similar to: [LLVMdev] How to create a new Basic block

Please help me out. I am trying to create an empty basic block between two basic blocks. I am using splitedge function. But I am getting the o/p. The .ll file is not showing any output. -- regards, soumya prasad ukil -------------- next part -------------- An HTML attachment was scrubbed...

Look I have written a PRE pass. opt is running that pass. I have included my pass name there in include/llvm/Support/StandardPasses.h file. To do that, I have got some error. Because it also requires the definition of the pass in some other file also. I observed how gvn pre pass is added to the pass list. I had followed the same way, but failed. Cna you kindly tell what needs to be done in this

I have created a new basic block. Now I want to make copy of instructions from one basic block to another . How to do that ? -- regards, soumya prasad ukil -------------- next part -------------- An HTML attachment was scrubbed...

If you want to emit it during the code gen phase the EmitBlock

I want to do the following: suppose the program structure: bb / \ bb1 bb2 \ / bb3

Can you tell me where pass_1 is defined? You have used it inside getAnalysis<pass_1>(). Is it the name we generally give to a pass while registry? In this case, don't I need to use getAnalysisUsage (AnalysisUsage &AU) function?

I have written a simple pass. I have been successful to execute it. I want LLVM to execute it. I don't know how to include a pass in llvm actual pass list, such it automatically invokes it just like GVNPre pass or some other pass. They have already been limked in llvm actual pass list. -- regards, soumya prasad ukil -------------- next part -------------- An HTML attachment was scrubbed...

In LLVM, we generally use data structure of another pass by implementing getAnalysisUsage (AnalysisUsage &AU) method. Suppose SOURCE/lib/Transform directory I have added one pass named as pass_1, which calculates all expressions in a program and stores all of them in an Expr array(take it now for granted). Now I added another pass named as pass_2 in the same directory to print all these

Can you guys tell how to recognize local & global variables ?

How to recognize pointer variable & ordinary variable? I have tried with "isa<PointerType>(V->getType())", but failed. -- regards, soumya prasad ukil -------------- next part -------------- An HTML attachment was scrubbed...

Your last statement is correct. But still my stand does not change. I want to differentiate ordinary local variable & pointer variables. Let's have a program, int a,b,c,*ptr; I want to extract only the local variables. That's what my question was. I think it is clear now. cast<PointerType>(A->getType() > > )->getElementType() is not working. I am also getting error

Yeah that's true. But I want somewhat different. Through Instruction how do u know that? If an instruction like %a = alloca i32 is there, how to get the variable 'a' ? Then on that variable we can check as you have said Right? How to capture that variable ? On 21 July 2010 16:07, Duncan Sands <baldrick at free.fr> wrote: > Hi Soumya_Prasad_Ukil, > > > Can you guys

If I get a statement like, *p=10, and I want to know the variable which p is pointing to. How to know this? -- regards, soumya prasad ukil -------------- next part -------------- An HTML attachment was scrubbed...
