2011-05-17Tweak cross-class coalescing to be more aggressive when the target class is ↵Jakob Stoklund Olesen
small. The greedy register allocator has live range splitting and register class inflation, so it can actually fully undo this join, including restoring the original register classes. We still don't want to do this for long live ranges, mostly because of the high register pressure of there are many constrained live ranges overlapping. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@131466 91177308-0d34-0410-b5e6-96231b3b80d8

2011-05-16Teach LiveInterval::isZeroLength about null SlotIndexes.Jakob Stoklund Olesen
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
