Hi,
I find "dynamic=1" appear in the result of each child of the output of
-var-list-children,

^done,numchild="2",children=[child={name="ss1.a",exp="a",numchild="0",type="struct s",thread-id="1",dynamic="1"},child={name="ss1.b",exp="b",numchild="0",type="struct s",thread-id="1",dynamic="1"}],has_more="0"
but the doc doesn't mention this. This patch is to copy the description
of "dynamic=1" here.

This patch fixes PR c++/16117.
gdb has an extension so that users can use expressions like FILE::NAME
to choose a variable of the given name from the given file. The bug
is that this extension takes precedence over ordinary C++ expressions
of the same form. You might think this is merely hypothetical, but
now that C++ headers commonly do not use an extension, it is more
common.
This patch fixes the bug by making two related changes. First, it
changes gdb to prefer the ordinary C++ meaning of a symbol over the
extended meaning. Second, it arranges for single-quoting of the
symbol to indicate a preference for the extension.
Built and regtested on x86-64 Fedora 18.

Frontend sometimes need to evaluate expressions that are
language-specific. For instance, Eclipse uses the following
expression to determine the size of an address on the target:
-data-evaluate-expression "sizeof (void*)"
Unfortunately, if the main of the program being debugged is not C,
this may not work. For instance, if the main is in Ada, you get...
-data-evaluate-expression "sizeof (void*)"
^error,msg="No definition of \"sizeof\" in current context."
... and apparently decides to stop the debugging session as a result.
The recommendation sent was to specifically set the language to C
before trying to evaluate the expression. Something such as:
1. save current language
2. set language c
3. -data-evaluate-expression "sizeof (void*)"
4. Restore language
This has the same disadvantages as the ones outlined in the "Context
Management" section of the GDB/MI documentation regarding setting
the current thread or the current frame, thus recommending the use of
general command-line switches such as --frame, or --thread instead.
This patch follows the same steps for the language, adding a similar
new command option: --language LANG. Example of use:
-data-evaluate-expression --language c "sizeof (void*)"
^done,value="4"

Rather than having -list-features report support for the GDB/MI

Note that mi_cmd_var_info_expression uses varobj_language_string,

me. With this patch applied, this problem doesn't exist, because the

Occasionaly we hear about people having problems with GDB not being
able to start programs (with "run"/"start"). GDB spawns a shell to
start the program, and most often, it'll be the case that the problem
is actually with the user's shell setup.
GDB has code to disable the use of the shell to start programs.
That's the STARTUP_WITH_SHELL macro that native targets could set to 0
in their nm.h file (though no target actually uses it nowadays).
This patch makes that setting a run-time knob instead. This will be
useful to quickly diagnose such shell issues, and might also come in
handy at other times (such as when debugging the shell itself, if you
don't have a different shell handy).

I've made modifications on infrun.c:handle_inferior_event such that

This assumption was made because the variables are mutually
exclusive, i.e., when the inferior terminates because of an uncaught
signal it is not possible for it to return. I have also made modifications
such that when a corefile is loaded, $_exitsignal gets set to the uncaught
signal that "killed" the inferior, and $_exitcode is cleared.

Currently, in some scenarios, GDB prints <optimized out> when printing
outer frame registers. An <optimized out> register is a confusing
concept. What this really means is that the register is
call-clobbered, or IOW, not saved by the callee. This patch makes GDB
say that instead.
Before patch:
(gdb) p/x $rax $1 = <optimized out>
(gdb) info registers rax
rax <optimized out>
After patch:
(gdb) p/x $rax
$1 = <not saved>
(gdb) info registers rax
rax <not saved>
However, if for some reason the debug info describes a variable as
being in such a register (**), we still want to print <optimized out>
when printing the variable. IOW, <not saved> is reserved for
inspecting registers at the machine level. The patch uses
lval_register+optimized_out to encode the not saved registers, and
makes it so that optimized out variables always end up in
!lval_register values.
** See <https://sourceware.org/ml/gdb-patches/2012-08/msg00787.html>.
Current/recent enough GCC doesn't mark variables/arguments as being in
call-clobbered registers in the ranges corresponding to function
calls, while older GCCs did. Newer GCCs will just not say where the
variable is, so GDB will end up realizing the variable is optimized
out.
frame_unwind_got_optimized creates not_lval optimized out registers,
so by default, in most cases, we'll see <optimized out>.
value_of_register is the function eval.c uses for evaluating
OP_REGISTER (again, $pc, etc.), and related bits. It isn't used for
anything else. This function makes sure to return lval_register
values. The patch makes "info registers" and the MI equivalent use it
too. I think it just makes a lot of sense, as this makes it so that
when printing machine registers ($pc, etc.), we go through a central
function.
We're likely to need a different encoding at some point, if/when we
support partially saved registers. Even then, I think
value_of_register will still be the spot to tag the intention to print
machine register values differently.
value_from_register however may also return optimized out
lval_register values, so at a couple places where we're computing a
variable's location from a dwarf expression, we convert the resulting
value away from lval_register to a regular optimized out value.

This patch adds a new convenience function called $_isvoid, whose
only purpose is to check whether an expression is void or not.
This became necessary because the new convenience variable
$_exitsignal (not yet approved) has a mutual exclusive behavior
with $_exitcode, i.e., when one is "defined" (i.e., non-void),
the other is cleared (i.e., becomes void). Doug wanted a way to
identify which variable to use, and checking for voidness is the
obvious solution.
It is worth mentioning that my first attempt, after a conversation with
Doug, was to actually implement a new $_isdefined() convenience
function. I would do that (for convenience variables) by calling
lookup_only_internalvar. However, I found a few problems:
- Whenever I called $_isdefined ($variable), $variable became defined
(with a void value), and $_isdefined always returned true.
- Then, I tried to implement $_isdefined ("variable"), and do the "$" +
"variable" inside GDB, thus making it impossible for GDB to create the
convenience variable. However, it was hard to extract the string
without having to mess with values and their idiossincrasies.
Therefore, I decided to abandon this attempt (specially because I
didn't want to spend too much time struggling with it).
Anyway, after talking to Doug again we decided that it would be easier
to implement $_isvoid, and this will probably help in cases like
<http://stackoverflow.com/questions/3744554/testing-if-a-gdb-convenience-variable-is-defined>.
I wrote a NEWS entry for it, and some new lines on the documentation.

This introduces parallel mode for the test suite.
It doesn't fully work yet in the sense that if you do a fully parallel
run, you will encounter some file-name clashes, but this has to start
somewhere, and it seemed best to add some infrastructure now, so that
you can follow along and test subsequent patches if you care to.
This patch has two parts.
First, it checks for the GDB_PARALLEL variable. If this is set (say,
on the runtest command line), then the test suite assumes "parallel
mode". In this mode, files are put into a subdirectory named after
the test. That is, for DIR/TEST.exp, the outputs are put into
./outputs/DIR/TEST/.
This first part has various follow-on changes coming in subsequent
patches. This is why the code in this patch also makes "temp" and
"cache" directories.
Second, this adds an "inotify" mode. If you have the inotifywait
command (part of inotify-tools), you can set the GDB_INOTIFY variable.
This will tell the test suite to watch for changes outside of the
allowed output directories.
This mode is useful for debugging the test suite, as it issues a
report whenever a possibly parallel-unsafe file open is done.

This whole comment is now a bit out of place. I looked into moving it
to handle_inferior_event, close to where in_solib_dynsym_resolve_code
is used, but then there are 3 such places. I then looked at
fragmenting it, pushing bits closer to the definitions of
in_solib_dynsym_resolve_code and gdbarch_skip_solib_resolver, but then
we'd lose the main advantage which is the overview. In the end, I
realized this can fit nicely as internals manual material.
This could possibly be a subsection of a new "run control", or "source
stepping" or "stepping" or some such a bit more general section, but
we can do that when we have more related content... Even the "single
stepping" section is presently empty...

In extended-remote, when GDB connects the target, but target is not
running, the TSVs are not uploaded. When GDB attaches to a process,
the TSVs are not uploaded either. However, GDBserver has some
builtin or predefined TSV to upload, such as $trace_timestamp. This
bug causes $trace_timestamp is never uploaded.

Right now there are two nightly commits to update a file in the tree
with the current date. One commit is for BFD, one is for gdb.
It seems unnecessary to me to do this twice. We can make do with a
single such commit.
This patch changes gdb in a minimal way to reuse the BFD date -- it
extracts it from bfd/version.h and changes version.in to use the
placeholder string "DATE" for those times when a date is wanted.
I propose removing the cron job that updates the version on trunk, and
then check in this patch.
For release branches, we can keep the cron job, but just tell it to
rewrite bfd/version.h. I believe this is a simple change in the
crontab -- the script will work just fine on this file.
This also moves version.in and version.h into common/, to reflect
their shared status; and updates gdbserver to use version.h besides.
