LLVM fails to build
With the configure script:
cmake -G"Unix Makefiles" -DLLVM_BUILD_LLVM_DYLIB:STRING=ON
-DLLVM_LINK_LLVM_DYLIB=ON -DLLVM_ENABLE_LIBEDIT=OFF
-DCMAKE_BUILD_TYPE:STRING=RELEASE -DCLANG_DEFAULT_LINKER:STRING=lld

-DLLVM_ENABLE_WERROR=ON -DCMAKE_CXX_FLAGS=\'-Wno-error=pedantic\' \llvm
The error is:
llvm/lib/XRay/BlockVerifier.cpp: In member function ‘llvm::Error
llvm::xray::BlockVerifier::transition(llvm::xray::BlockVerifier::State)’:
llvm/lib/XRay/BlockVerifier.cpp:97:49: error: converting to ‘const
std::tuple<llvm::xray::BlockVerifier::State, std::bitset<11ul> >’ from
