I suspect you simply ran into an issue with old mesa and new llvm.
Unfortunately some usage of the c++ abi of llvm is unavoidable, and the
abi is unstable, thus breaking quite often. And we do not generally
backport such fixes to older mesa releases (if only mostly because
nobodoy would actually test them).
So you have 3 choices:
a) use newer mesa version
b) use older llvm version
I recommend this, b)
FWIW, we still use a slightly patched LLVM 3.3. But I think if you take
stock LLVM 3.5 or LLVM 3.6 it should work well.

c) backport whatever is necessary on your own.
If you really want to try c), you might actually be lucky, since it only
was a link error, it might not be an abi issue - it is possible picking
a5256012ef8ea31bc8025fc72193a9772372c9a1 from mesa git master (which
adds LLVMInstrumentation to the libs in scons/llvm.py) will do the
trick. But don't quote me on that, the other errors might be something
else entirely (c++11 abi issue? cross-compile issue?) I'm definitely no
expert on this.

Hi all,
I have been trying to compile LLVM 3.8 and Mesa 11.0.7, and I have the
final last hurdle I think to get past

I Managed to get this far, and would like to finalise it.
LLVM Version 3.8
Mesa 11.0.7
LVVM Configure line :
../*configure* -C --prefix=$HOME/mesa_win64/llvm-3.8.build
--host=x86_64-w64-mingw32 --enable-optimized --disable-assertions

Mesa Compile line :
LDFLAGS="-static -s" CXXFLAGS="-std=c++11" scons build=release
platform=windows toolchain=crossmingw machine=x86_64 libgl-gdi
Any ideas of what I am doing wrong ?
Cheers and thanks in advance for your help.
