2012-10-21	Add support for reduction variables that do not start at zero.	Nadav Rotem
	This is important for nested-loop reductions such as : In the innermost loop, the induction variable does not start with zero: for (i = 0 .. n) for (j = 0 .. m) sum += ... git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@166387 91177308-0d34-0410-b5e6-96231b3b80d8
2012-10-19	Vectorizer: Add support for loop reductions.	Nadav Rotem
	For example: for (i=0; i<n; i++) sum += A[i] + B[i] + i; git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@166351 91177308-0d34-0410-b5e6-96231b3b80d8
