* Update the file headers across all of the LLVM projects in the monorepoChandler Carruth2019-01-191-4/+3
| | | | | | | | | | | | | | | | | to reflect the new license. We understand that people may be surprised that we're moving the header entirely to discuss the new license. We checked this carefully with the Foundation's lawyer and we believe this is the correct approach. Essentially, all code in the project is now made available by the LLVM project under our new license, so you will see that the license headers include that license only. Some of our contributors have contributed code under our old license, and accordingly, we have retained a copy of our old license notice in the top-level files in each project and repository. llvm-svn: 351636
* 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
