Hi
I am wondering why the following variable has a PointerTy.
@foo.data = internal addrspace(3) global float 5.000000e+000, align 4
When I do a V->getType()->dump() on the variable its printed as
float addrspace(3)*
thanks
shrey

Hi Shrey, if you declare a global variable of type T, then the GlobalVariable object (call it G) always has type T*. It's a pointer to the memory in which the T is held. So to write a T value to the global, you can just store it to G.
