I've been slowly trying to make Clang C++14 clean. I think most of the<br>
actual changes needed for Clang are in place now (the big one was<br>
making C++14 mode friendlier to imaginary constants) and the rest is<br>
fixing up tests.<br>
<br>
I think most of the test changes are because the wording on how the<br>
arguments to "operator new" get treated (promotion etc) was changed.<br>
I've attached a WiP diff here for reference. Unfortunately it's not<br>
even complete and these 4 tests still fail:<br>
<br>
Clang :: CodeGenCXX/vtable-available-externally.cpp<br>
Clang :: Lexer/cxx-features.cpp<br>
Clang :: OpenMP/taskloop_reduction_codegen.cpp<br>
Clang :: OpenMP/taskloop_simd_reduction_codegen.cpp<br>
<br>
I don't even think they're particularly difficult ones, just where I<br>
happened to stop when I last looked at it. I've also got to address<br>
some review comments from Richard (I haven't forgotten) to make sure<br>
we haven't decreased C-mode OpenMP coverage.<br>
<br>
There are also a handful of bits of the test-suite that need to<br>
explicitly specify c++98.<br>
<br>
So I think the actual work needed is pretty small (and I can find time<br>
to do it, probably even this weekend or something). We just need to<br>
make the decision: C++11 or C++14 and go or no-go. My vote is go and<br>
C++14.<o:p></o:p></p>

<p class="MsoNormal">+1. I think it would also make sense to include in the Clang 5 release notes that we intend for this to be the last release that defaults to -std=gnu++98. <o:p></o:p></p>
