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:

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 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.

Hello, I am trying to print out output name of "unnamed temporary". For instance, for %3 = add i32 %21, i32 %index.01, I would like to print out %3. Can anybody please let me know how I can get it?

Hi Star Tan, Polybench should already be part of the LLVM test-suite. It has been contributed by Douglas do Couto Teixeira <douglasdocouto at gmail.com> and is available in SingleSource/Benchmarks/Polybench/. You should be able to just take advantage what is already available. Cheers, Tobi

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

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

Hi Surinder, Did you remember to #include "llvm/Analysis/Dominators.h"?

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. Surinder struct Dfl : public FunctionPass { raw_ostream *Out; static
