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

Hi, Andrey, sorry for the delay: I made a page with the code available for download: http://homepages.dcc.ufmg.br/~douglas/projects/RangeAnalysis/RangeAnalysis.html Feel free to get it, and if you need some help, I will be happy to tell you how to set the analysis up, in case the explanation in the page is not good. I also have a report describing the implementation here: (

Hi guys, I am trying to figure out how to use your Lazy Value Info pass, but I am having some questions. First, it seems that the implementation contains infra-structure to deal with range intervals, but the main interface only gives the client information about which values are constants. Is this true? Second, reading the code I see that the ranges are being computed, but I could not tell if

Can't you just compile the SPEC binaries and use a script in a scripting language of your choice to run them?

We were thinking of adding VRP to LLVM too, though we were mostly interested in Patterson's approach (i.e. not connected with SSI form). It

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*

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
