I build llvm with `cmake -DCMAKE_BUILD_TYPE=Debug -DLLVM_TARGETS_TO_BUILD=X86 -DLLVM_ENABLE_PROJECTS=clang  ../llvm`
I have make a mini reproduce example at https://github.com/gou4shi1/mini-repro-pass
you can build this example with `mkdir build && cd build && cmake -DCMAKE_BUILD_TYPE=Debug .. && make`
you can run this example with `opt -load-pass-plugin=ttttt/ttttt.so -passes="ttttt" ../test/add100.ll`
