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 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

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

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

Hi, In fact I have some theory on instruction level parallelism( i have a partitioning algorithm), then first of all, i want to generate a multithreaded code from LLVM IR (in assembly level) with a given partitioning. My problem is how can i use a thread library(like Pthread) or OS system calls in LLVM IR to create and manage threads? --- On Tue, 10/5/10, Tobias Grosser <grosser at

Hi neda 8664, > how i can assign instruction of program to a thread? LLVM doesn't have special support for threads, you need to call library functions the same as you would from C. I suggest you write some C code that does what you want, then run it through http://llvm.org/demo/ to see the corresponding LLVM IR. Ciao, Duncan.

However, if you limit yourself for the moment to loops that fit into the polyhedral model, you can take

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:

How does the verifier deal with this? I'm noticing that if I load a clang compiled function (with -emit-llvm) and run the verifier, there is no problem. If I start mucking with the function body (adding an instruction), the verifier is unhappy saying the instructions that would have been in the commented out block aren't part of a basic block. Does the clang compiled function have some

We try to use llvm to translate and generate the native code in parallel with multi-thread. But some various bugs will be triggered. We run the following code in multithread environment: ################## BasicBlock::Create(_CTX(), "dispatch", cpu->cur_func, 0); BranchInst::Create(bb_start, label_entry); cpu->exec_engine->getPointerToFunction ##################3 And cpu

A simulator should be expecting the machine opcodes not macros. LD shouldn't care at all as long as the object format plays well. I would think it would be better to fix the simulator.

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...
