Roman Tereshin cc01a9a147 [LSV] Look through selects for consecutive addresses ... In some cases LSV sees (load/store _ (select _ <pointer expression> <pointer expression>)) patterns in input IR, often due to sinking and other forms of CFG simplification, sometimes interspersed with bitcasts and all-constant-indices GEPs. With this patch`areConsecutivePointers` method would attempt to handle select instructions. This leads to an increased number of successful vectorizations. Technically, select instructions could appear in index arithmetic as well, however, we don't see those in our test suites / benchmarks. Also, there is a lot more freedom in IR shapes computing integral indices in general than in what's common in pointer computations, and it appears that it's quite unreliable to do anything short of making select instructions first class citizens of Scalar Evolution, which for the purposes of this patch is most definitely an overkill.
