain = NULL;
^
Unless I'm mistaken, you need to run do_cleanups on every return from
the function.
Afterwards, I ran a 32-bit compilation, which (after adding
--disable-largefile to avoid
In file included from /usr/include/sys/procfs.h:28:0,
from /vol/src/gnu/gdb/gdb/local/gdb/i386-sol2-nat.c:23:

#error "Cannot use procfs in the large file compilation environment"

and two more instances) revealed
/vol/src/gnu/gdb/gdb/local/gdb/top.c: In function 'void gdb_safe_append_history()':

^
Fixed by casting pid_t to long and printing it as such.

Fix gdb C++ compilation on Solaris (PR build/20712)
gdb 7.12 doesn't compile as C++ (tried with g++ 4.9) on Solaris (tried
10 and 12, sparc and x86). The following patch (relative to the 7.12
release, though I expect most if not all issues to be present on trunk,
too) fixes this.
Only a few of the changes bear explanation:
* Initially, compilation failed whereever defs.h. was included:
In file included from /vol/src/gnu/gdb/gdb-7.12/gdb/gdb.c:19:0:
/vol/src/gnu/gdb/gdb-7.12/gdb/defs.h:630:33: error: 'double atof(const char*)' conflicts with a previous declaration
extern double atof (const char *); /* X3.159-1989 4.10.1.1 */
^
In file included from /usr/include/stdlib.h:17:0,

extern double atof(const char *);
^
This is due to this gem in gdb/defs.h which seems to have been present
like forever:
#ifndef atof
extern double atof (const char *); /* X3.159-1989 4.10.1.1 */
#endif
In the Solaris headers, the appropriate functions are in namespace std,
thus the conflict. I've wrapped the defs.h declaration in !__cplusplus
to avoid this; perhaps it can go completely instead.
* All the casts are necessary to appease g++ and should be pretty
obvious.
* The sol-thread.c changes are here to handle
/vol/src/gnu/gdb/gdb-7.12/gdb/sol-thread.c: In function 'void _initialize_sol_thread()':
/vol/src/gnu/gdb/gdb-7.12/gdb/sol-thread.c:1252:36: error: invalid conversion from 'void*' to 'void (*)(int)' [-fpermissive]

resolve (td_log);
^
and are modeled after linux-thread-db.c (try_thread_db_load_1).
The patch allowed both 32 and 64-bit C++ builds on sparc-sun-solaris2.10
and i386-pc-solaris2.10 to complete. The resulting binary hasn't seen
more than a smoke test (invoke it on itself, b main, run) yet.
When investigating the failure to detect -static-libstdc++
support (more below), I found two more issues which only show up with
-Werror:
/vol/src/gnu/gdb/gdb/local/gdb/procfs.c: In function 'ssd* proc_get_LDT_entry(procinfo*, int)':
/vol/src/gnu/gdb/gdb/local/gdb/procfs.c:2487:19: error: variable 'old_chain' set but not used [-Werror=unused-but-set-variable]
struct cleanup *old_chain = NULL;
^
Unless I'm mistaken, you need to run do_cleanups on every return from
the function.
Afterwards, I ran a 32-bit compilation, which (after adding
--disable-largefile to avoid
In file included from /usr/include/sys/procfs.h:28:0,
from /vol/src/gnu/gdb/gdb/local/gdb/i386-sol2-nat.c:23:

#error "Cannot use procfs in the large file compilation environment"

and two more instances) revealed
/vol/src/gnu/gdb/gdb/local/gdb/top.c: In function 'void gdb_safe_append_history()':
/vol/src/gnu/gdb/gdb/local/gdb/top.c:1170:59: error: format '%d' expects argument of type 'int', but argument 3 has type 'pid_t {aka long int}' [-Werror=format=]

^
Fixed by casting pid_t to long and printing it as such.

Replace some xmalloc-family functions with XNEW-family ones
This patch is part of the make-gdb-buildable-in-C++ effort. The idea is
to change some calls to the xmalloc family of functions to calls to the
equivalents in the XNEW family. This avoids adding an explicit cast, so
it keeps the code a bit more readable. Some of them also map relatively
well to a C++ equivalent (XNEW (struct foo) -> new foo), so it will be
possible to do scripted replacements if needed.
I only changed calls that were obviously allocating memory for one or
multiple "objects". Allocation of variable sizes (such as strings or
buffer handling) will be for later (and won't use XNEW).
- xmalloc (sizeof (struct foo)) -> XNEW (struct foo)
- xmalloc (num * sizeof (struct foo)) -> XNEWVEC (struct foo, num)
- xcalloc (1, sizeof (struct foo)) -> XCNEW (struct foo)
- xcalloc (num, sizeof (struct foo)) -> XCNEWVEC (struct foo, num)
- xrealloc (p, num * sizeof (struct foo) -> XRESIZEVEC (struct foo, p, num)
- obstack_alloc (ob, sizeof (struct foo)) -> XOBNEW (ob, struct foo)
- obstack_alloc (ob, num * sizeof (struct foo)) -> XOBNEWVEC (ob, struct foo, num)
- alloca (sizeof (struct foo)) -> XALLOCA (struct foo)
- alloca (num * sizeof (struct foo)) -> XALLOCAVEC (struct foo, num)
Some instances of xmalloc followed by memset to zero the buffer were
replaced by XCNEW or XCNEWVEC.
I regtested on x86-64, Ubuntu 14.04, but the patch touches many
architecture-specific files. For those I'll have to rely on the
buildbot or people complaining that I broke their gdb.

Fix gdb C++ compilation on Solaris (PR build/20712)
gdb 7.12 doesn't compile as C++ (tried with g++ 4.9) on Solaris (tried
10 and 12, sparc and x86). The following patch (relative to the 7.12
release, though I expect most if not all issues to be present on trunk,
too) fixes this.
Only a few of the changes bear explanation:
* Initially, compilation failed whereever defs.h. was included:

This is due to this gem in gdb/defs.h which seems to have been present
like forever:
#ifndef atof
extern double atof (const char *); /* X3.159-1989 4.10.1.1 */
#endif
In the Solaris headers, the appropriate functions are in namespace std,
thus the conflict. I've wrapped the defs.h declaration in !__cplusplus
to avoid this; perhaps it can go completely instead.
* All the casts are necessary to appease g++ and should be pretty
obvious.

and are modeled after linux-thread-db.c (try_thread_db_load_1).
The patch allowed both 32 and 64-bit C++ builds on sparc-sun-solaris2.10
and i386-pc-solaris2.10 to complete. The resulting binary hasn't seen
more than a smoke test (invoke it on itself, b main, run) yet.
When investigating the failure to detect -static-libstdc++

Replace some xmalloc-family functions with XNEW-family ones
This patch is part of the make-gdb-buildable-in-C++ effort. The idea is
to change some calls to the xmalloc family of functions to calls to the
equivalents in the XNEW family. This avoids adding an explicit cast, so
it keeps the code a bit more readable. Some of them also map relatively
well to a C++ equivalent (XNEW (struct foo) -> new foo), so it will be
possible to do scripted replacements if needed.
I only changed calls that were obviously allocating memory for one or
multiple "objects". Allocation of variable sizes (such as strings or
buffer handling) will be for later (and won't use XNEW).
- xmalloc (sizeof (struct foo)) -> XNEW (struct foo)
- xmalloc (num * sizeof (struct foo)) -> XNEWVEC (struct foo, num)
- xcalloc (1, sizeof (struct foo)) -> XCNEW (struct foo)
- xcalloc (num, sizeof (struct foo)) -> XCNEWVEC (struct foo, num)
- xrealloc (p, num * sizeof (struct foo) -> XRESIZEVEC (struct foo, p, num)
- obstack_alloc (ob, sizeof (struct foo)) -> XOBNEW (ob, struct foo)
- obstack_alloc (ob, num * sizeof (struct foo)) -> XOBNEWVEC (ob, struct foo, num)
- alloca (sizeof (struct foo)) -> XALLOCA (struct foo)
- alloca (num * sizeof (struct foo)) -> XALLOCAVEC (struct foo, num)
Some instances of xmalloc followed by memset to zero the buffer were
replaced by XCNEW or XCNEWVEC.
I regtested on x86-64, Ubuntu 14.04, but the patch touches many
architecture-specific files. For those I'll have to rely on the
buildbot or people complaining that I broke their gdb.

Fix gdb C++ compilation on Solaris (PR build/20712)
gdb 7.12 doesn't compile as C++ (tried with g++ 4.9) on Solaris (tried
10 and 12, sparc and x86). The following patch (relative to the 7.12
release, though I expect most if not all issues to be present on trunk,
too) fixes this.
Only a few of the changes bear explanation:
* Initially, compilation failed whereever defs.h. was included:
In file included from /vol/src/gnu/gdb/gdb-7.12/gdb/gdb.c:19:0:
/vol/src/gnu/gdb/gdb-7.12/gdb/defs.h:630:33: error: 'double atof(const char*)' conflicts with a previous declaration
extern double atof (const char *); /* X3.159-1989 4.10.1.1 */
^
In file included from /usr/include/stdlib.h:17:0,
from build-gnulib/import/stdlib.h:36,
from /vol/src/gnu/gdb/gdb-7.12/gdb/common/common-defs.h:32,
from /vol/src/gnu/gdb/gdb-7.12/gdb/defs.h:28,
from /vol/src/gnu/gdb/gdb-7.12/gdb/gdb.c:19:
/vol/gcc-4.9/lib/gcc/i386-pc-solaris2.10/4.9.0/include-fixed/iso/stdlib_iso.h:119:15: note: previous declaration 'double std::atof(const char*)'
extern double atof(const char *);
^
This is due to this gem in gdb/defs.h which seems to have been present
like forever:
#ifndef atof
extern double atof (const char *); /* X3.159-1989 4.10.1.1 */
#endif
In the Solaris headers, the appropriate functions are in namespace std,
thus the conflict. I've wrapped the defs.h declaration in !__cplusplus
to avoid this; perhaps it can go completely instead.
* All the casts are necessary to appease g++ and should be pretty
obvious.
* The sol-thread.c changes are here to handle
/vol/src/gnu/gdb/gdb-7.12/gdb/sol-thread.c: In function 'void _initialize_sol_thread()':
/vol/src/gnu/gdb/gdb-7.12/gdb/sol-thread.c:1252:36: error: invalid conversion from 'void*' to 'void (*)(int)' [-fpermissive]

^
/vol/src/gnu/gdb/gdb-7.12/gdb/sol-thread.c:1255:3: note: in expansion of macro 'resolve'
resolve (td_log);
^
and are modeled after linux-thread-db.c (try_thread_db_load_1).
The patch allowed both 32 and 64-bit C++ builds on sparc-sun-solaris2.10
and i386-pc-solaris2.10 to complete. The resulting binary hasn't seen
more than a smoke test (invoke it on itself, b main, run) yet.
When investigating the failure to detect -static-libstdc++
support (more below), I found two more issues which only show up with
-Werror:
/vol/src/gnu/gdb/gdb/local/gdb/procfs.c: In function 'ssd* proc_get_LDT_entry(procinfo*, int)':
/vol/src/gnu/gdb/gdb/local/gdb/procfs.c:2487:19: error: variable 'old_chain' set but not used [-Werror=unused-but-set-variable]
struct cleanup *old_chain = NULL;
^
Unless I'm mistaken, you need to run do_cleanups on every return from
the function.
Afterwards, I ran a 32-bit compilation, which (after adding
--disable-largefile to avoid
In file included from /usr/include/sys/procfs.h:28:0,
from /vol/src/gnu/gdb/gdb/local/gdb/i386-sol2-nat.c:23:
/usr/include/sys/old_procfs.h:39:2: error: #error "Cannot use procfs in the large file compilation environment"
#error "Cannot use procfs in the large file compilation environment"
^
and two more instances) revealed
/vol/src/gnu/gdb/gdb/local/gdb/top.c: In function 'void gdb_safe_append_history()':
/vol/src/gnu/gdb/gdb/local/gdb/top.c:1170:59: error: format '%d' expects argument of type 'int', but argument 3 has type 'pid_t {aka long int}' [-Werror=format=]
= xstrprintf ("%s-gdb%d~", history_filename, getpid ());
^
Fixed by casting pid_t to long and printing it as such.

Replace some xmalloc-family functions with XNEW-family ones
This patch is part of the make-gdb-buildable-in-C++ effort. The idea is
to change some calls to the xmalloc family of functions to calls to the
equivalents in the XNEW family. This avoids adding an explicit cast, so
it keeps the code a bit more readable. Some of them also map relatively
well to a C++ equivalent (XNEW (struct foo) -> new foo), so it will be
possible to do scripted replacements if needed.
I only changed calls that were obviously allocating memory for one or
multiple "objects". Allocation of variable sizes (such as strings or
buffer handling) will be for later (and won't use XNEW).
- xmalloc (sizeof (struct foo)) -> XNEW (struct foo)
- xmalloc (num * sizeof (struct foo)) -> XNEWVEC (struct foo, num)
- xcalloc (1, sizeof (struct foo)) -> XCNEW (struct foo)
- xcalloc (num, sizeof (struct foo)) -> XCNEWVEC (struct foo, num)
- xrealloc (p, num * sizeof (struct foo) -> XRESIZEVEC (struct foo, p, num)
- obstack_alloc (ob, sizeof (struct foo)) -> XOBNEW (ob, struct foo)
- obstack_alloc (ob, num * sizeof (struct foo)) -> XOBNEWVEC (ob, struct foo, num)
- alloca (sizeof (struct foo)) -> XALLOCA (struct foo)
- alloca (num * sizeof (struct foo)) -> XALLOCAVEC (struct foo, num)
Some instances of xmalloc followed by memset to zero the buffer were
replaced by XCNEW or XCNEWVEC.
I regtested on x86-64, Ubuntu 14.04, but the patch touches many
architecture-specific files. For those I'll have to rely on the
buildbot or people complaining that I broke their gdb.

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_detach
This patch constifies the target_ops method to_detach.
This is a small cleanup, but also, I think, a bug-prevention fix,
since gdb already acts as if the "args" argument here was const.
In particular, top.c:quit_force calls kill_or_detach via
iterate_over_inferiors. kill_or_detach calls target_detach, passing
the same argument each time. So, if one of these methods was not
const-correct, then kill_or_detach would change its behavior in a
strange way.
I could not build every target I modified in this patch. I've
inspected them all by hand, though. Many targets do not use the
"args" parameter; a couple pass it to atoi; and a few pass it on to
the to_detach method of the target beneath. The only code that
required a real change was in linux-nat.c, and that only needed the
introduction of a temporary variable for const-correctness.

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.

??? Is the following note still relevant? We can't get individual

|
|
|

don't bother with caching at all in that case.

|
NOTE: Since the /proc interface cannot give us individual

|
registers, we pay no attention to REGNUM, and just fetch them all.
|
|
|
|
This results in the possibility that we will do unnecessarily many
|
|
|
|
fetches, since we may be called repeatedly for individual
|
|
|
|
registers. So we cache the results, and mark the cache invalid

Use class to manage BFD reference counts
This introduces a new specialization of gdb::ref_ptr that can be used
to manage BFD reference counts. Then it changes most places in gdb to
use this new class, rather than explicit reference-counting or
cleanups. This patch removes make_cleanup_bfd_unref.
If you look you will see a couple of spots using "release" where a use
of gdb_bfd_ref_ptr would be cleaner. These will be fixed in the next
patch.
I think this patch fixes some latent bugs. For example, it seems to
me that previously objfpy_add_separate_debug_file leaked a BFD.
I'm not 100% certain that the macho_symfile_read_all_oso change is
correct. The existing code here is hard for me to follow. One goal
of this sort of automated reference counting, though, is to make it
more difficult to make logic errors; so hopefully the code is clear
now.

Use class to manage BFD reference counts
This introduces a new specialization of gdb::ref_ptr that can be used
to manage BFD reference counts. Then it changes most places in gdb to
use this new class, rather than explicit reference-counting or
cleanups. This patch removes make_cleanup_bfd_unref.
If you look you will see a couple of spots using "release" where a use
of gdb_bfd_ref_ptr would be cleaner. These will be fixed in the next
patch.
I think this patch fixes some latent bugs. For example, it seems to
me that previously objfpy_add_separate_debug_file leaked a BFD.
I'm not 100% certain that the macho_symfile_read_all_oso change is
correct. The existing code here is hard for me to follow. One goal
of this sort of automated reference counting, though, is to make it
more difficult to make logic errors; so hopefully the code is clear
now.

[IRIX] eliminate deprecated_insert_raw_breakpoint uses
The IRIX support wants to set a breakpoint to be hit when the startup
phase is complete, which is where shared libraries have been mapped
in. AFAIU, for most IRIX ports, that location is the entry point.
For MIPS IRIX however, GDB needs to set a breakpoint earlier, in
__dbx_link, as explained by:
#ifdef SYS_syssgi
/* On mips-irix, we need to stop the inferior early enough during
the startup phase in order to be able to load the shared library
symbols and insert the breakpoints that are located in these shared
libraries. Stopping at the program entry point is not good enough
because the -init code is executed before the execution reaches
that point.
So what we need to do is to insert a breakpoint in the runtime
loader (rld), more precisely in __dbx_link(). This procedure is
called by rld once all shared libraries have been mapped, but before
the -init code is executed. Unfortuantely, this is not straightforward,
as rld is not part of the executable we are running, and thus we need
the inferior to run until rld itself has been mapped in memory.
For this, we trace all syssgi() syscall exit events. Each time
we detect such an event, we iterate over each text memory maps,
get its associated fd, and scan the symbol table for __dbx_link().
When found, we know that rld has been mapped, and that we can insert
the breakpoint at the symbol address. Once the dbx_link() breakpoint
has been inserted, the syssgi() notifications are no longer necessary,
so they should be canceled. */
proc_trace_syscalls_1 (pi, SYS_syssgi, PR_SYSEXIT, FLAG_SET, 0);
#endif
The loop in irix_solib_create_inferior_hook then runs until whichever
breakpoint is hit first, the one set by solib-irix.c or the one set by
procfs.c.
Note the comment in disable_break talks about __dbx_init, but I think
that's a typo for __dbx_link:
- /* Note that it is possible that we have stopped at a location that
- is different from the location where we inserted our breakpoint.
- On mips-irix, we can actually land in __dbx_init(), so we should
- not check the PC against our breakpoint address here. See procfs.c
- for more details. */
This looks very much like referring to the loop in
irix_solib_create_inferior_hook stopping at __dbx_link instead of at
the entry point.
What this patch does is convert these deprecated raw breakpoints to
standard solib_event breakpoints. When the first solib-event
breakpoint is hit, we delete all solib-event breakpoints. We do that
in the so_ops->handle_event hook.
This allows getting rid of the loop in irix_solib_create_inferior_hook
completely, which should allow properly handling signals and other
events in the early startup phase, like in SVR4.
Built on x86_64 Fedora 20 with --enable-targets=all (builds
solib-irix.c).
Joel tested that with an earlier version of this patch "info shared"
after starting a program gave the same list of shared libraries as
before.

Use target_continue{,_no_signal} instead of target_resume
This commit implements a new function, target_continue, on top of the
target_resume function. Then, it replaces all calls to target_resume
by calls to target_continue or to the already existing
target_continue_no_signal.
This is one of the (many) necessary steps needed to consolidate the
target interface between GDB and gdbserver. In particular, I am
interested in the impact this change will have on the unification of
the fork_inferior function (which I have been working on).
Tested on the BuildBot, no regressions introduced.

Use target_continue{,_no_signal} instead of target_resume
This commit implements a new function, target_continue, on top of the
target_resume function. Then, it replaces all calls to target_resume
by calls to target_continue or to the already existing
target_continue_no_signal.
This is one of the (many) necessary steps needed to consolidate the
target interface between GDB and gdbserver. In particular, I am
interested in the impact this change will have on the unification of
the fork_inferior function (which I have been working on).

Fix gdb C++ compilation on Solaris (PR build/20712)
gdb 7.12 doesn't compile as C++ (tried with g++ 4.9) on Solaris (tried
10 and 12, sparc and x86). The following patch (relative to the 7.12
release, though I expect most if not all issues to be present on trunk,
too) fixes this.
Only a few of the changes bear explanation:
* Initially, compilation failed whereever defs.h. was included:
In file included from /vol/src/gnu/gdb/gdb-7.12/gdb/gdb.c:19:0:
/vol/src/gnu/gdb/gdb-7.12/gdb/defs.h:630:33: error: 'double atof(const char*)' conflicts with a previous declaration
extern double atof (const char *); /* X3.159-1989 4.10.1.1 */
^
In file included from /usr/include/stdlib.h:17:0,

extern double atof(const char *);
^
This is due to this gem in gdb/defs.h which seems to have been present
like forever:
#ifndef atof
extern double atof (const char *); /* X3.159-1989 4.10.1.1 */
#endif
In the Solaris headers, the appropriate functions are in namespace std,
thus the conflict. I've wrapped the defs.h declaration in !__cplusplus
to avoid this; perhaps it can go completely instead.
* All the casts are necessary to appease g++ and should be pretty
obvious.
* The sol-thread.c changes are here to handle
/vol/src/gnu/gdb/gdb-7.12/gdb/sol-thread.c: In function 'void _initialize_sol_thread()':
/vol/src/gnu/gdb/gdb-7.12/gdb/sol-thread.c:1252:36: error: invalid conversion from 'void*' to 'void (*)(int)' [-fpermissive]

^
/vol/src/gnu/gdb/gdb-7.12/gdb/sol-thread.c:1255:3: note: in expansion of macro 'resolve'
resolve (td_log);
^
and are modeled after linux-thread-db.c (try_thread_db_load_1).
The patch allowed both 32 and 64-bit C++ builds on sparc-sun-solaris2.10
and i386-pc-solaris2.10 to complete. The resulting binary hasn't seen
more than a smoke test (invoke it on itself, b main, run) yet.
When investigating the failure to detect -static-libstdc++
support (more below), I found two more issues which only show up with
-Werror:
/vol/src/gnu/gdb/gdb/local/gdb/procfs.c: In function 'ssd* proc_get_LDT_entry(procinfo*, int)':
/vol/src/gnu/gdb/gdb/local/gdb/procfs.c:2487:19: error: variable 'old_chain' set but not used [-Werror=unused-but-set-variable]
struct cleanup *old_chain = NULL;
^
Unless I'm mistaken, you need to run do_cleanups on every return from
the function.
Afterwards, I ran a 32-bit compilation, which (after adding
--disable-largefile to avoid
In file included from /usr/include/sys/procfs.h:28:0,

and two more instances) revealed
/vol/src/gnu/gdb/gdb/local/gdb/top.c: In function 'void gdb_safe_append_history()':

^
Fixed by casting pid_t to long and printing it as such.

Return target_xfer_status in to_xfer_partial
This patch does the conversion of to_xfer_partial from
LONGEST (*to_xfer_partial) (struct target_ops *ops,
enum target_object object, const char *annex,
gdb_byte *readbuf, const gdb_byte *writebuf,
ULONGEST offset, ULONGEST len);
to
enum target_xfer_status (*to_xfer_partial) (struct target_ops *ops,
enum target_object object, const char *annex,
gdb_byte *readbuf, const gdb_byte *writebuf,
ULONGEST offset, ULONGEST len, ULONGEST *xfered_len);
It changes to_xfer_partial return the transfer status and the transfered
length by *XFERED_LEN. Generally, the return status has three stats,
- TARGET_XFER_OK,
- TARGET_XFER_EOF,
- TARGET_XFER_E_XXXX,
See the comments to them in 'enum target_xfer_status'. Note that
Pedro suggested not name TARGET_XFER_DONE, as it is confusing,
compared with "TARGET_XFER_OK". We finally name it TARGET_XFER_EOF.
With this change, GDB core can handle unavailable data in a convenient
way.
The rationale behind this change was mentioned here
https://sourceware.org/ml/gdb-patches/2013-10/msg00761.html
Consider an object/value like this:
0 100 150 200 512
DDDDDDDDDDDxxxxxxxxxDDDDDD...DDIIIIIIIIIIII..III
where D is valid data, and xxx is unavailable data, and I is beyond
the end of the object (Invalid). Currently, if we start the
xfer at 0, requesting, say 512 bytes, we'll first get back 100 bytes.
The xfer machinery then retries fetching [100,512), and gets back
TARGET_XFER_E_UNAVAILABLE. That's sufficient when you're either
interested in either having the whole of the 512 bytes available,
or erroring out. But, in this scenario, we're interested in
the data at [150,512). The problem is that the last
TARGET_XFER_E_UNAVAILABLE gives us no indication where to
start the read next. We'd need something like:
get me [0,512) >>>
<<< here's [0,100), *xfered_len is 100, returns TARGET_XFER_OK
get me [100,512) >>> (**1)
<<< [100,150) is unavailable, *xfered_len is 50, return TARGET_XFER_E_UNAVAILABLE.
get me [150,512) >>>
<<< here's [150,200), *xfered_len is 50, return TARGET_XFER_OK.
get me [200,512) >>>
<<< no more data, return TARGET_XFER_EOF.
This naturally implies pushing down the decision of whether
to return TARGET_XFER_E_UNAVAILABLE or something else
down to the target. (Which kinds of leads back to tfile
itself reading from RO memory from file (though we could
export a function in exec.c for that that tfile delegates to,
instead of re-adding the old code).
Beside this change, we also add a macro TARGET_XFER_STATUS_ERROR_P to
check whether a status is an error or not, to stop using "status < 0".
This patch also eliminates the comparison between status and 0.
No target implementations to to_xfer_partial adapts this new
interface. The interface still behaves as before.

Fix interrupt-noterm.exp on targets always in non-stop

+testcase src/gdb/testsuite/gdb.base/interrupt-noterm.exp completed in 10 seconds
That is, we get "[$thread] #1 stopped" instead of SIGINT.
The issue is that we don't currently distinguish send
"interrupt/ctrl-c" to target terminal vs "stop/pause" thread well;
both cases go through "target_stop".
And then, the native Linux backend (linux-nat.c) implements
target_stop with SIGSTOP in non-stop mode, and SIGINT in all-stop
mode. Since "maint set target-non-stop on" forces the backend to be
always running in non-stop mode, even though the user-visible behavior
is "set non-stop" is "off", "interrupt" causes a SIGSTOP instead of
the SIGINT the test expects.
Fix this by introducing a target_interrupt method to use in the
"interrupt/ctrl-c" case, so "set non-stop off" can always work the
same irrespective of "maint set target-non-stop on/off". I'm
explictly considering changing the "set non-stop on" behavior as out
of scope here.
Most of the patch is an across-the-board rename of to_stop hook
implementations to to_interrupt. The only targets where something
more than a rename is being done are linux-nat.c and remote.c, which
are the only targets that support async, and thus are the only ones
the core side calls target_stop on.

Consolidate target_mourn_inferior between GDB and gdbserver
This patch consolidates the API of target_mourn_inferior between GDB
and gdbserver, in my continuing efforts to make sharing the
fork_inferior function possible between both.
GDB's version of the function did not care about the inferior's ptid
being mourned, but gdbserver's needed to know this information. Since
it actually makes sense to pass the ptid as an argument, instead of
depending on a global value directly (which GDB's version did), I
decided to make the generic API to accept it. I then went on and
extended all calls being made on GDB to include a ptid argument (which
ended up being inferior_ptid most of the times, anyway), and now we
have a more sane interface.
On GDB's side, after talking to Pedro a bit about it, we decided that
just an assertion to make sure that the ptid being passed is equal to
inferior_ptid would be enough for now, on the GDB side. We can remove
the assertion and perform more operations later if we ever pass
anything different than inferior_ptid.
Regression tested on our BuildBot, everything OK.
I'd appreciate a special look at gdb/windows-nat.c's modification
because I wasn't really sure what to do there. It seemed to me that
maybe I should build a ptid out of the process information there, but
then I am almost sure the assertion on GDB's side would trigger.

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.

Share fork_inferior et al with gdbserver
This is the most important (and the biggest, sorry) patch of the
series. It moves fork_inferior from gdb/fork-child.c to
nat/fork-inferior.c and makes all the necessary adjustments to both
GDB and gdbserver to make sure everything works OK.
There is no "most important change" with this patch; all changes are
made in a progressive way, making sure that gdbserver had the
necessary features while not breaking GDB at the same time.
I decided to go ahead and implement a partial support for starting the
inferior with a shell on gdbserver, although the full feature comes in
the next patch. The user won't have the option to disable the
startup-with-shell, and also won't be able to change which shell
gdbserver will use (other than setting the $SHELL environment
variable, that is).
Everything is working as expected, and no regressions were present
during the tests.

/* On mips-irix, we need to stop the inferior early enough during

the startup phase in order to be able to load the shared library

|
symbols and insert the breakpoints that are located in these shared
|
|
|
|
libraries. Stopping at the program entry point is not good enough
|
|
|
|
because the -init code is executed before the execution reaches
|
|
|
|
that point.
|
|
|
|
|
|
|
|
So what we need to do is to insert a breakpoint in the runtime
|
|
|
|
loader (rld), more precisely in __dbx_link(). This procedure is
|
|
|
|
called by rld once all shared libraries have been mapped, but before
|
2011-01-10 21:38:51 +01:00
|
|
|
the -init code is executed. Unfortuantely, this is not straightforward,
|
2004-08-27 15:37:42 +02:00
|
|

as rld is not part of the executable we are running, and thus we need

the inferior to run until rld itself has been mapped in memory.

For this, we trace all syssgi() syscall exit events. Each time
|
|
|
|
we detect such an event, we iterate over each text memory maps,
|
|
|
|
get its associated fd, and scan the symbol table for __dbx_link().
|
|
|
|
When found, we know that rld has been mapped, and that we can insert
|
|
|
|
the breakpoint at the symbol address. Once the dbx_link() breakpoint
|
|
|
|
has been inserted, the syssgi() notifications are no longer necessary,
|
|
|
|
so they should be canceled. */

C++-fy and prepare for sharing fork_inferior
As a preparation for the next patch, which will move fork_inferior
from GDB to common/ (and therefore share it with gdbserver), it is
interesting to convert a few functions to C++.
This patch touches functions related to parsing command-line arguments
to the inferior (see gdb/fork-child.c:breakup_args), the way the
arguments are stored on fork_inferior (using std::vector instead of
char **), and the code responsible for dealing with argv also on
gdbserver.
I've taken this opportunity and decided to constify a few arguments to
fork_inferior/create_inferior as well, in order to make the code
cleaner. And now, on gdbserver, we're using xstrdup everywhere and
aren't checking for memory allocation failures anymore, as requested
by Pedro:

IMO this refactoring was very good to increase the readability of the
code as well, because some parts of the argument handling were
unnecessarily confusing before.

2000-01-06 04:07:20 +01:00

|
just do this the normal way (via execlp, which operates by
|
|
|
|
attempting an exec for each element of the PATH until it
|
|
|
|
finds one which succeeds), then there will be an exec for
|
|
|
|
each failed attempt, each of which will cause a PR_SYSEXIT

stop, and we won't know how to distinguish the PR_SYSEXIT's

for these failed execs with the ones for successful execs

So I can't think of anything better than to search the PATH

condition; if we find a file now and it is deleted before we

|
|
exec it, we lose, even if the deletion leaves a valid file
|
|
|
|
further down in the PATH, (2) there is no way to know exactly
|
|
|
|
what an executable (in the sense of "capable of being
|
|
|
|
exec'd") file is. Using access() loses because it may lose
|
|
|
|
if the caller is the superuser; failing to use it loses if
|
|
|
|
there are ACLs or some such. */

Fix gdb C++ compilation on Solaris (PR build/20712)
gdb 7.12 doesn't compile as C++ (tried with g++ 4.9) on Solaris (tried
10 and 12, sparc and x86). The following patch (relative to the 7.12
release, though I expect most if not all issues to be present on trunk,
too) fixes this.
Only a few of the changes bear explanation:
* Initially, compilation failed whereever defs.h. was included:
In file included from /vol/src/gnu/gdb/gdb-7.12/gdb/gdb.c:19:0:
/vol/src/gnu/gdb/gdb-7.12/gdb/defs.h:630:33: error: 'double atof(const char*)' conflicts with a previous declaration
extern double atof (const char *); /* X3.159-1989 4.10.1.1 */
^
In file included from /usr/include/stdlib.h:17:0,
from build-gnulib/import/stdlib.h:36,

extern double atof(const char *);
^
This is due to this gem in gdb/defs.h which seems to have been present
like forever:
#ifndef atof
extern double atof (const char *); /* X3.159-1989 4.10.1.1 */
#endif
In the Solaris headers, the appropriate functions are in namespace std,
thus the conflict. I've wrapped the defs.h declaration in !__cplusplus
to avoid this; perhaps it can go completely instead.
* All the casts are necessary to appease g++ and should be pretty
obvious.
* The sol-thread.c changes are here to handle
/vol/src/gnu/gdb/gdb-7.12/gdb/sol-thread.c: In function 'void _initialize_sol_thread()':
/vol/src/gnu/gdb/gdb-7.12/gdb/sol-thread.c:1252:36: error: invalid conversion from 'void*' to 'void (*)(int)' [-fpermissive]

^

resolve (td_log);
^
and are modeled after linux-thread-db.c (try_thread_db_load_1).
The patch allowed both 32 and 64-bit C++ builds on sparc-sun-solaris2.10
and i386-pc-solaris2.10 to complete. The resulting binary hasn't seen
more than a smoke test (invoke it on itself, b main, run) yet.
When investigating the failure to detect -static-libstdc++
support (more below), I found two more issues which only show up with
-Werror:
/vol/src/gnu/gdb/gdb/local/gdb/procfs.c: In function 'ssd* proc_get_LDT_entry(procinfo*, int)':
/vol/src/gnu/gdb/gdb/local/gdb/procfs.c:2487:19: error: variable 'old_chain' set but not used [-Werror=unused-but-set-variable]
struct cleanup *old_chain = NULL;
^
Unless I'm mistaken, you need to run do_cleanups on every return from
the function.
Afterwards, I ran a 32-bit compilation, which (after adding
--disable-largefile to avoid
In file included from /usr/include/sys/procfs.h:28:0,
from /vol/src/gnu/gdb/gdb/local/gdb/i386-sol2-nat.c:23:

#error "Cannot use procfs in the large file compilation environment"

and two more instances) revealed
/vol/src/gnu/gdb/gdb/local/gdb/top.c: In function 'void gdb_safe_append_history()':
/vol/src/gnu/gdb/gdb/local/gdb/top.c:1170:59: error: format '%d' expects argument of type 'int', but argument 3 has type 'pid_t {aka long int}' [-Werror=format=]
= xstrprintf ("%s-gdb%d~", history_filename, getpid ());
^
Fixed by casting pid_t to long and printing it as such.

Share fork_inferior et al with gdbserver
This is the most important (and the biggest, sorry) patch of the
series. It moves fork_inferior from gdb/fork-child.c to
nat/fork-inferior.c and makes all the necessary adjustments to both
GDB and gdbserver to make sure everything works OK.
There is no "most important change" with this patch; all changes are
made in a progressive way, making sure that gdbserver had the
necessary features while not breaking GDB at the same time.
I decided to go ahead and implement a partial support for starting the
inferior with a shell on gdbserver, although the full feature comes in
the next patch. The user won't have the option to disable the
startup-with-shell, and also won't be able to change which shell
gdbserver will use (other than setting the $SHELL environment
variable, that is).
Everything is working as expected, and no regressions were present
during the tests.

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.

add "this" pointers to more target APIs
A subsequent pass introduces delegation helper functions to the target
API. This delegation is much cleaner if the target_ops pointer is
directly available at delegation time.
This patch adds the "this" pointer to various to_* methods for this
purpose.
This updates a number of ports which I am unable to test. Please give
them a look-over. Any possible problem here is trivial, though, as
all that is required is adding an argument to a function.

iterate_over_mappings (procinfo *pi, find_memory_region_ftype child_func,

procfs.c: iterate_over_mappings callback has wrong profile.
The function proc_find_memory_regions calls iterate_over_mappings as
follow:
> return iterate_over_mappings (pi, func, data,
> find_memory_regions_callback);
The problem is that both func and find_memory_regions_callback
do not match the profile expected by iterate_over_mappings:
> iterate_over_mappings (procinfo *pi, int (*child_func) (), void *data,
> int (*func) (struct prmap *map,
> int (*child_func) (),
> void *data))
We cannot change proc_find_memory_regions such that FUNC is a pointer
to a function that takes no argument (in place of the 6 that it has).
This is because proc_find_memory_regions is used as a target_ops method.
However, it turns out that changing iterate_over_mappings to conform
to the profile imposed by the target_ops vector is possible without
much effort.
gdb/ChangeLog:
* procfs.c (iterate_over_mappings_cb_ftype): New typedef.
(iterate_over_mappings): Adjust function profile. Add declaration.
(insert_dbx_link_bpt_in_region, info_mappings_callback):
Adjust accordingly.

info_mappings_callback (struct prmap *map, find_memory_region_ftype ignore,
|
procfs.c: iterate_over_mappings callback has wrong profile.
The function proc_find_memory_regions calls iterate_over_mappings as
follow:
> return iterate_over_mappings (pi, func, data,
> find_memory_regions_callback);
The problem is that both func and find_memory_regions_callback
do not match the profile expected by iterate_over_mappings:
> iterate_over_mappings (procinfo *pi, int (*child_func) (), void *data,
> int (*func) (struct prmap *map,
> int (*child_func) (),
> void *data))
We cannot change proc_find_memory_regions such that FUNC is a pointer
to a function that takes no argument (in place of the 6 that it has).
This is because proc_find_memory_regions is used as a target_ops method.
However, it turns out that changing iterate_over_mappings to conform
to the profile imposed by the target_ops vector is possible without
much effort.
gdb/ChangeLog:
* procfs.c (iterate_over_mappings_cb_ftype): New typedef.
(iterate_over_mappings): Adjust function profile. Add declaration.
(insert_dbx_link_bpt_in_region, info_mappings_callback):
Adjust accordingly.

Introduce gdb_argv, a class wrapper for buildargv
This introduces gdb_argv, a class wrapping an "argv" pointer; that is,
a pointer to a NULL-terminated array of char*, where both the array
and each non-NULL element in the array are xmalloc'd.
This patch then changes most users of gdb_buildargv to use gdb_argv

Introduce gdb_argv, a class wrapper for buildargv
This introduces gdb_argv, a class wrapping an "argv" pointer; that is,
a pointer to a NULL-terminated array of char*, where both the array
and each non-NULL element in the array are xmalloc'd.
This patch then changes most users of gdb_buildargv to use gdb_argv
instead.

Remove save_inferior_ptid
This removes save_inferior_ptid, a cleanup function, in favor of
scoped_restore.
This also fixes a possible (it seems unlikely that it could happen in
practice) memory leak -- save_inferior_ptid should have used
make_cleanup_dtor, because it allocated memory.
I tested this on the buildbot. However, there are two caveats to
this. First, sometimes it seems I misread the results. Second, I
think this patch touches some platforms that can't be tested by the
buildbot. So, extra care seems warranted.

Fix gdb C++ compilation on Solaris (PR build/20712)
gdb 7.12 doesn't compile as C++ (tried with g++ 4.9) on Solaris (tried
10 and 12, sparc and x86). The following patch (relative to the 7.12
release, though I expect most if not all issues to be present on trunk,
too) fixes this.
Only a few of the changes bear explanation:
* Initially, compilation failed whereever defs.h. was included:
In file included from /vol/src/gnu/gdb/gdb-7.12/gdb/gdb.c:19:0:
/vol/src/gnu/gdb/gdb-7.12/gdb/defs.h:630:33: error: 'double atof(const char*)' conflicts with a previous declaration
extern double atof (const char *); /* X3.159-1989 4.10.1.1 */
^
In file included from /usr/include/stdlib.h:17:0,
from build-gnulib/import/stdlib.h:36,
from /vol/src/gnu/gdb/gdb-7.12/gdb/common/common-defs.h:32,
from /vol/src/gnu/gdb/gdb-7.12/gdb/defs.h:28,
from /vol/src/gnu/gdb/gdb-7.12/gdb/gdb.c:19:
/vol/gcc-4.9/lib/gcc/i386-pc-solaris2.10/4.9.0/include-fixed/iso/stdlib_iso.h:119:15: note: previous declaration 'double std::atof(const char*)'
extern double atof(const char *);
^
This is due to this gem in gdb/defs.h which seems to have been present
like forever:
#ifndef atof
extern double atof (const char *); /* X3.159-1989 4.10.1.1 */
#endif
In the Solaris headers, the appropriate functions are in namespace std,
thus the conflict. I've wrapped the defs.h declaration in !__cplusplus
to avoid this; perhaps it can go completely instead.
* All the casts are necessary to appease g++ and should be pretty
obvious.
* The sol-thread.c changes are here to handle
/vol/src/gnu/gdb/gdb-7.12/gdb/sol-thread.c: In function 'void _initialize_sol_thread()':
/vol/src/gnu/gdb/gdb-7.12/gdb/sol-thread.c:1252:36: error: invalid conversion from 'void*' to 'void (*)(int)' [-fpermissive]

^
/vol/src/gnu/gdb/gdb-7.12/gdb/sol-thread.c:1255:3: note: in expansion of macro 'resolve'
resolve (td_log);
^
and are modeled after linux-thread-db.c (try_thread_db_load_1).
The patch allowed both 32 and 64-bit C++ builds on sparc-sun-solaris2.10
and i386-pc-solaris2.10 to complete. The resulting binary hasn't seen
more than a smoke test (invoke it on itself, b main, run) yet.
When investigating the failure to detect -static-libstdc++
support (more below), I found two more issues which only show up with
-Werror:
/vol/src/gnu/gdb/gdb/local/gdb/procfs.c: In function 'ssd* proc_get_LDT_entry(procinfo*, int)':
/vol/src/gnu/gdb/gdb/local/gdb/procfs.c:2487:19: error: variable 'old_chain' set but not used [-Werror=unused-but-set-variable]
struct cleanup *old_chain = NULL;
^
Unless I'm mistaken, you need to run do_cleanups on every return from
the function.
Afterwards, I ran a 32-bit compilation, which (after adding
--disable-largefile to avoid
In file included from /usr/include/sys/procfs.h:28:0,
from /vol/src/gnu/gdb/gdb/local/gdb/i386-sol2-nat.c:23:
/usr/include/sys/old_procfs.h:39:2: error: #error "Cannot use procfs in the large file compilation environment"
#error "Cannot use procfs in the large file compilation environment"
^
and two more instances) revealed
/vol/src/gnu/gdb/gdb/local/gdb/top.c: In function 'void gdb_safe_append_history()':
/vol/src/gnu/gdb/gdb/local/gdb/top.c:1170:59: error: format '%d' expects argument of type 'int', but argument 3 has type 'pid_t {aka long int}' [-Werror=format=]
= xstrprintf ("%s-gdb%d~", history_filename, getpid ());
^
Fixed by casting pid_t to long and printing it as such.
