Jakob Stoklund Olesen f5497fb1b4 Teach LiveInterval::isZeroLength about null SlotIndexes. ... When instructions are deleted, they leave tombstone SlotIndex entries. The isZeroLength method should ignore these null indexes. This causes RABasic to sometimes spill a callee-saved register in the abi-isel.ll test, so don't run that test with -regalloc=basic. Prioritizing register allocation according to spill weight can cause more registers to be used. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@131436 91177308-0d34-0410-b5e6-96231b3b80d8		2011-05-16 23:50:05 +00:00
