Hi, How do I find out if a branch instruction belongs to an if-else or a loop i.e it is a backedge. Thanks, Bhavani

..... Instruction does not dominate all uses! %tmp3 = add i32 %b, %a ; <i32> [#uses=2] store i32 %tmp3, i32* %0, align 4 Broken module found, compilation aborted! add is existing instruction in function. store is the instruction I have added to the function. How do I fix this now :(?

Hi all, I probably have a stupid question but I could not find out so please help me out here. I can use getOperand to get the operands of an instruction. Similarly, How do I get the result of an instruction? Thanks, Bhavani

...rror when I try to link to the EE by using LINK_COMPONENTS=engine in the Makefile. Without that line in the Makefile, my pass gets registered fine but it is not able to create EE(Error reading Symbol). So, how do I link LLVMExecutionEngine.o without causing the multiple registration error. thanks, Bhavani --- On Mon, 10/27/08, John Criswell <criswell at cs.uiuc.edu> wrote: > From: John Criswell <criswell at cs.uiuc.edu> > Subject: Re: [LLVMdev] Is it possible to use EE within optimization pass? > To: "bhavi63 at yahoo.com" <bhavi63 at yahoo.com>, "LLVM Dev...

...hen I execute using opt, I get the error that the pass is registered multiple times. I know that there has to be a way out of this. Please let me know how I should link/load the EE library files with my optimization pass. I hope the question is clear now.

...! I get it now. Thanks a lot ! I changed it to BitCastInst(AI,VoidPtrTy,"",j); And now I am getting the following error :(. I have been stuck with this error before also.

Bhavani, A simple way that I'm not sure is 100% guaranteed to work is if the branch is to an earlier or later basic block.

Why is it a bad signature :(? i8* is being passed to the function? Any ideas as to what could be wrong?

ok. I think I get it now. I need to create the instructions as you have given. For eg: I could pass Instruction*(for storing the result of this instruction) while creating the store instruction. This is what you meant rite??

Thanks! How do I cast the result to a string? I basically need to store the results of some instructions in a file.

...e in the Makefile, I get the Pass registered multiple times error. And if i dont use anything, it is not able to load the EE. It gives error loading symbol error. So, 1. Is it possible to use the EE within an optimization pass? 2. If it is possible, how do I do it? Please help me out here! Thanks, Bhavani
