2004-03-30Fix a fairly major performance problem. If a PHI node had a constant asChris Lattner
an incoming value from a block, the selector would evaluate the constant at the TOP of the block instead of at the end of the block. This made the live range for the constant span the entire block, increasing register pressure needlessly. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@12542 91177308-0d34-0410-b5e6-96231b3b80d8

2004-03-29Don't warn about a null live range if the Value is a ConstantIntegral.Brian Gaeke
Otherwise, if you're in debugging mode, you get warnings for (apparently) every immediate constant in the function during reg. allocation. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@12538 91177308-0d34-0410-b5e6-96231b3b80d8
