Thank you! It did fix compiling the tests on the buildbot, but I am<br>
surprised that linking succeeded. Maybe that is because we are not<br>
using any C++11 features that require symbols from the newer<br>
libstdc++. But it would be future-proof to change clang_link_shared()<br>
to use CMAKE_CXX_FLAGS as well.<br></blockquote><div><br></div><div>Is there really a logic in Clang that would choose between old and newer libstdc++ versions</div><div>depending on the value of -std= flag?</div><div><br>
</div><div>I hope to get rid of clang_compile and clang_link_shared horridness soon by switching</div><div>to LLVM_BUILD_EXTERNAL_COMPILER_RT=ON that would use just-built Clang to configure/build compiler-rt.</div><div><br>
</div><div>So, your use case might be interesting. Can you build with -DLLVM_BUILD_EXTERNAL_COMPILER_RT=ON and</div><div>check if "make check-compiler-rt" works for you? If not, then we'd have to propagate *some* CMAKE_CXX_FLAGS</div>
<div>to configuration step of compiler-rt project, but we won't need most of the extra flags stuffed into CMAKE_CXX_FLAGS</div><div>by LLVM/Clang CMake files.
