I tried to build LLVM with script run.sh inside gg/examples/llvm folder and got an error:

No build type selected.  You need to pass -DCMAKE_BUILD_TYPE=<type> in
  order to configure LLVM.

After that i added flag to cmake command inside run.sh:
gg infer cmake -DCMAKE_BUILD_TYPE=RelWithDebInfo ../llvm-project/llvm

and got error:
gcc: unknown gcc flag: -mavx512vl
Does anyone know what this problem is?

gcc version 7.5
