Matthias Braun 6054e84d82 LiveIntervalAnalysis: Rework constructMainRangeFromSubranges() ... We now use LiveRangeCalc::extendToUses() instead of a specially designed algorithm in constructMainRangeFromSubranges(): - The original motivation for constructMainRangeFromSubranges() were differences between the main liverange and subranges because of hidden dead definitions. This case however cannot happen anymore with the DetectDeadLaneMasks pass in place. - It simplifies the code. - This fixes a longstanding bug where we did not properly create new SSA values on merging control flow (the MachineVerifier missed most of these cases). - Move constructMainRangeFromSubranges() to LiveIntervalAnalysis and LiveRangeCalc to better match the implementation/available helper functions. This re-applies r269016. The fixes from r270290 and r270259 should avoid the machine verifier problems this time. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@270291 91177308-0d34-0410-b5e6-96231b3b80d8		2016-05-20 23:14:56 +00:00
