Commit 00431a78b28f ("Use thread_info and inferior pointers more
throughout") missed updating some callers, like e.g.,:
gdb/remote-sim.c: In member function 'virtual void gdbsim_target::mourn_inferior()':
gdb/remote-sim.c:1198:50: error: cannot convert 'ptid_t' to 'thread_info*' for argument '1' to 'void delete_thread_silent(thread_info*)'
delete_thread_silent (sim_data->remote_sim_ptid);
gdb/mygit/src/gdb/procfs.c: In member function ‘virtual void procfs_target::detach(inferior*, int)’:
gdb/mygit/src/gdb/procfs.c:1931:23: error: invalid conversion from ‘int’ to ‘inferior*’ [-fpermissive]

gdb/mygit/src/gdb/inferior.h:476:13: note: initializing argument 1 of ‘void detach_inferior(inferior*)’
etc.
This fixes it.
The delete_thread_silent calls in both go32-nat.c and remote-sim.c are
unnecessary because generic_mourn_inferior calls exit_inferior, which
deletes the inferior's threads.

The buildbot pointed out that arm-linux-nat.c was not properly using
"beneath" as a method. A search showed a few more places with this
issue.

arm-linux-nat.c. Nevertheless I'm checking this in under the obvious
rule.

The recent C++ification of target_ops replaced references to the old
"current_target" squashed target throughout with references to a
"target_stack" pointer. I had picked the "target_stack" name very
early in the multi-target work, and managed to stick with it, even
though it's a bit of a misnomer, since it isn't really a "target
stack" object, but a pointer into the current top target in the stack.
As I'm splitting more pieces off of the multi-target branch, I've come
to think that it's better to rename it now. A following patch will
introduce a new class to represent a target stack, and "target_stack"
would be _its_ ideal name. (In the branch, the class is called
a_target_stack to work around the clash.)
Thus this commit renames target_stack to current_top_target and
replaces all references throughout. Also, while at it,
current_top_target is made a function instead of a pointer, to make it
possible to change its internal implementation without leaking
implementation details out. In a couple patches, the implementation
of the function will change to refer to a target stack object, and
then further down the multi-target work, it'll change again to find
the right target stack for the current inferior.

I.e., use C++ virtual methods and inheritance instead of tables of
function pointers.
Unfortunately, there's no way to do a smooth transition. ALL native
targets in the tree must be converted at the same time. I've tested
all I could with cross compilers and with help from GCC compile farm,
but naturally I haven't been able to test many of the ports. Still, I
made a best effort to port everything over, and while I expect some
build problems due to typos and such, which should be trivial to fix,
I don't expect any design problems.
* Implementation notes:
- The flattened current_target is gone. References to current_target
or current_target.beneath are replaced with references to
target_stack (the top of the stack) directly.
- To keep "set debug target" working, this adds a new debug_stratum
layer that sits on top of the stack, prints the debug, and delegates
to the target beneath.
In addition, this makes the shortname and longname properties of
target_ops be virtual methods instead of data fields, and makes the
debug target defer those to the target beneath. This is so that
debug code sprinkled around that does "if (debugtarget) ..." can
transparently print the name of the target beneath.
A patch later in the series actually splits out the
shortname/longname methods to a separate structure, but I preferred
to keep that chance separate as it is associated with changing a bit
the design of how targets are registered and open.
- Since you can't check whether a C++ virtual method is overridden,
the old method of checking whether a target_ops implements a method
by comparing the function pointer must be replaced with something
else.
Some cases are fixed by adding a parallel "can_do_foo" target_ops
methods. E.g.,:
+ for (t = target_stack; t != NULL; t = t->beneath)
{
- if (t->to_create_inferior != NULL)
+ if (t->can_create_inferior ())
break;
}
Others are fixed by changing void return type to bool or int return
type, and have the default implementation return false or -1, to
indicate lack of support.
- make-target-delegates was adjusted to generate C++ classes and
methods.
It needed tweaks to grok "virtual" in front of the target method
name, and for the fact that methods are no longer function pointers.
(In particular, the current code parsing the return type was simple
because it could simply parse up until the '(' in '(*to_foo)'.
It now generates a couple C++ classes that inherit target_ops:
dummy_target and debug_target.
Since we need to generate the class declarations as well, i.e., we
need to emit methods twice, we now generate the code in two passes.
- The core_target global is renamed to avoid conflict with the
"core_target" class.
- ctf/tfile targets
init_tracefile_ops is replaced by a base class that is inherited by
both ctf and tfile.
- bsd-uthread
The bsd_uthread_ops_hack hack is gone. It's not needed because
nothing was extending a target created by bsd_uthread_target.
- remote/extended-remote targets
This is a first pass, just enough to C++ify target_ops.
A later pass will convert more free functions to methods, and make
remote_state be truly per remote instance, allowing multiple
simultaneous instances of remote targets.
- inf-child/"native" is converted to an actual base class
(inf_child_target), that is inherited by all native targets.
- GNU/Linux
The old weird double-target linux_ops mechanism in linux-nat.c, is
gone, replaced by adding a few virtual methods to linux-nat.h's
target_ops, called low_XXX, that the concrete linux-nat
implementations override. Sort of like gdbserver's
linux_target_ops, but simpler, for requiring only one
target_ops-like hierarchy, which spares implementing the same method
twice when we need to forward the method to a low implementation.
The low target simply reimplements the target_ops method directly in
that case.
There are a few remaining linux-nat.c hooks that would be better
converted to low_ methods like above too. E.g.:
linux_nat_set_new_thread (t, x86_linux_new_thread);
linux_nat_set_new_fork (t, x86_linux_new_fork);
linux_nat_set_forget_process
That'll be done in a follow up patch.
- We can no longer use functions like x86_use_watchpoints to install
custom methods on an arbitrary base target.
The patch replaces instances of such a pattern with template mixins.
For example memory_breakpoint_target defined in target.h, or
x86_nat_target in x86-nat.h.
- linux_trad_target, MIPS and Alpha GNU/Linux
The code in the new linux-nat-trad.h/c files which was split off of
inf-ptrace.h/c recently, is converted to a C++ base class, and used
by the MIPS and Alpha GNU/Linux ports.
- BSD targets
The
$architecture x NetBSD/OpenBSD/FreeBSD
support matrix complicates things a bit. There's common BSD target
code, and there's common architecture-specific code shared between
the different BSDs. Currently, all that is stiched together to form
a final target, via the i386bsd_target, x86bsd_target,
fbsd_nat_add_target functions etc.
This introduces new fbsd_nat_target, obsd_nat_target and
nbsd_nat_target classes that serve as base/prototype target for the
corresponding BSD variant.
And introduces generic i386/AMD64 BSD targets, to be used as
template mixin to build a final target. Similarly, a generic SPARC
target is added, used by both BSD and Linux ports.
- bsd_kvm_add_target, BSD libkvm target
I considered making bsd_kvm_supply_pcb a virtual method, and then
have each port inherit bsd_kvm_target and override that method, but
that was resulting in lots of unjustified churn, so I left the
function pointer mechanism alone.

Now that procfs.c is only ever used by Solaris, and, both x86 and
SPARC Solaris support watchpoints (*), we don't need the separate
procfs_use_watchpoints function. Getting rid of it simplifies
C++ification of target_ops.
(*) and I assume that any other Solaris port would use the same kernel
debug API interfaces for watchpoints. Otherwise, we can worry about
it if it ever happens.

scoped_fd in more places missed removing one do_cleanups call.

This converts observers from using a special source-generating script
to be plain C++. This version of the patch takes advantage of C++11
by using std::function and variadic templates; incorporates Pedro's
patches; and renames the header file to "observable.h" (this change
eliminates the need for a clean rebuild).
Note that Pedro's patches used a template lambda in tui-hooks.c, but
this failed to compile on some buildbot instances (presumably due to
differing C++ versions); I replaced this with an ordinary template
function.
Regression tested on the buildbot.

In my multi-target branch I ran into problems with GDB's terminal
handling that exist in master as well, with multi-inferior debugging.
This patch adds a testcase for said problems
(gdb.multi/multi-term-settings.exp), fixes the problems, fixes PR
gdb/13211 as well (and adds a testcase for that too,
gdb.base/interrupt-daemon.exp).
The basis of the problem I ran into is the following. Consider a
scenario where you have:
- inferior 1 - started with "attach", process is running on some
other terminal.
- inferior 2 - started with "run", process is sharing gdb's terminal.
In this scenario, when you stop/resume both inferiors, you want GDB to
save/restore the terminal settings of inferior 2, the one that is
sharing GDB's terminal. I.e., you want inferior 2 to "own" the
terminal (in target_terminal::is_ours/target_terminal::is_inferior
sense).
Unfortunately, that's not what you get currently. Because GDB doesn't
know whether an attached inferior is actually sharing GDB's terminal,
it tries to save/restore its settings anyway, ignoring errors. In
this case, this is pointless, because inferior 1 is running on a
different terminal, but GDB doesn't know better.
And then, because it is only possible to have the terminal settings of
a single inferior be in effect at a time, or make one inferior/pgrp be
the terminal's foreground pgrp (aka, only one inferior can "own" the
terminal, ignoring fork children here), if GDB happens to try to
restore the terminal settings of inferior 1 first, then GDB never
restores the terminal settings of inferior 2.
This patch fixes that and a few things more along the way:
- Moves enum target_terminal::terminal_state out of the
target_terminal class (it's currently private) and makes it a
scoped enum so that it can be easily used elsewhere.
- Replaces the inflow.c:terminal_is_ours boolean with a
target_terminal_state variable. This allows distinguishing is_ours
and is_ours_for_output states. This allows finally making
child_terminal_ours_1 do something with its "output_only"
parameter.
- Makes each inferior have its own copy of the
is_ours/is_ours_for_output/is_inferior state.
- Adds a way for GDB to tell whether the inferior is sharing GDB's
terminal. Works best on Linux and Solaris; the fallback works just
as well as currently.
- With that, we can remove the inf->attach_flag tests from
child_terminal_inferior/child_terminal_ours.
- Currently target_ops.to_ours is responsible for both saving the
current inferior's terminal state, and restoring gdb's state.
Because each inferior has its own terminal state (possibly handled
by different targets in a multi-target world, even), we need to
split the inferior-saving part from the gdb-restoring part. The
patch adds a new target_ops.to_save_inferior target method for
that.
- Adds a new target_terminal::save_inferior() function, so that
sequences like:
scoped_restore_terminal_state save_state;
target_terminal::ours_for_output ();
... restore back inferiors that were
target_terminal_state::is_inferior before back to is_inferior, and
leaves inferiors that were is_ours alone.
- Along the way, this adds a default implementation of
target_pass_ctrlc to inflow.c (for inf-child.c), that handles
passing the Ctrl-C to a process running on GDB's terminal or to
some other process otherwise.
- Similarly, adds a new target default implementation of
target_interrupt, for the "interrupt" command. The current
implementation of this hook in inf-ptrace.c kills the whole process
group, but that's incorrect/undesirable because we may not be
attached to all processes in the process group. And also, it's
incorrect because inferior_process_group() doesn't really return
the inferior's real process group id if the inferior is not a
process group leader... This is the cause of PR gdb/13211 [1],
which this patch fixes. While at it, that target method's "ptid"
parameter is eliminated, because it's not really used.
- A new test is included that exercises and fixes PR gdb/13211, and
also fixes a GDB issue reported on stackoverflow that I ran into
while working on this [2]. The problem is similar to PR gdb/13211,
except that it also triggers with Ctrl-C. When debugging a daemon
(i.e., a process that disconnects from the controlling terminal and
is not a process group leader, then Ctrl-C doesn't work, you just
can't interrupt the inferior at all, resulting in a hung debug
session. The problem is that since the inferior is no longer
associated with gdb's session / controlling terminal, then trying
to put the inferior in the foreground fails. And so Ctrl-C never
reaches the inferior directly. pass_signal is only used when the
inferior is attached, but that is not the case here. This is fixed
by the new child_pass_ctrlc. Without the fix, the new
interrupt-daemon.exp testcase fails with timeout waiting for a
SIGINT that never arrives.
[1] PR gdb/13211 - Async / Process group and interrupt not working
https://sourceware.org/bugzilla/show_bug.cgi?id=13211
[2] GDB not reacting Ctrl-C when after fork() and setsid()
https://stackoverflow.com/questions/46101292/gdb-not-reacting-ctrl-c-when-after-fork-and-setsid
Note this patch does _not_ fix:
- PR gdb/14559 - The 'interrupt' command does not work if sigwait is in use
https://sourceware.org/bugzilla/show_bug.cgi?id=14559
- PR gdb/9425 - When using "sigwait" GDB doesn't trap SIGINT. Ctrl+C terminates program when should break gdb.
https://sourceware.org/bugzilla/show_bug.cgi?id=9425
The only way to fix that that I know of (without changing the kernel)
is to make GDB put inferiors in a separate session (create a
pseudo-tty master/slave pair, make the inferior run with the slave as
its terminal, and have gdb pump output/input on the master end).

The to_detach target_ops method implementations are currently expected
to work on current_inferior/inferior_ptid. In order to make things more
explicit, and remove some "shadow" parameter passing through globals,
this patch adds an "inferior" parameter to to_detach. Implementations
will be expected to use this instead of relying on the global. However,
to keep things simple, this patch only does the minimum that is
necessary to add the parameter. The following patch gives an example of
how one such implementation would be adapted. If the approach is deemed
good, we can then look into adapting more implementations. Until then,
they'll continue to work as they do currently.

I was looking into adding a parameter to target_detach, and was
wondering what the args parameter was. It seems like in the distant
past, it was possible to specify a signal number when detaching. That
signal was injected in the process before it was detached. There is an
example of code handling this in linux_nat_detach. With today's GDB, I
can't get this to work. Doing "detach 15" (15 == SIGTERM) doesn't work,
because detach is a prefix command and doesn't recognize the sub-command
15. Doing "detach inferiors 15" doesn't work because it expects a list
of inferior id to detach. Therefore, I don't think there's a way of
invoking detach_command with a non-NULL args. I also didn't find any
documentation related to this feature.
I assume that this feature stopped working when detach was made a prefix
command, which is in f73adfeb8bae36885e6ea248d12223ab0d5eb9cb (sorry,
there's no commit title) from 2006. Given that this feature was broken
for such a long time and we haven't heard anything (AFAIK, I did not
find any related bug), I think it's safe to remove it, as well as the
args parameter to target_detach. If someone wants to re-introduce it, I
would suggest rethinking the user interface, and in particular would
suggest using signal name instead of numbers.
I tried to fix all the impacted code, but I might have forgotten some
spots. It shouldn't be hard to fix if that's the case. I also couldn't
build-test everything I changed, especially the nto and solaris stuff.

This is the previously mentioned patch to get rid of
unstructured/ioctl-based procfs support in procfs.c. Given that support
for structured procfs was introduced in Solaris 2.6 back in 1997 and
we're just removing support for Solaris < 10, there's no point in
carrying that baggage (and tons of support for IRIX and OSF/1 as well)
around any longer.
Most of the patch should be straightforward (removing support for
!NEW_PROC_API, non-Solaris OSes and pre-Solaris 10 quirks).
Only a few points need explanations:
* <sys/syscall.h> was already included unconditionally in most places,
so there's no need to have guards in a few remaining ones.
* configure.host already obsoletes i?86-*-sysv4.2, i?86-*-sysv5, so
NEW_PROC_API detection for those in configure.ac can go.
* I'm still including <sys/procfs.h> with #define _STRUCTURED_PROC 1.
Theoretically, it would be better to include <procfs.h> on Solaris
(which includes that define), but that breaks the build over
<procfs.h> vs. gdb's "procfs.h", and doesn't exist on Linux.
* I've regenerated syscall_table[] in proc-events.c with a small script
from Solaris 10, 11.3, 11.4 <sys/syscall.h>, so there should be no
traces of older Solaris versions and other OSes left.
* prsysent_t and DYNAMIC_SYSCALLS was only used for AIX 5, but AIX
doesn't use procfs.c any longer, so all related code can go.
The patch was generated with diff -w so one can easier see changes
without being distracted by simple reindentations.
So far, it has only been compiled and smoke-tested on
amd64-pc-solaris2.1[01], sparcv9-sun-solaris2.1[01], and
x86_64-pc-linux-gnu. Certainly needs more testing (Solaris 11.3
vs. 11.4, 32-bit gdb, testsuite once I've figured out what's wrong on
Solaris 10 etc.), but it's enough to get a first impression how much
cleanup is possible here.

This changes add_com to take a cmd_const_cfunc_ftype, and then fixes
up all the command implementations.
In most cases this is trivial.
In a couple of places I had to again introduce a temporary non-const
overload. These overloads will be removed when add_info is
constified.

This patches removes get_regcache_arch, and use regache->arch () instead.
The motivation of this change is that I am going to move some basic stuff
into a base class of regcache. I don't need to update "client" code
regcache->arch (). On the other hand, this patch shortens the code a
little bit.

I just tried to compile gdb trunk on Solaris 11.4 (formerly 12), and
failed for a couple of reasons:
*
In file included from /usr/include/python2.7/Python.h:128:0,

^
New in Solaris 11.4: <python2.7/ceval.h> uses a Studio-only #pragma.
I've disabled the warning in warnings.m4.
*

^
Since Solaris 11, vfork () is marked deprecated in <unistd.h>.
cf. vfork(2):
The vfork() and vforkx() functions are deprecated. Their sole legiti-
mate use as a prelude to an immediate call to a function from the exec
family can be achieved safely by posix_spawn(3C) or posix_spawnp(3C).
Again, I've disabled the warning.

With the changes below, I can build gdb on sparcv9-sun-solaris2.11 and
amd64-pc-solaris2.11 and a simple smoke test (gdb/gdb gdb/gdb) works.

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.

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.

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.

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:
<https://sourceware.org/ml/gdb-patches/2017-03/msg00191.html>

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.

Since callers are not supposed to free the string returned by these
methods, change the methods' signature to return const strings.

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.

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 */
^

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:
/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.

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.

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.

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.

+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.

This is a patch I extracted from Pedro's C++ branch. It contains the
most trivial enum fixes, where an integer type/value was used instead
of the appropriate enum type/value. It fixes many C++ errors, since
in C++ you can't mix integers and enums implicitely.
Regardless of the C++ conversion, I think this is a good cleanup to make
use of the appropriate enum types.
Regression-tested on native x86_64.

This commit does most of the mechanical removal. IOW, the easy part.
procfs.c isn't touched beyond removing a couple obvious bits that are
guarded by a couple macros defined in config/alpha/nm-osf3.h. Going
beyond that for procfs.c & co would be a harder excision that
potentially affects Solaris.
Some comments in the generic alpha code ABIs that may still be
relevant and I wouldn't know what to do with them. That can always be
done on a separate pass, preferably by someone who can test on alpha.
A couple other spots have references to OSF/Tru64 and related files
being removed, but it felt like removing them would make things worse,
not better. We can revisit those when we next need to touch that
code.
I didn't remove a reference to osf in testsuite/lib/future.exp, as I
believe that code is imported from DejaGNU.
Built and tested on x86_64 Fedora 20, with --enable-targets=all.

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.

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.
