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

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, For the following code const Type * Int32Type = IntegerType::getInt32Ty(getGlobalContext()); AllocaInst* newInst = new AllocaInst(Int32Type, 0, "flag", Bb); Bb->getInstList().push_back(newInst); It gives me the error " error: no matching constructor for initialization of 'llvm::AllocaInst' AllocaInst* newInst = new

Hi, I am working on a project with LLVM. What I need to do is to generate/insert some dummy/dead basic blocls which never have chance to be executed and put some instructions in those dummy/dead basic blocks. So far, the dummy/dead BB insertion is done. I am trying insert instructions in those dummy/dead BB. Actually, I can insert the legal instructions to dummy/dead BB, however, I really want

We are trying to create RHEL6.1 container and having trouble getting a proper console to the container. I have used lxc containers in the past and lxc has a script (lxc-fedora) to setup a basic Fedora container. Is there something similar or docs with virtmgr ? We started out making a copy of the root fs and using that copy as the root for the container. I made a couple of tweaks to the

Hi , I am trying to clone a BasicBlock. I want both to co-exist and I have introduced a conditional branch to the original or the cloned BB. I tried mapping the original instruction and the clone as below : Instruction *NewInst = II->clone(); if (II->hasName()) NewInst->setName(II->getName()); NewBB->getInstList().push_back(NewInst); ValueMap[II] =

Hi, Nick, thanks for the reply. I still have a problem: I only need to "clone" an Instruction, changing its type. That is, I would like to keep all characteristics of the old Instruction and create a new one only with a different type. I am trying create a new Instruction thus: %3 = add nsw i32 %1, %2 ; <i16> [#uses=2] //Old Instruction Value* Op0 = I->getOperand(0); Value*

iMac Intel Core Duo; OS X 10.4.8; Java 1.5.0_06; R 2.4.1; JGR 1.4-14; rJava 0.4-12; iplots 1.0-5 I'm unable to get JGR or iplots to load using "library(JGR)" or "library(iplots)", respectively. This feels like it might be a classpath or Mac look-and-feel issue, but I'm not sure where to go with it at this point. I've searched the fora and web to no avail. Any

Hello everyone, is there any way to replace an instruction inside LLVM that is more elegant than creating a new one, replacing uses and deleting the old one if I only want to modify the type? It is generally not a big deal, but the issue gets really messy if I am in the middle of iterating over uses and start deleting some of them... I hope I could describe my problem well enough ;) Regards,

It seems the CloneBasicBlock function defined in Transforms/Utils/Cloning.h doesn't change the parent BasicBlock of the contained instructions when it has cloned them -- Is this a bug or a feature? m.

I'm not sure I understand. This code: Instruction *NewInst = II->clone(); ..

Well, it does so to implement Arnold and Ryder style profiling. I can send you a copy of that if you want (I hope to

Hi, I need to insert new instruction into every basic block like x=1 or while loop I tried this code, but it doesn't work Type * Int32Type = IntegerType::getInt32Ty(getGlobalContext()); AllocaInst* newInst = new AllocaInst(Int32Type,"flag", Bb); Bb->getInstList().push_back(newInst); the error: void llvm::SymbolTableListTraits<llvm::Instruction,

Hello Andrew , Yes , I have missed the phi node since my paths merge together. I'll try this out. I am implementing a timer based profiling scheme and hope your code will be useful for me.

HI, I am creating a pass that will pass loaded value by load instruction to an external function. I don't know how to do it.Please Help.

Try : INITIALIZE a1 if you didnt. if (cpProf EXISTS){ CallInst* newInst = CallInst::Create(cpProf,a1,""); if (BB->getTerminator() && CI) BB->getInstList().insert((Instruction*)CI, newInst); On Tue, Mar 5, 2013 at 1:04 PM, Anshul Garg <gargaa24 at gmail.com> wrote: > CallInst* newInst = CallInst::Create(cpProf,a1,""); >
