Jakob Stoklund Olesen	396618b43a	Switch all register list clients to the new MC*Iterator interface. ... No functional change intended. Sorry for the churn. The iterator classes are supposed to help avoid giant commits like this one in the future. The TableGen-produced register lists are getting quite large, and it may be necessary to change the table representation. This makes it possible to do so without changing all clients (again). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@157854 91177308-0d34-0410-b5e6-96231b3b80d8	2012-06-01 23:28:30 +00:00
Jakob Stoklund Olesen	2b3fa322b8	Don't look for empty live ranges in the unions. ... Empty live ranges represent undef and still get allocated, but they won't appear in LiveIntervalUnions. Patch by Patrik Hägglund! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@156685 91177308-0d34-0410-b5e6-96231b3b80d8	2012-05-12 00:33:28 +00:00
Pete Cooper	789d5d85ba	Moved LiveRangeEdit.h so that it can be called from other parts of the backend, not just libCodeGen ... git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@153906 91177308-0d34-0410-b5e6-96231b3b80d8	2012-04-02 22:44:18 +00:00
Craig Topper	e4fd907e72	Use uint16_t to store register overlaps to reduce static data. ... git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@152001 91177308-0d34-0410-b5e6-96231b3b80d8	2012-03-04 10:43:23 +00:00
Jakob Stoklund Olesen	a8bd9a68f7	Sink spillInterferences into RABasic. ... This helper method is too simplistic for RAGreedy. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@147976 91177308-0d34-0410-b5e6-96231b3b80d8	2012-01-11 22:52:14 +00:00
Jakob Stoklund Olesen	ccc9581e8b	Move RegAllocBase into its own cpp file separate from RABasic. ... No functional change. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@147972 91177308-0d34-0410-b5e6-96231b3b80d8	2012-01-11 22:28:30 +00:00
