Matthew Simpson bcc32afd72 Reapply r257800 with fix ... The fix uniques the bundle of getelementptr indices we are about to vectorize since it's possible for the same index to be used by multiple instructions. The original commit message is below. [SLP] Vectorize the index computations of getelementptr instructions. This patch seeds the SLP vectorizer with getelementptr indices. The primary motivation in doing so is to vectorize gather-like idioms beginning with consecutive loads (e.g., g[a[0] - b[0]] + g[a[1] - b[1]] + ...). While these cases could be vectorized with a top-down phase, seeding the existing bottom-up phase with the index computations avoids the complexity, compile-time, and phase ordering issues associated with a full top-down pass. Only bundles of single-index getelementptrs with non-constant differences are considered for vectorization. llvm-svn: 257918		2016-01-15 18:51:51 +00:00
