Fix for a regression caused by the LoopVectorizer when

2013-07-08T21:20:34Z

vectorizing loops with memory accesses to non-zero address spaces. It simply dropped the AS info. Fixes PR16306.

Unfortunately, we skipped this check for if-convertable PHIs.

Do the same thing in some other places where we store pointers that could potentially be RAUW'ed.

Update the comment to mention that we use TTI.

LoopVectorize: Add support for floating point min/max reductions

2013-05-05T01:54:48Z

Add support for min/max reductions when "no-nans-float-math" is enabled. This allows us to assume we have ordered floating point math and treat ordered and unordered predicates equally. radar://13723044 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@181144 91177308-0d34-0410-b5e6-96231b3b80d8

LoopVectorizer: Cleanup of miminimum/maximum pattern match code

2013-05-05T01:54:44Z

No need for setting the operands. The pointers are going to be bound by the matcher. radar://13723044 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@181142 91177308-0d34-0410-b5e6-96231b3b80d8

LoopVectorize: We don't need an identity element for min/max reductions

2013-05-05T01:54:42Z

We can just use the initial element that feeds the reduction. max(max(x, y), z) == max(max(x,y), max(x,z)) radar://13723044 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@181141 91177308-0d34-0410-b5e6-96231b3b80d8
