Dear llvm guys, I am trying to add the BreakCriticalEdges pass to my application. I tried to add it to the PNE pass (e.g. PHIElimination.cpp - AU.addRequiredID(BreakCriticalEdgesID); ), but I get this error: llc -f -regalloc=simple Base1Sum.bc -o simple.s ----------------------------------------------- llc: PassManagerT.h:387: void llvm::PassManagerT<Trait>::markPassUsed(const

Hi all, Why are these two passes conflicting: UnifyFunctionExitNodes and LowerSwitch? AU.addRequired(LowerSwitchID) works, so does AU.addRequired<unifyFunctionExitNodes>(), but the two together don't... opt: PassManagerT.h:387: void llvm::PassManagerT<Trait>::markPassUsed(const llvm::PassInfo*, llvm::Pass*) [with Trait = llvm::MTraits]: Assertion `getAnalysisOrNullUp(P)

Hi, I have two function passes: AvailOut and HashGVN. AvailOut needs to use HashGVN. And they're built in the same shared object file. But addRequired<HashGVN> fails with this error: # opt -load ../../../build/Release/lib/LLVMGVN.so -hashgvn -availout --debug-pass=Structure <basic.s.bc >basic.out.bc opt: /proj/tbres/shanth/llvm/llvm-1.9/lib/VMCore/PassManagerT.h:387: void

Dear guys, I need help fixing a little piece of code. I have a pass that I really want to execute after the TwoAddressinstructionPass. But if I write "AU.addRequiredID(TwoAddressInstructionPassID);" in my pass' getAnalysisUsage, I end up getting the infamous: PassManagerT.h:387: failed assertion `getAnalysisOrNullUp(P) &&

Hi > Right it does. However, does something *else* require MParSchedule? If > so, what? Ok, i am writing on a different backend based on the cbackend. The test usage of this pass looks like this: void getAnalysisUsage(AnalysisUsage &AU) const { AU.addRequired<LoopInfo>(); AU.addRequired<MParSchedule>(); AU.setPreservesAll(); } and then in the

Hi Thanks for all your feedback. I just found the reason for the compile failure for my analysis pass: I had to add my object to the namespace llvm instead of anonymous. This took me some time since i was looking for an linking failure... but as errors go i should have looked at the error message a little closer. So for all those trying to add an analysis path: * add the object name to the

Hi, I have a hopefully quick question. I'm writing a Pass that needs to see a whole module at a time and keep some state, so I subclassed Pass. However, I want to be able to see the Loops in each Function. Roughly, here's what I want: virtual bool run(Module &M){ // do stuff... for (Module::iterator I = M.begin(), E = M.end(); I != E; ++I){ if(! I->isExternal())

Dear LLVM guys, I am getting an error with my pass implementation, and I cannot figure it out. Basically, I've implemented part of a register allocation algorithm, but I am having problems to set the passes correctly. For instance, for this program below, the following error message is produced: .c ----------------------| .bc ---------------------------------

Dear LLVM guys, I've solved my problem with the passes, and compiled my first code using the new register allocator! Debugging was quite easy, using gdb. The problem was that I was forgetting to initialize the array that records the physical registers ever used (MachineFunction::UsedPhysRegs). This is a very minor thing, but I would suggest asserting that the vector has been initialized
