Hello together, how can i insert annotations in IR ? I want actually write something like: CallInst *call = CallInst::Create( ??? , aBasicBlock); in my pass.

Ok, but what about a pass like alias-analysis. How are the results stored, so that other passes can use them. -Raad ________________________________ From: Eli Friedman <eli.friedman at gmail.com> To: LLVM Developers Mailing List <llvmdev at cs.uiuc.edu> Sent: Tuesday, February 17, 2009 9:52:58 AM Subject: Re: [LLVMdev] information-transfer between analysis-pases On Tue, Feb 17, 2009 at 12:46 AM,...

Hello together, I have seen that the analysis-results are stored in llvm-IR as annotations. For example <; preds = %entry> in basicBlock level and <; <i32*> [#uses=2]> for a variable. Is there any documentation about annotations? Regards Raad -------------- next part -------------- An HTML attachment was scrubbed...

...n inherits annotable according to the documentation of annotable class. What you are asking would require adding annotations at instruction level, which does not seem to be possible. You can maintain external maps between instructions and your annotations, --Kapil On Thu, Mar 5, 2009 at 7:17 PM, RAAD B <raad_7007 at yahoo.com> wrote: > Hello together, > > how can i insert annotations in IR ? > > I want actually write something like: > > CallInst *call = CallInst::Create( ??? , aBasicBlock); > > in my pass. > > > Regards > Raad > > > > &g...

Hello. I read following article in this ML. I'm implementing the library similar with RAAD's plan. - AST node classes for LLVM-IR - LLVM-Assembly writer class - 100% pure Java - Without any optimizations - Without any frontends (parsers) I would like to release my library publicly if all problems below could be solved. (Although it is in the early stage) My library is the mixture...

I am new to llvm and am stuck up with a problem. I am trying to initialize a Value* of type fp128 having the value 0 I am using the following construct ConstantFP::get(APFloat(APInt(128,0,false))); This is returning a double instead of a float and I am confused. Thanks a lot for your help. -- -- Aparna -------------- next part -------------- An HTML attachment was scrubbed... URL:

Hi, take a look inside the file new_prog.bc. How does it start? Ciao, Duncan.

...required arguments, particularly "PointerAccessInfo", for this methods. And is it a good idea to use "GlobalsModRef" in the "doInitialization" of a function-pass? Or it should be at best be used in a "runonModule" of a module-pass ? many thanks in advance Raad -------------- next part -------------- An HTML attachment was scrubbed...
