* Remove uses of builtin comma operator.Richard Trieu2016-02-181-4/+9
| | | | | | Cleanup for upcoming Clang warning -Wcomma. No functionality change intended. llvm-svn: 261270
* IntEqClasses: Let join() return the new leaderMatthias Braun2016-01-081-1/+3
| | | | | | | | The new leader is known anyway so we can return it for some micro optimization in code where it is easy to pass along the result to the next join(). llvm-svn: 257130
* Use IntEqClasses to compute connected components of live intervals.Jakob Stoklund Olesen2010-12-211-0/+1

* 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
