llvm dev - Nov 2011 - [LLVMdev] how often doInitialization in Looppass is called?

Hi all

I want my Looppass add some global variables(only once) before processing
each loops(many times)in the module. Currently I add all global variables
in the doInitialization of Looppass. It seems that doInitialization is
called for each function of the module. Is it so?  How to make my pass
processing globals only once?
