I did hit that issue as well, but I have C++11 forced on my SPIR-V

I guess adding the whitespace will still result in code that works with
older
C++ version, so the fix can still be accepted even if we do not plan to
switch
to C++11 by default.


Sure, the patch looks fine, but I wonder how he did hit that issue. :-)

Anyway, if this doesn't break compilation without c++11, this patch is:

Nouveau doesn't use c++11 except the codegen part.
How do you hit that issue? Pretty sure that you forced c++11, right?

I can't reproduce that compilation error with clang 3.9 btw.

Building swr also seems to be adding -std=c++11 to the nouveau portion
of the build. Can you try a clang build with this configure statement?

./autogen.sh --with-dri-drivers= --with-gallium-drivers=nouveau,swr

Yes, I'll do.

Yes, you are right, swr adds -std=c++11.
Feel free to push the patch.

Thanks.
