llvm dev - May 2009 - [LLVMdev] using bugpoint

I am trying to use bugpoint to reduce the bytecode for a bug in one of 
my transformations.  Normally I run opt as such:

opt -load=libmine.so -mypass -param1 -param2 -o b.bc a.bc

Here, -mypass specifies a pass and -param1 and -param2 are just 
parameters that -mypass uses.  I added them using the command line 
parsing library that llvm supports.  I tried running bugpoint with the 
following:

bugpoint -load=libmine.so a.bc -mypass -param1 -param2

However, bugpoint always eliminates -param1 and -param2 from the list 
and runs into an assertion that will currently always happen if -param1 
and -param2 are not specified.  I have also tried to put --args -- in 
front of -param1 -param2 and --tool-args -- in front of -param1 -param2, 
and neither have helped.  How do I force bugpoint to keep the -param1 
and -param2?
