I am testing some software using mpsim.  I get the warning "Caution - register
file read before write"  I have eliminated most of them but am having trouble
finding one.  Is there a way to get mpsim to break at the instruction causing
this warning?  I know I could probably find it with enough looking thru the
code but if the tool can help, I'll let it.  BTW this one must be in a
infrequently executed segment since it occurs infrequently.

Thanks for any help.
