...rget-independent tests. Tests that rely on specific TTI hooks and instruction costs are placed under the target-specific directories. Target-independent tests are great because we don't have to replicate them for all targets. But we can write new transformations (e.g., https://reviews.llvm.org/D26083) that use the cost model to guide code generation in ways other than selecting the vectorization and interleave factors. That is, the code we generate can be different, depending on the target, even if we manually specify vectorization and interleave factors. So the question is, if we perform some...
