Hi, I am using llvm-3.8 for my project. Following is my getAnalysisUsage() method: virtual void getAnalysisUsage(AnalysisUsage &AU) const override { AU.setPreservesAll(); AU.addRequired<X>(); AU.addRequired<Y>(); AU.addRequired<Z>(); } Now, if I call getAnalysis<X>(*F), instead of invoking just the X pass, all the passes, i.e., X, Y and Z are being

Hi, I am wondering if anyone could run ArrayBoundChecks located in SafeCode-llvm37 (https://github.com/jtcriswell/safecode-llvm37) on llvm-3.8? Thanks. Syed -- Rafi

Hi, I am wondering if there is anything like def-use chain which finds all the instructions of a function where a particular value is defined? Thanks. -- Rafi
