Hi all, While working on a loadable Alias Analysis module pass, I'm running into the following issue: I'm finding my pass queried for results after it has had 'releaseMemory' called on it and its dependencies, but before runOnModule is called again (on my pass or its deps). As you might expect, this makes my pass rather unhappy (and I think correctly so). This happens with LICM

In order to detect whether CallSite is present in innermost loop, do I need to insert logic from LoopInfo pass for collecting loops, within a CallGraphSCC pass?   Is there any other approach for this?   Regards, Pankaj -------------- next part -------------- An HTML attachment was scrubbed...

Dear All, I'm currently upgrading SAFECode to the LLVM 2.7 API. I'm getting some strange errors in LLVM Passes that use analysis groups and multiple inheritance. To create analysis groups in LLVM 2.6, I would first create a base class for the analysis group and then another class that inherited from both ModulePass and the analysis group base class. That worked in LLVM 2.6, but

Hi, There are two relevant hooks for you immutable pass: 1) releaseMemory() 2) doFinalization() Are you looking at the first one? I think you should act on the second instead and it should solve your issue. — Mehdi > On Dec 8, 2016, at 10:58 AM, Maxime Chevalier-Boisvert via llvm-dev <llvm-dev at lists.llvm.org> wrote: > > We have our own subtarget, with its own pipeline

Hi, I have problems to estimate the loop exit count of a simple loop with the ScalarEvolution class. simple loop: ...... int a = 0; for(int i; i < 10; ++i){ a = a + 1; }; ...... For the loop analyzation I use the ScalarEvolution class with the following initialization: ...... void analysis(Function* func) DominatorTree DT = DominatorTree(); DT.recalculate(*func);

Hi, I am trying to write an LLVM project, using LLVM 2.9. My passes are defined as follows, where the Pass2 requires Pass1. namespace llvm { class BaseClass : public ModulePass { // Name for printing const char* printname; protected: BaseClass(char id, const char* name) : ModulePass(id),printname(name){ } }; class Pass1 : public BaseClass { public: static char ID; Pass1() :

Hi, I am going to write a module pass (say, P) that uses function level analysis (say, A). Suppose, I analyze two different functions during the P pass: bool P::runOnModule(Module &M) { ... A &X = getAnalysis<A>(F1); ... A &Y = getAnalysis<A>(F2); ... } Will X and Y reference the same object here? It's not a problem for me, as I don't need results of

Hi! I am trying to develop an LLVM tool which can apply different optimizations for selected functions. For example, I want to apply an optimization onto one function but not for another one. I am using the standard optimizations available in LLVM. That is the runOnModule function I have written: bool ComplNewBBFuncs::runOnModule(Module &M) { Function *Main =

Hi Chris, Thanks for the reply. I am actually interested in using the Intervals Analysis mainly to be able to do Region based analysis. In fact, I found that the way Intervals are defined mirror exactly the definition of a Region in the second edition of the Dragon Book (Section 9.7 on Region-Based Analysis), so it will be great if the Intervals related code still lives on in LLVM :).
