4de283e4b5 Revert the header-sorting patch
Andreas Schwab and John Baldwin pointed out some bugs in the header
sorting patch; and I noticed that the output was not correct when
limited to a subset of files (a bug in my script).

So, I'm reverting the patch.  I may try again after fixing the issues
pointed out.

d55e5aa6b2 Sort includes for files gdb/[a-f]*.[chyl].
This patch sorts the include files for the files [a-f]*.[chyl].
The patch was written by a script.

Tested by the buildbot.

I will follow up with patches to sort the remaining files, by sorting
a subset, testing them, and then checking them in.

0f83012ea0 Add linux_get_hwcap
Tidy up calls to read HWCAP (and HWCAP2) by adding common functions,
removing the PPC and AArch64 specific versions.

The only function difference is in aarch64_linux_core_read_description - if
the hwcap read fails it now return a valid description instead of nullptr.

42a4f53d2b Update copyright year range in all GDB files.
This commit applies all changes made after running the gdb/copyright.py
script.

Note that one file was flagged by the script, due to an invalid
copyright header
(gdb/unittests/basic_string_view/element_access/char/empty.cc).
As the file was copied from GCC's libstdc++-v3 testsuite, this commit
leaves this file untouched for the time being; a patch to fix the header
was sent to gcc-patches first.

	Update copyright year range in all GDB files.

a616bb9450 Split size in regset section iterators
In the existing code, when using the regset section iteration functions, the
size parameter is used in different ways.

With collect, size is used to create the buffer in which to write the regset.
(see linux-tdep.c::linux_collect_regset_section_cb).

With supply, size is used to confirm the existing regset is the correct size.
If REGSET_VARIABLE_SIZE is set then the regset can be bigger than size.
Effectively, size is the minimum possible size of the regset.
(see corelow.c::get_core_register_section).

There are currently no targets with both REGSET_VARIABLE_SIZE and a collect
function.
In SVE, a corefile can contain one of two formats after the header, both of
which are different sizes. However, when writing a core file, we always want
to write out the full bigger size.

To allow support of collects for REGSET_VARIABLE_SIZE we need two sizes.
This is done by adding supply_size and collect_size.

00431a78b2 Use thread_info and inferior pointers more throughout
This is more preparation bits for multi-target support.

In a multi-target scenario, we need to address the case of different
processes/threads running on different targets that happen to have the
same PID/PTID.  E.g., we can have both process 123 in target 1, and
process 123 in target 2, while they're in reality different processes
running on different machines.  Or maybe we've loaded multiple
instances of the same core file.  Etc.

To address this, in my WIP multi-target branch, threads and processes
are uniquely identified by the (process_stratum target_ops *, ptid_t)
and (process_stratum target_ops *, pid) tuples respectively.  I.e.,
each process_stratum instance has its own thread/process number space.

As you can imagine, that requires passing around target_ops * pointers
in a number of functions where we're currently passing only a ptid_t
or an int.  E.g., when we look up a thread_info object by ptid_t in
find_thread_ptid, the ptid_t alone isn't sufficient.

In many cases though, we already have the thread_info or inferior
pointer handy, but we "lose" it somewhere along the call stack, only
to look it up again by ptid_t/pid.  Since thread_info or inferior
objects know their parent target, if we pass around thread_info or
inferior pointers when possible, we avoid having to add extra
target_ops parameters to many functions, and also, we eliminate a
number of by ptid_t/int lookups.

So that's what this patch does.  In a bit more detail:

- Changes a number of functions and methods to take a thread_info or
  inferior pointer instead of a ptid_t or int parameter.

- Changes a number of structure fields from ptid_t/int to inferior or
  thread_info pointers.

- Uses the inferior_thread() function whenever possible instead of
  inferior_ptid.

- Uses thread_info pointers directly when possible instead of the
  is_running/is_stopped etc. routines that require a lookup.

- A number of functions are eliminated along the way, such as:

  int valid_gdb_inferior_id (int num);
  int pid_to_gdb_inferior_id (int pid);
  int gdb_inferior_id_to_pid (int num);
  int in_inferior_list (int pid);

- A few structures and places hold a thread_info pointer across
  inferior execution, so now they take a strong reference to the
  (refcounted) thread_info object to avoid the thread_info pointer
  getting stale.  This is done in enable_thread_stack_temporaries and
  in the infcall.c code.

- Related, there's a spot in infcall.c where using a RAII object to
  handle the refcount would be handy, so a gdb::ref_ptr specialization
  for thread_info is added (thread_info_ref, in gdbthread.h), along
  with a gdb_ref_ptr policy that works for all refcounted_object types
  (in common/refcounted-object.h).

454dafbdf2 Introduce gdb_breakpoint_up
This introduces gdb_breakpoint_up, a unique_ptr typedef that owns a
breakpoint.  It then changes set_momentary_breakpoint to return a
gdb_breakpoint_up and fixes up the fallout.  This then allows the
removal of make_cleanup_delete_breakpoint.

Once breakpoints are fully C++-ified, this typedef can be removed in
favor of a plain std::unique_ptr.

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.

cfba98720f Create a displaced_step_closure class hierarchy
displaced_step_closure is a type defined in multiple -tdep.c files.
Trying to xfree it from the common code (infrun.c) is a problem when we
try to poison xfree for non-POD types.  Because there can be multiple of
these types in the same build, this patch makes a hierarchy of classes
with a virtual destructor.  When the common code deletes the object
through a displaced_step_closure pointer, it will invoke the right
destructor.

The amd64 used a last-member array with a variable size.  That doesn't
work with new, so I changed it for an std::vector.  Other architectures
which used a simple byte buffer as a closure now use a shared
buf_displaced_step_closure, a closure type that only contains a
gdb::byte_vector.

Reg-tested on the buildbot.

	* infrun.h: Include common/byte-vector.h.
	(struct displaced_step_closure): New struct.
	(struct buf_displaced_step_closure): New struct.

1841ee5d03 Clean up includes of doublest.h and floatformat.h
As a first small step to getting rid of doublest.h, this patch removes the
include of "floatformat.h" in "doublest.h".  This is actually not needed
for the file itself.  A few source files now need to include "floatformat.h"
directly, since they got it indirectly via "doublest.h" and still need it.

In reviewing which files need it, I found a number of files that include
"floatformat.h" directly without actually needing it at all.  Similarly,
a number of files include "doublest.h" without needing it.  I've also
removed those unnecessary include statements.

f1735a53a6 Rename _const functions to use overloading instead
This renames a few functions -- skip_spaces_const,
skip_to_space_const, get_number_const, extract_arg_const -- to drop
the "_const" suffix and instead rely on overloading.

This makes future const fixes simpler by reducing the number of lines
that must be changed.  I think it is also not any less clear, as all
these functions have the same interface as their non-const versions by
design.  Furthermore there's an example of using an overload in-tree
already, namely check_for_argument.

This patch was largely created using some perl one-liners; then a few
fixes were applied by hand.

6d45d4b42b gdbarch: Remove displaced_step_free_closure
The displaced_step_free_closure gdbarch hook allows architectures to
free data they might have allocated to complete a displaced step.
However, all architectures using that hook use the
simple_displaced_step_free_closure provided in arch-utils.{c,h}, which
does a simple xfree.  We can remove it and do an xfree directly instead
of calling the hook.

gdb/ChangeLog:

	* gdbarch.sh (displaced_step_free_closure): Remove.
	* gdbarch.h, gdbarch.c: Re-generate.
	* aarch64-linux-tdep.c (aarch64_linux_init_abi): Don't set

ed443b61e1 [ARM] Fixup PC in software single step
When I exercise GDBserver software single step, I see the following
error, which has been already handled by GDB properly.

In GDBserver log, we can see, GDBserver tries to single step instruction
on 0xb6e0a6e4, and destination address is 0xffff0fe0,

 stop pc is 0xb6e0a6e4
 Writing f001f0e7 to 0xffff0fe0 in process 7132
 Failed to insert breakpoint at 0xffff0fe0 (Input/output error).
 Failed to insert breakpoint at 0xffff0fe0 (-1).

(gdb) disassemble __aeabi_read_tp,+8
Dump of assembler code from 0xb6e0a6e0 to 0xb6e0a6e8:
   0xb6e0a6e0 <__aeabi_read_tp+0>:	mvn	r0, #61440	; 0xf000
   0xb6e0a6e4 <__aeabi_read_tp+4>:	sub	pc, r0, #31

however, it fails inserting breakpoint there.  This problem has already
fixed by GDB, see comments in arm-linux-tdep.c:arm_linux_software_single_step

      /* The Linux kernel offers some user-mode helpers in a high page.  We can
	 not read this page (as of 2.6.23), and even if we could then we
	 couldn't set breakpoints in it, and even if we could then the atomic
	 operations would fail when interrupted.  They are all called as
	 functions and return to the address in LR, so step to there
	 instead.  */

so we need to do the same thing in GDB side as well.  This patch adds
a new field fixup in arm_get_next_pcs_ops, so that we can fix up PC
for arm-linux target.  In this way, both GDB and GDBserver can single
step instructions going to kernel helpers.

(gdb) FAIL: gdb.base/sigstep.exp: continue to handler, si+advance in handler, step from handler: leave handler

in my test setting, program is compiled in arm mode, but the glibc
is built in thumb mode, so when we do 'step' to step over syscall
instruction svc for SIGRETURN, GDB should set breakpoint for arm mode
in the program, even though the current program in glibc is in thumb
mode.  Current GDB doesn't consider the case that the mode of program
SIGRETURN goes to can be different from current program mode.

In fact, GDB has taken care of this arm/thumb mode changes already,
see

/* Copy the value of next pc of sigreturn and rt_sigrturn into PC,
   return 1.  In addition, set IS_THUMB depending on whether we
   will return to ARM or Thumb code.  Return 0 if it is not a

static int

the IS_THUMB setting is lost, so it is a regression.

Field syscall_next_pc in struct gdbarch_tdep was to calculate the

is set to arm_linux_syscall_next_pc, to do linux specific things.
However, after we have struct arm_get_next_pcs_ops, we can do the

field arm_thumb2_breakpoint is only used in a null check in
thumb_get_next_pcs_raw, so I wonder why do need to pass thumb2_breakpoint
to arm_gdbserver_get_next_pcs.

thumb2_breakpoint was added by Daniel Jacobowitz in order to support
single-step IT block
https://sourceware.org/ml/gdb-patches/2010-01/msg00624.html  the logic
there was if we have 32-bit thumb-2 breakpoint defined, we can safely
single-step IT block, otherwise, we can't.  Daniel didn't want to use
16-bit thumb BKPT instruction, because it triggers even on instruction
which should be executed.  Secondly, using 16-bit thumb illegal
instruction on top of 32-bit thumb instruction may break the meaning of
original IT blocks, because the other 16-bit can be regarded as an
instruction.  See more explanations from Daniel's kernel patch
http://www.spinics.net/lists/arm-kernel/msg80476.html

Let us back to this patch, GDB/GDBserver can safely single step
IT block if thumb2_breakpoint is defined, but the single step logic
doesn't have to know the thumb-2 breakpoint instruction.  Only
breakpoint insertion mechanism decides to use which breakpoint
instruction.  In the software single step code, instead of pass
thumb2_breakpoint, we can pass a boolean variable
has_thumb2_breakpoint indicate whether the target has thumb-2
breakpoint defined, which is equivalent to the original code.

Regression tested on arm-linux.  No regression.

d9311bfaf5 Support software single step on ARM in GDBServer
This patch teaches GDBServer how to software single step on ARM
linux by sharing code with GDB.

The arm_get_next_pcs function in GDB is now shared with GDBServer.  So
that GDBServer can use the function to return the possible addresses of
the next PC.

A proper shared context was also needed so that we could share the code,
this context is described in the arm_get_next_pcs structure.

d0e59a6888 Refactor arm_software_single_step to use regcache
This patch is in preparation for software single step support on ARM in
GDBServer. It refactors arm_*_software_single_step and sub-functions to
use regcache instead of frame to access registers so that the code can be
shared more easily between GDB and GDBServer.

Note also that since the intention is at some point to get rid of frame
completely in that function, memory reads have also been replaced by
read_memory_unsigned_integer rather than get_frame_memory_unsigned.

No regressions, tested on ubuntu 14.04 ARMv7 and x86.

9a3c826307 Add some more casts (1/2)
Note: I needed to split this patch in two, otherwise it's too big for
the mailing list.

This patch adds explicit casts to situations where a void pointer is
assigned to a pointer to the "real" type.  Building in C++ mode requires
those assignments to use an explicit cast.  This includes, for example:

 - callback arguments (cleanups, comparison functions, ...)
 - data attached to some object (objfile, program space, etc) in the form
   of a void pointer
 - "user data" passed to some function

This patch comes from the commit "(mostly) auto-generated patch to insert
casts needed for C++", taken from Pedro's C++ branch.

Only files built on x86 with --enable-targets=all are modified, so the
native files for other arches will need to be dealt with separately.

I built-tested this with --enable-targets=all and reg-tested.  To my
surprise, a test case (selftest.exp) had to be adjusted.

Here's the ChangeLog entry.  Again, this was relatively quick to make
despite the length, thanks to David Malcom's script, although I don't
believe it's very useful information in that particular case...

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).

750ce8d1ca Support single step by arch or target
Nowadays, GDB only knows whether architecture supports hardware single
step or software single step (through gdbarch hook software_single_step),
and for a given instruction or instruction sequence, GDB knows how to
do single step (hardware or software).  However, GDB doesn't know whether
the target supports hardware single step.  It is possible that the
architecture doesn't support hardware single step, such as arm, but
the target supports, such as simulator.  This was discussed in this
thread https://www.sourceware.org/ml/gdb/2009-12/msg00033.html before.

I encounter this problem for aarch64 multi-arch support.  When aarch64
debugs arm program, gdbarch is arm, so software single step is still
used.  However, the underneath linux kernel does support hardware
single step, so IWBN to use it.

This patch is to add a new target_ops hook to_can_do_single_step, and
only use it in arm_linux_software_single_step to decide whether or not
to use hardware single step.  On the native aarch64 linux target, 1 is
returned.  On other targets, -1 is returned.  On the remote target, if
the target supports s and S actions in the vCont? reply, then target
can do single step.  However,  old GDBserver will send s and S in the
reply to vCont?, which will confuse new GDB.  For example, old GDBserver
on arm-linux will send s and S in the reply to vCont?, but it doesn't
support hardware single step.  On the other hand, new GDBserver, on
arm-linux for example, will not send s and S in the reply to vCont?,
but old GDB thinks it doesn't support vCont packet at all.  In order
to address this problem, I add a new qSupported feature vContSupported,
which indicates GDB wants to know the supported actions in the reply
to vCont?, and qSupported response contains vContSupported if the
stub is able tell supported vCont actions in the reply of vCont?.

If the patched GDB talks with patched GDBserver on x86, the RSP traffic
is like this:

 -> $qSupported:...+;vContSupported+
 <- ...+;vContSupported+
 ...
 -> $vCont?
 <- vCont;c;C;t;s;S;r

then, GDB knows the stub can do single step, and may stop using software
single step even the architecture doesn't support hardware single step.

If the patched GDB talks with patched GDBserver on arm, the last vCont?
reply will become:

 <- vCont;c;C;t

GDB thinks the target doesn't support single step, so it will use software
single step.

If the patched GDB talks with unpatched GDBserver, the RSP traffic is like
this:

 -> $qSupported:...+;vContSupported+
 <- ...+
 ...
 -> $vCont?
 <- vCont;c;C;t;s;S;r

although GDBserver returns s and S, GDB still thinks GDBserver may not
support single step because it doesn't support vContSupported.

If the unpatched GDB talks with patched GDBserver on x86, the RSP traffic
is like:

 -> $qSupported:...+;
 <- ...+;vContSupported+
 ...
 -> $vCont?
 <- vCont;c;C;t;s;S;r

Since GDB doesn't sent vContSupported in the qSupported feature, GDBserver
sends s and S regardless of the support of hardware single step.

8d7493201c 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.

f486487f55 Mostly trivial enum fixes
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.

5cd867b414 Call set_gdbarch_get_siginfo_type in linux_init_abi
linux_get_siginfo_type is installed to many linux gdbarch.  This patch
is to move this to a common area linux-tdep.c:linux_init_abi, so that
linux_get_siginfo_type is installed to every linux gdbarch.  If some
linux gdbarch needs its own version, please override it in
$ARCH_linux_init_abi.  In the testsuite, we enable siginfo related
tests for all linux targets.
