Comparing C11 compilers

[Quentin Pope]

I have been searching on Google for reviews and comparisons of available
C11 compilers, and general information on degree of compliance and likely
roll out schedules for major vendors as they update their implementations
in accordance with the new standard.

However, I've found very little information on this topic!

Which C11 compilers are people here using? Have you had any problems with
the new features? Does anyone have information on vendors' plans (esp gcc,
Intel)?

Thanks

Did you see http://gcc.gnu.org/gcc-4.7/changes.html, which lists
changes for the upcoming GCC 4.7 release:

C

There is support for some more features from the C11 revision of
the ISO C standard. GCC now accepts the options -std=c11 and
-std=gnu11, in addition to the previous -std=c1x and -std=gnu1x.

* Unicode strings (previously supported only with options such
as -std=gnu11, now supported with -std=c11), and the
predefined macros __STDC_UTF_16__ and __STDC_UTF_32__.

* Nonreturning functions (_Noreturn and <stdnoreturn.h>).

* Alignment support (_Alignas, _Alignof, max_align_t,
<stdalign.h>).

* A built-in function __builtin_complex is provided to support
C library implementation of the CMPLX family of macros.

i had been experimenting with 3 compilers for C++11 (sorry - they are
still C++0x ). it looks like this:
1. GCC - most major features are there. many small things are missing
though (list of features can be found on GCC's site). bugs still happen too.
2. Visual (Microsoft) - i'd say that less than a half of what GCC supports.
3. ICC (Intel's) - very limited (basic) support.

The question was about C11, not C++11.

I am not aware of any comparisons other than the ones which are displayed in
each compiler's site.

It would be nice if there was an objective review on this issue. Maybe it
is possible to put together a C11 compliance test and then host the results
somewhere, such as a wiki from wikia.

At this moment I'm not able to do this, and I'm affraid it would take a bit
of time and work to do it right. Is anyone interested in contributing to
this?
