8689682cc3 Implement breakpoint_kind_from_pc and sw_breakpoint_from_kind for ARM in GDBServer.
ARM can have multiple breakpoint types based on the instruction set
it's currently in: arm, thumb or thumb2.

GDBServer needs to know what breakpoint is to be inserted at location
when inserting a breakpoint.

This is handled by the breakpoint_kind_from_pc and sw_breakpoint_from_kind
target ops introduced in a previous patch, this patch adds the
arm_breakpoint_kind_from_pc and arm_sw_breakpoint_from_kind implementation so
that the proper breakpoint type is returned based on the pc.

Also in order to share some code with GDB a new file called arm.c have been
introduced in arch/.

While this file does not contain much yet future patches will add more
to it thus the inclusion at this stage.

No regressions on Ubuntu 14.04 on ARMv7 and x86.
With gdbserver-{native,extended} / { -marm -mthumb }

bb903df05b Add support for fast tracepoints
This patch adds support for fast tracepoints for aarch64-linux.  With this
implementation, a tracepoint can only be placed in a +/- 128MB range of
the jump pad.  This is due to the unconditional branch instruction
being limited to a (26 bit << 2) offset from the current PC.

Three target operations are implemented:

- target_install_fast_tracepoint_jump_pad

Building the jump pad the biggest change of this patch.  We need to add
functions to emit all instructions needed to save and restore the
current state when the tracepoint is hit.  As well as implementing a
lock and creating a collecting_t object identifying the current thread.

Steps performed by the jump pad:

  * Save the current state on the stack.
  * Push a collecting_t object on the stack.  We read the special
  tpidr_el0 system register to get the thread ID.
  * Spin-lock on the shared memory location of all tracing threads.  We
  write the address of our collecting_t object there once we have the
  lock.
  * Call gdb_collect.
  * Release the lock.
  * Restore the state.

  * Execute the replaced instruction which will have been relocated.
  * Jump back to the program.

- target_get_thread_area

As implemented in ps_get_thread_area, target_get_thread_area uses ptrace
to fetch the NT_ARM_TLS register.  At the architecture level, NT_ARM_TLS
represents the tpidr_el0 system register.

So this ptrace call (if lwpid is the current thread):
~~~
ptrace (PTRACE_GETREGSET, lwpid, NT_ARM_TLS, &iovec);
~~~

Is equivalent to the following instruction:
~~~
msr x0, tpidr_el0
~~~

This instruction is used when creating the collecting_t object that
GDBserver can read to know if a given thread is currently tracing.

So target_get_thread_area must get the same thread IDs as what the jump
pad writes into its collecting_t object.

- target_get_min_fast_tracepoint_insn_len

This just returns 4.

787749ead6 Move instruction decoding into new arch/ directory
This patch moves the following functions into the arch/ common
directory, in new files arch/aarch64-insn.{h,c}.  They are prefixed with
'aarch64_':

 - aarch64_decode_adrp
 - aarch64_decode_b
 - aarch64_decode_cb
 - aarch64_decode_tb

We will need them to implement fast tracepoints in GDBserver.

For consistency, this patch also adds the 'aarch64_' prefix to static
decoding functions that do not need to be shared right now.

V2:
 make sure the formatting issues propagated
 fix `gdbserver/configure.srv'.

554717a3ed Move common aarch64 HW breakpoint/watchpoint code to nat/
When I look at test fails related to watchpoint on aarch64-linux,
I find there are some code duplicates between GDB and GDBserver.
This patch is to move some of them to a nat/aarch64-linux-hw-point.{h,c}.

The only change I do is about the dr_changed_t typedef, which was
ULONGEST in GDB and 'unsigned long long' in GDBserver.  Each bit
of dr_changed_t represents a status of each HW breakpoint or
watchpoint register, and the max number of HW breakpoint or watchpoint
registers is 16, so the width of 'unsigned long long' is sufficient.

8cc73a3902 Move code to disable ASR to nat/
This patch moves the shared code present on
gdb/linux-nat.c:linux_nat_create_inferior and
gdb/gdbserver/linux-low.c:linux_create_inferior to
nat/linux-personality.c.  This code is responsible for disabling
address space randomization based on user setting, and using
<sys/personality.h> to do that.  I decided to put the prototype of the
maybe_disable_address_space_randomization on nat/linux-osdata.h
because it seemed the best place to put it.

I regression-tested this patch on Fedora 20 x86_64, and found no
regressions.

cdf436294f Detect 64-bit-ness in PowerPC Book III-E
This patch is to teach both GDB and GDBServer to detect 64-bit inferior
correctly.  We find a problem that GDBServer is unable to detect on a
e5500 core processor.  Current GDBServer assumes that MSR is a 64-bit
register, but MSR is a 32-bit register in Book III-E.  This patch is
to fix this problem by checking the right bit in MSR, in order to handle
both Book III-S and Book III-E.  In order to detect Book III-S and
Book III-E, we check the PPC_FEATURE_BOOKE from the host's HWCAP (by
getauxval on glibc >= 2.16.  If getauxval doesn't exist, we implement
the fallback by parsing /proc/self/auxv), because it should an invariant
on the same machine cross different processes.

In order to share code, I add nat/ppc-linux.c for both GDB and
GDBserver side.

df7e526582 Rename 32- and 64-bit Intel files from "i386" to "x86"
This commit renames nine files that contain code used by both 32- and
64-bit Intel ports such that their names are prefixed with "x86"
rather than "i386".  All types, functions and variables within these
files are likewise renamed such that their names are prefixed with
"x86" rather than "i386".  This makes GDB follow the convention used
by gdbserver such that 32-bit Intel code lives in files called
"i386-*", 64-bit Intel code lives in files called "amd64-*", and code
for both 32- and 64-bit Intel lives in files called "x86-*".

This commit only renames OS-independent files.  The Linux ports of
both GDB and gdbserver now follow the i386/amd64/x86 convention fully.
Some ports still use the old convention where "i386" in file/function/
type/variable names can mean "32-bit only" or "32- and 64-bit" but I
don't want to touch ports I can't fully test except where absolutely
necessary.

01f9f808e2 Add AVX512 registers support to GDB and GDBserver.
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.

For more information please see

379a5e2d36 nameless LOAD_DLL_DEBUG_EVENT causes ntdll.dll to be missing
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).

	* configure.srv: Add safe-ctype.o and lbasename.o to srv_tgtobj

e6352c8f63 Make x86-lynx GDBserver pass XML register map to GDB.
This is not strictly needed, since both GDB and GDBserver seem
to agree on the register numbering without this.  But this allows
us to make sure that this is always going to be the case.

50681a2705 Allow powerpc-*-lynxos* GDBserver to send register map via XML...
... back to GDB.  The transfer occurs when GDB sends the
'qXfer:features:read:target.xml' packet.  This allows us to make
sure that GDB and GDBserver use the same register numbering.
This is important on Lynx 178, where GDB selects the rs6000:6000
architecture by default instead of the powerpc:common architecture.
