Note that the syntactic binding of C++11 attributes is different from that 
of GNU attributes in various cases, so the front end will need to track 
separately what attributes of each syntax have been used in various 
places.

If this feature is going to be used also for extended GNU attributes, it can be
done via a special extension:

[[gnu init_priority(200)]]
[[gnu format(printf, 2, 3)]]

would be same as:

__attribute__ ((init_priority (200)))
__attribute__ ((format(printf, 2, 3)))

Some standard attributes can be also implemented as alias to existing gnu
attributes, for example [[gnu noreturn]] would be the same as [[noreturn]].

Currently the only standard attributes are "noreturn" and "carries_dependency".
They don't get any arguments, so I don't think the difference to current
attribute syntax matters.

There's no need for an extension, the grammar allows
[[gnu::init_priority(200)]]

A candidate implementation patch for this has been posted to
http://gcc.gnu.org/ml/gcc-patches/2012-07/msg01348.html

@Joseph:
Thank you for the note.  I believe the patch handles this, unless I have
forgotten things.

@Michal Malecki / Jonathan Wakely
The scoped attributes syntax [[gnu::priority(200)]] is now supported.  The
patch has put all the GNU attributes in the "gnu" namespace by default.  So now
whenever one writes __attribute__((priority(200))), the priority attribute is
looked up from or put into the "gnu" namespace.

We'll see what comes out of the discussion that arises from the patch
submission.

Looks nice. Is that a big deal if you also make a standard [[noreturn]]
attribute simply an alias to [[gnu::noreturn]]? As far as I know the standard,
they should behave exactly the same way.

Another thing is that I think this should work, according to the standard:

void quit [[gnu::noreturn]] () { throw 0; }

And it doesn't with this patch. Of course, [[gnu::noreturn]] void quit()...
works and is more intuitive, but both are required by the standard. I guess the
difference is when you'd do this:

int quit [[noreturn]](), pass(); // pass does return!

while here both are noreturn:

[[noreturn]] int quit(), pass();

New Revision: 192199

URL: http://gcc.gnu.org/viewcvs?root=gcc&view=rev&rev=192199
Log:
PR c++/53528 C++11 attribute support

This patch implements the c++-11 generalized attributes, described in
the N2761 paper[1].

The idea is to modify the front-end to accept the new attribute syntax
(including alignas expressions) and to build an internal
representation similar to the one we already have for GNU attributes.

This lets us re-use our existing GNU attribute mechanisms to support
the generalized c++11 attributes.

The patch does change the existing internal representation to support
scoped attribute (aka attributes with namespaces), which is a concept
that doesn't exist in GNU attributes.  I have thus put all existing
GNU extension attributes into the "gnu" namespace.  For instance, in
C++-11, the "unused" attribute would be represented as
"[[gnu::unused]]".  Because there is no syntax for scoped attributes
in C, writting "__attribute__((unused))" unconditionnally refers to
the "unused" attribute in the "gnu" namespace.

Note that this patch follows a conservative understanding of the
specification by disallowing attributes appertaining to types, unless
they apply to a type definition.

Tested on x86_64-unknown-linux-gnu and powerpc64-unknown-linux-gnu.

[Bug c++/53528] Support C++11 generalized attributes

Sorry Michal for getting to your comment this late.

"ethouris at gmail dot com" <gcc-bugzilla@gcc.gnu.org> a écrit:

> Looks nice. Is that a big deal if you also make a standard [[noreturn]]
> attribute simply an alias to [[gnu::noreturn]]?

The patch as it is focused on bringing in the core support for c++11
attributes.  Supporting some attributes in particular is left as a
follow-up to come up later.  An exception to this is that the patch also
supports alignas expressions, but that is just because it was needed to
complete the support of the attributes syntax.

> As far as I know the standard, they should behave exactly the same
> way.

I haven't looked at the details yet, but I think you are correct.

I think it works with the version of the patch that I just committed.
