Dan Gohman 6bbcba18db Move the special cases for constants out of getUnknown and into ... createSCEV. Also, recognize UndefValue in createSCEV. Change getIntegerSCEV's comment to avoid mentioning FP types, and re-implement it in terms of getConstant instead of getUnknown. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@74041 91177308-0d34-0410-b5e6-96231b3b80d8		2009-06-24 00:54:57 +00:00
