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. Differential Revision: http://reviews.llvm.org/D5066 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@217528 91177308-0d34-0410-b5e6-96231b3b80d8	2014-09-10 17:58:16 +00:00
Hal Finkel	006183a936	LoopVectorizer: Don't attempt to vectorize extractelement instructions ... The loop vectorizer does not currently understand how to vectorize extractelement instructions. The existing check, which excluded all vector-valued instructions, did not catch extractelement instructions because it checked only the return value. As a result, vectorization would proceed, producing illegal instructions like this: %58 = extractelement <2 x i32> %15, i32 0 %59 = extractelement i32 %58, i32 0 where the second extractelement is illegal because its first operand is not a vector. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@193434 91177308-0d34-0410-b5e6-96231b3b80d8	2013-10-25 20:40:15 +00:00
