...l fix any iterator invalidation occurring with the for() loop. That may work, but if I had been writing this pass, I would probably have made it a FunctionPass to ensure that the CFG changes don't confuse the PassManager. -- John T. > > On Mon, Dec 12, 2011 at 7:54 PM, neda 8664 <neda8664 at gmail.com > <mailto:neda8664 at gmail.com>> wrote: > > Thank you for your reply > > Yes, I change them, so what should I do for another loops? > > > On Mon, Dec 12, 2011 at 7:42 PM, John Criswell > <criswell at illinois.edu <mailto:crisw...

hi all, I want access to all basic blocks of function in a loop, so I used the following code: *bool parallel::runOnLoop(Loop *L, LPPassManager &LPM) { for (Function::iterator bi= func->begin(); bi != func->end(); bi++){ // } }* First loop run without problem, but for second loop I get the following error: *0 libLLVM-2.9.so 0x0137d530 1 libLLVM-2.9.so 0x0137fa6c 2

I want automatically parallelize sequential program in thread level to run on multi-core processors with software pipelining and use llvm. is it a suitable tools in this project ? can you help me in this topic? -------------- next part -------------- An HTML attachment was scrubbed...

LLVM has no facility for dealing with threads explicitly. If you're implementing a research tool to automatically pipeline software, LLVM could be of use because it is also a JIT with a good API.

I've study their work carefully. My problem is the implementation of threads in llvm after partitionning. I want to have information about how to implement producer/consumer thread in llvm. I do not know where I should start in llvm for code generation and create thread and insert produce and consume statement . -------------- next part -------------- An HTML attachment was scrubbed...

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:

i need split a sequential program to multithread. the first step I am going to assign each basic block of program to a thread, so i want create a function for each basic block and add instruction of basic block into it and assign every function to a thread. how could i do it? -------------- next part -------------- An HTML attachment was scrubbed...

I use "opt -dot-cfg sample.bc" command to view cfg, but I encountered the following warning. WARNING: You're attempting to print out a bitcode file. This is inadvisable as it may cause display problems. If you REALLY want to taste LLVM bitcode first-hand, you can force output with the `-f' option. I see unmeaning thing when use -f , in additinal I've installed graphvis

Hi All I extract Def_Use chain by following code: for (Value::use_iterator i = F->use_begin(), e = F->use_end(); i != e; ++i) if (Instruction *Inst = dyn_cast<Instruction>(*i)) { errs() << "F is used in instruction:\n"; errs() << *Inst << "\n"; } Now, I want to distinguish the register name or memory variable that lead to

I am MSc student and my thesis subject is "parallelization of sequential program in thread level to run on multi-core processors". I want automatically parallelize sequential program in thread level to run on multi-core processors with software pipelining. I've use LLVM to code analysis and translate code to IR, I could extract PDG graph form IR code and convert it to SCCDAG and

hi i want replacing a global variable by a constant value for erase instruction. i had seen the code that as follows for (llvm::GlobalVariable::use_iterator U = gv->use_begin(); U != gv->use_end();--U ) { llvm::Instruction *I = llvm::cast<llvm::Instruction>(U); I->replaceAllUsesWith(constPtr); I->eraseFromParent(); } but i dont know how can declare constptr.
