[LLVMdev] Cast Pointer Address to Functions

[Xin Tong]

In fact i want to cast a uint64_t to a function address and make LLVM
generate IR to call it.

i.e. in LLVM IR, i want to generate something like this.

      the uint64_t  function prototype    function args
call 0xAABBCC    (void () (int int))        (1 , 2)

Thanks

Xin
