2013-01-09	Remove the -licm pass from the loop vectorizer test because the loop ↵	Nadav Rotem
	vectorizer does it now. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@171930 91177308-0d34-0410-b5e6-96231b3b80d8
2013-01-09	Cost Model: Move the 'max unroll factor' variable to the TTI and add initial ↵	Nadav Rotem
	Cost Model support on ARM. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@171928 91177308-0d34-0410-b5e6-96231b3b80d8
2013-01-04	LoopVectorizer:	Nadav Rotem
	1. Add code to estimate register pressure. 2. Add code to select the unroll factor based on register pressure. 3. Add bits to TargetTransformInfo to provide the number of registers. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@171469 91177308-0d34-0410-b5e6-96231b3b80d8
2012-12-23	CostModel: Change the default target-independent implementation for finding	Nadav Rotem
	the cost of arithmetic functions. We now assume that the cost of arithmetic operations that are marked as Legal or Promote is low, but ops that are marked as custom are higher. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@171002 91177308-0d34-0410-b5e6-96231b3b80d8
2012-10-31	LoopVectorize: Preserve NSW, NUW and IsExact flags.	Nadav Rotem

2012-10-27	1. Fix a bug in getTypeConversion. When a simple type is split, we need to ↵	Nadav Rotem
	return the type of the split result. 2. Change the maximum vectorization width from 4 to 8. 3. A test for both. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@166864 91177308-0d34-0410-b5e6-96231b3b80d8
