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` Repository: rL LLVM CHANGES SINCE LAST ACTION https://reviews.llvm.org/D54978/new/ https://reviews.llvm.org/D54978 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
