[LLVMdev] constantexpr problem

Hi all,
   I have got a problem when I used the use_empty() member function while I
used a global variable. I erase all the instructions which will use a global
variable. Then I called the use_empty() on that global variable. I got no
empty because a constantexpr use the global variable. I wonder whether there
is any way to erase the constantexpr which is useless to me but occupying
the global variable.
  best regard!

                                                  yours. Tsingray
