Evan Cheng d1d6b5cce2 For each loop, keep track of all the IV expressions inserted indexed by ... stride. For a set of uses of the IV of a stride which is a multiple of another stride, do not insert a new IV expression. Rather, reuse the previous IV and rewrite the uses as uses of IV expression multiplied by the factor. e.g. x = 0 ...; x ++ y = 0 ...; y += 4 then use of y can be rewritten as use of 4*x for x86. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@26803 91177308-0d34-0410-b5e6-96231b3b80d8		2006-03-16 21:53:05 +00:00
