clang-p2996/llvm/test/Transforms/SLPVectorizer/RISCV/strided-loads-vectorized.ll
Alexey Bataev 833a1cadeb [SLP]Add support for strided loads. 
Added basic support for strided loads support in SLP vectorizer.
Supports constant strides only. If the strided load must be
reversed, applies -stride to avoid extra reverse shuffle.
