I'm using the gvn pass, not sure about basic-aa. I've copied the code as-is from http://llvm.org/docs/tutorial/LangImpl4.html#code and added "F->addFnAttr( Attribute::ReadOnly )" after "Function *F = Function::Create(FT, Function::ExternalLinkage, Name, TheModule)". The passes it sets up are: // Set up the optimizer pipeline. Start with registering info about

Hi Rob, > I'm using the gvn pass, not sure about basic-aa. if you are using LLVM from svn then you need to specify the basic-aa analysis, otherwise gvn won't unify calls to readonly/readnone functions. This is new behaviour introduced by Dan; probably the tutorial should be updated. Ciao, Duncan. > > I've copied the code as-is from

...g llvm's commit, this pass has been replaced and superseded by Chandler's MachineBlockPlacement pass. What's unclear to me is how exactly do you add this pass to say a function pass manager? The current llvm-lua code has something like this: // ... if(OptLevel > 1) { TheFPM = new llvm::FunctionPassManager(M); // add some passes for opt1 // ... if(OptLevel > 2) { // BlockPlacement TheFPM->add(llvm::createBlockPlacementPass()); // Reassociate expressions. TheFPM->add(llvm::createReassociatePass()); // etc ... I...

Simplifycfg doesn't get run by default even with -O3, but 'opt -simplifycfg' can do it. I'm looking to add this functionality to an optimizer program that uses the llvm libraries. What's the best way to do this? I don't really mind whether it becomes available as a command line option as in opt, or I need to hardcode it as always on. To make it available as a command line
