Lang Hames	4c052261de	Changed slot index ranges for MachineBasicBlocks to be exclusive of endpoint. ... This fixes an in-place update bug where code inserted at the end of basic blocks may not be covered by existing intervals which were live across the entire block. It is also consistent with the way ranges are specified for live intervals. llvm-svn: 91859	2009-12-22 00:11:50 +00:00
