David L Kreitzer 1233356719 Add a pass to optimize patterns of vectorized interleaved memory accesses for ... X86. The pass optimizes as a unit the entire wide load + shuffles pattern produced by interleaved vectorization. This initial patch optimizes one pattern (64-bit elements interleaved by a factor of 4). Future patches will generalize to additional patterns. Patch by Farhana Aleen Differential revision: http://reviews.llvm.org/D24681 llvm-svn: 284260		2016-10-14 18:20:41 +00:00
