Based on the discussion at:
<https://sourceware.org/ml/gdb-patches/2013-09/msg00301.html>
<https://sourceware.org/ml/gdb-patches/2013-09/msg00383.html>
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.

Rework value_of_register in terms of value_of_register_lazy.
I noticed that value_of_register (used for getting values _of_
registers ($pc, $rax, etc.), rather than variables _in_ registers),
kind of builds a franken-value, by propagating the lval and address of
the frame register value, but not the entire location, like necessary
for lval_computed (if some unwinder ever returns that, the resulting
value will misbehave). This gets in the way of printing optimized out
(not saved) lval_registers differently from other optimized out
values, as it doesn't make sure the resulting value is lval_register.
I started out by just doing something like:
- VALUE_LVAL (reg_val) = lval;
- set_value_address (reg_val, addr);
+ VALUE_LVAL (reg_val) = lval_register;
... just like value_of_register_lazy below. That's sufficient to fix
the issue.
Then I noticed this is using frame_register, which we should avoid
nowadays, for it returns elements of a value, but not all that's
sometimes necessary (unavailable-ness is all or nothing with it, for
instance), and considered using get_frame_register_value instead
(which returns a struct value), and value_contents_copy, just like
value_fetch_lazy's handling of lval_register. But at that point, I
realized we might as well just defer all that work to
value_of_register_lazy/value_fetch_lazy...
Doing it this way adds a frame_find_by_id lookup (from within
value_fetch_lazy), while we already have a frame pointer handy in
value_of_register. I considered factoring out the lazy register
fetching out of value_fetch_lazy, into a function that takes a frame
pointer and call that instead, avoiding the lookup, but then it looked
like too much complication for an early optimization, and went back to
keeping it simple.
Tested on x86_64 Fedora 17.

[TUI] Rewrite register-changed decision bits.
I stumbled on the TUI's register-changed decision code before (used to
decided whether the register should be highlighted in the register
window), for it is trying to compare all the different possible states
and contents or previous/current register contents, and as such may
need updating whenever the value machinery changes to have more state.
It's just much simpler and more future proof to compare the
previous/current printable representation instead.
The bit in tui_register_format that returns early if the register has
no name gets a bit in the way of the new prototype (what to return in
that case? NULL, empty string, etc.?). Fortunately, that check isn't
really necessary. All the callers will have already skipped unnamed
registers.

[PR tui/15933] TUI shows registers of the wrong frame the first time
I've stumbled on this by inspection.
When the TUI's register window is first displayed, it always shows the
registers of the current frame, instead of of the selected frame,
which is obviously bogus.
E.g.,
(gdb) step # into "function"
(gdb) up
(gdb) tui reg general # or C-x 2, C-x 2
shows the registers of "function", rather than the caller's.
A subsequent:
(gdb) frame
or
(gdb) down
(gdb) up
can be used as workaround to "fix" it.
