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.

Hal Finkel	2350e9f6b7	[LoopVectorize] Propagate known metadata to vectorized instructions ... There are some kinds of metadata that are safe to propagate from the scalar instructions to the vector instructions (fpmath and tbaa currently). Regarding TBAA, one might worry about propagating it on if-converted loads and stores, because the metadata might have had a control dependency on the condition, and thus actually aliased with some other non-speculated memory access when the condition was false. However, this would be caught by the runtime overlap checks. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@213452 91177308-0d34-0410-b5e6-96231b3b80d8	2014-07-19 13:33:16 +00:00
