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 invoked. Could anyone help me in this regard? Thanks -- Syed

Hi, I have a doubt regarding *getAnalysisUsage.* My assumption is that, as analysis passes will not change the IR, all the passes required by an analysis pass should be preserved. Say, I have an analysis pass which requires another analysis pass called *SomeAnalysis* and I have not added *AU.addPreserved<SomeAnalysis>() *to my pass. Would the pass manager still considers the *SomeAnlaysis

Hi, I've written a couple of passes, and I intend to use them using llvm-ld (loading works fine). However, I can't seem to figure out how to put them first, i.e. before all other optimizations (inlining, internalizing, ... should only kick in after my passes). Omitting AnalysisUsage::setPreservesAll() doesn't help and there is no AnalysisUsage::invalidateAll(). Does anybody know a workaround? Kind regards, Bram Adams GH-SEL, INTEC, Ghent University (Belgium)
