I had some problems adding the address of a jump table to the constant pool. The problem is that the address of a jump table is not a GlobalValue.Currently I decided to expand BRIND so that I can work on simpler problems :-) A small brain dump on the issue: GlobalValues are currently used to represent functions and global variables. Maybe we could also use then for anything that will have a label
