Hi, Nick, thanks for the reply. I still have a problem: I only need to "clone" an Instruction, changing its type. That is, I would like to keep all characteristics of the old Instruction and create a new one only with a different type. I am trying create a new Instruction thus: %3 = add nsw i32 %1, %2 ; <i16> [#uses=2] //Old Instruction Value* Op0 = I->getOperand(0); Value*

Hi, guys, Thanks a lot for your help. As you know, I am trying to implement something to change the types of the instructions. And I chose the trunc's approach because it seems be simple. But I still have some problems and questions. Would be great if you can help me. I have used the results of my range analysis implementation to change the intermediate representation. I am using

Hello guys, I wonder how I can change the type of an integer variable. For instance, given the instruction "%3 = add i32 %1, %2" I would like to alter the instruction to "%3 = add i16 %1, %2". Is there any way to do this? Best wishes, Douglas -------------- next part -------------- An HTML attachment was scrubbed... URL:

Hi everybody, I saw that there are some instructions in the programs in which the flag nsw or nuw is placed. I wonder what rules does LLVM follows to put these flags in some instructions.

Hi guys, I have an analysis that is able to answer questions like this: given an integer variable, what is the interval of values that this variable can assume during the program's execution? I want to integrate this analysis into LLVM and it seems LVI (Lazy Value Info) is the best place to do this kind of stuff. Can someone give some hints about what I have to do to integrate my analysis

Dear LLVM community, I would like to contribute to LLVM in the Google Summer of Code project. My proposal is listed below. Please let me know your comments. Adding Range Analysis to LLVM Abstract The objective of this work is patch our implementation of range analysis into LLVM. I have a running implementation of range analysis in LLVM, but it is not currently part of the main distribution. I

Dear guys, I am in need of discovering induction variables in loops. Does LLVM provide a pass that already does this? For instance, given: int a = 0, i; for (i = 0; i < 10; i++) { a += 5; } I would like to know that variable 'a' depends on variable 'i'. Thank you very much, Douglas -------------- next part -------------- An HTML attachment was scrubbed... URL:

Hi all, PolyBench (http://www.cse.ohio-state.edu/~pouchet/software/polybench/) is a well-known benchmark for polyhedral compiler. Since LLVM-Polly http://polly.llvm.org/) has provided a very good polyhedral optimizer for LLVM, could we add this benchmark to LLVM test-suite? I have attached the patch file to add PolyBench to LLVM test-suite. Best wishes, Star Tan -------------- next part

I am creating a new pass (function pass) called Dfl from the Hello example and notes on "Writing an LLVM Pass". When I compile the program I get inncomplete type error (llvm/include/llvm/Pass.h:188: error: incomplete type 'llvm::DominatorTree' used in nested name specifier). The code is given below.
