#2574 — Which compilers support GCC expression statements?

Hello all,

Do you know which compilers support GCC extension for "expression
statements"?
http://gcc.gnu.org/onlinedocs/gcc/Statement-Exprs.html

int x = ({
    int a = 10;
    a++;
});

I found this list online:
http://stackoverflow.com/questions/6440021/compiler-support-of-gnu-statement-expression

GCC >=3
Intel C++ Compiler >=?
Clang/LLVM >= ?
Sun Studio >= 12 (New Language Extensions)
IBM XL for z/OS (marked as IBM extension)
Open64 (as it use osprey-gcc frontend)
PathScale® EKOPath

Any more? EDG? Comeau?

Thanks a lot.
--Lorenzo

I believe Comeau and EDG must support it if Intel does; Intel and Comeau
both use an EDG front-end.

Of course, users of the EDG front end can extend it with their own
features as they desire -- the EDG code is pretty easy to hack on --
but EDG has tried pretty hard to support gcc syntax extensions for a
long time, so it almost certainly does support this one, as it's one
of the most useful (I didn't check tho).

I don't know about the list, but you can achieve something very
similar on compilers supporting C++11's lambda closures:

int x = ([]->int {
    int a = 10;
    return a++;
});

Codeplay's Offload C++ compilers (http://offload.codeplay.com/products/
offload/) support expressions statements along with many other gcc
extensions.
