Optimizing accesses to Globals with -fpie -pie:
With -pie and x86, the linker complains if it sees a PC-relative relocation
to access a global as it expects a GOTPCREL relocation. This is really not
necessary as the linker could use a copy relocation to get around it. This
patch enables copy relocations with pie.
Context:
This is useful because currently the GCC compiler with option -fpie makes
every extern global access go through the GOT. That is because the compiler
cannot tell if a global will end up being defined in the executable or not
and is conservative. This ends up hurting performance when the binary is linked
as mostly static where most of the globals do end up being defined in the
executable. By allowing copy relocs with fPIE, the compiler need not generate
a GOTPCREL(GOT access) for any global access. It can safely assume that all
globals will be defined in the executable and generate a PC-relative access
instead. Gold can then create a copy reloc for only the undefined globals.

mi: Use the value in mi_console_file->quote as the quoting character
In mi_interpreter_init, multiple MI consoles/channels are created and a quoting

hardcoded to ". We might never use another quoting character than an actual

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.

Relax the pattern in dwzbuildid.exp
Hi,

else
error (_("No symbol \"%s\" in current context."),

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

This patch is to relax the pattern to match the both cases that glibc build

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;

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.

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.

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.

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 "" ...

The "QNonStop" feature is associated with the PACKET_QNonStop packet,
with a default of PACKET_DISABLE, so GDB should not be sending the
packet at all.
The patch that introduced the regression decoupled packet_config's
'detect' and 'support' fields, making the former (an auto_boolean)
purely the associated "set remote foo-packet" command's variable. In
the example above, the packet config's 'supported' field does end up
correctly set to PACKET_DISABLE. However, nothing is presently
initializing packet configs that don't actually have a command
associated. Those configs's 'detect' field then ends up set to
AUTO_BOOLEAN_TRUE, simply because that happens to be 0. This forces
GDB to assume the packet is supported, irrespective of what the target
claims it supports, just like if the user had done "set remote
foo-packet on" (this being the associated command, if there was one).
Ideally, all packet configs would have a command associated. While
that isn't true, make sure all packet configs are initialized, even if
no command is associated, and add an assertion that prevents adding
more packets/features without an associated command.

dwarf2read.c::read_subrange_type: Handle dynamic lower bounds
Currently, read_subrange_type handles dynamicity only in the case of
the upper bound, and assumes that the lower bound is always static.
That's rooted in the fact that dynamicity was added to support C99
variable-length arrays, where the lower bound is always zero, and
therefore never dynamic. But the lower bound can, in fact, be dynamic
in other languages such as Ada.
Consider for instance the following declaration in Ada...
type Array_Type is array (L .. U) of Natural;
... where L and U are parameters of the function where the declaration
above was made, and whose value are 5 and 10. Currently, the debugger
is able to print the value of the upper bound correctly, but not the
lower bound:
(gdb) ptype array_type
type = array (1 .. 10) of natural

was 10, we would see the following:

type = array (5 .. 10) of natural
(gdb) maintenance set ada ignore-descriptive-types

This patch enhances ada_discrete_type_{high,low}_bound to resolve

Enhance dwarfread.c::resolve_dynamic_type to resolve dynamic ranges
This change breaks down the resolve_dynamic_bounds function which
works only on arrays and its index range types into two functions,
one that resolves range types, and one that resolves arrays (using
the new routine to resolve the array's index range type). The
is_dynamic_type and resolve_dynamic_type function are then re-organized
to handle range types as well.
One small change worth mentioning is the fact that, now that range
types are resolved on their own (rather than in the limited context
of array index types), the resolved range types are created from
a copy of the dynamic range type, rather than from scratch (first
parameter of create_range_type). This allows us to preserve as many
original properties in the resolved type as possible (Eg. the type's
name).
This is preparation work that will help better support dynamic range
types for languages that allow the declaration of such types (Eg. Ada).

ada-varobj.c::ada_varobj_describe_simple_array_child only ever gets
called after all GNAT encodings have been applied to (parent_value,
parent_type). So there is no point in redoing it partially by
checking for parallel XA types again.
gdb/ChangeLog:
* ada-varobj.c (ada_varobj_describe_simple_array_child): Remove
handling of parallel ___XA types.

remove unnecessary second call to static_unwrap_type in ada_evaluate_subexp
In ada-lang.c::ada_evaluate_subexp, case OP_VAR_VALUE, when noside
is EVAL_AVOID_SIDE_EFFECTS, the first thing we do is set type as
follow:
type = static_unwrap_type (SYMBOL_TYPE (exp->elts[pc + 2].symbol));
Later on in the same block, we make the same call:
return value_zero
(to_static_fixed_type
(static_unwrap_type (SYMBOL_TYPE (exp->elts[pc + 2].symbol))),
not_lval);
This patch removes the second call, since it should result in the same
type being returned, so no point in making that call again.
gdb/ChangeLog:
* ada-lang.c (ada_evaluate_subexp) <OP_VAR_VALUE>: Remove
unnecessary second call to static_unwrap_type.

This fixes a bootstrapping problem with gcc 4.9 in an x86 PE environment.
The problem was that references to weak function symbols were being
incorrectly biased by definition's offset.

Make "set disassemble-next-line on" can work with DUMMY_FRAME, SIGTRAMP_FRAME and ARCH_FRAME
When GDB debug DUMMY_FRAME, SIGTRAMP_FRAME and ARCH_FRAME, even if
"set disassemble-next-line on", it will not output the asm code:
(gdb) set disassemble-next-line on

So make this patch make they can work together, it will become:
