I was able to solve that but still crashing with the same error saying "Unreachable executed". I have attached the output with this mail. Thanks in advance.

Yes. Intially the pass was crashing when the module when the module verifier was running. I was able to solve that and now it is crashing when the bit writer pass is running.

...ally, tt was not a problem with the verifier, we were just inserting a wrong instruction in our pass. Also we were able to figure out the error you pointed out and our pass is running as intended!!! Thanks a lot.

...ter the transformation llvm runs BitCode Writer pass , which is aborting with Unreachable Executed error. I have attached the input llvm code and the output llvm code for reference. I am stuck at this problem for a few days now. Please let me know if you are able to find anything unusual.

...e the 'or' instruction is actually not needed(dead code), I replaced all occurences of %7 with %5. Now, the 'or' instruction should get deleted. How can I call Dead Code Elimination pass of LLVM from my pass or is there any method to remove that 'or' instruction? Thank you.

Hi everyone, I am trying to add some optimizations to LLVM's PTX backend. But i am unaware of the existing optimizations. Can you please guide me about the same?

Hi everyone, Are there any functions to identify the initiation,condition and iteration part of the loop? Example: for(i=0;i<10;i++) { a[i]+=1; } I want to know the name of the variable used in the loop(i) , the initiation(i=0), condition(i<10) and the iteration(i++) part of the loop. Thank you:) -------------- next part -------------- An HTML attachment was scrubbed... URL:

Hi Adarsh, to my knowledge there is no publicly available CUDA-Frontend for LLVM yet. The work of Helge Rhodin you mentioned is on the backend-side: It allows to generate PTX code from LLVM IR. It is still being maintained, although I think the currently available source code is a little outdated. There i...

Hello , How to execute a cuda program using llvm? More specifically, nvcc produces some temporary files during its compilation. I want to convert the .cu.cpp to .ll format and optimize it. The .cu.cpp file contains typedefs and enums used by cuda runtime and also the host part of the code and the ptx file contains the kernel definition. How can i run the program after optimization? Will Rhodin

Hi, Please let me know how to follow my pass in LLVM by Dead Code Elimination pass of LLVM. getAnalysisUsage(...) only allows me to run passes before my pass. I want to run Dead Code Elimination pass after my pass. Regards, Adarsh -------------- next part -------------- An HTML attachment was scrubbed...

...terested in obtaining the instruction that defines/allocates the value of interest. Once we obtain that we can use LoopInfo pass to check whether the basic block containing that definition instruction belongs to the loop in question. Is there a method that returns the defining instruction?

Is there a way to insert a function at the start of a module rather than inserting it at the end, which happens by default? -- Adarsh Yoga Graduate Student, Computer Science Indiana University, Bloomington -------------- next part -------------- An HTML attachment was scrubbed...
