Huh, I just tried to rebuild things with:
-DLLVM_BUILD_LLVM_DYLIB=1 -DLLVM_LINK_LLVM_DYLIB=1 -DLLVM_APPEND_VC_REV=ON
glxinfo works fine afterwords, but I get the following error when I
try to run opencl programs:
CommandLine Error: Option 'help-list' registered more than once!
LLVM ERROR: inconsistency in registered CommandLine options
I can go back to one of my other build configurations, but it's
looking like something in that is causing multiple
registrations/initializations of some llvm components.
