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(); Type *type = allocInst->getOperand(0)->getType();; errs() << type->getName() << " " << name &l...

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.

Hello, I was wondering how you can identify whether or not an Argument is a pointer. The "isDereferenceablePointer" function for Values doesn't seem to be what I want (I don't care whether or not the pointer points to allocated memory or is suitably aligned). I want to be able to discern between: i32* %pArray and i32 %pArray Thanks in advance. - John

Hi all, as a LLVM beginner I would like to know how can i check the pointer types with different levels like int 32* and int 32**, int 32***? By using value->getType()->isPointerTy() i can just know they are pointers. But the dump results clearly show they are different. Is there a good way to calculate their actual point to levels? Thanks! Best regards, Shen -------------- next part -------------- An HTML attachment was scrubbed... URL: <http://lists.llvm.org/pipermail...

...It looks like it is complaining because it is trying to zero-extend an i64 (type Count->getType() returns i64) to an i32 (IdxTy). if (Count->getType() != IdxTy) { // The exit count can be of pointer type. Convert it to the correct // integer type. if (ExitCount->getType()->isPointerTy()) Count = CastInst::CreatePointerCast(Count, IdxTy, "ptrcnt.to.int", Loc); else Count = CastInst::CreateZExtOrBitCast(Count, IdxTy, "zext.cnt", Loc); // <= this line } -------------- next part -------------- An HTML attachment was scrubbed...

this is definitely a bug in AA. 225 for (auto I = CS2.arg_begin(), E = CS2.arg_end(); I != E; ++I) { 226 const Value *Arg = *I; 227 if (!Arg->getType()->isPointerTy()) -> 228 continue; 229 unsigned CS2ArgIdx = std::distance(CS2.arg_begin(), I); 230 auto CS2ArgLoc = MemoryLocation::getForArgument(CS2, CS2ArgIdx, TLI); AliasAnalysis.cpp:228 It ignores every argument because they are vectors of pointers, not pointers.

Hi All, I am trying to check if a Value type is a int32 pointer by using if(T == Type::getInt1PtrTy(Context, AS)) ... I am trying to understand the AS (address space). How do I get it? Thanks.

Hi, You don't need to care about address spaces to check for an int32*: if (T->isPointerTy()) { const Type* intT = cast<PointerType>(T)->getElementType(); if (intT->isIntegerTy() && intT->getPrimitiveSizeInBits() == 32) cout << "Yeah!" << endl; } Also, to create a pointer type, if you don't care about address space at all, use the...

You can use isPointerTy() in Type class. George On Mon, Aug 20, 2012 at 12:39 PM, John Backes <back0145 at umn.edu> wrote: > Hello, > > I was wondering how you can identify whether or not an Argument is a > pointer. The "isDereferenceablePointer" function for Values doesn't > seem to...

Let me explain my intention first. I want to retrieve the value (if isPointerTy() returns true) to be stored by a store instruction at run-time and pass on that value as either an unsigned int (64) or a pointer (char*) to an external function. The call to that function is inserted using IRBuilder.CreateCall(). Consider the code snippet below. ================================...

...tputArg and incorporating it the CCAssignFn interface allows a more straightforward implementation in the targets, in my view (for both our uses). It's also information that's readily available when InputArg/OutputArgs are being constructed. In your case: CCIf<"SourceTy->isPointerTy()", CCAssignToReg<[P1, P2]>>; I've got a patch which implements it for ARM and X86 (though not HFAs using the features yet, I'm still musing on the best interface to present there -- "HFA* byval" for target simplicity or "HFA" for user simplicity), I'...
