The makefile rule i386-avx512.c is to generate i386-avx512.c, but it
is written to i386-avx.c by mistake. This patch is to fix this typo.

* Makefile.in (i386-avx512.c): Fix the typo of generated file
name.
This patch adds support for the Intel(R) Advanced Vector
Extensions 512 (Intel(R) AVX-512) registers. Native and remote
debugging are covered by this patch.
Intel(R) AVX-512 is an extension to AVX to support 512-bit wide
SIMD registers in 64-bit mode (XMM0-XMM31, YMM0-YMM31, ZMM0-ZMM31).
The number of available registers in 32-bit mode is still 8
(XMM0-7, YMM0-7, ZMM0-7). The lower 256-bits of the ZMM registers
are aliased to the respective 256-bit YMM registers. The lower
128-bits are aliased to the respective 128-bit XMM registers.
There are also 8 new, dedicated mask registers (K0-K7) in both 32-bit
mode and 64-bit mode.

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.

This is the gdbserver-equivalent of the change made in GDB to handle
the case, in x64 windows version 2012, where the kernel produces
a LOAD_DLL_DEBUG_EVENT where the name of the associated DLL cannot
be determined at that time, and thus has to be processed later.
The visible symptom is that ntdll.dll is missing from the list of
shared libraries known to be mapped by the inferior, with other
side-effects such as failure to unwind through code provided by
that DLL (such as exception handling routines).

break the build.

This factors --enable-libmcheck related bits from GDB's configure.ac
and makes GDBserver use them too. Specifically, the 'development'
global is moved to a separate script to it can be sourced by both GDB
and GDBserver, and the --enable-libmcheck/--disable-libmcheck bits
proper are moved to a new m4 file.
I started out by defining 'development' in the m4 file, but in the end
decided against it, as a separate script has the advantage that
changing it in release branches does not require regenerating
configure, unlike today.
I had also started out by making the new GDB_AC_LIBMCHECK itself
handle the yes/no default fallback depending on release/developement,
but since I had split out 'development' to a separate script, and, GDB
needs the python checks anyway (hence we'd need to do the python
checks in gdb's configure.ac, and pass in a 'default lmcheck yes/no'
parameter to GDB_AC_LIBMCHECK anyway), I ended up keeping
GDB_AC_LIBMCHECK isolated from the 'development' global. IOW, it's
the caller's business to handle it.
Tested on x86_64 Fedora 17. Built GDB and GDBserver with and without
--enable-libmcheck, and observed --enable-libmcheck overrides the
disablement of -lmcheck caused by python supporting threads, and that
GDBserver links with -lmcheck when expected. Also observed that
changing the 'development' global, and issuing "make" triggers a
relink, and '-lmcheck' is included or not from the link accordingly.

Right now there are two nightly commits to update a file in the tree
with the current date. One commit is for BFD, one is for gdb.
It seems unnecessary to me to do this twice. We can make do with a
single such commit.
This patch changes gdb in a minimal way to reuse the BFD date -- it
extracts it from bfd/version.h and changes version.in to use the
placeholder string "DATE" for those times when a date is wanted.
I propose removing the cron job that updates the version on trunk, and
then check in this patch.
For release branches, we can keep the cron job, but just tell it to
rewrite bfd/version.h. I believe this is a simple change in the
crontab -- the script will work just fine on this file.
This also moves version.in and version.h into common/, to reflect
their shared status; and updates gdbserver to use version.h besides.
* common/create-version.sh: New file.
* Makefile.in (version.c): Use bfd/version.h, common/version.in,
create-version.sh.
(HFILES_NO_SRCDIR): Use common/version.h.
* version.in: Move to ...
* common/version.in: ... here. Replace date with "DATE".
* version.h: Move to ...
* common/version.h: ... here.
gdbserver:
* Makefile.in (version.c): Use bfd/version.h, common/version.in,
create-version.sh.
(version.o): Remove.
* gdbreplay.c: Include version.h.
(version, host_name): Don't declare.
* server.h: Include version.h.
(version, host_name): Don't declare.
doc:
* Makefile.in (POD2MAN1, POD2MAN5): Use version.subst.
(GDBvn.texi): Use version.subst.
(version.subst): New target.
(mostlyclean): Remove version.subst.
This patch makes GDBserver support multi-process + biarch.
Currently, if you're debugging more than one process at once with a
single gdbserver (in extended-remote mode), then all processes must
have the same architecture (e.g., 64-bit vs 32-bit). Otherwise, you
see this:

... etc, etc ...
Even though the process was running a 32-bit program, GDBserver sent
back to GDB a register set in 64-bit layout.
A patch (http://sourceware.org/ml/gdb-patches/2012-11/msg00228.html) a
while ago made GDB track a target_gdbarch per inferior, and as
consequence, fetch a target description per-inferior. This patch is
the GDBserver counterpart, that makes GDBserver keep track of each
process'es XML target description and register layout. So in the
example above, GDBserver will send the correct register set in 32-bit
layout to GDB.
A new "struct target_desc" object (tdesc for short) is added, that
holds the target description and register layout information about
each process. Each `struct process_info' holds a pointer to a target
description. The regcache also gains a pointer to a target
description, mainly for convenience, and parallel with GDB (and
possible future support for programs that flip processor modes).
The low target's arch_setup routines are responsible for setting the
process'es correct tdesc. This isn't that much different to how
things were done before, except that instead of detecting the inferior
process'es architecture and calling the corresponding
init_registers_FOO routine, which would change the regcache layout
globals and recreate the threads' regcaches, the regcache.c globals
are gone, and the init_registers_$BAR routines now each initialize a
separate global struct target_desc object (one for each arch variant
GDBserver supports), and so all the init_registers_$BAR routines that
are built into GDBserver are called early at GDBserver startup time
(similarly to how GDB handles its built-in target descriptions), and
then the arch_setup routine is responsible for making
process_info->tdesc point to one of these target description globals.
The regcache module is all parameterized to get the regcache's layout
from the tdesc object instead of the old register_bytes, etc. globals.
The threads' regcaches are now created lazily. The old scheme where
we created each of them when we added a new thread doesn't work
anymore, because we add the main thread/lwp before we see it stop for
the first time, and it is only when we see the thread stop for the
first time that we have a chance of determining the inferior's
architecture (through the_low_target.arch_setup). Therefore when we
add the main thread we don't know which architecture/tdesc its
regcache should have.
This patch makes the gdb.multi/multi-arch.exp test now pass against
(extended-remote) GDBserver. It currently fails, without this patch.
The IPA also uses the regcache, so it gains a new global struct
target_desc pointer, which points at the description of the process it
is loaded in.
Re. the linux-low.c & friends changes. Since the register map
etc. may differ between processes (64-bit vs 32-bit) etc., the
linux_target_ops num_regs, regmap and regset_bitmap data fields are no
longer sufficient. A new method is added in their place that returns
a pointer to a new struct that includes all info linux-low.c needs to
access registers of the current inferior.
The patch/discussion that originally introduced
linux-low.c:disabled_regsets mentions that the disabled_regsets set
may be different per mode (in a biarch setup), and indeed that is
cleared whenever we start a new (first) inferior, so that global is
moved as well behind the new `struct regs_info'.
On the x86 side:
I simply replaced the i387-fp.c:num_xmm_registers global with a check
for 64-bit or 32-bit process, which is equivalent to how the global
was set. This avoided coming up with some more general mechanism that
would work for all targets that use this module (GNU/Linux, Windows,
etc.).

* regformats/regdat.sh: Output #include tdesc.h. Make globals
static. Output a global target description pointer.
(init_registers_${name}): Adjust to initialize a
target description structure.
The GDBserver Aarch64 port includes the aarch64-without-fpu
description in the build, but doesn't actually use it anywhere. As
Linux always requires an FPU, just remove the dead code.
gdb/gdbserver/
2013-05-28 Pedro Alves <palves@redhat.com>
* Makefile.in (clean): Remove reference to aarch64-without-fpu.c.
(aarch64-without-fpu.c): Delete rule.
* configure.srv (aarch64*-*-linux*): Remove references to
aarch64-without-fpu.o and aarch64-without-fpu.xml.
* linux-aarch64-low.c (init_registers_aarch64_without_fpu): Remove
declaration.
The previous patches are still not sufficient to build gdbserver with
our copy of thread_db.h.
../../../src/gdb/gdbserver/thread-db.c: In function ‘find_one_thread’:
../../../src/gdb/gdbserver/thread-db.c:316:6: error: ‘struct lwp_info’ has no member named ‘th’
../../../src/gdb/gdbserver/thread-db.c: In function ‘attach_thread’:
../../../src/gdb/gdbserver/thread-db.c:341:6: error: ‘struct lwp_info’ has no member named ‘th’
../../../src/gdb/gdbserver/thread-db.c: In function ‘thread_db_get_tls_address’:
../../../src/gdb/gdbserver/thread-db.c:514:47: error: ‘struct lwp_info’ has no member named ‘th’
make: *** [thread-db.o] Error 1
First, linux-low.h is including <thread_db.h> directly instead of our
gdb_thread_db.h, although thread-db.c includes the latter. Then the
'th' field of struct lwp_info is only defined if HAVE_THREAD_DB_H is
defined, which is not true if we're using our replacement copy of
thread_db.h. We have a USE_THREAD_DB symbol defined if we're building
thread-db.c that's ideal for this, however, it's currently only
defined when compiling linux-low.c (through a Makefile rule). The
patch makes it defined when compiling any file.
