Evan Cheng 1f300190f3 If the live interval legnth is essentially zero, i.e. in every live range ... the use follows def immediately, it doesn't make sense to spill it and hope it will be easier to allocate for this LI. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@28217 91177308-0d34-0410-b5e6-96231b3b80d8		2006-05-10 22:30:41 +00:00
