gdb: Fix phony iconv build

Cross building gdb for mingw32 on Fedora 23 fails with:

  x86_64-w64-mingw32-g++ -g -O2  [...]  ../../src/gdb/charset.c
  In file included from ../../src/gdb/charset.c:21:0:

     iconv_t m_desc;

 size_t r = iconv (m_desc, &inptr, &m_bytes, &outptr, &out_avail);
   ^

This is a regression caused by commit cda6c55bd399 (Turn wchar
iterator into a class).  The problem is that iconv_t is now exposed in
gdb/charset.h, while before it was only used in gdb/charset.c.

gdb/charset.c, under #ifdef PHONY_ICONV, does:

 #undef iconv_t
 #define iconv_t int

So it seems the simplest is to use 'int' in the header file too.

indicate is the instruction uses a long immediate (LIMM).  In the case
of short instruction, this LIMM indicator depends on the ISA version
used. Thus, for ARCv1 processors, the LIMM indicator is 0x3E, the same
value used in "long" instructions.  However, for the ARCv2 processors,
this LIMM indicator is 0x1E.

Convert tid_range_parser and get_number_or_range to classes

This converts tid_range_parser and get_number_or_range to be classes.
The various tid_range_parser_* and get_number_or_range_* functions
become methods on the respective classes.  Then it updates the users
to follow.

The rationale for the change is that this provides better
encapsulation.  For example, this forced me to think of a better
interface between tid_range_parser and get_number_or_range, since the
former peeked into the latter's internals a bit too much.  That ended
up resulting mostly in these two not-just-straight-1-1 changes:

  void
 -tid_range_parser_skip (struct tid_range_parser *parser)
 +tid_range_parser::skip_range ()
  {
 ...

 -  tid_range_parser_init (parser, parser->range_parser.end_ptr,
 -  parser->default_inferior);
 +  m_range_parser.skip_range ();
 +  init (m_range_parser.string (), m_default_inferior);
  }

 and:

    /* If we successfully parsed a thread number or finished parsing a
       thread range, switch back to assuming the next TID is
       inferior-qualified.  */
 -  if (parser->range_parser.end_ptr == NULL
 -      || parser->range_parser.string == parser->range_parser.end_ptr)
 +  if (!m_range_parser.in_range ())
      {

For the same reason (encapsulation), this moves the enum
tid_range_state definition to within the tid_parser class's scope,
since that is private implementation detail.

While at it, switch to use "bool" for booleans.

Fixup gdb.python/py-value.exp for bare-metal aarch64-elf

I noticed that testing aarch64-elf gdb with a physical board
ran into issues with gdb.python/py-value.exp. Further investigation showed
that we were actually trying to dereference a NULL pointer (argv) when trying
to access argv[0].

Being bare-metal, argv is not guaranteed to be valid. So we need to make sure
argv is sane before accessing argv[0].

The following patch fixes up the test program to check for a NULL argv and also
improves the testcase a bit so it doesn't have to work with a hardcoded argc
value.

[AArch64] Track FP registers in prologue analyzer

We don't track FP registers in aarch64 prologue analyzer, so this causes
an internal error when FP registers are saved by "stp" instruction in
prologue (stp d8, d9, [sp,#128]),

 tbreak _Unwind_RaiseException^M
 aarch64-tdep.c:335: internal-error: CORE_ADDR aarch64_analyze_prologue(gdbarch*, CORE_ADDR, CORE_ADDR, aarch64_prologue_cache*): Assertion `inst.operands[0].type == AARCH64_OPND_Rt' failed.^M
 A problem internal to GDB has been detected,

This patch teaches GDB to track FP registers (D registers) in prologue
analyzer.

Always descend into output section statements in lang_do_assignments

See https://sourceware.org/ml/binutils/2016-07/msg00091.html
This patch stop --gc-sections elf_gc_sweep_symbol localizing symbols
that ought to remain global.

The difficulty with always descending into output section statements
is that symbols defined by the script in such statements don't have
a bfd section when lang_do_assignments runs early in the link process.
There are two approaches to curing this problem.  Either we can
create the bfd section early, or we can use a special section.  This
patch takes the latter approach and uses bfd_und_section.  (Creating
bfd sections early results in changed output section order, and thus
lots of testsuite failures.  You can't create all output sections
early to ensure proper ordering as KEEP then stops empty sections
from being stripped.)

The wrinkle with this approach is that some code that runs at
gc-sections time needs to be made aware of the odd defined symbols
using bfd_und_section.

MIPS64: Adjust cfi* testcases.

The CFI* testcases fail on MIPS64 because the augmentation string does
not match the regexp. This is because MIPS64 doesn't use the default of
4 for DWARF2_FDE_RELOC_SIZE which ends up as "b" in the augmentation
string. MIPS64 uses the address size which is 8 resulting in "c".

Adding c to the regexp fixes a couple of them. Others also need
adjustments in the FDE header lines due to different
sizes/offsets.

Remove Java support

This patch removes the Java support from gdb.  gcj has not seen much
development or use for years now, and was recently removed from GCC.
This patch changes gdb to follow; in the unlikely event that there are
still users using gcj, they can continue to use an older gdb to debug.
Or, they can debug in C++ mode.

Built and regtested on x86-64 Fedora 24.

mips-tdep: Make FCRs always 32-bit

Fix a regression from commit f8b73d13b7ca ("Target-described register
support for MIPS"),
<https://sourceware.org/ml/gdb-patches/2007-05/msg00340.html>,
<https://sourceware.org/ml/gdb-patches/2007-06/msg00256.html>, which
caused Floating Point Control Registers (FCRs) to be shown as 64-bit
with 64-bit targets.

This came from the legacy register format where all raw registers
matched the width of the architecture regardless of their actual size.
The correct size was then set in `mips_register_type' for cooked
registers presented to the user, which in the case of FCRs meant the
cooked size was always forced to 32 bits, reflecting their actual
hardware size, even though the raw format carried them in 64-bit
quantities on 64-bit targets.  The upper 32 bits carried in the raw FCR
format have always been don't-cares, not actually retrieved from
hardware and never written back.

With the introduction of XML register descriptions the layout of
previously defined raw registers has been preserved, so as to keep
existing register handling code unchanged and make it easier for GDB and
`gdbserver' to interact with each other whether neither, either or both
parties talking over RSP support XML register descriptions.  For the
XML-described case however `mips_register_type' is not used in raw to
cooked register conversion, so any special cases coded there are not
taken into account.

Instead a new function, `mips_pseudo_register_type', has been introduced
to handle size conversion, however lacking the special case for FCRs for
the Linux and the now defunct IRIX target.  The correct size has been
maintained for embedded targets however, due to the bundling of FCRs
with the embedded registers under the `rawnum >= MIPS_EMBED_FP0_REGNUM +
32' condition.

Add the missing case to `mips_pseudo_register_type' then, referring to
the FCR indices explicitly, and observing that between
`MIPS_EMBED_FP0_REGNUM + 32' and `MIPS_FIRST_EMBED_REGNUM' there is an
unused register slot whose contents are ignored so with the removal of
embedded FCRs from under that condition we don't have to care about it
and we can refer to the embedded registers starting from
MIPS_FIRST_EMBED_REGNUM instead.

Add a test case too so that we have means to check automatically that
the correct user-visible size of FCRs is maintained.

Fix PR11094: JIT breakpoint is not properly recreated on reruns

Even though this was supposedly in the gdb 7.2 timeframe, the testcase
in PR11094 crashes current GDB with a segfault:

  Program received signal SIGSEGV, Segmentation fault.

  at src/gdb/breakpoint.c:7026
  [...]

This is GDB trying to print the location spec of the JIT event
breakpoint, but that's an internal breakpoint without one.

If I add a NULL check, then we see that the JIT breakpoint is now
pending (because its location has shlib_disabled set):

  (gdb) maint info breakpoints
  Num     Type           Disp Enb Address            What
  [...]
  -8      jit events     keep y   <PENDING>           inf 1
  [...]

But that's incorrect.  GDB should have managed to recreate the JIT
breakpoint's location for the second run.  So the problem is
elsewhere.

The problem is that if the JIT loads at the same address on the second
run, we never recreate the JIT breakpoint, because we hit this early
return:

  static int
  jit_breakpoint_re_set_internal (struct gdbarch *gdbarch,
  struct jit_program_space_data *ps_data)
  {
    [...]
    if (ps_data->cached_code_address == addr)
      return 0;

    [...]
      delete_breakpoint (ps_data->jit_breakpoint);
    [...]
    ps_data->jit_breakpoint = create_jit_event_breakpoint (gdbarch, addr);

Fix this by deleting the breakpoint and discarding the cached code
address when the objfile where the previous JIT breakpoint was found
is deleted/unloaded in the first place.

The test that was originally added for PR11094 doesn't trip on this
because:

  #1 - It doesn't test the case of the JIT descriptor's address _not_
       changing between reruns.

  #2 - And then it doesn't do "maint info breakpoints", or really
       anything with the JIT at all.

  #3 - and even then, to trigger the problem the JIT descriptor needs
       to be in a separate library, while the current test puts it in
       the main program.

The patch extends the test to cover all combinations of these
scenarios.

(top level): Add "standalone vs shared lib" and "change address"

Fix a few gdb.base/jit-simple.exp problems

I noticed that we sometimes get this:

  (gdb) print &__jit_debug_descriptor
  $1 = (struct jit_descriptor *) 0x601040 <__jit_debug_descriptor>
  (gdb) PASS: gdb.base/jit-simple.exp: blah 1
  [...]
  (gdb) run
  [...]
  Starting program: build/gdb/testsuite/outputs/gdb.base/jit-simple/jit-simple
  Unsupported JIT protocol version 4 in descriptor (expected 1)

  Breakpoint 2, main () at src/gdb/testsuite/gdb.base/jit-simple.c:36
  36        return 0;
  (gdb) print &__jit_debug_descriptor
  $2 = (struct jit_descriptor *) 0x601040 <__jit_debug_descriptor>
  (gdb) PASS: gdb.base/jit-simple.exp: blah 1

All tests PASSed, but note the "Unsupported JIT protocol version 4"
message.

Also notice that "__jit_debug_descriptor" has the same address before
and after the rerun, while the test is built in a way that should make
that address change between runs.

The test doesn't catch any of this because it doesn't compare
before/after addresses.

And then notice the "blah 1" test messages.  "blah" is clearly a WIP
message, but it should be at least "blah 2" the second time.  :-)

The reason this sometimes happens is that the test recompiles the
program and expects gdb to reload it automaticallyt on "run".  However,
if the original program and the new recompilation happen to be in the
same second, then gdb does not realize that the binary needs to be
reloaded.  (This is an old problem out of scope of this series.)  If
that happens, then GDB ends up using the wrong symbols for the program
that it spawns, reads the JIT descriptor out of the wrong address,
finds garbage, and prints that "unsupported version" notice.

Fix that in the same way gdb.base/reread.exp handles it -- by sleeping
one second before recompiling.

The .exp patch is an obvious typo fix I think.  The regex was written to
accept "ADDR in main" and I find it OK as checking .debug_line validity is not
the purpose of this testfile.

gcc-4.8.5-11.el7.x86_64 did not put the 'mov $0x0,%eax' instruction there at
all so there was no problem with .debug_line.

2016-10-05  Jan Kratochvil  <jan.kratochvil@redhat.com>

* gdb.arch/i386-signal.exp (backtrace 10): Fix #2 typo.

PR remote/20655 - small fix in handle_tracepoint_bkpts

handle_tracepoint_bkpts has two parallel "if"s.  This changes the
second one to check ipa_error_tracepoint, which seems to be what was
intended.

PR remote/20655:
* tracepoint.c (handle_tracepoint_bkpts): Check
ipa_error_tracepoint, not ipa_stopping_tracepoint.

PR gdb/20653 - small cleanup in string_to_explicit_location

This bug points out that string_to_explicit_location compares a char*
against '\0'; whereas comparing against NULL is more normal.

PR breakpoints/20653:
* location.c (string_to_explicit_location): Use NULL, not '\0'.
