similar to: [LLVMdev] store the LLVM-bitcode from a pass

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

Hello together, I use the "opt" as following, to run my pass, which modifies the LLVM-IR by inserting instructions in basic-blocks. opt -load ..../Decorator.so -dec <prog.bc> /dev/null how can i store the modified bitcode on the disc (as bitcode or as human-readable assembly)?

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,

Hi, As far as I know, Instruction class does not inherit "Annotable" Class. Only Function 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,

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

Hi Eli, I want to disable optimizations because, i'm going to implement a framework in JAVA for educational purposes. I have planned to do followings: 1) Create LLVM-IR and export it as Assembly (without optimizing the source-code) 2) Transform the LLVM-Assembly to a data-structure, similar to LLVM data structure (Module, Function, BB ...) but implemented in Java 3) Optimizing

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... URL:

Hello together, although i use the "-O0" flag as follow, the llvm perform dead code elimination. How can i disable optimizing completely?

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 of my

That isn't really analysis;

Sorry, it's not possible; the gcc front-end does some optimizations which the LLVM backend can't do anything about, and dead code

Hi, i need a sample-code, for which the llvm alias-analysis finds a *must-aliases*. I have tried codes like followings. In all cases, i see just *may-aliases* when i use "opt -aa-eval -print-all-alias-modref-info foo.bc": Regards Raad 1 ========================================== void foo() { int i = 2; int& r = i; } 2 =========================================== void

Hi together, i want to create a map containing a set of aliases for each value. For example, for a code like: int main() { int i; int *p1 = &i; int *p2 = &i; return 0; } the map should contain something like: {i --> (p1, p2), ..... } For that, i do followings in my pass: AliasAnalysis &AA = getAnalysis<AliasAnalysis>(); AliasSetTracker *tracker =

Hi, In my pass, I want to use the alias-analysis info provided by "GlobalsModRef". How should I use "getModRefBehavior(...)"-method and "alias(...)", in order to get the best presicion? More precisely, how can I find the required arguments, particularly "PointerAccessInfo", for this methods. And is it a good idea to use "GlobalsModRef" in the

Hello together, the llvm is supposed to perform install-time optimization. How is it possible, where the IR contains no machine-specific information?
