Hal Finkel 6a8a9c45cc [PPC/LoopUnrollRuntime] Don't avoid high-cost trip count computation on the PPC/A2 ... On X86 (and similar OOO cores) unrolling is very limited, and even if the runtime unrolling is otherwise profitable, the expense of a division to compute the trip count could greatly outweigh the benefits. On the A2, we unroll a lot, and the benefits of unrolling are more significant (seeing a 5x or 6x speedup is not uncommon), so we're more able to tolerate the expense, on average, of a division to compute the trip count. llvm-svn: 237947		2015-05-21 20:30:23 +00:00
