Hi all, When writing my custom passes, I often emit log messages to llvm::errs() like so: llvm::errs() << "Could not handle instruction: " << *Inst << std::endl; where Inst is a pointer to an Instruction. I've profiled my code and found that this way of printing an Instruction takes a very long time: indeed, it is the bottleneck of my pass. Of course, I could

Hi there, I am wondering how I can prevent the LLVM from re-ordering the added local variables during instrumentation? Because, during the instrumentation, I add some metadata to some local variables, exactly next to it, and the generated bitcode looks good. However, when it is executed, basically the stack is formed as all original local variables are located next to each other, and then all the

Hi Tim, Thanks for your reply. However, I have seen that addressSanitizer has done this by placing redzones around each local variable. But i have not figured out yet how they have done it, I was wondering if there is a switch or a method by which I can reset the slotNumbering given to each instruction. By doing so, LLVM would place them in the expected order I guess.
