f989a1c8ec rename "set debugvarobj" to "set debug varobj" 
I think "set debugvarobj" has the wrong name.
It ought to be "set debug varobj", like gdb's other debug settings.

This patch makes the change.

I chose not to install deprecated aliases, since this is only a debug
setting; but if someone feels strongly about it I will add them.

Built and regtested on x86-64 Fedora 20.

f7730599d8 Fix an issue with "Rearrange MIPS INSN* masks" patch. 
This fixes an issue with Mark Shinwell's "Rearrange MIPS INSN* masks" patch
(https://sourceware.org/ml/binutils/2007-11/msg00231.html).  In the patch
the pref instruction had its membership flags changed from I4|I32|G3 to
I4_32|G3.  Unfortunately G3 was defined as being I4, which made the actual
expanded flags as: I4|I32|I4 and therefore the membership flags should have
been I4_32.  Since the patch was committed G3 was redefined to be I4|EE.  This
fix just removes I4 from G3 making the expanded membership flags for pref as
I4_32|EE.

ChangeLog:

opcodes/
	* mips-opc.c (G3): Remove I4.

5e45f04cf3 Relax the pattern in dwzbuildid.exp 
Hi,
I recently see the fail in dwzbuildid.exp below on some targets,

(gdb) print the_int
No symbol "the_int" in current context.
(gdb) FAIL: gdb.dwarf2/dwzbuildid.exp: mismatch: print the_int

Looks the pattern expects to see "No symbol table is loaded", which
is emitted in c-exp.y,

variable:       name_not_typename
....
                              if (msymbol.minsym != NULL)
                                write_exp_msymbol (pstate, msymbol);
                              else if (!have_full_symbols () && !have_partial_symbols ())
                                error (_("No symbol table is loaded.  Use the \"file\" command."));
                              else
                                error (_("No symbol \"%s\" in current context."),
                                       copy_name ($1.stoken));

it is expected to have no full symbols nor partial symbols, but something
brings full symbols or partial symbols in.  I added "maint info symtabs"
and "maint info psymtabs" in dwzbuildid.exp, and it shows symbols are from
ld.so, which has debug information.  Then, I reproduce the fail like this,

  $ make check RUNTESTFLAGS="CFLAGS_FOR_TARGET='-Wl,-rpath=${glibc_build}:${glibc_build}/math  -Wl,--dynamic-linker=${glibc_build}/elf/ld.so' dwzbuildid.exp"

${glibc_build} is the glibc build tree.  Debug information is not striped,
so the test fail.  However, if I strip debug information from libc.so, libm.so
and ld.so.  The test passes.

This patch is to relax the pattern to match the both cases that glibc build
has and has not debug information.

285ca99246 Properly handle multiple opcode prefixes 
This patch updates multiple opcode prefix processing:

1. Always print prefix together with bad opcode.

290a839c9a Partially available/unavailable data in requested range 
In gdb.trace/unavailable.exp, an action is defined to collect
struct_b.struct_a.array[2] and struct_b.struct_a.array[100],

struct StructB
{
  int d, ef;
  StructA struct_a;
  int s:1;
  static StructA static_struct_a;
  const char *string;
};

and the other files are not collected.

When GDB examine traceframe collected by the action, "struct_b" is
unavailable completely, which is wrong.

(gdb) p struct_b
$1 = <unavailable>

When GDB reads 'struct_b', it will request to read memory at struct_b's address
of length LEN.  Since struct_b.d is not collected, no 'M' block
includes the first part of the desired range, so tfile_xfer_partial returns
TARGET_XFER_UNAVAILABLE and GDB thinks the whole requested range is unavailable.

In order to fix this problem, in the iteration to 'M' blocks, we record the
lowest address of blocks within the request range.  If it has, the requested
range isn't unavailable completely.  This applies to ctf too.  With this patch
applied, the result looks good and fails in unavailable.exp is fixed.

(gdb) p struct_b
$1 = {d = <unavailable>, ef = <unavailable>, struct_a = {a = <unavailable>, b = <unavailable>, array = {<unavailable>,
<unavailable>, -1431655766, <unavailable> <repeats 97 times>, -1431655766, <unavailable> <repeats 9899 times>}, ptr = <unavailable>, bitfield = <unavailable>}, s = <unavailable>,   static static_struct_a = {a = <unavailable>, b = <unavailable>, array = {<unavailable> <repeats 10000 times>}, ptr = <unavailable>,
bitfield = <unavailable>}, string = <unavailable>}

91256dc2fb Show new created display 
When I run refactored unavailable.exp, I find
command display behaves a little different on live inferior and on
examining traceframes.  In live inferior, when command "display argc"
is typed, the value of "argc" is shown.

(gdb) display argc
1: argc = 1 '\001'

however, on tfile target, when command "display argc" is typed, the
value of "argc" is not shown.

(gdb) tfind
Found trace frame 0, tracepoint 1
    at ../../../../git/gdb/testsuite/gdb.trace/unavailable.cc:198
198       i =  (int) argc + argi + argf + argd + argstruct.memberi + argarray[1];
(gdb) display argc

I also notice that on "core" target, the value of "argc" isn't shown
either.  This difference is caused by the code below in printcmd.c:display_command,

      if (from_tty && target_has_execution)
        do_one_display (new);

Looks the value of each display is shown if the target has execution.
Source code archaeology doesn't tell much about this requirement.
However, if we type command "display" then on "core" or "tfile"
target, the value of "argc" is still displayed,

for "core" target,
(gdb) display argc
(gdb) display
1: argc = 1 '\001'

for "tfile" target,
(gdb) display argc
(gdb) display
1: argc = <unavailable>

I feel that it is not necessary to have such "target has execution"
requirement to show the value of new created display.  Auto-display is
a feature to show the value of expression frequently, has nothing to
do with whether target has execution or not.  On the other hand, GDB
has the requirement for new created display, but command "display" can
still show them, this is an inconsistency, which should be fixed.

This patch is to remove the checking to target_has_execution from the
condition.

30a1e6cc77 Extend recognized types of SDT probe's arguments 
This commit is actually an update to make the parser in
gdb/stap-probe.c be aware of all the possible prefixes that a probe
argument can have.  According to the section "Argument Format" in:

  <https://sourceware.org/systemtap/wiki/UserSpaceProbeImplementation>

The bitness of the arguments can be 8, 16, 32 or 64 bits, signed or
unsigned.  Currently GDB recognizes only 32 and 64-bit arguments.
This commit extends this.  It also provides a testcase, only for
x86_64 systems.

f33da99a54 Fix PR breakpoints/16889: gdb segfaults when printing ASM SDT arguments 
This commit fixes PR breakpoints/16889, which is about a bug that
triggers when GDB tries to parse probes whose arguments do not contain
the initial (and optional) "N@" part.  For reference sake, the de
facto format is described here:

  <https://sourceware.org/systemtap/wiki/UserSpaceProbeImplementation>

Anyway, this PR actually uncovered two bugs (related) that were
happening while parsing the arguments.  The first one was that the
parser *was* catching *some* arguments that were missing the "N@"
part, but it wasn't correctly setting the argument's type.  This was
causing a NULL pointer being dereferenced, ouch...

The second bug uncovered was that the parser was not catching all of
the cases for a probe which did not provide the "N@" part.  The fix
for that was to simplify the check that the code was making to
identify non-prefixed probes.  The code is simpler and easier to read
now.

I am also providing a testcase for this bug, only for x86_64
architectures.

5b80f00d51 gdb_load: Fix latent bugs 
In a test I was writting, I needed a procedure that would connect to
the target, and do "load", or equivalent.

Years ago, boards would override gdb_load to implement that.  Then
gdb_reload was added, and gdb_load was relaxed to allow boards avoid
the spawing and connecting to the target.  This sped up gdbserver
testing.  See
https://www.sourceware.org/ml/gdb-patches/2007-02/msg00318.html.

To actually spawn the target and load the executable on the target
side, gdb_reload was born:

 # gdb_reload -- load a file into the target.  Called before "running",
 # either the first time or after already starting the program once,
 # for remote targets.  Most files that override gdb_load should now
 # override this instead.

 proc gdb_reload { } {
     # For the benefit of existing configurations, default to gdb_load.
     # Specifying no file defaults to the executable currently being
     # debugged.
     return [gdb_load ""]
 }

Note the comment about specifying no file.  Indeed looking at
config/sid.exp, or config/monitor.exp, we see examples of that.

However, the default gdb_load itself doesn't handle the case of no
file specified.  When passed no file, it just calls gdb_file_cmd with
no file either, which ends up invocing the "file" command with no
argument, which means unloading the file and its symbols...  That
means calling gdb_reload when testing against native targets is
broken.  We don't see that today because the only call to gdb_reload
that exists today is guarded by target_info exists
gdb,do_reload_on_run.

The native-extended-gdbserver.exp board is likewise broken here.  When
[gdb_load ""] is called, the board sets the remote exec-file to "" ...

Tested on x86_64 Fedora 17, native, remote gdbserver and
extended-remote gdbserver.
