96235dc1ac S390: Add guarded-storage register definitions and tdescs
Newer Linux kernel versions offer two new register sets in support of the
z/Architecture's guarded storage facility.  This patch adds XML
descriptions and the respective autogenerated .c and .dat files for
s390/s390x targets with this feature.

f49ff00066 [GDBserver] Centralize tdesc for i386-linux
tdesc_i386_XXX_linux is used in many places in linux-x86-low.c and this
patch adds a new function i386_linux_read_description to return the right
tdesc according to xcr0.  i386_linux_read_description is quite similar to
the counterpart in GDB, and the following patch will share the duplicated
code, so this patch adds arch/tdesc.h includes the declarations of various
tdesc apis which are used by the shared code.  The generated c feature
files can include arch/tdesc.h only.

f7000548a2 Use VEC for target_desc.reg_defs
Nowadays, target_desc.reg_defs is a pointer points to a pre-generated
array, which is not flexible.  This patch changes it from an array
to a VEC so that GDBserver can create target descriptions dynamically
later.  Instead of using pre-generated array, the -generated.c calls
VEC_safe_push to add each register to vector.

Since target_desc.reg_defs is used in IPA, we need to build common/vec.c
for IPA too.

c9a5e2a5b2 Adjust code generated by regformats/regdat.sh
regformats/regdat.sh generate some *-generated.c files when GDBserver
is built.  Each .c file has some static variables, which are only used
within function init_registers_XXX, like this,

static struct reg regs_i386_linux[] = {
  { "eax", 0, 32 },
  { "ecx", 32, 32 },
  ...
};

static const char *expedite_regs_i386_linux[] = { "ebp", "esp", "eip", 0 };
static const char *xmltarget_i386_linux = "i386-linux.xml";

void
init_registers_i386_linux (void)
{
  ...
}

This patch moves these static variables' definitions to function
init_registers_XXX, so the generated files look like this,

void
init_registers_i386_linux (void)
{
  static struct target_desc tdesc_i386_linux_s;
  struct target_desc *result = &tdesc_i386_linux_s;
static struct reg regs_i386_linux[] = {
  ...
};

static const char *expedite_regs_i386_linux[] = { "ebp", "esp", "eip", 0 };
static const char *xmltarget_i386_linux = "i386-linux.xml";

  ...
}

We want GDBserver create target descriptions dynamically in each
init_registers_XXXX functions, so this patch moves all the related code
into function init_registers_XXXX, so that the following patch can easily
change function init_registers_XXXX to create target description
dynamically, rather than using current pre-generated array.

adc764e7d2 Use target_desc fields expedite_regs and xmltarget ifndef IN_PROCESS_AGENT
struct target_desc is used by both GDBserver and IPA, but fields
expedite_regs and xmltarget are only used in GDBserver, so this patch wraps

51547df62c Add support for Intel PKRU register to GDB and GDBserver.
This patch adds support for the registers added by the
Memory Protection Keys for Userspace (PKU aka PKEYs) feature.
Native and remote debugging are covered by this patch.

The XSAVE area is extended with a new state containing
the 32-bit wide PKRU register. The new register is added to
amd64-avx-mpx_avx512-* tdesc, thus it is renamed accordingly. Also,
respective xstate mask X86_XSTATE_AVX_MPX_AVX512_MASK is renamed to
X86_XSTATE_AVX_MPX_AVX512_PKU_MASK to reflect the new feature set
it supports.

a1fa17ee15 Add target description for avx-avx512.
Add a dedicated target description for the feature combination
avx-avx512 as implemented by certain IA CPU models.

The corresponding X86_XSTATE_AVX_AVX512_MASK already exists, but shared
the tdesc with X86_XSTATE_AVX_MPX_AVX512_MASK. This caused MPX registers
displayed as undefined on CPUs that only implemented
X86_XSTATE_AVX_AVX512_MASK, which is undesired. This patch solves this issue.

This patch also corrects the wrong usage of x32-avx-mpx-avx512, which is
replaced by x32-avx-avx512. The MPX feature is not implemented in x32 mode.

22049425ce Rename target descriptions to reflect actual content of description.
To better reflect the actual feature set covered by the IA target
descriptions, the existing descriptions are renamed. Each feature of
the extended state is added to the name of a description or xstate mask
starting from AVX.
For example, amd64-mpx-avx512-linux becomes amd64-avx-mpx-avx512-linux,
while amd64-avx-linux remains unchanged.
Likewise, the corresponding xstate masks are changed, e.g. from
X86_XSTATE_MPX_AVX512_MASK to X86_XSTATE_AVX_MPX_AVX512_MASK.

f42bf748e4 Re-factor (i386|amd64)mpx target descriptions.
In the previous patch a new set of target descriptions
(i386|amd64)-avx-mpx were added  being same as the (i386|amd64)-mpx.
This patch removes AVX feature from  (i386|amd64)-mpx target
description set.

This way the (i386|amd64)avx_mpx(_linux|) set has AVX and MPX features
and (i386|amd64)mpx(_linux|) only MPX.

2b863f512d Add target descriptions for AVX + MPX
The current MPX target descriptions assume that MPX is always combined
with AVX, however that's not correct.  We can have machines with MPX
and without AVX; or machines with AVX and without MPX.

This patch adds new target descriptions for machines that support
both MPX and AVX, as duplicates of the existing MPX descriptions.

The following commit will remove AVX from the MPX-only descriptions.

164224e96c Fix for remote G Packet message too long error for baremetal.
Prior to version MicroBlaze v8.10.a,EDK 13.1, XMD's gdbserver stub returned 57
registers in response to GDB's G request. Starting with version MicroBlaze
v8.10.a, EDK 13.1, XMD added the slr and shr register, for a count of 59
registers. This patch adds these registers to the expected G response. This patch
fixes the above problem for baremetal and also supports the backward compatibility.

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.

bdf61915fc Have regdat.sh always rewrite the output register file
The rules for generating the output register files look like:

amd64.c : $(srcdir)/../regformats/i386/amd64.dat $(regdat_sh)
	$(SHELL) $(regdat_sh) $(srcdir)/../regformats/i386/amd64.dat amd64.c

According to this rule, if regdat.sh is newer than amd64.c, then
regdat.sh shall be invoked on amd64.dat.  According to regdat.sh, if the
script determines that the output file amd64.c has not changed, then it
will not overwrite the existing output file.  This means that a
subsequent invocation of make will trigger the above rule again as
regdat.sh will be perpetually newer than amd64.c.

This then shows up in the make output like so:

/bin/bash ./../regformats/regdat.sh ./../regformats/i386/amd64-linux.dat amd64-linux.c
amd64-linux.c unchanged.
/bin/bash ./../regformats/regdat.sh ./../regformats/i386/amd64-avx-linux.dat amd64-avx-linux.c
amd64-avx-linux.c unchanged.
...

To fix this pathological behavior, it suffices to have regdat.sh
unconditionally rewrite the output register file.

On my machine, which has a regdat.sh file that is newer than some of the
input register files, this change speeds up every invocation of make
under gdb/ by about 5 seconds.

3aee891821 [GDBserver] Multi-process + multi-arch
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.).

Tested:

  GNU/Linux IA64
  GNU/Linux MIPS64
  GNU/Linux PowerPC (Fedora 16)
  GNU/Linux s390x (Fedora 16)
  GNU/Linux sparc64 (Debian)
  GNU/Linux x86_64, -m64 and -m32 (Fedora 17)

Cross built, and smoke tested:

6ac1c0821e [AArch64] Remove all traces of aarch64-without-fpu.xml.
The aarch64-without-fpu description is unused.

Linux requires an FPU, so the AArch64 native port always returns the
with-fpu variant:

static const struct target_desc *
aarch64_linux_read_description (struct target_ops *ops)
{
  initialize_tdesc_aarch64 ();
  return tdesc_aarch64;
}

When the target doesn't report a target description at all, we
fallback to a register set with an FPU:

aarch64_gdbarch_init ()
...
  if (!tdesc_has_registers (tdesc))
    tdesc = tdesc_aarch64;

This just removes the dead description.

Tested by building on x86_64 Fedora 17 with --enable=targets=all.

0b1afbb37b Consistent use of (C) after "Copyright".
While writing the previous patch, I noticed that we're not consistent
with the (C) in the copyright header.  The maintainers manual prefers
having it, though also says it's optional.  We have over 10x more
files with (C) than without in gdb's code, so I spent a few minutes
grepping and fixing.  Funny enough, the testsuite has it backwards.
I'll leave that for another time.
