f168693bc9 Remove CHECK_TYPEDEF, use check_typedef instead
I think that the CHECK_TYPEDEF macro is not necessary, and even a bit
annoying.  It makes unclear the fact that the "type" variables gets
overwritten.  It has actually bitten me a few times.  I think the
following, explicit form, is better.

  type = check_typedef (type);

This patches changes all instances of CHECK_TYPEDEF for an equivalent
call to check_typedef.  The bulk of the change was done with this sed:

  sed -i 's/CHECK_TYPEDEF (\([^)]*\));/\1 = check_typedef (\1);/' <file>.c

The ChangeLog was generated using David Malcom's generate_changelog.py.
I manually fixed those places where it gets the wrong function name,
hopefully all of them.

The patch was built-tested, and I ran a few smoke tests.

492d29ea1c Split TRY_CATCH into TRY + CATCH
This patch splits the TRY_CATCH macro into three, so that we go from
this:

~~~
  volatile gdb_exception ex;

  TRY_CATCH (ex, RETURN_MASK_ERROR)
    {
    }
  if (ex.reason < 0)
    {
    }
~~~

to this:

~~~
  TRY
    {
    }
  CATCH (ex, RETURN_MASK_ERROR)
    {
    }
  END_CATCH
~~~

Thus, we'll be getting rid of the local volatile exception object, and
declaring the caught exception in the catch block.

This allows reimplementing TRY/CATCH in terms of C++ exceptions when
building in C++ mode, while still allowing to build GDB in C mode
(using setjmp/longjmp), as a transition step.

TBC, after this patch, is it _not_ valid to have code between the TRY
and the CATCH blocks, like:

  TRY
    {
    }

  // some code here.

  CATCH (ex, RETURN_MASK_ERROR)
    {
    }
  END_CATCH

Just like it isn't valid to do that with C++'s native try/catch.

By switching to creating the exception object inside the CATCH block
scope, we can get rid of all the explicitly allocated volatile
exception objects all over the tree, and map the CATCH block more
directly to C++'s catch blocks.

The majority of the TRY_CATCH -> TRY+CATCH+END_CATCH conversion was
done with a script, rerun from scratch at every rebase, no manual
editing involved.  After the mechanical conversion, a few places
needed manual intervention, to fix preexisting cases where we were
using the exception object outside of the TRY_CATCH block, and cases
where we were using "else" after a 'if (ex.reason) < 0)' [a CATCH
after this patch].  The result was folded into this patch so that GDB
still builds at each incremental step.

END_CATCH is necessary for two reasons:

First, because we name the exception object in the CATCH block, which
requires creating a scope, which in turn must be closed somewhere.
Declaring the exception variable in the initializer field of a for
block, like:

  #define CATCH(EXCEPTION, mask) \
    for (struct gdb_exception EXCEPTION; \
         exceptions_state_mc_catch (&EXCEPTION, MASK); \
	 EXCEPTION = exception_none)

would avoid needing END_CATCH, but alas, in C mode, we build with C90,
which doesn't allow mixed declarations and code.

Second, because when TRY/CATCH are wired to real C++ try/catch, as
long as we need to handle cleanup chains, even if there's no CATCH
block that wants to catch the exception, we need for stop at every
frame in the unwind chain and run cleanups, then rethrow.  That will
be done in END_CATCH.

After we require C++, we'll still need TRY/CATCH/END_CATCH until
cleanups are completely phased out -- TRY/CATCH in C++ mode will
save/restore the current cleanup chain, like in C mode, and END_CATCH
catches otherwise uncaugh exceptions, runs cleanups and rethrows, so
that C++ cleanups and exceptions can coexist.

IMO, this still makes the TRY/CATCH code look a bit more like a
newcomer would expect, so IMO worth it even if we weren't considering
C++.

7556d4a4f6 Normalize TRY_CATCH exception handling block
This normalizes some exception catch blocks that check for ex.reason
to look like this:

~~~
  volatile gdb_exception ex;

  TRY_CATCH (ex, RETURN_MASK_ALL)
    {
      ...
    }
  if (ex.reason < 0)
    {
      ...
    }
~~~

This is a preparation step for running a script that converts all
TRY_CATCH uses to look like this instead:

~~~
  TRY
    {
      ...
    }
  CATCH (ex, RETURN_MASK_ALL)
    {
      ...
    }
  END_CATCH
~~~

The motivation for that change is being able to reimplent TRY/CATCH in
terms of C++ try/catch.

This commit makes it so that:

 - no condition other than ex.reason < 0 is checked in the if
   predicate

 - there's no "else" block to check whether no exception was caught

 - there's no code between the TRY_CATCH (TRY) block and the
   'if (ex.reason < 0)' block (CATCH).

 - the exception object is no longer referred to outside the if/catch
   block.  Note the local volatile exception objects that are
   currently defined inside functions that use TRY_CATCH will
   disappear.  In cases it's more convenient to still refer to the
   exception outside the catch block, a new non-volatile local is
   added and copy to that object is made within the catch block.

The following patches should make this all clearer.

7cf99fb1c7 Exported const objects
const works different in C vs C++.  In C++, a global "const" variable
has internal linkage by default, resulting in link errors like:

  ...
  extension.o: In function `get_ext_lang_defn(extension_language)':
  gdb/extension.c:126: undefined reference to `extension_language_guile'
  gdb/extension.c:124: undefined reference to `extension_language_guile'
  ...

The fix is to define exported const objects with "extern const".  But
that in C would not be a definition.  So we need to #ifdef C vs C++ in
this case.

EXPORTED_CONST comes from include/ansidecl.h, but in the
feature_to_c.sh case I think it's better to leave the script with no
dependencies.

2015-02-27  Pedro Alves  <palves@redhat.com>

	* cp-valprint.c (vtbl_ptr_name): Use EXPORTED_CONST.

fe978cb071 C++ keyword cleanliness, mostly auto-generated
This patch renames symbols that happen to have names which are
reserved keywords in C++.

Most of this was generated with Tromey's cxx-conversion.el script.
Some places where later hand massaged a bit, to fix formatting, etc.
And this was rebased several times meanwhile, along with re-running
the script, so re-running the script from scratch probably does not
result in the exact same output.  I don't think that matters anyway.

09e2d7c720 Move TYPE_SELF_TYPE into new field type_specific.
This patch moves TYPE_SELF_TYPE into new field type_specific.self_type
for MEMBERPTR,METHODPTR types, and into type_specific.func_stuff
for METHODs, and then updates everything to use that.
TYPE_CODE_METHOD could share some things with TYPE_CODE_FUNC
(e.g. TYPE_NO_RETURN) and it seemed simplest to keep them together.

Moving TYPE_SELF_TYPE into type_specific.func_stuff for TYPE_CODE_METHOD
is also nice because when we allocate space for function types we assume
they're TYPE_CODE_FUNCs. If TYPE_CODE_METHODs don't need or use that
space then that space would be wasted, and cleaning that up would involve
more invasive changes.

In order to catch errant uses I've added accessor functions
that do some checking.

One can no longer assign to TYPE_SELF_TYPE like this:

  TYPE_SELF_TYPE (foo) = bar;

One instead has to do:

  set_type_self_type (foo, bar);

But I've left reading of the type to the macro:

  bar = TYPE_SELF_TYPE (foo);

In order to discourage bypassing the TYPE_SELF_TYPE macro
I've named the underlying function that implements it
internal_type_self_type.

While testing this I found the stabs reader leaving methods
as TYPE_CODE_FUNCs, hitting my newly added asserts.
Since the dwarf reader smashes functions to methods (via
smash_to_method) I've done a similar thing for stabs.

9a0dc9e369 Handle partially optimized out values similarly to unavailable values
This fixes PR symtab/14604, PR symtab/14605, and Jan's test at
https://sourceware.org/ml/gdb-patches/2014-07/msg00158.html, in a tree
with bddbbed reverted:

 2014-07-22  Pedro Alves  <palves@redhat.com>

 	* value.c (allocate_optimized_out_value): Don't mark value as
 	non-lazy.

The PRs are about variables described by the DWARF as being split over
multiple registers using DWARF piece information, but some of those
registers being marked as optimised out (not saved) by a later frame.
GDB currently incorrectly mishandles these partially-optimized-out
values.

Even though we can usually tell from the debug info whether a local or
global is optimized out, handling the case of a local living in a
register that was not saved in a frame requires fetching the variable.
GDB also needs to fetch a value to tell whether parts of it are
"<unavailable>".  Given this, it's not worth it to try to avoid
fetching lazy optimized-out values based on debug info alone.

So this patch makes GDB track which chunks of a value's contents are
optimized out like it tracks <unavailable> contents.  That is, it
makes value->optimized_out be a bit range vector instead of a boolean,
and removes the struct lval_funcs check_validity and check_any_valid
hooks.

Unlike Andrew's series which this is based on (at
https://sourceware.org/ml/gdb-patches/2013-08/msg00300.html, note some
pieces have gone in since), this doesn't merge optimized out and
unavailable contents validity/availability behind a single interface,
nor does it merge the bit range vectors themselves (at least yet).
While it may be desirable to have a single entry point that returns
existence of contents irrespective of what may make them
invalid/unavailable, several places want to treat optimized out /
unavailable / etc. differently, so each spot that potentially could
use it will need to be careful considered on case-by-case basis, and
best done as a separate change.

This fixes Jan's test, because value_available_contents_eq wasn't
considering optimized out value contents.  It does now, and because of
that it's been renamed to value_contents_eq.

A new intro comment is added to value.h describing "<optimized out>",
"<not saved>" and "<unavailable>" values.

686d4defdf Print nonexisting/optimized out static fields gracefully.
With:

 struct static_struct { static int aaa; };
 struct static_struct sss;
 int main () { return 0; }

We get:

 (gdb) p sss
 $1 = {static aaa = <optimized out>}
 (gdb) p sss.aaa
 field aaa is nonexistent or has been optimized out

Note that the "field aaa ..." message is an error being thrown.

GDB is graceful everywhere else when printing optimized out values.
IOW it usually prints an <optimized out> value and puts that in the
value history.  I see no reason for here to be different, more so that
when the print the whole "containing" object (well, it's a static
field, so it's not really a container), we already print <optimized
out>.

After the patch:

 (gdb) p sss
 $1 = {static aaa = <optimized out>}
 (gdb) p sss.aaa
 $2 = <optimized out>

The value_entirely_optimized_out checks are there to preserve
behavior.  Without those, if the static field is a struct/union, GDB
would go and print its fields one by one (and print <optimized out>
for each).

Tested on x86_64 Fedora 17.

901461f8eb Print registers not saved in the frame as "<not saved>" instead of "<optimized out>".
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.

  1. The addition of 2013 to the copyright year range for every file;
  2. The use of a single year range, instead of potentially multiple
     year ranges, as approved by the FSF.

f56dcb8879 * cp-valprint.c (cp_print_value_fields): Replaced obstack_base()
method of popping recursion-detection stack with a method based on
obstack_object_size().  (Similar to the PR9167 patch below, but for
the static array obstack rather than the static member obstack.)
