a2658febe2 add s390_gcc_target_options 
This adds s390_gcc_target_options, an implementation of the new
"gcc_target_options" gdbarch method.  This was needed because the
default implementation of the method doesn't work properly for S390,
as this architecture needs "-m31" rather than "-m32".

	* s390-linux-tdep.c (s390_gcc_target_options): New function.
	(s390_gdbarch_init): Add it to gdbarch.

458c8db89f Partial fix for PR breakpoints/10737: Make syscall info be per-arch instead of global 
This patch intends to partially fix PR breakpoints/10737, which is
about making the syscall information (for the "catch syscall" command)
be per-arch, instead of global.  This is not a full fix because of the
other issues pointed by Pedro here:

  <https://sourceware.org/bugzilla/show_bug.cgi?id=10737#c5>

However, I consider it a good step towards the real fix.  It will also
help me fix <https://sourceware.org/bugzilla/show_bug.cgi?id=17402>.

What this patch does, basically, is move the "syscalls_info"
struct to gdbarch.  Currently, the syscall information is stored in a
global variable inside gdb/xml-syscall.c, which means that there is no
easy way to correlate this info with the current target or
architecture being used, for example.  This causes strange behaviors,
because the syscall info is not re-read when the arch changes.  For
example, if you put a syscall catchpoint in syscall 5 on i386 (syscall
open), and then load a x86_64 program on GDB and put the same syscall
5 there (fstat on x86_64), you will still see that GDB tells you that
it is catching "open", even though it is not.  With this patch, GDB
correctly says that it will be catching fstat syscalls.

  (gdb) set architecture i386
  The target architecture is assumed to be i386
  (gdb) catch syscall 5
  Catchpoint 1 (syscall 'open' [5])
  (gdb) set architecture i386:x86-64
  The target architecture is assumed to be i386:x86-64
  (gdb) catch syscall 5
  Catchpoint 2 (syscall 'open' [5])

But with the patch:

  (gdb) set architecture i386
  The target architecture is assumed to be i386
  (gdb) catch syscall 5
  Catchpoint 1 (syscall 'open' [5])
  (gdb) set architecture i386:x86-64
  The target architecture is assumed to be i386:x86-64
  (gdb) catch syscall 5
  Catchpoint 2 (syscall 'fstat' [5])

As I said, there are still some problems on the "catch syscall"
mechanism, because (for example) the user should be able to "catch
syscall open" on i386, and then expect "open" to be caught also on
x86_64.  Currently, it doesn't work.  I intend to work on this later.

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)

5aa82d050d Replace 'core_regset_sections' by iterator method 
The core_regset_sections list in gdbarch (needed for multi-arch

99b7da5d7a S390: Migrate to regcache_supply/collect_regset. 
Rather than supplying own supply/collect functions, use the generic
functions regcache_supply_regset and regcache_collect_regset instead.
The register maps are rewritten accordingly and become much shorter
(and better readable) than before.

7fefa8d7d6 Rename 'descr' field in regset structure to 'regmap'. 
The regset structure's 'descr' field is intended to represent some
kind of "register map".  Thus, before making more use of it, this
change renames it to 'regmap' and adjusts the comment appropriately.

2ed3c037cf Use address_from_register in dwarf2-frame.c:read_addr_from_reg 
This patch fixes a problem that prevented use of the Dwarf unwinders on SPU,
because dwarf2-frame.c common code did not support the situation where the
stack and/or frame pointer is maintained in a *vector* register.  This is
because read_addr_from_reg is hard-coded to assume that such pointers can
be read from registers via a simple get_frame_register / unpack_pointer
operation.

Now, there *is* a routine address_from_register that calls into the
appropriate tdep routines to handle pointer values in "weird" registers
like on SPU, but it turns out I cannot simply change dwarf2-frame.c to
use address_from_register.  This is because address_from_register uses
value_from_register to create a (temporary) value, and that routine
at some point calls get_frame_id in order to set up that value's
VALUE_FRAME_ID entry.

However, the dwarf2-frame.c read_addr_from_reg routine will be called
during early unwinding (to unwind the frame's CFA), at which point the
frame's ID is not actually known yet!  This would cause an assert.

On the other hand, we may notice that VALUE_FRAME_ID is only needed in the
value returned by value_from_register if that value is later used as an
lvalue.  But this is obviously never done to the temporary value used in
address_from_register.  So, if we could change address_from_register to
not call value_from_register but instead accept constructing a value
that doesn't have VALUE_FRAME_ID set, things should be fine.

To do that, we can change the value_from_register callback to accept
a FRAME_ID instead of a FRAME; the only existing uses of the FRAME
argument were either to extract its frame ID, or its gdbarch.  (To
keep a way of getting at the latter, we also change the callback's
type from "f" to "m".)  Together with the required follow-on changes
in the existing value_from_register implementations (including the
default one), this seems to fix the problem.

As another minor interface cleanup, I've removed the explicit TYPE
argument from address_from_register.  This routine really always
uses a default pointer type, and in the new implementation it -to
some extent- relies on that fact, in that it will now no longer
handle types that require gdbarch_convert_register_p handling.

62261490a3 Fix gdb.trace/mi-traceframe-changed.exp on s390. 
The test fails on s390 with:

  -trace-find frame-number 0^M
  &"PC not available\n"^M
  ^done,found="1",tracepoint="1",traceframe="0",frame={level="-1",addr="<unavailable>",func="??",args=[]}^M
  (gdb) ^M
  FAIL: gdb.trace/mi-traceframe-changed.exp: tfile: -trace-find frame-number 0

tfile knows to infer the PC from the tracepoint's address if the PC
wasn't collected (tfile_fetch_registers) but, that only works on
targets whose PC register is a raw register, and on s390, the PC
register is a pseudo register.

But even if GDB doesn't know how to infer the value of PC, saying the
current frame is level -1 is a bug:

  ^done,found="1",tracepoint="1",traceframe="0",frame={level="-1",addr="<unavailable>",func="??",args=[]}^M
                                                       ^^^^^^^^^

'-1' is the level of the sentinel frame, which should never be visible.

This is caused by the s390's heuristic unwinder accepting the frame
(the fallback heuristic unwinders _always_ accept the frame), but then
the unwind->this_id method throws that "PC not available\n" error.

IOW, the s390's heuristic unwinder was never adjusted to handle
unavailable register values gracefully, which can happen with e.g., a
trimmed core file too.

This is just the minimal necessary for
<unavailable> frames, which at least gets us:

  (gdb) tfind
  Found trace frame 0, tracepoint 1
  #0  <unavailable> in ?? ()

That is, frame #0 instead of -1.

We could get better info out of "info frame" (this patch makes us show
"outermost"), but this change would still be necessary.

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.

0e5fae36f1 S/390: Rename source files to *-linux-* 
As suggested before, rename the S/390-related source files (tdep and nat)
such that "-linux-" occurs in the file name, like with other GNU/Linux
targets.  Since no other operating system is currently supported by GDB
on this architecture, this isn't strictly necessary.  But the old names
sometimes caused GDB contributors to miss these files when performing a
change that affects all GNU/Linux targets.  The latest such incident was
observed here:
