Michael Zolotukhin	6845cace0e	Apply loop-rotate to several vectorizer tests. ... Such loops shouldn't be vectorized due to the loops form. After applying loop-rotate (+simplifycfg) the tests again start to check what they are intended to check. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@223170 91177308-0d34-0410-b5e6-96231b3b80d8	2014-12-02 22:59:02 +00:00
Sanjay Patel	87c977a52b	Rename getMaximumUnrollFactor -> getMaxInterleaveFactor; also rename option names controlling this variable. ... "Unroll" is not the appropriate name for this variable. Clang already uses the term "interleave" in pragmas and metadata for this.

Matt Arsenault	407847f130	Don't use runtime bounds check between address spaces. ... Don't vectorize with a runtime check if it requires a comparison between pointers with different address spaces. The values can't be assumed to be directly comparable. Previously it would create an illegal bitcast. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@191862 91177308-0d34-0410-b5e6-96231b3b80d8	2013-10-02 22:38:17 +00:00
