However, when I check the enum of Type IDs, I see that 10 corresponds to tokens and not integers. enum value 11 corresponds to integers : http://llvm.org/docs/doxygen/html/cla...

Hello, I am writing an optimization pass which optimizes code based on an online pointer analysis algorithm and need to detect pointers which are pointing to derived types. I have not had any problem identifying pointers in general using isa<PointerType>(...), but I can't seem to figure out how I can make sure that the pointer is pointing to a scalar value and not a function, array,

...ne whether a pointer argument is actually an array being passed which contains scalar values, or simply a pointer with a single scalar value. In other words, I want to ignore functions that accept arrays as arguments.

...to me. Maybe you intented if (isa<PointerType>(allocated_type)) { size = sizeof(void*); } else { size = allocated_type->getPrimitiveSizeInBits() * 8; } but take a look at getPrimitiveSizeInBits' documentation to make sure that it is really what you want: http://llvm.org/doxygen/classllvm_1_1Type.html -- Óscar

Hello, I'm wondering if it's possible to dereference a PointerType. I have an AllocaInst and although I can find the number of elements allocated, (using Instruction::getOperand(0)), I can't find a way to get the size of each element. What I'd like to do is: AllocaInst *alloca; PointerType *ptr_type = dynamic_cast<PointerType*>(alloca); assert(ptr_type); Type

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

...sive** hack which is already broken if Subclass data is used for other things inside LLVM. Just in case someone asks, I can't change the frontend that produces the Module so I need a way of changing the address space numbers in a pre-existing LLVM module.

Thanks Duncan, Yes, it is a ConstantExpr! Thank you! Now trying to find a clue in ConstantExpr's functions to get that string :-) Regards, Welson On Thu, Jan 26, 2012 at 9:04 PM, Duncan Sands <baldrick at free.fr> wrote: > Hi Welson Sun, > > > Hi, if I have some LLVM code like this: > > > > @.str = private unnamed_addr constant [7 x i8]
