9c80ecd646 gdbserver: use std::list for all_threads
Remove the usage of inferior_list for the all_threads list in
gdbserver.  The entry field in thread_info is removed, and replaced by a
simple ptid field.

I added some functions to iterate (for_each_thread) and find threads
(find_thread).  However, changing all the users of find_inferior & co to
use these new functions would have made the patch way too big.  So I
opted instead to make find_inferior & co some shims, so that the
existing code only needs to be updated minimally.  We can then update
the existing code to use the new functions incrementally (I've started
to do the work, but I'll post it afterwards, see [1] if you want a peek).

This patch has been built-tested on all relevant platforms, except
lynx.  I also regtested using the native-gdbserver and
native-extended-gdbserver boards on x86.

229d26fc9e Add enum for result of fast_tracepoint_collecting
I got confused by the result value of fast_tracepoint_collecting, while
it sounds like it would return true/false (whether the thread is
collecting or not), it actually returns:

  0: not collecting
  1: in the jump pad, before the relocated instruction
  2: in the jump pad, at or after the relocated instruction

To avoid confusion, I think it would be nice to make it return an enum.
If you can help find a shorter but still relavant name, it would be
awesome.  Otherwise, we'll go with that, fast_tpoint_collect_result,
which is at least consistent with the existing
fast_tpoint_collect_status.

gdb/gdbserver/ChangeLog:

	* tracepoint.h (enum class fast_tpoint_collect_result): New
	enumeration.

dcb07cfa15 gdb: Use C++11 std::chrono
This patch fixes a few problems with GDB's time handling.

#1 - It avoids problems with gnulib's C++ namespace support

On MinGW, the struct timeval that should be passed to gnulib's
gettimeofday replacement is incompatible with libiberty's
timeval_sub/timeval_add.  That's because gnulib also replaces "struct
timeval" with its own definition, while libiberty expects the
system's.

E.g., in code like this:

  gettimeofday (&prompt_ended, NULL);
  timeval_sub (&prompt_delta, &prompt_ended, &prompt_started);
  timeval_add (&prompt_for_continue_wait_time,
               &prompt_for_continue_wait_time, &prompt_delta);

That's currently handled in gdb by not using gnulib's gettimeofday at
all (see common/gdb_sys_time.h), but that #undef hack won't work with
if/when we enable gnulib's C++ namespace support, because that mode
adds compile time warnings for uses of ::gettimeofday, which are hard
errors with -Werror.

#2 - But there's an elephant in the room: gettimeofday is not monotonic...

We're using it to:

  a) check how long functions take, for performance analysis
  b) compute when in the future to fire events in the event-loop
  c) print debug timestamps

But that's exactly what gettimeofday is NOT meant for.  Straight from
the man page:

~~~
       The time returned by gettimeofday() is affected by
       discontinuous jumps in the system time (e.g., if the system
       administrator manually changes the system time).  If you need a
       monotonically increasing clock, see clock_gettime(2).
~~~

std::chrono (part of the C++11 standard library) has a monotonic clock
exactly for such purposes (std::chrono::steady_clock).  This commit
switches to use that instead of gettimeofday, fixing all the issues
mentioned above.

35fd2deb69 Fix write endianness/size problem for fast tracepoint enabled flag
I am sending this fix on behalf of Par Olsson, as a follow-up of this
one:

https://www.sourceware.org/ml/gdb-patches/2015-10/msg00196.html

This problem is exposed when enabling/disabling fast tracepoints on big
endian machines.  The flag is defined as an int8_t, but is written from
gdbserver as an integer (usually 32 bits).  When the agent code reads it
as an int8_t, it only considers the most significant byte, which is
always 0.

Also, we were writing 32 bits in an 8 bits field, so the write would
overflow, but since the following bytes are padding (the next field is
an uint64_t), it luckily didn't cause any issue on little endian
systems.

The fix was originally tested on ARM big endian systems, but I don't
have access to such a system.  However, thanks to Marcin's PowerPC fast
tracepoint patches and gcc110 (big endian Power7) on the gcc compile
farm, I was able to reproduce the problem, test the fix and write a
test (the following patch).

a13c46966d IPA: Add alloc_jump_pad_buffer target hook.
Targets may have various requirements on the required location of the jump
pad area.  Currently IPA allocates it at the lowest possible address,
so that it is reachable by branches from the executable.  However, this
fails on powerpc, which has executable link address (0x10000000) much
larger than branch reach (+/- 32MiB).

This makes jump pad buffer allocation a target hook instead.  The current
implementations are as follows:

- i386 and s390: Branches can reach anywhere, so just mmap it.  This
  avoids the linear search dance.
- x86_64: Branches have +/-2GiB of reach, and executable is loaded low,
  so just call mmap with MAP_32BIT.  Likewise avoids the linear search.
- aarch64: Branches have +-128MiB of reach, executable loaded at 4MiB.
  Do a linear search from 4MiB-size downwards to page_size.
- s390x: Branches have +-4GiB of reach, executable loaded at 2GiB.
  Do like on aarch64.

1cda151268 gdbserver/IPA: Export some functions via global function pointers.
On powerpc64, qSymbol for a function returns the function code address,
and not the descriptor address.  Since we emit code calling gdb_collect
and some other functions, we need the descriptor (no way to know the
proper TOC address without it).  To get the descriptor address, make
global function pointer variables in the IPA pointing to the relevant
functions and read them instead of asking for them directly via qSymbol.

ae91f62539 [PR gdb/13808] gdb.trace: Pass tdesc selected in gdbserver to IPA.
If gdbserver and IPA are using different tdesc, they will disagree
about 'R' trace packet size.  This results in mangled traces.

To make sure they pick the same tdesc, gdbserver pokes the tdesc
(specified as an index in a target-specific list) into a global
variable in IPA.  In theory, IPA could find out the tdesc on its
own, but that may be complex (in particular, I don't know how to
tell whether we have LAST_BREAK on s390 without messing with ptrace),
and we'd have to duplicate the logic.

Tested on i386 and x86_64.  On i386, it fixes two FAILs in ftrace.exp.
On x86_64, these failures have been KFAILed - one of them works now,
but the other now fails due to an unrelated reason (ugh).

7cae9051ed gdbserver: Remove tracepoint_action ops.
This patch removes 'ops' in tracepoint, and uses helper functions to
call action handler instead.

The object layout of tracepoint_action may differ in gdbserver and
inferior depend on the alignment rule of target ABI, so gdbserver cannot
simply copy the object from its memory to inferior memory.

For example,

  struct collect_memory_action
  {
    struct tracepoint_action base;
    {
      #ifndef IN_PROCESS_AGENT
      const struct tracepoint_action_ops *ops;
      #if
  -   char type;
  | }
  | ULONGEST addr;
  | ULONGEST len;
  - int32_t basereg;
  };

and on PowerPC,

     Wihtout ops           with ops
      0   1   2   3         0   1   2   3
   0 |type| PADDING...    0 |ops-------------|
   4 .................    4 |type|PADDING....|
   8 |addr------------    8 |addr-------------
   c ----------------|    c -----------------|
  10 |len-------------   10 |len--------------
  14 ----------------|   14 -----------------|
  18 |basereg--------|   18 |basereg---------|

so we cannot directly copy the object.

In this patch, 'ops' is removed in order to make the objects identical.

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).

18fe412be4 [gdbserver] Remove unused max_jump_pad_size
This patch is to remove max_jump_pad_size which isn't used else where,
and it causes a recent gcc warning like this,

gdb/gdbserver/tracepoint.c:2920:18: error: 'max_jump_pad_size' defined but not used [-Werror=unused-const-variable]
 static const int max_jump_pad_size = 0x100;
                  ^
cc1: all warnings being treated as errors

This variable max_jump_pad_size wasn't used since it was added in 2010
by https://sourceware.org/ml/gdb-patches/2010-06/msg00002.html

d78908cff5 Fix argument to compiled_cond, and add cases for compiled-condition.
This patch fixes the argument passed to compiled_cond.  It should be
regs buffer instead of tracepoint_hit_ctx.  Test case is added as
well for testing compiled-cond.

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.

438e1e427e Prepare for gnulib update
After the last gnulib import (Dec 2012), gnulib upstream started
replacing mingw's 'struct timeval' with a version with 64-bit time_t,
for POSIX compliance:

 commit f8e84098084b3b53bc6943a5542af1f607ffd477
 Author: Bruno Haible <bruno@clisp.org>
 Date:   Sat Jan 28 18:12:10 2012 +0100
     sys_time: Override 'struct timeval' on some native Windows platforms.

See:

 https://lists.gnu.org/archive/html/bug-gnulib/2012-01/msg00372.html

However, that results in conflicts with native Winsock2's 'select':

select()'s argument
	http://sourceforge.net/p/mingw-w64/mailman/message/29610438/

... and libiberty's timeval-utils.h timeval_add/timeval_sub, at the
least.

We don't really need the POSIX compliance, so this patch prepares us
to simply not use gnulib's 'struct timeval' replacement once a more
recent gnulib is imported, thus preserving the current behavior, by
adding a sys/time.h wrapper header that undefs gnulib's replacements,
and including that everywhere instead.

The SIZE -> OSIZE change is necessary because newer gnulib's
sys/time.h also includes windows.h/winsock2.h, which defines a
conflicting SIZE symbol.

Cross build-tested mingw-w64 32-bit and 64-bit.
Regtested on x86_64 Fedora 20.

dc06243f6f Remove redundant include directives.
stdint.h was added to common-defs.h some months ago and should
no longer be included directly by any file.

gdb_assert.h was added to common-defs.h nearly a year ago, but
three includes have crept in since then.

This commit removes all such redundant include directives.

3c14e5a39b Make functions and variables exported by the IPA be extern "C"
Functions and variables that are exported by the IPA DSO (that
GDBserver needs to look up) should have "C" mangling, thus be declared
with extern "C".

Function and variable declarations need the extern "C" marker, but
variable definitions can't be marked extern, so the patch splits
IP_AGENT_EXPORT into three.

Building in C++ mode revealed that a few variables were missing
IP_AGENT_EXPORT, thus the IPA has been broken when stripped, even in C
mode...  So this ends being a bug fix as well.

b05ec7a53f gdbserver: Fix crash when QTinit is handled with no inferior process attached
When gdbserver is called with --multi and attach has not been called yet
and tstart is called on the gdb client, gdbserver would crash.
This patch fixes gdbserver so that it returns E01 to the gdb client.

Also this patch adds a testcase to verify this bug named no-attach-trace.exp

582511be69 [gdbserver] linux-low.c: better starvation avoidance, handle non-stop mode too
This patch applies the same starvation avoidance improvements of the
previous patch to the Linux gdbserver side.

Without this, the test added by the following commit
(gdb.threads/non-stop-fair-events.exp) always fails with time outs.

0bfdf32fa1 Rename current_inferior as current_thread in gdbserver
GDB has a function named "current_inferior" and gdbserver has a global
variable named "current_inferior", but the two are not equivalent;
indeed, gdbserver does not have any real equivalent of what GDB calls
an inferior.  What gdbserver's "current_inferior" is actually pointing
to is a structure describing the current thread.  This commit renames
current_inferior as current_thread in gdbserver to clarify this.  It
also renames the function "set_desired_inferior" to "set_desired_thread"
and renames various local variables from foo_inferior to foo_thread.

9c3d65319a move some rsp bits into rsp-low.h
This moves various low-level remote serial protocol bits into
common/rsp-low.[ch].

This is as close to a pure move as possible.  There are some
redundancies remaining but those will be dealt with in a subsequent
patch.

Note that the two variants of remote_escape_output disagreed on the
treatment of "*".  On the theory that quoting cannot hurt but the
absence possibly can, I chose the gdbserver variant to be the
canonical one.
