'loom-nv-debug' registered more than once

[Mohannadcse]

I receive this error while running loom.

opt: CommandLine Error: Option 'loom-nv-debug' registered more than once!
LLVM ERROR: inconsistency in registered CommandLine options

I built Loom using LLVM 3.8. Where I used a precompiled version and I built LLVM from source for building Loom.

I used this command for building Loom
cmake -G Ninja -DCMAKE_CXX_COMPILER=lvm/Release/bin/clang++ -DCMAKE_C_COMPILER=/llvm/Release/bin/clang-3.8 -D CMAKE_BUILD_TYPE=Release ..

@Mohannadcse Could you send me a copy of the policy file you are using? And maybe a small example I could test against?

[Mohannadcse]

I built based on the Wisconsin branch.
Here is the policy: really_small.policy.txt

However, this error appears even before running the policy, just by running the help command opt -load /path/to/LLVMLoom.so -help | grep loom

@Mohannadcse I do not get the same error in the Master branch of Loom. Most of the University of Wisconsin work was merge into Loom last year. Is there anything specifically in that branch that you need that is not the Loom Master branch?
