similar to: [LLVMdev] How to recognize pointer variable & ordinary variable

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

Hi Soumya_Prasad_Ukil, > How to recognize pointer variable & ordinary variable? I have tried with > "isa<PointerType>(V->getType())", but failed. I'm not sure what you are asking, but if you are asking whether an alloca instruction A represents local memory of pointer type, you can use A->getAllocatedType(). You can also use

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 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...

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?

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 ? Is there any macro on Value* defined in LLVM? -- regards, soumya prasad ukil -------------- next part -------------- An HTML attachment was scrubbed...

Is there a recommended way to retrieve the original type from an AllocaInst object? For example, I am creating alloca instructions using the IRBuilder interface like: alloca = builder.CreateAlloca( Type::getDoubleTy( context ), 0, variableName.c_str() ); and I place the alloca into a symbol table. Later when I am generating instructions for an assignment operation, I want to check the type of

Thanks Nick, Unfortunately, that is indeed what I asked for but not what I really am looking for. My naive approach is to store symbol table entries as Value* objects so I can allocate global variables and alloca variables and place them into the symbol table and the rest of the code didn't need to know which kind they were, in general. Loads and Stores of these types (as well as other

You should be able to use the second alternative that Nick proposed: cast<PointerType*>(pointer_value->getType())->getElementType() Reid On Fri, May 28, 2010 at 9:37 AM, Curtis Faith <curtis at curtisfaith.com> wrote: > Thanks Nick, > Unfortunately, that is indeed what I asked for but not what I really am > looking for. > My naive approach is to store symbol table

i am using llvm , i did this if ( AllocaInst *allocInst = dyn_cast<AllocaInst>(&*bbit)){ PointerType *p = allocInst->getType(); if ( p->getElementType()->isPointerTy()){ StringRef name = allocInst->getName();

I want to know the type of pointer . for example if we have int *p, struct node *w char *q then i want int for p,char for q , struct node for w. any help would be appreciated. -- View this message in context: http://llvm.1065342.n5.nabble.com/How-To-Get-The-Name-of-the-type-the-popinter-is-pointing-to-tp49121.html Sent from the LLVM - Dev mailing list archive at Nabble.com.

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

Sorry I have actually edited the post. I did check its type by using isa<PointerType>(cast<AllocaInst>(instr->getOperand(1))->getAllocatedType()) but it is only detecting i32** %b on line 8 of IR as a pointer type. Whereas I also want to detect the i32* %1 on line 11 of IR as a pointer type. So how can I do this?? -- View this message in context:
