This adds a basic cost model for interleaved-access vectorization (and a better default for shuffles), and enables interleaved-access vectorization by default. The relevant difference from the default cost model for interleaved-access vectorization, is that on PPC, the shuffles that end up being used are *much* cheaper than modeling the process with insert/extract pairs (which are quite expensive, especially on older cores). llvm-svn: 246824 |
