8f0435f75e Add 'regset' parameter to 'iterate_over_regset_sections_cb'
This adds the 'regset' parameter to the iterator callback.
Consequently the 'regset_from_core_section' method is dropped for all
targets that provide the iterator method.

This change prepares for replacing regset_from_core_section
everywhere, thereby eliminating one gdbarch interface.  Since the
iterator is usually no more complex than regset_from_core_section
alone, targets that previously didn't define core_regset_sections will
then gain multi-arch capable core file generation support without
increased complexity.

gdb/ChangeLog:

	* gdbarch.sh (iterate_over_regset_sections_cb): Add regset
	parameter.
	* gdbarch.h: Regenerate.
	* corelow.c (sniff_core_bfd): Don't sniff if gdbarch has a regset
	iterator.
	(get_core_register_section): Add parameter 'regset' and use it, if
	set.  Add parameter 'min_size' and verify the bfd section size
	against it.
	(get_core_registers_cb): Add parameter 'regset' and pass it to
	get_core_register section.  For the "standard" register sections
	".reg" and ".reg2", set an appropriate default for human_name.
	(get_core_registers): Don't abort when the gdbarch has an iterator
	but no regset_from_core_section.  Add NULL/0 for parameters
	'regset'/'min_size' in calls to get_core_register_section.
	* linux-tdep.c (linux_collect_regset_section_cb): Add parameter
	'regset' and use it instead of calling the
	regset_from_core_section gdbarch method.
	* i386-tdep.h (struct gdbarch_tdep): Add field 'fpregset'.
	* i386-tdep.c (i386_supply_xstateregset)
	(i386_collect_xstateregset, i386_xstateregset): Moved to
	i386-linux-tdep.c.
	(i386_regset_from_core_section): Drop handling for .reg-xfp and
	.reg-xstate.
	(i386_gdbarch_init): Set tdep field 'fpregset'.  Enable generic
	core file support only if the regset iterator hasn't been set.
	* i386-linux-tdep.c (i386_linux_supply_xstateregset)
	(i386_linux_collect_xstateregset, i386_linux_xstateregset): New.
	Moved from i386-tdep.c and renamed to *_linux*.
	(i386_linux_iterate_over_regset_sections): Add regset parameter to
	each callback invocation.  Allow any .reg-xstate size when reading
	from a core file.
	* amd64-tdep.c (amd64_supply_xstateregset)
	(amd64_collect_xstateregset, amd64_xstateregset): Moved to
	amd64-linux-tdep.c.
	(amd64_regset_from_core_section): Remove.
	(amd64_init_abi): Set new tdep field 'fpregset'.  No longer
	install an amd64-specific regset_from_core_section gdbarch method.
	* amd64-linux-tdep.c (amd64_linux_supply_xstateregset)
	(amd64_linux_collect_xstateregset, amd64_linux_xstateregset): New.
	Moved from amd64-tdep.c and renamed to *_linux*.
	(amd64_linux_iterate_over_regset_sections): Add regset parameter
	to each callback invocation.  Allow any .reg-xstate size when
	reading from a core file.
	* arm-linux-tdep.c (arm_linux_regset_from_core_section): Remove.
	(arm_linux_iterate_over_regset_sections): Add regset parameter to
	each callback invocation.
	(arm_linux_init_abi): No longer set the regset_from_core_section
	gdbarch method.
	* ppc-linux-tdep.c (ppc_linux_regset_from_core_section): Remove.
	(ppc_linux_iterate_over_regset_sections): Add regset parameter to
	each callback invocation.
	(ppc_linux_init_abi): No longer set the regset_from_core_section
	gdbarch method.
	* s390-linux-tdep.c (struct gdbarch_tdep): Remove the fields
	gregset, sizeof_gregset, fpregset, and sizeof_fpregset.
	(s390_regset_from_core_section): Remove.
	(s390_iterate_over_regset_sections): Add regset parameter to each
	callback invocation.
	(s390_gdbarch_init): No longer set the regset_from_core_section
	gdbarch method.  Drop initialization of deleted tdep fields.

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.

45741a9c32 Add new infrun.h header.
Move infrun.c declarations out of inferior.h to a new infrun.h file.

Tested by building on:

 i686-w64-mingw32, enable-targets=all
 x86_64-linux, enable-targets=all
 i586-pc-msdosdjgpp

And also grepped the whole tree for each symbol moved to find where

ecc37a5acc X86: Replace regset_alloc() invocations by static regset structures.
After removal of the regset_alloc invocations, the appropriate tdep
fields become obsolete and are thus removed.

09424cff8c Remove 'arch' field from regset structure.
Removes the 'arch' field from the regset structure, since it
represents the only "dynamic" data in a regset.  It was referenced in
some regset supply- and collect routines, to get access to the gdbarch
associated with the regset.  Naturally, the affected routines always
have access to the regcache to be supplied to or collected from.  Thus
the gdbarch associated with that regcache can be used instead.

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.

410a0ff2df Remove `expout*' globals from parser-defs.h
This commit removes the "expout*" globals from our parser code, turning
them into a structure that is passed when an expression needs to be
evaluated.  This is the initial step to make our parser less
"globalized".

This is mostly a mechanical patch, which creates a structure containing
the "expout*" globals and then modify all the functions that handle them
in order to take the structure as argument.  It is big, and has been
reviewed at least 4 times, so I think everything is covered.

efd66ac669 change minsym representation
In a later patch we're going to change the minimal symbol address
calculation to apply section offsets at the point of use.  To make it
simpler to catch potential problem spots, this patch changes the
representation of minimal symbols and introduces new
minimal-symbol-specific variants of the various accessors.  This is
necessary because it would be excessively ambitious to try to convert
all the symbol types at once.

The core of this change is just renaming a field in minimal_symbol;
the rest is just a fairly mechanical rewording.

d7b30f6729 Fix for PR tdep/16397: SystemTap SDT probe support for x86 doesn't work with "triplet operands"
This is the continuation of what Joel proposed on:

<https://sourceware.org/ml/gdb-patches/2013-12/msg00977.html>

Now that I have already submitted and pushed the patch to split
i386_stap_parse_special_token into two smaller functions, it is indeed
simpler to understand this patch.

It occurs because, on x86, triplet displacement operands are allowed
(like "-4+8-20(%rbp)"), and the current parser for this expression is
buggy.  It does not correctly extract the register name from the
expression, which leads to incorrect evaluation.  The parser was also
being very "generous" with the expression, so I included a few more
checks to ensure that we're indeed dealing with a triplet displacement
operand.

This patch also includes testcases for the two different kind of
expressions that can be encountered on x86: the triplet displacement
(explained above) and the three-argument displacement (as in
"(%rbx,%ebx,-8)").  The tests are obviously arch-dependent and are
placed under gdb.arch/.

5acfdbae5d Split i386_stap_parse_special_token into smaller functions
This patch reorganizes code on gdb/i386-tdep.c's SystemTap SDT probe
support functions.  Before it, the code to parse special operands on x86
lived in a single, big function.  This patch creates 2 new functions
that makes the code more organized and removes a few indentation levels
(which is always good IMO).

I haven't modified anything logical in the functions, i.e., there's still
one latent bug on i386_stap_parse_special_token_triplet now.  I will soon
post a patch to fix this, and to also improve the readability of the two
new functions.

05c0465e16 Extend SystemTap SDT probe argument parser
This patch extends the current generic parser for SystemTap SDT probe
arguments.  It can be almost considered a cleanup, but the main point of
it is actually to allow the generic parser to accept multiple prefixes
and suffixes for the its operands (i.e., integers, register names, and
register indirection).

I have chosen to implement this as a list of const strings, and declare
this list as "static" inside each target's method used to initialize
gdbarch.

This patch is actually a preparation for an upcoming patch for ARM,
which implements the support for multiple integer prefixes (as defined
by ARM's asm spec).  And AArch64 will also need this, for the same
reason.

This patch was regtested on all architectures that it touches (i.e.,
i386, x86_64, ARM, PPC/PPC64, s390x and IA-64).  No regressions were found.

5ce0145de7 "tfind" across unavailable-stack frames.
Like when stepping, the current stack frame location is expected to be
printed as result of tfind command, if that results in moving to a
different function.  In tfind_1 we see:

  if (from_tty
      && (has_stack_frames () || traceframe_number >= 0))
    {
      enum print_what print_what;

      /* NOTE: in imitation of the step command, try to determine
         whether we have made a transition from one function to
         another.  If so, we'll print the "stack frame" (ie. the new
         function and it's arguments) -- otherwise we'll just show the
         new source line.  */

      if (frame_id_eq (old_frame_id,
                       get_frame_id (get_current_frame ())))
        print_what = SRC_LINE;
      else
        print_what = SRC_AND_LOC;

      print_stack_frame (get_selected_frame (NULL), 1, print_what, 1);
      do_displays ();
    }

However, when we haven't collected any registers in the tracepoint
(collect $regs), that doesn't actually work:

 (gdb) tstart
 (gdb) info tracepoints
 Num     Type           Disp Enb Address    What
 1       tracepoint     keep y   0x080483b7 in func0
                                            at ../.././../git/gdb/testsuite/gdb.trace/circ.c:28
         collect testload
     installed on target

                                            at ../.././../git/gdb/testsuite/gdb.trace/circ.c:32
         collect testload
     installed on target
 (gdb) c
 Continuing.

 Breakpoint 3, end () at ../.././../git/gdb/testsuite/gdb.trace/circ.c:72
 72    }
 (gdb) tstop
 (gdb) tfind start
 Found trace frame 0, tracepoint 1
 #0  func0 () at ../.././../git/gdb/testsuite/gdb.trace/circ.c:28
 28    }
 (gdb) tfind
 Found trace frame 1, tracepoint 2
 32    }
 (gdb)

When we don't have info about the stack available
(UNWIND_UNAVAILABLE), frames end up with outer_frame_id as frame ID.
And in the scenario above, the issue is that both frames before and
after the second tfind (the frames for func0 an func1) have the same
id (outer_frame_id), so the frame_id_eq check returns false, even
though the frames were of different functions.  GDB knows that,
because the PC is inferred from the tracepoint's address, even if no
registers were collected.

To fix this, this patch adds support for frame ids with a valid code
address, but <unavailable> stack address, and then makes the unwinders
use that instead of the catch-all outer_frame_id for such frames.  The
frame_id_eq check in tfind_1 then automatically does the right thing
as expected.

I tested with --directory=gdb.trace/ , before/after the patch, and
compared the resulting gdb.logs, then adjusted the tests to expect the
extra output that came out.  Turns out that was only circ.exp, the
original test that actually brought this issue to light.

Tested on x86_64 Fedora 17, native and gdbserver.

0865b04a4d Use target_read_code in skip_prologue (i386)
GDB is able to cache memory accesses requested in target_read_code,
so target_read_code is more efficient than general target_read_memory.

This patch uses target_read_code and its variants to read target
memory in the functions related to i386_skip_prologue.  It improves
the performance when doing 'b foo' (foo is a function) in remote
debugging.

Nowadays, when we set a breakpoint on function f1, GDB will fetch the
code in f1 to determine the start of the function body (say skip the
prologue), it requests read from target many times.  With this patch
applied, the number of RSP 'm' packets are reduced.

a0bcdaa75e More invalid pointer to pointer conversions.
As a follow up to:

  http://sourceware.org/ml/gdb-patches/2013-03/msg00449.html

In a nutshell, casts between 'char **' <-> 'unsigned char **' and
'char **' <-> 'const char **' are invalid.

I grepped for "\*\*) &" and found these.  There's another one in
demangle.c, but I've split fixing that one to a separate patch.

I think the ada_decode_symbol change is perhaps the one that could be
surprising.  The function's description has this comment, which makes
things much clearer:

   The GSYMBOL parameter is "mutable" in the C++ sense: logically
   const, but nevertheless modified to a semantically equivalent form
   when a decoded name is cached in it.  */

 const char *
 ada_decode_symbol (const struct general_symbol_info *gsymbol)

With that out of the way, I think the patch ends up being pretty
obvious.

Tested on x86_64 Fedora 17.

	* arm-linux-tdep.c (arm_stap_parse_special_token): Add 'char *'

	invalid casts to from 'const char **' to 'char **'.
	(_initialize_demangle): Remove cast.
	* i386-tdep.c (i386_stap_parse_special_token): : Add 'char *'
