[gdbserver] Fix trace-buffer-size.exp FAILs.

I'm seeing trace-buffer-size.exp failing (with gdbserver):

  (gdb) PASS: gdb.trace/trace-buffer-size.exp: tstatus check 2
  show trace-buffer-size 4
  Requested size of trace buffer is 4.
  (gdb) PASS: gdb.trace/trace-buffer-size.exp: show trace buffer size
  set trace-buffer-size -1
  memory clobbered past end of allocated block
  Remote connection closed
  (gdb) FAIL: gdb.trace/trace-buffer-size.exp: set trace buffer size 2
  set trace-buffer-size unlimited
  (gdb) PASS: gdb.trace/trace-buffer-size.exp: set trace-buffer-size unlimited

That "memory clobbered past end of allocated block" is mcheck triggering.

Valgrind shows:

  ==23624== Invalid write of size 1
  ==23624==    at 0x418DD8: clear_trace_buffer (tracepoint.c:1443)
  ==23624==    by 0x418F3A: init_trace_buffer (tracepoint.c:1497)
  ==23624==    by 0x41D95B: cmd_bigqtbuffer_size (tracepoint.c:4061)
  ==23624==    by 0x41DEEC: handle_tracepoint_general_set (tracepoint.c:4193)

clear_trace_buffer does:

  static void
  clear_trace_buffer (void)
  {
    trace_buffer_start = trace_buffer_lo;
    trace_buffer_free = trace_buffer_lo;
    trace_buffer_end_free = trace_buffer_hi;
    trace_buffer_wrap = trace_buffer_hi;
    /* A traceframe with zeroed fields marks the end of trace data.  */
    ((struct traceframe *) trace_buffer_free)->tpnum = 0;
    ((struct traceframe *) trace_buffer_free)->data_size = 0;
    traceframe_read_count = traceframe_write_count = 0;
    traceframes_created = 0;
  }

And the tpnum+data_size fields are over 4 bytes...  This fixes it by
ensuring we allocate space at least for an EOB.  We have code
elsewhere that relies on the EOB being present (like e.g.,
find_traceframe), so this seems simplest.

server.c:gdb_read_memory: Fix error return.

When I added gdb_read_memory, with bits factored out from elsewhere, I
missed adjusting this error return.  gdb_read_memory has an interface
similar to Like GDB's xfer_partial:

> /* Read trace frame or inferior memory.  Returns the number of bytes
>   actually read, zero when no further transfer is possible, and -1 on
>   error.  Return of a positive value smaller than LEN does not
>   indicate there's no more to be read, only the end of the transfer.

Returning EIO, a positive value, is obviously bogus, for the caller
will confuse it with a successful partial transfer.

  https://sourceware.org/ml/gdb-patches/2013-08/msg00920.html

gdb/ChangeLog

        * gdb.base/code_elim1.c (my_bss_symbol): New variable added.
        (my_static_symbol): Add comment.
        (main): Reference my_bss_symbol.

MI -trace-find, print frame with LOC_AND_ADDRESS instead of SRC_AND_LOC.

When I looked for print_stack_frame calls in MI, I wondered why this
one passing down SRC_AND_LOC.  print_stack_frame does:

  /* For mi, alway print location and address.  */
  if (ui_out_is_mi_like_p (current_uiout))
    print_what = LOC_AND_ADDRESS;

So it really doesn't matter which value is passed down, but, to avoid
confusion in readers, it's better to use the MI standard here.
There's another SRC_AND_LOC in mi-interp.c, but that one makes sense.

2013-08-30  Pedro Alves  <palves@redhat.com>

* mi/mi-main.c (mi_cmd_trace_find): Use LOC_AND_ADDRESS instead of

restore_selected_frame: tweak warning.

I noticed SRC_LINE has special handling within print_stack_frame (mid
statement handling), so I audited all uses, and noticed the one in
restore_selected_frame.  I actually added this warning myself back in
2008, but reading back, I think we can do better.  "reparsed frame" is
probably confusing to users.

Old:

 warning: Couldn't restore frame #2 in current thread, at reparsed frame #0

 45         w = 0;
 (gdb)

New:

 warning: Couldn't restore frame #2 in current thread.  Bottom (innermost) frame selected:

bsd-kvm.c: Fix arguments to print_stack_frame.

1 is SRC_AND_LOC.

Then, this is passing -1 as print_level argument to print_stack_frame.
-1 is not a valid print_level value (it's a regular boolean).  But, it
used to be, before
<https://sourceware.org/ml/gdb-patches/2004-04/msg00585.html>.

patch, but went into the tree about a month after, without being
adjusted to the new interface.

thread support broken on ppc-aix.

Thread support got broken when adding 64bit support on ppc-aix.
Upon digging further, I found that the following patch...

   | * gdb_ptrace.h: Use ptrace64 instead of ptrace if HAVE_PTRACE64
   | is defined.
   | * rs6000-nat.c: Check for __ld_info64_ if compiling 64 BIT gdb.

   | (rs6000_ptrace64): Call ptace64 instead of ptracex if present.
   | * configure.ac: Check for ptrace64.
   | * configure, config.in: Regenerate.

... is responsible for this regression:

    (gdb) x /x &__n_pthreads
    0xf06a8258 <__n_pthreads>: Cannot access memory at address 0xf06a8258

Prior to the patch, we have:

    (gdb) x /x &__n_pthreads
    0xf06a8258 <__n_pthreads>: 0x00000003

The problem occurs inside rs6000_ptrace32, while calling ptrace64.
The address is given to rs6000_ptrace32 as an "int *", while
ptrace64 takes a "long long". The cast causes the address to be
sign-extended, which results in GDB trying to read the wrong address.

This patch fixes the issue by casting the address to a "uintptr_t"
instead, and letting the compiler do the implicit conversion to
"long long" in the function call.

gdb/ChangeLog:

        * rs6000-nat.c (rs6000_ptrace32): Cast "addr" to "uintptr_t"

Add options to skip unavailable locals

This is the patch to add new option '--skip-unavailable' to MI
commands '-stack-list-{locals, arguments, variables}'.  This patch
extends list_args_or_locals to add a new parameter 'skip_unavailable',
and don't list locals or arguments if values are unavailable and
'skip_unavailable' is true.

This is inspecting a trace frame (tfind mode), where only a few
locals have been collected.

-stack-list-locals, no switch vs new switch:

 -stack-list-locals --simple-values
 ^done,locals=[{name="array",type="unsigned char [2]"},{name="i",type="int",value="<unavailable>"}]
 -stack-list-locals --skip-unavailable --simple-values
 ^done,locals=[{name="array",type="unsigned char [2]"}]

-stack-list-arguments, no switch vs new switch:

 -stack-list-arguments --simple-values
 ^done,stack-args=[frame={level="0",args=[{name="j",type="int",value="4"},{name="s",type="char *",value="<unavailable>"}]},frame={level="1",args=[]}]
 -stack-list-arguments --skip-unavailable --simple-values
 ^done,stack-args=[frame={level="0",args=[{name="j",type="int",value="4"}]},frame={level="1",args=[]}]

-stack-list-variables, no switch vs new switch:

 -stack-list-variables --simple-values
 ^done,variables=[{name="j",arg="1",type="int",value="4"},{name="s",arg="1",type="char *",value="<unavailable>"},{name="array",type="unsigned char [2]"},{name="i",type="int",value="<unavailable>"}]
 -stack-list-variables --skip-unavailable --simple-values
 ^done,variables=[{name="j",arg="1",type="int",value="4"},{name="array",type="unsigned char [2]"}]
