llvm dev - Feb 2012 - [LLVMdev] How to get the array size of GetElementPtrInst->getPointerOperand() ?

If I dump the Value of GetElementPtrInst->getPointerOperand(), I got this:

%a = alloca [10 x i32], align 16


Obviously, there should be a way to get the dimension and element type via
the "Value" returned from GetElementPtrInst->getPointerOperand(),
but how?

What kind of "Value" is this?


Thanks!
Welson

OK, figured out. The value is an Instruction, the AllocaInst.
