Hi Zhoulai, I am trying to modify "LoopUnrollPass" in llvm which produces multiple copies of loop equal to the loop unroll factor.Currently, using multicore architecture, say 3 for example and the execution goes like: for 3 cores if there are 9 iterations of loop core instruction 1 0,3,6 2 1,4,7 3 2,5,8 But I want to to

Hi All, Thank you for your suggestions. @Michael: I tried your suggestion. I could run "Loop Vectorizer" successfully. But my problem is not solved. @Renato: I want to do the 1st type operation: 1) Use all cores, dividing the loop into multiple cores, one block at a time. But I don't want to use "OpenMP" for this. I don't want the user to mention OpenMP command
