The generic (concatenation) loop unroller is currently placed early in the standard optimization pipeline. This is a good place to perform full unrolling, but not the right place to perform partial/runtime unrolling. However, most targets don't enable partial/runtime unrolling, so this never mattered. However, even some x86 cores benefit from partial/runtime unrolling of very small loops, and follow-up commits will enable this. First, we need to move partial/runtime unrolling late in the optimization pipeline (importantly, this is after SLP and loop vectorization, as vectorization can drastically change the size of a loop), while keeping the full unrolling where it is now. This change does just that. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@205264 91177308-0d34-0410-b5e6-96231b3b80d8 |
