ac7936dfd0 s/get_regcache_arch (regcache)/regcache->arch ()/g 
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.

2090129c36 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.

7c5ded6a00 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.

b67aeab02c Remove lwp -> pid conversion in linux_nat_xfer_partial 
The linux_nat_xfer_partial does a conversion of inferior_ptid: if it's
an LWP (ptid::lwp != 0), it builds a new ptid with the lwp as
the pid and assigns that temporarily to inferior_ptid.  For example, if
inferior_ptid is:

  { .pid = 1234, .lwp = 1235 }

it will assign this to inferior_ptid for the duration of the call:

  { .pid = 1235, .lwp = 0 }

Instead of doing this, this patch teaches the inf-ptrace implementation
of xfer_partial to deal with ptids representing lwps by using
get_ptrace_pid.

Also, in linux_proc_xfer_spu and linux_proc_xfer_partial, we use ptid_get_lwp
instead of ptid_get_pid.  While not strictly necessary, since the content of
/proc/<pid> and /proc/<lwp> should be the same, it's a bit safer, because:

- some files under /proc/<pid>/ may not work if the <pid> thread is
  running, just like ptrace requires a stopped thread.  The current
  thread's lwp id is more likely to be in the necessary state (stopped).

- if the leader (<pid>) had exited and is thus now zombie, then several
  files under "/proc/<pid>" won't work, while they will if you use
  "/proc/<lwp>".

The testsuite found no regression on native amd64 linux.

87c336f60e inf-ptrace: Do not stop memory transfers after a single word 
When inf_ptrace_xfer_partial performs a memory transfer via ptrace with
PT_READ_I, PT_WRITE_I (aka PTRACE_PEEKTEXT, PTRACE_POKETEXT), etc., then
it currently transfers at most one word.  This behavior yields degraded
performance, particularly if the caller has significant preparation work
for each invocation.  And indeed it has for writing, in
memory_xfer_partial in target.c, where all of the remaining data to be
transferred is copied to a temporary buffer each time, for breakpoint
shadow handling.  Thus large writes have quadratic runtime and can take
hours.

Note: On GNU/Linux targets GDB usually does not use
inf_ptrace_xfer_partial for large memory transfers, but attempts a single
read/write from/to /proc/<pid>/mem instead.  However, the kernel may
reject writes to /proc/<pid>/mem (such as kernels prior to 2.6.39), or
/proc may not be mounted.  In both cases GDB falls back to the ptrace
mechanism.

This patch fixes the performance issue by attempting to fulfill the whole
transfer request in inf_ptrace_xfer_partial, using a loop around the
ptrace call.

	PR gdb/21220
	* inf-ptrace.c (inf_ptrace_xfer_partial): In "case

0db8980cc0 PR gdb/16188: Verify PTRACE_TRACEME succeeded 
This patch fixes PR gdb/16188, which is about the fact that
fork_inferior doesn't verify the return value of the "traceme_fun"
callback.  On most targets, this callback is actually a wrapper to a
ptrace call that does a PTRACE_TRACEME on the forked GDB process that
will eventually become the inferior.

Thanks to Pedro, this second version of the patch is simpler and more
more logical.  Basically, two helper functions are added:
trace_start_error and trace_start_error_with_name.  The former can be
used when there is a customized error message to be printed to the
user.  The latter works like perror_with_name, so you just need to
pass the function that error'd.

Both helper functions mentioned above do basically the same thing:
print the error message to stderr and call _exit, properly terminating
the forked inferior.

Most of the patch takes care of guarding the necessary system calls
against errors on the "traceme_fun" callbacks.  It is not right to
call error on these situations, so I've replaced these calls with the
proper helper function call.

Regression-tested on BuildBot.

bc1e6c81d5 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.

ced2dffbf1 Fix failure to detach if process exits while detaching on Linux 
This commit fixes detaching on Linux when some thread exits the whole
thread group (process) just while we're detaching.

On Linux, a ptracer must detach from each LWP individually, with
PTRACE_DETACH.  Since PTRACE_DETACH sets the thread running free, if
one of the already-detached threads causes the whole thread group to
exit (e.g., simply calls exit), the kernel force-kills the other
threads in the group, making them zombie, just as we're still
detaching them.  Since PTRACE_DETACH against a zombie thread fails
with ESRCH, and gdb/gdbserver are not expecting this, the detach fails
with an error like: "Can't detach process: No such process.".

This patch detects this detach failure as normal, and instead of
erroring out, reaps the now-dead thread.

New test included, that exercises several different scenarios that
cause GDB/GDBserver to error out when it should not.

Tested on x86-64 GNU/Linux with {unix, native-gdbserver,
native-extended-gdbserver}

Note: without the previous fix, the "single-process + continue"
variant of the new test would fail with:

 (gdb) PASS: gdb.threads/process-dies-while-detaching.exp: single-process: continue: watchpoint: switch to parent

0f48b75707 Factor out "Detaching from program" message printing 
Several targets have a copy of the same code that prints

 "Detaching from program ..."

in their target_detach implementation.  Factor that out to a common
function.

(For now, I left the couple targets that print this a bit differently
alone.  Maybe this could be further pulled out into infcmd.c.  If we
did that, and those targets want to continue printing differently,
this new function could be converted to a target method.)

94309df7aa Use LWP IDs with ptrace register requests on FreeBSD. 
This allows gdb to fetch per-thread registers for multi-threaded FreeBSD
processes.

Export get_ptrace_pid() from inf-ptrace.c and use it to determine the PID
to pass to ptrace in pan-BSD native targets.  NetBSD and OpenBSD also accept
LWP IDs for ptrace requests to fetch per-thread state.

4397c913d5 Replace long int * cast with PTRACE_TYPE_RET * 
These casts uses the typedef target type (long int *) instead of the
typedef name.  This was a little mistake in one of the big C++ cast
patches.

224c3ddb89 Add casts to memory allocation related calls 
Most allocation functions (if not all) return a void* pointing to the
allocated memory.  In C++, we need to add an explicit cast when
assigning the result to a pointer to another type (which is the case
more often than not).

The content of this patch is taken from Pedro's branch, from commit
"(mostly) auto-generated patch to insert casts needed for C++".  I
validated that the changes make sense and manually reflowed the code to
make it respect the coding style.  I also found multiple places where I
could use XNEW/XNEWVEC/XRESIZEVEC/etc.

Thanks a lot to whoever did that automated script to insert casts, doing
it completely by hand would have taken a ridiculous amount of time.

Only files built on x86 with --enable-targets=all are modified.  This
means that all other -nat.c files are untouched and will have to be
dealt with later by using appropiate compilers.  Or maybe we can try to
build them with a regular g++ just to know where to add casts, I don't
know.

I built-tested this with --enable-targets=all and reg-tested.

Here's the changelog entry, which was not too bad to make despite the
size, thanks to David Malcom's script.  I fixed some bits by hand, but
there might be some wrong parts left (hopefully not).

 +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.

90ad5e1d4f Linux/ptrace: don't convert ptids when asking inf-ptrace layer to resume LWP 
Ref: https://sourceware.org/ml/gdb-patches/2015-03/msg00060.html

The record-btrace target can hit an assertion here:

 Breakpoint 1, record_btrace_fetch_registers (ops=0x974bfc0 <record_btrace_ops>,
     regcache=0x9a0a798, regno=8) at gdb/record-btrace.c:1202
 1202	  gdb_assert (tp != NULL);

 (gdb) p regcache->ptid
 $3 = {pid = 23856, lwp = 0, tid = 0}

The problem is that the linux-nat layer converts the ptid to a
single-process ptid before passing the request down to the inf-ptrace
layer, which loses information, and then record-btrace can't find the
corresponding thread in GDB's thread list:

 (gdb) bt

 ...

The fix is just to not lose information, and let the intact ptid reach
record-btrace.c.

d83ad864a2 Refactor native follow-fork. 
This patch reorganizes the code that implements follow-fork and
detach-on-fork in preparation for implementation of those features for the
extended-remote target.  The function linux-nat.c:linux_child_follow_fork
contained target-independent code mixed in with target-dependent code.  The
target-independent pieces need to be accessible for the host-side
implementation of follow-fork for extended-remote Linux targets.

The changes are fairly mechanical.  A new routine, follow_fork_inferior,
is implemented in infrun.c, containing those parts of
linux_child_follow_fork that manage inferiors and the inferior list.  The
parts of linux_child_follow_fork that deal with LWPs and target-specifics
were left in-place.  Although the order of some operations was changed, the
resulting functionality was not.

Modifications were made to the other native target follow-fork functions,
inf_ttrace_follow_fork and inf_ptrace_follow_fork, that should allow them
to work with follow_fork_inferior.  Some other adjustments were necessary
in inf-ttrace.c.  The changes to inf-ttrace.c and inf-ptrace.c were not
tested.

gdb/ChangeLog:

	* inf-ptrace.c (inf_ptrace_follow_fork): Remove target-independent
	code so as to work with follow_fork_inferior.
	* inf-ttrace.c (inf_ttrace_follow_fork): Ditto.

	inferior away from the parent.

	(follow_inferior_reset_breakpoints): Make function static.

	* linux-nat.c (linux_child_follow_fork): Move target-independent

c0939df1ce constify to_attach 
This constifies the "args" argument to the target_ops to_attach
method.

I updated all instances of the method.  I could not compile all of
them but I hand-inspected them.  In all cases either the argument is
ignored, or it is passed to parse_pid_to_attach.  (linux-nat does some
extra stuff, but that one I built...)

If you want to try it on your host of choice, please do so.

The code in parse_pid_to_attach seems a little bogus to me.  If there
is a platform with a broken strtoul, we have better methods for fixing
the issue now.  However, I left the code as is since it is clearly ok
to do so.

Built and regtested on x86-64 Fedora 20.

c1ee2fb3cb Native targets: Add inf-child.c:inf_child_mourn_inferior and use it. 
Most ports do the same thing in the tail of their mourn routine - call
generic_mourn_inferior+inf_child_maybe_unpush_target.

This factors that out to a convenience function.  More could be done,
but this converts only the really obvious ones.

Tested by building GDB on x86_64 Fedora 20, mingw32 and djgpp.  The
rest is untested, but I think a patch can't get more obvious.

6a3cb8e88a 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.

493443a47f FIX EOF detection in PT_IO-based to_xfer_partial implementation. 
At least on OpenBSD PT_IO/PIOD_READ_AUXV can return sucessfully without
transferring any bytes.  Arguably a kernel bug, but interpreting this as EOF
seems sensible.

        * inf-ptrace.c (inf_ptrace_xfer_partial): Return TARGET_XFER_EOF
        if a PT_IO ptrace request returns sucessfully but indicates that 0

9b409511d0 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.

0e9f083f4c remove gdb_string.h 
This removes gdb_string.h.  This patch is purely mechanical.  I
created it by running the two commands:

    git rm common/gdb_string.h
    perl -pi -e's/"gdb_string.h"/<string.h>/;'  *.[chyl] */*.[chyl]

52554a0e32 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.

98882a2651 Make STARTUP_WITH_SHELL a runtime toggle -- add new "set/show startup-with-shell" option. 
Occasionaly we hear about people having problems with GDB not being
able to start programs (with "run"/"start").  GDB spawns a shell to
start the program, and most often, it'll be the case that the problem
is actually with the user's shell setup.

GDB has code to disable the use of the shell to start programs.
That's the STARTUP_WITH_SHELL macro that native targets could set to 0
in their nm.h file (though no target actually uses it nowadays).

This patch makes that setting a run-time knob instead.  This will be
useful to quickly diagnose such shell issues, and might also come in
handy at other times (such as when debugging the shell itself, if you
don't have a different shell handy).

25f4350049 cleanup fixes for inf-ptrace.c 
This is one of the stylistic patches.  The code here in inf-ptrace.c
is not incorrect, but it is in a style that the cleanup checker cannot
handle.  This patch changes it to a simpler style, following the usual
method of introducing an unconditional "outer" cleanup.

	* inf-ptrace.c (inf_ptrace_create_inferior): Unconditionally
	call discard_cleanups.
	(inf_ptrace_attach): Likewise.

28e7fd6234 Update years in copyright notice for the GDB files. 
Two modifications:
  1. The addition of 2013 to the copyright year range for every file;
  2. The use of a single year range, instead of potentially multiple
     year ranges, as approved by the FSF.
