[LLVMdev] Adding structures in a loop pass

     I wanted to do some speculative execution on a loop for which I
require some data storage structure for book keeping. The exact
structure of this storage buffer can only be determined after loop
analysis. Is there a clean way to add this new structure to the
module. Since this structure is to be used for each loop iteration I
do not want to allocate it inside the loop.

    A second alternative could be I run a module pass and go through
the loop inside that. Is there a way to call the loop pass from inside
the module pass or obtain information about the loops present inside
the module and individually call the loop pass on them.

Thanks in Advance,
