Hi Tim, Thanks for your suggestion! I built LLVM with Debug and tried this with my custom pass. But it has the following error error: unable to load plugin '../../trace-extractor/build/TracePass.so': '../../trace-extractor/build/TracePass.so: undefined symbol: _ZTIN4llvm10ModulePassE’ Originally I used a builtin Clang in the system and it does not produce this issue. When I search for this issue on Google, it seems to be relevant to “RTTI”. But as I know LLVM is built by default -...

Hi list, I am making a simple custom pass that inserts print function calls for each instruction, so that compiled programs print out all llvm instructions on the dynamic path. For example, (conceptually) printf(“%s”, “x = x + 1”); // inserted code x = y + 1; // original code But it seems that there are some conflicts with existing optimization paths. When I compile a program with the custom

Hi list, I have several questions about LLVM pass. 1) Is building a custom LLVM pass out-of-source not recommended? The official document only contains instructions about in-source build (http://llvm.org/docs/WritingAnLLVMPass.html <http://llvm.org/docs/WritingAnLLVMPass.html>). 2) opt (ver >= 4) with custom pass libraries does not work as before. When I have a simple custom LLVM pass
