[llvm-dev] LLVM-3.8.0 libcxx in-tree build fails with cmath error ::signbit has not been declared
Greetings!
I have been building llvm-3.6.x, 3.7.1 and 3.7.2 with (glibc-2.12.1,
binutils-2.24, gcc-4.9.2) almost same set if CMake flags.
However while building LLVM-3.8.0 using same CMake flags I am observing
projects/libcxx/include/cmath errors...
...'::signbit' has not been declared
...'::fpclassify' has not been declared
...'::isfinite' has not been declared
...
My environment is...
Glibc-2.12.1
Binutils-2.24
Gcc-4.92.
Llvm-3.8.0
Cmake flags...

-DCMAKE_BUILD_TYPE="Release" \
-DCMAKE_CXX_COMPILER=$GCC_ROOT/bin/g++ \

Any suggestions?
Thank you in advance.
