I used these options: dri-drivers=r200 gallium-drivers=swrast vulkan-drivers=amd osmesa=gallium platforms=x11,wayland,drm glx=dri gles1=false gles2=false valgrind=false libunwind=false selinux=false using llvm-5.0.0; I also tried 5.0.1 and 6 gcc-7.2.0 I got something similar trying mesa-17.3, however the autotools build works in that case.
I'm having trouble reproducing your problem. I have gcc 7.2.0 and LLVM 5.0.0 and with the same options: CFLAGS="-march=native -mtune=native -m64 -pipe -O3" CXXFLAGS="-march=native -mtune=native -m64 -pipe -O3" meson build -Ddri-drivers=r200 -Dgallium-drivers=swrast -Dvulkan-drivers=amd -Dplatforms=x11,wayland,drm -Dglx=dri -Dgles1=false -Dgles2=false -Dvalgrind=false -Dlibunwind=false -Dselinux=false -Dosmesa=gallium It compiles and links fine for me. As an aside, since you're passing -O3, you should also pass --buildtype=plain, so that meson doesn't add -g and -O options. Two questions for you: Are you compiling LLVM yourself? Does the build work with autotools?
Also, I noticed you're using meson from git, are you building with upstream master, or do you have additional patches?
1. I reverted to meson-0.43.0 built from the release tarball. 2. I am now using llvm-5.0.0 built from the release tarball, with the following options: -DLLVM_ENABLE_ZLIB=1 -DLLVM_ENABLE_FFI=1 -DLLVM_TARGETS_TO_BUILD=AMDGPU;X86 -DBUILD_SHARED_LIBS=1 -DCMAKE_BUILD_TYPE=RELEASE INSTALL_PREFIX=/usr 3. I now specify buildtype=plain the mesa build still fails in the same way using git commit 57372c5a42969afe6c7afd6a0389a92e3e1a5178 4. I will now try to build the same code using autotools. I know that the 17.3 branch builds correctly using autotools.
(In reply to tjbugs from comment #3) > [...] -DBUILD_SHARED_LIBS=1 [...] Don't enable BUILD_SHARED_LIBS, it's only for LLVM developers. Enable LLVM_LINK_LLVM_DYLIB instead.

I rebuilt llvm with LLVM_LINK_LLVM_DYLIB. That now installs lots of .sa libraries and an enormous /usr/lib/libLLVM-5.0.so I then auccessfully rebuilt mesa using autotools, but the mesaon build still fails, although with a much shorter list of link libraries.

I can reproduce on Fedora 27 and Fedora 28 (rawhide) with various LLVM versions from 3.9 onwards. What info could be helpful?

Can you try building with git tip again? A patch just landed that fixes the way the meson build calculates the LLVM version string for the pre-processor. I'm not sure if that will fix it, but it's worth trying. If it doesn't I'll install fedora and see if I can reproduce and fix it.
