Thank you for your reply Yes, I change them, so what should I do for another loops?

I don't really know what you should do since I don't know what your code does. All I know is that it's changing the function's control-flow graph. If you're not modifying the structure of the loops in the function, then you can

I am changing structure of loops, I used std::vector<> but i get same error, I can’t use FunctionPass :( On Mon, Dec 12, 2011 at 8:03 PM, John Criswell <criswell at illinois.edu>wrote: > On 12/12/11 10:25 AM, neda 8664 wrote: > > Thank you for your reply > Yes, I change them, so what should I do for another loops? > > > I don't really know what you should

i am sorry, i get this error: opt: /home/llvm/src/include/llvm/Support/CallSite.h:87: ValTy* llvm::CallSiteBase<FunTy, ValTy, UserTy, InstrTy, CallTy, InvokeTy, IterTy>::getCalledValue() const [with FunTy = const llvm::Function, ValTy = const llvm::Value, UserTy = const llvm::User, InstrTy = const llvm::Instruction, CallTy = const llvm::CallInst, InvokeTy = const llvm::InvokeInst, IterTy =

Hi all, I want to find memory dependency between CallInst instruction and other. So i used the following code: * AliasAnalysis &AA=getAnalysis<AliasAnalysis>();* * if(isa<StoreInst>(inst1)){* * ** **if(isa<CallInst>(inst2))**{* * CallInst *call_inst2= dyn_cast<CallInst>(inst2); * * if(AA.getModRefInfo(inst1,call_inst2)==mod)**{* *

Hi, I try to write a FunctionPass that, among other tasks, has to clone some loops from the current function. How can I obtain the LPPassManager in order to use the CloneLoop function. In a LoopPass this is a parameter for the runOnLoop, but how can I obtain it in a FunctionPass? I tried simply by creating a new instance : ValueMap<const Value *, Value* > VMap;

Good evening, Pierre. Here is an example to you. attached. run with -disable-lazy-comilation. It is *as-is* for Win32 but might be applicable to *-linux-elf more smartly. It does get llvm::Function* by function ptr(not name!), and clone a specialized function, and execute specialized one in the same context as parent lli. > - In a running program, can I get pointers to the llvm Module that

Hello ! I wanted to experiment with partial evaluation and llvm seems to be the right tool for this, but since I'm new to it of course I'm a bit lost ! I'll try to explain what I want to do in the simplest possible way : I have a C program. In this program, there is a function f( a,b ). I have a value A for a. I want to specialise f() so I get a function fA( b ) which is the same as

Hi I'm working on a project which needs loop-attached metadata similar to the parallel metadata discussed in here. Currently I'm trying to make the metadata get through the optimisation passes unscathed. For loop passes, I've solved that by modifying the LPPassManager to check for metadata presence before and after runOnLoop, and restoring it if necessary (assuming the loop didn't

I'm wondering if the documentation for LoopPass ( http://llvm.org/docs/WritingAnLLVMPass.html#LoopPass) is misleading or incorrect (or if I'm just missing something.) The documentation states: "The doFinalization method ... is called when the pass framework has finished calling runOnLoop<http://llvm.org/docs/WritingAnLLVMPass.html#runOnLoop> for every loop in the program being

Hi, I'm trying to write a simple pass to print out Loop invariant instructions, using the Loop::isLoopInvariant(Instruction *I) function. it is giving me false value on instructions which should be loop invariant. the code i am using is: bool MyLoopPass::runOnLoop(Loop * L, LPPassManager &lpm){ BasicBlock* lat=L->getLoopLatch(); for (BasicBlock::iterator i = lat->begin(), e =

Thanks , your suggestion was welcome and CloneLoop works without passing the LPPassManager. However, I reached another problem. When the loop to be cloned has some subloops, the subloops are not properly cloned. Some clones of the clones are created and the CFG between the cloned basic blocks of the subloops is not correctly built. There are clones like for.body.clone,

Hi, All I want to implement DSWP Which is used for parallelization of loops. For this purpose, the loop was replaced with a new basic block in main function. And new functions were created and basic blocks of Loop assigned to them.I have checked blocks and branches for Succ and Pred relation and I have not found any problems. However I get the following error: * **opt:

Hello . I would like to add new custom data type to llvm C parser, I use LLVM/Clang version 3.1. Adding new type instructions from llvm.org site are out of date (http://llvm.org/docs/ExtendingLLVM.html#type). Could you please provide me with guidance?

Hello; I wrote this simple loop pass to collect the number of instructions in each loop of the program. The code is as follows- #define DEBUG_TYPE "loopinst" #include "llvm/Pass.h" #include "llvm/Analysis/LoopPass.h" #include "llvm/Support/raw_ostream.h" #include "llvm/ADT/Statistic.h" #include "llvm/Instructions.h" #include

i am getting seg fault on functions like I->eraseFromParent also. I'm assuming that the problem comes when i change the loop structure.
