If a loop has a constant trip count known to be a multiple of MaxVF (times user UF), LV infers that no tail will be generated for any chosen VF. This relies on the chosen VF's being powers of 2 bound by MaxVF, and assumes MaxVF is a power of 2. Make sure the latter holds, in particular when MaxVF is set by a memory dependence distance which may not be a power of 2. Differential Revision: https://reviews.llvm.org/D80491 |
