...tion: %a = alloca [10 x i32] This is different than the type of instruction generated by the AllocaInst constructor, which is of the type: %a = alloca i32, i32 10 Now, how do I go about extracting '10' as the array size from the first alloca instruction? isArrayAllocation returns false and getArraySize returns 1.

...lace an instruction, and I'm not quite sure of what to do. I have the following snippet of code: switch((*I)->getOpcode()) { case Instruction::Malloc: { AllocaInst *AI; AI = new AllocaInst(cast<AllocationInst>(*I)->getAllocatedType(), cast<AllocationInst>(*I)->getArraySize()); (*I)->replaceAllUsesWith(AI); // (*I)->dropAllReferences(); // (*I)->getParent()->getInstList().erase(*I); // delete (*I); // delete(AI); } break; running the code will report: Leaked objects found: after running pass 'move memory objects from the heap to the stack...

Hi, I'm gonna try to give some feedback, but I have only been working with LLVM for a few days, so don't take what I'm saying without verifying :-) > BasicBlock *ProgSlicer::CloneBasicBlock(const BasicBlock *BB, > DenseMap<const Value*, Value*> &ValueMap, > const char *NameSuffix, Function *F) { > > BasicBlock

Hi all, I am trying to write a pass where i am creating a clone of a function (the only difference being, the new function returns void , instead of any value). I am creating a new Function Type with a void return type (rest being the same as original function), and using this i am creating a new function body. Then, i clone the body of the old function into new function, but when ever i
