similar to: [LLVMdev] int to StringRed conversion

I think the better solution should be: LLVMContext& C = is->getContext(); Value *values[] = { ConstantInt::getSigned(Type::getInt64Ty(C), *scsr*), MDString::get(C, *"path"*) }; lnstr.setMetadata(*"your_analysis_name"*, MDNode::get(C, values)); So that you can take advantage of the type system of LLVM bitcode, and don't have to cast the integers from/to strings

Yes, it sounds good. I can try tomorrow. Thank you for your advice !

The problem is that I want to pass only srsr which is an int. "marked" was just an example :) Thanks you!

Hi, I think you may try to use llvm::Twine(int). For example, to convert 30 to string, you can use: Twine(30).str() To convert the string back to integer, you can try the StringRef::getAsInteger(unsigned, APInt &). For example: APInt i; str.getAsInteger(/*radix=*/ 10, /*output=*/ i); Sincerely, Logan On Thu, May 2, 2013 at 9:53 PM, Alexandru Ionut Diaconescu <

Hello everyone, I want to pass a set of integers using metadata but I don't know how. I have tried: the integers are in array[] *1. * LLVMContext& C = is->getContext(); Value* values[size]; for(int gy=0;gy<size;gy++){ values[gy]=ConstantInt::getSigned(Type::getInt64Ty(C),array[gy]); } *is->setMetadata("path",MDNode::get(C,values));* failes when setMetadata(),

I also tried the following, with no compilation errors, but segfault, core dumped: *LLVMContext& C = is->getContext(); Value* values[size]; for(int gy=0;gy<size;gy++){ values[gy]=ConstantInt::getSigned(Type::getInt64Ty(C),array[gy]); } llvm::ArrayRef<Value*> bla = values[size]; is->setMetadata("path",MDNode::get(C,bla));* On Fri, May 3, 2013

Hi Alexandru, did you build LLVM with assertions enabled? If not then you should do. Ciao, Duncan.

Hello everyone, I was able to get all the execution paths between 2 points (basic blocks) in my program (with the condition to traverse a loop only once). I mapped all the basic blocks to integers and created a correspondent directed graph. I was able to get all the paths (a path is represented by an integer identifier). For my target program I have 72 paths, but the program hangs unexpectedly

Hello Duncan, Yes, I built it with assertions and I have also debug info.

Hi, I don't know much about this issue, but this malloc error won't be solved by a change to delete[] or free. In fact, if you use the incorrect one for simple types, you may not notice it. The error you have seems to me like a memory corruption because you went out of bound and corrupted the memory somewhere, Valgrind may help you figure out what is going on. Cheers, Matthieu

As an update, it is a memory problem which I don't know how to fix. I tried to skip the problematic piece of code when in the case when the loop hangs. So I did something like : if( instr ) { LLVMContext& C = instr->getContext(); Value* values[cnt]; errs()<<"\ngy: \n"; if(!(desters==7)){ // this

I solved by checking if(BB->size()>1) Thank you all for the help ! Now debugging the next segfault.

I think I understood that, but what I mean is what is the function responsible to do mapping is it MapValue() in ValueMapper.h?

Hello, Thank you for your answer. If I want to use then I have error: ‘NodeTy* llvm::ilist_half_node<NodeTy>::getPrev() [with NodeTy = llvm::Instruction]’ is protected error: ‘llvm::ilist_half_node<llvm::Instruction>’ is not an accessible base of ‘llvm::Instruction’ Do you know any other method to access the previous instruction of a terminator instruction?

What do you mean by mapping to integers?

I don't use a function for do the mapping, it may be MapValue(). If it does not work, alias an int identifier for each basic block. Be aware because basic block cannot have the same name (getName) in the same function, but they might have the same name being in different functions. Therefore, take into account the function name as well. Good luck On Thu, Jun 6, 2013 at 10:55 AM, Rasha Omar

But I don't want to map only basic blocks, I need too to map the edges "the whole CFG of the function" Save the CFG of the function in another memory address and call it for example orgCFG and change the CFG by referencing to the orgCFG Thank you for help and patience On 6 June 2013 10:59, Alexandru Ionut Diaconescu < alexandruionutdiaconescu at gmail.com> wrote: > I

I don't see any method like hasPrevNode. It can be a weird problem because "current->getPrevNode()" is indicating to "current" itself (the problem appears for the BB with only one element)?

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.

Hello everyone ! I followed http://stackoverflow.com/questions/4976298/modern-equivalent-of-llvm-annotationmanagerin order to get annotations from my target bytecode. All the examples that I give in the following is related to the code from that link. I have `__attribute__((annotate("DS"))) int f=0;` into the target C++ program and the related IR code: @.str = private unnamed_addr
