Created attachment 121814 [details] Patch that fixes the problem The problem is that 'LLVMInstrumentation' needs to be linked as well, so scons/llvm.py needs to be changed for LLVM 3.7.x. I attached a patch that fixes the problem.
This has been fixed in https://cgit.freedesktop.org/mesa/mesa/commit/?id=a5256012ef8ea31bc8025fc72193a9772372c9a1 We could crossport it to the 11.1 branch, but I'm not sure if there will be another patch release. There is a 11.2 coming soon.
There will be at least another to versions for the 11.1 branch. Thanks for the report - I'll pick the patch for the next release.
And mesa 11.1.3 is out (announcement comming in a second0. Sorry for the delay.
