* Add ADT/IntEqClasses.h as a light-weight implementation of EquivalenceClasses.h.Jakob Stoklund Olesen2010-12-211-0/+69
This implementation already exists as ConnectedVNInfoEqClasses in LiveInterval.cpp, and it seems to be generally useful to have a light-weight way of forming equivalence classes of small integers. IntEqClasses doesn't allow enumeration of the elements in a class. llvm-svn: 122293
